Reiko works at kroger store near his house. every day he earns a flat rate of $10 plus $5 per hour. write a function rule. how much would reiko earn if he works 2 days of 5 hours/day?

Reiko makes $10 no matter what, and $5 per hour

let hour = h

let total = r

Equation:

r = 5h + 10

Reiko works 2 days of 5 hours. First solve the first day

r = 5(5) + 10

r = 25 + 10

r = 35

Reiko makes $35 in all in one day.

Multiply $35 twice to get the amount for two days.

$35 x 2 = $70

$70 is the amount Reiko makes

hope this helps

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
