Kenna's bedroom is 12 feet long by 8 feet long. Her parents have agreed to buy new carpet for the entire bedroom.The carpet costs $15 per square meter. What will be the total cost of the new carpet? 1 foot = 0.305 meter

A. $439.20

B. $54.90

C. $133.96

D. $91.50

Answers

Answer 1

Answer:

C. $133.96

Step-by-step explanation:

Convert units:

12 · 0.305 = 3.66 m

8 · 0.305 = 2.44 m

Find the area of the room:

3.66 m · 2.44 m = 8.9304 m²

Find the cost:

8.9304 · 15 = 133.96

Answer 2
C. $133.96

12ft = 3.66 sq meters
8ft = 2.44 sq meters

3.66 x 2.44 = 8.9304

8.9304 x 15 = 133.956

Tim has X beads
Amy has 2 more beads than Tim
Sarah has 5 times as many beads as Amy
How many beads does Sarah have?

Answers

Answer:

5x + 10

Step-by-step explanation:

Amy has 2 more beads than Tim, x, so she has x + 2 beads.

Sarah has 5 times more beads than Amy, so 5(x + 2). Simplifying this, we get 5x + 10

Sarah has 5x + 10 beads

Tim x Amy x+2 Sarah 5(x+2)
So Sarah has 5(x+2) which simplified is 5x+10

4 out of 5 games is 80%:

So if we know, as a rule that "Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure

100% sure

connor found out that 60% of 40 is the same as 25% of the number n. what is the value of n?

Answers

Answer:

96

Step-by-step explanation:

Step 1: Multiply 60% by 40

40 x .60 = 24

24 is 60 percent of 40

Step 2: If 24 was 25% of n, then we have to divide 100 by 25 to see how much we have to multiply 24 by.

100 ÷ 25 = 4

Step 3: Multiply 4 by 24

4 x 24 = 96

The answer is 96 :)

Hope this helps :)
