How long will it take an airplane flying at an average cruising speed of 230 miles per hour to fly 1380 miles?

1 answer:

7 0

Since it takes one hour to fly 230 miles, and we are looking for the number of hours, we can divide the number of miles we are given by the speed. In this case, we would divide 1380 by 230 to get 6. This means it would take 6 hours for the plane to fly 1380 miles.

serious [3.7K]

Answer:

The maximum deposit is $4,000 billion.

Step-by-step explanation:

Consider the provided information.

It is given that the required reserve ratio of 10 percent for all banks.

It is given that total bank reserves of $400 billion.

Let the maximum deposit is x.

Therefore, 10% of x = $400 billion

$\frac{10}{100}\times x=\$400\text{ billion}$

$x=\frac{100}{10}\times \$400\text{ billion}$

$x=10\times \$400\text{ billion}$

$x=\$4000\text{ billion}$

Hence, the maximum deposit is $4,000 billion.

4x+2y=10 <br> X-y=13 <br> Write in (x,y)

Bad White [126]

Answer:

(x = 6, y = -7)

Step-by-step explanation:

Solve the following system:

{4 x + 2 y = 10 | (equation 1)

x - y = 13 | (equation 2)

Subtract 1/4 × (equation 1) from equation 2:

{4 x + 2 y = 10 | (equation 1)

0 x - (3 y)/2 = 21/2 | (equation 2)

Divide equation 1 by 2:

{2 x + y = 5 | (equation 1)

0 x - (3 y)/2 = 21/2 | (equation 2)

Multiply equation 2 by 2/3:

{2 x + y = 5 | (equation 1)

0 x - y = 7 | (equation 2)

Multiply equation 2 by -1:

{2 x + y = 5 | (equation 1)

0 x+y = -7 | (equation 2)

Subtract equation 2 from equation 1:

{2 x+0 y = 12 | (equation 1)

0 x+y = -7 | (equation 2)

Divide equation 1 by 2:

{x+0 y = 6 | (equation 1)

0 x+y = -7 | (equation 2)

Collect results:

Answer: {x = 6 , y = -7

Write a problem that requires multiplying two decimals to find the answer. The product must have two decimals places.

julsineya [31]

Answer:

3.5 * 6.7 = 23.45

Step-by-step explanation:

(I am assuming you know how to do 2-digit by 2-digit problem, but just in case you don't I am putting in how to do it.)

You would multiply the problem like a normal 2-digit by 2-digit problem.

- multiply the ones places (5*7=35)

- you bring the 3 of the 35 and put it above the other 3

- you then do 7*3=21+3 because you moved it.

-so the first part of the question would be 35*7=245

-you go below the 5 and put a zero because you dont need the ones place anymore.

-you then do the same thing but with the tens place instead.

- You would then get 35*6=210, but you can't forget the zero.

- you would then add 245+2100=2,345

- But don't forget the decimals. you have to add the decimals to the answer.

- you count how many numbers that are behing both numbers, in this case it would be two.

- you then put the decimal after the ones and tens place.
