In the square below, the two semi-circles are congruent. Find the area of the
shaded region. If necessary, round your answer to two decimal places.
Answer:
3.44.
Step-by-step explanation:
We can see that in this square, the radii of the semicircles are 2. Using that, we can calculate that the area of each one is 6.58. Both combined is 12.56. Now, the original area of the circle was 16. 16 minus 12.56 is equal to 3.44, so the area of the shaded region is 3.44.

Analysis:
2(5x+4)=17
Distribute10x+8=17,
Subtract 8 from both sides to isolate x10x=9
Divide both sides by 10 to isolate xx=9/10 (ans)
Answer:
x = 9/10
Step-by-step explanation:
2(5x + 4) = 17
Distribute
10x+8 =17
Subtract 8 from each side
10x +8-8 = 17-8
10x = 9
Divide by 10
10x/10 = 9/10
x = 9/10

Answer:
Oki Doki, read below this will be long.
Step-by-step explanation:
So, lets start with mr moy.
First off, we need to figure out the total hours that mr moy worked.
Throuhgout the 7 days of the week, he worked 5 days. These were his hours:
8, 8, 8, 8, 9
Adding these together, you get a total of 41 hours.
Next we have total wage.
To find this, multiply the total hours by the hourly income. We know the hourly income is 12.5, and the total hours is 41:
12.5*41=512.5
So 512.5 is the total wage.
Lets do this for the next four people, I am just going to speed it up a bit:
Ms wong - hours - 8+8+7+9+9 =41. Hourly income - 9.5. Total income: 9.5*41:
389.5 is total income
41 is total hours
Maria - hours - 5+5+6+8+9=33. Hourly income - 7.5. Total income: 7.5*33:
247.5 total income
33 total hours
Tom - 4+4+4+4+4+8+8=36. Hourly income - 7.5. Total income: 7.5*36:
270 total income
36 total hours
Jacob - 5+5+5+7+7 =29. Hourly income - 7.5. Total income: 7.5*29:
217.5 total income
29 total hours
OK, now for the total sums:
Total hourly wages - 7.5+7.5+7.5+12.5+9.5=44.5
Total of the total hours - 41+41+33+36+29=180 hours
Total of total wages - 217.5+512.5+389.5+270+247.5=1637
Ok, thats it for the first page.
On the next pages, I was slightly confused. But Ill try my best.
A - for each employ, calculate total hours and wages. We already did this before.
B - What is the total amount that is paid out in wages in a week. We already did this before(1637)
C - which day is the busiest day of the week - Saturday. The slowest? Monday
So we know the slowest day has to be monday, since the total employment hours is 8+8+4=20. WHich is lower than the rest.
We also know the busiest day has to be saturday, since the total employment hours is 9+9+8+5=31. Which is higher than the rest.
Now to the the third page.
What is the average employe wage?
Lets add up all the wages, and divide by the amount of wages:
7.5+7.5+7.5+9.5+12.5=44.5
44.5/5
=
8.9
This is the average wage.

A class' test scores are normally distributed with a mean of 48 points and a standard
deviation of 3 points. What percentage of test scores are are between 47 and 52
points? Round to the nearest hundredth of a percent.
Answer:
53.94%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 48 points
σ is the population standard deviation = 3 points
For x = 47 points
z = 47 - 48/3
= -0.33333
Probability value from Z-Table:
P(x = 47) = 0.36944
For x = 52 points
z = 52 - 48/3
= 1.33333
Probability value from Z-Table:
P(x = 52) = 0.90879
Hence, the probability of test scores that between 47 and 52 points is calculated as:
P(x = 52) - P(x = 47)
= 0.90879 - 0.36944
= 0.53935
Therefore, the percentage of test scores that are between 47 and 52
points is given as:
0.53935 × 100
= 53.935%
Approximately to the nearest hundredth of a percent ≈ 53.94%

Use the equation to predict the number of visits per week to a coffee shop that is 3 blocks away.
Answer:
y = (-1 visit/block)x + 9 visits
6 visits
Step-by-step explanation:
The y-intercept is 9 (meaning 9 visits per week).
Note that (1, 8) is a point on the line.
To find the equation of this line, start with the slope-intercept form y = mx + b. We know that when x = 1, y = 8 and that the y-intercept, b, is 9. Therefore:
8 = m(1) + 9.
Solve this by subtracting 9 from both sides. We get:
-1 = m
The slope is m = -1 visits/block
and the desired equation is y = (-1 visit/block)x + 9 visits
If a particular coffee shop is 3 blocks away, we predict that the number of visits per week made to this shop is y = -1(3) + 9, or 6 visits

