Answer: B: 3
Step-by-step explanation:
3. In the diagram below AB' is the image of AB after a reflection in AC. If mBAC4x7 and mBAB ' 64 , then which of the following is the value of x?
(1) 6.25 (3) 14.25 (2) 12.5 (4) 18.75
When a line or shape or point is reflected, it must be reflected over a line.
The value of x is (b) 14.25
Reflection is a rigid transformation;
This means that:
[tex]\mathbf{\angle AC = \angle AB}[/tex]
So, we have
[tex]\mathbf{4x + 7 = 64}[/tex]
Subtract 7 from both sides
[tex]\mathbf{4x = 57}[/tex]
Divide both sides by 4
[tex]\mathbf{x = 14.25}[/tex]
Hence, the value of x is (b) 14.25

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h. Car A traveled 22 mph faster than Car B.
How fast did Car A travel?
(The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.)
Enter your answer in the box.
Answer:
We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Step-by-step explanation:
Answer:
Step-by-step explanation:
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.

The length of Chen’s office is 15.5 feet and the width is 7.8 feet. Use the formula P = 2ℓ + 2w to find the perimeter of the office.
46.6 feet
Step-by-step explanation:
P = 2ℓ + 2w
P = 2(ℓ + w)
P = 2(15.5 + 7.8)
P = 2(23.3)
P = 46.6 feet

A salesperson works 40 hours per week at a job where has two options for being paid. Option A is an hourly wage of 23$. Option B is a commission rate of 10% on weekly sales. How much does need to sell this week to earn the same amount with the two options
Answer:
$9200
Step-by-step explanation:
Since he works 40 hours a week and would make $23 for every hour with option A, we just multiply 40 by 23
40 x 23 = 920
This means 10% of the sales will need to equal to 920
Let x = sales
We multiply x by 0.1 to get 920
0.1x = 920
Divide both sides by 0.1
0.1x/0.1 = 920/0.1
x = 9200
