Answer:

90%

Step-by-step explanation:

Answer:

90%

Step-by-step explanation:

To determine what percentage of money she spent, you would divide the amount she spent by the total amount she had.  

$45 ÷ $50 = 0.9

You would then multiply the decimal times 100 to convert the decimal to a percentage.

0.9 · 100 = 90

Answer:

y - 6 = (5/6)(x - 4)

Step-by-step explanation:

Write an equation that represents the line through the points (-2,1) and (4,6)

As we move from (-2, 1) to (4, 6), x increases by 6 and y increases by 5.

Thus, the slope of the line connecting these two points is m = rise/run = 5/6.

Using (4, 6) as one point on the line, the equation of the line in point-slope form is

y - 6 = (5/6)(x - 4)

Answer: y - 6 = (5/6)(x - 4

Answer:

84 students

Step-by-step explanation:

Let x be the number of adults.

Then the number of children is 2x, according to the condition,

and the number of students is the rest (315-x-2x) = (315-3x).

The "money" equation (the revenue equation) is

   12x + 5x(2x) + 7x(315-3x) = 2282.

   12x + 10x + 7x315 - 21x = 2282

   x = 2282 - 7x315 = 77  is the number of adults.

 77 adults :2 x 77 = 154 children and the rest (315-77-154) = 84 students.

Answer:

15 years ago

Step-by-step explanation:

So it was when Sam was x=3 years old and Bill was 3x=9 years old that Bill was 3 times as old as Sam. And since their ages are now 18 and 24, that was 15 years ago.

Answer:

The answer is 15 years

Step-by-step explanation:

The domain of the function y = 2√(x - 6) is all real numbers x such that x is greater than or equal to 6. This is represented as [6, ∞).

The domain of the function y = 2√(x - 6) is the set of all x-values for which the expression inside the square root is non-negative. This is because the square root function is only defined for non-negative values.

To find the domain, we set up the inequality:

x - 6 ≥ 0

Solving this inequality, we get

x ≥ 6

Therefore, the domain of the function y = 2√(x - 6) is [6, ∞). This includes all real numbers x starting from 6 to positive infinity.

Answer:

1/4 < 5/4

Step-by-step explanation:

Since the numbers have the same denominator, we compare the numerators

1 < 5

so 1/4 < 5/4

Answer:

5/4

Step-by-step explanation:

Hello there!

Since each number is given in terms of 4ths, we can look at which has more 1/4 that comprises it.

5>1, so 5/4 is greater.

Answer:

it is 1/5

Step-by-step explanation:

the factor of the coordinates b(10,-15) and b'(2,-3) is five, but the figure gets smaller and is a reduction. therefore the scale factor is between 0-1, making it 1/5.

Answer:

the area is 146 mi^2 and the perimeter is 54

Step-by-step explanation:

Answer

perimeter = 44 mi

area = 146 mi²

Step by step

perimeter = 9 mi + 10 mi + 2 mi + 8 mi + 7 mi + 18 mi

perimeter = 44 mi

area = (2 × 10) + (7 × 18)

area = 20 + 126

area = 146 mi²

Answer:

Given:

Sample size, n = 640

Since result showed that 99.2​% of them would erase all of their personal information online if they could, we have:

P' = 99.2% = 0.992

Let's take p = 50%

Our null and alternative hypothesis will be :

H0 : u = 0.5

H1 : u > 0.5

In this case we are to check for the test statistic.

[tex] \frac{P' - p}{\sqrt{p(1-p)/n}} [/tex]

[tex] = \frac{0.992 - 50}{\sqrt{50(1-50)/640}} [/tex]

= 24.9

Test statistic, Z = 24.893

In conclusion, the results are significantly high, which suggets there is suffcient evidence to support the claim that most adults would erase all of their personal information online.

Answer:

Probability (sum of the numbers ≥ 10) = 1/6

Step-by-step explanation:

Given:

Number of Dice = 2

Total number on dice = 1, 2, 3, 4, 5, 6

Find:

Probability (sum of the numbers ≥ 10)

Computation:

Total number of probability = 6 × 6

Total number of probability = 36

Sum of number greater than or equal to 10 are:

(4,6), (5,5), (5,6), (6,6), (6,4), (6,5)

Total number of outcomes = 6

Probability (sum of the numbers ≥ 10) = Total number of outcomes / Total number of probability

Probability (sum of the numbers ≥ 10) = 6 / 36

Probability (sum of the numbers ≥ 10) = 1/6

Answer:

n = 20

Step-by-step explanation:

Add 7n to both sides.

-5n + 7n - 12 = 2n - 12.

-7n + 7n + 28 = 28.

Now the equation is 2n - 12 = 28.

Add 12 to both sides to isolate the variable.

2n - 12 + 12 = 2n.

28 + 12 = 40.

Now the equation is 2n = 40. Divide both sides by 2.

n = 20.

Answer:

n=20

Step-by-step explanation:

-5n-12 =-7n+28

plus 7n to each side

2n - 12 = 28

add 12 to each side

2n=40

divde by 2 to isolate the n.

you get n=20

Answer:

225 adult tickets were sold

To determine the number of adult tickets sold for the school play, we set up an equation with the variable representing adult tickets, and considered that there were 53 more student tickets sold than adult tickets. Solving the equation given the total number of tickets (503), we found that 225 adult tickets were sold.

The question is asking us to find out how many adult tickets were sold for the school play when given the total number of tickets and the information that there were 53 more student tickets sold than adult tickets. To do this, we'll let the number of adult tickets be represented by x and the number of student tickets be x + 53, as there were 53 more student tickets than adult tickets.

The total number of tickets sold is 503, which is the sum of adult tickets and student tickets. So, x (adult tickets) + (x + 53) (student tickets) = 503. Combining like terms, we get 2x + 53 = 503. Subtracting 53 from both sides, we have 2x = 450. Dividing both sides by 2 gives us x = 225. Therefore, 225 adult tickets were sold.

Answer:

1/2 gallon

Step-by-step explanation:

Each full gallon can be represented as 4/4 of a gallon. Since Katie bought 2 one-gallon bottles, the total amount of juice is 8/4 gallons. The number line below represents the fraction of juice that her guests drank.

[tex]\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\\ \frac{1}{4}\ \ \frac{2}{4}\ \ \frac{3}{4}\ \ \frac{4}{4}\ \ \frac{5}{4}\ \ \frac{6}{4}\ \ \frac{7}{4}\ \ \frac{8}{4}[/tex]

The fraction of a gallon of juice left over is:

[tex]f=\frac{8}{4}-\frac{6}{4} =\frac{2}{4}\\f=\frac{1}{2}[/tex]

Therefore, there is 1/2 of gallon of juice left over.
