What is this number in standard form?

attashe74 [19]

The number (7×100)+(4×1/100)+(8×1/1,000) in standard form is 7.0048 × 10²

<h3>How to write number in standard form?</h3>

The number can be represented in standard form as follows:

(7 × 100) + (4 × 1/100)+(8 × 1/1,000)

Therefore,

7 × 100 = 700 = 7 × 10²

4 × 1/100 = 4 × 10⁻²

8 × 1/1,000 = 8 × 10⁻³

Therefore,

7 × 10² + 4 × 10⁻² + 8 × 10⁻³ = 700.048 = 7.0048 × 10²

There are 24 people using a gun. the ratio of men to women is 2 : 1. how many men are using the gym

Arada [10]

The number of men using the gun is <u>8</u>, using the given ratio of men to women as 2:1.

In the question, we are given that the ratio of men to women using a gun is 2:1, and a total of 24 people use a gun.

We are asked to find the number of men using the gun.

By the given ratio, we take the number of men using a gun to be 2x, whereas the number of women using a gun is x.

Thus, the total number of people using the gun = the number of men using a gun + the number of women using the gun,

or, the total number of people using the gun = 2x + x = 3x.

But, the total number of people using the gun is given to be 24.

Thus, we get an equation 3x = 24.

On solving this, we get:

3x = 24,

or, 3x/3 = 24/3,

or, x = 8.

Now, the number of men using a gun = 2x = 2*8 = 16.

The number of women using a gun = x = 8.

Thus, the number of men using the gun is <u>8</u>, using the given ratio of men to women as 2:1.

Mrs. Elizondo runs around a 400-meter track at a constant speed of 250 meter per minute. How many minutes does it take Mrs. Eliz

anastassius [24]

Answer: See explanation

Step-by-step explanation:

From the information, we are told that Mrs. Elizondo runs around a 400-meter track. If she runs 4 laps, the total meters will be:

= 400 × 4

= 1600 meters

Since she uses a constant speed of 250 meter per minute. The number if minutes taken to complete the 4 laps will be gotten by dividing 1600 by 250. This will be:

= 1600 / 250

= 6.4 minutes

= 6 minutes + (0.4 × 60 seconds).

= 6 minutes 24 seconds
