Answer:
43°
Step-by-step explanation:
1. You need to create an equation: 3c+64+5c+82=90°
(Why 90°?)- this is a right triangle as you can see the little square
2. Then combine like terms
8c+146=90°
3. Subtract 146 from both sides
4. 8c=-56
5. Then divide 8 from both sides
C= -7
6. Then plug in -7 in 3c+64 and solve!
7. The final answer is 43

Step-by-step explanation:
22/5 : 6/5
22/5 * 5/6
22/6
11/3
3 4/6
Answer:
11/3 or 3and2/3
Step-by-step explanation:
To change a mixed number into a fraction, you multiply the whole number by the denominator and add it to the numerator.
4 and 2/5 = 22/5
1 and 1/5 = 6/5
To divide fractions, flip one upside down and then multiply top by top, bottom by bottom
(22/5) / (6/5) = (22/5) x (5/6) = (22x5)/(5x6) = 110/20 = 11/3 or 3and2/3

Solve each equation.
16x=176
Answer:
x = 11
Step-by-step explanation:
16x = 176 is the problem
You bring the 16 over the the other side.
The equation changed.
x = 176 ? 16. You don't no the operation.
If the other side is number + variable,
it equals to division cause division is
the reverse operation.
That means, the equation changes again!
x = 176/16 Its easier to reduce cause its a
2+ number one.
176/16 reduced is 11

There are 38 students involved in planning the homecoming parade. Of these students,
15 are boys and 23 are girls. If three members are selected to lead the parade, find the
probability that all three are girls.
Answer:
60.5% chance
Step-by-step explanation:
it is 23/38, since there are 23 girls and 38 ppl in total
If three members are selected to lead the parade, 23/38 is the probability that all three are girls.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
The number of students involved in planning the homecoming parade are thirty eight 38.
Among these thirty eight students, there are fifteen number of boys 15 and Twenty three number of girls (23).
Given a condition that If three members are selected to lead the parade,
We need to find the probability of all three girls.
The number of students =P(B)=38
The number of girls=P(A)=23
The probability of all three girls is P(A)/P(B)
23/38
Hence 23/38 is the probability that all three are girls.

Select the table that represents a linear function. (Graph them if necessary.)
Answer:
table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.
Step-by-step explanation:
Given the table B values
x y
0 11
1 8
2 5
3 2
As the equation for the linear function
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
As the y-intercept can be obtained by setting x=0
From the table, it is clear that when the value of x=0, then the value of
y=11.
so (0, 11) is the y-intercept.
Also taking two points (0, 11) and (1, 8) to find the slope
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:11\right),\:\left(x_2,\:y_2\right)=\left(1,\:8\right)[/tex]
[tex]m=\frac{8-11}{1-0}[/tex]
[tex]m=-3[/tex]
so substituting the value m=-3 and the point (1, 8) in the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-8=-3\left(x-1\right)[/tex]
[tex]y-8=-3x+3[/tex]
[tex]y=-3x+3+8[/tex]
[tex]y=-3x+11[/tex]
comparing the equation with the slope-intercept form of linear equation
[tex]y=mx+b[/tex]
[tex]y=-3x+11[/tex]
here
m=slope=-3b=y-intercept=11Therefore, table B represents the linear equation which is:
[tex]y=-3x+11[/tex]
The graph of the linear function is also attached below.

But, to find the relative frequencies you will have to find the total number of responses, which is 143.
Then you will go to each box and divide the number given by the total number of response. I will show you each box below:
[tex]\frac{62}{143} = .43\\\\\frac{32}{143} = .22\\\\\frac{29}{143} = .20\\\\\frac{20}{143} = .14[/tex]

Identify a segment skew to AB using the figure
Answer:
EH
Step-by-step explanation:
Skew lines are lines that do not intersect (touch) or are parallel!
A line segment skew to AB is EF. Therefore, option EF is the correct answer.
We need to identify a segment skew to AB.
What are skew lines?Skew lines are a pair of lines that are non-intersecting, non-parallel, and non-coplanar. This implies that skew lines can never intersect and are not parallel to each other. For lines to exist in two dimensions or in the same plane, they can either be intersecting or parallel.
From the given figure, line EF is skew line to AB.
A line segment skew to AB is EF. Therefore, option EF is the correct answer.

Steven earns extra money babysitting he charges $33 for 4 hours and $57.75 for 7 hours entering an equation to represent the relationship let x represent the number of hours Stephen babysits and let y represent the amount he charges the equation is y =
Answer:
y = 8.25x
Step-by-step explanation:
Linear Modeling
Some events can be modeled as linear functions. If a situation comes where a linear model is suitable, then we need two sample points to make the model and predict unknown behaviors.
The linear function can be expressed in the slope-intercept format:
[tex]y=mx+b[/tex]
The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:
[tex]\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Let's use linear modeling to represent Steven's earnings he makes babysitting. Call y the money he charges by x hours of work.
We know he charges y1=$33 for x1=4 hours, and y2=$57.75 for x2=7 hours. The ordered pairs are (4,33) and ( 7, 57.75)
Computing the equation of the line we have:
[tex]\displaystyle y-33=\frac{57.75-33}{7-4}(x-4)[/tex]
Operating:
[tex]\displaystyle y-33=\frac{24.75}{3}(x-4)[/tex]
[tex]y - 33 = 8.25( x - 4 )[/tex]
[tex]y = 8.25x - 33 + 33[/tex]
y = 8.25x
There is a proportional relationship.
