Does anybody know this?Find the area of the shaded region if PA=7 inches and PB=4 inches
Hi Student!
The first step that we must take before attempting to solve the problem is to gather important information. Looking at the problem we are given two lengths, PA and PB. These two lengths make up the radius of two different circles which we will need to find the area for both of them. The other important information that we must take in is that we are trying to determine the area of the shaded region.
Now that we have our important information concluded, let's move onto solving the problem. We know that we are trying to determine the area of the shaded region which means that we will need to do some subtraction between the total area of the larger circle and the total area of the smaller circle.
Area of a Circle Formula
[tex]A=\pi*r^2[/tex]Plug in the information
[tex]Shaded\ Region = Larger\ Circle - Smaller\ Circle[/tex][tex]Shaded\ Region = (\pi *PA^2)-(\pi*PB^2)[/tex][tex]Shaded\ Region = (\pi *(7\ in)^2)-(\pi*(4\ in)^2)[/tex]Simplify the exponents
[tex]Shaded\ Region = (\pi *49\ in^2)-(\pi*16\ in^2)[/tex]Subtract
[tex]Shaded\ Region = 49\ in^2*\pi-16\ in^2*\pi[/tex][tex]Shaded\ Region = 33\ in^2*\pi[/tex]Therefore, our final answer would be that the shaded region is 33 inches squared times pi which is best described in Option D. We got this after subtracting the area of the smaller circle from the area of the larger circle which provides us with the area of the shaded region.

can you please factorise 10fz-25z
Answer:
5z(2f - 5)
Step-by-step explanation:
What is the greatest common factor of 10 and -25? Both can be evenly divided by 5. Thus, divide both numbers by 5 and place the 5 outside of the parentheses.
(10fz - 25z) -----> 5(2fz - 5z)
Next, do the two terms share any variables? Both are multiplied by "z". Thus, you can divide each term by "z" and place it outside of the parentheses.
5(2fz - 5z) -----> 5z(2f - 5)
The terms no longer share any common factors. Therefore, your final answer is: 5z(2f - 5).

The triangle PSQ is an isosceles triangle, and the area of the triangle PSQ is 1360.62 square units
How to determine the area?The given parameters are:
PS = SQ
Perimeter, P = 50
SQ - PQ = 1
The perimeter is calculated using:
PS + SQ + PQ = 50
This gives
2SQ + PQ = 50
Make SQ the subject in SQ - PQ = 1
SQ = 1 + PQ
So, the equation 2SQ + PQ = 50 becomes
2(1 + PQ) + PQ = 50
Expand
2 + 2PQ + PQ = 50
Evaluate like terms
3PQ = 48
Divide by 3
PQ = 16
Substitute PQ = 16 in SQ - PQ = 1
SQ - 16 = 1
So:
SQ = 17
The area is then calculated using:
A = √[P * (P - PS) * (P - SQ) * (P - PQ)]
This gives
A = √[50 * (50 - 17) * (50 - 17) * (50 - 16)]
Evaluate
A = 1360.62
Hence, the area of the triangle PSQ is 1360.62 square units

Hi~!
Answer:
843
Step-by-step explanation:
We know that 58 is a even number, and so is 48,894. So we can check this by multiplying 843, which is th number I got when I divided it, and multiply that by 58, then we get 48,894.
I hope this helps!~ :)
Answer:
843
Step-by-step explanation:
In long division, first take the first digit of the dividend from the left. Check if this digit is greater than or equal to the divisor, then divide it by the divisor and write the answer on top as the quotient. After, subtract the result from the digit and write the difference below. Bring down the next digit of the dividend (if present). Lastly, repeat the same process.

4) Solve for x and find the measure of angle zxy
Answer:
Angle zxy = 55 degrees, x = 12
Step-by-step explanation:
Since the angle WXY is labeled as a right angle from the square in the angle, and angle WXZ is 35 degrees, we know that angle ZXY must be 55 degrees, because 55+35 = 90. Then to solve for x, we use the measure of angle ZXY to construct the equation 4x+7 = 55. subtract 7 from both sides to get 4x = 48, then divide both sides by 4 to arrive at the answer of x = 12.
