Answer:
∠ T ≈ 54.7°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos T = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{ST}{TU}[/tex] = [tex]\frac{\sqrt{21} }{3\sqrt{7} }[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] , then
∠ T = [tex]cos^{-1}[/tex] ([tex]\frac{\sqrt{3} }{3}[/tex] ) ≈ 54.7° ( to 1 dec. place )

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
a = 6 sides
Length of one side = 2 cm
So , total length of one side = 2 x 6 = 12 cm
Now , area of square = ( 12 )² = 144 cm²
And , the area of shaded portion A = area of square - area of triangle
Area of triangle = ( 1/2 ) ( 12 ) ( 12 )
Area of triangle = 72 cm²
Now , A = 144 - 72
A = 72 cm²
Hence , the area is A = 72 cm²

Which of the following is true about similar triangles?
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

A class contains 12 female and 20 male students. Find the probability that when two students are chosen randomly from the class, the first student is male and the second student is female.
Write the probability as a fraction in the simplest form.
Answer:
15 / 62
Step-by-step explanation:
Since there 32 students, of which 20 are male, the probability of selecting a student and them being male first is 20/32.
The probability of selecting another student and they are female is 12/31, because the male student is counted out of the selection because he is already picked.
This makes the probability 20/32 x 12/31 = 15 / 62
The average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014. What was the percent change in the average cost of a gallon of gas in 2014? Round to the nearest percent. The average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014. What was the percent change in the average cost of a gallon of gas in 2014? Round to the nearest percent.
The percentage change of the gas will be 45%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014.
The percentage change will be calculated as,
Percentage change = ( 3.42 - 2.36 ) / 2.36
Percentage change = ( 1.06 / 2.36 )
Percentage change = 0.45 x 100
Percentage change = 45%

Mrs. Canter's math class went outside and plucked blades of grass and then measured them. The line plot shows what fraction of an inch 12 of the blades of grass were. What is the difference of the length of the shortest blade of grass and the length of the longest blade of grass? Write your answer as a mixed number in simplest form.
Answer: 1 1/4
Step-by-step explanation: The shortest blade of grass is 2/4 of an inch. The tallest blade of grass is 7/4 inches. You must subtract 7/4 by 2/4 to get the answer. Subtract the numerator of the tallest blade of grass by the smallest blade of grass. 7/4-2/4=5/4. When you convert that to a mixed number you get 1 1/4.

Answer:
9. 0.016 pounds (Malika - 1.032; Adrian - 1.016)
10. The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016).
Step-by-step explanation:
Question #9 asks about the difference between mean masses, so what we need to do first is add up each of the value, and then divide them by 5.
Malika:
(1.1 + 1.08 + 1.05 + 0.95 + 0.98)/5
(2.18 + 2 + 0.98)/5
(3.16 + 2)/5
5.16/5
1.032 is the mean mass for Malika's containers.
Adrian:
(1.3 + 1.21 + 0.79 + 0.9 + 0.88)/5
(2.51 + 1.69 + 0.88)/5
(2.51 + 2.57)/5
5.08/5
1.016 is the mean for Adrian's containers.
Then, subtract the two means.
1.032 - 1.016
The difference between the means is 0.016 pounds (#9's answer).
With that information, we can quickly answer #10. For example, I've put:
The best inference I can create that is supported by this data set is that Malika put more potato salad per container (1.032) than Adrian did (1.016). (My answer for #10.)
