Answer:

  1 mile

Step-by-step explanation:

  5 × (1/5 mi) = 5/5 mi = 1 mi

The students ran 1 mile in all.

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.

HERE IS YOUR ANSWER!

Step-by-step explanation:

from the basic knowledge of Angels in a trapezium

115 + 18 y + 10y + ( 3y + 6) = 360

31y + 120 = 360

31y = 320-120

31y = 240

y = 240/31

y = 7.74

Answer:

Step-by-step explanation:

Just make the graph and compare them. Graph B. can be seen below

Answer: Well B

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

Answer:

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].

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:

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

Answer:

$26.25

Step-by-step explanation:

35(1-0.25)

= 35(0.75)

= 26.25

Answer:

Once you know the sum, you can divide that by 12 to get the measure of each interior angle: 1800°/12 = 150°

Step-by-step explanation:

Answer:

150°

Step-by-step explanation:

Corollary to the Polygon Angle-Sum Theorem (n-2)180/n

(12 - 2)180 / 8

(10)180= 180 / 8

180/8 = 150°

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

Step-by-step explanation:

5/8 of x is 1 1/4

5/8 x=1 1/4

5/8 x=5/4

x=5/4×8/5=2

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.

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
