Answer:
X = 45
Step-by-step explanation:
x + 135 = 180 {Linear pair}
x = 180 - 135 {Subtract 135 from both sides}
x = 45

Identify the domain of the exponential function shown in the following graph: (2 points)
Answer:
x is greater than or equal to 0.
Step-by-step explanation:
The domain is just your X value. In contrast, the range is your Y value. Since we start at and include 0 on the X axis, we continue forever from there. Therefore, X is greater than or equal to 0.
The resting heart rate of an adult is usually about 60 beats per minute. Complete the chart below and be sure to include comma for thousands.

( 25 point's !!!!!)
Answer:
heart rate for adults ranges from 60 to 100 beats per minute genuinely a lower heart rate is at rest implies more efficient heart functions and better cardiovascular fitness
Step-by-step explanation:
a well-trained athlete might have a normal resting heart rate closer to 60 beats per minute

Colin types his research paper for 3 hours. how many minutes is that?
Answer:
180 minutes
Step-by-step explanation:
60*3=180
Hey there! The answer is:
180 minutes
Explanation:
There are 60 minutes in 1 hour. We know Colin typed his research paper for 3 hours. This means we can multiply 60 minutes by 3 hours and that will give us the number of minutes he spent researching his paper.
60 x 3 = 180
This means Colin typed his research paper for 180 minutes. I hope this answer helped you out, have an amazing day :)

A rectangular schoolyard is to be fenced in using the wall of the school for one side and 500 meters of fencing for the other three sides. The area in square meters of the schoolyard is a function of the length in meters of each of the sides perpendicular to the school wall.
A. Write an expression for A(x) using NO SPACES.
B. What is the area of the schoolyard when x = 100 ?
C. What is a reasonable domain for x in this context?
Answer:
StPart 1) The expression is
Part 2) The area of the schoolyard when x=40 m is A=2,800 m^2
Part 3) The domain is all real numbers greater than zero and less than 75 meters
Step-by-step explanation:
Part 1) Write an expression for A(x)
Let
x -----> the length of the rectangular schoolyard
y ---> the width of the rectangular schoolyard
we know that
The perimeter of the fencing (using the wall of the school for one side) is
so
-----> equation A
The area of the rectangular schoolyard is
---> equation B
substitute equation A in equation B
Convert to function notation
Part 2) What is the area of the schoolyard when x=40?
For x=40 m
substitute in the expression of Part 1) and solve for A
Part 3) What is a reasonable domain for A(x) in this context
we know that
A represent the area of the rectangular schoolyard
x represent the length of of the rectangular schoolyard
we have
This is a vertical parabola open downward
The vertex is a maximum
The x-coordinate of the vertex represent the length for the maximum area
The y-coordinate of the vertex represent the maximum area
The vertex is the point (37.5, 2812.5)
using a graphing tool, see the attached figure
therefore
The maximum area is 2,812.5 m^2
The x-intercepts are x=0 m and x=75 m
The domain for A is the interval -----> (0, 75)
All real numbers greater than zero and less than 75 meters

Pablo can wash 6 cars in 40 minutes at this rate how many cars can Pablo wash in 4 hours
Answer:
16
Step-by-step explanation:
convert 40 minutes to hours
[tex] \frac{40 \: minutes}{1} \times \frac{1 \: hour}{60 \: minutes} = \frac{40}{60} = \frac{2}{3} hour[/tex]
multiply to find the number of cars per hour
[tex] \frac{2}{3} \times \frac{6}{1} = \frac{12}{3} = 4 \: cars \: per \: hour[/tex]
multiply again
[tex]4 \times 4 = 16[/tex]
