Answer:
1
Step-by-step explanation:
5/9 = 0.5555555
The smallest sequence of repeating digits in the decimal equivalent of 5/9
0.5
0.5 + 0.05
0.5 + 0.05 + 0.005
0.5 + 0.05 + 0.005 + 0.0005
Hence, the number of digit in the smallest sequence of repeating decimal is 1
5/9 = 0.5....
1/2 - y (6y - 8)
1/2 -6y2 - 8y
the answer is A
Answer:
121 smokers
Step-by-step explanation:
This can be calculated as a simple rule of 3.
In these problems, the first step is identifying the measures in the problem. Then, we must identify whether their relation is direct or inverse.
When it is direct, as one measure increases, the other will increase too.
When it is inverse, as one measure increases, the other will decrease.
In this problem, the measures are the number of people over 12 that smoke, and the total number of people over 12. Their relation is direct, because as the number of people increases, the number of smokers will increase too.
So we must solve the following rule of three:
22 smokers - 100 people
x smokers - 550 people
x = 550*22/100
x = 22*5.5
x = 121 smokers.
So, in a group off 550 people over the age of 12, there are 121 expected smokers.
0.02 times 0.7 = 0.014 all u needed to do was 2 times 7 and add two zeros
Okay so.
We have two basic equations
Tower A+ B+720 A is 720ft taller than B.
Tower A+B= 1982 Combined height is 1982ft
Replace A with B+720 in 2nd equation and solve for B
B+720+B=1982 Combine like terms
2B+720=1982 Subtract 720 from both sides
2B=1262 Divide both sides by 2
B=1262/2
B= 631ft
We know that A=B+720 so you simply need to do that addition to have the height of both towers.
