Find the value of each variable.
y =
z =
Answer:
z=70 degrees y=117 degrees
Step-by-step explanation:
To find angle z, you have to know that when two sides are against each other, they have to equal 180 degrees so 180-110 is equal to 70. Therefore z is equal to 70 degrees. To find y, you have to know that a quadrilateral's total degrees is equal to 360 degrees. Therefore, you have to do 360-93-80-70 which is equal to 117 degrees. Therefore y is equal to 117 degrees.

Answer each question. Show your reasoning. a. 125% of e is 30. What is e? b. 35% of f is 14. What is f?
Answer: a. e= 24
b. f = 40
Step-by-step explanation:
a. 125% of e = 30
125/100 × e = 30
1.25 × e = 30
1.25e = 30
e = 30/1.25
e = 24
b. 35% of f = 14
35/100 × f = 14
0.35 × f = 14
0.35f = 14
f = 14/0.35
f = 40

Area of a circle = pi x r^2
R is the radius which is half the diameter.
You are given the diameter so divide that by 2 to get the radius:
36/2 = 18
Now using the formula above:
Area = pi x 18^2
Area = 1017.4
The answer is A. 1017.4
Area = 1017.4
The answer is A. 1017.4

1) The equation below shows the height of a soccer ball, h(d) meter as a function of the
horizontal distance, d meters the ball travels until it hits the ground. The ball is kicked when
it is on the ground. h(d) = -0.025(d – 20)2 + 12
Always make a sketch to begin even if you are not asked to!
a) What is the maximum height of the ball?
b). What is the horizontal distance of the ball from the kicker when it reaches its maximum
height?
c) How far does the ball travel horizontally from when it is kicked until it hits the ground?
For the given equation
a)The maximum height of the ball is 12 meters.
b)The horizontal distance of the ball from the kicker is 20 meters.
c)The ball travels approximately 32.85 meters horizontally.
What does equation mean?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Solving an equation means finding the value(s) of the variable(s) that make the equation true.
According to the given informationa) The equation is in vertex form, where the maximum height is the y-coordinate of the vertex. We can see that the vertex is at (20, 12), so the maximum height of the ball is 12 meters.
b) The horizontal distance of the ball from the kicker when it reaches its maximum height is the x-coordinate of the vertex. In this case, the vertex is at (20, 12), so the horizontal distance of the ball from the kicker when it reaches its maximum height is 20 meters.
c) To find the distance the ball travels horizontally from when it is kicked until it hits the ground, we need to find the value of d when h(d) = 0. This is because the ball hits the ground when its height is 0. Setting h(d) = 0, we get:
0 = -0.025(d – 20)2 + 12
Solving for d, we get:
(d – 20)2 = 480
d – 20 = ±√480
d = 20 ± 4√30
Since the ball is kicked when it is on the ground, we only consider the positive value of d:
d = 20 + 4√30
Therefore, the ball travels approximately 32.85 meters horizontally from when it is kicked until it hits the ground.

A company is deciding which box to us for their merchandise. The first box measures 8in by 6.25in by 10.5in. The second box measures 9in by 5.5in by 11.75in. Which box required more material to make?
Answer:
the second box
Step-by-step explanation:
To determine which box would use more material to make, the volume of the boxes have to be determined. the box with the larger volume would require more material to make
Volume of a box = length x breadth x height
Volume of box 1 = 8in x 6.25in x 10.5in = 525 in³
Volume of box 2 = 9in x 5.5in x 11.75in = 581.6 in³
the second box has a larger volume and thus would need more material to make

Write an equation for the nth term of the geometric sequence 6. - 54, 486,
Given:
The geometric sequence is:
[tex]6,-54,486,...[/tex]
To find:
The equation for the nth term of the given geometric sequence.
Solution:
We have the given geometric sequence,
[tex]6,-54,486,...[/tex]
Here, the first term is 6 and the common ratio is:
[tex]r=\dfrac{-54}{6}[/tex]
[tex]r=-9[/tex]
The nth term of a geometric sequence is:
[tex]a_n=ar^{n-1}[/tex]
Where, a is first term and r is the common ratio.
Putting [tex]a=6,r=-9[/tex] in the above formula, we get
[tex]a_n=6(-9)^{n-1}[/tex]
Therefore, the equation for the nth term of the given geometric sequence is [tex]a_n=6(-9)^{n-1}[/tex].
