y = ( 48 *2 ) / 6
Step-by-step explanation:
If y varies directly as x they are directly proportional, which means they relate to each other in the same way....
2 : y = 6: 48
what is y if x = 2?
The value of y can be found if you write it a two fracrions
2 : y = 6 : 48
2 / y = 6 / 48
cross multiply the fractions gives
6*y = 48 *2
divide left and right of the = sign by 6 gives the answer:
y = ( 48 *2 ) / 6
(if you solve it you get y = 12 but that was not the question).
Other method:
multiply left and right of the = sign by y
2 * y/y = y *6 / 48
6y / 48 = 2 * 1
multiply left and right of the = sign by 48
6y * 48/48 = ( 48 *2 )
6y = ( 48 *2 )
divide left and right of the = sign by 6
6/6* y = ( 48 *2 )/6
y = ( 48 *2 ) / 6
(if you solve it you get y = 12 but that was not the question).
Answer: 1773.6 yards 5320.8 feet 64324.8 inches
Step-by-step explanation:
1 mile in yards = 1760 40.8 feet in yards = 13.6 1760 + 13.6 =<u> 1773.6 yards </u>
1 mile in feet = 5280 + 40.8 = <u> 5320.8 feet </u>
1 mile in inches = 63360
40.8 feet in inches = 964.8
63360 + 964.8 = <u>64324.8 inches </u>

If this item has the same picture on the same question posted before, the following will be the data.
Given: NB = 12 ft, Angle-120°<span>
Asked: area of the region that is not shaded.
Substitute the given values in the equation in finding the area of a circle.
</span>A = πr²
<span>A = ⅔π(12 ft)² </span>
<span>A = 96π ft²
(Since </span>120° is 1/3 of the circle. it is then understood that the unshaded parts must be 2/3 of the circle.)
Since you already have the area, find the area of the triangle to add it to the area of the circle to find the area of the unshaded part. By using a handy trigonometry, you can tell that their will be 2 triangles of 12 ft (if you are going to divide 120° angle). From this, you'll see that there will be one of the smaller triangles having a <span> the height of 6 ft and the base is 6√3 ft. Substitute the values.</span>
A = ½bh
<span>A = ½(6 ft)(6√3 ft) * 2 </span>
<span>A = 36√3 ft²
</span>
Add them up and you will have the exact answer 96π + 36√3 ft², when rounded to the nearest tenth, you will have <span> 364 ft². </span>
Answer:
x=3.15
Hope this helps... the part with the 2 9/20 had me a bit confuzzled XD
The volume of the resulting solid will be the volume of one rectangular prism times n.
The the volume of a rectangular prism is V=lwh. But since l=w (cross-section is a square), we now have V=l²h.
The volume of the resulting solid will be V = nl²h or V = nw²h.
