Rupert is copying some files from his computer to a compact disc, like the one shown above.
If the diameter of the compact disc is 120 millimeters, what is the approximate area ignoring the center hole? (Use 3.14 for pi.)
A.
376.8 mm2
B.
11,304 mm2
C.
753.6 mm2
D.
45,216 mm2
Option B: [tex]11,304 \mathrm{mm} ^2[/tex] is the area of the compact disc.
Explanation:
The diameter of the compact disc is [tex]120mm[/tex].
To determine the area of the compact disc, let us substitute the values in the area of the circle formula,
[tex]A=\pi r^2[/tex] where [tex]r=\frac{d}{2}[/tex]
Substituting the value of d in [tex]r=\frac{d}{2}[/tex], we get,
[tex]r=\frac{120}{2} =60[/tex]
Thus, [tex]r=60[/tex] and [tex]\pi=3.14[/tex]. Let us substitute these values in [tex]A=\pi r^2[/tex], we get,
[tex]A=3.14\times(60)^2[/tex]
Simplifying, we have,
[tex]A=3.14\times3600[/tex]
Multiplying, we get,
[tex]A=11304mm^2[/tex]
Thus, the area of the compact disc is [tex]11,304 \mathrm{mm} ^2[/tex]
Hence, Option B is the correct answer.
How many cube-shaped boxes with 12-inch edges can fit into a box thatis 4
feet tall, 4 feet long, and 5 feet wide?
Answer:
80
Step-by-step explanation:
First recall that:
1 inch=12 feet
The volume of cube-shaped boxes with 12-inch edges is 1 cm³
The volume of a box that is 4
feet tall, 4 feet long, and 5 feet wide is
given by:
[tex]Volume = lwh[/tex]
We substitute l=4ft, w=5ft and h=4ft
To obtain:
[tex]Volume = 4 \times 4 \times 5 = 80 {ft}^{3} [/tex]
Therefore 80 cube-shaped boxes with 12-inch edges can fit into a box that is 4
feet tall, 4 feet long, and 5 feet wide.

A principal of 3700 is invested at 4.75 %interest, compounded annually. How much will the investment be worth after 5 years?
The investment will be worth $4686.62 after 5 years.
Step-by-step explanation:
Principal, P = 3700
Rate, r = 4.75% = 0.0475
Number of years, t = 5 years
Number of times compounded, n = 5 times
Amount = P(1 + r/n)^nt
⇒ 3700 (1 + 0.0475/5)^25
⇒ 3700 (5.0475/5)^25
⇒ 3700 (1.0095)^25
⇒ 4686.62
∴ Amount = $4686.62
Which table values can be defined by the function y=2x+3

How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 30% antifreeze to get a mixture that is 40% antifreeze?
Answer:
70 gallons
Step-by-step explanation:
x gallon of 50%
x * 0.5 + 70 * 0.3 = (x + 70) * 0.4
0.5x + 21 = 0.4x + 28
0.1x = 7
x = 70
To get a mixture that is 40% antifreeze, we need to mix 70 gallons of 30% antifreeze solution with 40 gallons of 50% antifreeze solution. This conclusion is reached by establishing an equation representing the total amount of antifreeze in the mixture before and after and then solving for the unknown.
Explanation:Your question deals with the concept of a weight ratio in a chemical mixture. Specifically, we're going to solve it using algebra. Let's say you need x gallons of the 50% antifreeze solution. We can work this out by forming an equation based on the information given in the problem:
The total amount of antifreeze in the 70 gallons of 30% solution and x gallons of 50% solution must be equal to the total amount of antifreeze in the (70 + x) gallons of 40% solution.
Therefore, we can write: 0.3 * 70 + 0.5 * x = 0.4 * (70 + x)
Solving the equation above, we find that x equals 40 gallons. So, you would need to mix 40 gallons of a 50% antifreeze solution with 70 gallons of 30% solution to obtain a final solution with a 40% antifreeze concentration.

