54 is 75% of what number?

Furkat [3]

<span>one way to solve this kind of problems is by doing a little bit of reversal 75 % * X = 54 75/100 * X = 54 (we move 75/100 to the right, since it's a fraction the top and bottom number will be reversed) X = 54 * 100/75 X = 5400 / 75 X = 72 Hope I helped! :) Cheers!</span>

14. Which of the following is true about given APQR given in Figure 7.82 to the right? a. p²+q²=² b. q²+r²=p² c. (p+q)²=r² d. p²

Cloud [144]

Answer :
a. p²+q²=r²

According to the Pythagorean theorem :
p²+q²=r² ,because this is a right triangle and r is the length of the hypotenuse.

Anne's potato salad recipe requires one pound of potatoes for every four people served. How many pounds of potatoes will Anne ne

Ierofanga [76]

Answer:

3.5 pounds for 14 people

Step-by-step explanation:

Given

1 pound = 4 people

Required

Determine the pounds for 14 people

Represent this with x; so, we have:

$1\ pound = 4\ people$

$x = 14\ people$

Cross Multiply

$x * 4 = 1 * 14$

$4x = 14$

Solve for x

$x = 14/4$

$x = 3.5$

<em>Hence, 3.5 pounds for 14 people</em>

A rectangle has one of its sides on the x-axis and corners of the opposite side on the piece of the parabola y = 12 − x 2 above

saw5 [17]

Answer:

$A(x) = 24x - 2x^3$

Step-by-step explanation:

first we need to visualize what the question is trying to represent

A rectangle with one of its sides on the x-axis
The corners of the opposite two sides of the rectangle intersect with a parabola

the equation of the parabola is $y = 12 - x^2$

the equation of the parabola can also be written as

$y = -x^2 + 12$ this shows that the parabola has a $\cap$ shape and the turning point (peak) lies at the y-axis at y = 12. The parabola is symmetric along the y-axis!

right corner of the lower side of the rectangle has the coordinates (x,0)

we can also say that the coordinates of the lower left side are (-x,0). This is because the parabola is symmetric along the y-axis.

Solution:

We have enough information to express the sides lengths of the rectangle:

1) Lower side, (L)

We'll name the lower side 'L' and since this is a rectangle, this side length is the same as the upper side.

The lower side coordinates are (-x,0) and (x,0). Hence the side length is the difference of the two coordinates.

$L = x-(-x)$

$L = 2x$

2) The Left and Right side have the same height (H)

since the the lower side is on the x-axis (y=0), the only side moving is the upper one, i.e the coordinates of the upper corners are (0,y) where $y = 12- x^2$ . The side length of either the left or right sides is $y$
