I need help boi a(c – b) = d c =
alexandr1967 [171]

Hello from MrBillDoesMath!

Answer:

c = d/a + b


Discussion:

I think the Question is missing a comma.  Assuming you are trying to find the value "c",

a(c-b) = d  =>                               divide both side by "a"

(c-b) = d/a =>                               add "b" to both sides

c-b + b = d/a + b =>                      as -b + b = 0

c = d/a + b




Thank you,

MrB

Find the volume of this object.
Tems11 [23]

Answer:

408 cm^3

Step-by-step explanation:

You have to find the volume of each object individually. You first find the volume of the sphere, so you input the radius, which is 3, into the equation which comes out to be 108 cm^3. You then have to find the volume of the cylinder, and since you have the diameter of the cylinder, and you need the radius, and the radius is half of the diameter, you would input 5 into the equation as the radius, since half of 10 is 5. That comes out to be 300 cm^3, so then you add the two volumes together, which is 408 cm^3

Find the area of a parallelogram with sides of 6 and 12 and an angle of 60°.
Anna007 [38]

ANSWER

36√3 square units.

EXPLANATION

The area of a parallelogram is obtained by multiplying the base by the height.

We use the sine ratio to obtain the height.

\sin(60 \degree)  =  \frac{h}{6}

h = 6 \sin(60 \degree)

h = 3 \sqrt{3}

The area becomes:

12 \times 3 \sqrt{3}  = 36 \sqrt{3} {units}^{2}
