Answer 1
Answer: 50 minus 30 is 20.
You could subtract 20 from 50 to see what you would get, and then just plug it in to double check.

Answer:

2.700 × 10-7

Step-by-step explanation:

Answer:  2.7*10^-4

step by step explanation:

1. Make the number a new number between 1 and 10

More Icon

Move the decimal point to make 0.00027 a new number between 1 and 10. Because our original number is less than one, we move the decimal point to the right. Drop any zeroes in front of the number. Keep track of how many times we move the decimal point.

0.00027 -> 2.7

Our new number is 2.7. We moved the decimal point 4 times.

2. Define the power of 10

More Icon

Because our original number was less than one, the exponent defining the power of 10 is negative. Remember, we moved the decimal point 4 times, so the exponent is negative 4

10^(-4)

3. Final result

2.7*10^(-4)

Which two numbers both round to 1,500 when rounded to the nearest hundred?

Answers

The two numbers where  both round to 1,500 when rounded to the nearest hundred is option c. 1457 and 1547.

What is Rounded number?

The rounded number should be that where the number should be rounded to the nearest tenth, hundred or thousand

Since the number is 1500

So for hundred the number should be likely 1457 and 1547.

hence, the option c is correct.

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.Work out the total amount of money in the account at the end of 3 years.
Give your answer to the nearest rupee.

Answers

Answer:

There will be 20 914 rupees in the amount at the end of 3 years.

Step-by-step explanation:

The amount of rupes after t years in compound interest is given by:

A(t) = A(0)(1+r)^(t)

In which A(0) is the initial amount and r is the interest rate, as a decimal.

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.

This means that A(0) = 20000, r = 0.015. So

A(t) = A(0)(1+r)^(t)

A(t) = 20000(1+0.015)^(t)

A(t) = 20000(1.015)^(t)

Work out the total amount of money in the account at the end of 3 years.

This is A(3). So

A(3) = 20000(1.015)^(3) = 20913.6

Rounding to the nearest rupee.

There will be 20 914 rupees in the amount at the end of 3 years.

Final answer:

Hiran invested 20 000 rupees at 1.5% compound interest for 3 years. By applying the formula for compound interest, the total amount in the account at the end of 3 years would be approximately 20747 rupees.

Explanation:

The subject of this question is compound interest. The formula for calculating compound interest is A = P(1+ r/n)^(nt), where 'A' is the amount of money accumulated after n years, including interest. 'P' is the principal amount (the initial amount of money), 'r' is the annual interest rate (in decimal), 'n' is the number of times that interest is compounded per year, and 't' is the time the money is invested for in years.

In the given problem, Hiran has invested a principal amount of 20 000 rupees for 3 years at an annual interest rate of 1.5%. So, here P=20 000, r=1.5/100=0.015 (since 1.5% = 1.5/100 = 0.015), n=1 (since it is annually), and t=3.

By substituting these values into the formula, we get A = 20 000(1+ 0.015/1)^(1*3) which results in approximately 20747 rupees. This denotes the total amount in the account at the end of 3 years.

You buy 1.95 pounds of oranges and 1.65 pounds of apples. Oranges and apples sell for the same price per pound. The total​ cost, after using a 75¢​-off ​coupon, is ​$2.49. If c represents the cost of the fruit in dollars per​ pound, what equation could you use to find the value of​ c?

Answers

Answer:

  (1.95 +1.65)c -0.75 = 2.49

Step-by-step explanation:

The cost of the fruit is the cost per pound (c) multiplied by the number of pounds, 1.95 +1.65. After $0.75 is deducted, the total cost is $2.49. The equation that says this is ...

  (1.95 +1.65)c -0.75 = 2.49

__

  3.6c = 3.24 . . . . add 0.75, simplify

  c = 0.9 . . . . . . divide by the coefficient of c

The cost of the fruit is $0.90 per pound.

Find the value of a. Then find the angle measures of the quadrilateral.

Answers

Answer:

a = 60

Step-by-step explanation:

Since it is a quadrilateral, the sum of interior angles is equal to 360°. Now you have to create an equation to solve this question. To create an equation, you have to add all the interior angles to 360°.

The equation would be 2a°+a°+a°+2a° = 360°.

Then you would simplify it to 6a° = 360.

You would divide 6 on both sides to get to a° = 60.

Therefore, the value of a is 60.
