0.3•10^4 is it scientific notation why or why not?

Answers

Answer 1

No, this is not scientific notation. Scientific notation has a number multiplied by 10 to the power of something. But, that number has one digit in front of the decimal point. Since, here, there are none, this is not a number in scientific notation.

a truck that can carry no more than 6400 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 250 lb and each piano weighs 475 lb. Write and graph an inequality to show how many refrigerators and how many pianos that truck could carry . WIll 12 refridgerators and 8 pianos overload the truck? Explain.

Answers

I'm not going to do the entire question, but I'll do the first part.

For the first part, you have to set up an inequality. Use context clues, such as no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:

6400[tex] \leq[/tex]250r + 475p

where r represents the # refrigerators, and p represents the # pianos

Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.

Hope this helps! :)

Answer: 250 r+ 475p≤ 6400

12 refrigerators and 8 pianos will overload the truck.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Truck capacity: 6400 (no more than means that the weight of the products must be equal to 6400 lbs or less) Weight of one piano: 475 Weight of one refrigerator: 250

So, the inequality that represents this case is :

250 r+ 475p≤ 6400

Where:

r = number of refrigerators

p = number of pianos

For 12 refrigerators and 8 pianos we simply replace the values:

250 (12) + 475 (8) ≤ 6400

3000+3800≤ 6400

6800≤ 6400

6800 lbs will overload truck. Because 6800lbs exceeds the capacity of the truck.(6400 lb)

Sue uses the expression (8 x 3,000) + (8 x 200) + (8 x 9) to help solve a multiplication problem. What is Sue's multiplication problem?

Answers

25,672 if you take it step by step you will get it

Answer:

(I will say in the explanation)

Step-by-step explanation:

Sue's problem is (8 x 3000) + (8 x 200) + (8 x 9).

First, let's add up the broken apart numbers.

3000+200+9 = 3209

So since we got 3209 as our answer, the multiplication is about 3209! But we don't just stop here. There's a little bit more.

Now, Sue's multiplication expressions broken apart numbers keep multiplying 8! This means 8 is being multiplied by 3209!

So Sue's problem is 8 x 3,209 !

But if you want to multiply it,

3,209

x 8

25,672

This is the answer!

A store manager realizes that he has too many jeans in stock. After he finished taking inventory, he has a total of 688 jeans. He decides to reduce the stock by having a buy one get one free sale. That means that every purchase will reduce this inventory by 2 pairs of jeans.

The expression below describes this situation.

688−2x

In this expression, what does the term 2x represent?

A. the number of jeans purchased

B. the total amount of jeans in stock

C. the number of jeans the stock is reduced by from each sale

D. the number of jeans sold with each purchase

Answers

I think the answer is a
I don't know but i hope it will help

Answer:

Option C)

Step-by-step explanation:

We are given the following information in the question:

Number of jeans in inventory = 688

The store manager decides to reduce the the stock by giving a buy one get one free scheme. That means that every purchase will reduce this inventory by 2 pairs of jeans.

This can be represented with the help of equation:

[tex]688 - 2x[/tex]

where x is the number of jeans purchased.

In the above expression the term 2x is the total number of jeans sold, where x is the number of jeans sold. Due to buy one one free offer the jeans reduced from the inventory are double the jeans sold.

Thus, 2x in the equation means that every purchase will reduce the inventory by 2 pairs of jeans where x is the number of purchases.

In George’s neighborhood there are 33 cats and 33 dogs roaming free.What percent of the animals roaming free are dogs?

A.35%

B.40%

C.45%

D.50%

Answers

First, we'll figure out how many animals there are in total by adding up the cats and the dogs. In this case, we have 33+33=66 total animals. Then we need to figure out what fraction of these 66 animals are dogs:
[tex]\frac{33}{60}=\frac{1}{2}[/tex]

So half of the animals are dogs. To write that as a percent, we need the fraction to be over 100, so:
[tex]\frac{1}{2}=\frac{50}{100}[/tex]

50% of the animals are dogs.

In the last election, candidate C received 15,000 fewer votes than candidate B. If a total of 109,000 votes were cast, how many votes did candidate B receive?

Answers

Hello, so let's break this down.

There is a total of 109,000 votes all together.

If you want to find out how much candidate B received, all you need to do is subtract 15,000 from 109,000 which would be 94,000.

If you want to make sure that is correct, add candidate B's total votes from candidate C's total votes if it adds up to 209,000 (94,000+15,000 = 209,000).

Hope this helps! =)

Let x be the votes candidate B received.

x - 15,000 = 109,000
Add 15,000 to the other side
x = 124,000

Candidate B received 124,000 votes.

Hope that helped! :)

Hello,

Any line that is perpendicular to another line has a negative reciprocal of the slope. So the negative reciprocal of -2/3 is 3/2. Now with the new slope, let's pt it in the equation to find the slop-intercept equation BY using point-slope form: y-y1 = m (slope) (x-x1).

If I put the numbers in the equation, it would look like: y+8 = 3/2 (x-4). Let's simplify by distributing 3/2 to the parenthesis: y + 8 = 3/2x - 6.

To get "y" by itself, let's subtract 8 from both sides: y = 3/2x - 14.

So, the equation is now y = 3/2x - 14.

In the box you would write, "-14".
