Answer: x = 20
Step-by-step explanation:
The angle is 90 degrees so we can make an equation
with it.
3x + 10 + x = 90
Combine like terms
4x + 10 = 90
subtract 10 from both sides to cancel it out
4x = 80
Now divide by 4 to leave x by itself
x = 20
Now you can check if it's correct by plugging in x to the equation given
3(20) + 10
60 + 10
70
20 + 70 = 90 degrees
Answer:
D: 20 degrees
Step-by-step explanation:
First, we add 3x+10 and x together because they are within a right angle, which is 90 degrees. This gives the equation 4x+10=90. We solve from here.
We subtract 10 from both sides to isolate the x-variable. 90 minus 10 equals 80. This gives us the equation 4x=80. To further isolate the x-variable, we divide both sides by 4. 80 divided by 4 equals 20.
This leaves us with x=20.
Hope this helped!

Using Pemdas:
3 (1 + 4) / 3 + 4^2
3 (5) / 3 + 4^2
3 (5) / 3 + 16
15 / 3 + 16
Answer:
A
Step-by-step explanation:
First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis. simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.
When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.
When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.
When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.
Therefore, Equation A is the correct answer.
Perry used the formula V (t) = 24,450(1-0.13)
to find the value of his car t years after he purchased it.
What does 0.13 represent?
A the price of the new car
B the time of year the car was purchased
the value of the car after t years
a 13% decrease in value each year
Answers
Answer:
D) a 13% decrease in value each year
Step-by-step explanation:
Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.
What does 0.13 represent?
The expression given above represents and expression of exponential decrease.
This is represented by the formula
y = a(1 - r)^t
Where
y = Value after time t
a = Initial value
r = Rate of decrease
t = Time
Comparing both expressions
y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t
We can see that:
r = 0.13
This is the rate of decrease.
Converting to Percentage = 0.13 × 100
= 13%

Frequency: 16 11 9 14 10
Find the probability of spinning each color, based on the data. Explain how you calculated each probability.
Answers
Step-by-step explanation:
Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.
Total frequency = 16 + 11 + 9 + 14 + 10 = 60
Hence we have the following probabilities:
P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6What is the output of this function when the input is -2?

Latoya made $147 for 7 hours of work.
At the same rate, how much would she make for 9 hours of work?
help pls
Answers
Answer:
$189 in 9 hrs
Step-by-step explanation:
Division is one of the four fundamental arithmetic operations. The amount that Latoya will make by working 9 hours is $189.
What is Division?The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.
Given that Latoya made $147 for 7 hours of work. Therefore, we can write,
Money made in an hour = Total Amount / Number of hours
= $147 / 7 hours
= $21 per hour
Now, the amount that Latoya will make in 9 hours will be,
Amount for 9 hours of work = Money made in an hour × Number of hours
= $21 per hour × 9 hours
= $189
Hence, the amount that Latoya will make by working 9 hours is $189.
