Lynh manages a small company with 12 employees. He offers profit sharing where 5% of profits at end of year is distributed evenly to the employees. Each employee earned $2,300 in profit sharing in 2013. What was the total profit?

Answers

We need to find the total profit of Lynh Mangoes. It is given that the 5 % of profit to be distributed equally between 12 employees.

Profit received by each employee = $ 2,300

Total profit received by 12 employees = $ 2,300 × Profit received by each employee

Total profit received by 12 employees = $ 27,600

It is given that 5 % to be distributed.

Thus, 5 % of total profit = $ 27,600

Total profit = $ 27,600 ÷ 5 %

Total profit = $ 552,000

A child is standing at point c and flying a kite located at point a, 25 ft above the ground. as the child lets out more string, the kite rises to a point b, directly above point
a. if the angle of elevation changes from 50º to 65º, how much higher to the nearest foot, is the kite than it was initially?

Answers

Final answer:

To calculate the height increase of the kite, we can use trigonometry and the formula tan(angle) = h / distance. By plugging in the values, we find that the kite is approximately 25 * tan(65º) ft higher than it was initially.

Explanation:

To find how much higher the kite is than it was initially, we need to determine the difference in height between points a and b. Since point b is directly above point a, the difference in height can be calculated using trigonometry.

We can use the tangent of the angle of elevation to find the height increase. The tangent of an angle is equal to the opposite side divided by the adjacent side.

In this case, the opposite side is the height increase (h) and the adjacent side is the distance between points a and c. We can use the formula tan(angle) = h / distance to solve for h.

Given that the angle changes from 50º to 65º, we can calculate the height increase as follows:

tan(65º) = h / distance

Solving for h:

h = tan(65º) * distance

Plugging in the values:

h = tan(65º) * distance

h ≈ tan(65º) * 25 ft

Rounding to the nearest foot, the kite is approximately 25 * tan(65º) ft higher than it was initially.

At the local grocer, the prices for apples are the following: 9 ounces for $1.89 or 1 pound for $2.49. How much will you save per pound, by buying the least expensive? Round to the nearest cent.

A.) $0.87
B.) $0.10
C.) $0.60
D.) $0.21

Answers

Answer: Option 'A' is correct.

Explanation:

Cost of 9 ounces of apples = $1.89

Cost of 1 ounce of apple is given by

[tex]\frac{1.89}{9}=\$0.21[/tex]

Now, if he bought 1 pound of apple,

Cost of 1 pound of apple = $2.49

Cost of 16 ounces = $2.49

(∵ 1 pound = 16 ounces)

Cost of 1 ounce of apple is given by

[tex]\frac{2.49}{16}=\$0.156[/tex]

So, Second option is the least expensive if he bought 1 pound of apple for $2.49

Then, he will save which is given by

[tex]0.21-0.156=0.054\times 16=$0.87\ per pound[/tex]

Hence, option 'A' is correct.

Final answer:

You will save $0.87 per pound by purchasing apples at the price per pound rate ($2.49) compared to the 9-ounce rate ($1.89 for 9 ounces), with the savings calculated by converting the 9-ounce price to a per pound rate and comparing it to the given per pound price.

Explanation:

To determine how much you will save per pound by buying the least expensive option for apples, first convert the price for 9 ounces into the equivalent price per pound. Since there are 16 ounces in a pound, you need to calculate the price per ounce and then multiply by 16 for the pound equivalence. The price per ounce for the first option is $1.89/9 ounces = $0.21 per ounce. Hence, the price per pound would be $0.21 per ounce × 16 ounces/pound = $3.36 per pound.

Now compare the price per pound of both options. The specified price per pound is $2.49, and the calculated price per pound for the 9-ounce option is $3.36. The savings per pound when buying the least expensive option ($2.49 per pound) would be $3.36 - $2.49 = $0.87 per pound, rounded to the nearest cent.

Therefore, the correct answer is (A) $0.87.

Add. Express your answer in lowest terms. 8 3/10 + 7 2/15

Answers

[tex]= 8 \dfrac{9}{30} + 7 \dfrac{4}{30} [/tex]

[tex]=15 \dfrac{13}{30} [/tex]

Final answer:

To add 8 3/10 and 7 2/15, we need to find a common denominator. The sum is 15 1/15.

