Answer:
24 cm.
Step-by-step explanation:
If you take 6 cm. and multiply it by 4(magnify it), you get 6 x 4, which is 24.
Hope this helps!
The answer is a = -4 and b = 0.
We can solve this by looking at a system of equations using what was given
a + b = -4
a - b = -4
Then add then two equations together.
2a = -8 ---> then divide by 2 for your a value
a = -4
You can then put that into the equation and solve for b.
-4 + b = -4 ---> add 4 to both sides
b = 0
The equation of the line is
4b + a = 0
The slope of the line is
m = -1/4
With a rise of 1 and run of -4 which corresponds to a hypotenuse of
√(4² + (-1)²) = √17
Therefore, the sine of the angle is
sin θ = 1/√17<span />
Set up a proportion:
5/200 = 7/x
Cross multiply:
200 * 7 = 5 * x
1400 = 5x
Divide 5 to both sides:
x = 280
Answer: $14.4
Step-by-step explanation:
To calculate the tip, you need to multiply the bill times .2. So 72x .2 = 14.4