Little help!!!!!
Answer:
Step-by-step explanation:
as the temp t increases the number of cricket chirps also increases.
1: The complete table is according to the given function :
t : 40 50 60 70 80 90 100
c : 10 50 90 130 170 210 250
2: It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.
The given function is,
c = 4t - 180
Here t represents the temperature
c represents the cricket chirps per minutes
Now plug in each temperature value and solve for c:
When t = 40:
c = 4(40) - 150
c = 160 - 150
c = 10
When t = 50:
c = 4(50) - 150
c = 200 - 150
c = 50
When t = 60:
c = 4(60) - 150
c = 240 - 150
c = 90
When t = 70:
c = 4(70) - 150
c = 280 - 150
c = 130
When t = 80:
c = 4(80) - 150
c = 320 - 150
c = 170
When t = 90:
c = 4(90) - 150
c = 360 - 150
c = 210
When t = 100:
c = 4(100) - 150
c = 400 - 150
c = 250
Therefore, the complete table is:
t : 40 50 60 70 80 90 100
c : 10 50 90 130 170 210 250
When the value of t is 60, the value of c is 90.
It means when the temperature is 60 Fahrenheit then the number of cricket chirps is 90 per minute.

Find the area of the triangle below. Show as much work as possible. Label your answer appropriately.
Answer:
[tex]Area=\frac{5}{12}x^2[/tex]
Step-by-step explanation:
The area of a triangle is given by:
[tex]Area=\frac{1}{2}*base*height[/tex]
From the diagram [tex]base=\frac{5}{6}x,and,height=x[/tex]
We substitute into the formula to get:

a paddling canoeist took 2 h to travel 12 km down a river, with the current. It took 4 h to do the return trip up the river, against the current. What was the speed of the current
Answer: The speed of the current is 1.5 km/h .
Step-by-step explanation:
Let x = speed of current and y = speed of canoe.
Since , [tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
As per given , we have
[tex]x+y=\dfrac{12}{2}\\\\ x+y=6......................(1)[/tex]
[tex]y-x=\dfrac{12}{4}\\ y-x=3...............(2)[/tex]
Adding (1) and (2) , we get
[tex]2y=9\\\Rightarrow\ y=\dfrac{9}{2}=4.5[/tex]
Put value of y in (1) , we get
[tex]x+4.5=6\\\Rightarrow\ x=1.5[/tex]
Hence, the speed of the current is 1.5 km/h .
To find the speed of the current, we can use the concept of relative velocity and set up equations for the downstream and upstream journeys.
Explanation:In order to find the speed of the current, we can use the concept of relative velocity. Let's assume the speed of the canoeist in still water is 'v' km/h and the speed of the current is 'c' km/h.
Downstream journey: The effective speed of the canoeist is 'v + c' km/h. Given that the canoeist took 2 hours to travel 12 km downstream, we can set up the equation:
(v + c) * 2 = 12
Upstream journey: The effective speed of the canoeist is 'v - c' km/h. Given that the canoeist took 4 hours to travel 12 km upstream, we can set up the equation:
(v - c) * 4 = 12
Solving these two equations simultaneously will give us the values of 'v' and 'c', and the value of 'c' will represent the speed of the current.

Carle is cutting pieces of string that are exactly 24 3/8 inches long. How many pieces can she cut from a ball of string that has 100 feet
49 pieces of string can be cut from a ball of string that has 100 feet
Solution:
Given that, Carle is cutting pieces of string that are exactly 24 3/8 inches long
Therefore,
[tex]Length\ of\ each\ string = 24\frac{3}{8}\ inches = \frac{8 \times 24 + 3}{8} = \frac{195}{8}\ inches[/tex]
How many pieces can she cut from a ball of string that has 100 feet
Total length of string = 100 feet
Convert feet to inches
1 feet = 12 inch
100 feet = 1200 inch
Therefore, number of pieces that can be cut is given as:
[tex]\text{Number of pieces } = \frac{\text{total length of string}}{\text{length of each string}}[/tex]
Substituting the values we get,
[tex]\text{Number of pieces } = \frac{1200}{\frac{195}{8}}\\\\\text{Number of pieces } = 1200 \times \frac{8}{195}\\\\\text{Number of pieces } = 49.2307 \approx 49[/tex]
Therefore, 49 pieces of string can be cut from a ball of string that has 100 feet

60
3) 2x + 65 + 3x + 40 = 180 The angles add up to 180 degrees
5x + 105 = 180 Combine like terms
- 105 - 105 Subtract 105 from both sides
5x = 75 Divide both sides by 5
x = 15
Plug in 15 into both equations
2(15) + 65 = 95
3(15) + 40 = 85
4) 5x + 38 = 9x - 10
- 5x - 5x Subtract 5x from both sides
38 = 4x - 10
+ 10 + 10 Add 10 to both sides
48 = 4x Divide both sides by 4
12 = x
Plug in 12 into both equations
5(12) + 38 = 98
9(12) - 10 = 98
