Answer:
the amount of water she drinks is x, the mileage is y:
<u> x y </u>
2 miles 5 oz
4 miles 10 oz
6 miles 15 oz
the ratios would be 4/10 and 6/15
Step-by-step explanation:
for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.
think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.
hopefully that helps and isn't too confusing! if you need other help, let me know! :)
0, 2, 8, 10
Cross out 0 and 10
Left with:
2,8
Add them
10
Divide by 2
5 is the median.
When two are left in the middle you find the mean or average of them. Basically add them together and divide by 2.
Answer:
3. 273
4. 168
5. 189.25
Step-by-step explanation:
3. Triangle= .5 x 17 x 6 = 21
Rectangle= 18 x 14 = 252
252 + 21 = 273
4. Big rectangle (shaded)= 11 x18= 198
Small rectangle (right)= 5x4=20
Smaller rectangle (left)= 2x5=10
BR - (SR+SMR)
198-30=168
5. radius=5
Area of the circle= 25(pi)
Semi-circle= 39.25(not exact)
Rectangle= 10 x15=150
Rectangle + Semi-circle
150+39.25=189.25
