So here we use the pythagorean theorem which is a2 + b2 = c2 (“a” squared times “b” squared equals “c” squared) the length from calvins house to the intersection is “a” and the length from phoebes house to the intersection is “b” so in order to find out the length of “c” (calvins house to phoebes house) we need to use the pythagorean theorem
a2 275x275=75,625
b2 113x113 = 12,769
so now that we have figured out what a2 and b2 are let’s add them
75,625 + 12,769 = 88,394
now since we only need to find out the length and not the area we need to find the square root of 88,394
the square root of 88,394 is 297.311 (i cut off the decimal after three places)
the direct length from phoebes house to calvins is 297.311 meters
Answer:
e^x graph
Step-by-step explanation:
Answer:
a, y =3/x
x = 0.5 => y = 3/0.5 = 6
x = 1 => y = 3/1 = 3
x = 2 => y = 3/2 = 1.5
x = 3 => y = 3/3 = 1
x = 4 => y = 3/4 = 0.75
b,
y = 3/x passes (0.5, 6) => A is correct
Hope this helps!
I got three numbers ...
798, 1726, & 2654
liters is the amount to be drained out and replaced
<em><u>Solution:</u></em>
40 % antifreeze solution in 16 liter radiator
Let "x" be the amount drained from radiation and replaced with pure antifreeze
To obtain a 60 % antifreeze solution
The original solution is 16 liter, 40% of which is antifreeze
You want the solution to be 60% antifreeze:
60 % x 16 =
You will remove x liters of the 40% solution and replace it with x liters pure (100%) antifreeze.
Let us solve expression for "x"
Thus liters is the amount to be drained out and replaced
