If the shaded cross sections of the solids have the same area, which of the following corresponds to the value of a: the side le

Nikolay [14]

Answer:

$4\sqrt{\pi}$

Step-by-step explanation:

The cross section of a sphere is a circle with area $\pi r^2$ , where radius is given as 4
The cross section of the cube is a square with area $a^2$ , where a is side length of square

The circle area = the square area. Thus we have:

$\pi r^2 = a^2 \\\pi(4)^2=a^2\\16\pi=a^2\\\sqrt{16\pi}=a\\ a=\sqrt{16} \sqrt{\pi} \\a=4\sqrt{\pi}$

M is directionly proptional to r squared

sergejj [24]

9514 1404 393

Answer:

A) 504

B) 8

Step-by-step explanation:

The statement of proportionality can be written as the equation ...

m = kr²

Then we can find k from ...

k = m/r² = 14/2² = 7/2

That is, ...

m = (7/2)r²

Using this relation, we can find m for r=12:

m = (7/2)·12² = 7·72

m = 504 . . . for r = 12

And, we can use the same equation to solve for r when m=224.

224 = 7/2·r²

r² = 64

r = √64

r = 8 . . . for m = 224

The distance from Gillette, New Jersey, to Irvington, New Jersey, is 1 mile more than four times the distance from Irvington to

vivado [14]

Answer:

distance from Irvington to Newark

.= 3 Miles

Step-by-step explanation:

distance from Irvington to Newark.= X

distance from Gillette, New Jersey, to Irvington, New Jersey,= y

Y= 1+4x

total distance from Gillette to Newark

= z

Z= 6x-2

But total distance = x+y

Total distance= x+1+4x

Total distance= 1+5x

1 +5x= 6x-2

1+2= 6x-5x

3= x

distance from Irvington to Newark.= X

distance from Irvington to Newark

.= 3 Miles

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4x

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+4(3)

distance from Gillette, New Jersey, to Irvington, New Jersey,= 1+12

distance from Gillette, New Jersey, to Irvington, New Jersey,= 13 miles

Total distance= 1+5x

Total distance= 1+5(3)

Total distance= 16 miles

What number reduced by 14 percent equals 3440?

Wewaii [24]

Answer:

4000

Step-by-step explanation:

100 - 14 = 86

Here we shall take 86 to obtain the number easily

X × 86/100 = 3440

X = 3440 × 100 / 86

So X = 40 × 100

X = 4000
