Answer:

The inverse operation of squaring a number is finding the square root of a number. The square root cancels out the square. For example, 3² = 9. To cancel out the square, we have to take the square root. So, √9 = 3. Hope this helped.Step-by-step explanation:

Answer:

$\frac{72}{462}$ or $\frac{12}{77}$ (simplified)

Step-by-step explanation:

Based on the information provided within the question it can be said that in order to calculate the probability of both grapes being green we need to find the probability of each grape being green separately and then multiply those probabilities together

In the first choice, there are a total of 22 grapes (9+13), 9 of which are green. Therefore the probability of the first chosen grape being green is $\frac{9}{22}$

In the second choice,since we removed one grape there is now a total of 21 grapes (22-1), 8 of which are green. Therefore the probability of the second chosen grape being green is $\frac{8}{21}$

Now we multiply both probabilities together to calculate the probability that both grapes are green in a sequence.

$\frac{9}{22} * \frac{8}{21} = \frac{72}{462} or \frac{12}{77}$

a train is traveling from New Orleans to Memphis at a constant speed of 79 miles per hour.New Orleans and Memphis are 395.1 mile

alexdok [17]

Just use the formula time = distance / speed

395.1/79= 5.001

It will take the train approximately five hours to reach Memphis

Answer:

Step-by-step explanation:

Let's use the rule GEMDAS (Grouping, Exponents, Multiply, Divide, Add, Subtract) from left to right. Therefore, we will simplify the equation in the parentheses. $2^{3} = 8. (1-8= -7)$ . -(-7) creates a double negative, deeming the 7 positive, because when there is two negatives the number will turn into a positive. $7^{2}$ = 49, -3 x 4= -12. Therefore the final form of the equation will be 49 - 12 = 37.

Let me know if there are mistakes.
