Determine whether each pair of triangles is similar. Justify your answer.
Answers
Answer:
Your answer is C
Step-by-step explanation:
The definition of similarity is when one shape can become another after a resize, flip, slide or turn.
If you multiply AD, which is 6, by 1.5 you get 9. Which is the length AC.
If you multiply AE, which is 10, by 1.5 you get 15. Which is the length of AB.
Both triangles share angle A, so that leaves you with SAS Similarity.

The shoes you want are $95. They are on sale for 40% off . What is the sale price for the shoe ?
Answers
Answer:
57
Step-by-step explanation:
90 - 40% = 57
Answer:
The shoes would be $57
Step-by-step explanation:
To calculate percentage you use the equation:
P% x N = A
Before we use it we convert the number 40 into the tenths place of a decimal, 0.40.
Now we use it!
.40 x 95 = 38
38 would be 40%, so we remove it from the last total aka 95
95 - 38 = 57

Answer:
B. 8.625 ft²
Step-by-step explanation:
The total area is the sum of the areas of the two rectangular sections and the area of the triangular section. The area formulas are ...
A = LW . . . rectangle
A = 1/2bh . . . triangle
Here, the dimensions are such that we can simplify the problem a bit
total area = (1.5)(2.5) +1/2(1.5)(1.5) + (1.5)(2.5)
= (1.5)(2.5 + 1.5/2 + 2.5)
= (1.5)(5.75) = 8.625 . . . . . ft²
The total surface area of the desk is 8.625 square feet.

Answers
Answer:
24 possible ways
Step-by-step explanation:
When a member is chosen to occupy a leg of the 4-member relay, the same member can not be chosen again, because one member cannot occupy more than one leg.
As one person is chosen to run one leg, the options decrease by one. And like the first leg, one person cannot run more than one leg.
This cycle will repeat until the last person occupies the remaining empty leg.

What is the measure of angle of 1?
Answers
Answer:
m<1 = 118
Step-by-step explanation:
The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that
(28) + (90) = m<1
Remember, a box around an angle signifies that its measure is (90) degrees.
Solve this problem by performing the operation,
118 = m<1

Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80. What is the new mode
Answers
Answer:
83 is still the mode
Step-by-step explanation:
The maximum possible value for the new mode is 83.
What is mode?The data value that is repeated the most in the data set is called the mode of the given data set.
Given is that Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80.
Initially, the mode of the class of 18 students is 83. This means that most of the students scored the 83 marks in the test. After four students took the test, the maximum probability that the mode will remain 83 is the highest. Also, one of the four numbers scored 83 itself.
Therefore, the maximum possible value for the new mode is 83.

Assuming the dark gray area is a straight line, the whole thing should add up to 180*. If we have our 180*, minus 79*, you'll have 101*. BUT, we also have to divide that by two to get our x answer, so the value of x would be 50.5*.
An airline operates a call center to handle customer questions and complaints. The airline monitors a sample of calls to help ensure that the service being provided is of high quality. Ten random samples of calls each were monitored under normal conditions. The center can be thought of as being in control when these samples were taken. The number of calls in each sample of not resulting in a satisfactory resolution for the customer is as follows:
4 5 3 2 3 3 4 6 4 7
Required:
a. What is an estimate of the proportion of calls not resulting in a satisfactory outcome for the customer when the center is in control?
b. Construct the upper and lower limits for a p chart for the manufacturing process, assuming each sample has 100 calls.
Answers
Answer:
A) p = 0.041
B) UCL = 0.1004
LCL = 0
Step-by-step explanation:
We are told that Ten random samples of calls each were monitored .
Thus; n_x = 10
We are told that each sample has 100 calls. Thus; n = 100
A) We are given the number of calls in each sample not resulting in a satisfactory resolution for the customers as;
4 5 3 2 3 3 4 6 4 7
Thus, sum of this is;
Σx = 4 + 5 + 3 + 2 + 3 + 3 + 4 + 6 + 4 + 7
Σx = 41
proportion of calls not resulting in a satisfactory outcome for the customer when the center is in control is given by;
p = Σx/(n_x•n)
p = 41/(10 × 100)
p = 41/1000
p = 0.041
B) let's first find the standard deviation.
It's given by the formula;
σ = √(p(1 - p)/n)
σ = √(0.041(1 - 0.041)/100)
σ = 0.0198
Formula for Upper control limit(UCL) and Lower control limit(LCL) are given as;
UCL = p + 3σ
LCL = p - 3σ
Thus;
UCL = 0.041 + 3(0.0198)
UCL = 0.1004
LCL = 0.041 - 3(0.0198)
LCL = -0.0184
Rule is that when LCL is negative, we adopt LCL = 0.
Thus;
UCL = 0.1004
LCL = 0

Answer:
54 degrees
Step-by-step explanation:
So, lets go over what we know.
Angle PRS is 90 degrees(we can tell by the small square shape inside of the angle)
We also know that Angle PR is 36 degrees.
We need to find x, angle RS.
To do this, lets subtract Angle PR from Angle PRS, or 36 from 90:
90-36
=
54
Since Angle PRS - Angle PR = Anlge RS, this means:
90-36=54
So 54 is our answer!

What is the area of the figure?
Answers
Answer:
b. 366 square inches
Step-by-step explanation:
The area of a triangle is 1/2×Base×Height. There are 2 pairs of identical triangles so you multiply each equation by 2.
2×(1/2×10×12) = 120 in²
2×(1/2×18×12) = 216 in²
120 in² + 216 in² = 336 in²
Answer:
336 square units
Step-by-step explanation:
Generally, to find the area of the given quadrilateral (which is presumably a kite), one uses the following formula,
[tex]\frac{(base)*(hieght)}{2}[/tex]
In this picture, one can see that the diagonals (dotted lines that connect opposite corners) are given, but their measurements are split up as per the segments they are divided into. In order to find the lengths of each diagonal, add up the two parts. To find the area of the figure, substitute the results into the given formula to find the area,
[tex]12+12=24\\\\10 + 18 = 28[/tex]
Substitute,
[tex]\frac{24*28}{2}\\\\=\frac{672}{2}\\\\=336[/tex]
