Answer:
First blank: 46%; second blank: 54%
Step-by-step explanation:
There are a total of 92+110 = 202 people who exercise 3 times per week.
Out of these, 92 exercise outdoors; this gives us
92/202 = 0.455 ≈ 0.46 = 46%
110 of these exercise in a gym; this gives us
110/202 = 0.5446 ≈ 0.54 = 54%
b 375
Answer: a=3.74
first use 15 to solve for x and z. x=7.5 and z=12.99 or 13. Once you know x you can use that to solve for y and a. y=6.5 and x=7.5 and using pythagorean theorem you will find that a= the square root of 14 or 3.74.
1. 3, 12, 48, 192, 768 Ratio: x4
2. 8, 16, 32, 64, 128 Ratio: x2
3. 120, 60, 30, 15, 7.5 Ratio: ÷2
4. 5, 10, 20, 40, 80, 160 Ratio: x2
5. 1.3?, 4, 12, 36, 108, 324 Ratio: x3
Hope this helps!
I'm not sure about the first one on question 5 though.
