The admission fee at a small fare is $1.50 for children and four dollars for adults. One certain day $5050 is collected. If 1000 adults attended the fair right and solve the Larry Quetion to find the number of children that attended
700 children attended the fair
Solution:
Let "a" be the number of children attended
Let "b" be the number of adults attended
Cost for each children = $ 1.50
Cost for each adult = $ 4
1000 adults attended the fair
b = 1000
One certain day $5050 is collected. Therefore, we frame a equation as:
number of children attended x Cost for each children + number of adults attended x Cost for each adult = 5050
[tex]a \times 1.50 + 1000 \times 4 = 5050\\\\1.5a + 4000 = 5050\\\\1.5a = 5050 - 4000\\\\1.5a = 1050\\\\Divide\ both\ sides\ by\ 1.5\\\\a = 700[/tex]
Thus 700 children attended the fair
Danica is in the observation area of the sears tower in chicago overlooking lake michigan. She sights two sailboats going due east from the tower. The angles of depression to the two boats are 42 degrees and 29 degrees. If the observation deck is 1,353 feet high, how far apart are the boats?

Lydia decides to provide cheddar cheese for the competition. She buys 4.2 kilograms for 39.90. She estimates the cost of 1 kilogram of cheese to be $1. Is her estimate reasonable?
The rate of cheese is $9.5 per kilogram which does not match Lydia's estimation.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
Lydia decides to provide cheddar cheese for the competition. She buys 4.2 kilograms for 39.90.
She estimates the cost of 1 kilogram of cheese to be $1.

Allen and Beverly thought of the same number. Allen doubled the number and added 15 to the result. He got 51. Beverly performed the same operations with the number, but in reverse order. What did she get?
Allen and Beverly both thought of the number 18. When Allen doubled the number and added 15, he got 51. Beverly, in reverse order, subtracted 15 from the number and then doubled it to get 6.
Let the number that Allen and Beverly thought of be represented by 'x'.
Allen doubled the number and added 15 to the result, which gives us the equation:2x + 15 = 51
Now, we need to solve for 'x' to find the original number.
Subtract 15 from both sides of the equation: 2x = 51 - 15
2x = 36
Now, divide both sides by 2 to isolate 'x': x = 36 / 2
x = 18
So, Allen and Beverly both thought of the number 18.
Now, Beverly performs the same operations but in reverse order: 1. She starts with the number 18.
2. She subtracts 15 from it:18 - 15 = 3
3. Then, she doubles the result:2 * 3 = 6
So, Beverly gets the result of 6 by performing the same operations in reverse order.

Choose any model to solve the problem. Show your work to justify your answer.
Lee sold 60 magazine
Step-by-step explanation:
Terrence and Lee were selling magazines for a charity
In the first week, Terrance sold 30% more than LeeIn the second week, Terrance sold 12 magazines, but Lee did not sell anyTerrance sold 50% more than Lee by the end of the second weekWe need to find how many magazines Lee sold
Assume that Lee sold x magazines
∵ Terrance sold 30% more than Lee in the first week
∵ Lee sold x magazines in the first week
- Find 30% of x and add it to x to find how many magazines
Terrance sold
∵ Terrance sold = 30% × x + x
∴ Terrance sold = [tex]\frac{30}{100}[/tex] × x + x = 0.3 x + x
∴ Terrance sold = 1.3 x magazines in the first week
∵ Terrance sold 12 magazines in the second week
- Add 1.3 x to 12 to find the number of magazines that Terrence
sold in the two weeks
∴ Terrence sold 1.3 x + 12 magazines in the two weeks
∵ Lee did not sell any in the next week
∴ Lee sold x magazines in the two weeks
∵ Terrance sold 50% more than Lee by the end of the 2nd week
- Equate 1.3 x + 12 by the sum of x and 50% of x
∴ 1.3 x + 12 = 50% × x + x
∵ 50% × x = [tex]\frac{50}{100}[/tex] × x = 0.5 x
∴ 1.3 x + 12 = 0.5 x + x
- Add the like terms in the right hand side
∴ 1.3 x + 12 = 1.5 x
- Subtract 1.3 x from both sides
∴ 12 = 0.2 x
- Divide both sides by 0.2
∴ 60 = x

