To find equivalent fractions for 1/12 and 3/8 using the least common denominator, multiply the numerator and denominator of each fraction by the appropriate factor to obtain fractions with a common denominator of 24.
Explanation:To find an equivalent fraction for 1/12 and 3/8 using the least common denominator, we need to determine the smallest multiple that both denominators (12 and 8) have in common. The least common multiple of 12 and 8 is 24.
To convert 1/12 to a fraction with 24 as the denominator, we need to multiply the numerator and denominator by 2:
1/12 = (1 * 2) / (12 * 2) = 2/24.
To convert 3/8 to a fraction with 24 as the denominator, we need to multiply the numerator and denominator by 3:
3/8 = (3 * 3) / (8 * 3) = 9/24.
Final answer:
The equivalent fractions with the least common denominator of 24 for 1/12 and 3/8 are 2/24 and 9/24, respectively.
Explanation:
To find an equivalent fraction for each fraction with the least common denominator (LCD), you first need to determine the LCD for 1/12 and 3/8. In this case, the LCD for 12 and 8 is 24. Then, you adjust each fraction to have the denominator of 24.
For 1/12: Multiply both the numerator and the denominator by 2 to get 2/24.
For 3/8: Multiply both the numerator and the denominator by 3 to get 9/24.
Therefore, the equivalent fractions with a common denominator of 24 are 2/24 and 9/24.
To understand equivalency in general, when you multiply the numerator and the denominator of a fraction by the same number, you are creating a fraction that represents the same value as the original.
what is the x and y intercept
8y=-9x-12
Answer:
X-intercept:(-4/3,0)
Y-intercept:(0,-3/2)
Step-by-step explanation:
The x-intercept is (-4/3, 0) and the y-intercept is (0, -3/2).
Explanation:To find the x-intercept of the equation 8y= -9x-12, we substitute y with 0 and solve for x. This gives us:
8(0) = -9x-12
0 = -9x-12
-9x = 12
x = -12/9
x = -4/3
Therefore, the x-intercept is (-4/3, 0).
To find the y-intercept, we substitute x with 0 and solve for y. This gives us:
8y = -9(0)-12
8y = -12
y = -12/8
y = -3/2
Therefore, the y-intercept is (0, -3/2).

Walking on his own, the distance, D, in feet, that Roberto can cover in M, minutes is given by the function D(m)=264m. When he walks on the moving sidewalk at the airport, the distance, A, in feet, that he can cover in m m minutes is given by the function A(m)=440m. Let B be the distance, in feet, that Roberto would travel on the moving sidewalk in m m minutes if he were standing still. Write a formula for B(m) in terms of D(m) and A(m).
Answer:
B(m)=A(m)-D(m)
B(m)=176m
Step-by-step explanation:
we are given
Walking on his own, the distance, D, in feet, that Roberto can cover in M, minutes is given by the function
D(m)=264m
When he walks on the moving sidewalk at the airport, the distance, A, in feet, that he can cover in m m minutes is given by the function
A(m)=440m
B is the distance, in feet, that Roberto would travel on the moving sidewalk in m minutes if he were standing still
moving sidewalk distance = standstill distance + walking distance
A(m)=D(m)+B(m)
so, we get
B(m)=A(m)-D(m)
now, we can plug values
B(m)=440m-264m
B(m)=176m
Final answer:
To find the distance B(m) that Roberto would travel on a moving sidewalk in m minutes if he stood still, one must subtract the function for walking alone D(m) from the function for walking on a moving sidewalk A(m). Thus, B(m) is calculated as B(m) = A(m) - D(m), resulting in B(m) = 176m.
Explanation:
The student needs to find the formula for the distance B(m) that Roberto would travel on the moving sidewalk in m minutes if he stands still, in terms of the functions D(m) and A(m). The function D(m) = 264m represents the distance Roberto covers by walking on his own in m minutes, and A(m) = 440m represents the distance covered while walking on a moving sidewalk.
Since A(m) represents the combined effect of walking and the moving sidewalk, and D(m) represents just walking, the difference A(m) - D(m) will give us the contribution of the moving sidewalk alone, while Roberto stands still. Thus, the formula for B(m) is:
B(m) = A(m) - D(m)
B(m) = 440m - 264m
B(m) = 176m
The formula B(m) indicates the distance Roberto would cover on the moving sidewalk if he did not walk and just stood still.
Find the perimeter and area of the polygon shown below. The polygon is a trapezoid made up of a rectangle and a right triangle. The rectangle is 20 feet long and 15 feet wide. The right triangle joins the rectangle at a side that is 15 feet wide, and this is the height of the triangle. The base of the triangle is 8 feet and the hypotenuse is 17 feet.
The perimeter of the polygon is 110 feet and the area is 360 square feet.
Explanation:The polygon consists of a rectangle and a right triangle. To find the perimeter, we add the lengths of all sides. The length of the rectangle is 20 feet and its width is 15 feet, so the perimeter of the rectangle is 2 * (20 + 15) = 70 feet. The length of the base of the right triangle is 8 feet and the hypotenuse is 17 feet. The other side of the triangle is the height, which is given as 15 feet. Therefore, the perimeter of the polygon is 70 + 8 + 15 + 17 = 110 feet.
To find the area, we calculate the area of the rectangle and the triangle separately and then add them together. The area of the rectangle is length * width = 20 * 15 = 300 square feet. The area of the right triangle is 0.5 * base * height = 0.5 * 8 * 15 = 60 square feet. Therefore, the area of the polygon is 300 + 60 = 360 square feet.

