224 cubes

Step-by-step explanation:

The volume of the cubes is 1/64. Because 1/4*1/4*1/4=1/64.

The volume of the prims is 14/4 because 7/4*2*1=14/4.

Take the 14/4 and divide it by 1/64.

Which equals 896/4 = 224

You are painting the walls and ceiling of a rectangular 20 x 30 ft room. The walls are 10 feet tall. You need two coats of paint
Mkey [24]

Answer:

$424

Step-by-step explanation:

Find area of all surfaces to be covered

20 x 30 = 600 ceiling

10 x 20 = 200 x 2 = 400 two walls

10 x 30 = 300 x = 600 other two walls

Assume no doors

total area is 1600 square feet

multiply by 2 because you are doing two coats

3200 total area to be covered

3200/400 = 8 gallons of paint x $53 = $424

If five times the successor of a number is added to an original number the sum is 83
Alexus [3.1K]

Answer:

Let the original number be x

Successor is defined as the number which comes immediately after a particular number.

also, the  successor of a whole number is the number obtained by adding 1 to that number.

Then, the successor of a number x is, x+1

As per the given condition :

we have;

5(x+1)+x =83

Using distributive property on LHS (i.e, a\cdot(b+c)=a\cdot b+a\cdot c )

Then, we have

5x+5+x=83

Combine like terms;

6x+5=83

Subtract 5 from both the sides we get;

6x+5-5=83-5

Simplify:

6x=78

Divide both side by 6,

\frac{6x}{6} =\frac{78}{6}

Simplify:

x =13

Therefore, the original number x is, 13
