Answer: Yes they are
Step-by-step explanation:
I believe that it would be y = (13/8)x
Answer:
36+64=100 100 to the square root is 10
Step-by-step explanation:
I'm not giving a diagram just draw a triangle and make the base of it 8 and the length of it 6 but the diagonal part 10
It's the pythagorean theorum. a^2 + b^2 = c^2
^2= to the 2nd power. or squared.
In this case it really doesnt matter which one you label for this part of math.
so 8^2 + 6^2 = C^2 where C is the shortest distance between the houses.
and 8 and 6 were the lengths given.
64+36=100
100's square root is 10 because 10^2 is 100 or 10*10 is 100. If you dont know what squaring is.
Its multiplying something by that something once so 1 squared is 1 because its 1*1 you are multiplying it once 2 squared or 2^2 is 4 because 2*2 is 4 3 squared or 3^2 is 9 because 3*3 is 9. 4 squared is 16 because 4*4 is 16. and if you did 2 to the power of 3 of 2 cubed it would be 8 because 2*2*2 is 8.
Answer:
C) 8
Step-by-step explanation:
-5(a+3)=-55
a+3=-55/-5
a+3=11
a=11-3
a=8
T = days passed
r = rate of growth
by 0 day, or t = 0, there are 2 folks sick,
by the third day, t = 3, there are 40 folks sick,
