Answer:
Angle A = 97.5º
Step-by-step explanation:
Supplmentary means 2 angles that equal 180º. So we already have 1 angle, so now all we have to do is subtract 82.5 from 180.
180 - 82.5 = 97.5
Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.
What is an angle?The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360 °.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
Angle A and angle B are supplementary. The measure of angle B is 82.5°.
Then the equation is given as,
∠A + ∠B = 180°
Simplify the equation, then the measure of the angle A will be calculated as,
∠A + 82.5° = 180°
∠A = 180° - 82.5°
∠A = 97.5°
Angle A and angle B are supplementary. Then the measure of the angle A will be 97.5°.

The function shown is reflected across the y-axis to create a new function. Which is true about the domain and range of each function? Both the domain and range change. Both the range and domain stay the same. The domain stays the same, but the range changes. The range stays the same, but the domain changes.
Answer:
its b friends :)
Step-by-step explanation:
If the function shown is reflected across the y-axis create a new function. Both the range and domain stay the same.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that, the function shown is reflected across the y-axis to create a new function. We have to state the domain and range of each function.
The domain and/or range of a function will change when it is transformed. Only the domain will change if the inputs are only transformed. Only the range will change if the transformation only affects the outputs. The domain and range will change if the inputs and outputs are transformed simultaneously.
Thus, if the function shown is reflected across the y-axis creates a new function. Both the range and domain stay the same.

The height of a stack of 12 pennies is 18.24 millimeters. What is the thickness of each penny? Please explain how you got your answer :)
9514 1404 393
Answer:
1.52 mm
Step-by-step explanation:
Let p represent the thickness of one penny. Then a stack of 12 pennies will have a thickness of 12p.
12p = 18.24 mm
p = 18.24 mm/12 = 1.52 mm . . . . divide by the coefficient of p
The thickness of each penny is 1.52 mm.

What is the area of this shape?
units squared
Answer: 19 units squared
Step-by-step explanation:
1) Use Area= 1/2bh to get the area of the two triangles, 15 and 4
2) Add the areas together
Answer:
19 units squared
Step-by-step explanation:
I have attached an image that explains the process.
Essentially we split the shape into 3 triangles, and solve the area of each, and add them up.
The top right triangle is 3 x 5. So A = (3 x 5) / 2 = 7.5
The bottom right triangle is a copy of the top right. So that A = 7.5
The triangle on the left is 4 long and 2 high. So A = (4 x 2) / 2 = 4 units.
Total area is:
7.5 + 7.5 + 4 = 19 units squared.

Answer:
$13.20
Step-by-step explanation:
Working h hours and earning t in tips, your earnings (e) are ...
e = 5.25h +t
Solving for t, we get ...
t = e - 5.25h
Filling in the given values, we have ...
t = 34.20 -5.25(4) = 34.20 -21.00 = 13.20

Step-by-step explanation:
Hope that helps!
An example of two integers that make a zero pair is 6 and -6.
They are additive inverses because they sum up to zero
For two integers to make a zero pair:
They must be equal in magnitudeThey must have opposite signsLet the first number be represented by x
For one to be the additive inverse of the other, the second number must be -x.
x + (-x)
= x - x
= 0

Answer:
-5.9,58%,23/4,5.9
Step-by-step explanation:
-5.9,5.75,5.9,0.58
Answer:
-5.9, 0.58, 5.75, 5.9
Step-by-step explanation:
Begin by writing all four numbers into the same form.
We'll start with -5.9.
Next, 23/4 = 5 3/4 or 5.75
Next: 5.9 stays as such
Finally, 58%, a percentage, changes to 0.58
Then the four numbers are:
-5.9, 5.75, 5.9 and 0.58
-5.9 is the smallest (and is positioned furthest from the origin to the left.
0.58 is the next smaillest; it's positive, whereas -5.9 is negative.
The next two numbers are
5.75 and
5.9
Least to greatest, we have -5.9, 0.58, 5.75, 5.9
