A rectangular prism has a length of 5 cm, a width of 2 1/2 cm, and a expressions height of 1 1/2 cm. Which can be used to find t

Assoli18 [71]

To find the volume of a rectangular prism, we can use the formula [ V = l * w * h ]

V = 5 * 2 1/2 * 1 1/2

V = 12 1/2 * 1 1/2

V = 18 3/4cm³

Now that we know the volume, we can check each answer choice.

Option A:

5 ∙ 2 1/2 ∙ 1 1/2

12 1/2 * 1 1/2

18 3/4cm³

Option B:

12 1/2 ∙ 1 1/2

18 3/4cm³

Option C:

1 1/2(5 + 2 1/2)

1 1/2(7 1/2)

11 1/4cm³

Option D:

1/2(12 1/2 ∙ 1 1/2)

1/2(18 3/4)

9 3/8cm³

Therefore, the only correct options are A and B.

Best of Luck!

Calculate the volume of this regular solid.

IgorC [24]

Answer:

V= 42.41

Step-by-step explanation:

$V = \pi r^{2}\frac{h}{3}$

where r is the radius = 3 and h is the height = 4.5

$V= \pi$ × $3^{2}$ × $\frac{4.5}{3}$

V = 42.41

In 2009, there were 1570 bears in a wildlife refuge. In 2010, the population had increased to

natita [175]

Answer:

$8,101\ bears$

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

$y=a(b)^{x}$

where

x ----> is the number of years since 2009

y ----> is the population of bears

a ----> is the initial value

b ---> is the base

step 1

Find the value of a

For x=0 (year 2009)

y=1,570 bears

substitute

$1.570=a(b)^{0}$

$a=1.570\ bears$

$y=1.570(b)^{x}$

step 2

Find the value of b

For x=1 (year 2010)

y=1,884 bears

substitute

$1,884=1.570(b)^{1}$

$b=1,884/1.570$

$b=1.2$

The exponential function is equal to

$y=1.570(1.2)^{x}$

step 3

How many bears will there be in 2018?

2018-2009=9 years

For x=9 years

substitute in the equation

$y=1.570(1.2)^{9}$

$y=8,101\ bears$
