Answer:
Dilate Circle A by a scale factor of 3
Step-by-step explanation:
Circle A has a radius of 3, Circle B has a radius of 9. By dilating Circle a by a scale factor of 3, it will make it the same size as Circle B, showing that the two circles are similar.
Rotating and reflecting does nothing because both circles are in the same quadrant and rotating a circle does nothing to the placement.
Translating the circle (x+3, y-2) does not put it in the same place as circle B.
A flagpole stands perpendicular to the ground. It is supported by a 20-foot cable that runs from the top of the flagpole to the ground at a point that is 12 feet from the base of the pole. Find the height of the flagpole. The Pythagorean theorem is a2 b2
Answer:
h = 16 feet
Step-by-step explanation:
Pythagoras´ theorem establishes, that in a right triangle square of the hypothenuse (c²) is the sum of leg ( b²) plus leg (a²)
Then
c² = a² + b²
where according to the problem statement
(20)² = h² + (12)² ( h is the height of the flagpole )
h² = 400 - 144
h² = 256
h = √ 256
h = 16 feet
Working alone, it would take Shandra 40 minutes to sand a table. To sand the same table, also working alone, it would take Kelly 1 hour. If they work together, the situation can be modeled by the following equation, where t is the time it would take to sand the table working together.

Shandra claims it will take them about 50 minutes working together, because 50 is the mean of 40 and 60. Which best describes Shandra’s claim?
Answer: CCCCCC
Step-by-step explanation:
It would take 24 minutes to sand the table working together.
What is an Equation?An equation is used to show the relationship between two or more variables and numbers.
It would take Shandra 40 minutes (2/3 hours) to sand a table while it would take kelly 1 hour.
Let t be the time it would take to sand the table working together. Hence:
(1/(2/3) + 1/1)t = 1
(3/2 + 1)t = 1
2.5t = 1
t = 0.4 hours = 24 minutes
It would take 24 minutes to sand the table working together.

Find the volume of the triangular prism:
-27yd^3
-72yd^3
-240yd^3
-360yd^3
Answer:
B. 72 yd^3
Step-by-step explanation:
First we find the area of the base, which is the triangle.
Area = (1/2)(base)(height)
A = 1/2(3)(8) = 1/2(24) = 12
Multiply that base area by the height (6)
12 x 6 = 72

All day laborers of a large manufacturing company receive a 2% raise every 6 months. The current mean hourly wage earned by the all day laborers is $9.75 per hour and the standard deviation of their hourly wages is $0.87 per hour. Assuming that the raise rate and frequency remain the same, what will the mean and standard deviation of the hourly wages earned by day laborers be 2 years from now
Answer:
[tex]\=x'=\$10.55[/tex]
[tex]\sigma'=10.55[/tex]
Step-by-step explanation:
From the question we are told that:
Raise[tex]r=2\%[/tex] at Time interval 6 months
Time [tex]t=2 years[/tex]
Mean hourly pay [tex]\=x=$9.75[/tex]
Standard deviation[tex]\sigma=\$0.87[/tex]
Generally the equation for mean is mathematically given by
[tex]\=x=P*(1+r)^n[/tex]
Where
[tex]P=Principle\ mean[/tex]
[tex]n=number\ of\ intervals[/tex]
[tex]n=2years/6months[/tex]
[tex]n=4[/tex]
Therefore
[tex]\=x'=9.75*(1+0.02)^4[/tex]
[tex]\=x'=\$10.55[/tex]
Generally the equation for Standard deviation is mathematically given by
[tex]\sigma'=P'*(1+r)^n[/tex]
Where
[tex]P'=Principle\ Standard\ deviation[/tex]
Therefore
[tex]\sigma'=0.87*(1+0.02)^4[/tex]
[tex]\sigma'=10.55[/tex]

Step-by-step explanation:
The short arc where two tangents intersect a circle, and the angle where the tangents meet are supplementary.
__
15) ? = 180° -55° = 125°
16) ? = 180° - 80° = 100°

Additional comment
The quadrilateral formed by the tangents and the radii to the points of tangency has a total interior angle measure of 360°. The angles where the radii meet the tangents are 90°, so the sum of the external angle and the central angle is 360° -90° -90° = 180°. That is, the external angle and the central angle are supplementary.

