Answer:

<em>The stack of blocks is 25.96 inches tall</em>

Step-by-step explanation:

<u>The Volume of a Cube</u>

Given a cube-shaped figure of side length L, the volume is calculated by:

V=L^3

If the volume is known, then the side length can be found by solving for L:

L=\sqrt[3]{L}

We are given three cube-shaped blocks with known volumes. We'll find the individual side lengths and add them up to find the height that results when they stack up vertically.

Block 1, volume 375 cube inches:

L_1=\sqrt[3]{375}=7.21\ inch

Block 2, volume 648 cube inches:

L_2=\sqrt[3]{648}=8.65\ inch

Block 3, volume 1029 cube inches:

L_3=\sqrt[3]{1029}=10.10\ inch

Total height=7.21 inch+8.65 inch+10.10 inch=25.96 inch

The stack of blocks is 25.96 inches tall

Bingel [31]

Answer: (d). Area = 6.8 × 10^3 m^2 (to 2 significant figure)

Step-by-step explanation:

The area to find rectangular is:

Area = length × breadth

Area = 32.30 × 210

Area = 6783 m^2

Area = 6.8 × 10^3 m^2 (to 2 significant figure)

Sav [38]
There's a catch here, and I don't really want to go into full detail.  Because of
this catch, I think it would be unusually tough to write a simple equation for this
situation. If you wouldn't mind, let's just list it instead:

<u>After</u> . . <u>water added</u> . . <u>total in pool</u>

7 min . . . 14 gallons . . . 14 gallons
1 more . . 1 gallon . . . . . 15 gallons
7 more . . 14 gallons . . . 29 gallons
1 more . . 1 gallon . . . . . 30 gallons
5 more . . 10 gallons . . . 40 gallons, the pool is full

Add up all the minutes: <u>21 minutes</u>

Three times a number is the same as 28 more than 6 times the number. Find the number. If n is "the number," which equation could
STALIN [3.7K]
OK. Let's build this thing brick by brick,
one step at a time:

The number. . . . . . . . . . . . . . . . . . . . . . . N
==> Three times the number . . . . . . . . 3N
6 times the number. . . . . . . . . . . . . . . . 6N
==> 28 more than 6 times the number . 6N + 28

You said the three times the number is the same
as 28 more than 6 times the number.
So I can write

3N = 6N + 28

That's the equation.
Subtract 3N from each side: 0 = 3N + 28

Now subtract 28 from each side: -28 = 3N

Now divide each side by 3 : N = - 28/3 .

That number is kind of weird, but it's the ONLY number
that behaves according to the description in the question.

Three times the number . . . . . -28
6 times the number . . . . . . . . . -56

-28 is 28 more than -56. yay!

An integer is a negative or positive number. 

Since there is a loss of 8 pounds, you have to take 8 away.

The integer would be: -8

I hope this helps!
