What is the volume of the composite figure below? (formula for volume of a prism is 1/3 Bh where B is the area of the base.)
arsen [322]

Answer:

Last Option; 84 cu. mm

Step-by-step explanation:

We know that;

Volume = 1/3(Bh)

And that this is figure has a square base, therefore B that represents the area of the base will be: 6 * 6 = 36

And height = 7mm

Therefore we can say;

Volume = (1/3)*(6 x 6)*(7)

Volume = (1/3)*(36)*(7)

Volume = (12)*(7)

<u>Volume = 84</u>

Hope this helps!

Mom put plums and apples onto a plate. The ratio of the number of plums to the number of apples was 3:2. How many fruit did mom
Delvig [45]

Answer:

30 fruits

Step-by-step explanation:

Let

x ----> number of plums on the plate

y ----> number of apples on the plate

we know that

The ratio of the number of plums to the number of apples was 3:2

so

\frac{x}{y} =\frac{3}{2}

x=1.5y ----> equation A

After Ed took 6 plums from the plate, the number of plums remaining on the plate became the same as the number of apples

so

x-6=y ----> equation B

substitute equation A in equation B

1.5y-6=y

solve for y

1.5y-y=6\\0.5y=6\\y=12

Find the value of x

x=1.5(12)=18

therefore

Mon put on the table

x+y=18+12=30\ fruits

Write the point-slope form of the equation of the line through the given point with the given
UNO [17]

Answer:

The point-slope form of the equation is:

  • y-\left(-5\right)=-3\left(x-3\right)

Step-by-step explanation:

Given

  • point (3, -5)
  • slope = -3

We know the point-slope form of the line equation is

y-y_1=m\left(x-x_1\right)

where m is the slope

substituting the values m = -3 and the point (3, -5)

y-y_1=m\left(x-x_1\right)

y-\left(-5\right)=-3\left(x-3\right)

Thus, the point-slope form of the equation is:

  • y-\left(-5\right)=-3\left(x-3\right)
