Answer:
Straight line is 180 degrees
Subtract what you know 180-55-90 = 35
(6r-7)=35
35-7=28
28/6=4.66666
r=4.6666
Answer:
7
Step-by-step explanation:
90(right angle) + 55(Acute angle) = 145.
We know the whole angle equals 180 because it is 2 right angles. 90 + 90.
So, we will do 180 - 145 = 35.
Now we know our mystery angle equals 35.
To figure out r, we will do 35 + 7 = 42.
Then, 42 is divided by 6 and gets 7.
Therefore, 7 would be your answer.

What is the slope of the line passing through the points (8, 9) and (-2, 9)?
Answers
Answer:
Slope is 0
Step-by-step explanation:
First, find the difference in the x and y of each point by subtraction.
8 - (-2) = 10
9 - 9 = 0
Because the y value doesn't change in between these two points, that indicates the slope is 0

Answer:

Step-by-step explanation:
20-9 = 11 then 5x11=55
So then you need to use the distributive property, multiply 5 to t and 5 to -9.
Like this:
5t - 45 + 12
Then combining like terms, -45 and 12 are like terms because don’t have any letter.
5t - 33

The heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively. What is the height of Roger if the mean of all of them is 158cm?
Answers
Answer:
The height of Roger is 158cm
Step-by-step explanation:
All of them=158cm
They are 4.So,158^4=632cm
Height of 3 persons=155cm+158cm+161cm=474cm
Therefore the height of Roger is 632cm-474cm=158cm
The height of Roger with the mean of all of them is given is 158 cm.
Given that, the heights of Karina, Miya and Clint were 155cm, 158cm, and 161cm respectively.
What is mean?In statistics, the mean refers to the average of a set of values. The mean can be computed in a number of ways, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations).
Let the height of Roger be R.
Mean= 158 cm
We know that, mean =Sum of all the observations/Number of observations
⇒ (155+158+161+R)/4 =158
⇒ 474+R=632
⇒ R=632-474
⇒ R=158 cm
Hence, the height of Roger with the mean of all of them is given is 158 cm.

For the functions u(t) = 7t - 2 and s(t) = t² - 9. s(u(2)) = 135
What is a function?A function is a mathematical equation that shows the relationship between two variables.
For the functions u(t) = 7t - 2 and s(t) = t² - 9.To find what is s(u(2)), we proceed as follows.
Since u(t) = 7t - 2. Then u(2) is evaluated when t = 2. So, we have that
u(t) = 7t - 2
u(2) = 7(2) - 2
u(2) = 14 - 2
u(2) = 12
Now, since u(2) = 12 and s(t) = t² - 9
s(u(2)) is evaluated as follows
s(t) = t² - 9
s(u(2)) = 12² - 9
s(u(2)) = 144 - 9
s(u(2)) = 135
So, s(u(2)) = 135

The answer is photo.
Step-by-step explanation:
So:
167 - 66 = 101
So the total of Spain is 101
Now what is Marc’s value for Spain?
33 + 40 = 73
101 - 73 = 28
Marc’s value is 28.
Elli’s value for Portugal is unknown. We know Elli’s total is 57 and her value for Spain is 40. So: 57 - 40 = 17.
Elli’s value for Portugal is 17.
Now what is Marc’s total?
We know Spain is 28 and Portugal is 24. So add them:
28 + 24 = 52
Marc’s total is 52.
Now, what is Raisa’s total. We everyone else’s total and we know it all adds up to 167 so:
57 + 52 = 109
167 - 109 = 58
Raisa’s total is 58.
What is her Portugal value?
58 - 33 = 25
Her Portugal value is 25.
