35. It doesn’t specify what type of triangle but if it’s referring to a right triangle it would be 10 if the missing side is the hypotenuse.
If not then it can also be 6 or 8 if it’s an isosceles triangle. I seen a lot of your questions and they don’t seem to have a good clarification of what they mean exactly and I’m an honors pre cal student

Find the area of a circle with a circumference of <br> 18.84

Anton [14]

Answer:

9π OR 28.26

Step-by-step explanation:

The formula for circumference is C = 2πr.

Substitute circumference = 18.84 for C.

18.84 = 2πr

Work backwards to find the radius of your circle.

$\frac{18.84}{2(3.14)} =r$

r = 3

Now, use the formula for the area of a circle: A = π $r^2$ .

Substitute r = 3 into the equation:

A = π $3^2$ = 9π ≈ 28.26

Charlie needs a $275,000 mortgage and he'd like to pay it off in 30 years. He is considering two banks. Bank A: 3.5% with monthl

zubka84 [21]

Answer:

Difference in interest= $41,250

Step-by-step explanation:

To calculate the interest paid on each bank loan we use the following formula

Interest = Principal * Rate * Time

For Bank A

Interest = 275,000 * 0.035 * 30

Interest = $288,750

For Bank B

Interest = 275,000 * 0.04 * 30

Interest = $330,000

Therefore

Difference in interest= 330,000 - 288,750

Difference in interest= $41,250

Therefore if the mortgage is taken from Bank B he will pay an extra $41,250 on the loan.

The 0.5% difference in rates has a large impact over the 30 year term loan

Jessica and her sister have a combined age of 47. Jessica is 5 years older than her sister. How old is Jessica

maw [93]

Let the sister be x years old.
Then Jessica is x + 5 years old.
Their ages add to 47.

x + x + 5 = 47

2x + 5 = 47

2x = 42

x = 21

x + 5 = 26

Jessica is 26, and her sister is 21.

The number of defects in the first five cars to come through a new production line are 9, 7, 10, 4, and 6, respectively. If the

garri49 [273]

Answer:

D. I and III only

Step-by-step explanation:

Number of first fie defects are given as 9,7,10,4 and 6.

First we have to arrange the above data in ascending order which is 4,6,7,9,10

Now if we consider the defect in sixth car to be 3 then our data will look like: 3,4,6,7,9,10

So the mean of above data would be $\frac{3+4+6+7+9+10}{6}$ = 6.5

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = $\frac{6+7}{2}$ = 6.5

Hence mean and median number of defects are same if the sixth car has 3 defects.

Now if we consider the defect in sixth car to be 12 then our data will look like: 4,6,7,9,10,12

So the mean of above data would be $\frac{4+6+7+9+10+12}{6}$ = 8

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = $\frac{7+9}{2}$ = 8

Hence mean and median number of defects are same if the sixth car has 12 defects.

But Now if we consider the defect in sixth car to be 7 then our data will look like: 4,6,7,7,9,10

So the mean of above data would be $\frac{4+6+7+7+9+10}{6}$ = 7.167

and Median of the above data would be = $\frac{3^{rd} obs + 4^{th} obs}{2}$ = 7

Hence mean and median number of defects are not same if the sixth car has 7 defects.

Therefore option D is correct.
