B because each input has one output
Answer:
11 1/2
Step-by-step explanation:
1. a
2. 6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.
3. 12/8 = 1.5 seedling per minute in 70 minutes...
1.5 * 70 = 105 seedlings can be planted in 70 minutes
4. idk sorry
5. time = distance / speed
time = 300/15
time = 20 hrs
7. The ratio between 12 and 8 is 1.5, so you need to divide every other number by 1.5.
2/1.5=1.3
9/1.5=6
18/1.5=12
8. So, problem statement tells you that 1lb = 16oz and that 1oz = 28.3g. That means that 1lb = 16 * 28.3g = 452.8g
You have three items, convert their weights to grams:
1) 800g
2) 1.6lb = 1.6 * 452.8g = 724.48g
3) 30oz = 30 * 28.3g = 849g
So, sorting from greatest:
3, 2, 1, or: 30oz, 1.6lb, 800g.
9. 5•7=30
10.it will clean 7 cars in 56 minutes
hope this helps and i hope its not confusing
Answer:
Step-by-step explanation:
For the quadratic equation 
the discriminant is defined as
and the quadratic formula for the roots gives us two roots:
and
For the equation 
use quadratic formula to find roots:
So,
Vsphere=(4/3)pir³
d/2=r
given
d=4
d/2=r=4/2=2
Vsphere=(4/3)pi2³
Vsphere=(4/3)pi8
Vsphere=32/3pi
using pi=3.14
Vsphere=33.493333333333 cm³
round
Vsphere=33 cm³
