Answer:
r = 64
Step-by-step explanation:
r = (k*t*u)/s
Where,
k = constant of proportionality
t = -12,
u= -7,
s= -4,
r= -126.
r = (k*t*u)/s
-126 = (k*-12*-7)/-4
-126 * -4 = 84k
504 = 84k
k = 504/84
k = 6
Find r when t= -8, u= 8, and s= -6.
r = (k*t*u)/s
= (6*-8*8) / -6
= -384 / -6
= 64
r = 64
Answer:
There are 462.25 parts being made per hour
Step-by-step explanation:
<u>Step 1: Make an equation</u>
An automobile factory, 1849 parts are made in 4 hours.
<em>1849 / 4 = x</em>
<em />
<u>Step 2: Solve</u>
1849 / 4 = x
<em>462.25 = x</em>
<em />
Answer: There are 462.25 parts being made per hour
5x-50= 30-15x
20x= 80
x= 4 is the solution to this problem
Find the distance between points A-2; 3, B2; 1:
d = √<span>(<span>xb</span> - <span>xa</span>)2 + (<span>yb</span> - <span>ya</span>)2</span> =
= √<span>(2 - (-2))2 + (1 - 3)2</span> =
= √<span>42 + (-2)2</span> = √16 + 4 =
