1. The formula for calculate the perimeter of a rectangle, is:
P=2L+2W
P is the perimeter of the rectangle (P=320 feet).
L is the lenght of the rectangle.
W is the width of the rectangle.
<span>
2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
L=3W
3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:
P=2L+2W
320=2(3W)+2W
320=6W+2W
8W=320
W=320/8
W=40 feet
4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:
x=P-W
x=320 feet-40 feet
x=280 feet
<span>
How many linear feet of fence must he buy?
</span>
The answer is: 280 feet
8 25/1000 = 8.025 <===
The whole number stays to the left of the decimal...and since the 25 is over 1000, the last digit has to be in the thousandths place.
Answer:
= 11x + 2
Step-by-step explanation:
2(x+1)+9x
Distributive property
= 2x + 2 + 9x
Simplifying
= 11x + 2
Answer:
x = 11°
4x = 44°
Step-by-step explanation:
Line BC || Line EF... (given)
BF is transversal.
is exterior angle of 
Hence, by remote interior angle theorem of triangle, we have:
Answer:
Step 1: Fill three gallon jug
Step 2: Pour the water from the three gallon to the five gallon jug
Step 3: Refill three gallon jug
Step 4: Pour three gallon jug into five jug until full (this leaves one gallon in the three gallon tank.
Step 5: Dump out the water in the five gallon jug
Step 6: Pour the 1 gallon of water into the five gallon jug
Step 7: Refill the 3 gallon jug
Step 8: Pour the 3 gallons into the five gallon jug (3 + 1 = 4)
Step 9: Place jug on scale.
Hope this helps!
