For question 1 your answer will be 2.16

If it costs $2.40 for 1 lbs of granola, then to get the price for 0.1 lbs of granola we divide 2.40 by 10.

2.40 ÷ 10 =0.24

Now, we multiply 0.24 by 9 and that will be your answer

0.24 × 9 = 2.16

For Question 2 your answer is

False

4 ÷ 13 = 0.31

0.31 × 36 = 11.16

11.16 is more than 10

For question 3, your answer is 21

Since 14 is 1/2 of 28, to get the answer we just divide 42, by 2

42 ÷ 2 = 21

For question 4 your answer will be 726

She rides 12 miles in 132 minutes, which means if we divide the numbers by 2 we will get half the amount of time and half the distance

12 ÷ 2 = 6

132 ÷ 2 = 66

12 goes into 60, 5 times and since we found the time for 6 miles, we won't have to worry about the extra 6. We could also multiply 6 by 11.

6 × 11 = 66

OR

66 × 11 = 726

For question 6 your answer will be $147

He buys 4 tickets for 84, to get the cost of 1 ticket we divide 84 by 4

84 ÷ 4 = 21

Now, to get the cost for 7 tickets we multiply 21 by 7

21 × 7 = 147

For question 7 your answer will be

Cookies Pastries

3 2

6 4

12 8

This is your answer because in the second pair, it shows double the first racio and in the third it shows triple.

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,
