1. What is the volume of the prism that can be constructed from this net?
Irina-Kira [14]
1. V = lwh
    V = (8)(4)(5)
    V = (32)(5)
    V = 160 units³

2. V = lwh + lwh
    V = (4)(2)(1) + (3)(1)(1)
    V = (8)(1) + (3)(1)
    V = 8 + 3
    V = 11 units³

3. V = leh + s³
    V = (9)(3)(4) + (3)³
    V = (27)(4) + 27
    V = 108 + 27
    V = 135 units³

4. V = lwh
    V = (3)(7)(2)
    V = (21)(2)
    V = 42 units³

34. Samir can rent a moving truck from
nadezda [96]

The true statement is that renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

<h3>What is a linear equation?</h3>

The linear equation is given as,

y = mx + c

Where m = the slope of the line

c is the y-intercept of the line.

Let y be the total amount and x be the number of miles.

Samir can rent a moving truck from Company A for $35 plus $0.50 per mile. Then the equation will be

y = 0.5x + 35   ....1

Company B for $25 plus $0.70 per mile. then the equation will be

y = 0.7x + 25     ....2

For the same rent, the number of miles will be

0.7x + 25 = 0.5x + 35

0.2x = 10

x = 50 miles

Renting from Company B will be cheaper if Samir drives the truck 100 miles. Then the correct option is D.

BRAINLIEST AND POINTS!!!<br><br> PLEASE EXPLAIN
timofeeve [1]

Answer:

Option C. \$23,134.61

Step-by-step explanation:

we know that

A=\frac{P[(1+r)^{n} -1]}{r(1+r)^{n}}

we have

P=\$400

r=0.075/12=0.00625

n=6*12=72\ months

substitute in the formula

A=\frac{400[(1+0.00625)^{72} -1]}{0.00625(1+0.00625)^{72}}\\ \\A=\frac{226.446972}{0.009788}\\ \\A=\$23,134.61
