distributive property of the product of 127 and 32

Answers

Answer 1

127(32) could be re-written as (130-3)(30+2). To evaluate this, we'd use the distributive property of multiplication: 130(30) + 130(2) - 3(30) -3(2).

That comes out to 3900 + 260 - 90 - 6. Combine the positive terms. Then combine the negative terms. Last, combine the single positive term with the single negative one: 4160 - 96 = ?

A bank offers a money market account paying 4.9% interest compounded semiannually. A competing bank offers a money market account paying 4.8% interest compounded daily. Which account is the better investment?

Answers

Assume $1000 at 4.9% semi-annually = $1,049.60
Assume $1000 at 4.8% daily = $1,049.17

Let's try a bigger number $50'000 4.9% semi-annually $52,480.01
$50,000 4.8% daily = $52,458.37
It's a wash, the question is how long will you be investing, that might make a difference. I calculated 12 Millions over 6 years and bank A would be the better choice. Semi-annual compounded at 4.9%

Mary having her living room and bedroom painted. Interior Designs USA charges $60.00 to evaluate the space plus $35.00 per hour of labor. Splash of Color charges $55.00 per hour with no initial fee. Which of the following are true? Select all that apply.

If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least.

Splash of Color will always charge the least.

If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.

If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA.

If it takes 3 hours to paint the rooms, both companies will charge the same amount.

Answers

Answer:

The correct statements are 1, 3, and 5.

Explanation:

Let's calculate the total cost for each company based on the given information:

For Interior Designs USA:

- Evaluation fee: $60.00

- Labor cost per hour: $35.00

- Total labor cost for 7 hours: $35.00/hour × 7 hours = $245.00

- Total cost = Evaluation fee + Total labor cost = $60.00 + $245.00 = $305.00

For Splash of Color:

- Labor cost per hour: $55.00

- Total labor cost for 7 hours: $55.00/hour × 7 hours = $385.00

Now, let's analyze the statements:

1. If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least. - True. ($305.00 < $385.00)

2. Splash of Color will always charge the least. - False. In this case, Interior Designs USA charges less for 7 hours of work.

3. If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective. - True. As we've seen, Splash of Color charges $55.00 per hour, while Interior Designs USA charges $35.00 per hour plus an initial fee.

4. If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA. - False. Let's calculate:

- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 10 hours = $60.00 + $350.00 = $410.00

- Splash of Color: $55.00/hour × 10 hours = $550.00

Splash of Color charges $550.00 - $410.00 = $140.00 more, not $200. Therefore, this statement is false.

5. If it takes 3 hours to paint the rooms, both companies will charge the same amount. - False. Let's calculate:

- Interior Designs USA: $60.00 (evaluation fee) + $35.00/hour × 3 hours = $60.00 + $105.00 = $165.00

- Splash of Color: $55.00/hour × 3 hours = $165.00

They both charge $165.00, so this statement is true.

So, the correct statements are 1, 3, and 5.

Solve P=2D+2C for D

Answers

P-2c/2 = D So, P-2c all over 2 is equal to D.

Answer: D = (P - 2C)/2

Step-by-step explanation:

We want to solve P= 2D + 2C for D

This means "isolate D in one side of the equation"

The first step is subtracting 2C in the both sides of the equation:

P - 2C = 2D + 2C - 2C = 2D

P - 2C = 2D

Now, we want to take of the multiplication that is acting on D, so we divide in both sides by 2:

(P - 2C)/2 = (2D)/2 = D

Now we have D isolated, and this is:

D = (P - 2C)/2

an air traffic controller is tracking two planes. To start, playing a is at an altitude of 2814 ft and plan B is just taking off. Plan a is gaining altitude at 30.5 feet per second in playing day is gaining altitude at 80.75 feet per second. How many seconds will pass before the planes are on the same altitude

Answers

Model the altitude of each plane with a linear equation.
The initial altitude is the 'y-intercept'.
The rate of elevation is the slope.

