Answer:
Solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]
Step-by-step explanation:
13 squared plus b2 equals 18 squared. What is the answer?
We can write it as:
[tex](13)^2+(b)^2=(18)^2[/tex]
Now, solving and find value of b
We know that 13² = 169
and 18² = 324
Putting values:
[tex](13)^2+(b)^2=(18)^2\\169+b^2=324[/tex]
Subtract 169 on both sides
[tex]169+b^2-169=324-169\\b^2=155[/tex]
Now, taking square root on both sides
[tex]\sqrt{b^2}=\sqrt{155}\\b=\pm\sqrt{155}\\b=\sqrt{155},b=-\sqrt{155}[/tex]
So, solving [tex](13)^2+(b)^2=(18)^2[/tex] we get [tex]\mathbf{b=\sqrt{155},b=-\sqrt{155}}[/tex]

Let y=[ 3 1 ]y=
[3
1] and u=[ 8 6 ]u=
[8
6].
Compute the distance from y to the line through u and the origin.
Answer:
2√5
Step-by-step explanation:
Given the coordinates y(3,1) and u(8,6)
We are to find the distance between the two coordinates
Using the formula:
D = √(x2-x1)²+(y2-y1)²
D = √(8-3)²+(6-1)²
yu = √(5)²+(5)²
yu = √25+25
yu = √50
yu = 2√5
Hence the distance between the two coordinates is 2√5

Steve sold 252 fruit basket for a school fundraiser. Evie aold 25 fruit baskets for each 100 baskets that steve sold. How many fruit baskets did evie sell?
PLEASE NEED HELP AND STEPS
Answer: 63
Step-by-step explanation:
From the question, we are informed that Steve sold 252 fruit basket for a school fundraiser while Evie aold 25 fruit baskets for each 100 baskets that Steve sold. This means that Evie sold 25/100 = 1/4 of what Steve sold.
Therefore, the number of fruit baskets sold by Evie will be:
= 1/4 × 252
= 63
Suppose that Dr. Vergara makes a free throw with probability 0.8 and, independently, Dr. Agor makes a free throw with probability 0.4. They each attempt one free throw. (a) Given that only one of them made a free throw, what is the probability that Dr. Agor made his free throw
Answer:
The probability that Dr. Agor made his free throw is 40%.
Step-by-step explanation:
Given the fact that Dr. Agor usually converts his free throws with a probability of 0.4, to determine the percentage of probability that he will convert his free throw, the following calculation has to be performed:
0.4 x 100 x 1 = X
40 x 1 = X
40 = X
Therefore, Dr. Agor has a 40% chance of making his free throw.
Answer:
40%

Hugh made a recipe that yields 8 and 1 over 2 cups. If each serving is 1 over 4 cup, which expression will help Hugh determine the number of servings his recipe will yield? (1 point) 8 and 1 over 2 ⋅ 1 over 4 8 and 1 over 2 + 1 over 4 8 and 1 over 2 - 1 over 4 8 and 1 over 2 ÷ 1 over 4
Answer: It says 25 points brat but whatever.
Step-by-step explanation:→ The number of servings his recipe will yield = (Total recipe yields) ÷ (Each serving) = 8(1/2) ÷ (1/4) = 8 and 1 over 2 ÷ 1 over 4. SO that means it would be option d

The equation c = 2.5t represents the cost, c, for t tickets to the school play. Does a value of 3.5 for t make sense in this situation? Explain your reasoning.
Answer:
No, a value of 3.5 for t does not make any sense because it should be a discrete value.
Step-by-step explanation:
Given equation is:
c = 2.5t
Here,
c = Cost
t = number of tickets
Now,
The value of t cannot be a decimal number but it must be a whole number. Because half ticket cannot be sold.
Hence,
No, a value of 3.5 for t does not make any sense because it should be a discrete value.

