Answer:
5
Step-by-step explanation:
10% of 50 is equal to 5.
50 ÷ 10 = 5
We can do this easily using 0s.
(x - i) (x + i) (x + 4) (x - 1) = 0
If you plug in any of the numbers, you'll get 0, making the equation true.
Answer:
Step-by-step explanation:
We are given that Chantal drives at a constant speed of 55 miles per hour.
If, d represents the total distance in miles, and
h represents number of hours, the following equation can be used to express the given situation:
For every hour, a distance of 55 miles is covered.
Thus, if h = 1,
If h = 2, .
Therefore, , is an ideal equation that represents the situation given in the question above.
Answer:
A
Step-by-step explanation:
You are given the table
This table represents a linear relationship between time and water leaked, because
The linear function has the equation
Find m and b:
So,
Find the x-intercept:
Hence, point (7,0) is x-intercept with the meaning x=7 is the time it takes to empty the water in the pool
Answer:
10cmsquare
Step-by-step explanation:
name the triangle ABC
use pythagoras theo.
ACsq=ABsq+BCsq
ACsq=5×5 + 4×4
ACsq=25+16
ACsq=41
AC=sq root 41
ar shaded region=(use pythagoras again with the shaded triangle)
root of 41×root of 41-4×4
=41-16
=25
root of 25=5cm
