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 )
54.7

A juice factory offers its juice in both bottles and cans. A class of students on a field trip decides to compare the numbers of cases of bottled juice and canned juice that are packaged each minute. The students count the number of cases that are packaged on each assembly line over several minutes.
What is the unit rate for canned juice, in cases per minute? Explain how you found this unit rate.
Answers
Answer: 50 cases per minute
Step-by-step explanation:
1. Select one of the points on the graph. Let's use (2, 100) in this case.
2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.
3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

First do the square 6x6=36
Then do the 2 triangles
3x10=30
(Normally you would divide the answer by 2 since a triangle is half of a square but since there is another triangle this is not needed)
After that add the area of the square to the area of the 2 triangles and your answer is 66
The mean of four numbers is 7. Three of the numbers are 5, 7, and 7. What is the fourth number? Show your work.
Answers
Answer:
4th number = 9Step-by-step explanation:
let 4th number = X
mean = 7
observations = 5, 7, 7, X
..............................................
mean = sum of observations ÷ numbers of observations
7 = 5+7+7+X ÷ 4
28 = 19 + X
28 - 19 = X
9 = X
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7. So, the 4th number would be 9.
How to find the mean value of a data set?The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.
If the data set consists of values
[tex]x_1, x_2, ..., x_n[/tex]
, then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7.
let 4th number = X
Mean = 7
observations = 5, 7, 7, X
Mean = sum of observations / numbers of observations
[tex]7 = 5+7+7+X / 4\\28 = 19 + X\\28 - 19 = X\\9 = X[/tex]
