Answer:
139.48
Step-by-step explanation:
cos(55)=80/x
80/cos(55)=x
My late response (haha): First, you would write a proportion.
Step 1: 2496 over 48 = x over 31
(x represents the area of the land that is not fenced).
Step 2: Cross multiply
2496 times 31 and x times 48
Step 3: Calculate
77376 = 48x
Step 4: Divide both sides by 48
77376/48 = 1612
48x/48 = x
Step 5: Write it as a sentence
The area of the land that is not fenced is 1612 squared meters.
Hope that helped! Good luck! :]
Answer:
D r = 4 − 4 cos(θ)
Step-by-step explanation:
Right on edge
Perimeter = 2*(length +width)
perimeter = 2*(3x + (3x +(2x+6)))
.. = 2*(3x +3x +2x +6)
.. = 2*(8x +6)
perimeter = 16x +12
If x=3, the perimeter is 16*3 +12 = 60 inches.
Mathematical Answer: 2cups*3/4 = 1 and 1/2 cups or 1.5 cups.
How to do it while cooking:
- Get out a container large enough to hold at least 4 cups sauce
- Get out a "1 cup" and "1/2 cup" measuring cup.
- Measure out 1 cup of sauce with the "1 cup" measuring cup.
- Measure out 1/2 of a cup of sauce with the '1/2 cup' measuring cup.
- pour both cups into the larger container.
And there you go you have 3/4 of 2 cups of sauce.
