Answer:
[tex]A=24[/tex]
Step-by-step explanation:
For finding the area of a trapezoid you first have to use the correct formula which is [tex]A=\frac{1}{2}(b_1+b_2)h[/tex].
Now we plug in what we already know.
[tex]A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)[/tex]
Now we start with the parenthesis
[tex]A=\frac{1}{2}(12)(4)[/tex]
Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally
[tex]A=24[/tex]

A container is in a shape of a right circular cylinder standing on its base. If 100 cubic centimeters of water is poured into the container the height of the water is 8 centimeters. What is the height of the water if only 75 cubic centimeters is poured into the container?
A) 2.1 cm
B) 3.8 cm
C) 6.0 cm
D) 6.9 cm
E) 10.7 cm
And why???
Answer:
Step-by-step explanation:
The shape of the container isn’t changing here, so the height of the water will be proportional to the volume. 75 cm^3 is ¾ of 100 cm^3, so the water will rise ¾ as high.
¾ of 8 cm is 6 cm.

The pair of equations that can be used to find x and y are:
x + y = 62
(1.02)x = 7
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Here, we have,
The form of the pair of equations would be:
hours worked last week + hours worked this week = total hours worked both weeks equation 1
(1 + percent increase/100) x hours worked last week = hours worked this week equation 2
x + y = 62 equation 1
(1 + 20/100) ×x = y
(1.02)x = 7 equation 2
The two equations can be solved using either of these three methods:
elimination method
substitution method
graph method

What is probability?Probability is a branch of mathematics that deals with the study of random events or outcomes.
It is concerned with determining the likelihood of an event or outcome occurring in a given situation.
The probability of an event is a number between 0 and 1, with 0 indicating that the event is impossible and 1 indicating that the event is certain.
The average of dice roll is:
Average = 1/100 (15 x 1 + 18 x 2 + 14 x 3 + 16 x 4 + 19 x 5 +18 x 6)
Average = 1/100 (15 + 36 + 42 + 64 + 95 + 108)
Average = 1/100 x 36
Average = 3.6
Thus, the answer is 3.6.

The area of a composite shape is the sum of the areas of its individual shapes
The area of the composite shape is 215.20 square feet.
From the figures, we have the following shapes
A semicircle with a diameter of 22 ftA semicircle with a diameter of 8 ft (i.e. 30ft - 22ft)The area (A) of a semicircle is:
[tex]\mathbf{A = \frac{\pi d^2}{8}}[/tex]
So, the area of the composite shape is:
[tex]\mathbf{A = \frac{\pi (d_1^2 + d_2^2)}{8}}[/tex]
This gives
[tex]\mathbf{A = \frac{\pi (22^2 + 8^2)}{8}}[/tex]
[tex]\mathbf{A = \frac{\pi (548)}{8}}[/tex]
[tex]\mathbf{A = 68.5\pi}[/tex]
[tex]\mathbf{A = 215.20}[/tex]
Hence, the area of the composite shape is 215.20 square feet.

Estimate the perimeter and the area of the shaded figure
Show how you got your answer
Answer:
Perimeter = 16 feet
Total Surface Area = 24 sq ft.
Step-by-step explanation:
Let's assume that each square is equal to 1 foot. Using this we can estimate the perimeter and area as the following. For perimeter, we simply add all the squares distances surrounding the shaded object.
Perimeter = 16 feet (4 feet for the top and bottom and 2 feet every diagonal)
For the area, we need to calculate the area of the square in the middle and then the area of the two triangles.
Square = L * W
Square = 4 * 4
Square = 16 sq ft
Triangle = 0.5 * Base * Height
Triangle = 0.5 * 4 * 2
Triangle = 4 sq ft
Both triangles = 4 sq ft * 2 = 8 sq ft.
Now we add both area totals:
Total Surface Area = 16 + 8
Total Surface Area = 24 sq ft.

Answer:
X=8
z=80
Step-by-step explanation:
Okay to find X you gotta find the other angle.
The other angle is 100 which is also vertical To (6x+52)
Vertical angles are equal or congruent so you cna make an eqaution to equal it
6x+52=100
Solve it like a normal equation
x=8
To find Z you gotta realize that 4 angles equal 360 degrees.
We knwo the two vertical angles, 100 and 100. Z is vertical to no name angle so its equal so it can also be Z. Z+Z=2z
Now If you add em all up you should get 360
2z+100+100=360
2z+200=360
Solve from here
z=80