Answer:
Linear equation
Step-by-step explanation:
Given

Required
Determine the type of function
We start by checking for linear function
A linear function is such that:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
The above represents the slope
For any pair of coordinate points, the slope must be constant.
We have:
[tex](x_1,y_1) = (-3,-16)[/tex]
[tex](x_2,y_2) = (-2,-13)[/tex]
The slope (m) is:
[tex]m = \frac{-13-(-16)}{-2-(-3)}[/tex]
[tex]m = \frac{-13+16}{-2+3}[/tex]
[tex]m = \frac{3}{1}[/tex]
[tex]m = 3[/tex]
Take another pair:
[tex](x_1,y_1) = (-1,0)[/tex]
[tex](x_2,y_2) = (-10,-7)[/tex]
The slope (m) is:
[tex]m = \frac{-7-(-10)}{0-(-1)}[/tex]
[tex]m = \frac{-7+10}{0+1}[/tex]
[tex]m = \frac{3}{1}[/tex]
[tex]m = 3[/tex]
The slope remains constant
Hence, it is a linear function

As the world I’m heading towards and matching up to is getting bigger
It makes me feel an emptiness somehow
What part it is, even if the shape is maybe like this
Even when myself can’t come to know it
As if solving up the scattered pieces
We are matching up our stories
Inside the empty spot in my heart, there’s a piece called you taking place
I just know it at first glance I saw you
You’re my missing puzzle piece
Finally I solved it
You filled every piece of my heart, even the scarred part of it to the fullest
And somehow, you’ve become my everything
My missing puzzle piece
The fact that I have a flaw,
The truth that I am imperfect All of it makes me feel small
But in between those gaps
We can fill one another with it
So I don’t even realized that it was empty
“Hello, it’s been so long, isn’t it?”
The small piece that I put in my pocket and carry around everywhere
Please be with me so it can be fuller and prettier
After I met you, I’m able to draw a bigger picture
You’re my missing puzzle piece
Finally I solved it
You filled every piece of my heart, even the scarred part of it to the fullest
And somehow, you’ve become my everything
My missing puzzle piece
My missing puzzle piece
More than having everything, Not losing that one thing is more important
Through you, I came to know that
You’re my missing puzzle piece
Very dazzling
It becomes one scene inside the world that I’ve been trying to put together alone
Like the hands that are interlocking tight together,
Because without you, it can’t be completed
So that we won’t lose each other,
My missing puzzle piece

What percent of 20 is 15?
The number after "of" goes on the bottom of the fraction and the number after "is" goes on the top.
PLEASE SOMBODY DO STEP BY STEP .
15 is 75 % of 20
20/15 = 100/75
Answer:
75%
Step-by-step explanation:
Well lets set this up.
You want to find what percent of 20 is 15.
So to do that you can make it a fraction.
The numerator is what is being divided and the denominator is what you want it divided by.
So you want 15 divided by 20
So 15 is numerator
20 is denominator.
[tex]\frac{15}{20}[/tex]
A fraction is basically a division problem so now all you need to do is divide 15 by 20.
If you do that you should get a decimal answer of 0.75
To make a decimal a percentage all you have to do is multiply it by 100.
0.75 * 100
[If you do not have a calculator on you an easy way to do this is look at how many zeros 100 has and move the decimal right that many times]
75
Now just add that percent sign and you have 75% as your answer!
If you need further assistance please don't be afraid to reach out. I hope this helps!
Easy math question, lots of points.
Answer:
LW = 3, KJ = 6, HJ = 5
Step-by-step explanation:
These two triangles are proportionate, as all the angles are the same. Since twp pf the angles from both shapes are equal, the remaining one must also be equal. Since KH = 8 and LG = 4 (both are similar), we can tell that with the similar sides of the small triangle, you multiply by 2 to get the bigger triangle's similar side. If GW = 2.5, HJ = 2.5*2 = 5. LW must be 3 in order to be half of KJ, which is 6.

Find the area of the shape shown below.
Answer:
Total Area = 26.75
Step-by-step explanation:
Remark
The hardest triangle to see is the top one. So we'll start with it.
It has a vertical leg of 3.5 and a horizontal one of 2 + 2 + 5 = 9
Top Triangle Area
Area = 1/2 base * height
Area = 1/2 * 9 * 3.5
Area = 15.75
Triangle on the lower left
Area = 1/2 * 2 * 2
Area = 2
Square on lower middle
Area = 2*2
Area = 4
Triangle on lower right area
Area = 1/2 * 2 * 5
Area = 5
Total Area
Total Area = 5 + 4 + 2 + 15.75
Total Area = 26.75
