Five girls in a homeroom class of 20 students have blonde hair. If there are 120 students in the school, how many would you predict are blonde haired girls?
Step-by-step explanation: To find how many girls are blonde-haired, we'll have to subtract.
120 - 20 =
1. Subtract 0 by 0.
0 - 0 = 0
2. Subtract 2 by 2.
2 - 2 = 0
3. Since there isn't a number in the hundred's place, bring the 1 down.
Therefore, your answer is: 100. There are 100 blonde-haired girls.

what is the inverse of f (x) = −(x+1)^2+4
Step-by-step explanation:
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=4−(x+1)2 becomes x=4−(y+1)2.
Now, solve the equation x=4−(y+1)2 for y.

p - 13 = 29
Can anyone help me with this
Answer:
42
Step-by-step explanation:
p - 13 = 29
Add 13 to both sides.
p - 13 + 13 = 29 + 13
p = 42
Answer:
p= 42
Step-by-step explanation:
29 plus 13 equals 42 which leaves p alone so p equals 42

I have to determine whether the sides of the triangle form a pythagorean triple.
Answer:
Step-by-step explanation:
How do you know if side lengths form a Pythagorean triple?
Pythagorean triples may also help us to find the missing side of a right triangle faster. If two sides of a right triangle form part of a triple then we can know the value of the third side without having to calculate using the Pythagorean theorem. From the ratio, we know that it is a Pythagorean triple.

Find the mid segment of GH
Answer:
B. 2
Step-by-step explanation:
Based on the Midsegment of a trapezoid theorem:
GH = (BC + FE)/2
9x - 3 = (19 + (5x + 1))/2) (substitution)
9x - 3 = (20 + 5x)/2
Cross multiply
2(9x - 3) = 20 + 5x
18x - 6 = 20 + 5x
Collect like terms
18x - 5x = 20 + 6
13x = 26
Divide both sides by 13
x = 26/13
x = 2
Write the following in slope-intercept form
12x + 10y = 100
Answer:
I'm learning this too the answer is 12x+10y10
slope-intercept form: y = mx + b
we know what format we need to change the equation to.
subtract 12x to each side to get 10y alone.
12x - 12x + 10y = 100 - 12x
10y = -12x + 100
divide 10 to both sides to get y alone.
10/10y = -12/10x + 100/10
y = -6/5x + 10
y = -6/5x + 10 is your answer. i hope this helpes! let me know if i got something wrong that i need to fix.

9.14 books in 2 boxes; 20 books in 3 boxes.
10.On a monday you swim 12 laps in 30 minutes. On tuesday you swim 15 laps in 45 minutes are these rates porportional? Explain.
Answer and explanation:
1. 15 girls to 6 boys = 15:6
15/6= 5/2
2. 24 players to 3 teams = 24:3
24/3= 8/1=8
3. 48 worksheets to 12 students =48:12
48/12= 4/1
4. 4/7 and 24/35 are not proportional as they do not reduce to same ratio
5. 11/12 and 33/36 are proportional because they reduce to same same ratio(33/36=11/12)
6. 8/24 and 5/15 are proportional beacaue they reduce to same ratio(8/24=5/15=1/3)
7. 3/7 and 12/21 are not proportional because they do not reduce to same ratio(3/7≠12/21)
8. 25 cars in 5 days= 25/5= 5 cars each day. 60 cars in 12 days = 60/12=5 cars each day. Therefore they are proportional.
9. 14 books in 2 boxes= 7 books per box. 20 books in 3 boxes = 20/3= 6.667. Therefore they are not proportional.
10. 12 laps in 30 minutes =12/30=2/5
15 laps in 45 minutes =15/45=1/3. Therefore they are not proportional.

Answer:
It is side angle side
Step-by-step explanation:
The two sides of the triangle are around the angle
The similarity theorem that identifies the given relationship correctly would be:
B). AABC - ADEF by SAS Similarity Theorem
What is SAS Similarity?The SAS similarity Theorem state that in the situation where the ratio shared by the sides of two triangles remains the same and one of their angles stays equal, both the triangles would be similar.
In the given two triangles,
ΔABC and ΔDEF
The ratio of the sides are:
[tex]\frac{BC}{AB} = \frac{EF}{DE}[/tex]
so,
[tex]\frac{5}{15} = \frac{4}{12} = \frac{1}{3}[/tex]
and,
∠B = ∠E = 86°
Since the ratios shared by the two sides are equal in both the given triangles and one angle is equal, the triangles are the same.
Thus,
ΔABC ~ ΔDEF

mZWVA = 106°, m_AVU = 4x + 4,
and mZWVU = 21x + 8. Find x.
What is x?
9514 1404 393
Answer:
x = 6
Step-by-step explanation:
If we assume that ray VA is between VW and VU, then we have ...
∠WVA + ∠AVU = ∠WVU
106° +(4x +4)° = (21x +8)°
102 = 17x . . . . . . . . . . . . . subtract 4x+8

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
If x + 2y = 9 and 3x - y = -8, what is the value of (2x+y)?
Answer:
The value of (2x+y) is 3.
Step-by-step explanation:
First, we have to find the values of x and y.
We have that:
x + 2y = 9, which also means that:
x = 9 - 2y
Replacing into the second equation, to find y:
[tex]3x - y = -8[/tex]
[tex]3(9 - 2y) - y = -8[/tex]
[tex]27 - 6y - y = -8[/tex]
[tex]7y = 35[/tex]
[tex]y = \frac{35}{7}[/tex]
[tex]y = 5[/tex]
Finding x:
[tex]x = 9 - 2y = 9 - 10 = -1[/tex]
What is the value of (2x+y)?
2(-1) + 5 = -2 + 5 = 3

Answer:
the picture is attachedand sorry I can't explain you much about itA bag contains 4 green marbles, 3 red marbles, and 7
blue marbles. One marble is taken from the bag and put
back after checking its color. A second marble is then
taken out. What is the probability that the first is blue
and the second red?
Answer:
3/28
Step-by-step explanation:
There are 14 marbles in the bag. So, the probability of choosing a blue marble is 7/14 or 1/2. Since the first marble is replaced, the bag still has 14 marbles in it. Then the probability of choosing a red marble is 3/14. The probability of choosing the blue, then the red is 1/2 x 3/14 = 3/28
