Answer:
$2,700
Step-by-step explanation:
Let the width of the pasture be x, this means that the length of the pasture will be 2x
The area of a rectangle is L * B
Hence,
x * 2x = 18,000
2x^2 = 180,000
x^2 = 90000
x = 300 meters
This means the length is 600 metres
Now, to get the length of the fence, we need to know the actual perimeter which is 2(L + B)
= 2 ( 300 + 600)
2 * 900 = 1,800 metres
The cost is thus 1,800 * $1.50 = $2,700
Answer:
x=4
Step-by-step explanation:
Combine like terms
Subtract 4 from both sides of the equation
Simplify
Subtract 5
from both sides of the equation
Simplify
Divide both sides of the equation by the same term
Simplify
Answer:
(600 mi) × (5280 ft/mi) × (12 in/ft)
Step-by-step explanation:
A "unit multiplier" is a multiplier that has a value of 1. That is, the numerator and denominator have the same value. For units conversion problems, the numerator quantity has the units you want, and the denominator quantity has the units you're trying to cancel.
You have units of miles. You know that ...
1 mile = 5280 feet
1 foot = 12 inches
You want to get to units of inches. With these conversion factors, you can do it in two steps (as the problem requests). The first conversion is from miles to feet using the unit multiplier (5280 feet)/(1 mile). This gives you a number of feet.
Then the second conversion is from feet to inches, so you use the one that lets you put inches in the numerator and feet in the denominator:
(12 inches)/(1 foot)
When you multiplie these all out, units of miles and feet cancel, and you're left with inches.
_____
With the above conversion factors, you can write unit mulipliers of either ...
(5280 ft)/(1 mi) . . . to convert to feet
or
(1 mi)/(5280 ft) . . . to convert to miles.
The maximum cost would be 6 with the inequality 6 ≥ x representing how.
You can solve this question by first turning it into an equation. She needs to find how much she can spend for each party favor on each friend so you want to set this up as 7x=42 with c being how much is the maximum cost per friend. You then want to isolate x by dividing 7 on both sides which leaves you with x=6
Now that you know the maximum cost for each bag is 6 you need to create the inequality. Because the maximum is 6 it can also be anything lower than 6 aswell, so you can say that the inequality is 6 ≥ x.
