Answer:

The ladder is the hypotenuse and one side equals 5 feet.

From the Pythagorean Theorem we can calculate the other side:

other side^2 = 12^2 -5^2

other side^2 = 144 -25

other side^2 = 119

other side = 10.9087121146

Rounding, we get 11 feet.

What is the volume of a rectangular prism with a length of 1. 4 meters, a width of 0. 5 meter, and a height of 1. 8 meters? 7. 5
mihalych1998 [28]

The volume of the rectangular prism will be  V=1.26m^{3}

<h3>What will be the volume of the rectangular prism ?</h3>

Given that

\rm Lenth \ of \ the \ rectangular \ prism =1.4\ m

\rm width\ of \ prism=0.5\ m

\rm Height \ of \ prism=1.8\ m

\rm Volume \ of \ the \ Rectangular \ Prism= L\times W\times H

V=1.4\times 0.5\times1.8=1.26 \ m^{3}

Thus the volume of the rectangular prism will be  V=1.26m^{3}

To know more about the volume of the rectangular prism follow

Triangle X Y Z is shown. The length of side X Y is (9 n + 12) feet and the length of side X Z is (15 n minus 6) feet. Angles X Y
zmey [24]

Answer:

n = 3

XY = 39

XZ = 39

Step-by-step explanation:

Given

XY = 9n + 12

XZ = 15n - 6

Solving (a): n

To solve for n;

We make use of

XY = XZ

Substitute values for XY and XZ

9n + 12 = 15n - 6

9n - 15n = -12 - 6

-6n = -18

Divide through by -6

n = 3

Solving (b) XY

XY = 9n + 12

Substitute 3 for n

XY = 9 * 3 + 12

XY = 27 + 12

XY = 39

Solving (c): XZ

XZ = XY

XZ = 39
