Answer:
7.2%
Step-by-step explanation:
Given data
Estimate=450miles
Actual= 485 miles
%error= actual-estimate/ actual*100
%error=35/ 485*100
%error=0.072*100
%error=7.2%

Answer: The length and width are 50 and 30 meters (or 30 and 50 meters).
Step-by-step explanation:
To solve this question, we can represent variables for the length and width in two equations.

To solve for one of the variables, you'll have to substitute one of the variables, so solve for one of them:


Now, we have a standard quadratic equation that we can factor. When factoring, you'll get this:

This tells us that the width could be either 50 or 30.
Substitute 50 into one of the equations to find the length:
2 (l) + 100 = 160
l = 30.
The length and width are 50 and 30 meters (or 30 and 50 meters).
Answer:
Step-by-step explanation:
Let x = the number of pepper plants, then (x + 6) = the number of tomato plants. Since the ratio of tomatoes to peppers is 5:2, we have the following:
5/2 = (x + 6)/x
2x + 12 = 5x
12 = 3x
4 = x = the number of pepper plants
Well this is simple all you have to do is subtract 6 dollars from 35 lets do that first
35 - 6 = 29
so she has 29 dollars to spend on each friend and she only has two....
so lets divide 29 and 2
29/2 = 14.5
so she can spend $14.50 on each of her friends:)
