During a road trip Tony , Tony drove one third the distance that Lana drove. Mark drives 15 more than Lana drove .The total dist

ale4655 [162]

Answer:

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles

Step-by-step explanation:

Given as :

The total distance cover by Lana , Tony , Mark = 484 miles

Let The distance drove by Lana = L miles

The distance drove by Tony = T

The distance cover by Mark = M

So , L + T + M = 484 miles

Now, The distance of Tony = $\frac{1}{3}$ of Lana distance

Or, T = $\frac{1}{3}$ × L

And The distance of Mark = 15 + The distance of Lana

Or, M = 15 + L

Now.

L + $\frac{1}{3}$ × L + 15 + L = 484

Or, 2 L + $\frac{L}{3}$ = 484 - 15

Or, 2 L + $\frac{L}{3}$ = 469

Or, $\frac{7 L}{3}$ = 469

Or, 7 L = 469 × 3

∴ L = $\frac{1407}{7}$

I.e L = 201

The distance drive by Lana = 201 miles

The distance drive by Mark = 15 + L =15 + 201 = 216 miles

The distance drive by Tony = $\frac{1}{3}$ × 201 = 67 miles

Hence The distance drive by each person is

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles Answer

I need help Circle P is below

iragen [17]

1. remember all of them add up equal to 360 degree.
2. add all of them up together
$(4y + 6) + (7y - 7) + (20y - 11) = 360$
3. combine like term then solve for Y
4. you will figure the arc measure of BC when you get answer for Y.

A bicyclist rides 16 miles in 144 minutes. If she continues at this speed, how long will it take her to travel 36 miles? 576 min

Leni [432]

Answer: 324 minutes
Steps:
16 miles equals to 144 minutes
36 miles equals to x minutes

So first divide 144/16 which equals to 9
Then multiply 36×9 which equals to 324 minutes

Classify each situation as exponential growth, exponential decay, or linear.

Harrizon [31]

Answer:

1) exponential decay

2) linear

3) exponential growth

Step-by-step explanation:

1) The first question is like, initially 600 people watched, after 3 days 480.

This means it is decay. The difference in first day and after 3 days is 120.

To be linear, further after 3 days, or from start after 6 days, the population should be 360. But it is given to be 384.

Thus exponential decay.

2) In second, Initially, 400 liters of water is there. After 2 hours, the tank has 340 litres. Thus the loss in 2 hours is (400 - 340) = 60 liters.

After 4 hours, the loss is (340 -280) = 60 liters.

As the loss is same in equal intervals of time, the decay is linear.

3) In third one, Initially there are 512 birds.

After 2 years there are 768 birds, thus the growth is (768-512) =256.

After 4 years, There are 1152 birds. Thus the growth is (1152 - 768) = 384.

Thus the increase is non linear, and so exponential growth.
