11. What is the RADIUS of ONE circle? Find the AREA of the figure.
Hint: (the circles are congruent)
Answers
Answer:
258.41 m
Step-by-step explanation:
Since there are three semi-circles in the length of the rectangle, we can divide 18 by 3 to get 6 as the diameter for each circle. The area of a semi-circle is (pi*r^2)/2, we can multiply that by 3 and add it with the area of the rectangle to get the total area.
(12*18) + (3(pi*3^2))/2 =
216 + 42.4115 =
258.41 m

if a system of linear equations has infinitely many solutions, what does this mean about the two lines?

Cheyenne's car is in the shop, so she needs to rent a car for 4 days. The cost of a rental car is $24.99 per day, and she will be charged $0.18 per mile for every mile she drives over 200 miles. If she drives 300 miles and the sales tax she pays on the rental is 5.5%, how much will she pay for this rental?
1) Find the cost to rent the car for 4 days.
2) How many miles did Cheyenne drive over 200 miles? Remember to look at the difference between the total miles driven and the miles over 200.
3) Find the cost for miles over 200.
4) Find the total cost including the cost to rent and the cost for miles.
5) Find the total with tax. The multiplier is 1.055

Judy is selling small candles at the fair for $4 each and large candles for $6 each. She collected $144 selling a total of 28 candles. How many of each candle did she sell? Use x for the small candles and y for the large candles.
small candle x= blank candles
large candle y = blank candles
Answers
Answer:
Number of small candles = 12
Number of large candles = 16
Step-by-step explanation:
Total candles = 28
x + y = 28 ---------------(I)
Cost of 'x' small candles = 4 *x = 4x
Cost of 'y' large candles = 6 *y = 6y
Total amount = $144
4x + 6y = 144 -------------(II)
Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'
(I) * (-4) -4x - 4y = -112
(II) 4x + 6y = 144 {Now, add}
2y = 32
y = 32/2
y = 16
Plug in y = 16 in equation (I)
x + 16 = 28
x = 28 - 16
x = 12
Answer:
small candles-x
large -y
144-4x=6y
28-x=y
28-y=x
(28-x)6+4x=144
168-6x+4x=114
-2x=-54
2x=54
x=27

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 4 minutes and 18 minutes. What is the probability that it takes Isabella more than 7 minutes to wait for the bus
Answers
Answer:
0.25 or 25% probability
Step-by-step explanation:
The lower limit in this question = a
The upper limit = b
P(X<=x) = x-a/b-a
a = 4
b = 8
The question says it is uniformly distributed between 4 minutes and 8 minutes
Probability that it takes her more than 7 minutes to wait for the bus
P(X<=7) + P(X>7)= 1
We are to get P(X>7)
= 1 - (7-4/8-4)
= 1-3/4
= 1-0.75
= 0.25
= 25% probability it takes her more than 7 minutes to wait

1. Sand falling from a chute forms a conical pile whose altitude is always equal to 4/3 the radius of the base. (a) How fast is the volume increasing when the radius of the base is 3 ft and is increasing at a rate of 3 in/min
Answers
Answer:
The volume is increasing at a rate of 16286 in³/min.
Step-by-step explanation:
a) The volume of a cone is given by:
[tex] V = \frac{1}{3}h\pi r^{2} [/tex]
Where:
r: is the radius
h: is the height
The rate of change of the volume can be calculated by using the chain rule:
[tex] \frac{dV}{dt} = \frac{\pi}{3}[\frac{dh}{dt}r^{2} + h\frac{d(r^{2})}{dt}] [/tex]
Since h = 4/3 r we have:
[tex] \frac{dV}{dt} = \frac{\pi}{3}[\frac{d(\frac{4r}{3})}{dt}r^{2} + \frac{4r}{3}\frac{d(r^{2})}{dt}] [/tex]
[tex] \frac{dV}{dt} = \frac{4\pi}{9}[\frac{dr}{dt}r^{2} + r\frac{d(r^{2})}{dt}] [/tex]
[tex] \frac{dV}{dt} = \frac{4\pi}{9}[\frac{dr}{dt}r^{2} + 2r^{2}\frac{dr}{dt}] [/tex] (1)
With:
[tex]\frac{dr}{dt}[/tex] = 3 in/min
[tex]r = 3 ft*\frac{12 in}{1 ft} = 36 in[/tex]
And by entering the above values into equation (1) we have:
[tex] \frac{dV}{dt} = \frac{4\pi}{9}[(3 in/min)*(36 in)^{2} + 2*(36 in)^{2}*3 in/min] [/tex]
[tex]\frac{dV}{dt} = 16286 in^{3}/min[/tex]
Therefore, the volume is increasing at a rate of 16286 in³/min.
I hope it helps you!

Step 1: Define Systems
y = 2x - 7
5x + 2 = 4
Step 2: Solve for x
Define equation: 5x + 2 = 4Subtract 2 on both sides; 5x = 2Divide 5 on both sides: x = 2/5Step 3: Solve for y
Define equation: y = 2x - 7Substitute in x: y = 2(2/5) - 7Multiply: y = 4/5 - 7Subtract: y = -31/5The restaurant sold coffee and tea during the breakfast shift. The number of cups of tea they sold was 6 more than 1/3 of the number of cups of coffee sold. If the total cups of coffee and tea sold was 70, how many cups of each were sold?
Answers
Answer:
cups of tea = 22
cups of coffee = 48
Step-by-step explanation:
c = coffee
t (tea) = 6 + 1/3c
t + c = 70
c + 6 + 1/3c = 70
4/3c + 6 = 70
4/3c = 64
4c = 192
c = 48
t = 70 - 48 = 22
