Answer/Step-by-step explanation:

Volume = l*w*h

or in this case a*b*c

A*B = 5*2 = 10

Ab = 10

10* C = 10*7 = 70

ABC = 70^3 or 70 cubic units

<h2>Answer : C. 70 cubic units</h2>

The diameter of a circle measures 10 yd. What is the circumference of the circle?

crimeas [40]

Answer:

31.4 yards

Step-by-step explanation:

Radius (R) = d / 2

R = 10 / 2 = 5 yards

Circumference (C) = 2 π r

C = 2 * 3.14 * 5 yards

C = 31.4 yards

If f(x) = x ² +1 and g(x) =3x+ 1,find [f(4)] ²

guajiro [1.7K]

Answer:

289

Step-by-step explanation:

We don't need $g$ at all for this.

We will need to know $f(4)$ before continuing...

$f(4)$ can be found by replacing $x$ in $f(x)=x^2+1$ with $4$ :

$f(4)=4^2+1$

$f(4)=16+1$

$f(4)=17$

-------------------

Now let's find $[f(4)]^2$ :

$[f(4)]^2$

$[17]^2$

$17(17)$

$289$

Figure ABCD - Figure EFGH

Colt1911 [192]

<h3><u>Answer:</u></h3>

30.5 units

<h3><u>Step-by-step explanation:</u></h3>

We know that:

<u>Trapezoid ABCD has one side that is 25 unit. </u>
<u>The other 3 sides (AB, BC, and CD) are 12 units. </u>
<u>EF = 6 units</u>
<u>EH = 12.5</u>
<u>Trapezoid ABCD is congruent to Trapezoid EFGH</u>

<em>If the 3 sides of the trapezoid ABCD are the same sides, then side EF, FG, GH must be of the same length because of congruence. The value of FG and GH must be the same length as EF. We can clearly see in the picture that EF is 6 units. Hence, EF is 6 units, FG is 6 units, and GH is 6 units. The work of the perimeter is shown below.</em>

=> 6(3) + 12.5
=> 18 + 12.5
=> <u>30.5 units</u>

Hence, the perimeter of EFGH is 30.5 units.