Jayla ate 75% of the jelly beans in the bag. If she ate 24 jelly beans how many were in the bag?
Answer:
32 jelly beans were in the bag
Step-by-step explanation:
We know 75% is 3/4 and that she ate 24, so divide 24 by 3 then multiply it by 4:
24/3= 8
8 x 4 = 32
Final answer:
By dividing the number of jelly beans Jayla ate (24) by 75% and scaling it up to 100%, we determine that the bag initially contained 32 jelly beans.
Explanation:
Jayla ate 75% of the jelly beans in the bag, which equaled 24 jelly beans. To find out how many jelly beans were in the bag originally, we need to find what amount corresponds to 100% if 75% is 24 jelly beans. We perform this calculation by dividing the amount eaten (24 jelly beans) by the percentage she ate (75%), and then multiplying by 100% to scale it up to the total amount.
The calculation goes as follows: (24 / 0.75) = 32. This means there were originally 32 jelly beans in the bag before Jayla ate any.

Write an equation of the line that passes through the points (1,1) (5,9)
Answer:
y = 2x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
To find m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (1, 1) and (x₂, y₂ ) = (5, 9)
m = [tex]\frac{9-1}{5-1}[/tex] = [tex]\frac{8}{4}[/tex] = 2
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
using (1, 1 ), then
1 = 2 + c ⇒ c = 1 - 2 = - 1
y = 2x - 1 ← equation of line

A sandwich store charges a delivery fee to bring lunch to an office building. One office pays $33 for 4 turkey sandwiches. Another office pays $61 for 8 turkey sandwiches. How much does each turkey sandwich add to the cost of the delivery? Explain how you know.
Answer:
$7. Based on the assumption that both offices paid the same amount for delivery, the difference in the total cost paid is due to the difference in the number of turkey sandwiches ordered, which is 4. The cost of each sandwich is a quarter of this difference in cost.
Step-by-step explanation:
In mathematical working, the explanation above can be written in the form of equations, where we work to solve the value of a variable. In this case, we are interested to find the value of t.
Define variables:
Let the cost of a turkey sandwich be $t while the delivery fee be $d.
Form 2 equations:
Assuming that the sandwich stores charges the same delivery fee for both offices,
4t + d= 33 -----(1)
8t + d= 61 -----(2)
Solve by elimination:
(2) - (1):
4t= 61 - 33
4t= 28
Divide both sides by 4:
t= 7
Thus, each turkey sandwich adds $7 to the cost of the delivery.
To find out how much each turkey sandwich adds to the cost of delivery, we need to determine the cost of delivery in both cases and subtract it from the total price paid by each office.
Explanation:To find out how much each turkey sandwich adds to the cost of delivery, we need to determine the cost of delivery in both cases and subtract it from the total price paid by each office.
For the first office, they paid $33 for 4 turkey sandwiches. Let's assume the cost of delivery is 'x'. So the equation to represent the total cost is: 4x + 33 = total cost.
Similarly, for the second office, they paid $61 for 8 turkey sandwiches. Let's assume the cost of delivery is 'y'. So the equation to represent the total cost is: 8y + 61 = total cost.
Now we can solve both equations to find the values of 'x' and 'y' which will represent the cost of delivery. Once we have those values, we can calculate how much each turkey sandwich adds to the cost of delivery by dividing the cost of delivery by the number of turkey sandwiches ordered.

