A sandwich costs $0.75 more than a container of milk. A customer buys 4 sandwiches and 4 containers of milk. The customer pays $7.00. What is the cost of a sandwich? Enter your answer in the box.

Answers

Answer 1

Answer:

Assume that the cost of the milk is x.

We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:

cost of sandwich = cost of milk + 0.75

cost of sandwich = x + 0.75


Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.

We will transform this into an equation as follows:

total cost = cost of 4 sandwiches + cost of 4 containers of milk

7 = 4(x+0.75) + 4(x)


Solve the above equation to get x as follows:

7 = 4x + 3 + 4x

7-3 = 8x

8x = 4

x = 0.5


Therefore:

cost of milk = x = $0.5

cost of sandwich = x+0.75 = 0.5+0.75 = $1.25

$1.25

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

Answers

Final answer:

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.

Kristina, 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?

Answers

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.

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).

Answers

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.

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.

Answers

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.

Final answer:

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.

Answers

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.

3/2

The rate of change is 3/2

Final answer:

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.

what is the x and y intercept
8y=-9x-12

Answers

Answer:

X-intercept:(-4/3,0)

Y-intercept:(0,-3/2)

Step-by-step explanation:




Final answer:

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).

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 = -3

What is the equation of the line –3x–2y=30 in slope-intercept form? y = mx + b is slope-intercept form Enter your answer in the box.

Answers

Answer:

y = -3/2 x -15

Step-by-step explanation:

–3x–2y=30

To get the equation is slope intercept form y=mx+b, we need to solve for y

Add 3x to each side

–3x+3x–2y=3x+30

-2y = 3x+30

Divide  by -2

-2y/-2 = 3x/-2 + 30 /-2

y = -3/2 x -15

The slope is -3/2 and the y interceot us -15

Which sequence is geometric and has `1/4` as its fifth term and `1/2` as the common ratio?

Answers

Answer:

4, 2, 1, [tex]\frac{1}{2}[/tex], [tex]\frac{1}{4}[/tex], .....

Step-by-step explanation:

Fifth term (a₅) =  [tex]\frac{1}{4}[/tex]

Common ratio (r) = [tex]\frac{1}{2}[/tex]

n = 5

The formula to find the [tex]n^{th}[/tex] term of a geometric sequence is

a₅ = a₁r⁽ⁿ⁻¹⁾

=> [tex]\frac{1}{4}[/tex] = a₁*[tex](\frac{1}{2})^{(5-1)}[/tex]

=> [tex]\frac{1}{4}[/tex] = a₁*[tex](\frac{1}{2})^{(4)}[/tex]

=> [tex]\frac{1}{4}[/tex] = a₁*[tex](\frac{1}{2})*(\frac{1}{2})*(\frac{1}{2})*(\frac{1}{2})[/tex]

=> [tex]\frac{1}{4}[/tex] = a₁* [tex]\frac{1*1*1*1}{2*2*2*2}[/tex]

=> [tex]\frac{1}{4}[/tex] = a₁*[tex](\frac{1}{16})[/tex]

Flip the sides of the equation

a₁*[tex](\frac{1}{16})[/tex] = [tex]\frac{1}{4}[/tex]

Multiply both sides by 16

a₁*[tex](\frac{1}{16})[/tex]*16 = [tex]\frac{1}{4}[/tex]*16

Cancelling out the 16's from the top and bottom of the left side

a₁ = [tex]\frac{16}{4}[/tex]

=> a₁ = 4

So, first term of the geometric sequence is 4.

Common ratio = [tex]\frac{1}{2}[/tex]

Second term = First term * Common ratio

                      = 4* [tex]\frac{1}{2}[/tex]

                      = [tex]\frac{4}{2}[/tex]

                      = 2

Third term = Second Term * Common ratio

                  = 2 * [tex]\frac{1}{2}[/tex]

                  = [tex]\frac{2}{2}[/tex]

                  = 1

Fourth term = Third Term * Common ratio

                    = 1 * [tex]\frac{1}{2}[/tex]

                    = [tex]\frac{1}{2}[/tex]

Fifth term (given) = [tex]\frac{1}{4}[/tex]

So, the geometric sequence would be

4, 2, 1, [tex]\frac{1}{2}[/tex], [tex]\frac{1}{4}[/tex], .....

Answers

.0625 pounds or 28.3495231 grams

Answer:

16

Step-by-step explanation:

We want to divide 1/2 pound in 8 equal parts

1/2 dividend by 8/1 is the same as  

1/2 multiplied by 1/8 =1•1/2•8=1/16

Each package will weigh 1/16 of a pound  

Or 1 ounce since 1 pound = 16 oz
