Answer:

3.712 x 10^8

Step-by-step explanation:

use the commutative property to reorder the terms

(5.8x 6.4) x (10^5 x 10^2)

multiply 5.8 x 6.4 = 37.12

add 5+2=8

37.12 x 10^7

write the number in scientific notation

3.712 x 10^8

that'sur answer

Answer: 5.8 x 10^5 =

6.4 x 10^2 =

Step-by-step explanation:

There is 5 10's because number of exponents are 5

so you multiply 5.8 by 10 10 10 10 10

The other is 6.4

multiply that by 10 10

But you can't multiply by all of that with one constant

So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000

the other is 100

So now you multiply 5.8 by 100000

And multiply 6.4 by 100

A car can travel 400 miles on a full tank of petrol. A more efficient car can travel 30% further. How many miles further can it

xxTIMURxx [149]

Answer:160 miles

Explanation:

You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.

If you set out the steps with short sentences it will be clearer.

On 15 gallons, a car can travel 400 miles÷15↓

On 1 gallon, a car can travel 400÷15=262

miles

Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.

On 6 gallons the car can travel

miles.

(6 times further than on 1 gallon)

160

miles

Please explain how you find the slope of a graph? Please explain with photos.

☁️ Answer ☁️

Here's what I found:

Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).

Input the values into the formula. This gives us (10 - 8)/(-2 - 3).

Subtract the values in parentheses to get 2/(-5).

Simplify the fraction to get the slope of -2/5.

Check your result using the slope calculator.

To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
