Carter has a fruit stand. In the morning, he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left. Which solution represents how many bas of peaches, b, Carter will sell before he restocks?
Answers
Answer:
Carter will sell 17 bags of peaches before he restocks.
Step-by-step explanation:
Total pounds of peaches Carter have = [tex]25\frac{1}{2} = \frac{51}{2} = 25.5[/tex]
Weight of each bag = [tex]1\frac{1}{2} = \frac{3}{2} = 1.5[/tex] pound
Number of bag made = [tex]\frac{25.5}{1.5}[/tex] = 17
The number is fully divided , it means no of peaches left = 0 < 3
So,
Carter will sell 17 bags of peaches before he restocks.
The number of bas of peaches, b, Carter will sell before he restocks is 17.
Calculation of the number of peaches:Since he has 25 1/2 pounds of peaches. He sells bags of peaches that each weigh 1 1/2 pounds. He will restock when he has less than 3 pounds of peaches left.
So here
[tex]= 25.5 \div 1.5[/tex]
= 17

A roller coaster accelerated from rest to 55 m/s by the time it reached the first hill. The roller coaster took 15 seconds to climb to the top of the hill. What was the acceleration of the coaster?
Answers
Answer:
I believe the acceleration is 3.66666666667 m/s
Step-by-step explanation:
Acceleration formula: a = vf - vi / t
Initial velocity: 0 (I believe it was 0, as it wasn't moving in the beginning)
Final velocity: 55 m/s
Time: 15 s
Substituting values: 3.66666666667 = 55 - 0 / 15

Answers
Hope this helps! :)
Answer:
one 20 inch pizza
Step-by-step explanation:
radius of one 10 inch pizza is 10/2 = 5
so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]
there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]
however 20 inch pizza radius is 10
so
[tex]10^{2}[/tex]×[tex]\pi[/tex] = 100[tex]\pi[/tex]

To determine
Simplify the expression
Let us simplify the expression
