Mabel measured an angle on her math worksheet with her protractor. The angle measured 163°. If she were to draw an angle which was supplementary to the angle on her worksheet, what should that new angle measure?
Two supplementary angles equal 180 degrees when added together.
180 - 163 = 17
the other angle would be 17 degrees

What is a function?A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Here no matter what x is, y will always be positive, because the absolute value of x-5 will always be positive. The smallest value that y can be is when x is 5, because then the absolute value of x-5 is 0, and then y is 2.
Therefore, the correct answer will be option B. The y-values are all greater than or equal to 2.

Simplify 6 plus the square root of negative 80.
The given statement can be written as:
6+√-80
To solve √-80 re-write -80 as -1 * 80
Now √-80 =√-1 * 80
Now we can write it as:
6+ √-1 * √80
We know that √-1 = i
Thus it becomes:
6+ i√80
Now find the square root of 80
80 does not have a perfect square root
Its square root can be found as 80 = 4*4*5
Then,
6+i√4*4*5
Notice that 4 makes a pair.. So we will write it outside the square root
6+1*4√5
We will write it as:
6+4i√5
Thus the correct option is 6 plus 4 i times the square root of 5....

Sadie is 3 years older than Kareem, and Kareem is twice as old as Nadra. The sum of their ages is 33.
A student used the steps below to find each person’s age.
Step 1 Write an equation, letting x represent Kareem’s age:
(x + 3) + x + 2 x = 33
Step 2 Solve the equation:
(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 and one-half.
Step 3 Sadie is 10 and one-half, Kareem is 7 and one-half, and Nadra is 3 and three-fourths.
Which corrects the student’s first error?
Answer:
Step 1-Write an equation, letting x represent Kareem’s age:
(x + 3) + x + 2 x = 33
Step 2-Solve the equation:
(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.
Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.
Which corrects the student’s first error?
1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.
2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.
3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.
4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.

⇒ (2)(7) = 4 + 18⇒ 14 = 22 (False)Option C)
Assuming that (–2)(7) and 18 + (–4) are equal.

⇒ (-2)(7) = 18 + (-4)⇒ (-)(2)(7) = 18 + (-4)⇒ -14 = 18 + (-4)Using the property [x + (-a) = x - a]:
⇒ -14 = 18 + (-4)⇒ -14 = 18 - 4⇒ -14 = 14 (False)Option D)
Assuming that (2)(-7) and 4 - 18 are equal.
⇒ (2)(-7) = 4 - 18Using the property [-x × y = -xy]:
⇒ (-)(2)(7) = 4 - 18⇒ -14 = 4 - 18⇒ -14 = -14 (True)Therefore, Option D is correct.

Which of these intersections of a plane and a three dimensional figure result in a triangular cross section
Answer:
top right one
Step-by-step explanation:
Top left one makes a square
bottom left one makes a circle
top right one makes a triangle
bottom right one makes a circle
The intersection of a plane and a three-dimensional figure results in a triangular cross-section is a triangular pyramid.
What is a cross-section?A solid's cross-section is a plane figure formed when the solid intersects another plane. As a result, the cross-section of an object is an infinitesimal "slice" of a solid, and it can vary depending on how the slicing plane is oriented. A sphere's cross-section is always a disk, although a cube's cross-section can be square, hexagonal, or another shape.
In these types of three-dimensional geometrical problems imagination of the figures is very crucial.
Now, Think of the plane as a very very thin sheet cutting a triangular pyramid parallel to its base will have exactly the same cross-section as its base and we know a triangular pyramid has a triangular base.

Step-by-step explanation:
Given:
A flower vase is in the shape of a cylinder and has a diameter of 5 inches and a height of 7 inches.
To Find:
which equation could be used to determine the volume, in cubic inches, of the vase?
Solve:
Formula for cylinder volume: Volume = πr²h
Where,
h represents the height of the cylinder
r represents the radius of the cylinder.
π is a constant whose value is 3.14
Knowing that:
Diameter = 5 in
Height = 7 in
Radius = 2.5 {Radius is half of diameter so 5/2 = 2.5}
Thus, a equation could be use is:
V = π(2.5)²(7)

How many yards are equivalent to 38 feet? 1 yard = 3 feet
Answer:
13 yards
Step-by-step explanation:
38/3 => 12.6667 yards which would be closest to 13 yards
The formula is to divide the lenght value by 3.
The number 38 feet is equal to 12.67 yards.
We have to give that,
To change 38 feet into yards.
Since we know that,
1 yard = 3 feet
1 feet = 1/3 yards
Hence, change 38 feet into yards as,
1 feet = 1/3 yards
38 feet = 38/3 yards
38 feet = 12.67 yards

A maple tree is 6 meters tall. Its shadow is 8 meters long. Close by, there is a streetlamp
that is 9 meters tall. How long is the streetlamp's shadow?
Write your answer as a whole number or a decimal. Do not round.
meters
Answer:
12 meters
Step-by-step explanation:
The assumption regarding shadow lengths is that they are proportional to height at any given place and time.
__
Here, the streetlamp is 9/6 = 3/2 times as tall as the tree, so we expect its shadow to be 3/2 times the length of the tree's shadow.
(3/2)(8 m) = 12 m
The streetlamp's shadow is 12 meters long.
