Answer:

2 kilos  and costing  $22

Step-by-step explanation:

45 adult tickets and 80 children tickets were sold

Solution:

Let "a" be the number of adult tickets sold

Let "c" be the number of children tickets sold

Cost of 1 adult ticket = $ 6

Cost of 1 children ticket = $ 3.50

They sold a total of 125 tickets

Therefore,

a + c = 125

c = 125 - a --------- eqn 1

They made a total of $550. Therefore, frame a equation as:

number of adult tickets sold x Cost of 1 adult ticket + number of children tickets sold x Cost of 1 children ticket = 550

[tex]a \times 6 + c \times 3.50 = 550\\[/tex]

6a + 3.50c = 550 ----------- eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 1 in eqn 2

6a + 3.50(125 - a) = 550

6a + 437.5 - 3.50a = 550

2.5a = 112.5

Substitute a = 45 in eqn 1

c = 125 - 45

Thus 45 adult tickets and 80 children tickets were sold

Answer:

y = -2x + 13

Step-by-step explanation:

for equation of a line

(x - x1)/(x2 - x1) = (y - y1)/(y2 - y1)

(x - 5)/(4 - 5) = (y - 3)/(5 - 3)

cross multiplying

2(x - 5) = -1(y - 3)

2x - 10 = -y + 3

y = -2x + 13

The answer to this problem is simple 134

Answer:

No solution

Step-by-step explanation:

We need to isolate x.

Start by performing the indicated multiplication:

3x - 1.5 = 3 + 3x

This has no solution, since 3x = 3x for any x value and -1.5 never equals 3.

Answer:

The third side is

B. [tex]2x[/tex]

Step-by-step explanation:

Given:

Perimeter of triangle = [tex]10x+12y[/tex]

Two sides of the triangle are :

1) [tex]4x+14y[/tex]

2) [tex]4x-2y[/tex]

To find the third side.

Solution:

Let the third side be = [tex]z[/tex]

The perimeter can be given as sum of all 3 sides :

[tex]4x+14y+4x-2y+z[/tex]

Combining like terms.

[tex]4x+4x+14y-2y+z[/tex]

[tex]8x+12y+z[/tex]

The perimeter given = [tex]10x+12y[/tex]

So, we have:

[tex]8x+12y+z=10x+12y[/tex]

Solving for [tex]z[/tex]

Subtracting both sides by [tex]8x[/tex]

[tex]8x-8x+12y+z=10x-8x+12y[/tex]

[tex]12y+z=2x+12y[/tex]

Subtracting both sides by [tex]12y[/tex]

[tex]12y-12y+z=2x+12y-12y[/tex]

∴ [tex]z=2x[/tex]

Thus, the third side is = [tex]2x[/tex]

[tex]a=-\dfrac{1}{2}[/tex]

Step-by-step explanation:

Given the parabola

[tex]y=a(x-1)(x-4)[/tex]

To find y-intercept, substitute [tex]x=0:[/tex]

[tex]y=a(0-1)(0-4)\\ \\y=4a[/tex]

Hence, [tex](0,-4a)[/tex] is the point of intersection with y-axis.

To find x-intercept, substitute [tex]y=0:[/tex]

[tex]0=a(x-1)(x-4)\\ \\x_1=1\ \text{or}\ x_2=4[/tex]

Hence, points [tex](1,0)[/tex] and [tex](4,0)[/tex] are the points of intersection with x-axis.

Find the area of the triangle formed:

[tex]A_{\triangle}=\dfrac{1}{2}\cdot \text{Base}\cdot \text{Height}\\ \\\text{Base}=|4-1|=3\\ \\\text{Height}=|4a|\\ \\A_{\triangle }=\dfrac{1}{2}\cdot 3\cdot |4a|=6|a|[/tex]

Since the area of the triangle is 3, you have

[tex]6|a|=3\\ \\6a=-3\ [\text{Parabola goes downward}]\\ \\a=-\dfrac{1}{2}[/tex]

44.9 megabytes of download is complete

Solution:

