All of the quadrilaterals in the shape below are squares. Find the area of the shaded
region.
4
6
The area of shaded region is 32 square units.
What is area ?"The area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure. The area is measured in square units such as square centimeters, square feet, square inches, etc."
To find the area of the shaded region
1. Find the area of the biggest square ([tex]A_{1}[/tex])
Formula for area of a square
[tex]A_{1}[/tex] = side × side
⇒[tex]A_{1}[/tex] = 10×10
⇒[tex]A_{1}[/tex] = 100 square units.
2. Find the area of the unshaded region ([tex]A_{2}[/tex])
[tex]A_{2}[/tex] = X(biggest square)+ 2.Y(smallest square)
⇒[tex]A_{2}[/tex] = [tex](6[/tex]×[tex]6)[/tex] + [tex]2(4[/tex]×[tex]4)[/tex]
⇒[tex]A_{2} =36+2.(16)[/tex]
⇒[tex]A_{2}=68[/tex] square units
3. Find the difference of [tex]A_{1}[/tex] and [tex]A_{2}[/tex]
Area of the shaded part = [tex]A_{1}[/tex] - [tex]A_{2}[/tex]
= 100-68
= 32 square units.
Hence, The area of shaded region is 32 square units.

Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. You must use the fact that opposite angles in a quadrilateral are supplementary.
Show me:
(a) supplementary equation used to solve for x (1 point)
(b) all math used to calculate for x (1 point)
(c) correct value for x (1 point)
(d) plugging x into expressions for angles A, C, D (1 point)
(e) show all math used to calculate the measures of angles A, C, D (2 points)
(f) all math used to calculate the measure of angle B (1 point)
Answer:
see image
Step-by-step explanation:
Supplementary means the angles add up to 180°.
Add the given angles and set equal to 180°
To solve, combine like terms, add 10, divide by two to get x all by itself.
Replace x with 95 to find the measures of Angles A, C, D.
Use the supplementary definition a second time to find the measure of Angle B.

Hello.
The correct word is "multiplied by"
Eight multiplied by a number n equals 8n.
Remember that
[tex]\bigstar[/tex] We always write the number next to the variable.
[tex]\bigstar[/tex] We write the number and the variable together.
Can we write 8×n? Sure! However, we usually write it as
8n

Answer:
girls = 61
boys = 73
Step-by-step explanation:
Let x = number of girls
Let y = number of boys
Given the difference between the number of the girls and the number of the boys in the outdoors club is 12:
⇒ y - x = 12
Given there are 4 times the number of the girls decreased by 25 equals 3 times the number of the boys:
⇒ 4x - 25 = 3y
Rearrange x - y = 12 to make y the subject:
⇒ y = 12 + x
Substitute x = 12 + y into 4x - 25 = 3y and solve for y:
⇒ 4x- 25 = 3(12 + x)
⇒ 4x- 25 = 36 + 3x
⇒ x = 61
Now we have found the value of x, substitute this into y = 12 + x and solve for y:
⇒ y = 12 + 61
⇒ y = 73
On a trip Joel drove 25 miles more than half the number of miles
Rita drove. Together they drove 340 miles. How many miles did
Joel drive?
Answer:
194
Step-by-step explanation:
you would do 340 divided by 2 and that gets you 170 then you would subtract 24 from Rita and that is 146 so Rita drove 146 miles. then for Joel you add 170 +24 = 194. So Joel drove 194 miles.

Toby thinks of a number less than 15. He divides it by 2 and then he adds 4. He then divides it by 3. His answer is 3.5
Answer:
13
Step-by-step explanation:
For this problem, work backwards to determine what the starting number was. Take 3.5 and multiply it by 3 to get 10.5, then subtract 4 to get 6.5. Finally, multiply 6.5 by 2 to get the starting number, which is 13. To check your work, you can always take 13 and perform the operations to make sure you end up with 3.5.

Select the correct answer. The perimeter of a triangle is 30 units. If it’s is dilated with respect to origin by a scale factor of 0.5, what is the perimeter of the resulting triangle?
Answer: 15
Step-by-step explanation:
We know that the scale factor of the dilation is the ratio of similtude, and that the ratio of similitude is equal to the ratio of the perimeters. So, the new perimeter is 30(0.5)=15.

Kelly invested $5,000 in a cd at charter bank. the annual rate is 4.9% compounded monthly. how much is her investment at the end of 8 years? round to the nearest hundredth.
The investment of the kelly at the end of 8 years is $7393.78.
What will be the investment of kelly at the end of 8 years?It is given that

Given a polynomial function f(x) = 2x2 – 3x + 5 and an exponential function g(x) = 2% – 5, what key features do f(x) and g(x) have in common?

Domain[tex]Dom \{f(x)\} = \mathbb{R}[/tex]
[tex]Dom \{g(x)\} = \mathbb{R}[/tex]
Both functions are continuous.
Range[tex]Ran \left\{f(x)\right\} = (3.875, +\infty)[/tex]
[tex]Ran \{g(x)\} = (-5, +\infty)[/tex]
x-Intercepts[tex]f(x):[/tex] [tex](x,y) = \emptyset[/tex]

[tex]g(x) :[/tex] According to the graph, [tex]g(x)[/tex] increase over the interval of [tex]\mathbb{R}[/tex]

Factor the following polynomials by finding a GCF.
Answer:
5mn(2m + 6n + 1)
Step-by-step explanation:
Look at the coefficients (the numbers): 10, 30, 5
The greatest common factor of 10, 30, and 5 is 5.
Now look at the variable parts of the three terms.
Start with the variable m.
There is m², m, and m.
The GCF of m², m, and m is m.
Now look at the variable n.
There is n, n², n.
The GCF on n, n², and n is n.
The GCF for the entire polynomial is 5mn.
Now we factor out 5mn from all terms.
To factor out 5mn, you divide each term by the GCF, 5mn.
10m²n + 30mn² + 5mn = 5mn(2m + 6n + 1)