Rachel is driving from New York to Dayton Florida a distance of 1034 miles. How Much Time Is Saved By Doing The Trip At An Average Speed Of 60mph as compared with 55 mph? Round to the nearest half hour
By increasing her speed from 55 mph to 60 mph, Rachel can save approximately 1.5 hours on her 1034-mile trip from New York to Dayton, Florida.
Explanation:The subject of this question is Mathematics, specifically dealing with the concept of speed, distance, and time. To answer your question, we need to calculate how long the trip would take at each speed and then find the difference.
First, we calculate the time taken when the average speed is 55 mph. The formula to calculate time is distance divided by speed. So, 1034 miles divided by 55 mph equals about 18.8 hours.
Next, we do the same for 60 mph. 1034 miles divided by 60 mph equals about 17.2 hours.
The difference between the two times will give the time saved by increasing the speed to 60 mph from 55 mph. So, 18.8 hours - 17.2 hours equals 1.6 hours, which is approximately 1.5 hours when rounded to the nearest half hour.
Therefore, Rachel can save about 1.5 hours driving at an average speed of 60 mph compared to 55 mph over the distance of 1034 miles.

Two triangles have altitudes of equal length. if the areas of these triangles have a ratio of 3:4 then the bases of the triangles have the ration of what?
show work pleaseeee
Final answer:
The bases of the triangles have a ratio of 3:4.
Explanation:
The areas of two triangles with equal altitudes have a ratio of 3:4. We can set up the equation:
A₁/A₂ = 3/4
Let's denote the bases of the triangles as b₁ and b₂. The formula for the area of a triangle is A = (1/2) * base * height. Since the altitudes are equal, we can write:
A₁ = (1/2) * b₁ * h
A₂ = (1/2) * b₂ * h
Substituting these equations into the ratio, we get:
(1/2) * b₁ * h / (1/2) * b₂ * h = 3/4
Cancelling out the height and simplifying, we find:
b₁ / b₂ = 3/4
Therefore, the bases of the triangles have a ratio of 3:4.

3/2
The rate of change is 3/2
The average rate of change of a function from x = 9 to x = 15 is calculated by the slope of the secant line, which is (f(15) - f(9)) / (15 - 9). Specific function values are needed to perform this calculation.
Explanation:To calculate the function's average rate of change from x = 9 to x = 15, you can use the formula for the slope of the secant line between these two points on the graph of the function. This is given by the difference in the function values at these points divided by the difference in x-values:
Average Rate of Change = (f(15) - f(9)) / (15 - 9).
You would need the specific function values f(15) and f(9) in order to calculate this. If the function is linear, like the one represented by f(x) = 7x, you would substitute these x-values into the function to get f(15) = 7*15 and f(9) = 7*9, and then perform the calculation. However, without the actual function values, we cannot complete this calculation.

