Answer:
the anwser is 242
Step-by-step explanation:
I dont see a q anywhere but you would sub p and 9 and do the equation so times 10 and 9 and then distribute 22 or in your calculator jus enter 22(90-79) and you would get 242

Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4

Using the equation S = (n − 2) 180, find the measure for one Interior angle of a decagon (10-sides). Round to one decimal place if necessary.
Answer:
1140
Step-by-step explanation:
A decagon has 10 sides so substitute it like this:
(n-2) x 180
(10-2) x 180
8 x 180= 1140
Edith leaves her home at 11:50 am.
She travels 75 miles at an average speed of 30 mph.
At what time does she finish the journey.

Answer:
2:20 pm
Step-by-step explanation:
30 mph=1 mile every 2 minutes
75 miles x 2 =150 minutes or 2 hours and 30 minutes
11:50 am + 2 hours and 30 minutes = 2:20 pm
What is the value of x for the equation 4x – 2y = 6 if y= -3?
Answer:
x = 0
Step-by-step explanation:
Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:
[tex]4x-2y=6\\2x-y=3[/tex]
Substituting -3 for y:
[tex]2x-(-3)=3\\2x+3=3\\2x=0\\x=0[/tex]

5. (1, 2), (2, 5), (2, 1) (4, 5) No
Step-by-step explanation:
If you see the same x-coordinate more than once in a relation, then that relation is not a function.
1. (1, 3), (2, 5), (2, 7) (4,9) The 2 is used more than once as a x-coordinate. Not a function.

Sara sold 461 tickets for a school play. Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.How many adult tickets and how many student tickets did Sara sell?
Answer:
220 student and 241 adults
Step-by-step explanation:
x+y=461
3x+4y=1624
y=-x+461-----> 3x+4(-x+461)=1624
-x+1844=1624
+x -1624
x=220
3(220)+4y=1624
660+4y=1624
4y=964
y=241
There are 241 adult tickets and 220 student tickets did Sara sell.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Sara sold 461 tickets for a school play.
And, Student tickets cost $3 and adult tickets cost $4. Sara’s sales totaled $1624.
Let number of adult tickets = x
And, Number of student tickets = y
Hence, We get;
⇒ x + y = 461 .. (i)
And, 4x + 3y = 1624 .. (i)
Multiply by 3 in (i);
⇒ 3x + 3y = 1383 .. (iii)
Subtract form (ii);
⇒ x = 241
And, From (i);
⇒ x + y = 461
⇒ 241 + y = 461
⇒ y = 461 - 241
⇒ y = 220
Thus, There are 241 adult tickets and 220 student tickets did Sara sell.

Which graph represents the proportional relationship given by the rule "y is 3 times the value of x"?
Please answer fast less than 5 min
Answer:
The fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Step-by-step explanation:
Given the rule
''y is 3 times the value of x".
It means
y = 3x
comparing with the slope-intercept form of the line equation
y = mx+b
where y is the slope and b is the intercept
so,
The slope of y = 3x will be: m = 3
The y-intercept of y = 3x will be: b = 0
CHECKING THE 4TH GRAPH (THE RIGHT BOTTOM SIDE)
Taking two points
(0, 0)
(2, 6)
Finding the slope between (0, 0) and (2, 6)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [6 - 0] / [2 - 0]
= 6 / 2
= 3
Thus, the slope of the line = m = 3
We know that the value of y-intercept can be determined by setting x = 0, and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 0
Thus, the y-intercept b = 0
Now, substituting m = 3 and b = 0 in the slope-intercept form of linear function
y = mx+b
y = 3x+0
y = 3x
Therefore, the fourth graph i.e. RIGHT BOTTOM GRAPH is correct which represents the proportional relationship given by the rule y = 3x.
Also, the correct graph is attached below.
Answer:
It's the bottom right graph.

Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the
following probability distribution:
a)
0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the
mean
b)
0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils
c)
0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the
mean
d)
0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils
e)0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils
Answer:
0.82

Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h

B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to

If you can't read my writing, this is the questions:
'Calculate the perimeter of this sector.
Give your answer in terms of pi.'
Answer:
Perimeter of the sector = (36 + 8π) cm.
Step-by-step explanation:
Formula to find the of an arc of the circle is,
Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = central angle formed by the arc
r = radius of the circle
Therefore, length of the arc given in the picture = [tex]\frac{80}{360}(2\pi) (18)[/tex]
= 8π cm
Perimeter of the sector = Sum of all sides of the sector
= Length of radius + length of the arc + length of radius
= 18 + 8π + 18
= (36 + 8π) cm
Perimeter of the sector is (36 + 8π) cm.

4u+3u+21=70 find the value of the variables
Answer:
u=7
Step-by-step explanation:
First, add 4u and 3u because they are like terms.
7u+21=70
Second, subtract 21 from both sides.
7u=49
Finally, to isolate the variable divide 7 from both sides.
u=7

What is the image of A(1,-3)?
use the following transformations with each question:
Reflection across the x-axis
Reflection across the y-axis
Reflection across the y = x
Reflection across the y = -x
Step-by-step explanation:
Given A(1 , -3)
Reflection across the x -axis
= A'( 1 , 3)
Reflection across the y-axis
= A'( -1 , - 3)
Reflection across the y = x
= A' ( -3 , 1)
Reflection across the y = - x
=A'( 3 , - 1)
