Chad's family traveled [tex]\frac{5}{8}[/tex] of the distance to his grandmother’s house on Saturday. They traveled [tex]\frac{1}{3}[/tex] of the remaining distance on Sunday. What fraction of the total distance to his grandmother’s house was traveled on Sunday?
a whole or 1, is when the numerator and denominator are the same, namely 2/2, 3/3, 10000/10000 is a whole.
on Saturday they travelled 5/8 of the way, now, the whole being 8/8, so if we take 5/8 from 8/8, we're simply left with 3/8, that's the remaining distance to grandmas house.
on Sunday they travelled 1/3 of that remaining amount, how much is that? well, is simply their product,
[tex]\bf \cfrac{3}{8}\cdot \cfrac{1}{3}\implies \cfrac{3}{3}\cdot \cfrac{1}{8}\implies \cfrac{1}{8}[/tex]

What is the solution to the equation 1 over 2 multiplied by n equals 8 ? (5 points) n = 10 n = 6 n = 4 n = 16
Answer: n=16
Step-by-step explanation:
The solution to the equation is n = 16.
The equation 1/2 * n = 8 can be solved by multiplying both sides by 2 to find n = 16.
To solve the equation 1/2 * n = 8:
Multiply both sides by 2 to isolate n: n = 8 * 2 = 16.
Therefore, the solution to the equation is n = 16.
a small airplane flies 750 miles with an average speed of 300 miles per hour. 1 hour after the plane leaves, a Boeing 747 leaves from the same point. both planes arrive at the same time, what was the average speed of the 747
Final answer:
To calculate the Boeing 747's average speed, you subtract the one hour it departs after the small plane from the total travel time of the small plane and divide the same distance of 750 miles by this new time. The 747's average speed is found to be 500 mph.
Explanation:
The question asks for the average speed of a Boeing 747 that departs one hour after a small airplane and arrives at the same time. The small airplane travels 750 miles at an average speed of 300 miles per hour (mph). To find the average speed of the 747, we first calculate the time it takes for the small airplane to reach the destination:
Time = Distance ÷ Speed = 750 miles ÷ 300 mph = 2.5 hours
The 747 leaves an hour later, so its travel time is 2.5 hours - 1 hour = 1.5 hours. The 747 covers the same 750 miles in this shorter time frame:
Average speed of 747 = Distance ÷ Time = 750 miles ÷ 1.5 hours = 500 mph
The computed result is that the 747's average speed is 500 mph to cover the same distance and arrive simultaneously with the small airplane.

its really simple just put them in from least to greatest then cross one off from each side until you get your middle number.
Pick the correct description of the line y=-5/3x
This line is in slope intercept form y = mx+b
Since we can write it as y = (-5/3)x + 0
m = -5/3 is the slope
b = 0 is the y intercept
The two points (0,0) and (3,-5) are on the straight line.
To rationalize the denominator of 2/square 13+ squared 11 , you should multiply the expression by which fraction?
Answer:
You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex]
Explanation:
To rationalize any expression, you must multiply it by its conjugate. A conjugate is defined as a similar expression to the original one but with an opposite sign
This means that:
The conjugate of a + b would be a - b
Now, the given expression is [tex]\frac{2}{\sqrt{13}+\sqrt{11}}[/tex]
Consider the denominator:
From the above, we can conclude that the conjugate of [tex]\sqrt{13}+\sqrt{11}[/tex] is [tex]\sqrt{13}-\sqrt{11}[/tex]
And, remember that we need to keep the value of the expression unchanged. This means that we must multiply both the numerator and the denominator by the same value
Therefore:
You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex] in order to rationalize the denominator
Hope this helps :)
Answer:
[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]
Step-by-step explanation:
We are given the following expression and we are to determine the expression that we need to multiply it with in order to rationalize the denominator:
[tex] \frac { 2 } { \sqrt { 13 } + \sqrt { 11 } } [/tex]
To rationalize its denominator, we must multiply it with its conjugate.
For the denominator of the given expression, its conjugate would be [tex] \sqrt { 13 } - \sqrt { 11 } [/tex].
So to rationalize the expression, we would multiply it with:
[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]
you are making a fresh fruit salad using cantaloupe how much cantaloupe (AP) would you have to order if you needed 15 pounds (EP) and if canaloupe has a 55 percent yield?
Answer:
You would need to order 28 pounds. (27.27...)
Step-by-step explanation:
Let x be the number of cantaloupe. Then, 0.55x-=15.
0.55x=15
55x=1500
11x=300
x=300/11
x=27.27...
To make fruit salad using cantaloupe, you would need to order 28 pounds (AP) if you only need 15 pounds (EP) and the cantaloupe has a 55% yield.
Explanation:To determine how much cantaloupe (AP) you would need to order, you need to consider the yield percentage. If the cantaloupe has a 55% yield, it means that 55% of the cantaloupe will be usable. So, you need to order more than 15 pounds (EP) to account for the reduced yield.
To calculate the amount of cantaloupe (AP) to order, you can use the formula:
AP = EP / Yield Percentage
Using the given values, the calculation would be:
AP = 15 pounds / 55% = 27.27 pounds
Rounded up to the nearest whole number, you would need to order 28 pounds of cantaloupe (AP) to obtain 15 pounds (EP) with a 55% yield.

