Alright, so here, we can simply divide 0.75/3=0.25 due to that we need to find that we need to find the unit rate of each pound, and we have 3, so we need to divide by 3

Of the 1,640 students enrolled at a school, 50% come to school by bus, 35% come by car, and the rest of the students walk home.

ehidna [41]

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

A new car is purchased for $50,000 and over time it’s value depreciates by one half every 5 years. What is the value of the car

Setler79 [48]

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

$W = C (1 - \frac{D}{100} )^t$

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:

$W = 50000( 1 - \frac{10}{100} )^7\\\\W = 50000 (\frac{9}{10} )^7\\\\W = 23914.85$

Therefore, the value of the car after 5 years would be $23914.85

(17 points) <br> Determine if line AB is tangent to the circle

zlopas [31]

1. If AB is tangent to the circle, then

$18^2=(2\cdot7.2)^2+10.8^2$

We have

$18^2=324$

$(2\cdot7.2)^2+10.8^2=324$

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,

$(10+8)^2=8^2+15^2$

but we have

$(10+8)^2=324$

$8^2+15^2=289$

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