Estimates show that there are 1.4 * 10^8 pet fish and 9.4 * 10^6 pet reptiles in the United States. How many are there total in the United States? express in scientific notation.

Answers

Answer 1

Answer:

There are total of $2.34*10^(8)$ pet fish and reptiles in the United States.

Define the term expression?

Calculations that include changeable altering multipliers, joining, removal, and random subdivision must be done. They could accomplish the following if they united: An algorithm, some data, and a mathematical problem.

To find the total number of pet fish and reptiles in the United States, we simply need to add the number of pet fish and pet reptiles together:

Total = $1.4*10^(8) + 9.4*10^(6)$

To add these numbers together, we need to express them using the same power of 10. We can do this by rewriting 9.4 * 10^6 as 0.94 * 10^7:

Total = $1.4*10^(8) + 0.94*10^(7)$

Now, we can add the numbers together:

Total = $1.4*10^(8) + 0.94*10^(7)$

= $1.4 * 10^8 + 0.94 * 10^8$ (since $10^7 = 10 * 10^6 = 10^1 * 10^6 = 10^7$ )

= $2.34 * 10^8$

Therefore, there are a total of $2.34 * 10^8$ pet fish and reptiles in the United States.

Answer 2

Answer:

Therefore , the solution of the given problem of expressions comes out to be the total number of pet fish and reptiles in the US is roughly

1.494 * 10⁸.

What precisely is an expression?

It is necessary to perform calculations which it involve joining, removal, and random subdivision variable changing multipliers. If they banded together, they could do the following: A mathematical challenge, some information, and an algorithm. A statement of equation truth contains formulas, elements, and arithmetic procedures like additions, subtractions, errors, and groupings. It is possible to assess and analyse words and phrases.

Here,

The number of fish and reptiles kept as pets must be added to the overall number of pets:

=> 1.4 * 10⁸ + 9.4 * 10⁶

We must change these numbers to the same power of 10 in order to add them. Since 108 is equal to 100 million,

we can achieve this by moving the decimal point in the second figure two places to the right:

=> 1.4 * 10⁸ + 0.094 * 10⁸

We can now multiply the numbers:

=> 1.494 * 10⁸

Thus, the total number of pet fish and reptiles in the US is roughly

=> 1.494 * 10⁸.

Tia cut 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces.How much longer is one of Martha's wires than one of Tina's?

Answers

19.2 centimeters

Explanation: Convert 4m 8cm into cm so it is 408cm. Divide 408 by 10 and you get 40.8cm. Then divide 540 by 9 and you get 60cm. 40.8 and 60 are the measurements of each piece of wire. Subtract 40.8cm from 60cm to get 19.2cm which is the answer.

If your state has a property tax rate of 0.056, and you pay $3,164.45 in property taxes every year, what is the assessed value of your property?a. $177,209
b. $21,265
c. $56,508
d. $48,684

Answers

The assessed value of your property is $56,508.

Given that, the rate of property tax=0.056 and tax money=$3,164.45.

What is a tax?

Money that the government collects is based on income, sales, and other activities.

Let the assessed value of your property is x.

Now, 0.056×x=3,164.45

⇒x=3,164.45/0.056

⇒x=56,508.035≈56,508

Therefore, the assessed value of your property is $56,508.

Fred works for $8.75 per hour. His regular hours are 40 hours per week and he gets time and a half for overtime. One week he works 47.5 hours. He wants to calculate his pay.

Answers

For the first 40 hours, he gets 8.75/hour, so 40*8.75 = 350. For the last 7.5 hours, he gets (8.75*1.5)/hour. 8.75*1.5 = 13.125/hour, or 13.13/hour. Then do 13.13/hour * 7.5 hours = 98.48. Now add together 350 and 98.48. That equals $448.48 total for the week

Answer:

350, 13.13/hour, 98.48, 448.48.
