Answer:
8
Step-by-step explanation:
Constant of proportionality, k = y/x
y = earnings ($)
x = time (h)
Any point on the line can be used to determine the constant of proportionality. Let's use, (1, 8)
Constant of proportionality, k = y/x = 8/1
k = 8
The answer is d, the other zero is rational, because if you factor a quadratic equation with rational numbers, and that produces at least one rational zero, you know that the other zero has to be rational. The x with the power of two tells you that there are two zeros, which both must be rational since one is already rational.
Answer:
ob = 6 bc = 11
Step-by-step explanation:
all sides are equal in rhombus so bc = 11
diagonals bisect each other at right angle.
so ob= do = 6
Answer:
The Susana swam the fastest.
Step-by-step explanation:
<u>Speed</u> : It is defined as the distance traveled per unit time.
<u>Formula used</u> :
First we have to determine speed of the following persons.
<u>For Tawni :</u>
Distance = 50 m
Time = 40.8 s
1.225 m/s which is the speed of Tawni.
--
<u>For Pepita :</u>
Distance = 100 m
Time = 60.2 s
1.661 m/s which is the speed of Pepita
--
<u>For Susana :</u>
Distance = 200 m
Time = 112.4 s
1.779 m/s which is the speed of Susana
From this we conclude that, in this problem meter affects the response and the speed of Susana is more than the Pepita and Tawani.
Thus, Susana swam the fastest.
No because it has to be a even number to be divisible by 2 and same goes with 5 something has to x the 2 with the number like 2/4=2 because 2x2 is 4
