Answer:

The number is 4.

Step-by-step explanation:

Let the number be = x

Five times the difference of twice a number and three can be written as 5(2x-3)

Decreased by the sum of the number and eight, (x+8)

Hence complete expression becomes:

5(2x-3)-(x +8)=13

Now solving for x;

=> 10x -15- x -8 =13

=> 9x- 23=13

=> 9x= 36

So we get x = 4

The number is 4.

Sierra applies a coat of epoxy paint to the four sides and floor of a rectangular swimming pool. The pool is 4 feet deep, 18 fee
Brilliant_brown [7]

Answer:

4 gallons of paint

Step-by-step explanation:

We solve using the formula for surface area of rectangular prism.

A=2(wl+hl+hw)

Where:

w = Width

h = Height

l = Length

The pool is 4 feet deep, 18 feet long, and 12 feet wide.

Hence,

=2 × (12 × 18 + 4 × 18 + 4 ×12)

=672 square feet

One gallon of paint covers 155 square feet.

Hence,

155 square feet = 1 gallon of paint

672 square feet = x

Cross Multiply

155 square feet × x = 672 square feet × 1 gallon of paint

x = 672 square feet × 1 gallon of paint/ 155 square feet

x = 4.335483871 gallons of paint

Therefore, based on the calculation above, approximately to the nearest whole number, Sierra uses 4 gallons of paint

3. How many 4-letter code can be formed using the first 10 letters of the English alphabet, if no letter can be repeated?
galben [10]

There cannot be more than two because there are only two vowels, e and a. But it has to be 4 lettered, which limits a lot of option, so there can only be one 4-letter code.
