Inaccurate. The triangles are similar, but the triangles are named incorrectly. The vertices are listed out of corresponding order.
Inaccurate. The triangles are not similar because angle M is not congruent to angle H, and angle N is not congruent to angle G.
Answers
The correct option regarding whether the triangles are similar is given by:
Inaccurate. The triangles are not similar because angle M is not congruent to angle H, and angle N is not congruent to angle G.
What are similar triangles?Similar triangles are triangles that have congruent angles, that is, angles with the same measure.
Considering that the sum of the internal angles of a triangle is of 180º, the third angle of triangle FGH is given as follows:
98.6 + 61.1 + x = 180
x = 180 - (98.6 + 61.1)
x = 20.3º.
The second triangle has an angle of 20.3º, hence they are not similar, and the correct option is given by:
Inaccurate. The triangles are not similar because angle M is not congruent to angle H, and angle N is not congruent to angle G.

What are expenses?It is defined as the money spends on the utility, the amount of money is required to buy something, in other words, it is the outflow of money from the sole earner's income or the money incurred by any organization.
We have:
Sally took money from her bank account to go out of town for an audition.
The expeses = (7.90 + 15.10) ÷ (1 - 1/2) = $46
Total money = 54 + 46

Slope of AB = 4/3, Slope of BC = -2/7, Slope of CD = 4/3, Slope of AD = -2/7 and Quadrilateral ABCD is a parallelogram because both pairs of opposite sides are parallel.
How to find the slope of a quadrilateral?We are given the coordinates of the quadrilateral ABCD as;
A(−5, 1), B(−2, 5), C(5, 3), and D(2, −1).
Slope of AB = (5 - 1)/(-2 + 5) = 4/3
Slope of BC = (3 - 5)/(5 + 2) = -2/7
Slope of CD = (-1 - 3)/(2 - 5) = 4/3
Slope of AD = (-1 - 1)/(2 + 5) = -2/7
Thus we can see that both pairs of slope are equal which denotes that both pairs are parallel.

The test static used for this procedure is Aspin Welch's t-test.
What is Aspin Welch's T-test?
A variation of the Student's t-test used to determine if two sample means are substantially different is known as the Aspin Welch's T - test for Unequal Variances (also known as Welch's t-test, Welch's adjusted T, or unequal variances t-test). The test's degrees of freedom have been changed, which generally boosts the test's power for samples with unequal variance.
The means being equal is the test's null hypothesis.The notion that the means are not equal serves as the test's alternate hypothesis.Formula for Aspin Welch's T - test
The t-statistic in Aspin Welch's T-test is given as,
t = [tex]\frac{X' - X}{\sqrt{\frac{S1^{2} }{N1^{2} } -\frac{S2^{2} }{N2^{2} } } }[/tex]
Here, X' is the mean of the sample
X is the mean of the population
S1 and S2 are the respective standard deviations for the two samples
N1 and N2 are the respective strength of samples.
Calculating t-statistic for Aspin Welch's T-test
Given that,
X'-X = 1.33
[tex]\sqrt{\frac{S1^{2} }{N1^{2} } -\frac{S2^{2} }{N2^{2} } } = 2.90[/tex]

For two triangles to be similar there sides should be in the same ratio.
For ΔABC ~ ΔMNO,
AB/MN should be equal to BC/NO,
AB/MN = 15/35 = 0.4286
BC/NO = 8/12 = 0.66
Thus, there are not similar triangles.
For ΔABC ~ ΔDEF,
AB/MN should be equal to BC/NO,
AB/DE = 15/22.5 = 0.66
BC/EF = 8/12 = 0.66
Thus, there are similar triangles.
For ΔABC ~ ΔGHI,
AB/GH should be equal to BC/HI,
AB/MN = 15/77 = 0.1948
BC/NO = 8/36 = 0.222

6. Plot the points from the Fahrenheit chart in question 4 onto the graph below. Use the plotted points to sketch out the graph of F(t). (3 points: 2 points for correct coordinates, 1 point for correct shape)
7. Compare the graph in question 6 (F(t)) with the graph in question 2 (C(t)). What changes were made to the graph of C(t) to transform it to F(t)? (1 point)
Answers
The changes that transform C(t) to F(t) is that the function C(t) is stretched vertically to form the function F(t)
How to transform the function?The Fahrenheit function
The Celsius function is given as:
C(t) = -0.30 (t – 12)² + 40
The conversion from Celsius to Fahrenheit is
F(t) = 9/5 * C(t)
Hence, the Fahrenheit function is F(t) = 9/5 * C(t)
Convert values from Celsius to Fahrenheit
The values are t = 0, 12 and 24.
So, we have:
F(0) = -0.54(0 - 12)² + 72 = -5.76
F(12) = -0.54(12 - 12)² + 72 = 72
F(24) = -0.54(24 - 12)² + 72 = -5.76
The new function F(t)
The conversion from Celsius to Fahrenheit is
F(t) = 9/5 * C(t)
So, we have:
F(t) = 9/5 * (-0.30 (t – 12)² + 40)
Expand
F(t) = -0.54(t – 12)² + 72
Hence, the new function is F(t) = -0.54(t – 12)² + 72
The graph of function F(t)
See attachment for the graph of function F(t)
The changes that transform C(t) to F(t)
We have:
C(t) = -0.30 (t – 12)² + 40
F(t) = 9/5 * C(t)
The above implies that the function C(t) is stretched vertically to form the function F(t)

