Answer:
2\10
Step-by-step explanation:
1\2 = 5\10
7\10 - 2\10 = 5\10
Time = distance / speed
time = 621 / 51.75
time = 12 hrs <====
It is called effective interest rate.
For example, you invest in a bond wich pays 5% annual interest rate and it compounds semiannually.
The first semester you win 2.5% over the capital invested and in the second semester you win 2.5% over the capital plus the interested earned in the first semester. Then the effecive interest rate is higher than 5%.
Answer:
4/5x(v-7)=2
multiply both sides by 5/4, the reciprocal of 4/5
v-7=2x(5/4)
Express 2x(5/4) as a single fraction
v-7=<u>2</u><u>x</u><u>5</u>
4
Multiply 2 and 5
v-7=<u>1</u><u>0</u>
4
Reduce the fraction 10/4 to the lowest by extracting and cancelling 2
v-7=<u>5</u>
2
Add 7 to both sides
v=<u>5</u>+7
2
Covert fraction to 14/2
v=5/2+14/2
Since 5/2 and 14/2 have the same denominator, add them by adding their numerators
v=<u>5</u><u>+</u><u>1</u><u>4</u>
2
Add 5 and 14 together
v=<u>1</u><u>9</u>

Answer:
Actual width = 5 feet.
Step-by-step explanation:
The ratio of 1.2 to 1 equals the ratio of length to width.
1.2 / 1 = 6 / w where w is the actual width.
1.2w = 6
w = 6/1.2
w = 5.