Explanation:

To add 8 3/10 and 7 2/15, we need to find a common denominator. The least common multiple of 10 and 15 is 30. So we convert both fractions to have a denominator of 30: 8 3/10 = 8 9/30 and 7 2/15 = 7 4/30. Now we can add the whole numbers and the fractions separately:

8 + 7 = 159/30 + 4/30 = 13/30

Combining the results, the sum is 15 13/30. To express the answer in lowest terms, we can simplify the fraction: 13 and 30 are both divisible by 13, so dividing both by 13 gives us 1 and 2/30. Therefore, the final answer is 15 2/30, which can be further simplified to 15 1/15.

Is quadrilateral JKLM the result of a dilation of quadrilateral ABCD by a scale factor of 2? Why or why not? Yes, because sides JK and ML are twice as long as sides AB and DC. Yes, because both figures are parallelograms, so corresponding sides are parallel. No, because sides JK and ML are not twice as long as sides AB and DC. No, because sides JM and KL have different slopes from sides AD and BC.

Answers

Answer:

(d) No, because sides JM and KL have different slopes from sides AD and BC

Step-by-step explanation:

You want to know if quadrilateral JKLM is a dilation of ABCD by a factor of 2, and why or why not.

Dilation

Dilation multiplies the distance of each point on the figure from the center of dilation by the scale factor. Dilation by a scale factor of 2 will move JKLM twice as far from the origin as ABCD. This preserves slopes and angles, but changes lengths by the scale factor.

In the given figure, ABCD is 2 units wide and 2 units high. If JKLM is a dilation by a factor of 2, it will be 4 units wide and 4 units high.

JKLM is 5 units high, so is not a dilation. JK and ML are twice as long as AB and DC, so choice C is not an appropriate explanation.

Sides JM and KL have different slopes from sides AD and BC, choice D.

Additional comment

The slopes of JM and KL are 5/2. The slopes of AD and BC are 2/1, a different value.

Answer: D

ommy Teacher wants to analyze the weights of the students at his school. He knows the weight of the students is normally distributed so he can use the standard normal distribution. He measures the weight of 100 randomly selected students in the school. He finds the mean is 80 pounds and the standard deviation is 8 pounds.

Out of 100 students, how many should weigh between 64 and 96 pounds?

Answers

We first determine the z-scores for the given x-values of 64 and 96.
For x = 64: z = (64 - 80) / 8 = -2
For x = 96: z = (96 - 80) / 8 = 2
Therefore we find the probability that -2 < z < 2, which is around 0.95. Therefore, out of 100 students, approximately 100(0.95) = 95 students will weigh between 64 and 96 pounds.

check the picture below.

this is a case of the ambiguous case with an SSA, AC and CB are the sides and the angle is at A.

the ambiguous case has two triangles, the case when B is acute, CB sticks out, and the case when B is obtuse, CB sticks inside, it just so happen that those two angles for B are "supplementary" angles.

if you check the sin⁻¹ of that, we'll get the acute version of B, that's because of the constraints on the range of the inverse sine function, and we get ∡B ≈ 36.86989765°.

and of course, the other angle for B will be 180 - 36.86989765.

What is the exact value of cos 30° ?

Answers

Consider a ΔABC in which ∠ C = 90°, ∠A = 60° and ∠ B = 30°.

Side AB will be the hypotenuse.

cos 60° = AC / AB -------[ cos 60° = 1/2]

So, AB = 2 AC -------------------------------(1)

Apply Pythagorean Theorem to find BC

AB² = BC² + AC²

4 AC² = BC² + AC²

So, BC = √3 AC ------------------------(2)

Now, we shall find the value of cos 30°

cos 30° = CB / AB

or, = √3 AC / 2 AC -------using equations (1) and (2)

So, cos 30° = √3 / 2

Hence, the exact value of

Since ∠A = 2∠B. So, cos 30° will be √3 / 2

Answers

we have that
Point R is located at (–1, 3), and point S is located at (3, 1)

we know that
the perpendicular bisector of RS go through the midpoint of RS

step 1

find the midpoint RS

midpoint M (Mx,My)
Mx=(x1+x2)/2
My=(y1+y2)/2

Mx=(-1+3)/2------> Mx=1
My=(3+1)/2-------> My=2

the midpoint M is (1,2)

step 2
find the slope RS
m=(y2-y1)/(x2-x1)-------> m=(1-3)/(3+1)-----> m=-2/4-----> m=-1/2

we know that two lines are perpendicular if the slopes
m1*m2=-1

step 3
find the slope of the perpendicular bisector of RS
m2=-1/m1------> m2=2

step 4
with m=2 and the midpoint M (1,2) find the equation of a line

y-y1=m*(x-x1)------> y-2=2*(x-1)----> y=2x-2+2-----> y=2x

the answer is