Subtract.
(5x^2 - 3x - 2) - (-2x^2 - +10)
Express the answer in standard form.
Enter your answer in the box
Answer:
7x^(2)-3x+8
Step-by-step explanation:
(5x^(2) - 3x - 2) - (-2x^(2) - +10)
(5x^(2))- (-2x^(2))=7x^(2)
(- 2)-(+10)=+8
7x^(2)-3x+8
Final answer:
To subtract (-2x² + 10) from (5x² - 3x - 2), change the signs of the second polynomial and combine like terms. The final result is 7x²- 3x - 12.
Explanation:
The question asks to subtract one polynomial from another, specifically to subtract (-2x²+ 10) from (5x² - 3x - 2). The subtraction of polynomials involves changing the signs of the polynomial being subtracted and then combining like terms. The process will be as follows:
First, change the signs of the second polynomial: -(-2x²) becomes +2x², and -(+10) becomes -10.
Then, combine the like terms with the first polynomial: (5x² + 2x²) becomes 7x², -3x stays the same as there are no like terms, and (-2 - 10) becomes -12.
Therefore, the answer in standard form is 7x²- 3x - 12.

Step-by-step explanation:
See an algebraic equation to solve the problem. The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if that perimeter of the triangle is 90 cm?
Answer:
22.5
30
37.5
Step-by-step explanation:
You have to multiply each ratio part by x to get them properly set up to add to 90.
3x + 4x + 5x = 90 Combine the left side
12x = 90 Divide by 12
12x/12 =90/12 Do the division
x = 7.5
3x = 3*7.5 = 22.5
4x = 4*7.5 = 30
5x = 5*7.5 = 37.5
Total 90
Final answer:
The lengths of the sides of the triangle with a perimeter of 90 cm and sides in the ratio 3:4:5 are 22.5 cm, 30 cm, and 37.5 cm. This is found by setting up an equation with variable x representing the common multiplier for the ratio, solving for x, and then calculating each side's length.
Explanation:
To solve the problem of finding the length of each side of a triangle with sides in the ratio 3:4:5 and a perimeter of 90 cm, we first set up an algebraic equation. Let the sides of the triangle be 3x, 4x, and 5x, respectively. The perimeter is the sum of these sides, so we have the equation 3x + 4x + 5x = 90 cm. Simplifying this gives us 12x = 90 cm. To find the value of x, we divide both sides of the equation by 12, resulting in x = 90 cm / 12, which simplifies to x = 7.5 cm. Subsequently, the lengths of the sides are 3x = 22.5 cm, 4x = 30 cm, and 5x = 37.5 cm.
If the sum of two congruent lengths equal the length of a third side,then the triangle created is isosceles. Is this a true statement?
Answer:
False
Step-by-step explanation:
To form a triangle, the sum of any two sides must be LARGER than the length of the third side.
This question says the sum of two sides are equal to the length of the third side. This wouldn't form a triangle.
Final answer:
Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.
Explanation:
Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.
In an isosceles triangle, two sides have the same length (congruent sides) and the remaining side is different (non-congruent side).
For example, if we have a triangle ABC where AB = BC (congruent sides) and AC is a different length (non-congruent side), then the triangle ABC is isosceles.
