Given :
The admission fee at a small fair is $1.50 for children and $4.00 for adults.
On a certain day, 2,200 people enter the fair and $5,050 is collected.
To Find :
How many children and how many adults attended.
Solution :
Let, number of children and adults attended are c and a.
So, c + a = 2200 ....1)
Now, fair collected is given by :
1.5c + 4a = 5050 ....2)
Putting value of a from equation 1) to 2), we get :
1.5c + 4( 2200 - c ) = 5050
1.5c - 4c = 5050 - 8800
2.5c = 3750
c = 1500
a = 2200 - 1500
a = 700
Therefore, 1500 children and 700 adults attended the fair.

Aaron has three slabs of beeswax. He plans to melt them and use all of the wax to form 36 candles. If all the candles are the same size and weight, how much will each candle weigh?
Weight of slab of beeswax isn't given.
Assume slab of beeswax = 36 gram.
Answer:
3 gram
Step-by-step explanation:
Each slab of beeswax = 36 gram
Total weight of all 3 slabs = (3 * 36) = 108 g
Number of same-sized candles to make = 36
The weight of each candle will be ;
Total weight of slabs / number of candles
108 g / 36
= 3 grams

At T-Shirts R Us, the cost to make new shirts is $1.50 per shirt plus a $50 set-up fee. At T-Shirt Planet, the set-up fee is $75 and $1 per shirt. Find the number of shirts you can order so that the cost at both companies is the same.
Answer: The number of shirts you can order = 40
Step-by-step explanation:
Let x = Number of shirts
At T-Shirts R Us,
Total cost = 50+1.50x
At T-Shirt Planet,
Total cost = 75+x
As per given, when the cost at both companies is the same then
[tex]1.50x+50=x+70\\\\\Rightarrow\ 1.50x-x=70-50\\\\\Rightarrow 0.50x=20\\\\\Rightarrow\ x=\dfrac{20}{0.50}=40[/tex]
Hence, the number of shirts you can order = 40
Which of the polygons has the greatest area?
Group of answer choices
A square with side length of 4.6 inches.
A triangle with a base of 7.18 inches and a height of 5.4 inches.
A parallelogram with a base of 5.875 inches and a height of 3.5 inches.
A rectangle that is 3.25 inches wide and 6.1 inches long.
Answer:
A triangle with a base of 7.18 inches and a height of 5.4 inches
Step-by-step explanation:
You have to multiply 7.18 by 5.4
7.18*5.4=38.772
If you do the math to the other equations, they are all less then the triangle.

Answer:
x = 80
measure of exterior angle = 112°
Step-by-step explanation:
32 + x = 2x - 48 (because the measure of exterior angle is equal to the sum of the two interior angles)
32 + x = 2x - 48
32 = x - 48
x = 80
plug in,
2(80) - 48
160 - 48 = 112

6x+5-4y-2x+y=
PLEASE HELP ME I NEED IT ASAPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!
Answer:
There is no way to solve this for x or y, as only one relationship between those variables is provided. We can, however simplify that expression.
6x + 5 - 4y - 2x + y
group like terms:
= 6x - 2x - 4y + y + 5
add like terms together
= 4x -3y + 5
And that is as much as can be done with just that expression.
The simplest form of the given equation 6x+5-4y-2x+y is 4x - 3y + 5.
What is simplification?A mathematical expression is simplified when it is replaced with a simpler, typically shorter, equivalent statement. Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
Given an expression 6x+5-4y-2x+y
simplifying it
=> 6x -2x -4y + y +5
(adding terms with same variable)
=> 4x - 3y + 5.
therefore, the simplest form of the given equation is 4x - 3y + 5.

Jason makes a fruit salad using only strawberries and blue berries. The ratio of strawberries to blueberries in Jason's fruit salad is 4 cups to 5 cups
Complete question :
Jason makes a fruit salad using only strawberries and blueberries. The ratio of strawberries to blueberries in Jason's fruit salad is 4 cups to 5 cups.
Options is in the attached picture
Which statement describes the contents of Jason's fruit salad?
Answer:
Blueberry makes up 5/9 of the fruit salad
Step-by-step explanation:
Ratio of strawberries to blue berries is 4cups to 5 cups
Hence, in a fruit salad makeup ;
We can say we have 4 cups of strawberry for every 5 cups of blue berry
Fraction of strawberry and blueberries :
Total ratio = (4 + 5) = 9
Fraction of strawberry = 4/ 9
Fraction of blueberry = 5/9
Hence, from the option , the statement ;
Blueberry makes up 5/9 of the fruit salad is true since both are the only ingredients used

Find the value of x and y
Answer:
y = 23
x = 28
Step-by-step explanation:
Find y first.
3y + 5y - 4 = 180 The two angles are supplementary if the all the lines are parallel. Combine the left side.
8y - 4 = 180 Add 4 to both sides
8y - 4 + 4 = 180 + 4
8y = 184 Divide both sides by 8
y = 23
====================================
Now if the lines are parallel, then 3y = 2x + 13
But we already know y
3*23 = 2x + 13 Do the multiplication
69 = 2x + 13 Subtract 13
56 = 2x Divide by 2
x = 56/2
x = 28
Answer:
y = 23
x = 28

What is the value of x in the figure
Answer:
x=25 I believe
Step-by-step explanation:
So, 130° should be for both the angles at the top, so that leaves 100° left for the ones at the bottom because 360 - 260 = 100
So since the 2 angles at the bottom should be equal to each other, we have 4x for the bottom 2 angles.
So, 4x = 100
So, x = 25

The picture below shows a loading platform that extends out 6 feet from the back of a truck. What is the exact length of the platform?
Answer:
really easy its 180
Step-by-step explanation:
because you multiply 30 times 6 u get 180
Answer:
5.2 ft
Step-by-step explanation:
[tex] \cos 30 \degree = \frac{6}{length \: of \: platform} \\ \\ \frac{ \sqrt{3} }{2} = \frac{6}{length \: of \: platform} \\ \\ length \: of \: platform = \frac{2 \times 6}{ \sqrt{3} } \\ \\ length \: of \: platform = \frac{12\sqrt{3} }{ 3} \\ \\ length \: of \: platform =4 \sqrt{3} \\ \\ length \: of \: platform =4 \times 1.732 \\ \\ length \: of \: platform = 5.228 \\ \\ length \: of \: platform = 5.2 \: ft[/tex]
Help me with this problem? GIVING BRAINLIEST!!
Answer:
Speed = Distance/time in km/h
a) 18 feet in 20 minutes
0.0054864 km/0.333333hours
=0.01645921645 km/h
b) 90 feet in 2.5 hours
0.027432km/2.5
=0.0109728 km/h
c) 20 yards in 1.5 hours
0.018288km/1.5
=0.012192 km/h
d) 3 2/3 yards in 15 minutes
0.003352800000003048km/0.25hours
=0.0134112

Answer:
sum of interior angles of octagon is 1080 degrees
From figure ,
136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080
so, x = 1080 - 936
= 144
Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon
Answer:
144 degrees.
Step-by-step explanation:
There are 8 sides to this polygon so the total internal of
angles = 180( 8 - 2)
= 1080
Adding up the 7 given angle we get 936
So x = 1080 - 936
= 144.
