Find the area of each figure. Round your answer to 2 decimal places is required.
69.82 i think
Step-by-step explanation:
First the area of a rectangle is bh, so 5 times 12 is 60. Then you have a semicircle which is half a circle, so it would be pi(radius)squared divided by 2. The diameter is 5 because it's five on the other side and rectangles have opposite sides congruent. Radius is 2.5 after dividing diameter by 2. 2.5 pi r squared is like 19.634 blah blah blah. Divide that by two and add 60 to get 69.82.

Answer:
We cannot agree with Andre because x = 3.
Step-by-step explanation:
Assuming the diagram is a weighing scale which can also be represented as an equation having two sides that is balanced. We can express the situation as follows using equation:
x + 2 = 5
Solve for x
x + 2 - 2 = 5 - 2 (subtraction property of equality)
x = 3
If you plug in the value of x on the diagram given, the scale becomes balance on each side.
Therefore, x = 3. Andre is wrong and we cannot agree with Andre.
The scatter plot below shows the change in the demand for a pair of jeans at a store as the price changes. The sales manager uses y= -1.75x+92.13 as a line of best fit.
What is the residual value when the price of jeans is $28.00?
A)−9.37
B)−1.13
C)1.13
D)9.37
Answer:
1.13
Step-by-step explanation:
The residual value when the price of jeans is $28.00 is -15.13
How to determine the residual?The equation of the line of best fit is:
y= -1.75x+92.13
When the price of jeans is $28.00, we have:
y= -1.75*28+92.13
Evaluate
y= 43.13
The residual value is then calculated as:
Residual = Actual - Observed
This gives
Residual = 28.00 - 43.13
Evaluate the difference
Residual = -15.13
Hence, the residual value when the price of jeans is $28.00 is -15.13

Step-by-step explanation:
A Customer Telephone Center receives 1,200 calls in a 24-hour period. Of these calls, 75% occur between 9:30 a.m. and 3:30 p.m., and calls are evenly distributed during this time. If each person handles 10 calls an hour, how many people are needed to handle calls during these hours
Divide Total time into two Time Periods. A regular Demand and a High Demand Time Period. Since 75% of the 1,200 calls occur between 9:30 am and 3:30 pm. We multiply .75 x 1,200 to get 900. We get an average of 900 calls every day between the hours of 9:30 am and 3:30 pm – Our net time for this time period is 6 hours.
Therefore, 6 Hours/900 becomes our quotient
Again, since the denominator is larger we invert it to 900 calls/6 Hours
To get a demand of 150 calls per hour.
We need to be able to handle 150 calls per hour.
So how Many Call Representatives are needed?
Again, our historical data tells us that each person can handle 10 calls an hour.
Therefore 150 calls per hour /10 Minutes = 15 Customer Service Representatives are needed during Peak Time!
Now, Subtract the Peak Hours from the 21 Hours Net Time Per day, gives us 15 Non-Peak hours we have to staff.

find the image of U'( -8 , 1) after a translation along < 2 , 0 > and a reflection in the x axis
U"( -6 , -1)
U"(6 , 1)
U"(6 , -1)
U"(-1 , 6)
Given:
The point is U'(-8,1).
It is translated along <2,0> and reflected across the x-axis.
To find:
The image of U'.
Solution:
The given point is U'(-8,1).
It is translated along <2,0> . So, the rule of translation is:
[tex](x,y)\to (x+2,y+0)[/tex]
[tex]U'(-8,1)\to U_1(-8+2,1+0)[/tex]
[tex]U'(-8,1)\to U_1(-6,1)[/tex]
Then, it is reflected across the x-axis. So, the rule of reflection is:
[tex](x,y)\to (x,-y)[/tex]
[tex]U_1(-6,1)\to U''(-6,-1)[/tex]
The image of U'( -8 , 1) is U''(-6,-1).
Therefore, the correct option is A.

Oil prices are projected to increase by 125% by next August. A quart of oil currently costs $1.25. What is the projected cost of a gallon of oil next August? Round your answer to the nearest hundredth.
Answer:$2.81
Step-by-step explanation:
1.25 is 100% of the price
125% + 100% = 225%
x = price by august
x = 225% (1.25)
225% = 2.25
2.25(1.25) = 2.8125 ≈ $2.81
Another way to see it:
=
225(1.25) / 100 = 2.8125

The Frill family and the Smith family go to the movies.
The Frill family buys 6 adult tickets and 2 child tickets for $124.
The Smith family buys 3 adult tickets and 5 child tickets for $100.
Find the prize of an adult ticket and the prize of a child ticket.
Step-by-step explanation:
Let a be the price of 1 adult ticket.
Let c be the price of 1 child ticket.
given,
[tex]6a + 2c = 124[/tex]
as equation 1,
and
[tex]3a + 5c = 100[/tex]
as equation 2.
Now we will solve for a and c using elimination method of simultaneous equations.
Now we multiply equation 2 by 2 to eliminate a and solve for c.
[tex]3a \times 2 + 5c \times 2 = 100 \times 2 \\ 6a + 10c = 200[/tex]
This new equation will be equation 3.
Now we will use equation 1 - equation 3 to eliminate a and solve for c.
[tex](6a - 6a) + (2c - 10c) = 124 - 200 \\ 0 + ( - 8c) = - 76 \\ - 8c = - 76 \\ c = - 76 \div - 8 \\ = 9.5[/tex]
Now substitute c into equation 2.
[tex]3a + 5(9.5) = 100 \\ 3a + 47.5 = 100 \\ 3a = 100 - 47.5 \\ 3a = 52.5 \\ a = 52.5 \div 3 \\ = 17.5[/tex]
Therefore one adult ticket will cost $17.50 and one child ticket will cost $9.50.

Yesterday I went to buy some ice cream because it was on sale for $0.73. While I was there I also wanted to buy some sprinkles to put on top and they were only $0.15! What a bargain!!!! Since everything was so cheap, I also thought that I might want to buy a water bottle that was $2. When I went up to the cashier, they told me that I owed $9. EXCUSE ME?!? I said to them “I thought you all had a sale today, why am I paying $9?.”
how much you should’ve been charged
Given statement Sale Pricing Confusion solution is :- You should have been charged $2.88, not $9.
Let's break down the costs:
Ice Cream: $0.73
Sprinkles: $0.15
Water bottle: $2.00
The total cost of these three items would be:
$0.73 + $0.15 + $2.00 = $2.88
According to the prices you mentioned, you should have been charged $2.88, not $9. If the cashier told you that you owed $9, it's possible that there was an error in their calculations or that they included other items in your bill. It's best to clarify the discrepancy with the cashier and ask for an explanation or correction.

Step-by-step explanation:
This rectangle is made up of two 30-60-90 right triangles, which have special properties that are worth memorizing for the future. Please see the attached picture.
Using this information, we can deduce that the top and bottom sides are equal to [tex]12\sqrt{3}[/tex].
From the properties of a rectangle we know that the right side is 12.
The diagonal is equal to [tex]12*2=24[/tex].
We can find the area by doing [tex]{12*12\sqrt{3}=144\sqrt{3}[/tex],
And the perimeter is equal to [tex]12+12+12\sqrt{3}+12\sqrt{3} =24+24\sqrt{3}[/tex]