ASAP what is the value of a number raised to the power of 1?
Final answer:
The value of any number raised to the power of 1 is the number itself, as it implies a single multiplication of the number by 1.
Explanation:
The value of a number raised to the power of 1 is always the number itself. This is because an exponent represents how many times to multiply the number by itself. When the exponent is 1, you are simply multiplying the number by 1, which does not change its value.
For example:
51 = 5101 = 10-31 = -3Kristina, Liz, and Heather all made cookies. Kristina made 2.4 dozen less than 6 times as many dozen as Heather. Liz made 1.8 dozen more than 5 times as many dozen as Heather. If Kristina and Liz made the same number of cookies, how many dozen cookies did Heather make?
Answer:
Based on the number of cookies each girl made and if Kristina and Liz made the same number of cookies, then Heather made 4.2 dozen cookies.
Step-by-step explanation:
In order to find the number of cookies that Heather made, you need to set up two equations that represent the number of cookies that Kristina and Liz each made. Since Kristina made 2.4 dozen less than 6 times as many dozen as Heather, we can represent that with the equation 6c - 2.4. Since Liz made 1.8 dozen more than 5 times as many dozen as Heather, we can represent that with the equation 5c + 1.8. We can set both equations equal to each other since Liz and Kristina made the same number, so 6c - 2.4 = 5c + 1.8. Solving for 'c', which represents how many dozen cookies Heather made, we get 4.2
Let's assign a variable to represent the number of dozens of cookies Heather made. We'll call this variable \( H \).
According to the problem:
- Kristina made \( 6 \times H - 2.4 \) dozen cookies.
- Liz made \( 5 \times H + 1.8 \) dozen cookies.
We are also given that Kristina and Liz made the same number of cookies, so we can set these two expressions equal to each other to find the value of \( H \):
\[ 6H - 2.4 = 5H + 1.8 \]
Now, we'll solve this equation for \( H \).
Step 1: Isolate the variable \( H \) on one side.
To do this, we'll first subtract \( 5H \) from both sides of the equation:
\[ 6H - 5H - 2.4 = 5H - 5H + 1.8 \]
\[ H - 2.4 = 1.8 \]
Step 2: Now we need to get \( H \) alone, so we'll add \( 2.4 \) to both sides:
\[ H - 2.4 + 2.4 = 1.8 + 2.4 \]
\[ H = 4.2 \]
So, Heather made \( 4.2 \) dozen cookies.
To ensure this is the correct number of dozens Heather made, we can plug this value back into the original expressions for Kristina and Liz's cookies to verify that they made the same amount:
Kristina: \( 6 \times 4.2 - 2.4 = 25.2 - 2.4 = 22.8 \) dozen cookies
Liz: \( 5 \times 4.2 + 1.8 = 21 + 1.8 = 22.8 \) dozen cookies
Both Kristina and Liz made 22.8 dozen cookies, confirming our solution that Heather made 4.2 dozen cookies.
The local market is selling fresh fruit in baskets. The weights and amounts charged are shown below. For fruit weighing greater than or equal to 0.01 pounds and less than or equal to 0.5 pounds, the amount charged is $2.00. For fruit weighing greater than 0.5 pounds and less than or equal to 1.0 pounds, the amount charged is $3.50. For fruit weighing greater than 1.0 pounds and less than or equal to 1.5 pounds, the amount charged is $5.00. For fruit weighing greater than 1.5 pounds and less than or equal to 2.0 pounds, the amount charged is $6.50. For fruit weighing greater than 2.0 pounds and less than or equal to 2.5 pounds, the amount charged is $8.00. Which graph represents the function described?
Answer:
The graph is shown below.
Step-by-step explanation:
Let x be the weight of fruit in pounds and P(x) be the price of fruit.
For fruit weighing greater than or equal to 0.01 pounds and less than or equal to 0.5 pounds, the amount charged is $2.00.
P(x) = $2.00 for 0.01 ≤ x ≤ 0.5
For fruit weighing greater than 0.5 pounds and less than or equal to 1.0 pounds, the amount charged is $3.50.
P(x) = $3.50 for 0.5 < x ≤ 1.0
For fruit weighing greater than 1.0 pounds and less than or equal to 1.5 pounds, the amount charged is $5.00.
P(x) = $5.00 for 1.0 < x ≤ 1.5
For fruit weighing greater than 1.5 pounds and less than or equal to 2.0 pounds, the amount charged is $6.50.
P(x) = $6.50 for 1.5 < x ≤ 2.0
For fruit weighing greater than 2.0 pounds and less than or equal to 2.5 pounds, the amount charged is $8.00.
P(x) = $8.00 for 2.0 < x ≤ 2.5
It is a piecewise floor function. We have open circle on left side of each floor except first floor because the sign of inequality in all other is < .
We have closed circle on right side of each floor because the sign of inequality is ≤ .
