1/2=2/4 1/4=2/8 1/12=2/24
Answer:
ZB = 54
Step-by-step explanation:
Complementary angles add to 90 degrees
ZA + ZB = 90
x-15 + x+3 = 90
Combine like terms
2x-12 =90
Add 12 to each side
2x-12+12 = 90+12
2x = 102
Divide by 2
2x/2 = 102/2
x = 51
We want to find the measure of ZB
ZB = x+3
ZB = 51+3
ZB = 54
Answer:28
Step-by-step explanation:
If she can invite only 45 and 17 are family just subtract 45 from 17 which is 28 she can Invite 28 more people
Answer:
14 minutes
Step-by-step explanation:
if Pete is x times fast then Repeat is 3x faster
so if both combine to complete a job in 56 minutes then we have
remember Pete is x hence Pete was 14 minutes fast
For P(t) = 920*1.06^(2t), the current population is 920, the percentage growth rate is 6% semiannually, and the population in 4 years will be 920*1.06^8 = 1466.
Selection B is appropriate.
_____
The 2 in the exponent means the growth factor 1.06 is applied twice for each increment of t, that is, twice in 1 year (semiannually).
