Michelle's car needs repairs. The mechanic said it will be $144 for parts plus $80 an hour to repair the car. How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?

Answers

Answer:

3 hours

Step-by-step explanation:

Total cost = 144 + 80h

Where h = number of hours

How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?

384 = 144 + 80h

Subtract 144 from both sides

384 - 144 = 144 + 80h - 144

384 - 144 = 80h

240 = 80h

Divide both sides by 80

h = 240 / 80

= 3

h = 3 hours

PLEASE HELP!! Determine whether the triangles are similar. If similar state how (AA~,SSS~, or SAS~), and write a similarity statement

Answers

Answer:

Yes they are similar because of SAS similarity

Step-by-step explanation:

the side lengths are proportional to each other, and the angle in the middle of the sides is the same size, therefore it has Side Angle Side (SAS) similarity.

ΔTSR ~ ΔFEG by the SAS Similarity Theorem

What is the SAS Similarity Theorem?

SAS Similarity Theorem states that two triangles with two pairs of proportionate sides and a pair of included angle are similar to each other.

In the image given, the two triangles have:

Two pairs of proportional sides - TS/FG = TR/FE = 3.A pair of congruent included angles - ∠T ≅ ∠F.

This means they are similar by the SAS Similarity Theorem.

Therefore, ΔTSR ~ ΔFEG by the SAS Similarity Theorem.

Find the exact length of the third side.

Answer:

[tex]24x^{2} +7x^{2} =[/tex]

step-by-step explanation:

You have to solve this to get your answer. This is a case where you have to use the pythagorean theorem.

Answer:

this is a right angle triangle.

which means that we can use hypotenuse theorem to solve it.

the hypotenuse theorem:-

a^2 +b^2 =c^2

where a and b are the sides opposite to the hypotenuse.

[(the longest side) the longest side of the triangle is always opposite to the right angle]

so...

a = 24

b = 7

a^2 + b^2 = c^2

24^2 + 7^2 = c^2

576 + 49 = c^2

625 = c^2

don't stop here, you could lose marks. I have seen my classmates do this silly and small mistake and lose 1/2 a mark.

√625 = c

25 = c

thus the length of the third side is 25.

The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 is graphed below. On a coordinate plane, 2 lines intersect at (0, negative 1). What is the solution to the system of equations? (0, –1) (–1, 0) (0, 1) (1, 0)

Answers

Answer:

0, -1

Step-by-step explanation:

trust me I just took the exam on edge 2020

The solution to the given system of equations will be (0, -1). which is the correct option (B).

What is the Linear equation?

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of linear equations y = 2 x minus 1 and y = negative 4 x minus 1 which is given in the question.

y = 2x - 1     ....(i)

y = -4x - 1   ....(ii)

Substitute the value of equation (i) in equation (ii) and solve for variable x :

2x - 1 = -4x - 1

Rearrange the terms of variable "x" and combine them,

2x + 4x = -1 + 1

6x = 0

x = 0

Substitute the value of x = 0 in equation (ii) and solve for variable y :

y = -4(0) - 1

y = -1

Therefore, the solution to the given system of equations will be (0, -1).
