Answer:
40
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40
Answer:
Required Answer :-Let the number of sides=x
Each angle measures 9°As we know that in a polygon
[tex]{\boxed{\sf Sum\;of\:exterior\:angles=360°}}[/tex]
Substitute the values[tex]{:}\longrightarrow[/tex][tex]\sf 9x=360 [/tex]
[tex]{:}\longrightarrow[/tex][tex]\sf x={\dfrac {360}{9}}[/tex]
[tex]{:}\longrightarrow[/tex][tex]\sf x=40 [/tex]
[tex]\therefore[/tex]Number of sides=40.
Which number is greater than the absolute value of − 3 8 ?
Answer: i have no idea what number you tried to say but here are a few options for what it could be...
the absolute value of -3 is 3
the absolute value of 8 is 8
the absolute value of -3/8 is 3/8
the absolute value of -38 is 38
Step-by-step explanation:
absolute value means how far the number is from zero, it does not take into account whether the number is positive or negative
2.
The bus is 33.5 feet long. The city train is 45.9 feet longer than the bus. How long
is the city train?
Answer:
88.4
Step-by-step explanation:
33.5 + 45.9 = 88.4
The length of the city train is 79.4 feet.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Length of the Bus = 33.5 feet.
Length of the City train:
= Length of the Bus + 45.9
= 33.5 + 45.9
= 79.4 feet.
Thus,
The city train is 79.4 feet.

Answer:
(3, 10 ) and (7, 30 )
Step-by-step explanation:
Given the 2 equations
5x - y = 5 → (1)
2y - x² = 11 → (2)
Rearrange (1) expressing y in terms of x
y = 5x - 5 → (3)
Substitute y = 5x - 5 into (2)
2(5x - 5) - x² = 11
10x - 10 - x² = 11 ← rearrange into standard form
x² - 10x + 21 = 0 ← in standard form
(x - 3)(x - 7) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 7 = 0 ⇒ x = 7
Substitute these values into (3) for corresponding values of y
x = 3 → y = 5(3) - 5 = 15 - 5 = 10 ⇒ (3, 10 )
x = 7 → y = 5(7) - 5 = 35 - 5 = 30 ⇒ (7, 30 )
Find the value of x. Then, find the measure of RQ. mRP mZRPO = (5x + 15) Given: = (9x + 17), mPQ = (6x - 12), 9x + 17 6x - 12 5x + 15

–0.2(x – 20) = 44 – x
Answer: x=50
Step-by-step explanation:
Use the distributive property to multiply -0.2 by x-20.
-0.2x+4=44-x
Add x to both sides.
-0.2x+4+x=44
Combine -0.2x and x to get 0.8x.
0.8x+4=44
Subtract 4 from both sides.
0.8x=44-4
Subtract 4 from 44 to get 40.
0.8x=40
Divide both sides by 0.8.
x=40/0.8
Expand 40/0.8 approx 50 by multiplying both numerator and the denominator by 10.
X=400/8
Divide 400 by 8 to get 50.
x=50

Answer:
7 square feet per student
Step-by-step explanation:
To find "A per B", divide the quantity of A by the quantity of B. It can help to keep the units with the numbers.
Here, you want area per student, so divide area by students:
area per student = (357 ft²)/(51 students) = 7 ft²/student
The relationship is 7 square feet per student.

Finding slopes of the lines to determine their relationship
1. J(1, 9), K(7, 4), L(8, 13), M(-2, 1)
Slope of JK
m = (4-9)/(7-1) = -5/6Slope of LM
m = (1-13)/(-2-8) = -12/-10 = 6/5These lines are perpendicular as slopes are negative reciprocal
2 J(13, -5), K(2, 6), L(-1, -5), M(-4, -2)
Slope of JK
m = (6-(-5))/(2-13) = 11/(-11) = -1Slope of LM
m = (-1-(-5))/(-4-(-1)) = 4/(-3) = -4/3Lines are neither parallel nor perpendicular
3. J(-10, -7), K(-4, 1), L(-3, 2), M(-6, -2)

After accelerating for 20 seconds, a DeLorean sports car has a wide range of speeds that it can achieve, depending on traction. The distribution of speed follows an approximately normal distribution with a mean of 80 mph and a standard deviation of 7 mph. What percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
Answer:
81.859%
Step-by-step explanation:
We solve the question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 80 mph
σ is the population standard deviation = 7 mph
For x = 66 mph
z = 66 - 80/7
z = -2
Probability value from Z-Table:
P(x = 66) = 0.02275
For x = 87 mph
z = 87 - 80/7
z = 1
Probabilith value from Z-Table:
P(x = 87) = 0.84134
The probability of the trials will give the DeLorean a speed between 66 mph and 87 mph is calculated as:
P(x = 87 mph) - P(x = 66 mph)
0.84134 - 0.02275
= 0.81859
The percentage of the trials will give the DeLorean a speed between 66 mph and 87 mph?
