Answer:

384\ in^{2}

Step-by-step explanation:

Hello, I think I can help you with this

Let's remember

the area of a square is = side * side=side2

the number of faces of a cube = 6

So, the total area of a cube will be

the area of a square*the number of faces of a cube=side*side*6

A_{t}=side^{2} *6\\

Step 2

put the values into the equation

let

side = 8 in

A_{t}=side^{2} *6\\A_{t}=( 8\ inch)^{2} *6\\A_{t}=64\ inch^{2} *6\\\ A_{t}=384\ inch^{2}

Have a great day

The surface area is the sum of the are of all sides. One side's area is 64 in^2 and since it's a cube, all sides will be the same.
64*6 = 384
The surface area is 384 in^2

The rectangular top of a small box has dimensions of one 40 mm x 230 mm. How long in centimeters with a ribbon need to go all th
kozerog [31]

Answer:

540 mm

Step-by-step explanation:

Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm

We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the

P=2 (l+w)

l = 230

w = 40

P=2(230+40)

P=2 x 270

P= 540

Hence we need 540 mm of ribbon  to go all the way around the edge of the top of the box.

guapka [62]

Answer:

here it's 124°F so if we subtract 8 in 124 it will be 124-8= 114°F

now the range = height - lowest = 124°- 114°F = 8° F

Use the equation to complete an algebraic proof that proves the answer is x = 7/6. Write your proof in your journal and upload y
Komok [63]

Answer:

x=7/6

Step-by-step explanation:

subtract the 4x from both sides of the equation

(2x+6)-4x=4x-3-4x

find common denominator

(2x+6)/5+(5(-4)x)/5=4x-3-4x

then combine fractions

(2x+6+5(-4)x)/5=4x-3-4x

then multiply the 5&4

(2x+6-20x)/5= 4x3-4x

combine terms

(-18x+6)/5= -3

then multiply everything by 5

-18x+6= -15

subtract the 6 from both sides

-18x= -21

divide -21 by -18

(-21)/(-18)=x

find greatest common multiple (3) and solve

x = 7/6

I need help on this homework question please
zheka24 [161]

(a) In functional notation, you are asked for C(600).

For this, put 600 where t is in the functional notation C(t).

(b) The value multiplying 8 is 0.5 when the exponent of 0.5 is 1. That is

... t/5730 = 1

Multiplying by 5730 gives

... t = 5730

It will take 5730 years for half the Carbon 14 to be gone.

___

Or, you can recognize a fraction is 1 when its numerator is the same as its denominator. That is t/5730 = 5730/5730 = 1 when t=5730.
