Answer: The basketball will sell for $21
.
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the cost of the basketball (10) by the percent markup in decimal form (divided by 100).
Mathematically speaking:
10 x (110/100) = $11
Now, we have to add the markup amount (11) to the cost (10) to obtain the selling price:
10 +11 = $21
The basketball will sell for $21

Because his friends are not representative. If he would want to receive information about his friends, then this would be a good sample, however, considering that Mason probably wants data that are more representative, it would be better for him to gather info from his school or even wider. This would help him get better data for what he wanted to find information about :)
Answer:
Step-by-step explanation:
1 inch = 42 miles
3.375 inches = 141.75

Answer:
The top speed of William's boat was 45 mph
Step-by-step explanation:
Let
x -----> represent the rate of the boat in still water in mph
we know that
The speed or rate is equal to divide the distance by the time
speed=distance /time
time=distance/speed
<em>Downstream</em>
speed=(30+x) mph
distance=10 mi
time1=10/(30+x)
<em>Upstream</em>
speed=(x-30) mph
distance=2 mi
time2=2/(x-30)
The sum of the time downstream plus the time upstream must be equal to 16 minutes
Convert minutes to hours


Multiply by (x+30)(x-30) both sides

Multiply by 60 both sides

Divide by 16 both sides

The solution is x=45\ mph
There you go :) hope this helps!
