Answer: 139
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
5x² - x + 9
x = -5
Substitute value into the expression
=5(-5)² - (-5) + 9
Simplify exponents
=5 (25) + 5 + 9

Answer:
pi*z^2*a or "pizza"
Step-by-step explanation:
The dimensions given describe a cylinder, for which the basic volume formula would be base x height.
The base would be a circle, with the radius z as given while the height is a.
The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.
Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a
Side note:
z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".

Answer:
X=64°
Step-by-step explanation:
Solution,
x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.
x+54°-54°=118°-54°
x=64°
Answer:
64 degrees
The Process:
54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.

Step-by-step explanation:
AB represents the largest side of the triangle so in order to solve for that side, use Pythagorean Theorem.
Pythagorean Theorem: a^2 + b^2 = c^2
where a = height b = base and c = the largest side
Step 1. Find the length of AC (represented as a)
Answer: 9 units
Explanation: either count how many units or use the distance formula
Step 2. Find the length of CB (represented as b)
Answer: 4 units
Explanation: either count how many units or use the distance formula
Step 3. Substitute a for 9 and b for 4 units in Pythagorean Theorem
9^2 + 4^2 = c^2
Step 4. Simplify the exponents
81 + 16 = c^2
Step 5. Solve for c^2
c^2 = 81 + 16
c^2 = 97
Step 6. Square root c^2
c = √97

Sami orders cowboy hats online for a party. They cost $11.95 each with a shipping fee of $7.95.
Sami recently paid $223.05 for some cowboy hats.
Write an equation that to find the number of cowboy hats Sami ordered. Then find the number of
cowboy hats she ordered,
Answers
Answer:
223.05/x(11.95+7.95) 11.21.
Step-by-step explanation:
If each hat costs 11.95 plus a shipping fee of 7.95, you must add those numbers together. This makes the variable that will help indicate the number of hats ordered. Then you divide 223.05 by 19.9 (the total cost per hat) and you'll get your answer of 11.21 rounded.

A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.
He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.
Answers
Answer:
108π ft² or 339.29 ft²Step-by-step explanation:
Refer to attached picture.
The grazing area of the goat is 3/4 of area of circle with 12 ft radius:
A = 3/4(πr²) = 3/4(π*12²) = 108π or 339.29 ft²Tied to the corner
Means 1part among 4parts of circle or a quarter area

Which statement is true about the diagram?
A line has points A, K, B, T. The distance from A to B is 10, the distance from K to B is 5, and the distance from B to T is 4.
K is the midpoint of AB.
B is the midpoint of KT.
AK = BT
AB = KT
Answers
K is the midpoint of AB, which is the correct answer that would be option (A).
What is Midpoint?A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given shows a line segment AT, where the length of line segment AT refers to the distance between its endpoints, A and T.
Here AB = 10, KB = 5, and BT = 4.
Since AB = AK + KB,
We have that 10 = AK+5,
And AK= 10 - 5 = 5.
This means that AK = KB = 5 and K is the midpoint of AB
Therefore, K is the midpoint of AB, which is the correct answer that would be an option (A).

x = 70
Step-by-step explanation:
To find the value of x we need to
we know that the figure is an isosceles triangle so the base angles will be equal
we also know that angle sum of triangle is 180
so
40 + x + x = 180
40 + 2x = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70
