Answer:
38.4895
Step-by-step explanation:
area of circle = pi * r^2
3.142 * 7^2 = area of the whole circle
as we only have 1/4 of the circle we divide our area by 4
(3.142 *7^2) / 4 = 38.4895
Answer:
38.4895
Step-by-step explanation:
basically you are finding a quarter of the area of the circle. So the formula is 1/4πr^2
so that's 3.142×7^2 and then divided by 4.

The formula to find the area of a quarter of a circle: [tex]\frac{1}{4} * \pi * r^{2}[/tex], where [tex]r[/tex] is the radius (diameter ÷ 2) and the [tex]\pi[/tex] is alterable.
1) Substitute the given values into the formula.

hi people! so, i have a math dyslexia, this means i have a really hard time not only understanding math, but keeping up with all the problems and new stuff, could someone just give me an explanation of what algebra is in a way that you would describe it to a 5 year old?
Answer:
Math with letters
Step-by-step explanation:
Algebra is just like normal math but instead of you knowing all the numbers there are some numbers you dont know and those are replaced with letters. letters are there to you can replace them with any number, or if given the right problem you might have to find out what number replaces the letter to give you the right answer. for example take 1+x=2 here x would be replaced with 1 to make this true. or take y=2-x+3 if you replace x with any number you want that changes the (y) value to give you anything you want. Also the letters can be any letter you want they dont mean anything just there as place holders for numbers.

One angle of a parallelogram measures 20 what are the measures of the other three angles in the parallelogram
Answer:
160°, 20° and 160°[tex] \: [/tex]
Step-by-step explanation:
Let us assume A, B, C and D are the four angles of the parallelogram. Where, ∠A = 20° and we have to find the measure of ∠B, ∠C and ∠D
So, If ∠A = 20°, then So, also ∠C = 20°.
[Opposite angles of a parallelogram are equal to each other]Therefore,
The measure of ∠C is 20°⠀
And, ∠A and ∠B are adjacent angles. We know,
Sum of two adjacent angles = 180°So,
⇒ ∠A + ∠B = 180°
⇒ 20° + ∠B = 180°
⇒ ∠B = 180° – 20°
⇒ ∠B = 160°
So,
The measure of ∠B = 160°⠀
So, If ∠B = 160°, then So, also ∠D = 160°.
[Opposite angles of a parallelogram are equal to each other]Therefore,
The measure of ∠D is 160°Tiana lives 5/8 mile away from school. She walks halfway to school. How many

If an investor has a $5,000 pretax return, the state tax rate is 4.5%, and the federal tax rate is 22.0%, what is the real investment value? $1,325 $3,675 $3,900 $4,775
Based on the given parameters, the real value of the investment is $3675
How to determine the value of the investment?From the question, the given parameters about the investment are:
Pretax return = $5,000
State tax rate = 4.5%
Federal tax rate = 22.0%
The real value of the investment is calculated using the following formula
Real investment value = Pretax return - [(Pretax return * State tax rate) * Pretax return * Federal tax rate)]
Substitute the given values in the above equation.
Real investment value = 5000 - [(5000 * 4.5%) + (5000 * 22.0%)]
Evaluate the products
Real investment value = 5000 - [225 + 1100]
Evaluate the sum in the above equation
Real investment value = 5000 - 1325
Evaluate the difference in the above equation
Real investment value = 3675
Hence, the real value of the investment is $3675

The image shows a circle with center (4,6) and radius 10 units.
Answer:
A, B, D, E
Step-by-step explanation:
Every point is on the circle except for the middle one
The points lying on the circle will be (-4, 12), (-6, 6), and (4, 16). Then the correct options are A, B, and E.
What is the equation of a circle?Let r be the radius of the circle and the location of the center of the circle be (h, k). Then the equation of the circle is given as,
(x - h)² + (y - k)² = r²
The center is at (4, 6) and the radius is 10 units. Then the equation of the circle is calculated as,
(x - 4)² + (y - 6)² = 10²
(x - 4)² + (y - 6)² = 100 .......1
Substitute (-4, 12) in equation 1, then we have
(-4 - 4)² + (12 - 6)² = 100
100 = 100
Substitute (-6, 6) in equation 1, then we have
(-6 - 4)² + (6 - 6)² = 100
100 = 100
Substitute (13, 10) in equation 1, then we have
(13 - 4)² + (10 - 6)² = 100
97 ≠ 100
Substitute (-4, 12) in equation 1, then we have
(4 - 4)² + (16 - 6)² = 100
100 = 100
If the equation is satisfied, then the point lies on the circle.

A simple random sample is drawn from a normally distributed population, and when making a statistical inference about the population mean, the margin of error is found to be 5.9 at a 95% level of confidence. if the mean of the sample is 18.7, what is the 95% confidence interval for the population mean? 18.7 ± 5.9 18.7 ± 9.7 18.7 ± 11.6 18.7 ± 15.2
If the mean of the sample is 18.7, The 95% confidence interval for the population mean is 18.7 ± 11.6.
Confidence intervalz-score for 95% confidence interval =1.96
Lower limit of the interval:
Lower limit=Sample mean-(Z-score×Margin of error)
Lower limit=18.7-(1.96×5.9)
Lower limit=18.7-11.564
Lower limit=18.7-11.6 (Approximately)
Upper limit of the interval:
Upper limit=Sample mean+(Z-score×Margin of error)
Upper limit=18.7+(1.96×5.9)
Upper limit=18.7+11.564
Upperr limit=18.7+11.6 (Approximately)
Hence:
Confidence interval= 18.7 ± 11.6
Therefore the 95% confidence interval for the population mean is 18.7 ± 11.6.

What two integers does sqrt41 fall between? explain reasoning
Answer:
Below!
Step-by-step explanation:
Given square root:
[tex]\sqrt41[/tex]
Let's note a few perfect square roots.
[tex]1 = \sqrt{1 \times 1} = \sqrt{1}[/tex]
[tex]2 = \sqrt{2 \times 2} = \sqrt{4}[/tex]
[tex]3 = \sqrt{3 \times 3} =\sqrt{9}[/tex]
[tex]4 = \sqrt{4 \times 4} =\sqrt{16}[/tex]
[tex]5 = \sqrt{5 \times 5} =\sqrt{25}[/tex]
[tex]6 = \sqrt{6 \times 6} =\sqrt{36}[/tex]
[tex]7 = \sqrt{7 \times 7} =\sqrt{49}[/tex]
[tex]8 = \sqrt{8 \times 8} =\sqrt{64}[/tex]
And so on...
When looking at the perfect square roots we identified, we can say that:
[tex]\sqrt{36} < \sqrt{41} < \sqrt{49}[/tex]
Therefore,
[tex]6 < \sqrt{41} < 7[/tex]
We can conclude that [tex]\sqrt{41}[/tex] is between 6 and 7.
