Additive inverse; you can't just take -4.4 and make it positive.
Answer:
9 p 4 s
Step-by-step explanation:
That's the answer.
Answer:
Step-by-step explanation:
If the smallest number is 'x', then the other number = x +1
x*(x+1)= 420
Use distributive property
x*x + x*1 = 420
x² + x - 420 =0 ------> this is the required quadratic equation.

Plus every fraction you will get 7/8
And the question says about the ribbons he will get at 3/4 miles
so let the whole road is 1
so, according to the equation ; (1-7/8) = 1/8
and (1-1/4) = 3/4
so the answer is green and blue

First calculate distance traveled after 6 min.
400 * (6/60) = 400*(1/10) = 40 km
Next, draw triangle with 2 sides being 45 and 40. The included angle between these sides is 15, the angle of elevation. The third side is distance from plane to storm cloud.
Next, use Law of cosines to find distance.
d = sqrt(40^2 + 45^2 - 2(40)(45)cos(15))
d = 12.152 km