Plane A: y = 30.5x + 2814

Plane B: y = 80.75x

The planes will be at same altitude when the y values are equal.
80.75x = 30.5x + 2814

Solve equation for 'x'.
80.75x - 30.5x = 2814
50.25x = 2814
x = (2814/50.25) = 56

Answer:
It will take 56 seconds before planes are at same altitude.

Answer:

56 seconds will pass.

Which equation has the same solution as 4-2(x-5)-x-19

Answers

i believe the equation with the same solution is -3x-5

The equation 3x - 4 = 2x + 7 has the same solution as 4 - 2(x - 5) = x - 19, with both solutions yielding x = 11.

Let's solve the equation step-by-step: 4 - 2(x - 5) = x - 19

First, expand the left side:
4 - 2x + 10 = x - 19Combine like terms:
14 - 2x = x - 19Move all terms involving x to one side:
14 = 3x - 19Move constant terms to the other side:
33 = 3xSolve for x:
x = 11

Now, let's compare this solution to other given equations:

2(x + 5) = -8
2x + 10 = -8
2x = -18
x = -9 (Not a match)3(x - 3) = 9
3x - 9 = 9
3x = 18
x = 6 (Not a match)x + 2 = 2x - 3
2 = x - 3
x = 5 (Not a match)3x - 4 = 2x + 7
3x - 2x = 7 + 4
x = 11 (Match)

The equation with the same solution as 4 - 2(x - 5) = x - 19 is 3x - 4 = 2x + 7.

Complete question: Which equation has the same solution as 4 - 2(x - 5) = x - 19?

2(x + 5) = -83(x - 3) = 9x + 2 = 2x - 33x - 4 = 2x + 7

What is the probability that the selected consumer is 35–55 years old or likes crunchicles?

Answers

Final answer:

The probability that a selected consumer is 35–55 years old or likes crunchicles is 0.5.

Explanation:

To determine the probability that the selected consumer is 35–55 years old or likes crunchicles, we need to add the probabilities of these two events happening individually and subtract the probability of both events happening. Let's assume the probability of a randomly selected consumer being 35–55 years old is 0.4 and the probability of a randomly selected consumer liking crunchicles is 0.3. The probability of a randomly selected consumer being both 35–55 years old and liking crunchicles is 0.2. Therefore, the probability that the selected consumer is 35–55 years old or likes crunchicles is:

P(35-55 or crunchicles) = P(35-55) + P(crunchicles) - P(35-55 and crunchicles)

= 0.4 + 0.3 - 0.2 = 0.5

Raffle tickets are being sold for a fundraiser. The function a(n) relates the amount of money raised to the number of tickets sold, n.

It takes as input the number of tickets sold and returns as output the amount of money raised.

a(n) = 3n – 15

Which equation represents the inverse function n(a), which takes the money raised as input and returns the number of tickets sold as output?

Answers

Answer:

For apex it is N(a)= [tex]\frac{a+15}{3}[/tex]

Final answer:

To find the inverse function, solve the equation a = 3n - 15 for n. The inverse function is n(a) = (a + 15) / 3.

Explanation:

To find the inverse function, we need to solve the equation n(a) = 3n - 15 for n.

Step 1: Replace n(a) with a: a = 3n - 15

Step 2: Solve for n.

Add 15 to both sides of the equation.a + 15 = 3nDivide both sides of the equation by 3.(a + 15) / 3 = n

Therefore, the inverse function is n(a) = (a + 15) / 3.

Find the roc of the volume of a cube with respect to the length of its side s

Answers

If the length of one side of a cube is s, then the derivative of the formula for the volume of the cube is

dV/ds = 3s^2.

The roc of the volume of a cube with respect to the length of its side s is 3s².

What is rate of change?

The rate of change of a function is the rate at which the output values change over the input value.

The rate of change of a function is one degree less than the actual function.

The volume of a cube is :

V = s³

The rate of change of volume V with respect to length a will be :

dV/ds = d(s³ )/ds

= 3s²

This means that, a cubic function will have a quadratic rate of change

Hence, The roc of the volume of a cube with respect to the length of its side s is 3s².
