Answer:  115 Adults and 120 Children

Step-by-step explanation:

We have 2 unknowns:  A is the number of Adults and C is the number of children.

We'll need at least two equations to solve for two unknowns.

One equation is easy:  We know that A + C = 235, the total number of people who entered the park.

The second equation comes from the second fact that was provided:  total admission fees were $640.  We can write the sum of the two unknowns, A and C, when multiplied by their respective admission fee:

4A + 1.5C = $640  [$4 * the number of adults plus $1.5 * the number of children]

Rearrange the first equation for either variable, A or C.  I picked A:

A = 235 - C

Now use this value for A in the second equation:

4A + 1.5C = $640

4*(235-C) + 1.5C = $640

-2.5C + 940 = 640

-2.5C = -300

C = 120 children

To find A:

A = 235 - C

A = 235 - 120

A = 115 adults

===

Double check to see if these value work:

                    C       A

Fee($)          1.5      4

People        120    115

Income ($)   180   460

Total = 180 + 460 = $640

It works.  120 Adults and 115 Children.

Step-by-step explanation:

the answer is the factor of n : 70.

with every sold ticket the charity raises $70.

add on :

to break even (to have at least 0 or more dollars as profit) they need to sell at least

70n - 1500 = 0

70n = 1500

7n = 150

n = 150/7 = 21.42857143...

that means, since they can't sell parts of tickets, they need to sell at least 22 tickets.

Answer:

I think the answer would be +15.

Step-by-step explanation:

The change in points in the most recent round as an integer is given by 15 points.

Given is Nguyen played a game in which he could either lose or gain points each round. at the end of 7 rounds, he had -8 points. After one more round, he had 7 points.

Assume that the change in points in the most recent round as an integer is given by [ΔR].

At -

R{7} = - 8 points

R{8} = 7 points

ΔR = R{8} - R{7}

ΔR = 7 - (- 8)

ΔR  = 7 + 8

ΔR  = 15 points

Therefore, the change in points in the most recent round as an integer is given by 15 points.

The answer is 4+5+6=15.Hope that helps. :)

Answer:

Step-by-step explanation:

Let the first number be x,

The second number (since it is consecutive) will be = x + 1

The third number (since it is right after the second) = (x+1) + 1 = x + 2

x + x + 1 + x + 2 = 15

3x + 3 = 15

3x = 15 - 3

3x = 12

x = 12/3 = 4

If the first number = 4,

Second number will be = 5 [(x+1) = 4+1]

Third number will be = 6 [(x+2) = 4 + 2]

381.(3) [km.]

Step-by-step explanation:

if according to the condition distance=286 [km] per 3 hours, then it is possible to make up the equation:

[tex]\frac{286}{3}=\frac{d}{4};[/tex]

and to calculate required distance 'd':

[tex]d=\frac{286*4}{3}=381.(3)[km].[/tex]

The alteration has an effect on (K) I, II and III

The function is given as:

[tex]h = -at^2 + bt + c[/tex]

When the constant term (c) is altered, i.e. changed, the function becomes a different function entirely.

Take for instance, the new function is:

[tex]h = -at^2 + bt + c+ 1[/tex]

The functions [tex]h = -at^2 + bt + c[/tex] and [tex]h = -at^2 + bt + c+ 1[/tex] are different, and both functions will have different intercepts and vertices.

Hence, the alteration has an effect on (K) I, II and III

Answer: 40%

Step-by-step explanation:

To find the percent, divide the amount donated by the full amount of money raised. 400/1000 = 0.4.

Now to make this into a percentage, multiply the answer by 100. 0.4 * 100 = 40.

Percent of the fund raiser did they donate to charity 40%

In mathematics, a percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100. It is represented by the symbol “%”.

Percentages have no dimension. Hence it is called a dimensionless number. If we say, 50% of a number, then it means 50 per cent of its whole.

To find the percent,

divide the amount donated by the full amount of money raised. 400/1000 = 0.4.

Now to make this into a percentage,

multiply the answer by 100.  0.4 * 100 = 40.

Step-by-step explanation:

The exponential growth rate formula is as follows:

F = A(1+r)^t, with F representing the final amount, a representing the initial amount, r representing rate, and t representing time. Here, we have

A = 100, r = 50% = 0.5 (divide 50% by 100 to convert it to a decimal), and t = 6. Plugging these in, we get

F = 100(1+0.5)^6 = 1139
