Answer:

370000000=3.70000000\cdot10^8=3.7\cdot 10^8 \\ 7600=7.600\cdot 10^3

Step-by-step explanation:

Both numbers are integers (not fractions)

if you write an integer in scientific notation:

1) inset a comma between first and second digit (3.70000000)

2) calculate all digits on the right side of insetting comma (there are 8 digits after a comma: 7,0,0,0,0,0,0,0)

3) a fraction from point 1) you multiply by 10 to the power, which is equal to a number of digits after comma (8)

4) according this tips, you have 3.70000000\cdot 10^8

5) for a better notation, you may remove ending zeros

3.7\cdot 10^8

Data:
Apples = 28
Oranges = 20
Pears = 12

<span>What is the ratio of apples to the total pieces of fruit?
Solving:
</span>\frac{apples}{apples+oranges+pears} =  \frac{28}{28+20+12} =  \frac{28}{60} \frac{\div4}{\div4} \to\:\boxed{\boxed{ratio = \frac{7}{15}}}\end{array}}\qquad\quad\checkmark<span>

I need to find the slope-intercept form of this problem in the picture, please I need help!
dsp73
Take two points
(-3, -1) and (1,2)
Find slope
slope formula: m = y2 - y1 / x2 - x1
m = 2 - (-1) / 1 - (-3) = 2 + 1 / 1 + 3 = 3/4
Substitute one of the points into slope intercept form (y =mx + b) to find the y intercept.

y= mx + b
2 = 3/4(1) + b
2 = 3/4 + b
1.25 = b

So:
y = 3/4x + 1.25