Find the sum of the angle measures in a regular polygon.
A) 720*
B) 900*
C) 1080*
D) 1260*
Please help!! Thanks
Answer:
D) 1260°
Step-by-step explanation:
In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.
Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°
You can easily confirm that it works for triangles and quadrangles ;)
The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°
1260°

At time t = 0 hours, a tank contains 2000 litres of water.
Water leaks from the tank.
At the end of every hour there is x% less water in the tank,
than at the start of the hour.
The volume of water, in litres, in the tank at time t hours is V.
Given that
V = k'V
V. = 1714.75
work out the value of k and the value of x.
Answer:
k= 0.95
x = 5
Step-by-step explanation:
V₀=2000 because at the start (when t=0), there's 2000l in the tank.
V[tex]_{t}[/tex]=[tex]k^{t}[/tex]V₀
V[tex]_{t}[/tex]=2000[tex]k^{t}[/tex]
V₃=1714.75=2000k³
k³=0.857375
k= 0.95
-----
V[tex]_{t}[/tex]=2000[tex]k^{t}[/tex]
V[tex]_{t}[/tex]=2000[tex](0.95^{t})[/tex]
V₁=2000(0.95)=1900
So from V₀ to V₁, the tank loses 100l, which is 5% of it's volume at the start of the hour (100/2000=5%). Therefore x = 5

Answer:
The last one: 70/100 = x/80
And 56 free throws.
Explanation:
70% is 70 out of 100. And if the player is free throwing a total of 80 times, then 80 is 100% of the free throws. Both of the values that represent 100% are the denominators in the fractions.
[tex]\frac{70}{100} = \frac{x}{80}[/tex]
The equations are equal, and whatever you do to the bottom, you have to do to the top. 100 was multiplied by 4/5 to get 80. So 70 is multiplied by 4/5 to get x.
4/5 * 70 is 56

A manager needs to order company shirts for each employee. She was quoted the following rates. If she orders 75 shirts and passes the cost along to the employees, what would each employee owe for the shirt if each pays the same amount? Round to the nearest cent. Price Quote for Company Work Shirts Number of shirts ordered Cost per shirt First 19 shirts $10 Next 30 shirts $8 Each shirt over 49 $5 $7.40 $7.47 $7.53 $7.66
Answer:
The answer is $7.47.
Step-by-step explanation:
calculate how much in total 75 shirts cost:
- first 19 (less than 20) cost $10: 19 * $10 = $190
- the next 30 cost $8: 30 * $8 = $240
- the rest (26 = 75 - 19 - 30) cost $5: 26 * $5 = $130
in total 75 shirts cost $560:
19 * $10 + 30 * $8 + 21 * $5 = $190 + $240 + $130 = $560
Since 75 shirts are ordered, there must be 75 employees, so each employee must pay $7.47:
$565 ÷ 75 = $7.47
Answer:
$7.47

A bag contains 20 slips of paper Individually numbered. If a slip of paper and a letter in the word PENNSYLVANIA is chosen at randomfind each probability.
Answer:
[tex]P(M4\ n\ V) = 2.083\%[/tex]
Step-by-step explanation:
Given
Paper = 20 slips
Word: PENNSYLVANIA
Required
Determine P(Multiple of 4 and V)
The sample size of the 20 slips is:
[tex]n(S) = 20[/tex]
The outcomes of multiples of 4 is:
[tex]M4= \{4,8,12,16,20\}[/tex]
[tex]n(M4) = 5[/tex]
So, the probability of multiples of 4 is:
[tex]Pr(M4) = \frac{5}{20}[/tex]
[tex]Pr(M4) = \frac{1}{4}[/tex]
The sample size of PENNSYLVANIA is:
[tex]n(S) = 12[/tex]
The outcome of V is:
[tex]n(V) = 1[/tex]
So, the probability of V is:
[tex]P(V) = \frac{1}{12}[/tex]
So, the required probability is: P(Multiple of 4 and V)
[tex]P(M4\ n\ V) = P(M4) * P(V)[/tex]
[tex]P(M4\ n\ V) = \frac{1}{4} * \frac{1}{12}[/tex]
[tex]P(M4\ n\ V) = \frac{1}{48}[/tex]
[tex]P(M4\ n\ V) = 0.02083[/tex]
Express as percentage
[tex]P(M4\ n\ V) = 0.02083 * 100\%[/tex]
[tex]P(M4\ n\ V) = 2.083\%[/tex]
