Answer: 82.93%
Step-by-step explanation:
write a proportion
68/82=x/100
(Why x/100, because in a test the highest you can get is a 100%)
cross multiply
6800=82x
( 68(100) = 82(x))
Isolate the variable
6800/82≈ 82.93 (rounded)
Answer:
3.4 pizzas
Step-by-step explanation:
Given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon
y represents number of pizzas sold and x number of coupons issued
y is marked verticaly and x horizontally
The trend line is given as
y =3.4x+43
This says that even when no coupon is issued pizzas sold will be 43
and rate of change of pizza sold for 1 unit of coupon = slope = 3.4
i.e. when x increases by 1 unit y increases by 3.4 units
Hence For each additional coupon issued 3.4 pizzas more will be sold
992,449 rounded to the nearest hundred thousands is 1,000,000.
Answer:
Joey completed 52 pushups each day.
Step-by-step explanation:
We know that he did 1,456 pushups in 4 weeks, and that there are 7 days a week. This means that he did those pushups in the span of 28 days. So, divide 1,456 by 28 to get 52 pushups.
x =15.
Step-by-step explanation:
100 - 6x = 160 - 10x
-6x = 160 - 10x - 100
-6x = 60 - 10x
4x = 60
x = 15
