The answer for K and J is 77

The answer for I and H is 43

The diameter of a tire is the distance across the tire through the center. Since tires are circular, you can find the circumference of the tire from the diameter. The circumference represents the distance the tire travels when it makes one revolution. If you know the number of inches in a mile and the circumference, you can find the number of times the wheel turns per mile.

First, measure the diameter of the tire in inches.

Secondly, multiply the diameter by pi, which is approximately 3.1416, to find the tire circumference. For example, if the tire has a 20 inch diameter, multiply 20 by 3.1416 to get 62 inches.

Answer:

D.) Air pollution has steadily decreased since 1999, before suddenly increasing.

Step-by-step explanation:

right on edge

Air pollution has steadily decreased since 1999, before suddenly increasing. Therefore, option D is the correct answer.

A car with low emissions produces very little pollution. A low-emission zone is an area where polluting cars are either not allowed or must pay to enter. They've developed a new kind of low-emission buses.

Vehicles that are either designated as Zero emission Vehicles or as Low Emission Vehicles are considered low-emitting and fuel efficient.

Air pollution has steadily decreased since 1999, before suddenly increasing is the statement best describes air quality in Houston since 1999. As the use of mass transit and transitioning to fuel-efficient or low-emission vehicles.

Therefore, option D is the correct answer.

Step-by-step explanation:

Answer:

Step-by-step explanation:

150 mile by car            x mph

630 mile by plane      3x mph

Total travel time equal 8 hours

    150 / x     mile / (mile / hour)   = hour

    630 / 3x  mile / (mile / hour)   = hour

    150/x + 630/3x  = 8 hours

    450/3x + 630/3x = 8 hours

    450  + 630  = 8(3x)  = 24x

         1080  =  24x

             45  =  x    the rate of the car is 45 mph

The probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given is table showing the results of a survey on the number of text messages per month for people of different ages.

we need to find the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60,

P(E) = favorable outcomes / total outcomes

Favorable outcomes = 157

Total outcomes = 456

Hence the required probability = 157 / 456

Hence the probability that a person texts over 50 messages per month given that the person is between the ages of 23 and 60 is 157/456.

Find the volume of a cylinder with a radius of 3 meters and a height of 13 meters.

[tex] \bullet [/tex] Radius (r) of a cylinder = 3 meters.

[tex] \bullet [/tex] Height (h) of a cylinder = 13 meters.

The volume of a cylinder.

We know,

Formula of Volume of a cylinder is πr²h.

So, Volume of a cylinder = 3.14 × (3)² × 13

Volume of a cylinder = 3.14 × 3 × 3 × 13

Volume of a cylinder = 367.38 cubic meters.

Answer:

17 nickels

8 dimes

Step-by-step explanation:

n + d = 25

.05n + .10d = 1.65

use substitution:  n = 25-d

.05(25-d) + .10d = 1.65

1.25 - .05d + .10d = 1.65

.05d = .40

d = 8    ∴ n = 17

Step-by-step explanation:

Answer:

a_3=4

Step-by-step explanation:

a1 = 100

r = 1/5

an = 100 (1/5)^(n - 1)

so we now have the answer for a_3

a_3 = 100 * (1/5)^(3 - 1)

a_3 = 100 * (1/5)^2

a_3 = 100 * 1/25

a_3 = 4  

i believe this is it, although i'm not entirely sure

good luck :)
