Answer:
f = 1
Step-by-step explanation:
Use the method of cross- multiplication
= 
⇒ ad = bc, thus
20f = 5(f + 3) ← distribute
20f = 5f + 15 ( subtract 5f from both sides )
15f = 15 ( divide both sides by 15 )
f = 1
The batch of fruit salad has an equal amount of apples and cherries. This is because there are 1 1/2 c of apples and 1 2/4 c of cherries. the 1 1/2 is already simplified but the 1 2/4 is not. 1 2/4 is the same as 1 1/2, therefore apples and cherries have equal amounts.
Answer:
5 rolls of ribbon are needed
Step-by-step explanation:
To find how much ribbon you'll use, multiply 80 by 2 3/4. To multiply them, convert 2 3/4 into an improper fraction 11/4.
Multiply: 80 * 11/4 = 880/4 = 220
This means you need 220 total feet of ribbon. Since each roll has 50 feet, you'll need 5 rolls or 250 feet to wrap every box.
Answer:
the sum invested in Fund b is $6000
Step-by-step explanation:
This question can be easily solved using allegation Method.
Profit on fund A is 6% whereas Profit on fund B is 2%.
Fund A + Fund B= $24000
Overall profit to be gained = 5%
6% 2%
5%
3 : 1
therefore the fund was distributed in the ratio 3:1
⇒4 units= 24000
⇒ 1 unit = $6000
therefore the fund A = 3×6000=$ 18000
and the fund B= 1×6000= $6000
