In order to solve her final math problem Tina must use the additive inverse. If -16 - (-9) is her problem, what should she do?
Answer:
-7
Step-by-step explanation:
Given data
Tina's problem is
-16 - (-9)
Firstly let her open up the bracket
Note - * -= +
-16+9
Secondly, Rearrange
9-16= -7
Hence the answer is -7

Two mechanics worked on a car. The first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. Together they charged a total of $2475 . What was the rate charged per hour by each mechanic if the sum of the two rates was $200 per hour?
Answer:
1st: 105/h
2nd: 95/h
Step-by-step explanation:
10A+15B=2475 (1)
A+B=200 |*10 => 10A+10B=2000 (2)
From (1) - (2), we have 5B=475, so B=95
then A+95=200 so A is 105
The ages of eight different students in a college math class were used to make the box plot shown above. Which of the following numbers below is the median of the ages?

C. 22.5
D. 24.5
I don't see how to do this...............................
Step-by-step explanation:
So visually youre given the function
for h(-4) it can also be written as h(-4) = y
what do you get for y when you substitute - 4 for x?
All you have to do is trace the line until you get to x=-4 and then find the y that corresponds to it (looks like around y= - 1)
for the other one h(x) = - 5
what do you get for x when you substitute - 5 for y?
what you do is similar, trace the line along the y-axis and see what x-value you get for y =-5
Answer:
3 and x = 0
Step-by-step explanation:
To find the value of h(- 4)
Locate x = - 4 on the x- axis, go vertically up to meet the graph at (- 4, 3 )
Then the value of h(- 4) = 3
For h(x) = - 5
Locate y = - 5 on the y- axis. This is the point (0, - 5)
then the value of x for which h(x) = - 5 is x = 0
Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?
Answer: 15 units
Step-by-step explanation:
Given
The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]
The length of the line segment is given by the distance formula i.e.
[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]
Insert the values,
[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]
Therefore, the length of line segment TU is 15 units
Which statement about 214° is correct?
O A. tan 214° < 0
O B. sin 214° < 0
O C. cos 214° > 0
Answer:
B.
Step-by-step explanation:
214 degree terminates in the 3rd quadrant.
Sine and cosines are both negative there.
This means that sin(214)<0 and cos(214)<0.
If sine and cosine are both negative and since tangent is the quotient of them, then tangent is positive, or tan(214)>0.

The angle measurements in the diagram are represented by the following expressions
ZA = 8r+6
B = 4.1 +38
Solve for x and then find the measure of B:
_B =
answer:
∠B = 70°
step-by-step explanation:
as you can see, the angle are alternate exterior anglestherefore, they are EQUALwe can set them equal to each and solve for x first∠A = ∠B
8x + 6 = 4x + 38
4x + 6 = 38
4x = 32
x = 8
now, we will plug in x in the expression for B to find B4(8) + 38
32 + 38
= 70
therefore, ∠B = 70° and x = 8The measure of an angle is 2.8.what is the measure of its complementary angle
Answer:
87.2º
Step-by-step explanation:
Complimentary angles total 90º
c + 2.8 = 90
c = 90 - 2.8
c = 87.2º
Answer:
87.2°Step-by-step explanation:
When angles are complementary, it means that they both add up to 90°.
In this case, one of the angles measures 2.8°.
So, to find the other one, we subtract 2.8 from 90.
90 - 2.8 = 87.2
The measure of the complementary angle is 87.2°

Answer:
A
Step-by-step explanation:
Use the graph to answer the following questions. image Activity 1 of 2 Part A: Is the relationship between the distance traveled and the time shown in the graph proportional? A. The relationship is proportional because the ratio of the variables is constant. B. The relationship is not proportional because the graph passes through the origin (0, 0). C. The relationship is proportional because the graph goes up by 5 every time. D. The relationship is not proportional because time increases by 2 and distance traveled increases by 5.
