Answer: 4 ft^2

Explanation:

1) Data:

a) Figure: square pyramid
b) Volume: 12 ft^3
c) base lenght: 3 ft

2) Formulas:

The formula for the volume of a pyramid is:

Volume = (1/3) * area of the base * height

The formula for the area of the base is:

area of the base = (base length)^2

3) Solution

From the volume formula: height = 3 * volume / area of the base

area of the base = (3 ft)^2 = 9 ft^2

height = 3 * 12 ft^3 / 9 ft^2 = 4 ft^2

Answer:

It is the second triangle.

Step-by-step explanation:

This is because the area of the square is given as 25^2 as the perpendicular, 144^2 as the base, and the hypotenuse is 169^2.

Length of the perpendicular = 5^2 (Because 25^2 / 5^2)

Length of the base = 12^2

Length of the hypotenuse = 13^2

So, the Pythagoras theorem is,

=> H^{2} = P^{2} + B^{2}

=> 13^{2} =12^{2} +5^{2}

This is true, because, 13*13 = 12*12 + 5*5

=> 169 = 144 + 25

=> 169 = 169

If my answer helped, kindly mark me as the brainliest!!

Thanks!!

Answer:

WXYZ can not be a rectangle because consecutive sides are not perpendicular to each other.

Step-by-step explanation:

The given vertices are W(-4,3), X(1,5), Y(3,1) and Z(-2,-1).

Plot these points on coordinate plane and draw the quadrilateral as shown below.

Slope=\dfrac{y_2-y_1}{x_2-x_1}

Using this formula, we get

m_{WX}=\dfrac{5-3}{1-(-4)}=\dfrac{2}{5}

m_{XY}=\dfrac{1-5}{3-1}=\dfrac{-4}{2}=-2

Now,

m_{WX}\times =\dfrac{2}{5}\times (-2)=-\dfrac{4}{5}\neq -1

Here, WX and XY are two consecutive sides of quadrilateral but the product of their slopes is not equal to -1. It means they are not perpendicular to each other.

Since, all interior angles of a rectangle are right angles, therefore, WXYZ can not be a rectangle.

If ab= 7x-6 and bc= 12-2x. Then what does ac equal?
ra1l [238]
Ab = (7x-6) →   b = (7x-6)/a   (1)

bc = (12-2x) → b = (12-2x)/c   (2)

Since (1) = (2) → (7x-6)/a = (12-2x)/c OR  a/c = (7x-6)/(12-2x)  (3)

Multiply  both numerators of (3) by the SQUARE of their  respective denominators;

(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:

ac = (7x-6)(12x-2x)  or ac = -14x² + 96x - 72
