4/9

Answer:

Step-by-step explanation:

There are at least 2 ways you could do this. The best way is to use algebra. The trick is to equate 0.444444 to x, and then create a second equation by multiplying the first equation by 10. In doing this, you can subtract the two equations and that will get rid of the decimal.

10x = 4.444444...

  x =    .444444...             Now subtract these 2 equation

9x = 4                               Divide both sides by 9

9x/9 = 4/9

x = 4/9.

Since you are given choices, you could put each one into your calculator.

1/9 = 0,111111 not the answer.

40 /99 = 0.40404040 which is close but not the answer.

4 / 99 = 0.040404 ... which again is close but not the answer.

8 [tex]\frac{2}{3}[/tex] (8 2/3)

Question explanation:

5 [tex]\frac{3}{4}[/tex] +  2 [tex]\frac{11}{12}[/tex] = [tex]\frac{26}{3}[/tex] = 8 [tex]\frac{2}{3}[/tex]

(5 3/4) + (2 11/12) = (26/3) = (8 2/3)

(5 + 2) + ( [tex]\frac{3}{4}[/tex] + [tex]\frac{11}{12}[/tex] )

(5 + 2) + (3/4 + 11/12)

7 + 3 x 3 + [tex]\frac{11}{12}[/tex]

   (4 x 3)  (11/12)

7 + [tex]\frac{9}{12}[/tex] + [tex]\frac{11}{12}[/tex]

(9/12) + (11/12)

7 + 9 + 11

      (12)

7 + [tex]\frac{20}{12}[/tex]

(7 + 20/12)

7 + (20 ÷ 4)

     (12 ÷ 4)

7 + [tex]\frac{5}{3}[/tex]

(5/3)

7 + 1 [tex]\frac{2}{3}[/tex]  

( 1 2/3)

= 8 [tex]\frac{2}{3}[/tex]

 (8 2/3)

8 [tex]\frac{2}{3}[/tex] = [tex]\frac{26}{3}[/tex] = 8 [tex]\frac{2}{3}[/tex]

(8 2/3) (26/3) (8 2/3)

Answer:

First, set up equations for total cost for both Happy Paws and Woof Watchers.

x= number of hours

y= total cost

Happy Paws

y=3.50x +16

Woof Watchers

y=4.75x+11

4.75x+11=3.50x+16

x=4

You can check your answer by doing the following:

Happy Paws: (3.50)(4)+16= 30

Woof Watchers: (4.75)(4)+11= 30

Answer:

12

Step-by-step explanation:

if we know we want a profit of at least 114, we need to solve for x.

if we put 12 for x we get the answer 117 and when we put 11 for x we get less than 114.

-0.5(12)^2 + 25(12)-111 = 117

Answer:

all students in the club

Step-by-step explanation:

Answer:

C. All students in each grade

Step-by-step explanation:

Answer choices A and B are the worst choices to represent all students in the school. D can also be crossed off because students in the social studies club would most likely have a biased answer. Surveying all students in each grade produces the most random, unbiased results, so C would be the best answer.

Answer:

Step-by-step explanation:

Central tendency means “the statistical measure that identifies a single value as representative of an entire distribution." These measures include mean, median, and mode.

Andrew scores 79, 86, 63, and 82 on his tests.

63, 79, 82, 86

Mean: 79 + 86 + 63 + 82 = 77.5 or

Median: 79 + 82 = 80.5

(you have to add these numbers bc there is no exact median as none are repeating)

Mode: There is no exact mode since there is no repeating numbers.

He should use the mean bc the mean is a pretty good number.

I'm not sure if you would want to tell your mother that you're barely getting an average. or higher than failing.

either way, hope this helps :)

We're given:

Let a represent the number of children who swam.

Let b represent the number of adults who swam.

Because we've set two variables, we need two equations to be able to find the answers.

One of the equations will regard price while the other will regard the number of people, as those are the two things given in the question.

Number of people:

[tex]a+b=478[/tex]

Price:

[tex]1.75a+2.25b=975[/tex]

We can solve this question using substitution, where we plug one equation into the other.

Isolate a in the first equation:

[tex]a+b=478\\a=478-b[/tex]

Plug the first equation into the second equation by replacing a:

[tex]1.75a+2.25b=975\\1.75(478-b)+2.25b=975[/tex]

Solve for b:

[tex]1.75(478-b)+2.25b=975[/tex]

⇒ Open up the parentheses:

[tex]836.5-1.75b+2.25b=975\\836.5-0.5b=975[/tex]

⇒ Subtract 836.5 from both sides to isolate b:

[tex]-0.5b=138.5[/tex]

⇒ Divide both sides by -0.5:

[tex]b=277[/tex]

Solve for a:

[tex]a+b=478[/tex]

⇒ Replace b with 277:

[tex]a+277=478\\a=201[/tex]

There were 201 children and 277 children at the pool that day.

Answer: A and B.

Step-by-step explanation: The first option works because Clarissa is adding 64 fluid ounces of both orange and pineapple juice and 36 fluid ounces of apple juice which makes it an addition problem.  Option B works as well because it is similar to option A, only it shortens the problem by multiplying 64 twice, because 64 pops up twice.  Options C, D, and E don't work because it doesn't include taking away any juice or multiplying it in immense amounts, so that's why those are wrong.

Hope this helps! :)

175+(-16) is the same as 175-16, because you can carry the negative. 175-16=159, which is B.

Answer:

x = 13

Step-by-step explanation:

Using the 48° angle, we find out that the angle opposite of angle y° is also 48° according to the corresponding angles theorem. Then, you would subtract 48 from 180 to get the degrees of angle y, which would be 132°. Next, you need to subtract 132 from 180 to get the angle measure of the (5x - 17)° angle. (180 - 132 = 48) Once you have done that, all you have to do now is figure out what value of x makes it equal to the degree measure you found by subtracting 132 from 180. I tried it with x = 13, which came out as a correct answer. So x must be 13.

(5x - 17)°

(5(13) - 17)°

(65 - 17)°

(48)°

48°

The angle equals 48° and x equals 13.

Answer: 909.03

Step-by-step explanation:

We know that the equation is an exponential function, it can be written as y=ab^x

[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]

[tex]\Rightarrow ab^1=11[/tex]

[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]

[tex]\Rightarrow a=\frac{11}{b}[/tex]

a = 11/b, substitute it in equation 1

[tex]100 &=a b^{6.5}[/tex]

[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]

[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]

[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]

[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]

[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]

[tex]\Rightarrow {b} = 1.49379[/tex]

a = 11/b

a = 11/(1.49379)

a = 7.36382

Equation: y = (7.36382)(1.49379)^x

Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]

[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]

[tex]\Rightarrow 909.03[/tex]

Therefore, f(12) = 909.03 for the exponential function
