Andrew paid for his burger with a 20% off coupon. If he paid $10 for his burger, what was the original price?

Answer:

Option 2 4y + y = 45

Step-by-step explanation:

Answer:

B. 61

Step-by-step explanation:

Given that ∆PQR and PQS are congruent, it follows that their corresponding sides are of the same length.

Therefore,

[tex] RQ = SQ [/tex]

[tex] 3x + 16 = 7x - 24 [/tex]

Collect like terms

[tex] 16 + 24 = 7x - 3x [/tex]

[tex] 40 = 4x [/tex]

Divide both sides by 4

[tex] \frac{40}{4} = \frac{4x}{4} [/tex]

[tex] 10 = x [/tex]

[tex] x = 10 [/tex]

Find PQ:

[tex] PQ = 2x + 41 [/tex]

substitute x = 10 into the equation

[tex] PQ = 2(10) + 41 [/tex]

[tex] PQ = 20 + 41 [/tex]

[tex] PQ = 61 [/tex]

Answer:

Hi there!

Your answer is:

The length is 17

Step-by-step explanation:

L= 11+w

P=46

perimeter formula:

W+W+L+L = P

W+W+(11+w)+(11+w) = P

First solve for W

4W+22 = 46

-22

4w=24

/4

w=6

Now plug in W for the L formula

l=11+w

L= 11+ 6

L=17

Answer:

$14.07

Step-by-step explanation:

100-15=85

You change this into a multiplier 0.85.

18x0.85=15.30

100-8=0.92

0.92x15.30=14.07

Answer:

The probability the earth is saved is [tex]P(X >  3) = 0.8753 [/tex]

Step-by-step explanation:

From the question we are told that  

   The number of missiles lunched by earth is n =  500

   The probability that each missile will hit the rocket is  p(x) =  0.01

Generally the expected number of  missiles that will hit the rocket is  

    [tex] \lambda =  n  *  p(x)[/tex]

    [tex]\lambda =  500  *  0.01 [/tex]

    [tex]\lambda =  5[/tex]

Gnerally the probability that Earth will be saved is mathematically represented as

      [tex]P(X >  3) =  1 - P(X \le 2)[/tex]

=>    [tex]P(X >  3) =  1 -  P( X = 0 ) + P(X =1 ) + P( X = 2) [/tex]

Gnerally the probability distribution function of a Poisson distribution is

      [tex]P(K) =  \frac{e^{- \lambda t } *  (\lambda *  t)^k}{k!}[/tex]

Here t =  1

Hence

      [tex]P( X = 0 ) =  \frac{e^{-5} *  5^0 }{0!}[/tex]

      [tex]P(X =1 ) =\frac{e^{-5} *  5^1 }{1!}[/tex]

     [tex]P( X = 2) = \frac{e^{-5} *  5^2 }{2!}[/tex]

 [tex]P(X >  3) =  1 - [ \frac{e^{-5} *  5^0 }{0!} + \frac{e^{-5} *  5^1 }{1!} +  \frac{e^{-5} *  5^2 }{2!}][/tex]

[tex]P(X >  3)= 1 - [ \frac{0.00673 }{1} + \frac{0.033689}{1} +  \frac{0.168449 }{2}][/tex]

[tex]P(X >  3) = 0.8753 [/tex]

Answer:

18 Nickels, 6 Quarters

Step-by-step explanation:

For this problem, let's build a system of equations to find the number of nickels and dimes you have.  Let N represent the number of nickels and Q represent the number of quarters you have.

The first equation, you have 3 times as many nickels as quarters:

N = 3Q

The second equation, you have a total of $2.40.  Given we know nickels are $0.05 and quarters are $0.25:

0.05N + 0.25Q = 2.40

Now, let's use the two equations to find the number nickels and quarters you have.

N = 3Q

0.05N + 0.25Q = 2.40

0.05(3Q) + 0.25Q = 2.40

0.15Q + 0.25Q = 2.40

0.4Q = 2.40

Q = 6

Now, let's plug the value back into the equation:

N = 3Q

N = 3(6)

N = 18

And we can verify these values with the second equation:

0.05N + 0.25Q = 2.40

0.05(18) + 0.25(6) ?= 2.40

0.90 + 1.50 ?= 2.40

2.40 == 2.40

Therefore, we have found and verified the amount of Nickels and Quarters you have.

Cheers.

Answer:

1.46 X [tex]10^{8}[/tex]

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Let the smallest number be n.

If the next integer differs by 3 then:

n + 3 is our second integer.

If the product is 108 then we would multiply them together.

n * (n + 3) = 108    Now solve for n.

(n*n) + (n*3) = 108

[tex]n^{2} +3n = 108[/tex]     Now we move 108 to the other side by subtracting so we can factor.

[tex]n^{2} + 3n - 108 = 0[/tex]

(n       )(n       ) = 0    

Find all the multiples of 108

1 x 108

2 x 54

3 x 36

4 x 27

6 x 18

9 x 12

Which one can we add or subtract together to get 3?

9 x 12    because 12 - 9 = 3

[tex]n^{2} + 3n - 108 = 0[/tex]

(n    12)(n     9) = 0    Now we figure out the signs. Since we have -108 one must be negative, and the 3 in the 2nd term (3n) is positive so:

(n + 12)(n - 9) = 0   Is our factored equation.

Our smallest number is 9, so n = 9

Our second number is n + 3 and 9 + 3 = 12

So our 2 integers are 9, 12, there sum would be 9 + 12 = 21

Option A.

Answer:

200.88

Step-by-step explanation:

324 · 0.62 = 200.88

(0.62 is equal to 62%)

Hope I helped :)

Please consider Brainliest :)

62% of 324 is 200 Round to the nearest hundredth.

In mathematics,a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now the given number is 324.

Given percentage is 62% or 0.62.

So for 62% of 324 we have,

62% of 324 = 0.62 x 324

or, 62% of 324 = 200.88

Now to round to the nearest hundredth we have

200.88 ≈ 200 round to the nearest hundredth.

Hence,  62% of 324 is 200 Round to the nearest hundredth

which type of equation just tell we are here to help if we can

Answer:  Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.

If the word "is" or "are" is included in the description, that is equivalent to an equal sign.

Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.  

"From" and "difference" are clues that there is subtraction.

"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.

"Ratio," 'into' "per" and "among" are clues to division.
