Is this supplementary or congruent?
Answer:
supplementary
Step-by-step explanation:
we have,
2x+96=180
=> 2x = 180- 96
=> 2x = 82
now,
82 + 96 = 180
so they are supplementary angles

Answer:
A)
Step-by-step explanation:
A systems of equations that are 2 completely separate lines will have 1 solution.
A systems of equations that are the same line will have infinite amount of solutions.
A systems of equation that have parallel lines will have no solution.
We see that B, C, and D are all 2 completely separate lines with their own slope and y-intercept. Therefore, they will have 1 solution.
A is our answer because we see that they have the same slope but different y-intercepts. This means that they are parallel lines and will never intersect each other, thus providing us with no solution.

Can someone find The volume of the shaded portion of the cylinder??????????????????????? I have attached the picture
Step-by-step explanation:
Area of circle = πr², π = 22/7 or 355/133. Here it is said to use '3.14'. I will use the same.
Volume = cross-section area * height
Cross-section area of bigger one = π(3m)²
Volume = π(3m)² * height
= 9π * 5 m³ = 45π m³
Cross-section area of smaller one= π(1m)²
Volume = π(1m)² * height
= π * 5 m³ = 5π m³
Since a large part(cylinder of 1 m is not here):
Required volume = total volume - volume of smaller circle(cylinder)
= 45π - 5π m³
= 40π m³ = 40(3.14) m³
= 125.6 m³
The midpoints of a GH is M(5, 7). One endpoint is H(12, -9). Find the coordinates of endpoint G. Find the distance between the endpoints GH.
Answer:
Step-by-step explanation:
(x+12/2,y-9/2)=(5,7)
x+12=10,y-9=14
x=-2,y=23
The coordinates of endpoint G is (-2, 23) if the midpoints of a GH is M(5, 7). One endpoint is H(12, -9).
What is an ordered double?It is defined as a representation of coordinates in a two-dimensional coordinate plane. It has a list of two elements in it, such as (x, y).
[tex]\rm Area = |\dfrac{(x_1y_2-y_1x_2)+(x_2y_3-y_2x_3)....+(x_ny_1-y_nx_1)}{2}|[/tex]
It is given that:
The midpoint of a GH is M(5, 7). One endpoint is H(12, -9).
The coordinates of endpoint G (x, y)
Using mid-point theorem:
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division.
(x + 12)/2 = 5
x + 12 = 10
x = 10 - 12
x = -2
(y -9)/2 = 7
y - 9 = 14
y = 14 + 9
y = 23
Thus, the coordinates of endpoint G is (-2, 23) if the midpoints of a GH is M(5, 7). One endpoint is H(12, -9).

Amanda charges $20 fee for babysitting plus an additional $5 per hour. The Wilson family paid the babysitter a total of $35 for a night of babysitting. Which equation could be used to determine h, the number of hours Amanda was babysitting for the Wilson family?
Answer:
the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
Amanda babysitted for 3 hours
Step-by-step explanation:
From the question, we know that:
Amanda charges $20 fee for babysitting plus an additional $5 per hour.
Let the number of hours she babysits be represented by x
This is represented by the equation:
$20 + $5× x
= 20 + 5x
We are also told:
The Wilson family paid the babysitter a total of $35 for a night of babysitting.
Hence the equation that can be used to determine how many hours Amanda babysitted for the family =
20 + 5x = 35
5x = 35 - 20
5x = 15
x = 15/5
x = 3 hours
Therefore, Amanda babysitted for 2 hours

Answer:
The ratio of cups of mixed nuts to cups of granola is /First, we need to get the total number of granola cups. This can be done by adding all the components' cups as follows:
number of granola cups = 6 + 2 + 0.5 + 1 + 1 + 0.5
number of granola cups = 11 cups
Now, we are given that:
number of cups of mixed nuts is 2 cups
To get the ratio between the cups of mixed nuts and total granola cups, we will simply divide the two quantities as follows:
Hope this helps :)
Step-by-step explanation:
Granola is a munchable snack that is prepared using various kinds of nuts, seeds, and sometimes a binding agent such as honey is used in the preparation of granola.
In the question above, we are giving the ingredients and quantities which is used in the preparation of granola
6 cups rolled oats, 2 cups mixed nuts, 1 /2 cup sesame seed, 1 cup dried cranberries, 1 cup dried unsweetened coconut, 1 /2 cup honey.
Step 1
We would be adding up the ingredients to find the total number of cups
6 + 2 + + 1 + 1 + = 11 cups
The total number of cups = 11 cups
Step 2
The cups of mixed nuts given in the question = 2 cups
The total number of cups of granola is given = 11 cups
Therefore, the ratio of cups of mixed nuts to cups of granola is 2 : 11

The smaller triangle is dilated to create the larger triangle. The center
of dilation is plotted, but not labeled.
Answer:
Point D is the point of dilation.
Step-by-step explanation:
If the smaller triangle A'B'C' is dilated to form a larger triangle ABC by the dilation about point D,
Ratio of the DA and DA' will be equal to the ratio of DB and DB'.
Length of DA = 3 units
Length of DA' = 1 unit
Coordinates of D → (3, 0)
Coordinates of B → (9, 3)
Coordinates of B' → (5, 1)
Use the formula of distance between the two points to find find the length of DB and DB'
Length of DB = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}=\sqrt{(3-0)^2+(9-3)^2}[/tex]
[tex]=\sqrt{45}[/tex]
[tex]=3\sqrt{5}[/tex]
Length of DB' = [tex]\sqrt{(5-3)^2+(1-0)^2}[/tex]
[tex]=\sqrt{5}[/tex]
Ratio of DB and DB' = [tex]\frac{3\sqrt{5} }{\sqrt{5} } =3:1[/tex]
Ratio of DA and DA' = 3 : 1
Since, [tex]\frac{DA}{DA'}=\frac{DB}{DB'}[/tex]
Therefore, smaller triangle is dilated by a scale factor of 3 to form the bigger triangle about the point D.
If PQ = 20 and QR = 22, then find the length of PR.
Answer: 44

Answer:
107.25 metres.
Step-by-step explanation:
diameter of circle = 150m,
so,
radius = 75 m
perimeter of semi circle
= pi × r
= 3.14 × 75
= 235.5 m
perimeter of rectangle
= 2 × (l+b)
= 2 × (150 + 75)
= 450 m
perimeter of shaded region
= perimeter of rectangle - perimeter of semi circle/2
= 450 - 235.5/2
=107.25 metres

5. If the measure of angle 4 is 135 degrees, what is the measure
of angle 5?
Answer:
Remember that if two angles are supplementary, then the sum of their measures is 180°. So if the measure of an angle is 135 degrees. What is the measure of its supplement?
If the measure of an angle is 135°,
then the measure of its supplement is 45°.
We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 135 or 45°

In preparation for an earnings report, a large retailer wants to estimate p = the proportion of annual sales that occur during the months of November and December. A SRS of sales from last year revealed that 37 of the randomly selected sales occurred during the months of November and December while 124 occurred during the rest of the year.
Calculate a 95% confidence interval for p
Answer:
720 I know this because i did this :)
Step-by-step explanation:
The 95% confidence interval for the proportion p is (0.156, 0.302)
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
To calculate a 95% confidence interval for the proportion p, we can use the following formula:
p ± z√(p(1-p)/n)
where p is the sample proportion (37/161), z is the critical value for a 95% confidence level (1.96 for a large sample size), and n is the sample size (161).
Plugging in these values, we get:
p ± z√(p(1-p)/n)
= 0.229 ± 1.96√((0.229)(0.771)/161)
= 0.229 ± 0.073
Therefore, the 95% confidence interval for p is (0.156, 0.302).
