9/16
Step-by-step explanation:
Next time write the mixed number like this:
1 1/3 just so you know so ppl can answer it better
Q=x/5-4
let me know if you have any questions
Answer:
Pythagorean Theorem: c2 = a2 + b2
Find the area by adding the areas of the three triangles. The area of a right triangle is: A = ½bh
Two triangles are identical so you can just multiply the area of the first triangle by two: 2A1 = 2(½bh) = 2(½ab) = ab.
The total area of the trapezoid is : A1 + A2 = ab + ½c2
You multiply both sides by 2 to get rid of the ½: (a2 + 2ab + b2) = 2ab + c2
You subtract out the 2ab: a2 + b2 = c2.
Then what is left is the proof: a2 + b2 = c2
x = hours
car 1 left an hour before car 2 so you have 55(x+1)
car 2 = 75x
add them together to equal miles driven:
55(x+1) + 75x = 380
55x+55 + 75x = 380
combine like terms:
130x+55 = 380
subtract 55 from each side:
130x = 325
divide both sides by 130
x = 325 /130 = 2.5
x = 2.5 hours
so 2.5 hours
Answer:
(x+5)² + (y+6)² = 9
Step-by-step explanation:
the equation of a circle is
(x-a)² + (y-b)² = r²
with (a,b) being the center coordinates and r being the radius (half the diameter).
so, in our case here a = -5, b = -6
and r is the distance from the center to any point of the circle. that includes the lowest point asking the edge.
the distance of (-5,-6) to (-5,-9) is 3, as both points have the same x-value, and the only difference is in the y-value.
as we are talking about a distance, negative values don't make sense. so, we need the absolute value of -9 - -6 or then of -3, and that is 3.
