Write 29,678,900,522 in scientific notation!!!!

1 answer:

4 0

The goal of writing a number in scientific notation is to have a decimal number, with one digit to the left of the decimal point, followed by a × 10 to some power.To format your number in this way, we'll divide the 2967890052 by 10, 9 time(s), making it a 2.96789.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 109 next to the 2.96789.So, the final answer is 2.96789 × 109

The linear equation y=-2x+4 is represented on the graph below. A second linear equation is represented by the data in the table.

atroni [7]

Answer:

The solution of the system of equations is (2,0)

Step-by-step explanation:

step 1

Find the equation of the second line

we have

y=-2x+4 ----> First equation

Find the second linear equation

we have

(-4,-3), (0,-1),(2,0),(6,2)

Find the slope m

Points (0,-1),(2,0) ---> y-intercept and x-intercept of the second equation

m=(0+1)/(2-0)

m=1/2

The equation of the line into slope intercept form is equal to

y=(1/2)x-1

step 2

Solve the system of equations

we have

y=-2x+4 ----> First equation

y=(1/2)x-1 ----> Second equation

Solve by graphing

The intersection point is (2,0)

therefore

The solution of the system of equations is (2,0)

see the attached figure

Describe how to round 678 to the nearest hundred.

Vika [28.1K]

The nearest hundred will be in the hundredth place

For example, 2000

2 is in the thousands, followed by hundreds, ten, ones

to round to the nearest hundreds, you must look at the tens place (in this case 7) IF it is 5 or higher round the hundreds 1 number higher (+1) If it is 4 or lower, round all of the numbers including the number you are looking at to zero without changing the one in front of it.

So in this case 678 will equal 700

Example: if it were 644, then it would be 600

hope this helps
