**Trevor invested $ 4720**

<em><u>**Solution:**</u></em>

Given that, **Trevor earned $ 826 on account during 2.5%** annual interest for seven years

We can simple interest formula

<em><u>**The formula for simple interest is given as:**</u></em>

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

Here given that,

Principal = p = ?

rate of interest = r = 2.5 %

number of years = n = 7

**Simple interest earned = 826**

<em><u>**Substituting the values in above formula,**</u></em>

**Thus he invested $ 4720**

**Answer:**

x=6.5

**Step-by-step explanation:**

This question is on intersecting cords and segments that intersect outside the circle

Forming an equation for this relation;

6(x+6)= 5(5+10)

6x+36=5(15)

6x+36=75.............................collect like terms

6x=75-36

6x=39...........................divide both sides by 6

x=6.5

**Answer:**

5 miles

**Step-by-step explanation:**

This is because if you draw a line going west and label it as 4 miles, then draw another line going south and label it 3 miles, you form a right angle, right? So, the fastest way to go back would be taking a diagonal-like route back to the beginning. Does this shape look familiar to you? Right! It's a right triangle. And do the numbers 3, 4, and 5 sound familiar to you? Yup, it's a Pythagorean triplet. If the legs of a right triangle are 3 and 4, the hypotenuse is 5. Why am I saying this? Because, in the drawing you just did, the 4 miles west and 3 miles south were the legs, and the diagonal path back to the beginning is the hypotenuse. Get it now?
