Find the area of the circle.
Answer:
50.24 centimeters squared
Step-by-step explanation:
The diameter (d) is 8 which means the radius is 4 (8/2)
we use the formula pi x radius^2
It says to use 3.14 for pi
so the equation is 3.14(4)^2=3.14 x 16 = 50.24
Answer:
50.24 centimeters squared

3) A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then
find AB
Answer:
AB = 8
Step-by-step explanation:
A is between B and C. If BC= 8x + 5, AB= 2x + 4, and AC= 3x + 7, then find AB
Step 1
Find x
BC = AB + AC
8x + 5 = 2x + 4 + 3x + 7
Collect like terms
8x - 2x - 3x = +4 + 7 - 5
3x = 6
x = 2
Step 2
Find AB
= AB= 2x + 4
AB = 2(2) + 4
AB = 4 + 4
AB = 8

What is the value of tan c
Answer:
In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735.
A bookcase has 5 of these bookshelves that are 42 inches long. How many FEET of shelf space is there? Explain your reasoning.
Answer:

zach says that the expressions 6x - 36 and 3(2x -12) are equivalent
Answer:
True
Step-by-step explanation:
When you distribute the 3, you get x(2x3)-(12x3)
2x3=6
12x3=36
so 6x-36
and that is equivalent to the first expression.

If sally has 90000000 apples and gives her freind sophie 1900 of them , and keeps 900 apples for her self hown many apples did she give to charity?1
Answer: 89,998,910
Step-by-step explanation: if she gives 1900 away and keeps 900 then I’m assuming she gives the rest away to charity and that would be 89,998,910 apples
Answer:
She gave 89997200 apples to charity
Step-by-step explanation:
90000000 - 1900 - 900 = 89997200
or
90000000 - (1900 + 900) = 89997200
A parallelogram has a base of 9 units and a corresponding height of į units. What is its area?
Do not include units (square units) in your answer.
Answer:
[tex]Area = 9j[/tex]
Step-by-step explanation:
Given
[tex]Base = 9\ units[/tex]
[tex]Height = j\ units[/tex]
Required
Determine the area
Area of parallelogram is calculated as thus:
[tex]Area = base * Height[/tex]
Substitute values for Base and Height
[tex]Area = 9 * j[/tex]
[tex]Area = 9j[/tex]
Hence, the area of the parallelogram whose base is 9 units and height is j units, is 9j

Find the value of z such that 0.02 of the area lies to the right of z. Round your answer to two decimal places.
The value of z-score such that 0.02 of the area lies to the right of z would be 2.06.
Given that,
0.02 of the area lies to the right of z.
Now, for the value of z such that 0.02 lies to the right of z, we can make use of the standard normal distribution table.
Since to determine the value of z such that 0.02 of the area lies to the right, we need to find the z-score associated with the cumulative probability of (1 - 0.02) = 0.98
Now for the value of 0.98 in the standard normal distribution table, we find that the corresponding z-score is 2.06.
Therefore, the value of z, rounded to two decimal places, is 2.06.

The value of z such that 0.02 of the area lies to the right of z is approximately 2.05 (rounded to two decimal places).
To find the value of z such that 0.02 of the area lies to the right of z, we need to determine the z-score associated with that probability.
Since we're looking for the area to the right of z, we can use the standard normal distribution table or a statistical calculator to find the corresponding z-score.
By searching the table or using a calculator, we can find that the z-score associated with a right-tail probability of 0.02 is approximately 2.05.

Find the distance between (6,4) and (-6,-5) by using the distance formula
Answer:
[tex]\boxed {d = 15}[/tex]
Step-by-step explanation:
Use the Distance Formula to help determine the distance between two given points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
First point: [tex](x_{1}, y_{1})[/tex]
Second point: [tex](x_{2}, y_{2})[/tex]
-Substitute both given points:
[tex](x_{1}, y_{1}) = (6, 4)[/tex]
[tex](x_{2}, y_{2}) = (-6, -5)[/tex]
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-6 - 6)^{2} + (-5 - 4)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + (-9)^{2}}[/tex]
[tex]d = \sqrt{144 + 81}[/tex]
[tex]d = \sqrt{225}[/tex]
[tex]\boxed {d = 15}[/tex]
Therefore, the distance is [tex]15[/tex].
Consider the equation 5x + 7 = 2x + 28. Your tasks to explain the steps you would take, in
order, to solve the equation for x. Imagine that you are writing this for someone who is learning
about this process for the first time. You would be as specific as possible and write in complete
sentences.
Answer:
x=7
Step-by-step explanation:
Step 1: Put the variables and constants on the same side and change their signs so it'll look like this 5x-2x = 28 - 7, you always move the smaller number to either the left or right depending on its position in the problem.
Step 2: solve each side normally like this, 3x = 21
Step 3: to get x by itself divide 3 on both sides and you should get x=7
Here's a run through of the steps
5x+7=2x+28
-7 -7(subtract 7 from both sides
5x=2x+28-7
-2x -2x(subtract 2x from both sides)
5x-2x=28-7
3x=21
3x/3 = 21/3 (divide 3 from both sides)
x=7

A swimming pool has two pipes coming into it to fill it with water. One pipe takes 16 hours to fill it. The other takes 12 hours to fill it. How many hours will it take both pipes to fill the pool?
Answer:
8 hours
Step-by-step explanation:
8 hours because half of 16 is 8 and half of 12 is 6
If it takes 6 hours to fill one half then the other 2 hours would go to the other pipe making it 8 hours
