Answer:
number of gym members who prefer bicycling : 18/75*350 = 84
number of gym members who prefer exercise classes: 22/75*350 ≈ 103
number of gym members who prefer running on the treadmill: 15/75*350 = 70
number of gym members who prefer weight lifting: 20/75*350 ≈ 93
Step-by-step explanation:
GYM SURVEY RESULTS
Type Number of Members
Bicycling 18
Exercise Classes 22
Running on Treadmill 15
Weight Lifting 20
Total 75
Answer:
w = 24
Step-by-step explanation:
= 15
Multiply both sides by 8.
5w = 15 × 8
= 120
Find w.
w = 120 ÷ 5
w = 24
Answer:
y=5
Step-by-step explanation:
esa es la respuesta
Answer:
1 quart blue + 1 1/2 quart red
Given:
Ratio of blue paint : red paint = 1/3 : 1/2
simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:
(1/3) x (3x2) : (1/2) x (3x2)
2 : 3
From this we can determine the fractions of red and blue paint used in any total purple mix
fraction of blue paint = 2/(2+3) = 2/5 of purple mix
fraction of red paint = 3/(2+3) = 3/5 of purple mix
we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint
hence
amount of blue paint
= fraction of blue paint in purple mix x total amount of purple paint
= (2/5) x (5/2) = 1 quart
amount of red paint
= fraction of redpaint in purple mix x total amount of purple paint
= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart
