Answer:

this is quite easy. if the tire is 14 ft. tall, that would mean the diameter is 14 ft. as well (do to a tire being round). the radius is half of the diameter, meaning the radius is 7 ft. finally, to find the circumference, you would have to multiply pi by 2 (6.28) then multiply this by the radius to make 43.98 ft.

Step-by-step explanation:

D = 14

R = 14/2 = 7

C = 2(pi) x 7 = 6.28 x 7 = 43.98

10% of what number is 78?

Zepler [3.9K]

Answer: x = 780

Step-by-step explanation: Well percent means over 100 so we can set up an equation for this problem by reading it from left to right.

So we know that 10% means 10/100, of means times, what number means x, is means equals, and 12 means 12.

Notice that 10/100 can be reduced to 1/10.

So rewriting our problem we have X/10 = 78.

To get rid of the fraction, we multiply both sides of the equation by 10 and we have x = 780. So, 10% of 780 is 78.

Now let's check our answer back in the original problem to see if it makes sense.

We have 10% of 780 is 78. Well we know that 100% of of 780 would be 780 so 10% of 780 should be alot less than 780 so 78 seems to make sense.

The patio length on the side is the same as the garden, which is a square shape. Squares has the same side length on each side. 14x14=196. If you subtract 28 from 32, you have 4. Divide that by 2 and you have 2. 14x2=28. Add 196 and 28 together, and you will have 224.

Mr.Anderson paid $19.18 for a CD cover. This amount includes a tax of 8.5%. What was the cost of the CD cover before tax ?

MrRa [10]

X * 1.085 = 19.18
solve for x

Why is this how you figure it out? well... you have the price of the CD cover and the total is the price of the CD cover with tax.

Price of the CD cover would be: x * 1 = price of cd cover
Put that tax on there: x * 1.085 = price of cd cover with tax

why .085? move that decimal over two places to the left from the 8.5%

A person places $82100 in an investment account earning an annual rate of 4.3%, compounded continuously. Using the formula V = P

SVETLANKA909090 [29]

Answer:

$89,472.58

Step-by-step explanation:

P = $82100

r = 4.3% = 4.3/100 = 0.043

T = 2 years

V = P × e^rt

V = 82100 × e^(0.043 × 2)

V = 82100 × e^(0.086)

V = 82100 × 1.0898

V = 89,472.58

The interest after 2 years is $89,472.58
