Answer:
<em>15 people</em>
Step-by-step explanation:
since Raul and his friends each weigh 1/20 ton,
and the total weight reads 3/4 ton
The total number pf people on the scale will be:
<em>The total weight of Raul and his friends divided by their individual weight</em>
==> (3/4 ton) ÷ (1/20 ton)
= 3/4 X 20/1 = <em>15 people</em>
Answer:
x² + 4x + 3
Step-by-step explanation:
to find f(g(x)), substitute x = g(x) into f(x)
f(g(x)) = f(x + 2) = (x + 2)² - 1 = x² + 4x + 4 - 1 = x² + 4x + 3
Actually, that is a trick question. Matt is correct because 24/4 is equal to 6. 1/4 is equal to 0.25. Add them together and you get 6.25. I just split 25/4 into 24/4 and 1/4 if you didn't understand what I did.
Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40
Answer:
y = -4/36 * (x-6)^2 + 4
Step-by-step explanation:
The quadratic equation expressed in vertex from is
y = a(x-h)^2 + k
The vertex is
Vertex = (h,k) = (6,4)
This means
y = a(x-6)^2 + 4
To find a, we know that at 12 feet from the water jet, the height is equal to zero.
0 = a(12-6)^2 + 4
a = -4/36
Therefore, the equation is
y = -4/36 * (x-6)^2 + 4
Please see attached graph for reference.
