Answer:
5 1/3 yds
Step-by-step explanation:
2/3 yds of fabric per pillow
8 pillows
2/3* 8 = 16/3 yds of fabric
Changing from an improper fraction to a mixed number
3 goes into 16 5 times with 1 left over
5 1/3 yds
Answer:
13/20 lbs
Step-by-step explanation:
1/4 lbs screws + 2/5 lbs nails
We need to get a common denominator
That would be 20
1/4 *5/5 + 2/5 *4/4
5/20 + 8/20
13/20 lbs
Answer:
15
Step-by-step explanation:
According to propagation rule,
Therefore, option (B) is correct
Answer:
25
Step-by-step explanation:
Since AC is similar to CE, we can say that they have equal lengths. We are given CE, DE, and BC. To solve this, we can solve for the length of CE (equal to AC) and then subtract that from BC.
To solve for CE, we are given DE and CE. We know that DE is 1/2 of CE because D is the midpoint of CE. Therefore,
7x-1 = 1/2(10x+18)
expand
7x-1 = 5x + 9
add 1 to both sides to separate the 7x
7x = 5x + 10
subtract 5x from both sides to separate the x
2x = 10
divide both sides by 2 to separate the x
x=5
Therefore, DE = 7(5)-1 = 34 and CE = 10(5) + 18 = 68 = AC.
Using x=5, we know that BC = 9(5) -2 = 43
Therefore, AB = AC-BC = 68-43 = 25
30% = .3
.3(24.40a + 14.50c)
24.40 = cost of adult ticket
14.50 = cost of child ticket
a = # of adult tickets sold
c = # of child tickets sold
.3 * 24.40a + .3 * 14.50c
answer: 7.32a + 4.35c
