6*6*6 because the length, width, and height are all 6 meaning it is a perfect cube. All answers with four numbers are not perfect cubes, nor are ones with addition.

Answer:

6*6*6 is perfect cube .

Step-by-step explanation:

Given : Options.

To find : Which represents a perfect cube.

Solution : We have given 6*6*6 and 6+6+6 ,3*3*3*3 ,3+3+3+3+3.

Square : square of any number is multiplying a number 2 times.

Example : 2 *2 and 6 *6

Cube : cube of any number is multiplying a number 3 times.

Example : 2 *2 * 2 and 6 *6 * 6.

Therefore, 6*6*6 is perfect cube .

Answer:

Therefore

m∠Y = 41.1°

Step-by-step explanation:

Given:

In Δ YSE ,

m∠S = 70°

YE = 10 = side opposite to ∠Y

SE = 7 = side opposite to ∠S

To Find:

m∠Y = ?

Solution:

In Δ ABC, Sine Rule says

$\dfrac{a}{\sin A}= \dfrac{b}{\sin B}= \dfrac{c}{\sin C}$

So here In Δ YSE,

$\dfrac{YE}{\sin S}= \dfrac{SE}{\sin Y}= \dfrac{YS}{\sin E}$

substituting the given values we get

$\dfrac{10}{\sin 70}= \dfrac{7}{\sin Y}\\\\\sin Y=\dfrac{0.939\times 7}{10}=0.6577\\\\Y=\sin^{-1}0.6577=41.1\°$

Therefore

m∠Y = 41.1°

A number is picked randomly in the range [2,8]. If past selection indicates that the numbers picked are less than 5, what is the

yawa3891 [41]

Answer:

a) P = 2/7

b) P = 4/7

c) P = 1/7

Step-by-step explanation:

In the range of [2,8], we have the following integers which are: 2, 3, 4, 5, 6, 7, 8. So this is a total of 7 integers.

a) We look for the probability that the numbers are less than 4, so we conclude that there are possible numbers 2 and 3 out of possible 7, so the required probability is equal to P = 2/7.

b) We look for the probability that the numbers are greater than 4, so we conclude that there are possible numbers 5, 6, 7, 8 out of possible 7, so the required probability is equal to P = 4/7.

c) Based on the previous two examples, we conclude that the required probability is P = 2/7· 1/2=1/7.

Canada has a population that is about 1/10 as large as the united states. If canadas population is about 32 million, about how m

Mice21 [21]

Call Canada's population $c$ , and call the U.S. population $u$ .

We see that $c=\frac{u}{10}$ . Substituting 32 million for c, we see that $32,000,000=\frac{u}{10}$ . Multiplying by ten, we see that $320,000,000=u$ . By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
