What is the sum of 1 2/16 + .6 + (-½)

Mashutka [201]

Answer:

1 9/40

Step-by-step explanation:

Any calculator can tell you the sum is ...

1 + 2/16 + 0.6 - 1/2 = 1.225

The decimal fraction can be reduced, if you like:

225/1000 = (25)(9)/(25(40)) = 9/40

As a mixed number, the sum is 1 9/40.

Alternate solution

1 2/16 + 0.6 -1/2 = 1 1/8 + (6/10 -5/10) = 1 1/8 + 1/10

= 1 + (1/8 +1/10) = 1 +(5/40 +4/40) = 1 9/40

A sphere has a radius of 4 inches. What is the surface area of the smallest cube that could circumscribe the sphere?

vovikov84 [41]

Answer:

$SA=384\ in^2$

Step-by-step explanation:

we know that

The smallest cube that could circumscribe the sphere has a length side equal to the diameter of the sphere

In this problem

The radius of the sphere is $r=4\ in$

The diameter of the sphere is two times the radius

$D=2r=2(4)=8\ in$

The length side of the cube is

$b=8\ in$

Remember that

The surface area of a cube is equal to the area of its six faces

$SA=6b^2$

substitute the value of b

$SA=6(8)^2$

$SA=384\ in^2$

Help please, just number 3, thats all im asking, thanks.

The rectangle that has area 400 has width 10, so its length is 40.

A = LW; L = A/W = 400/10 = 40

The length is 10 + 0.2 = 10.2. The width is 10 + 2 = 12

The multiplication is 10.2 * 12

40.2 * 12 = 40 * 10 + 0.2 * 10 + 40 * 2 + 0.2 * 2

40.2 * 12 = 400 + 2 + 80 + 0.4

40.2 * 12 = 482.4