Given that,

File that is 274 megabytes is being downloaded if the download

Therefore, total megabytes of file = 274 megabytes

The download is 16.4% complete

To find: Megabytes that has been downloaded

So, we can say, 16.4 % of total megabytes of file is downloaded

Megabytes that has been downloaded = 16.4 % of total megabytes of file

Megabytes that has been downloaded = 16.4 % of 274

[tex]\rightarrow 16.4 \% \text{ of } 274\\\\\rightarrow 16.4 \% \times 274\\\\\rightarrow \frac{16.4}{100} \times 274\\\\\rightarrow 0.164 \times 274 = 44.936 \approx 44.9[/tex]

Thus 44.9 megabytes of download is complete

Final answer:

multiply 274 megabytes by 0.164, which gives 44.936 megabytes. Rounded to the nearest tenth, this is 44.9 megabytes.

Explanation:

To calculate how many megabytes have been downloaded when 16.4% of a 274 megabyte file has been completed, you simply multiply the total file size by the percentage that has been downloaded. You can convert the percentage into a decimal by dividing it by 100.

So, 16.4% as a decimal is 0.164. Now, multiply the file size by this decimal:

274 megabytes * 0.164 = 44.936 megabytes

Round to the nearest tenth, the amount downloaded is approximately 44.9 megabytes.

The number Fred thinks of is 111

Solution:

Given that, Fred thinks of a number that is greater than 110 and less than 120

He can make his number with same number of hundreds,tens and ones

To find: Fred's number

Given that the number is greater than 110 and less than 120

The possible numbers are:

111 , 112, 113, 114, 115, 116, 117, 118, 119

But he can make his number with same number of hundreds,tens and ones

So the numbers in ones, tens and hundreds place are same

So the only possible number is 111

Thus the number Fred thinks of is 111

Final answer:

Fred's number is 111, as it is the only number that is greater than 110 and less than 120 and has the same number of hundreds, tens, and ones.

Explanation:

The number Fred thinks of must be greater than 110 and less than 120. Additionally, it must have the same number of hundreds, tens, and ones. To meet these conditions, the only number that fulfills this is 111. This is because it's the only number between 110 and 120 that has the same digit in the hundreds, tens, and ones place.

Fred's number is unique in this range because it is represented with three identical digits, showcasing an interesting property of numbers in our base-ten system where a digit's value depends on its position. Hence, 111 is the number Fred is thinking of, which consists of one hundred, one ten, and one one.

Answer:

Step-by-step explanation:

First, parallel lines have the same slope, so the slopes should be the same , and then you use the given point to find the y intercept

EX:

y=x+1

find equation of line the is parallel and passes through (1, 1)

Same slope, so y=x+b

then plug in the point

1=1+b

b=0

our line would be y=x

To write the equation of a line when you know a point on the line and have the equation of a line parallel to it, use the point-slope form of a linear equation. Substitute the values and simplify to get the equation.

To write the equation of a line when you know a point on the line and have the equation of a line parallel to it, you can use the point-slope form of a linear equation. The point-slope form is y - y1 = m(x - x1), where (x1, y1) is the known point and m is the slope of the parallel line. Substitute the values into the equation and simplify to get the equation of the line.

For example, if you know a point on the line is (2, 5) and you have the equation of a line parallel to it as y = 2x + 3, the slope of the parallel line is 2. Substitute the values of the known point and the slope into the point-slope form: y - 5 = 2(x - 2). Simplify the equation to get the equation of the line: y - 5 = 2x - 4.

joshua has 3 more cookies than dareonte

Shakira played 3 full games because rounding off to 4 would increase the total.

Step-by-step explanation:

Given,

Rent of shoes = $3

Amount paid for each game = $4.75

Total paid by Shakira = $21

Let,

x be the number of games played by Shakira.

Amount paid for each game * Number of games + Rent of shoes = Total paid

[tex]4.75x+3=21\\4.75x=21-3\\4.75x=18[/tex]

Dividing both sides by 4.75

[tex]\frac{4.75x}{4.75}=\frac{18}{4.75}\\x=3.8[/tex]

Therefore,

Shakira played 3 full games because rounding off to 4 would increase the total.
