The answer is 6.4x10^-4 I know it because I took algebra in 9th grade and they show me how to work with scientific notation
Answer:

Step-by-step explanation:
slope-intercept form: y = mx + b
y = (x , y)
m = slope = 
x = (x , y)
b = y-intercept = 
With this given information, your slope will be 
It is given to us that Tatenda takes t seconds to mow a square meter of lawn and Ciara takes c seconds to mow a square meter of lawn.
It is also given to us that Tatenda mows 700 square meters of lawn per week and Ciara mows 750 square meters of lawn per week.
Thus, if Tatenda mows 700
in a week, then that means he took
seconds to complete the mowing.
Likewise, if Ciara mows 750
in a week, then that means she took
seconds to complete the mowing.
Answer:
41 inches
Step-by-step explanation:
To solve for the diagonal length of his television, we can use the formula:
a² + b² = c²
Square the length and width of the TV then add them together. Then find the square root of the sum.
40² = 1600
9² = 81
1600 + 81 = 1681
√1681 = 41
