How Do I Solve This?

Answers

Answer 1

Answer:

Step-by-step explanation:

The first thing you have to do, is rewrite the given expression

[tex]Ar^{-2} = \frac{A}{r^{2} }[/tex]

Then you plug in the given values

[tex]\frac{A}{r^{2} } = \frac{50.265}{4^{2} }[/tex]

Finally you simplify

[tex]\frac{50.265}{4^{2} }=\frac{50.265}{16} = 3.142[/tex]

19. Charlene Levington operates an oil change and tune-up service. She charges $33.95 per oil change. Tune-up is $72.50 for a four- cylinder engine, $82.50 for a six-cylinder engine, and $92.50 for an eight-cylinder engine. What are the charges for a week in which Charlene's facility did 35 oil changes and tuned 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines?​

Answers

$2,240.75

Step-by-step explanation:

just multiply each tune up price by the amount she worked on within that week and add them all up

The charges for the week, including 35 oil changes and tune-ups for 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines, amount to $2308.25.

To calculate the charges for the week, we need to find the total cost for both oil changes and tune-ups.

Charges for Oil Changes:

Charlene did 35 oil changes, and each oil change costs $33.95. So the total charges for oil changes can be calculated as follows:

Total charges for oil changes = Number of oil changes * Cost per oil change

Total charges for oil changes = 35 * $33.95

Total charges for oil changes = $1183.25

Charges for Tune-ups:

For the tune-ups, she serviced 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines. Let's calculate the total charges for each type of engine and then add them together.

Total charges for four-cylinder engine tune-ups = 5 * $72.50 = $362.50

Total charges for six-cylinder engine tune-ups = 7 * $82.50 = $577.50

Total charges for eight-cylinder engine tune-ups = 2 * $92.50 = $185.00

Total charges for all tune-ups = $362.50 + $577.50 + $185.00 = $1125.00

Total Charges for the Week:

Now, let's find the total charges for the entire week by adding the charges for oil changes and tune-ups:

Total charges for the week = Total charges for oil changes + Total charges for all tune-ups

Total charges for the week = $1183.25 + $1125.00 = $2308.25

The charges for the week, including 35 oil changes and tune-ups for 5 four-cylinder engines, 7 six-cylinder engines, and 2 eight-cylinder engines, amount to $2308.25.

The triangle is an isosceles and an obtuse triangle

What Is an Isosceles Triangle?

A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.

In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle

The three types of Isosceles Triangles are :

Isosceles acute triangle

Isosceles right triangle

Isosceles obtuse triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of ∠ABC = 120°

So , it is an obtuse triangle with angle > 90°

Now , the measure of sides AB = measure of BC

So , an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base

Therefore , it is an Isosceles obtuse triangle

Hence , the triangle is isosceles

How are rational numbers and Integers similar? How are they different?

Answers

Answer:

Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers. They are different because Integers include all whole numbers and their negative counterpart e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… is a rational number but not an integer. All rational numbers belong to the real numbers. If two numbers are at the same distance from 0 as in the case of 10 and -10 they are called opposites.

If SF = 5x + 2, SK = 27, and KF = 3x - 1,
find KF.

Answers

Answer:

KF = 35

Step-by-step explanation:

Since it's a line with K in the middle, we know that the distance SF is the same as SK + KF.

(Start at S, first go to K, then continue to F. You've traveled the same distance as from S to F.)

SF = SK + KF

Let's put in the values we got.

5x + 2 = 27 + (3x -1)

Opening the parenthesis.

5x + 2 = 27 + 3x - 1

5x + 2 = 26 + 3x

Now let's subtract 3x from both sides.

2x + 2 = 26

Now, subtract 2 from both sides.

2x = 24

If we divide by 2...

x = 12

We know that...

KF = 3x -1

Since x is 12, let's put that in.

KF = 3 * 12 - 1 = 36 - 1 = 35

Answer: KF is 35 !

Sam made ten to add 7 + 2 + 6 Enter number to complete the equation. Sam first added 7 + 2 = 9. Then he made 10 to find the find the sum. The sum is 4 + 6 = 10 + ? = ?

Answers

Answer:

So we have the addition.

7 + 2 + 6.

First, she added the 7 + 2 = 9

So we can replace that in our addition as:

7 + 2 + 6 = (7 + 2) + 6 = 9  +  6

Now, we can use 9 = 5 + 4, and replace that in the addition.

Then we have:

9 + 6 = (5 + 4) + 6

And we know that 4 + 6 = 10.

Then:

5 + 4 + 6 = 5 + (4 + 6) = 5 + 10 = 15.

What is a line segment?

In geometry, a line segment is a part of a line that is bounded by two distinct end points,and contains every point on the line that is between its endpoints.

Now it is given that,

Point B is on line segment AC

AB = 4x-6

AC = 2x+10

BC = 4

now since Point B is on line segment AC, therefore

AC = AB + AC

⇒ 2x + 10 = 4x - 6 + 4

⇒ 2x + 10 = 4x - 2

⇒ 2x = 12

⇒ x = 6

Put the value of x in AC, we get

AC = 2(6) + 10

or, AC = 12 + 10

or, AC = 22 units.

Hence, the numerical length of AC is 22 units.

Find:

Profit earn each year

Computation:

Assume,

Profit earn 1st year = x

Profit earn 2nd year = 5x

Total profit earn = Profit earn 1st year + Profit earn 2nd year

x + 5x = 613,801.56
