Pete is purchasing a smart phone for $249.30 he gives the sales clerks 3 fifty-dollar bills 4 twenty-dollar bills, and 4 five-dollar bills. how much should he receive in change

Answer: y=4x-2

Step-by-step explanation:

Slope-intercept form: y=ax+b, where a is the slope and b is the y-intercept.

Given: slope is 4, and y-intercept is -3

y=ax+b

y=4x+(-3)

y=4x-3

Hope this helps!! :)

Answer:

4a²(a² - 5)​

Step-by-step explanation:

4a⁴ – 20a² =

4a²× a² - 4a²×5 =              ⇒ common factor is 4a²

4a²(a² - 5)​                         ⇒ factorized

Answer:

Just multiply with 1000

You get 2961

So 2961

=================================================

Explanation:

r = correlation coefficient

If r is close to -1, then the points are close to (or some fall on) the same straight line that has a negative slope. We consider this be a strong negative linear correlation.

If r is close to +1 or just 1, then the points are close to the same straight line that has a positive slope. These points would be considered to have strong positive linear correlation.

By "same straight line", I mean the regression line or line of best fit.

Answer:

Step-by-step explanation:

So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.

Answer:

12

Step-by-step explanation:

max cap 670lb- delivery person 160lb  weight left 510lb

weight 510lb/each box 40lb number of boxes 12.75lb

each box 40lb times number of boxes 12lb  480lb+160lb 640lb

so your still have 30 lb before max weight of elevator

Answer: X= 2.5

Step-by-step explanation:

Answer:

0.29 rounded to the nearest ones is 0.

0.29 rounded to the nearest tenths is 0.3

0.29 rounded to the nearest hundredths is 0.29

Step-by-step explanation:

Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.

Round to the nearest ones:

Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:

0.29 rounded to the nearest ones is 0.

Round to the nearest tenths:

Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:

0.29 rounded to the nearest tenths is 0.3

Round to the nearest hundredths:

Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).

0.29 rounded to the nearest hundredths is 0.29

Number of pieces:

Answer:

EA, EB, EC and ED are opposites rays.

Step-by-step explanation:

Given that,

Line AB and line CD intersect at point E.

According to figure,

We need to find opposite rays

Using diagram

We draw a first line AB and second line CD which is intersect of AB at point E.

Now, EA and EB is called opposite ray of first line AB.

Similarly,

EC and ED is called opposite ray of first line CD.

Hence, EA, EB, EC and ED are opposites rays.

Answer:

07:43: 12 AM

Step-by-step explanation:

Given that:

Traffic lights change after every 48, 72 and 108 seconds.

They changed simultaneously at 7:00 AM.

To find:

At what time, they will change simultaneously again ?

Solution:

For this, we need to find LCM(Least Common Multiple) of the three numbers and then add it to 7:00 AM to find the time they will change together again.

Because LCM of 3 numbers is the least number which is divisible by all 3 numbers.

Let us factorize the numbers and underline the common part:

[tex]48 = \underline{12}\times 4\\72 = \underline{12}\times 6\\108 = \underline{12}\times 9[/tex]

Common part is taken only once and the remaining part is multiplied to it to find the LCM.

So, LCM = [tex]12 \times 4\times 6 \times 9 = 2592[/tex]

In 2592 seconds, they will change together again.

Changing 2592 seconds in minutes:

Let us divide it by 60:

We get 43 minutes 12 seconds.

Let us add it to 7:00AM, we get the following:

So, the time at which they will change simultaneously = 07:43: 12 AM

Answer:

Number of ways = 6

Step-by-step explanation:

Given:

Total number of choices = 4

Taken object choices = 2

Find:

Number of ways

Computation:

Number of ways =  [4 × 3] / 2!

Number of ways = [4 × 3] / [2 × 1]

Number of ways = [12] / [2]

Number of ways = 6

Answer:

These are the awnsers to it!

Step-by-step explanation:

Answer:

A=7

Step-by-step explanation:

2a-6a+24=-4

simplify

-4a+24=-4

subtract 24 from both sides

-4a=-28

divide both sides by -4

a = 28/4

simplify 28/4 to 7

a=7

Answer:

[tex]\frac{5}{18}[/tex]

Step-by-step explanation:

When dividing fractions, the formula is simple: Keep Flip Change (KFC)

So keep [tex]\frac{1}{4}[/tex] change your division sign to a multiplication sign, and flip [tex]\frac{9}{10}[/tex] so it becomes [tex]\frac{10}{9}[/tex].

[tex]\frac{1}{4}[/tex]·[tex]\frac{10}{9}[/tex]=[tex]\frac{10}{36}[/tex]

Then you need to reduce your fraction to simplest form.

[tex]\frac{5}{18}[/tex]

Answer:

1.) Yes

2.) Yes

Step-by-step explanation:

Given that

n = k(k + 7)

If k is a positive integer and n = k(k + 7), is n divisible by 6 ?

(1) k is odd. Yes.

Let assume that k = 3

Then, n = 3(3 + 7)

n = 3 × 10

n = 30.

30 is divisible by 6.

(2) When k is divided by 3, the remainder is 2. That is,

Let k = 5

Then,

5/3 = 1 remainder 2

Substitute k into the equation

n = k(k + 7)

n = 5(5 + 7)

n = 5 × 12

n = 60

And 60 is divisible by 6.

Therefore, the answer to both questions is Yes.

Answer:

x = ± [tex]\frac{6}{11}[/tex]

Step-by-step explanation:

Given

x² = [tex]\frac{36}{121}[/tex] ( take the square root of both sides )

x = ± [tex]\sqrt{\frac{36}{121} }[/tex] = ± [tex]\frac{\sqrt{36} }{\sqrt{121} }[/tex] = ± [tex]\frac{6}{11}[/tex]

Answer:

Yes

Answer:

25.08

Step-by-step explanation:

-12n - 2 = -303

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, n. Do the opposite of PEMDAS.

First, add 2 to both sides:

-12n - 2 (+2) = -303 (+2)

-12n = -303 + 2

-12n = -301

Next, divide -12 from both sides:

(-12n)/-12 = (-301)/-12

n = -301/-12 = 301/12

n = 25.08 (rounded).

Answer:
