Answer:

420

Step-by-step explanation:

300+40% equals 420 so he earned 420 last month from the commission

Answer:

$120

Step-by-step explanation:

A 40% commission means he earns 40% of the total revenue. That's 40% of $300 in this case.

To convert from a percentage to a multiplier, divide by 100:

[tex]\frac{40}{100} =0.4[/tex]

Then multiply the total revenue by that number:

[tex]300*0.4=120[/tex]

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can use the formula for the area of a kite, which is:

A = (1/2) x d1 x d2

where d1 and d2 are the lengths of the two diagonals.

In this case,

d1 = 2 feet, and d2 = 3 feet.

Substituting these values into the formula, we get:

A = (1/2) x 2 feet x 3 feet

   = 3 square feet

Therefore,

Marco will need 3 square feet of material to make the kite.

Answers

Answer:

1/8 Pounds
