Please help me out with this geometry math assignment I been struggling so hard and I need help can you help me out and it is due today by 1:00pm so please help me I really need to get it done and I be stress and nothing work out only question 13c is hard for me so help me
Answer:
see explanation
Step-by-step explanation:
13 (a)
Given
x + 2y = 3 ( subtract x from both sides )
2y = - x + 3 ( divide all terms by 2 )
y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{1}{2}[/tex]
(b)
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
(c)
The partial equation of the perpendicular line is
y = 2x + b
To find b substitute (1, 4) into the partial equation
4 = 2 + b ⇒ b = 4 - 2 = 2
y = 2x + 2 ← equation of perpendicular line

Answer:
31.4 cm
62.8 cm
Step-by-step explanation:
The radius of the inner circle is 5 cm. The line from the edge of the outer circle to the edge of the inner circle is 5 cm. Assuming that the center of the outer center is the same as the center of the inner circle, the radius of the outer should be 10 cm.
Use the formula for circumference since you have the radius.
Inner circle
C = 2πr
C = 2π(5)
C = 10π
C = 31.4 cm
Outer Circle
C = 2πr
C = 2π(10)
C = 20π
C = 62.8 cm
Some researchers claim there is an association between taking vitamins and gaining weight. They took a random sample of people living in Boston, Massachusetts, and recorded whether they took vitamins and whether they gained weight. The results are shown in the following two-way table:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
If a person is chosen at random, what is the probability that he or she has gained weight, given that he or she takes more than one vitamin per day?
0.42
0.45
0.47
0.50
Answer:
The probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47
Step-by-step explanation:
Has Gained Weight Has Not Gained Weight
Does not take vitamins 52 19
Takes one vitamin per day 35 49
Takes more than one vitamin per day 72 80
We are supposed to find the probability that he or she has gained weight, given that he or she takes more than one vitamin per day
A= he or she has gained weight
B=he or she takes more than one vitamin per day
[tex]P(A|B)=\frac{P(A \cap B)}{P(B)}[/tex]
[tex]A \cap B = 72[/tex]
B = 72+80=152
So,[tex]P(A|B)=\frac{72}{152}=0.47[/tex]
So, Option C is true
Hence the probability that he or she has gained weight, given that he or she takes more than one vitamin per day is 0.47

Mrs. Irvin's kids would like some sandwiches! They can choose from 3 kinds of bread, 2 types of meat, and 4 types of cheeses. How many different sandwich combinations could she make? (Hint: Draw a tree diagram to help figure out the combinations. You could label bread as B1, B2, B3; meat as M1, M2; cheese as C1, C2, C3, C4, etc)
9 sandwich combinations
10 sandwich combinations
24 sandwich combinations
None. They will all end up wanting peanut butter instead and then just feed it to the dog. ;)
Answer:
I don't knoooooooooow
Answer:
24 sandwich combinations
Step-by-step explanation:
To solve this problem, you can do 3x2x4, and you would get 24.
Or, you can do something like this:
1st kind of bread with 1st type of meat and 4 options of cheese = 4 possible combinations
1st kind of bread with 2nd type of meat and 4 options = another 4 possible combinations
Those combinations added together equals 8 combinations. If you multiply this by 3 (3 types of bread), then you would get 24 sandwich combinations, which is the answer.
Hope this helps! :)

It takes 323232 minutes for 888 people to paint 888 walls.
How many minutes does it take 121212 people to paint 121212 walls?
minutes
Answer:
323232÷121212
answer=2.66
Answer:
32 minutes
Step-by-step explanation:
Imagine that each person is assigned one wall, and all 8 people begin painting at the same time.
Since everyone will finish painting their assigned wall after 32 minutes, it takes one person 32 minutes to paint one wall.
If we have 12 people and 12 walls, we can again assign one wall to each person.
Everyone will take 32 minutes to paint their assigned wall.
In other words, it takes 32 minutes for 12 people to paint 12 walls.

Kevin has $4.85 in nickels and dimes. If he has 34 fewer dimes than nickels, how many coins (nickels and dimes) does he have altogether?
A. 74 coins
B. 75 coins
C. 76 coins
D. 77 coins
Answer:
if x = the number of nickles and x-34 = the number of dimes then .05x + .10(x-34) = 4.85 or .15x = 8.25 x = 55
So, nickles = x = 55
dimes = (x-34) = 21
55+ 21 = 76 So, that means your answer is C. 76 coins
Step-by-step explanation:
Answer:
the correct answer is C
Step-by-step explanation:
Set the 34 more nickels aside.
--> pairs of 1 nickel & 1 dime each worth 15 cents & a total of $3.15 ($4.85 - $1.70)
315/15 = 21 pairs
--> 21 dimes and 55 nickels

XThe equation has a steeper slope than the line in the graph.
VThe slope of the line in the graph is -2.
XThe graph and the equation express an equivalent function.
Step-by-step explanation: 1 and 3 got it right on e2020 please mark brainliest
Both lines have a negative slope and The slope of the line in the graph is -2
The equation of a straight line is given by:
y = mx + b;
where m is the slope of the line, b is the y intercept, y,x are variables.
Given that a line goes through (-2, 1) and (0, -3), the equation of this line is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-1=\frac{-3-1}{0-(-2)} (x-(-2))\\\\y-1=-2(x+2)\\\\y-1=-2x-4\\\\y=-2x-3[/tex]
Therefore the slope of the line in the graph is -2
The second line is given by:
[tex]y=-\frac{2}{9} x+2[/tex]
This line has a slope of -2/9
a) Both lines have a negative slope
b) The graph has a steeper slope
c) The slope of the line in the graph is -2
d) The graph and equation do not express an equivalent function because they have different equations

Slopes of Parallel/Perpendicular Lines
Answer:
-1
Step-by-step explanation:
y=-x+5
Parallel lines have same slopes.
The slope of the parallel and perpendicular lines will be -1 and 1, respectively.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given below.
x + y = 5
y = -x + 5
The slope of the equation is a negative one.
The slope of the parallel lines will be the same which is negative 1.
The slope of the perpendicular lines will be the negative inverse of the slope that is 1.

Answer:
4a ) Difference ⇒ $ 63.24,
4b ) 4 children
Step-by-step explanation:
4a ) If the number of children is represented by the value of x, let us substitute a family of 2 children as value of x into this equation we are given;
y = 21.08 * ( 2 ) + 85.15 ⇒ Multiply 21.08 by 2,
y = 42.16 + 85.15 ⇒ Combine like terms,
y = 127.31
If y ⇒ amount spent on grocery's, let us solve for the amount spent on 5 children, and subtract from this amount;
y = 21.08 * ( 5 ) + 85.15 ⇒ Multiply 21.08 by 5,
y = 105.4 + 85.15 ⇒ Combine like terms,
y = 190.55
Difference; 190.55 - 127.31 = 63.24,
Solution; Difference ⇒ $ 63.24
4b ) If the amount is $ 169.47, let us plug it into our given equation provided amount spent on groceries ⇒ y;
169.47 = 21.08x + 85.15 ⇒ Subtract 85.15 from either side of equation,
21.08x = 84.32 ⇒ Divide either side 21.08,
x = 4 children
Solution; 4 children
