Answer:

1)

Scientific: 3*10^2

Standard: 300

2)

Scientific: 4.5*10^5

Standard: 450000

3)

Scientific: 1.5*10^-3

Standard: 0.0015

Step-by-step explanation:

There is a rule in mathematics that goes like this: If you have an exponent divided by an exponent and they have the same base, it is the same thing as subtracting it from each other.  

Example: if we had [tex]\frac{10^5}{10^3}[/tex], we could subtract 3 from 5 and get 2, and therefore our answer would be 10^2.  

We can apply this rule to all three of these problems.  

1) If we subtract the exponents, we get 9-7=2. Therefore our new exponent will be 2.  Next, divide the two numbers multiplying 10.  They are nine and three. 9/3 is 3, so our answer is 3*10^2.  Next we convert to standard form.  Multiply 3 time 10^2, and you get your answer.  10^2 is 100, 3*100 is 300, so our answer in standard form would be 300.  

You can repeat this same process with all of the problems.  

A bag contains 3 red, 2 blue, 5 yellow, and 2 green marbles. What is the probability of choosing a red marble and then a blue marble

A. 5/23
B. 1/22
C. 5/21
D. 1/24

Answers

Answer: D. 1/24

Step-by-step explanation:

3+2+5+2=12 marbles total

Probability of choosing red marble is 3/12 and probability of choosing blue marble is 2/12

Multiply 3/12 * 2/12 = 6/144

Simplify to get 1/24 by dividing too and bottom by 6.

Answer:

Hello! answer: 13

Hope that helps!

Answer:

x = 13

Step-by-step explanation:

You should note that any straight angle like those = 180° where they provided supplementary angles where the sum = 180°

(11x - 15) + (5x - 13) = 180°

Combine like terms:

16x - 28 = 180°

Add 28 on both sides:

16x = 208

Divide 16 on both sides:

x = 13

Given that a function, f(x), has a domain of 7 ≤ x ≤ 60 and a range of -4 ≤ f(x) ≤ 15 and that f(8) = -2 and f(50) = 15, select the statement that could be true for f(x).

WILL GIVE 69 POINTS AND BRAINILIEST

Answers

Answer:

A

Step-by-step explanation:

The correct answer for the given function is B. f(50)=12.

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Statement A is incorrect because it gives a specific value for f(10) which is outside the given domain of the function.

Statement B Since we are given that f(50) = 15, we know that 15 is in the range of f(x). The only statement that could be true for f(x) based on the given range is B. f(50)=12.

Statement C is incorrect because it gives a specific value for f(12) which is outside the given range of the function.

Statement D is incorrect because it gives a specific value for f(5) which is outside the given domain of the function.

Arthur brought $32 to the carnival. He bought a hotdog, a t-shirt, and a ticket. The hotdog was 1/2 as much as the t-shirt. The t-shirt was 1/2 the cost of the ticket. Arthur had $2.25 leftover. What is the cost of each of the 3 things?

Answers

Answer:

$8.50,$17,32

Step-by-step explanation:

Answer:

Hotdog: $4.25

T-shirt: $8.50

Ticket: $17

Step-by-step explanation:

It finally let me post as an answer :)

If we call the price of a hotdog x, the cost of a t-shirt is 2x, because 1/2 of 2x is x, right?

So a hotdog is x, a t-shirt is 2x, and a ticket is twice that again, so 4x.

x + 2x + 4x + 2.25 = 32

He bought a hot dog, a t-shirt, and a ticket, had 2.25 left over, with a total of $32

x + 2x + 4x + 2.25 = 32

subtract 2.25 from both sides, combine like terms:

7x = 29.75

divide both sides by 7,

x = 4.25

hotdog = 4.25

T-shirt is 2x, so $8.50

ticket is 4x, so $17

4.25 + 8.50 + 17 + 2.25 = 32
