Step-by-step explanation:
The answer is A
Answer: Assuming the unit is dollars, the answer would be $5,010.
Explanation:
Step 1: 8000-300 is 7700.
Step 2: 7700-290 is 7410
Step 3: 7410-400 is 7010
Step 4: 7010-2000 is 5010
So, the answer is Anna has $5,010 dollars left after giving Jim $300, buying shoes for $290, a suit for $400 and spending $2,000 dollars on a new phone.
Answer:
4
Step-by-step explanation:
(9 x 2/3) x 2/3
9x 2 = 18
18/3 = 6
6 x 2 = 12
12/3 = 4
(9 x 2/3) x 2/3 = 4
Answer:
Option A. ![30\ pounds](https://tex.z-dn.net/?f=30%5C%20pounds)
Step-by-step explanation:
step 1
Find the volume of the sphere ( medicine ball)
The volume is equal to
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
we have
----> the radius is half the diameter
Convert inches to feet
Remember that
1 ft=12 in
![r=5\ in=5/12\ ft](https://tex.z-dn.net/?f=r%3D5%5C%20in%3D5%2F12%5C%20ft)
assume
![\pi=3.14](https://tex.z-dn.net/?f=%5Cpi%3D3.14)
substitute
![V=\frac{4}{3}(3.14)(5/12)^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%283.14%29%285%2F12%29%5E%7B3%7D)
![V=0.3029\ ft^{3}](https://tex.z-dn.net/?f=V%3D0.3029%5C%20ft%5E%7B3%7D)
step 2
Find the weight of the ball
Multiply the volume in cubic foot by 100
![0.3029*100=30.29\ pounds](https://tex.z-dn.net/?f=0.3029%2A100%3D30.29%5C%20pounds)
Round to the nearest pound
![30.29=30\ pounds](https://tex.z-dn.net/?f=30.29%3D30%5C%20pounds)
