The base of a rectangular prism has an area of 24 square millimeters. The volume of the prism is 144 cubic millimeters. The shap

Sav [38]

Answer:

height = 6 mm

Step-by-step explanation:

The prism is a rectangular prism. The base area of the prism is 24 mm². The volume of the prism is given as 144 mm³.

The height of the prism can be solved as follows.

Volume of the rectangular prism = Bh

where

B = base area

h = height

Volume = 144 mm³

B = 24 mm²

volume = Bh

144 = 24 × h

144 = 24h

divide both sides by 24

h = 144/24

h = 6 mm

How do I solve 3|x+10|=6

lianna [129]

Answer:

x=-8 x=-12

Step-by-step explanation:

Divide 3 to both sides

|x+10|=2

Set x+10 to equal 2 and -2

x+10=2 x+10=-2

solve both equations

x=-8/-12

21 = − 6 x − 3 x + 4 + 4 x

horsena [70]

Answer:

x=-17/5

Step-by-step explanation:

1. Simplify -6x-3x+4+4x−6x−3x+4+4x to -5x+4−5x+4.

21=−5x+4

2. Subtract 44 from both sides.

21−4=−5x

3. Simplify 21-4 to 17.

17=-5x

4. Divided both sides by -5.

-17/5=x

5. Switch sides.

x=-17/5

Hope this helps.

Intrigued by a 2013 study at the University of Nebraska that suggested marijuana smokers may be thinner than other adults, a gro

Reptile [31]

this question is incomplete, the complete question is:

1. is this model effective

2. what is the correlation coefficient for this data.

3. for a student with a bmi of 25, what is the predicted number of hours under the influence.

Step-by-step explanation:

1. first of all this model is not effective because we have r² as 0.134. this tells us that only 13.4 percent of the of the variations that exist in this data has been explained by the model

1. we get the correlation coefficient by

$+-\sqrt{r^{2} }$

the regression slope coefficient has a negative sign. this is what we would use in calculating the correlation coefficient.

$-\sqrt{r^{2} }$

= -√0.134

= -0.366

therefore the correlation coefficient is -0.366

2. to get the number of hours under the influence with a bmi of 25

the equation is

49.2-1.15bmi

= 49.2-1.15(25)

= 49.2-28.75

= 20.45
