Answer:

0.03

Step-by-step explanation:

the first thing you would do in this equation is to deal with the exponent

a negative exponent puts the number under 1

1/10^2

10^2 is also 100

1/100

3 * 1/100 is 3/100 so that is your answer

3/100 is also 0.03

Jacoby followed a recipe that requires 2 cup for water four every 3 cups of flours. if he used 8 cups flours, how many cups of w

zmey [24]

Answer:

5 and 1/3 cups of water.

Step-by-step explanation:

Set up a proportion like this:

2:3 for the original recipe

Then a second proportion for the recipe Jacoby used:

w:8 (use w for the unknown water amount)

Set up an equation so that the proportions equal each other. It helps if you write them in fraction form:

$\frac{2}{3} =\frac{w}{8}$

Use cross multiplication to get the new equation:

8 x 2 (or 16) = 3w

Then, divide both sides by 3 to get the amount for w, or water, by itself:

5 and 1/3 = w

I hope this helps! ☺

Jorge’s monthly bill from his Internet service provider was $25. The service provider charges a base rate of $15 per month plus

Hatshy [7]

Answer:

Jorge was charged for 10 hours that month

Step-by-step explanation:

Given : Jorge’s monthly bill from his Internet service provider was $25.

Also given : The service provider charges a base rate of $15 per month plus $1 for each hour that the service is used

We have to find the number of hours that Jorge was charged for that month.

Let the number of hour be x,

Total bill = base rate + 1 (number of hours used)

Total bill = base rate + 1(x)

Substitute the values, we get,

⇒ 25 = 15 + 1 (x)

Solving we get,

⇒ 25 - 15 = x

10 = x

Thus, Jorge was charged for 10 hours that month

If two standard six-sided dice are tossed, what is the probability that a 5 is rolled on at least one of the two dice? express y

zaharov [31]

We define the probability of a particular event occurring as:
$\frac{number\ of \ desired\ outcomes}{number\ of\ possible\ outcomes}$

What are the total number of possible outcomes for the rolling of two dice? The rolls - though performed at the same time - are independent, which means one roll has no effect on the other. There are six possible outcomes for the first die, and for each of those, there are six possible outcomes for the second, for a total of 6 x 6 = 36 possible rolls.

Now that we've found the number of possible outcomes, we need to find the number of desired outcomes. What are our desired outcomes in this problem? They are asking for all outcomes where there is at least one 5 rolled. It turns out, there are only 3:

(1) D1 - 5, D2 - Anything else, (2), D1 - Anything else, D2 - 5, and (3) D1 - 5, D2 - 5

So, we have $\frac{3}{36} = \frac{1}{12}$ probability of rolling at least one 5.
