I don't understand the problem. Can you help me solve it please? I also have an IEP.
Answer:
12
Step-by-step explanation:
The Pythagorean theorem is
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)
a^2 + b^2 = c^2
Substitute the known values
5^2 + b^2 = 13^2
25+b^2 = 169
Subtract 25 from each side
25+b^2-25 =169-25
b^2 = 144
Take the square root of each side
sqrt(b^2) = sqrt(144)
b=12
Answer:
Given:
a = 5c = 13To find:
missing side b
Solution:
Using Pythagorean theorem,
(Hypotenuse² = base² + perpendicular²)
b² = c² - a²
= 13² - 5²
= 169 - 25
= 144
b = √144
= 12

Drew's neighbor pays him $35 to mow
her lawn and she always gives him a 20%
tip. He decides to mow the lawn with his
friend and split the earnings evenly. How
much will each of them make?
Answer:
Step-by-step explanation:
Ok lets find 20% of 35 first.
20% of 35 is just 2 lots of 10%
10% of 35 is 3.5 if we move over the decimal
2 lots of 3.5 is 7
add the tip on
35 + 7 = 42
42 / 2 = 21
They each get $21
good luck mate!

Kant's sister has 150 red marbles and 360 pink marbles and she wants the same number of marbles on each row, what is the least number of rows she can make ?
Answer:
We know that Kant's sister has 150 red marbles and 360 pink marbles.
She separates the marbles in rows, such that each row must have the same number of marbles.
The least number of rows she can make is when she puts N marbles in each row, such that N is the greatest common factor between 150 and 360.
To find the greatest common factor between 150 and 360 we can write them as the product of prime numbers.
150 = 15*10 = (3*5)*(2*5)
360 = 36*10 = (6*6)*(2*5) = (2*3*2*3)*(2*5)
Here we can see that the factors: 2, 3, and 5 appear (at least) one time in each number, this means that the greatest common factor between 150 and 360 is the product of these 3 factors:
GCF = 2*3*5 = 30
This means that we need to make rows with 30 marbles each.
and we will have:
150/30 = 5 rows of red marbles
360/30 = 12 rows of pink marbles.
A total of 5 + 12 = 17 rows.

Would you use the median or mean to describe the center of each data set? Explain your reasoning. Heights of 50 basketball players
Answer:
Median is used to describe the center of the data of heights of 50 basketball players.
Step-by-step explanation:
The median divides the data into two equal parts.
It can be used to describe the center of the data.
The mean gives the average where most data lies.
The advantages of median are
1)it is located even when the values are not capable of quantitative measurements.
2) It is not affected by extreme values > It can be computed even when a frequency distribution involves open end classes like those of income and prices.
3) In a highly skewed distribution median is appropriate average to use.
The disadvantages of the mean are
1) it is greatly affected by extreme values.
2) It sometimes gives fallacious conclusions.
3) In a highly skewed distribution mean is not an appropriate average to use.
4) It cannot be computed even when a frequency distribution involves open end classes like those of income and prices.

At a particular time of a day, a-7-m high flagstaff casts a shadow which is 8.2m long. What is the height the building which cast a shadow 20.5m in length that the same moment
Answer:
17.5m
Step-by-step explanation:
We solve using the formula
Height /Shadow
Height of flag staff = 7m
Shadow of flag staff = 8.2 m
Height of the building = x
Shadow of the building = 20.5
= 7/8.2 = x/20.5
Cross Multiply
8.2x = 7 × 20.5
x = 7 × 20.5/8.2
x = 143.5 / 8.2
x = 17.5m
The height of the building is 17.5 m
A construction worker drops a wrench from a height of 484 feel the function
h =
16x
+ 484 gives the height h of the wrench after a seconds When does the wrench hit the ground?
The wrench hits the ground blank
seconds after it is dropped
Answer:
30.25 seconds
Step-by-step explanation:
If you want to find the time at which the wrench hits the ground, you must recognize that the height of the wrench is 0 feet. If h represents the height, then 0 can be plugged in for h. The equation is now 0=16x+484. You then must subtract 484 from both sides, giving you -484=16x. You then divide both sides by 16 to give you x by itself. -484/16=-30.25. Because this is dealing with time and negative time does not exist, the negative sign on the 30.25 can be neglected.

