Sofia has 25 coins in nickels and dimes in her pocket for a total of $1.65. How many of each type of coin does she have?
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

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.

An angle measured 140 more than the measure of its supplementary angle. What is the measure of each angle ?
Answer:
Supplementary angle equals 180°
Complementary angle equals 360°
Step-by-step explanation:
Conjugate angles are more or less related to complementary and supplementary angles. The sum of the two angles put together equals 360 degrees. The last angle that will be named is straight. The measure of the angle equals 180 degrees.

=16.7551608191
≈16.8km
Answer:
16.8 km
Step-by-step explanation:
Arc length = 2πr (θ/360)
So plug in the values:
2π(8)(120/360) = 16π(1/3) = 16π/3
16.75516 ——————> 16.8 km

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

In a class of students, the following data table summarizes how many students have a brother or a sister.
We have to determine the probability that a student chosen randomly from the class has a sister.
What is the formula for probability?The probability is the ratio of the number of favorable outcomes to the total outcomes in that sample space. It is expressed as, Probability of an event P(E) = (Number of favorable outcomes) ÷ (Sample space).
Therefore the probability is 5/30 chance of it happening.

find the volume of this cylinder. round to the nearest tenth
Answer:3418
Step-by-step explanation:
The volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.
To find the volume of a cylinder, you can use the formula:
Volume = π * r² * h
Given:
Radius (r) = 8 ft
Height (h) = 17 ft
Plugging these values into the formula, we can calculate the volume:
Volume = π * (8 ft)² * 17 ft
= π * 64 ft² * 17 ft
≈ 3418.05 ft³
Rounding the volume to the nearest tenth, we get:
Volume ≈ 3418.1 ft³
Therefore, the volume of the cylinder, rounded to the nearest tenth, is approximately 3418.1 ft³.

Read the passage from the Houston Chronicle about air quality in Houston in 2019. “I’m surprised and disturbed that Houston’s air quality worsened in this year’s [American Lung Association ‘State of the Air’] report,” said Luke Metzger, director of Environment Texas. “The trend since 1999 had been one of steady progress and instead now it seems we are backtracking and that’s bad news particularly for the hundreds of thousands of people who have asthma or other vulnerable populations like senior citizens. . . .” Current models estimate that more than 60 percent of ozone pollution is from cars, according to Raun, and to address that, the city is trying to encourage practices such as the use of mass transit and transitioning to fuel-efficient or low-emission vehicles. Which statement best describes air quality in Houston since 1999? Air pollution has been steadily increasing in Houston since 1999. Air pollution has been steadily decreasing in Houston since 1999. Air pollution has varied depending on climate conditions since 1999. Air pollution has steadily decreased since 1999, before suddenly increasin
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.
What is low-emission?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.

Hypotenuse is x
Altitude is 12 cm.
Base is 5 cm.
Substituting the given values in the Pythagoras equation:-
[tex]x^{2} = 5^{2} +12^{2}[/tex]
[tex]x^{2} = 25 + 144[/tex]
[tex]x = \sqrt{25+144}[/tex]