The base of an isosceles triangle is 7 units.
What could the length of the other sides be?
In an isosceles triangle with a base of 7 units, the two other sides have to be greater than 3.5 units but less than 7 units due to the triangle inequality theorem, which means each side must always be shorter than the sum of the other two sides.
Explanation:An isosceles triangle is a triangle with two sides of equal length. If the base of the triangle is 7 units, the lengths of the other sides could be any value greater than 3.5 units but less than 7 units. This principle is rooted in the triangle inequality theorem which states that any side of a triangle always needs to be shorter than the sum of the other two sides.
So in this case, since the base is 7 units, the other two equal sides (let's call them 'a' and 'b') could be, for example, 5 units each, but don't forget they must fulfill two conditions: firstly, 'a' + 'b' > 7 (which is true if both 'a' and 'b' are more than 3.5 units), and secondly, 'a' + 7 > 'b' as well as 'b' + 7 > 'a' (which are true as long as 'a' and 'b' are less than 7 units). Consequently, both 'a' and 'b' could be a range of lengths, but they must be greater than 3.5 units and less than 7 units in order to ensure that the triangle inequality theorem is respected.

a) angle 4
b) angle 6
c) angle 8
2)Describe the sequence of transformations from quadrilateral WXYZ to W” X” Y” Z”.
Answer:
i) angle 3 is 120°
ii) angle 3 + angle 4 = 180° as both angles make up a staright line
∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°
iii) angle 6 = angle 3 = 120° as they are opposite interior angles
iv) angle 6 + angle 8 = 180° as both angles make up a straight line
∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°
Step-by-step explanation:
i) angle 3 is 120°
ii) angle 3 + angle 4 = 180° as both angles make up a staright line
∴ angle 4 = 180° - angle 3 = 180° - 120° = 60°
iii) angle 6 = angle 3 = 120° as they are opposite interior angles
iv) angle 6 + angle 8 = 180° as both angles make up a straight line
∴ angle 8 = 180° - angle 6 = 180° - 120° = 60°

What is the slope Intercept form of 8x-2y=-72
Answer:
y = 4x + 36
Step-by-step explanation:
To find the equation in slope-intercept form, rearrange to isolate "y".
Slope-intercept form is y = mx + b. The variables mean:
"x" and "y" - points that are on the line, or solutions.
"m" - the slope, how steep the line is
"b" - the y-intercept, when the line touches the y-axis
Isolate "y".
8x - 2y = -72
8x - 8x - 2y = -72 - 8x Subtract 8x from both sides.
-2y = -72 - 8x Left side : 8x - 8x = 0
[tex]\frac{-2}{-2}y = \frac{-72}{-2} - \frac{8}{-2}x[/tex] Divide both sides by -2
y = 36 - (-4)x Simplify the fractions
y = 36 + 4x Remember two negatives make a positive, add 4x.
y = 4x + 36 Put "4x" in front of 36. It looks like y = mx + b now.
"m" would be 4.
"b" would be 36.

The value of [tex]m[/tex] cannot be equal to 0. In other words,
[tex]m\:\ne \:0[/tex]
Step-by-step explanation:
Considering the function
[tex]f(x) = mx + b[/tex]
Lets find the inverse of this function.
Suppose
[tex]y=f\left(x\right)[/tex][tex]y=mx+b[/tex]Lets exchange the variables [tex]x[/tex] and [tex]y[/tex] such as
[tex]x=my+b[/tex]
Lets isolate the variable [tex]y[/tex]
[tex]my=x-b[/tex]
[tex]y=\frac{x-b}{m}[/tex]
Suppose
[tex]f\left(x\right)^{-1}=y[/tex]
As
[tex]y=\frac{x-b}{m}[/tex]
So, inverse function is
[tex]f\left(x\right)^{-1}=\frac{x-b}{m}[/tex]
As the denominator [tex]m[/tex] cannot be zero in the inverse function.
Thus, the value of [tex]m[/tex] cannot be equal to 0. In other words,
