Levart [38]

Answer:

The answer is 5 ft squared

Step-by-step explanation:

so you have the find the area of the circle first and you do that by starting with the formula which is

pi r2

the diameter is 2.45 so you divide that by to to get the radius and get 1.25

the you would multiply 1.25 times 1.25 times 3.14, and get 4.91 which rounds to by the nearest whole umber as 5 ft 2.

Anna11 [10]

Answer:

8.85% per year

Step-by-step explanation:

To find the interest rate of a compounding interest, we use the formula:

$r=n[(\dfrac{A}{P})^{\dfrac{1}{nt}}-1]$

Before we start solving, let's break down all the variables that we have.

A = 19,992.71

P = 10,000.00

n = 2

t = 8

r = ?

Now let's put the values into the formula.

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{2(8)}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{16}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{0.0625}-1]$

$r=2[(1.9992.1)^{0.0625}-1]$

$r=2[1.0442499885-1]$

$r=2[0.0442499885]$

$r=0.08849997699$ or $8.85%$

So the rate the Mrs. Emily Francis got from the bank was 8.85% per year.

Parker wants to ride his bicycle 34 miles this week. He has already ridden 10 miles. If he rides for 5 more days, how many miles

vazorg [7]

Answer: He rode 4.8 miles each day.

Variable: x = Constant distance distance traveledd each day.

Equation : 10+5x=34

Step-by-step explanation:

Total distance needs to travel = 34 miles

Distance already traveled = 10 miles

He will ride bicycle for 5 more days.

Let x = Constant distance distance traveledd each day.

Total distance = 10+5x

i.e.

$10+5x=34\\\\\Rightarrow\ 5x=24\\\\\Rightarrow\ x=4.8$

Hence, he rode 4.8 miles each day.
