These are false. Tami will need to work 11 weeks to get to her goal. To find out this problem, first take out the 100 from the 320 which then gives you 220. Then divide 220 by 20 which gives you 11. 1 is wrong because Tami does not have to work more than 21 weeks to get to her goal. 2 is also wrong because Tami does not need to save more that 11 weeks to get to her goal, she has to work 11 weeks only.
Answer:
2.871*10^9
Step-by-step explanation:
add a decimal point at the end of the number ( 2,871,000,000.) then count how many places it takes to move the decimal point between the first and second number (2.8) then write the rest of the numbers higher than "0" after, giving you the 2.871
to show that the number written is in scientific notation you add 10 to the power of the amount of times you moved the decimal place. In this case, because the decimal point was moved a total of 9 times, it would be 10 to the 9th power (10^9).
Answer:
12%
Step-by-step explanation:
Answer:
Option A. 
Step-by-step explanation:
step 1
Find the volume of the sphere ( medicine ball)
The volume is equal to

we have
----> the radius is half the diameter
Convert inches to feet
Remember that
1 ft=12 in

assume

substitute


step 2
Find the weight of the ball
Multiply the volume in cubic foot by 100

Round to the nearest pound

1: slope = 2/1 or 2
2: slope = 5/-5
3: slope = 3/2
4: slope = 7/-4
5: slope = 3/5
6: slope = 2/-8
7: slope = 6/2 or 3
8: slope = 2/-4
9: slope = 1/6