Question 10 How many cubic yards of sand will it take to fill a child's play area that measures 10 yards long, 8 yards wide, and 1/3 yard deep
Answers
Answer:
26.6 cubic yards
Step-by-step explanation:
Remark
What you have is a rectangle prism. It has an easy enough formula.
Formula
V = L *w * h
Givens
L = 10 yards
w = 8 yards
h = 1/3 yards
Solution
V = L*w*h
V = 10 * 8 * 1/3
V = 26.66 yds^3
what is the probability of hitting a triangle on this dashboard?
Answers
Answer: 9/110
Step-by-step explanation:
11*20=220
3*3/2*4=18
18/220=9/110
Answer:
P = 9/110
Step-by-step explanation:
Area of all triangles
[tex]4(\frac{(3)(3)}{2}) =4(\frac{9}{2}) =18[/tex]
Area of the rectangle
[tex](20)(11)=220[/tex]
Probability of hit
[tex]P=\frac{18}{220}= \frac{9}{110}[/tex]

The function f(x) = three-fourths(10)–x is reflected across the x-axis to create the function g(x). which ordered pair is on g(x)?
Answers
The ordered pair that is on g(x) is (2, -3/400)
determine the ordered pair:
The function is given as:
f(x)=3/4(10)∧-x
The rule of reflection across the x-axis is:
g(x) = -f(x)
So, we have:
g(x) = -3/4(10)∧-x
Set x = 2.
So, we have:
g(2) = -3/4(10)∧-2
Evaluate the exponent
g(2) = -3/4 * 1/100
Evaluate the product
g(2) = -3/400
This means that:
(x, y) = (2, -3/400)
Hence, the ordered pair that is on g(x) is (2, -3/400)
Ordered pairs are pairs of two numbers (or variables) that are enclosed in parentheses and separated by commas. For example, (1, 2) is an ordered pair. Coordinate geometry represents points, and set theory represents elements of relations / Cartesian products.
Ordered pairs are pairs of numbers in a particular order. For example, (1, 2) and (-4, 12) are ordered pairs. The order of the two numbers is important. (1, 2) is not equivalent to (2, 1)-(1, 2) ≠ (2, 1).

You are pouring canned sodas Into a cylindrical pitcher. Each can
of soda is 12 cm tall and has a diameter of 6.5 cm. The pitcher is
36 cm tall and has a diameter of 20 cm. How many cans of soda
will the pitcher hold?
Answers
Answer: 28.40 cans of soda
Step-by-step explanation:
Volume of cylinder: pi * r^2 * h
Volume of the can of soda = pi * 3.25^2 * 12 = 126.75 pi
Volume of the cylindrical pitcher = pi * 10^2 * 36 = 3600 pi
3600/126.75: 28.40 cans of soda
Answer:
28 whole soda cans or 28.4 soda cans (rounding to nearest tenth)
Step-by-step explanation:
The soda cans and the pitcher can be modeled as cylinders.
Volume of a cylinder
[tex]\sf Volume=\pi r^2h[/tex]
where:
r is the radiush is the heightDiameter of circle
[tex]\sf d= 2r[/tex]
[tex]\sf \implies r=\dfrac{1}{2}d[/tex]
Volume of Soda can
Given values:
d = 6.5 ⇒ r = 3.25 cmh = 12 cm[tex]\begin{aligned}\sf \implies Volume & = \sf \pi (3.25)^2 \cdot 12\\ & = \sf 126.75 \pi \:\:cm^3\end{aligned}[/tex]
Volume of Pitcher
Given values:
d = 20 ⇒ r = 10 cmh = 36 cm[tex]\begin{aligned}\sf \implies Volume & = \sf \pi (10)^2 \cdot 36\\ & = \sf 3600 \pi \:\:cm^3\end{aligned}[/tex]
To calculate how many cans of soda the pitcher will hold, divide the volume of the pitcher by the volume of one soda can:
[tex]\begin{aligned}\implies \textsf{Number of soda cans} & = \dfrac{\textsf{Volume of Pitcher}}{\textsf{Volume of one soda can}}\\\\&= \sf\dfrac{3600 \pi}{126.75 \pi}\\\\& = \sf 28.402366...\end{aligned}[/tex]
Therefore, the pitcher can hold 28 soda cans (nearest whole can), or 28.4 soda cans (nearest tenth).
