Answer:
1) b= 39.5
2) c= 3.6
3) a=19
Step-by-step explanation:
Use the Pythagorean Theorem to find the missing side length.
"C" is the hypotenuse. Pythagorean Theorem: a^2+b^2=c^2
1) 11^2+b^2=c^41
121+b^2=1681
121-121+b^2=1681-121
b^2=1560
b= 39.5
2) 2^2+3^2=c^2
4+9=c^2
13=c^2
c= 3.6
3) a^2+9^2=21^2
a^2+81=441
a^2+81-81=441-81
a^2=360
a=19

Show how to rewrite 1/5 with the denominator 10
Answers
The denominator is the bottom number.
To change the 5 to 10, you would multiply 5 by 2: 5 x 2 = 10
Because you multiplied the 5 by 2, you also need to multiply the numerator ( top number) by the same amount.
1 x 2 = 2
So 1/5 = 2/10
The answer is 2/10

The sum of two numbers is 25. Twice the first number minus the second is 6. Find the numbers.
Answers
Answer:
Step-by-step explanation:
x + y = 25
2x - y = 6 Solve for y in this the second equation. Add y to both sides
2x = 6 + y The ys on the left cancel. Subtract 6 from both sides.
2x - 6 = y
Put this value of y into the first equation
x + y = 25
x + 2x - 6 = 25 Combine on the left
3x - 6 = 25 Add 6 to both sides.
3x = 25 + 6 Combine the right
3x = 31 Divide by 3
x = 31 / 3
x = 10.333333
x + y = 25
10.33333 + y = 25 Subtract 10.33333
y = 25 - 10.333333
y = 14.666666
x + y = 25
10.33333 + 14.66666
25 approximately.
2x - y = 6
2*10.33333 - 14.66666
20.66666 - 14.66666
6
You should note that those numbers are repeating decimals

The solution is given below:
Step-by-step explanation:
The computation is shown below:
= 19 + 7 divided by 2 - 5
= (19 + 7) ÷ (2) - 5

In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Hudson sets up a website where players can buy and sell these costumes online. Information about the number of people who visited the website and the number of costumes purchased in a single day is listed below.
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Answers
Answer:
62%
Step-by-step explanation:
Given the information :
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Probability that next person will purchase no custome:
Probability = no of successes / total number of trials
Total number of trials :
(purchase no custome + purchase exactly one + purchase more than one)
= (224 + 103 + 32) = 359
Hence, Probability that next person will purchase no custome:
= 224 / 359
As a percentage :
(224 / 359) * 100%
= 0.6239554 * 100%
= 62.39 %
= 62% ( nearest whole percent)

The line CD passes through the points C (2.-1) and D (1, 1). Which of the
following represents the equation of the line in Point-Slope Form?*
Answers
Answer:
The equation of the line in Point-Slope Form will be:
[tex]y + 1 = -2(x - 2)[/tex]
Also, check the attached graph below.
Step-by-step explanation:
Given the points
C(2, -1)D(1, 1)Determining the slope between the points C (2.-1) and D (1, 1).
(x₁, y₁) = (2, -1) (x₂, y₂) = (1, 1)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [1 - (-1)] / [1 - 2]
= [1+1] / [-1]
= [2] / [-1]
= -2
Thus, the slope of the line = m = -2
The point-slope form of the line equation is defined as
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
(x₁, y₁) = (2, -1)m = -2substituting the values m = -2 and the point (x₁, y₁) = (2, -1) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - (-1) = -2 (x - 2)[/tex]
[tex]y + 1 = -2(x - 2)[/tex]
Therefore, the equation of the line in Point-Slope Form will be:
[tex]y + 1 = -2(x - 2)[/tex]
Also, check the attached graph below.

3. Maria's dinner bill is $13.53 after tax. If she wants to leave a 15% tip.
what will the total cost of the dinner be?
Answers
Answer:
$15.56
Step-by-step explanation:
So start by doing a 10% tip, because you just move the decimal place over by 1, so $1.35, and then divide that by 2 to get 5% which is .68, and add them to get 2.03. You can get the same answer by multiplying 0.15 to 13.53. 13.53 + 2.03 is 15.56. Hope this helped and have an awesome day!

Michelle wants to make a long-term investment. She wants to triple an initial investment of
$2,000. If she invests at a simple interest rate of 12% per year, approximately how long will it
take her principal to triple?
Answers
Answer:
It will take approximately 17 years
Step-by-step explanation:
Let the initial investment be x
The investment plus the principal yields 3x
The interest is thus 3x-x = 2x
Formula for simple interest is;
I = PRT/100
R is rate = 12%
T is time = ?
x =$2,000 which is the principal
2x = x * 12 * T/100
2 = 12t/100
12t = 200
t = 200/12
t = 16.67 which is approximately 17 years

(A) 5x2 + 3y =32 (B) 3r? + 5y = 32 (C) 5x° - 3y2 = 32 (D) 3x* + 5y? + 32 = 0
Answers
Equation of the ellipse = 3x² + 5y² = 32
Step-by-step explanation:Given:The centre of the ellipse is at the origin and the X axis is the major axisIt passes through the points (-3, 1) and (2, -2)To Find:The equation of the ellipseSolution:The equation of an ellipse is given by,
[tex]\sf \dfrac{x^2}{a^2} +\dfrac{y^2}{b^2} =1[/tex]
Given that the ellipse passes through the point (-3, 1)
Hence,
[tex]\sf \dfrac{(-3)^2}{a^2} +\dfrac{1^2}{b^2} =1[/tex]
Cross multiplying we get,
9b² + a² = 1 ²× a²b²a²b² = 9b² + a²Multiply by 4 on both sides,
4a²b² = 36b² + 4a²------(1)Also by given the ellipse passes through the point (2, -2)
Substituting this,
[tex]\sf \dfrac{2^2}{a^2} +\dfrac{(-2)^2}{b^2} =1[/tex]
Cross multiply,
4b² + 4a² = 1 × a²b²a²b² = 4b² + 4a²-------(2)Subtracting equations 2 and 1,
3a²b² = 32b²3a² = 32a² = 32/3----(3)Substituting in 2,
32/3 × b² = 4b² + 4 × 32/332/3 b² = 4b² + 128/332/3 b² = (12b² + 128)/332b² = 12b² + 12820b² = 128b² = 128/20 = 32/5Substituting the values in the equation for ellipse,
[tex]\sf \dfrac{x^2}{32/3} +\dfrac{y^2}{32/5} =1[/tex]
[tex]\sf \dfrac{3x^2}{32} +\dfrac{5y^2}{32} =1[/tex]
Multiplying whole equation by 32 we get,
3x² + 5y² = 32
Hence equation of the ellipse is 3x² + 5y² = 32
