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:
69.6 miles per hour
Step-by-step explanation:
Length of the skid marks = 242 feet
The formula used for the velocity is

where, L is the length of skid marks in feet and the velocity obtain has the units of miles per hour.
By substituting the value

v = 69.6 miles per hour
Thus, the speed of the car at the time of accident is 69.6 miles per hour.
Circle theorem:
The angle at the centre (T) is double the angle at the circumference (Q)
---> That also means that:
The angle at the circumference (Q) is <u>half</u> the angle at the centre (T)
Since T = 130 degrees;
Q = 130 divided by 2
= 65°

Answer:
∠Q = 65°
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent (Angle-Side-Angle or ASA).
Well the area is 13.2²π which = about 547.11 km² if that's what you're asking
