In a mixture of raisins and peanuts, 30% of the mixture is raisins and there 56 peanuts; how many raisins are in the mixture?
Answer: 24 raisins
Step-by-step explanation:
30% of the mixture are raisins which means that 70% are peanuts.
That 70% translates to 56 peanuts.
The total of the mixture is therefore:
= 56 / 70%
= 80 mixture of raisins and peanuts
Raisins are 30%:
= 30% * 80
= 24 raisins

2.The Briarwood Middle School chess club has 55 members. 22 of the members are in seventh grade.
To convert a fraction into a percent divide the numerator by the denominator and then multiply that result with 100. We can show this formula by (Numerator/Denominator)*100.
(22/55)*100
= 40.00%
= 40%

5. Vernon drew an 8 in, wide by 5 in. tall picture that will be turned into a
48 ft wide billboard. How tall will the billboard be?
ACTICE ORIEM SOLVING
Answer:
The billboard should be 30 feet tall
Step-by-step explanation:
Height of the picture = 5 inches
Width of the picture = 8 inches
But the billboard has a width of 48 feet = 12 x 48
= 576 inches
To know how tall the billboard is, we have to determine the scale factor required.
scale = [tex]\frac{width of billboard}{width of picture}[/tex]
scale = [tex]\frac{576}{8}[/tex]
= 72
scale = 72
The height of the billboard = scale x 5 inches
= 72 x 5 inches
= 360 inches
Also,
The height of the billboard = [tex]\frac{360}{12}[/tex]
= 30 feet
Therefore, the billboard would be 30 feet tall.

Sandy's dad just finished working and was paid $8000 for his work. Her dad gave her mom 5/8 of his salary to pay for household expenses. Her mom gave her brother 1/15 of the amount she received as allowances for her brother. Her brother gave Sandy 2/3 of his allowances because he owed her money. How much money did Sandy get from her brother?
a) Write an equation for this scenario
b) Solve the scenario and find out how much money Sandy got from her brother
Answer:
Sandy got (approximately) $222.22 from her brother.
Step-by-step explanation:
5/8 (8000) = 5000
1/15 (5000) = 333.33
2/3(333.33) = 222.22
