Answer:

the answer is $33.04

Step-by-step explanation:

since the total cost was $165.20 and we need to find the cost of one  video game we will divide the the total ($165.20) with 5 video games and you will get $33.04

Answer:

The first account, she invested = $4200 and in the second = $4800

Step-by-step explanation:

Let us assume that Genevieve invests $x at 6% ,

Hence, she invests ($9000 - $x ) at 4% ,

It's given that the combined interest from both of the above accounts is $444,

So,

0.06x + 0.04 (9000 - x) = 444

=> 0.06x + 360 - 0.04x = 444

=> (0.06x - 0.04x) + 360 = 444

=> 0.02x = 444 - 360

=> 0.02x = 84

=> x = 84/0.02

=> x = 8400/2 (By multiplying the denominator and numerator)

=> x = 4200

Therefore, 9000 - x = 9000 - 4200 = 4800

$4200 at 6% and $4800 at 4%

Therefore, the first account, she invested = $4200 and in the second = $4800

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

Step-by-step explanation:

Answer:

We are 95% confident that the true proportion of U.S. adults who live with one or more chronic conditions is between 39.7% and 46.33%

Step-by-step explanation:

From the question we are told that

  The  sample  proportion is [tex]\r p = 43\%  = 0.43[/tex]

   The  standard error is [tex]SE =  0.017[/tex]

Given that the confidence level is 95%  then the level of significance is mathematically represented as  

      [tex]\alpha =  (100-95)\%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as

     [tex]E = Z_{\frac{\alpha }{2} } *  SE[/tex]

=>    [tex]E = 1.96 *  0.017[/tex]

=>     [tex]E = 0.03332 [/tex]

Generally 95% confidence interval is mathematically represented as

      [tex]\r p -E <  p <  \r p +E[/tex]

=>   [tex]0.43 -0.03332 <  p <  0.43 + 0.03332[/tex]

=>    [tex] 0.39668 <  p <  0.46332[/tex]

Converting to percentage

[tex] (0.39668 * 100)<  p <  (0.46332*100)[/tex]        

[tex] 39.7\% <  p < 46.33 \%[/tex]    

Answer:

$4

Step-by-step explanation:

Divide $48 by 12

(Because there are 12 months in a year)

Your answer is $4

$48 divided along 12 months = $4

Hope I helped :)

Please consider Brainliest :)

Answer:

$4

To find the amount Rae pays each month, we have to divide 48 by 12 (because there are 12 months in a year.)

48 ÷ 12 = 4.

Answer = $4.

Quantity of water with Henri = 16 litres

Quantify of water he will need for one cup of coffee = 200 ml

Number of cups of coffee he can make with a full cup of water :-

[tex] = 16 \: litres \: = 16000 \: ml[/tex]

[tex] = \frac{16000}{200} [/tex]

[tex] = 80 \: cups \: of \: coffee[/tex]

So , Henri can make 80 cups of coffee with one full bottle of water .

Quantity of water needed to make 80 cups of coffee = 16,000 ml

Quantity of water needed to make one cup of coffee :-

[tex] = \frac{16000}{80} [/tex]

[tex] = 200 \: ml[/tex]

So , 200 ml of water is needed to make one cup coffee .

Quantity of water he needs to make 250 cups of coffee :-

[tex] = 200 \times 250[/tex]

[tex] = 50000 \: ml[/tex]

So , Henri needs 50,000 ml of water to make 250 cups of coffee .

Number of water containers he will use :-

[tex] = \frac{50000}{16000} [/tex]

[tex] = 3.125 \\ = 3 \: water \: containers[/tex]

So , Henri will use 3 full water containers to make 250 cups of coffee .

Money charged per one coffee = 8 cents

Money charged for 250 coffees :-

[tex] = 250 \times 8[/tex]

[tex] = 2000 \: cents[/tex]

So , Henri will make 2000 cents if he sells 250 cups of coffee .

Therefore , Henri will use 3 full containers of water to make 250 cups of coffee and he he will make 2000 cents by selling 250 cups of coffee .

Answer:

C 60

Step-by-step explanation:

This is because if you do 303+60=363 and then you do 363/11 you get 33. So x=60

60

Multiply both sides of the equation by 11:

303 + x =363

Move constant to the right side and change its sign:

x = 363 - 303

Then,subtract the numbers:

x = 60

Answer:

Step-by-step explanation:

When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:

  2(x +3) = 30 . . . . an equation for the given conditions

__

We can solve this equation by dividing by 2:

  x + 3 = 15

  x = 12 . . . . . . subtract 3

The number is 12.