Which set of ordered pairs does not represent a function? O {(4, -6), (-5,5),(-6,0), (7,0)} O {(0, -4), (9,6), (2,8), (8,8)} O {(8,-6), (9,-8), (2,4), (3, -6)} o {(-5,2), (3,-9),(-1,8), (-5,9)}
Function is a set of ordered pairs that do not have same domain or x-value. That means in a set of ordered pairs, the domain cannot have same value.
The only relation that isn't function here is the last choice because in a set of ordered pairs, there are two -5's which is repetitive. Other choices do not have same x-values in one set except for the last choice.

Answer:
b ≥ 4
Step-by-step explanation:
12b + 12 ≥ 60
Subtract 12 from each side

12b ≥ 48
Divide each side by 12
12b/ 12 ≥ 48/12

12b ≥ 48
2) divide both members by 12
12/12 b ≥ 48/12
b ≥ 4
for graph the solutions we have to draw two lines
the first one is an horizontal line that has as equation the right part of the inequality
y = 60
the second one is a line the that passes from the origin and interecpts the first line in (4;60). 4 is the the first number that can be a possible value of the inequality
Equation a line that passes for two points A (0,0) , B (4,60)
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y - 60)/ (0 -60) = (x - 4) / (0-4)
(-y+60)/60 (-x+4)/4
-y + 60 = -15x + 60
y = 15x
the solutions of the inequality are all the points between the two lines with x≥4 and y≥60
A soccer field is 110 yards long and 80 yards wide. What is the longest pass that one player can make to another player on a soccer field?
Answer and Step-by-step explanation:
To find the answer, we need to first think of what length in the rectangle can make the longest path, then use the Pythagorean Theorem.
The diagonal in a rectangle (going from one corner to another) is the longest distance.
If we were to split that rectangle by its diagonal, we would get a triangle. By the Pythagorean Theorem, we can find the length of that diagonal (the hypotenuse of the triangle).
[tex]A^2 + B^2 = C^2\\\\110^2+80^2 = C^2\\\\12100 + 6400 = C^2\\\\18500 = C^2\\\\10\sqrt{185} = C = 136.0147 yards[/tex] <- This is the answer (the decimal version or this ^ version).

Twenty-two percent of the large pieces of mail that Rachel received this week were magazines and the rest were catalogs. Of the catalogs, 36 percent were for clothing.
To the nearest whole percent, what is the probability that a randomly chosen large piece of Rachel’s mail was a clothing catalog?
Answer:
28%
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Percent of catalogues received = 100% - percent of magazines received
100 - 22 = 78%
Percent of clothing catalogues = 0.78 x 36 = 28%

**If necessary, round to the nearest tenth**
98 units
34 units
9.9 units
5.8 units
Answer:
d = 9.9 units
Step-by-step explanation:
Picture a right triangle with one acute vertex at (1, -5) and the other at (-6, 2). Going from one to the other, we see a change in x (run) of 7 and a change in y of 7. Applying the Pythagorean Theorem, we find the distance between the two points as follows:
d = √(7² + 7²) = 7√2, or approximately 9.9 units.

15 ft
21 ft
23 ft
Answer:
b on edge 2021
Step-by-step explanation:
From the calculations, the length of CY in the parallelogram is 15 feet.
What is a diagonal?A diagonal is a line that runs from one end to another in a quadrilateral. We know that in such quadrilaterals as the parallelogram, the diagonals bisect each other.
Hence;
CY =WC
And
2x - 7 = x + 4
collecting like terms;
2x - x = 4 + 7
x = 11
Thus
CY = 2x - 7
= 2*11 - 7
= 22- 7
= 15

a.0.90

d. 0
The value of P(A and B) = 0.08
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that, A and B are independent events. P(A)=0.80 and P(B)=0.1
Since the events are independent
so, the formula used to find P(A and B) is
P(A and B) = P(A) x P(B)
P(A)= 0.80
P(B) = 0.10
Finding P(A and B)
P(A and B) = P(A) * P(B)
P(A and B) =0.80 x 0.10
P(A and B) = 0.08
