Answer:
The sum of the angles is 180°.
We already know that one angle is 90°, and the other one is 38.
so: 180-(90+38)=52°
the exterior angle+52°= 180° (beacuse the form a flat angle)
so x=180-52
so: x=128°.
Answer:
128°
Step-by-step explanation:
We know that,
the exterior angle of a triangle is equal to the sum of the interior opposite angles of a triangle.
Accordingly,
38 + 90 = x
128° = x

Alejandro has a computer support business. He estimates that the cost to run his business can be represented by X = 48 x + 500, where x is the number of customers. He also estimates that his income can be represented by R = 65 x - 145. How many customers he will need in order to break even?
Answers
If Alejandro has a computer support business. The number of customers he will need in order to break even is 38 customers.
How to find the number of customers to break even?Given data:
Cost of business = 48 x + 500
Income = R = 65 x - 145
Let x is the number of customers. He
Income equation
R= 65x- 145
Substitute 48x + 500 for y
48x + 500 = 65x -145
Substract 48x from both side
500 = 17x - 145
Add 145 to each side
645 = 17x
Divide both side by 17x
x =645 /17
x = 37.9
x = 38 customers (Approximately)
Therefore the number or customers is 38 customers.

Write and solve an equality to find the values of x for which the perimeter of the rectangle is less than 128
Answers
The value of x for which the perimeter of the rectangle is less than 128 is x < 30.
How to find the perimeter of a rectangle?The perimeter of a rectangle is the sum of the whole sides of a rectangle. Recall a rectangle is a quadrilateral with opposite sides equal to each other and opposite side parallel to each other.
Therefore, the perimeter of the rectangle is less than 128.
Hence,
perimeter of a rectangle = 2(l + w)
perimeter of a rectangle = 2l + 2w
where
l = side lengthw = widthTherefore,
2(x + 4) + 2x < 128
2x + 8 + 2x < 128
4x + 8 < 128
4x < 128 - 8
4x < 120
Therefore,
x < 30

Graph the line with the equation y = - 3/5x - 3
Answers
we have
y = - 3/5x - 3
To graph the line we need at least two points
so
Find the intercepts
step 1
Find the y-intercept (value of y when the value of x is zero)
For x=0
y=-(3/5)*(0)-3
y=-3
the y intercept is the point (0,-3)
step 2
Find the x-intercept (value of x when the value of y is zero)
For y=0
0=-(3/5)x-3

The equation of a line is the form of

[tex]5x-3y\text{ = (-9)}[/tex]To rewrite this equation in slope-intercept form, we must first find the slope and y-intercept from the equation by rearranging it
[tex]\begin{gathered} 5x+9=3y \\ 3y\text{ = 5x+9} \\ \frac{3y}{3\text{ }}=\frac{5x}{3}+\frac{9}{3} \\ y\text{ = }\frac{5}{3}x+3 \\ \text{From here the slope, m =}\frac{5}{3} \\ \text{and } \\ \text{the y-intercept, c = 3} \end{gathered}[/tex]Hence the required equation is y =(5/3)x +3.

How much you learned about the inverse, converse, and contrapositive of a conditional (if-then) statement, and how this can be applied in real life
Answers
A conditional statement can be written as:
[tex]p\rightarrow q[/tex]An example of this in real life is:
[tex]\text{If it rains then the floor gets wet.}[/tex]In this case:
p = it rains
q = the floor gets wet
The converse of that conditional is:
[tex]\begin{gathered} q\rightarrow p \\ \text{If the floor gets wet then it rains.} \end{gathered}[/tex]Notice that the conditional being true doesn't mean necessarily that its converse is true. For example, every time it rains the floor gets wet can be true, but the floor could get wet for other reasons, so the converse would not be true.
Also, the inverse of that conditional is:
[tex]\begin{gathered} \neg p\rightarrow\neg q \\ \text{If it does not rain then the floor does not get wet.} \end{gathered}[/tex]As we see, the inverse of a true conditional statement is not necessarily true.
And the contrapositive of that conditional statement is:
[tex]\begin{gathered} \neg q\rightarrow\neg p \\ \text{If the floor does not get wet then it does not rain.} \end{gathered}[/tex]Now, the contrapositive of a true conditional statement is always true. Notice that if every time it rains the floor gets wet, the only explanation for the floor not getting wet is that it does not rain.
For the spring picnic, Mr. Jones served 85 hot dogs to 50 people. Mr. Jones expects 68 people at the fall picnic. Which proportion could be used to find how many hot dogs Mr. Jones needs for the fall picnic?

If Mr. Jones served 85 hot dogs to 50 people the proportion of hot dogs is:
[tex]\frac{85}{50}\text{ hot dogs/person}[/tex]If he expects 68 people at the fall picnic, the amount of hot dogs he will need is the number of people multiplied by this proportion:

we have the system
y + z = 6 ------> equation P
5y + 9z = 1 -----> equation Q
i will solve by elimination
step 1
Multiply the equation P by -5
so
(y + z = 6) *-5
-5y-5z=-30
adds equation Q
-5y-5z=-30
5y + 9z = 1

Answers
10220 meters Juanita swim in those 2 weeks.
Given that,
Juanita practiced her swimming for a competition by swimming 0.73 kilometers in the pool every day for two weeks.
We have to find Juanita swam how many meters in those two weeks? 1 km = 1,000 m
First, we multiply the number of days swam by the amount of kilometers swan each day.
0.73×2 week
0.73×14days
10.22
The kilometers are then multiplied by the conversion rate to convert them to meters.
10.22 kilometers multiplied by a 1000 m to m conversion factor results in 10220 m.
Therefore, 10220 meters Juanita swim in those 2 weeks.
