(5 points) Group of answer choices Worker at $10 per hour, producing eight pounds of candy per hour Worker at $12 per hour, producing 16 pounds of candy per hour Machine with $5 per hour operating cost, producing 10 pounds of candy per hour Machine with $8 per hour operating cost, producing 14 pounds of candy per hour
Then the most profitable investment is the first machine (third option) because for each dollar, it produces 2 pounds of candy.
Which of the following is the most profitable investment?The first option is a worker that costs $10 per hour and produces 8lb, then this worker gives:
8lb/$10= 0.8 pounds per dollar.
The second worker costs $12 per hour, and produces 16lb per hour, so this worker gives:
16lb/$12 = 1.33 pounds per dollar.
The third option is a machine that cost $5 per hour and produces 10lb per hour, then:
10lb/$5 = 2 pound per dollar.
The last option costs $8 per hour, and produces 14 pounds per hour, then:
14lb/$8 = 1.75 pounds per dollar.

The ratios for the surface area, volume and width respectively are:
Ratio of SA = 9:196.Ratio of V = 27:2,744.Ratio of W = 3:14.What is ratio?Ratio can be defined as a mathematical expression that's used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.
In this exercise, we are given the scale factor for this canoe is 3:14. Thus, the ratio of the surface area of the canoe model to the surface area of the original model would squared as follows:
Ratio of SA = 3²/14²
Ratio of SA = 9/196
Ratio of SA = 9:196.
For the volume, we would take the cube:
Ratio of V = 3³/14³
Ratio of V = 27/2,744
Ratio of V = 27:2,744.
For the width, we have:
Ratio of W = 3/14
Ratio of W = 3:14.

Answer:
D
Step-by-step explanation:
Converting percent to decimal : 2.2/100 = 0.022
Finding 2.2$ of $75k : 75,000 x 0.022 = $1,650 (also the increase in one year)
Finding how much it was worth after 11 years :
(75,000 x 0.022) x 11 = $18,150 or 1,650 x 11 = $18,150
Now add the product to the regular amount to find out the answer:
75,000 + 18,150 = $93,150 (which is how much it increased after 11 years)

Answer:
b = 5.3
A = 48.6
B = 41.4
Step-by-step explanation:
Attached is the Pics contain the Pythagoras Theorem and Trigonometric Identities.
So for our Right-Angled Triangle we have from Pythagoras Identity that
[tex]a^{2} +b^{2} =c^{2}[/tex] ,, Then [tex]b^{2} =c^{2} -a^{2}[/tex] where a=6 , c=8
by substituting,
[tex]b^2=8^2-6^2=28\\ b=\sqrt{28} =2\sqrt{7}=5.3[/tex]
Now to find A , we will use the Trigonometric Identities
Since [tex]sin(A)=\frac{Opposite}{Hypotenuse}=\frac{a}{c} =\frac{6}{8}=\frac{3}{4} \\[/tex]
[tex]A=sin^{-1} (\frac{3}{4} )=48.6\\[/tex]

The junior class sold 75% of the raffle tickets. They started with 100 raffle tickets.
How many tickets have been sold?
Answer:
75
Step-by-step explanation:
Since they sold 75% of the raffle tickets and the total is 100 raffle tickets, you simply need to find 75% of 100. To find x% of a, you simply convert x% to a decimal by dividing by 100 and then multiplying it by a. So the general formula to find x% of a would be: [tex]a*\frac{x}{100}[/tex]. In this case a=100, and x=75. So you have the equation: [tex]100*\frac{75}{100} = \frac{100 * 75}{100}=\frac{75}{1} = 75[/tex]
Answer: 75 tickets
Step-by-step explanation:
- percentages are out of 100, they are a rate, number, or amount in each hundred
- for example, (10/100) x 100 (because it’s out of 100) = 10%
- or it could be (6/40) x 100 (because it’s out of 100) = 15%
- so because they started with 100 tickets, it’s just (75/100) x 100 =75

d. Angle XAB is congruent to angle XCD.
=
DX
CX
In the triangle, the fact that wee are given 2AX = 3XD isn't enough to prove similarity.
How to explain the triangle?a. In the question, we are given 2AX = 3XD. An arbitrary triangle AXB can be drawn where one extends AX and choose a point D on the extended line in order for 2AX = 3XD. Also, extend BX and choose a point C on the line so that 2BX = XC. Even though they both satisfy the condition, they're not similar.
b. We are given that AX/BX = DX/CX. When this is rearranged, we'll have AX/DX = BX/CX. In this case, let AX/DX = k. DX and AX will align upon rotation of 180°. The triangle can then be dilated by a factor of k. This brings about the mapping of triangle DXC to AXB. Therefore, the original triangle DXC is similar to AXB.
c. Lines AB and CD are parallel. Here, the dilation moves line CD onto line AB. Here, since the dilation moves D to a point on ray XA, D must move to A. Therefore, the rotation of triangle DXC is similar to AXB. Therefore, DXC is similar to AXB.
d. Here, angle XAB is congruent to angle XCD. This shows similarity and in this case, XCD is similar to XAB.

What is the Law of Cosine?The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,

c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
The length of the sidelink b using the cosine rule can be written as,
[tex]b = \sqrt{a^2+c^2-2ac\cos(\angle B)}\\\\b = \sqrt{4^2+5^2 - 2(4)(5)(\cos 60^o)}\\\\b = \sqrt{16+25-20}[/tex]

If an object moves along the y-axis (marked in feet) so that it’s position at time X (in seconds) is given by f(x) = 108x -12x^2 , find the following:
The velocity equation is:
[tex]v(x) = 108 - 24x[/tex]
Such that:
[tex]v(0) = 108 ft/s\\v(2) = 60ft/s\\[/tex]
And the velocity is zero for x = 4.5
How to find the velocity equation?
We know that the position equation is:
[tex]f(x) = 108*x - 12*x^2[/tex]
To get the velocity, we need to differentiate with respect to x, so we get:
[tex]v(x) = \frac{df(x)}{dx} = 108 - 2*12*x = 108 - 24*x[/tex]
Now we want to get the velocity for x = 0 and x = 2, we will get:
[tex]v(0) = 108 - 24*0 = 108\\\\v(2) = 108 - 24*2 = 60[/tex]
Then, when x = 0, the velocity is 108 ft/s, when x = 2 the velocity is 60 ft/2.
Finally, we need to solve:
[tex]v(x) = 108 - 24*x = 0\\\\x = 108/24 = 4.5[/tex]
