The area of the triangle on the right side is
Area = base*height/2
Area = 12*5/2
Area = 60/2
Area = 30 square inches

Multiply the area of the triangular base by the depth or height of the prism 15
Volume = (area of base)*(depth)
Volume = 30*15
Volume = 450 cubic inches

Answer: Choice D

Hello!

Two of these figures could create a rectangular prism when combined. Therefore, we can multiply the base by the height and divide it by two.

15(12)=180 (Base
180(5)=900

Now we divide by 2.

900/2=450

Therefore, our answer is D) 450 in³

I hope this helps!

Write the equation y=4x+9 in standard form using integers.

rosijanka [135]

Answer:

$4x-y=-9$

Step-by-step explanation:

The standard form of an equation is when both variables, x & y, are on the same side of the equation with a number on the other side.

To transform this equation from slope-intercept form to standard form, just switch sides for the y and the 9 like follows.

$4x-y=-9$

I hope this helped you :D

TiliK225 [7]

GIVEN

The following values are given:

$\begin{gathered} \mu=10.3 \\ \sigma=3.8 \end{gathered}$

SOLUTION

The z-score for the x values 9 and 14 can be calculated using the formula:

$z=\frac{x-\mu}{\sigma}$

For x = 9:

$\begin{gathered} z=\frac{9-10.3}{3.8} \\ z=-0.34 \end{gathered}$

For x = 14:

$\begin{gathered} z=\frac{14-10.3}{3.8} \\ z=0.97 \end{gathered}$

The probability can be calculated as follows:

$P(9\le x\le14)=Pr(-0.34The region that represents the solution is shown below:Therefore, the probability is given to be:[tex]P(9\le x\le14)=0.4671$

The probability is 0.4671.
