Find the midpoint of the segment with the following endpoints.
(-9,-8) and (-1,2)
Answer:
The midpoint is (-5, -3).
Step-by-step explanation:
Finding the coordinates of the midpoint consists of averaging the x-coordinates of the given points and then doing the same for the y-coordinates.
x coordinate of midpoint = (-9 - 1)/2 = -5
y coordinate = -6/2 = - 3
The midpoint is (-5, -3).

A farmer has 165 feet of fencing material in which to enclose a rectangular grazing area. He wants the
length x to be greater than 50 feet and the width y to be no more than 20 feet.
write a system of inequalities to represent this situation
Answer:
2*x + 2*y ≤ 165 ft
x > 50ft
0ft < y ≤ 20ft
Step-by-step explanation:
For a rectangle with length x and width y, the perimeter of the triangle is:
P = 2*x + 2*y
The perimeter needs to be equal or smaller than the length of fencing that the farmer has, then:
2*x + 2*y ≤ 165 ft
We also know that:
(x strictly larger than 50ft)
x > 50ft
(y can be, at most, 20 ft)
0ft < y ≤ 20ft
(where we added the restriction that y needs to be larger than zero, because we can not have a width equal or smaller than zero)
Then the system of inequalities that represent this situation is:
2*x + 2*y ≤ 165 ft
x > 50ft
0ft < y ≤ 20ft
A line passes through (0, -1.8) and has a slope of -3. Write an equation of the line.
Answer:
y=-3x-1.8
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1.8)=-3(x-0)
y+1.8=-3(x)
y+1.8=-3x
y=-3x-1.8

There are 10 girls and 5 boys in Ms. Sander's class. Each day, she randomly asks one student to take attendance. In 180 school days, which is the best prediction for the number of times that the student will be a girl?
Answer:
120
Step-by-step explanation:
The probability of a girl being picked one day = 10/15 = 2/3
Total number of days = 180
Therefore, the nunber of times it will be a girl = 2/3 x 180 = 2 x 60 = 120

An amusement park charges an entrance fee of $20 and the rides cost $4 each. Suppose you write a function for the total cost for entering the park and riding a. Number of the rides. What is the domain of the function based on the given context?
Answer:
With the information provided, you can say that the total cost is equal to the entrance fee plus the price per ride for the number of rides, which would be:
C(x)=20+4x,where:
x is the number of rides
The domain of the function refers to all the inputs that the function can have and in this case, the domain consists of all real numbers greater than or equal to zero since x refers to the number of rides and it can't have a negative number.

Charlotte needs 16 1/2 yards of fabric to make a quilt. She has one piece of fabric that is 3 1/2 yards and another piece of fabric that is 6 3/4 yards. How many more yards of fabric does Charlotte need to make the quilt?
YOUR ANSWER BETTER NOT HAVE A LINK OR YOU ARENT GETTING POINTS!
Answer:
6 1/4
Step-by-step explanation:
Add up the fabric that she has
3 1/2 + 6 3/4
Get a common denominator
3 2/4 + 6 3/4
9 5/4
9 4/4 + 1/4
10 1/4
Subtract this from the fabric that she needs
16 1/2 - 10 1/4
Get a common denominator
16 2/4 - 10 1/4
6 1/4

Actually Welcome to the concept of Angles.
Here, total angle is 90°.
hence, 90° = x + 57°
so, ==> x = 90° - 57°
x = 33°
hence, x = 33°
Answer:
x=33°
Step-by-step explanation:
90-57=33. Basically, Q is 90°
A spinner with 20 equal-sized sections has 5 red, 10 blue, 3 green, and 2 yellow sections. Ann pays $10 to spin the spinner. If she spins a yellow, she wins $20; if she spins green, she wins $15; otherwise, she loses.She plays the game twice. What is the expected payoff for her games?
Answer:
The expected payoff for Ann is that she loses the game
Step-by-step explanation:
The expected payoff for Ann is that she loses the game, this is because only 5 out of the 20 sections allow Ann to win money, this is only 25% of the spinner. Meaning that 75% of the spinner will cause Ann to lose the game. Rolling two times increases the odds that she will lose the game. Since the greatest probability is that Ann will land on a section that causes her to lose the game, then this is the expected payoff.

