Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

x=3\sqrt{15} meters or 11.62 meters

The right rectangular prism is made up of 48 cubes. Each cube has an edge length of inch. What is the volume of this prism?
Gnesinka [82]

Given:

  • The right rectangular prism is made up of 48 cubes.
  • Each cube has an edge length of 1/4 inch.

~

To Find:

  • What is the volume of this prism?

~

Solution:

~

<u>Using formula: </u>

~

  • \sf \pmb {Volume  \: of \:  cube =  {(side)}^{3} }

~

Substituting values in the formula:

~

\sf \longrightarrow  \dfrac{1}{4}  \times  \dfrac{1}{4}  \times  \dfrac{1}{4}

\sf \longrightarrow \dfrac{1}{64}  \:  {inch}^{3}

~

Now,

Volume of 48 such cubes = Volume of 1 cube × 48 cubes

~

\sf \longrightarrow \dfrac{1}{64}  \times 48

\sf \longrightarrow \dfrac{48}{64}

\sf \longrightarrow \dfrac{3}{4}  \:  {inch}^{3}

~

Hence,

  • Volume of prism is <u>3/4 inch^3</u>

Answer:

3.v-4=6

v=6+4

v=10

6.y-32=-1

y=-1+32

y=31

9.-1=t+(-19)

-1=t-19

-1+19=t

18=t

12.u+(-5)=-15

u-5=-15

u=-15+5

u=-10

15.47=w-(-8)

47=w+8

47-8=w

39=w

21.18f=-216

f=-216/18

f=-12

24.96=-24a

96/-24=a

-4=a

27.-84=d/3

-84*3=d

-252=d

30.81=1/6*n

81=n/6

81*6=n

486=n

33.5/9*p=-10

5p=-10*9

p=-90/5

p=-18