Colton sold a total of 28 tee shirts and sweatshirts as a fundraiser for his football team. If tee shirts cost 12 dollars each and sweatshirts cost 20 dollars each and he raised a total of 424 dollars how many tee shirts did he sell?
Answer:
11 sweatshirts and 17 t shirts
Step-by-step explanation:
[tex]t + s = 28\\12t = 20s = 424[/tex]
Step one: cancel out one variable. In this one, t.
[tex]-12(t + s = 28)\\-12t -12s =-336[/tex]
Now that we have that, subtract that from the other expression.
[tex]12t + 20s = 424\\-12t -12s = 336[/tex]
You should get:
[tex]8s = 88\\ s = 11[/tex]
Plug s in any expression
[tex]t + 11 = 28[/tex]
You should know where to go from there, I'm lazy :p
Then t = 17

102.4..... you're right
Answer:
the answer is 102.4
Step-by-step explanation:
A statue of George Washington is also in Druid Hill Park. If a girl stands 15 m away from the statue, and places a mirror 12 m from the statue (3 m from her feet), she can see the top of the statue in the mirror. The girl's height is 5.5 ft. How tall is the statue?
Answer:
The statue is 22ft tall.
Step-by-step explanation:
Here we will have two similar triangle rectangles.
One is made between the girl's feet, the mirror, and the girl's eyes.
So in this case the catheti are:
the distance between the girl and the mirror (3 m) and the height of the girl (5.5 ft)
The other triangle rectangle has the vertices:
The mirror, the base of the statue, and the top of the statue.
Such that the catheti of this triangle are the distance between the base of the statue and the mirror (12m) and the height of the statue (we want to know this, let's call this X for the moment).
Because the triangles are similar, this means that there is a proportionality constant between each correspondent side, let's call this k.
Then the distance between the girl and the mirror must be k times the distance between the base of the statue and the mirror:
3m = k*12m
And the height of the girl must be k times the height of the statue.
5.5ft = k*X
You can see that we have different units, this does not matter because k is a dimensionless constant.
With the first equation we can find the value of k
3m = k*12m
3m/12m = k
(3/12) = 1/4 = k
Now we can replace this in the other equation to get:
5.5ft = (1/4)*X
Solving this for X we get:
(5.5ft)*4 = X
22ft = X
The height of the statue is 22ft.
1. Solve for x
4x + 7 - 3 = 4x + 2x - 3
2. Solve for x
2+5x-2x=9x+8x - 4
3. Solve for m.
3+ 4m - 2 + 2m = 5 + 6 - 3m
Step-by-step explanation:
4x+4=6x-3
4=2x-3
7=2x
x=3,5
3x+2=17x-4
2=14x-4
6=14x
x=3/7
6m+1=-3m+11
9m+1=11
9m= 10
m=10/9

Answer:
H = .298
Step-by-step explanation:
First lets plug in 1.5 for R and 16 for Surface area to get the following
2*pi*1.5^2+2*pi*h = 16 We are solving for H or height
Lets simplify this out a bit to get
16 = 14.13+6.28h
Subtract 14.13 from both sides
1.87 = 6.28h
h= .298
To check our answer lets plug the height into the equation
2*pi*1.5^2+2*pi*.298 = 16
Yes the height or H is .298
To check your answer just plug back what you got before into the equation
HEYYYY COULD SOME ONE HELP ME PLEASE !!! :)
Answer:
4²+b² = 5²
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the length of the missing side.
The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse. Algebraically, this is represented as
a²+b² = c²
We have the measure of one leg, 4 in. We also have the measure of the hypotenuse, 5 in. This gives us
4²+b² = 5²
