Answer:
Tape diagram b
Step-by-step explanation:
It shows 1/3 out of 3/3 instead of 1/3 of 1/3
The expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.
Given a taxi charges $2.50 for the first mile and $0.40 for each mile
We are required to make an expression showing total cost and total cost of a 20 mile ride.
let the miles ride by tax be x.
Total cost of the product or service=Number of units*price of one units.
We have been given that $2.50 is fixed so we will not multiply our variable charge with $2.50 and multiply 0.40 with x.
So,the expression showing looks like 2.50+0.40x.
Now to find the cost when taxi travels 20 miles, we have to put x=20,
Cost=2.50+0.40*20
=2.50+(40*20)/100
=2.50+800/100
=2.50+8
=$10.50
Hence the expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

30%
percent means parts out of 100 so 30%=30/100=3/10
42 is 3/10 of x
'of' can be translated to multiply
42=3/10 times x
multiply both sides by 10/3 to get rid of fraction
420/3=x
140=x
the number is 140

Answer:
The answer to your question is below
Step-by-step explanation:
1) The triangles are similar by the AA postulate so use proportions to find x.
x/207 = 170/90
solve for x
x = 207(170/90)
x = 207(1.89)
x = 391 ft
2) These triangles are similar so use proportions to solve it
x/138 = (x + 60)/207
207x = 138(x + 60)
207x = 138x + 8280
207x - 138x = 8280
69x = 8280
x = 8280/69
x = 120
