Simplify the following expression.

Answer:

  $293.75

Step-by-step explanation:

Any number of financial calculators, spreadsheets, and on-line calculators can compute the monthly payment for you. Or you can put the numbers into the formula and compute it yourself.

A formula I like is ...

  A = P(r/12)/(1 -(1 +r/12)^(-12t))

where A is the monthly payment, P is the loan amount, r is the annual interest rate, and t is the number of years. Filling in the given information and doing the arithmetic, we get ...

  A = $10000(0.18/12)/(1 -(1 +0.18/12)^(-12·4)) = $150/(1 -1.015^-48) = $293.75

Your monthly payment is $293.75.

x + 3y + 2x - 3x + 7 + 5

four,

3x + y - 12

4y + 3y + 3x - 6y - 10 - 2

Step-by-step explanation:

In order to match the equivalent expressions we have to put each expression in its simplest form

So,

[tex]x-3y+12\\\\12 - 3y - 2x + x + 2x\\=12-3y+x\\=x-3y+12\\\\3x + 2y - 2x + y + 12\\=x+3y+12\\\\4y + 3y + 3x - 6y - 10 - 2\\=3x+y-12\\\\x + 3y + 2x - 3x + 7 + 5\\=3y+12\\\\5 + 2y + 7x - 4x + 3y - 17\\=5y+3x-12[/tex]

One pair of equivalent expressions is:

x - 3y + 12

12 - 3y - 2x + x + 2x

Second,

x + 3y + 12

3x + 2y - 2x + y + 12

third,

3y + 12

x + 3y + 2x - 3x + 7 + 5

four,

3x + y - 12

4y + 3y + 3x - 6y - 10 - 2

..

Answer:

x + 3y + 12 <--> x + 3y + 2x - 3x + 7 + 5

x − 3y + 12 <--> 12 - 3y - 2x + x + 2x

3x + 2y − 2x + y + 12 <--> 3x + y - 12

3y + 12 <--> 4y + 3y + 3x - 6y - 10 - 2

Final answer:

The probability that Nick oversleeps and has a pop quiz on the same school day, given the probability of oversleeping at 48% and pop quiz at 25%, is 12%.

Explanation:

To find the probability that Nick oversleeps and has a pop quiz on the same day, we need to multiply the probabilities of the two independent events occurring.

The probability of Nick oversleeping is 48% or 0.48, and the probability of him having a pop quiz is 25% or 0.25. Since the events are independent, the combined probability is:

Probability(Nick oversleeps and has a pop quiz) = Probability(Nick oversleeps) × Probability(has a pop quiz) = 0.48 × 0.25

When you calculate this, you get:

0.48 × 0.25 = 0.12

Therefore, the probability that Nick oversleeps and has a pop quiz on the same school day is 12%.

The probability that Nick oversleeps and has a pop quiz on the same day is 12%.

To find the probability that Nick both oversleeps and has a pop quiz on the same day, we use the concept of independent events in probability. When two events are independent, the probability of both events occurring is the product of their individual probabilities.

Let's denote:
P(O) = Probability that Nick oversleeps = 0.48
P(Q) = Probability that there is a pop quiz = 0.25

The formula for finding the probability of both independent events occurring is:
P(O and Q) = P(O) * P(Q)

Therefore:
P(O and Q) = 0.48 * 0.25 = 0.12

So, the probability that Nick oversleeps and has a pop quiz on the same day is 12%.

Step-by-step explanation:

For this case we propose a system of equations:

x: Variable representing the plant with pink flowers

y: Variable representing the plant with purple flowers

We have as data that:

[tex]x + y = 15\\8x + 5y = 96[/tex]

From the first equation we have to:

[tex]x = 15-y[/tex]

Substituting in the second equation:

[tex]8 (15-y) + 5y = 96\\120-8y + 5y = 96\\-3y = 96-120\\-3y = -24\\y = \frac {-24} {- 3}\\y = 8[/tex]

Arianna bought 8 purple flowers.

Now we have:

[tex]x = 15-8\\x = 7[/tex]

Arianna bought 7 pink flowers.

Answer:

Arianna bought 7 pink flowers.

Using the Pythagoras Theorem, we can determine the value of c.

[tex] {c}^{2} = {( \sqrt{2} )}^{2} + {1}^{2} [/tex]

[tex] {c}^{2} = 2 + 1[/tex]

[tex]{c}^{2} = 3[/tex]

[tex]c = \sqrt{3} [/tex]

The ratio is the adjacent over the hypotenuse.

