7. Answer is D! 1 to the 3rd power, 1^3, or 1 cubed as you'll hear it, is 1 because when something is cubed that means it's times itself 3 times. (EX: 4^3 = 4x4x4) 2 cubed is 8. 3 cubed is 27. 4 cubed is 64 and 5 cubed is 125!

8. Answer is C! A is gaining speed and B is the capped speed, meaning it can't get any higher, and C is the loss of speed.

Write a rule describing the results when one multiplies three positive and negative decimals and changes the order of multiplica
anygoal [31]

Answer:

2 positive * 1 negative = negative

2 negative * 1 positive = positive

Step-by-step explanation:


one positive and 2 negative

(+ * -) * - =

positive times negative = negative * negative = positive

(+ * -) * -  = +

now if we change the order by putting parenthesis

+ *( - * -)

negative time negative = positive

+ * (+) = positive

the result is positive


The result does not change because of where we put the parentheses.


- * + * + =

negative  times positive = negative

negative * positive= negative

- * + * + =  negative

The order does not matter

At a two-hour basketball practice, Tracy can either choose to run miles, which take six minutes per mile, or play scrimmage game
Lera25 [3.4K]

Answer:

See the image attachment. It shows the three inequalities

6m+30s \le 120

0 \le m \le 5

s \ge 0

the inequalities are all stacked on each other with a large curly brace written off to the left

===========================================

Explanation:

Let,

m = number of miles Tracy runs

s = number of scrimmage games Tracy plays

m and s are integers

-------

Each mile takes 6 minutes, so running m miles takes up a total of 6m minutes.

Each scrimmage game takes 30 minutes, so in total she uses up 30s minutes of time if the number of games she plays is 's'.

In total, Tracy uses up 6m+30s minutes running and playing scrimmage games. The max time allotted for her is 2 hours or 120 minutes. Therefore, 6m+30s \le 120 is one inequality that makes up the system of inequalities.

-------

We know that 'm' is positive, and we also know that m cannot get larger than 5, so we can write 0 \le m \le 5. This says "m is between 0 and 5 including both endpoints".

-------

For similar reasons in the last section above, we also know that 's' is positive as well; however we have no upper bound restrictions on 's'. So we simply say s \ge 0

-------

Overall, the system of inequalities has these three inequalities:

6m+30s \le 120

0 \le m \le 5

s \ge 0

they are all stacked on each other and written with a large curly brace to the left hand side of this stack. The large curly brace is just a way of keeping things together in a group or collection so to speak. A paired right curly brace is not included.

A visual reference of the answer is attached as an image below, just so you can see what I mean by the large curly brace.

Can you help me to get this question please
zzz [600]

Part A).
If 100 fish all had the same weight, and they weighed
235 pounds when they were all on the scale at the
same time, then each fish weighed

               235 / 100  pounds .

Part-B). 
You can find that actual weight with your calculator.

                 235 / 100  =  2.35 pounds .

Part-C).
If there were only 10 fish but their total weight was still 235 pounds,
then each fish would have to weigh a lot more, to make up the same
weight with only 10 of them.

Now, each fish would have to weigh   235 / 10 pounds .

That number is        235/10  =  23.5 pounds.

If there were only 1/10 as many fish, then in order to add up to the
same total weight, each fish would have to be 10 times as heavy.
