Answer:
A
Step-by-step explanation:
Rational numbers have an ending decimal expansion. If you put the other numbers into a calculator you will se that there is just more numbers after the decimal point
B i think
(sorry if it’s wrong)
Answer:
B. 745 miles
Step-by-step explanation:
Given that
Kim took 3000 miles trip in 4 days
And,
1st day - 850 miles
2nd day - 745 miles
3rd day - 660 miles
We need to find out that how much she travel in the 4th day
So, it is
= 3000 miles - 850 miles - 745 miles - 660 miles
= 745 miles
Hence, the option b is correct
Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
On the graph, the point on the y-axis is the y-intercept. That point is (0, -1). So the y-intercept is -1.
To find the slope, find two points and put it in the slope equation.
Point A: (0, -1)
Point B: (-1, 0)
m = 
Point A: 
Point B: 
m = 
m = 
m = -1
y = -1x - 1
In other words, y = -x - 1

To determine the extent of how many times greater is the number of bacteria in petri dish A than petri dish B, we simply have to take the ratio of the two.
1.75 x 10^18 / 6.25 x 10^15 = 280
So the bacteria in petri dish A is 280 times larger.
In scientific notation:
2.8 x 10^2
Hope this helps :)
