A fruit bowl is shaped like half of a sphere. The radius of the bowl is 15cm. what is the volume of the bowl
Naya [18.7K]

Answer: 7065 cm

Step-by-step explanation:

Find the volume as the bowl was a whole sphere and then divide the volume found by two, to get the volume of half the sphere.

(4/3) * π*(r^3) ≈ 14130 cm

14130/2 ≈ 7065 cm

This is an approximated result using π = 3.14

A team is selling pop corn for a fundraiser. The first week, they sell 500 bags. The second week, they sell 50% more than the fi
Dmitriy789 [7]

Answer:

The percentage decrease from the first week to the third week is 25 %

Step-by-step explanation:

The number of popcorn bags sold on the first week = 500 bags

The second week, they sell 50% more than the first week

So, the number of bags sold on the second week is

= 500 + 50% of 500

=500 +  \frac{50}{100}  \times 500

= 500 + 0.5 \times 500

= 500 + 250

= 750 bags

The third week, they sold 50% less than the second week

So, the number of bags sold on the third week is

=  750 - 50% of 750

= 750 - \frac{50}{100} \times 750

= 750 -0.5 \times 750

= 750 - 375

= 375 bags

Now the percentage decrease from the first week to the third week is

=\frac{500 - 375}{500} \times 100

= \frac{125}{500} \times 100

= 0.25  \times 100

= 25 %

PLEASE HELP ME
ElenaW [278]

Answer:

Step-by-step explanation: One number is four more than the other."   is represented as 'x'

"One number is four more than the other."  is represented as 'x+4'

"Their sum is fourteen."  is represented as 'x+(x+4)=14'

"Find both numbers."

x+(x+4)=14

x+x+4=14  (add like terms)

2x+4=14 (isolate your 'x' variable on one side of the equality by subtracting 4 from both sides)

2x+4-4=14-4

2x=10 (isolate your 'x' variable by dividing by 2 from both sides)

2x/2=10/2

x=5  (this is the answer to one number)

x+4=5+4=9 (plug in 5 for 'x' and this is the answer to four more than another)

Your two numbers are 5 and 9.
