Carpet costs $21.95 per square yard and the padding to put under it costs $2.55 per square yard. Felix plans to install padding and carpet in the region shown in the figure. What is the total cost of the carpet and padding needed to exactly cover the room?

Answers

Answer:

$1679.175 or $1679.18

Step-by-step explanation:

split the carpet into rectangles to make it easier to look at

one rectangle is 2 yards in height and 9 yards in width (5 yards plus 4 yards)

area of a rectangle = (w)(h), so 9 x 2 = 18 yards in area.

second triangle is 4 yards in width, and 3 yards in height.

area of a rectangle = (w)(h), so 4 x 3 = 12 yards in area.

Total area = 30 yards

30(21.95)(2.55) = $1679.175 or $1679.18

cross multiply

9x = 153,000

x = 153,000/9

x = 17,000

1 3/4 pounds of pancake mix. Jada used 7/8 pound for a recipe. What fraction of the pancake mix in the box did she use?

Answers

Answer:

7/8

Step-by-step explanation:

If you turn 1 3/4 back into a simplified fraction it is 7/4. But the denominators need to be the same, so multiply the bottom number 2 and the top number by 2. That gives you 14/8. If she used 7/8 of it, then you just do 14/8 - 7/8 which gives you 7/8.

25 + x^2 + 10x = 0

solve for x

Answers

Answer:

x= -5

Step-by-step explanation:

answer is -5

Simplifying
25 + x2 + 10x = 0

Reorder the terms:
25 + 10x + x2 = 0

Solving
25 + 10x + x2 = 0

Solving for variable 'x'.

Factor a trinomial.
(5 + x)(5 + x) = 0

Set the factor '(5 + x)' equal to zero and attempt to solve:

Simplifying
5 + x = 0

Solving
5 + x = 0

Move all terms containing x to the left, all other terms to the right.

Add '-5' to each side of the equation.
5 + -5 + x = 0 + -5

Combine like terms: 5 + -5 = 0
0 + x = 0 + -5
x = 0 + -5

Combine like terms: 0 + -5 = -5
x = -5

Answer:

BC= 70

Step-by-step explanation:

If AC is equal to 140 and B is the midpoint of the line, then that would mean the line would be split in half thus having measures BA and BC. Both of the measures would have half of the full length so that would mean that BA and BC equals 70 since 140/2= 70

the answer is 70 hope u have good day
