Find the are of the shaded region
Answer:
[tex] 379.69 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of the shaded region = Area of the square with side 25 ft - Area of the semicircle with radius (25/2) = 12.5 ft.
[tex] = {(25)}^{2} - \frac{1}{2} \times \pi \times {(12.5)}^{2} \\ \\ = 625 - \frac{1}{2} \times 3.14 \times 156.25 \\ \\ = 625 - 245.3125 \\ \\ = 379.6875 \: {ft}^{2} \\ \\ = 379.69 \: {ft}^{2} [/tex]

Use complete sentences to describe the steps involved in solving x2 − 64 = 0 two different ways.
Answer:
1. First, add 64 to bith sides, cancelling one out and taking it to the other side, then dividing by two, giving you x=32.
2. Subtract 2x and take it to the other sude of the equation. Then divide -2 by -64, giving you x=32, due to the negative cancelling (turning to a positive).

Find the measure of ZAOE in the diagram below.
90
100
120
130
========================================================
Explanation:
The three upper angles
AOBBOCCODall combine together to form a 180 degree straight angle. Let's add up the angle expressions and set the result equal to 180. That will help us solve for x.
(angle AOB) + (angle BOC) + (angle COD) = 180
(3x-28) + (90) + (66-x) = 180
2x+128 = 180
2x = 180-128 .... subtract 128 from both sides
2x = 52
x = 52/2 .... dividing both sides by 2
x = 26
Since x = 26, we can find the missing angles like so
angle AOB = 3x-28 = 3*26-28 = 50angle COD = 66-x = 66-26 = 40Note how:
(angle AOB) + (angle BOC) + (angle COD) = 50+90+40 = 180
to help confirm we have the correct x value.
--------------------------------------
Afterward, we need to find angle BOD which is the combination of angles BOC and COD
angle BOD = (angle BOC) + (angle COD)
angle BOD = 90 + 40
angle BOD = 130
Angles BOD and AOE are vertical angles. It might help to erase ray OC so you can see the two vertical angles better. Vertical angles are always congruent, which means angle AOE is 130 degrees as well.

Andrea was asked to find the value of –32 × 9 × 5/4 . How can Andrea make this problem easier to compute?
Answer:
divide the 32 by 4:
then the equation becomes:
8 x 9 x 5 = 360
this is the same as 32 x 9 x 5/4 = 360
The value of given expression is -360.
What is Equation?An equation is a statement that proves that two expressions connected by the equals sign "=" are equal.
In algebra, an equation is a condition on a variable. It only applies to a specific variable value.
Algebra takes into account two prominent families of equations: linear equations and polynomial equations.
Given -32 x 9 x 5/4
since equation is in multiple form
32 is divided by 4 completely
32/4 = 8
and equation become
-8 x 9 x 5
follow the multiplication we get
-360.
Hence the product is -360.

In class A, 15 out of the 30 students are girls, and in class B, 24 out of the 40 students are girls. Which class has a higher percentage of girls?
Answer:
Class B
Step-by-step explanation: 15 out of 30 is 50% and 24 out of 40 is 60% because 24 out of 40 is also the same as 12 out of 20. 20*5 = 100, so 12*5= 60. 60>50

1. A limited-edition soccer ball costs $30, and the
sales tax is 6%. What is the total cost?
Answer:
$31.80
Step-by-step explanation:
The ball will cost 100% of its price plus 6% of its price for a total of 106%.
To use percentages as a factor and multiply, they must be divide by 100, making the multiplication factor version of 106% 1.06.
Multiply the cost of the ball by your multiplication factor:
30 x 1.06 = 31.8
Money is written to two decimal places, making your answer $31.80
Answer:
$31.80
Step-by-step explanation:
First, find how much the sales tax is
$30 × 6%
Convert the percentage into a decimal
30 × 0.06
1.8
$1.80
Add the sales tax to the original cost
$30 + $1.80
$31.80

It is C.
Step-by-step explanation:
So,A triangle is equal to 180 and you would add up the numbers you already have which equal 145.180-145= 35° and thats why the last letter would be 35° in your answer and be correct which would be that m<F=35° is the same as ABC in the last letter. Since,<B is the second letter in ABC and so is <E in DEF and have the same degree that would be the same as well so I hope that helps:)
Answer:
c
Step-by-step explanation:
the angles in a triangle have to add up to 180°
65 + 80 = 145
180-145 = 35
the missing angle is 35°
choice c matches because it has 2 of the same angle measures, which means they all have to be the same

Paul wants to place an ad in a newspaper. The newspaper charges $10 for the first 2 lines of
text and $3 for each additional line of text. Paul's ad is 8 lines long. How much will the ad cost
Answer:
$38
Step-by-step explanation:
$10 × 2= $20
Therefore the first two lines cost $20
$3 for each additional line of text
since the total lines are 8 lines therefore 8 -2=6
$3 × 6=$18
Tolat cost: First two lines + additional lines
$20+$18= $38

Michael has a jar of dimes and nickels there are 152 dimes and nickels in the jar that total $11
Answer:
Michael has 84 nickels and 68 dimes in a jar.
Step-by-step explanation:
Let n = number of nickels
Let d = number of dimes
n + d = 152
5n + 10d = 1100
(5n + 10d = 1100)/5
n + 2d = 220
- n + d = 152
d = 68
n + 68 = 152
- 68 - 68
n = 84
Michael has 84 nickels and 68 dimes in a jar.
What is the sum of a square
Answer:
The sum of squares is the sum of the squares of variation, where variation is defined as the separate between individual value and the mean. to determine the sum of squares, the distance between each data point and the line of best fit is a squared and then summed up. the line of best fit will minimise dis value.
