Answer:
-10
Step-by-step explanation:
solve algebraically.
-2=(2+x)/4
*4 *4
-8=2+x
-2 -2
-10=x
Answer:
joint variation means L (safe load) is directly proportional to both w and d2
inverse proportionality means L = k/l
So the equation is:
L = k(wd2/l)
You are given:
w = 6 in
d = 5 in
l = 12 ft
L = 7666 lbs
7666 = k(6*52/12)
Solve for the constant, k.
7666 = k (6*25/12)
7666 = k (150/12)
7666 = k (12.5)
613.28 lbs/(ft.in3) = k
Use this k-value to solve for L in the last part of the question.
What safe load, L would a beam 3 in. wide, 7 in. deep and 15 ft long of the same material support? (Round off your answer to the nearest pound.)
w = 3 in
d =7 in
l = 15 ft
k = 613.28 lbs/(ft.in3)
Final Safe load = 6010.144 lbs *** Edited for clarity and to fix a multiplication erro
We know that 1 gallon= 4 quarts
therefore, 14 gallons=56 quarts
so
14gallons/s=56 qt/s
if we would need to find just gallons/second in quarts /second the answer will be simple, but we need to find the answer in qt/min
is there are 56 qt per second, it means that it will be
56*60 in 1 minute
56*60=3360
final answer
14 gallons/s=3360 qt/min
b) you could choose :
red, black
black, red
red, red
c) p(black, red) = (6/18)(12/17) = 72/306 = 4/17
There is no such word as quationbra and I feel like you either spelled it wrong or you got an unreal word.
