So first we need to find what percent of the students walk to school.
50 + 35 = 85% don't walk leaving only 15% that walk to school,
To find the 15% percent that DO walk we multiply .15 by the total number of people.
.15 x 1640 = 246 people walk to school
Answer:
31.5
Step-by-step explanation:
The value of the car after 5 years would be $23914.85
<u>Explanation:</u>
Given:
Worth of the new car = $50,000
Every 5 years the value depreciates by 1/2
i.e., every 5 years the value depreciates by 50%
So, we can say that every year the value depreciates by 10%
The worth of the car after 7 years would be

where,
W is the depreciated value
C is the current value
D is the depreciation rate
t is the time
Substituting the value in the equation we get:

Therefore, the value of the car after 5 years would be $23914.85
1. If AB is tangent to the circle, then

We have


so AB is indeed tangent to the circle.
2. The unlabeled leg is another radius of the circle so it has length 8. Then if AB is tangent to the circle,

but we have


so that cannot be a right triangle and AB is not tangent to the circle.
