Answer:
YES
Step-by-step explanation:
-3 times -4 = 12
12 + 2 = 14
14 < 15
Answer:
1/28 of the sack
Step-by-step explanation:
Unknown = x
the quotient of x and 12 is x/12 than 49 more than that is 53,
(x/12)+49=53, now use basic math and solve
-49 from both side,
x/12=4
*12 to both side,
x=48
therefore the unknown number is 48
Answer:
150
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
<1 + <2 = <3
3x+11 + 3x+19 = 7x+10
Combine like terms
6x+30 = 7x+10
Subtract 6x from each side
6x -6x+30 = 7x-6x+10
30 = x+10
Subtract 10 from each side
30-10 = x+10-10
20 =x
We need to find angle 3
<3 = 7x+10
= 7(20)+10
= 140+10
= 150
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)
