Answer:
$6.50 per bag of popcorn
Step-by-step explanation:
let a bag of popcorn be represented by p and a candy bar be b
28p + 40b= $282
17p + 20b= $160.50
this is an example of stimatanelous equations
so you have to double the second equation to give 34p + 40b =$321
subtract the equations to give one
6p =$39
divide $39 by 6 to give the value of one bag of popcorn = $6.50

A famous monument is 300 ft tall. When it casts 210-ft shadow, a nearby tree casts a shadow that is 27 ft long. About how tall is the tree?
Answers
Answer:
38.57 feets
Step-by-step explanation:
Given that:
Height of monument, h = 300ft
Shadow of monument, s = 210 ft
Shadow of tree, s = 27ft
Height of tree, = x
Using the relation :
Height / shadow = height / shadow
Monument = tree
300 / 210 = h / 27
Cross multiply
300 * 27 = 210 * h
8100 = 210h
h = 8100 / 210
h = 38.57 feets

HELP PLS use the original price and markup to find the retail price. original price $68 markup 20%
Answers
Answer: $81.60
Step-by-step explanation:
When we have an original price OP, and a markup of X% (this is how much increases the price with respect to the original price)
The retail price will be:
RP = OP + (X%/100%)*OP
RP = OP*(1 + X%/100%)
In this case, we have:
Original price = OP = $68
markup = X% = 20%
Replacing these in the above equation, we get:
RP= $68*(1 + 20%/100%) = $68*(1 + 0.20)
RP = $68*(1.20) = $81.60
Then the retail price of this particular item is $81.60

Answer:
B. y = 3x + 1
Step-by-step explanation:
We can look at the table like a bunch of values, where (x) is what is inserted into the equation, and (y) is what comes out.
Now, simply insert the (x) values into each equation and see if they work out or not.
y = (1/3)(-1) + 1 does not equal -2, meaning this equation is defunct.
y = 3(-1) + 1 = -2; y = 3(0) + 1 = 1. This must be the equation as it works for the (x) values given. You can try the other equations, but a simple look at them is all you need to prove them false.

Step-by-step explanation:
Calculating, the rate was found out to be
y= 2.5x
Let y1= 0, y2= 10
x1= 0, x2= 4
(y2-y1)/(x2-x1) = (y- y1)/(x- x1)
(10-0)/(4-0) = (y-0)/(x-0)
10/4 = y/x
y= (10/4)x= 2.5x
On a map of hiking trails, 0.5 inch represents 1 mile. A trail is shown as 1.25 inches long on the map. How long is the actual trạil?
Answers
Answer:
2.5 miles
Step-by-step explanation:
Answer:
The actual trail length is 2.5 miles.
Step-by-step explanation:
Let's solve this. 0.5 inches on the scale = 1 mile. Since the trailer is 1.25 inches long on the scale, let's first multiply 0.5 by 2. You would get 1 inch on the scale, which would be 2 miles.
2 miles = 1 inch on the scale. But it says 1.25, so since 0.5 inches is 1 mile, then 0.25 inches is 0.5 miles. Add 2 miles and 0.25 miles, and you will get 2.5 miles.
The trailer length is 2.5 miles.

After transformation the triangle A'B'C'.
Coordinates A' = (-1, -1), B(-1, 5) and C'(-4, 6)
The scale factor is 1/2.
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.
Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 180 degrees.

At a wedding reception, the caterer served fishing chicken. The fish dinner cost $12 per person in the chicken cost $9 per person. The caterer charged 2544 total for the dinner. If 232 people went to the reception, how many people had fish how many had chicken.
Answers
Answer:
80 persons haf fish and 152 persons had chicken
Step-by-step explanation:
Given data
let the number of persons that had fish be x and chicken be y
so
12x+9y=2544------------------1
x+y= 232------------------------2
from 2
x= 232-y
substitute the value of x in 1
12(232-y)+9y=2544
2784-12y+9y=2544
2784-3y=2544
3y= 2784-2544
3y=240
y= 240/3
y=80
put y= 80 in 2
x+80= 232
x= 232-80
x=152
Hence 80 persons haf fish and 152 persons had chicken
