Step-by-step explanation:
If she got a 90% on her test, and the test was 40 questions long, we need to do a bit of division and multiplication.
We have to divide 40 by 100, as percentages are out of 100.
So now we have 0.4.
Now we multiply this by 90.
36. She got 36 answers correct out of 40, which means she got four wrong.

Answer:
Step-by-step explanation:
The dollar value of the 20% coupon will increase if the discount is from a larger amount. Applying the $25 coupon first reduces the amount that the 20% applies to, so reduces the dollar value of the 20% coupon.
Michelle used the 20% coupon first, so its value was 20%($100) = $20.
Natasha used the $25 coupon first, so the value of the 20% coupon was ...
20%($100 -25) = 20%(%75) = $15.
Michelle paid $20 -15 = $5 less.
Given that Sarah the cheetah ran 100 meters at a speed of 16.8 meters per second.
An olympian ran the 100-meter dash in 9.6 seconds.
Then speed of olympian = distance/ time = 100 meter/ 9.6 seconds = 100 meter/ 9.6 seconds = 10.4166666667 meter/ seconds
whis is approx 10.42 meter/seconds
Now we need to find about how much faster was Sarah the cheetah’s speed, to the nearest tenth of a meter per second.
16.8-10.42 = 6.38 = 6.4
Hence speed of Sarah the cheetah's is approx 6.4 meter per second more than the speed of olympian.
