How much money did the fundraiser make?

Answers

Answer 1

Answer:

Answer:

There are 102 coins total:

34 Quarters

20 loonies

48 toonies

Step-by-step explanation:

Assuming money is counted in coins instead of value, it can be solved like this.

1. find a common denominator for 1/3 and 1/5. We can use 15. So, of the money collected, 5/15 were quarters and 3/15 were loonies. This makes 7/15 toonies. If there are 48 toonies, we can divide this by 7 to find the value of 1/15. 48/7 = 6 6/7. Multiply this number by 15 (for each value) and you get 102 6/7.

There are 102 coins total:

34 Quarters

20 loonies

48 toonies

What is the height of a triangular plate if its area is 1225 square centimeters and the length of its base is 35 centimeters, and how can you calculate this height using the formula for the area of a triangle?

Answers

Answer:

height = 70 cm

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = $(1)/(2)$ bh ( b is the base and h the height )

given b = 35 and A = 1225 , then

1225 = $(1)/(2)$ × 35 × h

1225 = 17.5h ( divide both sides by 17.5 )

$(1225)/(17.5)$ = $(17.5)/(17.5)$ h , that is

70 = h

then the height of the triangle is 70 cm

What is the ratio of people who prefer oranges to bananas?

Answers

I saw the pie chart that should have accompanied this word problem.

Favorite fruit:
Grapes = 150
Apple = 220
Orange = 185
Banana = 235

Choices:
A) 37/47
B) 185/790
C) 790/275
D) 235/185

Oranges = 185 ; Bananas = 235

Ratio of oranges to Bananas = 185/235
Simplify 185/235
185 ÷ 5 = 37
235 ÷ 5 = 47

Ratio of oranges to Bananas = 37/47 Choice A.
