You sell 200 laptops per month at $499 per laptop. You sell 350 smartphones per month at $399 per phone. Which
generates more sales in dollars for you?

a) Laptops
b) Smartphones

Answers

Answer:

B) Smartphones

Step-by-step explanation:

In order to answer this question we need to find the total revenue for the laptops and smartphones.

Let's start with the laptops.

Given:

200 laptops/month$499 per laptop

To find the total revenue of all these laptops we need to multiply 200 by 499.

[tex](200) *(499) = 99,800[/tex]

Therefore, the total revenue of the laptops alone is $99,800.

Now, let's do the smartphones.

Given:

350 smartphones/month$399 per smartphone

To find the total revenue of all these smartphones we need to multiply 350 by 399.

[tex](350) * (399) = 139,650[/tex]

Therefore, the total revenue of the smartphones alone is $139,650.

Comparing the two revenues we see that the smartphones generate more sales in dollars.

Consider that a population of fruit flies grew in a 40-day experiment. Average rate of change: 9 flies/day. Find the average growth rate from day 30 to day05​

Answers

Answer: Average Growth Rate is 24.19%

Step-by-step explanation:

Given that;

Average rate of change = 9 flies/day

Average growth rate of change = ?

we can determine the average growth rate of change from the expression;

Average Annual Growth Rate = [((Present Value - Past Value)^1/N) - 1 ]  × 100%]

Now our present value; 30th day = 9 × 30 = 270

past value; 05th day = 9 × 05 = 45

the value of N = 30 - 5 = 25

so we substitute

Average Annual Growth Rate = [((270 - 45)^1/25) - 1 ]  × 100%]

=  ([1.2419 - 1) × 100]

= 24.19%

Therefore Average Growth Rate is 24.19%

Replacing the maximum value of the data set with a smaller number will also affect the mean. A:always B:sometimes C:never

Answers

Answer:

B: sometimes

Step-by-step explanation:

Let's look at two examples.

Example A.

2, 3, 5: mean is 3

Replace 5 with 1. Now you have 1, 2, 3: mean is 2.

In this case, it affected the mean.

Example B.

2, 3, 5: mean is 3

Replace 5 with 4. Now you have 2, 3, 4: mean is 3.

In this case, it did not affect the mean.

As you can see, replacing the maximum value of the data set with a smaller number may or may not change the mean.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=-16x^2+275x+127

Answers

Answer:

1308.6 feet

Step-by-step explanation:

Given is the quadratic equation

y= -16x^2 + 275x + 127

It has the maximum height at its vertex, x-coordinate of which is calculated by the formula:

x = -b/2ax = -275/2(-16) = 8.6 rounded to the nearest tenths

Calculating the highest point:

y = -16(8.6)^2 + 275(8.6) + 127 = 1308.6 feet rounded to the nearest tenths

*Determine which student created a better line of best fit given the data in the graph. ​

Answers

Answer:

Step-by-step explanation:

im pretty sure its student a not 100% sure tho

The line of best fit is simply the trending line of a graph

Student A creates a better line of best fit

The linear equations are given as:

[tex]\mathbf{y = -2x + 24}[/tex]

[tex]\mathbf{y =1.5x + 23}[/tex]

The given graph shows a negative linear association.

This is so because, as the x-values increases, the y-values decreases.

This in other words means that:

The slope of the graph is negative

A linear graph is represented as:

[tex]\mathbf{y = mx + c}[/tex]

Where: m represents slope

By comparison

m = -2 and m = 1.5 for the equations of the two students.

Because the slope of the graph is negative, then

m =-2 is correct

Hence, student A creates a better line of best fit

Carlos can run 5 miles in 45 minutes, Kelly can run 10 miles in 80 minutes, and Mick can run 30 miles in 170 minutes

Answers

Answer:

Mick can run farther in less time if that's the question

Step-by-step explanation:

Mick's speed is faster.

What is speed?

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Carlos can run 5 miles in 45 minutes.

45 minutes = 45/60 = 0.75 hours

Speed.

= 5/0.75

= 6.66 miles per hour.

Kelly can run 10 miles in 80 minutes.

80 minutes = 1.33 hours

Speed.

= 10/1.33

= 7.5 miles per hour.

Mick can run 30 miles in 170 minutes

170 minutes = 2.8 hours

Speed.

= 30/2.8

= 10.7 miles per hour

The right answer is A

Step-by-step explanation:

The value of the exponential equation is y = 3ˣ and the graph is plotted

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the exponential equation be represented as A

Now , the value of A is

y = 3ˣ   be equation (1)

Now , the y intercept of the equation is when x = 0

So , when x = 0

y = 3⁰

y = 1

Now , when y₁ = 3^1.2

The value of y₁ = 3.7

Therefore , the y intercept of the equation is 1 and the graph is plotted

Hence , the exponential equation is y = 3ˣ

There exists a similarity transformation that maps AABC to AA'B'C'. The measure
of ZAis 68°, and the measure of ZBis 46°. What is the measure of ZC'in
degrees?

Answers

Answer:

∠C' = 66°

Step-by-step explanation:

Because triangles ABC and A'B'C' are similar, their angles are still the same; only their side lengths are different, though still proportionate.

Hence, ∠A = ∠A', ∠B = ∠B', and ∠C = ∠C'.

Here, we're given that ∠A = 68, which means ∠A' = 68; we also know that ∠B = 46, so ∠B' = 46.

We want to find C', so remember that all angles in a triangle sum to 180:

∠A' + ∠B' + ∠C' = 180

68 + 46 + ∠C' = 180

114 + ∠C' = 180

∠C' = 66°

Answer:

∠C' = 66°

Step-by-step explanation:

∠A' + ∠B' + ∠C' = 180

68 + 46 + ∠C' = 180

114 + ∠C' = 180

∠C' = 66°
