Step-by-step explanation:
360° ÷ 120° = 3
A = πr²
A = [tex]\frac{22}{7}[/tex] × 42² = 5,544
The area of the sector of a circle is 5,544 ÷ 3 = 1,848 units²
complete the statements below about the graphs of y=-2x and y=x
Answer:
Compared to the graph of y = x, the graph of y = -2x is steeper.
Compared to the graph of y = x, the graph of y = -2x intersects the y-axis at the same point.
Compared to the graph of y = x, the graph of y = x + ⅔ is equally steep.
Compared to the graph of y = x, the graph of y = x + ⅔ intersects the y-axis at a higher point.

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

What is the slope of the line.
Answer:
-4/5
Step-by-step explanation:
The slope of the graph is -4/5. The slope is the change in y over the change in x. The y-value decreases by 4 and the x-value increases by 5. So the slope is -4/5. One visual way to check this is to remember that slopes that are fractions will make the line flatter, while numbers with absolute values greater than 1 make the slope steeper.

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.

Give an example of two integers that make a zero pair. Explain how they are additive inverses.
Answer:
-6+6=0
-10-(-10)=0
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
An example of integers that make a zero pair 6 and -6
6 + (-6)
= 6 - 6
= 0

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.

You work in a restaurant. Your hourly wage is $5.25. One evening you work from 5:30 to 9:30 and make $34.20 altogether. How much do you make in tips that evening?
Your answer
9514 1404 393
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

125 = 5³, and the given expression reduces to
[tex]\left(\sqrt{125}\right)^{\frac13}\cdot\left(\sqrt[3]{125}\right)^{\frac12}=\left(125^{\frac12}\right)^{\frac13}\cdot\left(125^{\frac13}\right)^{\frac12}=125^{\frac16}\cdot125^{\frac16}=125^{\frac13}[/tex]
so it has a value of 5.
Now:
• the first choice is equivalent, since 625 = 25², so
[tex]\dfrac{\sqrt[3]{625}}{5^{\frac13}}=\dfrac{25^{\frac23}}{5^{\frac13}}=\dfrac{5^{\frac43}}{5^{\frac13}}=5[/tex]
• the second choice is not equivalent, since
[tex]5 \cdot 25^{\frac13} = 5 \cdot 5^{\frac23} = 5^{\frac43}[/tex]
• the third choice is also equivalent, since
[tex]\dfrac{\left(\sqrt[4]{5}\right)^7}{125^{\frac14}}=\dfrac{5^{\frac74}}{5^{\frac34}}=5[/tex]
• the fourth choice is also equivalent, since
[tex]\dfrac{5^{\frac12}\cdot25^{\frac13}}{\sqrt[6]{5}}=\dfrac{5^{\frac12}\cdot5^{\frac23}}{5^{\frac16}}=\dfrac{5^{\frac76}}{5^{\frac16}}=5[/tex]
