The tires on a compact car are 18 inches in diameter.
a. How far does the car travel after the tires turn once? Use 3.14 as pi
b. How far does the car travel after 12 rotations of the tires? Use 3.14 as pi.
Answer:
1. 56.52 inches
2. 141,300 inches
Step-by-step explanation:
One turn of the tire is the circumference. Therefore, we have to find the circumference first. C = πd = 18π = 18 × 3.14 = 56.52 in
2500 rotations would be 2500 ⋅ 56.52 in = 141,300 in

Step-by-step explanation:
These three theorems, known as Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS), are methods for determining similarity in triangles.
As A has angles 90,25 and 65 and B has angles 90,45 and 45, there are no two pairs of angles that are similar. Also as the angles are not equal the sides can't also be equal. So none of the above three methods are applicable here.

Answer:
Answer:
3.5 fluid ounces
Step-by-step explanation:
In this question, we are asked to calculate the capacity in fluid ounce of a cone-shaped cup.
To solve this, we need to calculate the volume of the cup.
Mathematically, the volume of a cone =
1/3 * π * r^2 * h
Where r = d/2 = 2.7/2 = 1.35 inches
h = 3.3 inches
By substituting this, we have
V = 1/3 * 3.14 * 1.35^2 * 3.3 = 6.3 cubic inch
Now we proceed to calculate the capacity
From the question, we are told that ;
1 fluid ounce = 1.8 cubic inch
This means
x fluid ounce = 6.3 cubic inch
x = 6.3/1.8
x = 3.5 fluid ounces

A triangle has an area of 54 centimeters squared. The height of the triangle is 12 centimeters. What is the base of the triangle?
Answer ASAP! and whoever gets it right can have brainliest
Answer: 9
Step-by-step explanation:
the formula for the area of a triangle is a=bh/2, since the area is 54 we would need to multiply it by 2 which would be 108 to reverse the division. then we would divide it by 12 which would be 9 to reverse the multiplication.
Answer:
[tex]beinggreat78~here.[/tex]
The base is 9
Multiply 9 by 12, which is 108, and divide by 12, which is a way of giving you 9.
WILL CHOOSE BRAINLIEST. Which description most accurately describes the transformation shown below.
Answer:
A
Step-by-step explanation:
The triangle must not translate left because then it will move away from the y-axis, which is not what happens here. So B and C are wrong. D is wrong because if it reflects across the y-axis it won't touch the y-axis, but here it touches so it's wrong.

A square has an area of 169 square feet. Select ALL the values that could represent the side length of the square in feet.
√169
169/4
169/2
13
√13
Answer:
√169 & 13
Step-by-step explanation:
the area of a square is = to one side squared
Because of this, the side should equal the square root of the area.
13 is the square root of 169, and the square root of the area, 169, are both options, and fulfill the area formula for squares

A skateboard was originally priced at $53.00. It is on sale for 15% off. What is the sale price of the skateboard?
Answer:
$45.05
Step-by-step explanation:
To find 10% divide the original number by 10. This is $5.30
To find 5% divide 10% by 2. This is $2.65
Add the two together to get 15%. This is $7.95
Take away the value of 15% from the original number.
$53.00 - $7.95 = $45.05

Answer:
1/2 and -1/2
Step-by-step explanation:
The square root of a fraction is equal to the square root of the numerator divided by the square root of the denominator. In this case, it is √1 / √4. The square root of 1 is still 1, so 1 is the numerator. The square root of 4 is 2, so 2 is the denominator. The fraction is 1 / 2. However, if you square -1/2, you also get 1/4, just like when you square 1/2. Therefore, the second choice is the right option because it has the correct, and number of, answers.

The probability of rolling 2 even numbers is,
⇒ 1 / 4
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Given that;
An experiment involves rolling two dice.
Now, Total possibilities are = 36
And, Number of possibilities to getting even numbers = 9
Hence, The probability of rolling 2 even numbers is,
⇒ 9 / 36
⇒ 1 / 4
Thus, The probability of rolling 2 even numbers is,

Answer:
Option (d) is correct.
Slope of given line y = 5x -4 is 5
Step-by-step explanation:
Given equation of line as y = 5x - 4
We have to find the slope of given line.
For the general equation of line y = mx + c , where m is the slope of line and c is the y- intercept.
Slope of line is given by derivative the equation of line with respect to x, that is
Consider the given equation y = 5x - 4
then slope is
Thus, slope of liven line is 5 .
Also, by comparing the given equation with general equation the slope of line is 5 .
Thus, option (d) is correct.
