The appropriate choice is ...
(25−2x)(20−2x)x

_____
When x is cut from each side of the 25 dimension, the remaining dimension of the bottom of the box is 25-2x. Similarly, when x is cut from each side of the 20 dimension, the remaining dimension of the bottom of the box is 20-2x. The length of the side that is folded up is x, so that is how deep the box is.

The volume is the product of the dimensions of the bottom and the side:
(25−2x)(20−2x)x

Answer:

3/8 sq. units

Step-by-step explanation:

The formula for area for a trapezoid is

Area = (1/2)*(base1+base2)*height

Area = (1/2)*(1/2 + 1/4) * 1

Area = (1/2)*(2/4 + 1/4)

Area = (1/2)*(3/4)

Area = 3/8 sq. units

7. What is the volume of the prism? 8 cm 5.8 cm A. 29 cm B. 87 cm3 15.2 cm C. 512.3 cm3 D. 705.3 cm

bija089 [108]

The volume of the rectangular prism is

$V=L\times W\times H$

Where:

L is its length

W is its width

H is its height

From the given figure

L = 15.2 cm

W = 8 cm

H = 5.8 cm

Substitute them in the rule above

$\begin{gathered} V=15.2\times8\times5.8 \\ V=705.28\operatorname{cm}^3 \end{gathered}$

Round it to the nearest tenth

$V=705.3\operatorname{cm}^3$

andrezito [222]

Answer:

probability that Marnie and Noomi are both selected=0.1

Step-by-step explanation:

A group of 5 managers (Joon, Kendra, Lee, Marnie and Noomi), 2 people are randomly selected to attend a conference in Las Vegas.

the possibility of selecting 2 from 5 manages is 5C2 ways

$5C2= \frac{5!}{2!(5-2)!} =10$

There is only one choice of selecting Marine and Noomi from 5 managers

So probability of selecting Marine and Noomi is

$\frac{1}{10} =0.1$
