Answer:
The correct option is C. 47.10 inches
Step-by-step explanation:
Diameter of the tire rim is given to be 15 inches
So, The radius of the tire rim will be 7.5 inches
Now, we need to find the circumference of the tire rim
And, The circumference of the tire rim is given by the formula :
Circumference = 2·π × radius
⇒ Circumference of the tire rim = 2 × 3.14 × 7.5
⇒ Circumference of the tire rim = 47.1 inches
Therefore, The correct option is C. 47.10 inches
The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82
Mixed number: 9 2/9
1. How many 9's go into 83
2. It is 9 because 9*9 = 81 9*10=90 is bigger so not possible
3. 2 is left because 83-81 = 2
4. And don't forget the denominator
In a typical 30-60-90 triangle (which happens to be a right triangle, by the way), the sides, in increasing order, would be multiples of 1, sqrt(3) and 2.
Here, sqrt(3) is the longer leg (it's longer than 1).
Thus, the ratio of the length of the longer leg to the length of the hypotenuse
is sqrt(3)