[tex]\cos B = \frac{1 }{ \sqrt{3} } [/tex]

We rationalize to get:

Answer:

The true statements are the third and fifth. [not sure about the second one!]

Step-by-step explanation:

1.) (7u + 4) is written as a sum of three terms.

This is false since 7u is one term, and 4  is one term, making a total of two terms, not three.

2.) 2 is a factor

I'm not sure on this but I don't think its true.

3.) In 7u, 7  is a coefficent

This is true. The coefficent is the number in front of a variable, or in this case, 7.

4.) In (7u + 4), 7u is a constant.

This is false, as a constant is a number without  any variable attached to it. The constant in this case would be 4.

5.) 8 and 1 are like terms.

This is true, since you can add 8 and 1, resulting in the sum of 9.

6.) None of these are true.

This is false, as at least 2 of these statements are true.

Hi my name is Kylie "How You Doing" phrase from Friends, Joey

Answer:

x = 1, y = 60

Step-by-step explanation:

Value of new-releases (x) = $20 each

Value of classic (y) = $8 each

Total budget = $500

Equation : 20x + 8y = 500

The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.

Lets assume the librarian buys at least one new-release DVD.

x=1

20x + 8y = 500

8y + 20(1) = 500

y = 60

Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.

Edge test math

Answer:

Ball Bearing Volume = (4 / 3) * PI * radius ^3

Volume = (4 / 3) * 3.14159265 * (.35)^3

Volume = (4 / 3) * 3.14159265 * 0.042875

Volume = 0.17959438 cc

1 cc of steel = 7.8 g

Volume of 1 kg of steel = 1,000 cc / 7.8 g per cc

1 kg = 128.205 cc

Number of ball bearings we can make = 128.205 / 0.17959438

y = -1/3x +3

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

   = (2-3)/(3-0)

   -1/3

Then we know the y intercept( where it crosses the y axis)

It crosses at y=3

The slope intercept form is

y= mx+b  where m is the slope and b is the y intercept

y = -1/3x +3

Answer:

[tex]y=\frac{-1}{3} x+3[/tex]

Step-by-step explanation:

Let frame the equation of the line using the points given on the graph

(0,3) and (3,2)

Equation of the line is y=mx+b

where m is the slope and b is the y intercept

To find slope we use formula

[tex]slope =\frac{y_2-y_1}{x_2-x_1} =\frac{2-3}{3-0} =\frac{-1}{3}[/tex]

Y intercept b is the point where the graph crosses y axis

y intercept b = 3

The equation y=mx+b becomes

[tex]y=\frac{-1}{3} x+3[/tex]

Answer:

Coach Johnson will save $1.50

Step-by-step explanation:

1. The first step is to calculate the unit price for each of the packages, ie. how much a single shin guard costs.

If we look at the package of 10 shin guards for $14.50, we can calculate the unit price by dividing the package price ($14.50) by the number of shin guards (10). Thus we get:

14.50/10 = $1.45

Now, if we do the same for the package of 15 shin guards for $22.50, we get:

22.50/15 = $1.50

2. Now we can see that the lowest unit price is $1.45 (package of 10 shin guards) and the highest unit price is $1.50 (package of 15 shin guards).

3. There are two ways to see how much he would save, so I will show both here.

1) First calculate how much the coach will have to pay for a pack of 30 shin guards for each of the packages:

3 packages of 10 shin guards for $14.50 = 3*14.5 = $43.50

2 packages of 15 shin guards for $22.50 = 2*22.5 = $45.00

Now subtract the second value from the first: 45-43.5 = 1.5

Therefor, he will save $1.50.

2) The second method is perhaps what I would personally use as it is a little quicker; so we already know that the unit price for the pack of 10 is $1.45 and the unit price for the pack of 15 is $1.50 - thus, we can say that there is a difference of $0.05 per shin guard in price. Now if we were going to calculate how much the coach would save in buying 30 shin guards, we could simply multiply how much he saves on a single shin guard by 30. Thus, we get:

0.05*30 = 1.5

Therefor, again we get the same answer that Coach Johnson would save $1.50.

Hope that helps :)

Nice problem.

The only way you can get an odd number by multiplying two digits together is if they are both odd.

For example 5*7 = 35 which is odd. You cannot find 2 odd numbers that when multiplied will give an even.

That means that A and B are both odd.

Now if you multiply an odd and an even together, you always get an even.

For example 4 * 9 = 36 which is even.

Since A is known to be odd, C must be even. So the four digit number you want ends in C.
