How many blocks with dimensions of 1/3 x 1 x 1 can fit in a unit cube? A. 2 B. 3 C. 6 D. 9

Answers

Answer 1

Answer:

a block of (1/3) x 1 x 1, has a volume of, just that product, namely 1/3.

a Unit Cube, has all sides of 1 unit, thus called the Unit cube, and has a volume of 1*1*1 = 1³ = 1.

so, how many times does the volume of 1/3 go into 1?

recall there are three thirds in a whole, so 1/3 + 1/3 + 1/3 = 1, 3 times.

JKL is similar to PQR

so they want PR

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

$\sf { (PR)/(JL) = (QR)/(KL) }$

Plug in the numbers:

$\sf { (PR)/(6) = (15)/(9) }$

Cross multiply:

$\sf{ PR * 9 = 6 * 15}$

Isolate PR

$\sf{ PR = (6 * 15)/(9)}$

Simplify it

$\sf{ PR = 10}$

So your final answer is

$\boxed{\bf{10 centimeters}}$

I can only see the similar triangle problem, with sides 6cm, 9cm, and 15cm. Since the triangles are similar, the ratio for side lengths is the same. 6:9 simplifies to 2:3. If we try to solve ?:15 we get 10 as 10:15 is equivalent to 2:3, so the length is 10 cm

Answer:

e. 65,000

f. 99,000

g. 60,000

h. 80,000

i. 900,000

j. 900,000

k. 500,000

l. 700,000

Step-by-step explanation:

Since, when we round a number to the nearest thousand then we check the digit at hundred place,

If the hundred place digit is less than 5 then the number is rounded to previous thousand,

If the digit is 5 or more than 5 then the number is rounded to next thousand,

So, 65,124 ≈ 65,000

99,451 ≈ 99,000

The above procedure is follow in rounding both nearest ten thousand and hundred thousand,

But, in rounding nearest ten thousand and hundred thousand we check thousand place digit and ten thousand place digit respectively,

Hence, 60,488 ≈ 60,000

80,801 ≈ 80,000

897,100 ≈ 900,000

880,005 ≈ 900,000

545,999 ≈ 600,000

689,114 ≈ 700,000

e. 65,000
f. 99,000
g. 60,000
h. 80,000
I. 900,000
