Answer: w =1 L=6
Step-by-step explanation:
What is Perimeter = 2 L + 2W
2L + 2B =14
L = 2W + 4
2(2W + 4) + 2W = 14
4W +8 +2W =14
6W=14-8
W=1
L=2W +4= 6

That's the arc length of the whole circle, i.e. the arc length of 360°.
65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.6991118431 is
6.8067840827819444444444444444444. Rounded to the nearest hundredth, the answer is 6.81 inches.
That's real pi, lets see if it makes a difference to use "stupid pi".
C=2πr
C=2π6
C=37.68
That's the arc length of the whole circle, i.e. the arc length of 360°.
65° is 18.055555555555555555555555555556% of 360°, (65/360*100)
so 18.055555555555555555555555555556% of 37.68 is
6.803333333333333333333333. Rounded to the nearest hundredth, the answer is 6.80 inches.
Yep makes a difference. That's why you don't use stupid pi. 3.14159 is what we always used in engineering, or just the pi button and using a ton of digits.
Answer: 6.80 inches.
To add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer
so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work
so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)
so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315
we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315

Answer:
No, doubling the base and height would actually quadruple the area,
Step-by-step explanation:
With the original measurements of b = 3 ft and h = 5 ft,
<em>b x h = A</em>
<em>(3) x (5) = </em><em>15 ft</em>
So lets say we <em>doubled</em> the factors:
<em>(2)(3) x (2)(5) = A</em>
We would end up with 60 feet, four times that of 15.
<em>(6) x (10) = </em><em>60 ft</em>
