similar
Answers
Answer:
They are similar using the angle-angle property.
Step-by-step explanation:
Since you know that 2 of the angles are congruent, you can use this to prove triangle similarity.
By AA similarity, triangle PQR similar to triangle STU.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The two given triangles PQR and STU.
Here, ∠P=63° and ∠R=45°
In triangle STU, ∠S=63° and ∠U=45°
Now, ∠P=∠S=63° and ∠R=∠U=45°
Since angles of triangle are congruent
By AA similarity, ΔPQR similar to ΔSTU
Therefore, triangles are similar.

A marathon is 26.2 miles long. Jarrod is running a marathon and has completed 17.75 miles. How
many more miles to the finish line?
Answers
Answer:
Jarron has 8.45 more miles to get to the finish line.
Step-by-step explanation:
All we have to do is subtract the total number of miles by the number of miles Jarron has completed.
So: 26.20 - 17.75 = 8.45
26.2 - 17.75 = 8.45
All you need is subtraction because you are finding what is left.
You can find 8.45 by using a calculator or solving in your head, it would just take longer.

Benny the Barber (see Question 1) is considering the addition of a second chair. Customers would be selected for a haircut on a FCFS basis from those waiting. Benny has assumed that both barbers would take an average of 20 minutes to give a haircut, and that business would remain unchanged with customers arriving at a rate of two per hour. Find the following information to help Benny decide if a second chair should be added: Part (a): The average number of customers waiting. Part (b): The average time a customer waits. Part (c): The average time a customer is in the shop.
Answers
According to the information presented, Benny should decide not to add a second chair because the average number of clients waiting is 1 (very low), the average waiting time for a client is 10 minutes (very low), and the average time a customer is in the store is 20 minutes (very low).
According to the information, an average of 2 clients arrive at the hairdresser for every hour (60 min) and each cut takes a maximum of 20 minutes. Therefore, the hairdresser would have an average of 40 minutes busy and 20 minutes free for each hour.
Additionally, customers who must wait do not have to spend a long time waiting in the store because the maximum waiting time is 10 minutes (in the case that both customers arrive at the same time).
Below is a graph where the information of both cases is compared (with an additional chair and without an additional chair) and it is inferred that an additional chair is not necessary because the number of clients waiting and the waiting time is not high.

The red graph is shifted right by 1 from the black graph, so its function would be f(x -1) before it is reflected across the x-axis. Normally, such a reflection will be done by multiplying f(x) by a negative number. Here, that negative number is used to divide y, instead.
The transformation would normally be expected to be ...
y = -1·f(x -1)
By dividing by -1, this becomes ...
y/(-1) = f(x -1) . . . . . . equation of the red graph

Answers
Answer:
Part A: h(t) = ⅔t + 64
Part B: The toddler's height increases by 0.67 cm for every increase in age of 1 month.
Step-by-step explanation:
Given the graph of a linear function that models the relationship between the height, h, and age in months, t.
Part A:In order to establish the linear function, we must first identify the slope or the rate of change to further gain an understanding how the height varies with age over time. To solve for the slope, choose two points from the graph:
Let (x₁, y₁) = (18, 76)
(x₂, y₂) = (21, 78)
Substitute these values into the following slope formula:
[tex]\mathsf{\textbf\:m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
[tex]\mathsf{\textbf\:m = \frac {78\: -\:76}{21\: -\: 18}\: =\:\textbf\:\frac{2}{3}}[/tex]
Therefore, the slope of the line is ⅔.
To find the y-intercept, or the initial value for the height, use the slope, m = ⅔, and another point from the graph, (18, 76), to solve for the y-intercept, b.
h(t) = ⅔t + b
76 = ⅔(18) + b
76 = 12 + b
Subtract 12 from both sides:
76 - 12 = 12 - 12 + b
64 = b
Hence, the linear function that expresses the height as a function of age is:
h(t) = ⅔t + 64.Part B:Based on the graph, the toddler's height increases by 0.67 cm for every increase in age of 1 month. Between the ages of 15 and 18 months, a toddler grows by 2 cm. Solving algebraically, we can determine how much the toddler grew by the 16th month by substituting t = 16 into the function:
h(16) = ⅔(16) + 64
h(16) = 10.67 + 64
h(16) = 74.67
It shows on the graph that the toddler's height at 15 months is 74 cm. Our solution here in Part B shows that the toddler grew 0.67 cm by the 16th month.
Write a function in any form that would match the graph shown below
