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?
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.

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.

HELP PLS use the original price and markup to find the retail price. original price $68 markup 20%
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

10. Harmony places the letters in the word DECEMBER into a bag. A letter will be randomly
selected and not replaced. Then another letter will be selected. What is the probability of
Hormony selecting a C and then an E?
Answer:
3/56
Step-by-step explanation:
There are 8 letters in the word DECEMBER. The probability of picking a C first is 1/8, since there's only one C. Since the letter is not replaced, there are now 7 letters to choose from, out which 3 of those are the letter E. Therefore, the probability of picking an E second is 3/7. The total probability then is equal to [tex]\frac{1}{8}[/tex] times [tex]\frac{3}{7}[/tex], which is equal to [tex]\frac{3}{56}[/tex].
Hope this helps! :D

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.
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

find the 29th term of the arithmetic sequence 182,176,170
9514 1404 393
Answer:
14
Step-by-step explanation:
The first term of the sequence is 182, and the common difference is 176-182=-6. So, the general term is ...
an = a1 +d(n -1)
an = 182 -6(n -1)
The 29th term will be ...
a29 = 182 -6(29 -1)
a29 = 14

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?
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

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
