The slope of the line is (3,6)
Answer:
-0.7
Step-by-step explanation:
Given x - y = 0.7
We will assign x and y random values that has a difference of 0.7
x = 1.3
y = 0.6
Using these 2 values,
y-x = 0.6-1.3
= -0.7
As you can see here , you will get a reversed value when you reverse the expression.
Answer:
Step-by-step explanation:
Given
--- The radius of each
Required
The area between them
See attachment for illustration of the question. (figure 1)
First, calculate the height of the equilateral triangle formed by the 3 radii (See figure 2)
Using Pythagoras theorem, we have:
Collect like terms
Take square roots
Expand
Split
Now, the area of the equilateral triangle can be calculated using:
Where
Next, is to calculate the area of the sector formed by 2 radii in each circle (figure 3).
Since the radii formed an equilateral triangle, then the central angle will be 60. So:
For the three circles, the area is:
Subtract the areas of the sectors (A2) from the area of the equilateral triangle (A1), to get the area between them.
Approximate
-20 and 3
sum is -20+3=-17
multipling is -20*3=-60
Answer:
18 hours
Step-by-step explanation:
How many times does 15 go into 45?
45/15=3
To find the equal amount of time, multiply 6 hours by 3.
45 centimeters-18 hours
Hope this helps!