Can someone please help me to calculate this? I would really appreciate it. (-2)²(-3)³
Answer:
-108
Step-by-step explanation:
(-2)²(-3)³
When a number has an exponent, it means that the number is being multiplied to itself. For example, in (-2)², it means (-2) multiplied by itself twice since the exponent is 2. And for (-3)³, it means (-3) multiplied by itself 3 times since the exponent is 3.
= (-2)(-2)(-3)(-3)(-3)
Multiply. Remember that two negative numbers multiplied together make a positive number, and a positive and a negative number multiplied together make a negative.
= (4)(-3)(-3)(-3)
= (-12)(-3)(-3)
= (36)(-3)
= -108
Therefore, the answer is -108.

Use a special right triangle to find the value of y. Write as a decimal rounded to the nearest 10th
Given:
The figure of a right angle triangle.
To find:
The value of y.
Solution:
in a right angle triangle,
[tex]\sin \theta=\dfrac{Opposite}{Hypotenuse}[/tex]
In the given right triangle,
[tex]\sin 60^\circ=\dfrac{6}{y}[/tex]
[tex]\dfrac{\sqrt{3}}{2}=\dfrac{6}{y}[/tex]
On cross multiplication, we get
[tex]\sqrt{3}y=12[/tex]
[tex]y=\dfrac{12}{\sqrt{3}}[/tex]
[tex]y=\dfrac{12\sqrt{3}}{3}[/tex]
[tex]y=4\sqrt{3}[/tex]
Therefore, the value of y is [tex]4\sqrt{3}[/tex] units.

Answer:
x = 42,33°
Step-by-step explanation:
3x + 1° + 52° = 180° [angles on a straight line]
3x + 53° = 180°
3x = 180° - 53°
3x = 127°
divide both sides by 3
x = 42,33°
Nancy watches her dad fix a broken chair with a nail and a hammer, but she finds the hammering sound too loud. So, she decides to go back to her room, which is next door. On entering her room, she finds the hammering does not sound as loud. Why does the sound become faint?
Answer:
The sound of hammering becomes fainter as Nancy goes into her room because some of the sound waves are absorbed by the walls. Only part of the sound waves coming from the other room comes into her room, so the hammering sounds quieter.

Students sell 80% of the books at a book slae. They sell 48 books in all. How many books are at the book sale? Show your work.
Answer:
60 books were at the book sale
Step-by-step explanation:
Let
x = total books at the book sale
Percentage of books sold = 80% of x
= 80/100 * x
= 0.8x
Number of books sold = 48
Therefore,
0.8x = 48
Divide both sides by 0.8
0.8x / 0.8 = 48 / 0.8
x = 60 books
x = total books at the book sale = 60 books
Number of books unsold = Total books at the book sale - number of books sold
= 60 - 48
= 12
Number of books unsold = 12 books
Tina paid $6.60 for some $0.15 stamps and some $0.20 stamps. She bought 37 stamps in all. How many of each kind did she buy?
PLS HELP
Answer:
1 set of A= $0.15
1 set of B= $0.20
Total Stamps bought = 37
Total purchase = 37
Let X= Set A of $0.15 each
Y= Set B of $0.20 each
x+y = 37----------X=37-Y
0.15X + 0.20Y = 6.60
0.15(37-Y) + 0.20Y = 6.60
5.55- 0.15Y + 0.20Y =6.60
0.05 Y = 6.60-5. 55
Y=1.05/ 0.05= 21
X= 37-21= 16

Grace, Maci, and Kendra all have a large collection of earrings.
The number of pairs of earrings in Grace’s collection is represented by x.
The number of pairs of earrings in Maci’s collection is three times the number of pairs in Grace’s collection.
Kendra has 4 earrings in her collection.
The total number of pairs of earrings in all three girls’ collections is 52.
How many pairs of earrings are in Maci’s collection?
Answer:
36
Step-by-step explanation:
Kendra has 4 so 52-4 (so it's out of the way) now you have 48
Divide 48 by 3 (leaves you 16). It can't be 16 because you have to add 16 and the sum of 16 x 3. So, go down a few numbers
12 + (12x3) = 48 plus Kendra's 4 is 52
