Answer:

Agree.

Step-by-step explanation:

1. (5^r)^t can be represented simply as 5^rt.

2. when r as negative integer, t as positive integer, rt is always a negative integer

3. when ever the indices rt is negative, the number 5^rt will be less than 1, thus cannot be a whole number for sure.

Jessica has 20 pieces of candy in a bag: 2 mint sticks, 9 jelly treats, and 9 fruit tart chews. If she eats one piece every 10 m

dedylja [7]

Answer:

18.95%

Step-by-step explanation:

In this case what we must do is calculate the probability of eating a jelly treats first and then another jelly treats, being the final probability the multiplication of these events.

We know that there are 20 in total and that initially there are 9 jelly treats, so the first event is the probability:

9/20

And the second event, with one less in each, would be:

8/19

The final probability then:

9/20 * 8/19 = 0.1895

So the probability of this happening is 18.95%

Six more than the quotient of a number b and 45 is grater than 4

Wewaii [24]

$(b:45)+6>4\qquad\text{subtract 6 from both sides}\\\\\dfrac{b}{45}>-2\qquad\text{multiply both sides by 45}\\\\\boxed{b>-90}$

The quotient of two numbers is 3 and their sum is 8 what are he two numbers

Nezavi [6.7K]

<h2>Translating Word Equations into Numerical Equations</h2>

To change words into equations, we can recognize keywords that translate into operations and/or numbers:

<em>quotient</em> = divide
<em>a number/the number/two numbers</em> = variables
<em>sum</em> = add

<h2>Solving the Question</h2>

Let the two numbers be <em>a</em> and <em>b</em>.

We're given:

quotient of <em>a</em> and <em>b</em> is 3
⇒ $\dfrac{a}{b}=3$
sum of <em>a</em> and <em>b</em> is 8
⇒ $a+b=8$

First, isolate <em>a</em> in the first equation and substitute it in the second equation to solve for <em>b</em>:

$\dfrac{a}{b}=3\\\\a=3b$

$a+b=8\\3b+b=8\\4b=8\\b=2$

Therefore, one of the numbers is 2. Substitute this into one of our equations to solve for <em>a</em>:

$a+b=8\\a+2=8\\a=6$

Therefore, the other number is 6.

<h2>Answer</h2>

The two numbers are 2 and 6.

PLEASE HELP IM SO CONFUSED!!!!! I attached a photo

nadezda [96]

It would be 5^-1

Because 5^7 • 5^5 = 5^12

And dividing would be subtract so 12 - 13 = -1
