Half of Sarah's wire is equal to ⅖ of Daniel's. Chris has 3 times as much as Sarah. In all, their wire measures 6 ft. How long is Sarah's wire in feet?
9514 1404 393
Answer:
1 1/7 ft
Step-by-step explanation:
Let s, d, c represent the numbers of feet of wire held by Sarah, Daniel, and Chris, respectively.
1/2s = 2/5d . . . . . . half of Sarah's is 2/5 of Daniel's
c = 3s . . . . . . . . . . .Chris has 3 times as much as Sarah
s + d + c = 6 . . . . . in all, they have 6 feet
Multiplying the first equation by 5/2, we find ...
d = 5/4s
Substituting for d and c in the last equation gives ...
s + 5/4s +3s = 6
s(21/4) = 6
s = 6(4/21) = 24/21 = 8/7
Sarah's wire is 1 1/7 feet long.
Select the correct answer. Which number has a repeating decimal form? A. 15 B. 11/25 C. 3/20 D. 2/6
Answer:
its D 2/6
Step-by-step explanation:
From the given options 2/6 has a repeating decimal form. Therefore, option D is the correct answer.
From the given options we need to find which number has a repeating decimal form.
What is a repeating decimal form?A repeating decimal or recurring decimal is the decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero.
Now, from option A:
1/5=0.2
From option B:
11/25=0.44
From option C:
3/20=0.15
From option D:

38.5g of sugar is needed to make 5 cakes. How much sugar is needed for 7 cakes?
Answer: 53.9g
Step-by-step explanation:
As you can't end up with a whole number by doing 7 divided by 5, first work out how much sugar is needed for 1 cake.
To find out how much sugar is needed for 1 cake, divide both sides by 5:
5 / 5 = 1
38.5 / 5 = 7.7
Therefore 7.7g of sugar is needed to make 1 cake.
Now times each value by 7 to get the answer :
7.7 x 7 = 53.9g
1 x 7 = 7
Therefore, 53.9g of sugar is needed.
Answer:
53.9g
Step-by-step explanation:
38.5 / 5 as there are 5 cakes
this will give you the amount of sugar needed for 1 cake, so you X by 7 to find out how many for 7 cakes
38.5 / 5 = 7.7
7.7 X 7 = 53.9g
Micah is buying items for a party. There are 6 cups in a package and 8 plates in a package.If he wants to have the same amount of each item, what is the least number of packages of cups he needs to buy
Answer: 24
Step-by-step explanation:
From the question, we are informed that Micah is buying items for a party and that there are 6 cups in a package and 8 plates in a package.
We are further told that he wants to have the same amount of each item. The least number of packages of cups he needs to buy would be calculated by finding the least common multiple of 6 and 8.
Multiples of 6 = 6, 12 18, 24, 30
Multiples of 8 = 8, 16, 24, 32, 40
The answer is 24 cups
