there are three source of resistance in parallel circuit. Two of them are rated at 20 ohms, the other at 10 ohms. What is the circuits total resistance

Answers

Answer 1

Answer: in paraller connection you can calculate the equivlant resistqnce from the relation :
1/R(equi) = 1/R1 + 1/R2 + 1/R3
1/R(equi) = 1/20 +1/20 + 1/10
1/R(equi) = 0.05+0.05+0.1 = 0.2
so, R(equi) = 5 ohms

I am a decimalIf you double me,my double is between 0.6 and 0.7,
But closer to 0.6.

My Thousandths digit is not a 2.
But the thousandths digit of my double is.
What decimal might I be?

Answers

0.6<2x<0.65 (because it's closer to 6)
0.3<x<0.325

Since the thousandths digit of 2x is 2, then the thousandths digit of x is 1 or 6, so the decimal could be 0.301, 0.302, 0.311, 0.312, 0.321

Hope this helps :)

Numbers greater than 0.3 and less then 0.35 are between .6 and .7 when doubled.

Lets assume it is a decimal that goes up to the thousandths.
0.310 to 0.324 Would be closer to .6 than .7. We know the thousands digit has to be a 1 or a 6 because its double ends in a two. So it looks like our options are .311, .316 and .321.

hancock building dimensions. the top of the john handcock building in Chicago is a rectangle whose length is 60ft more than width. the perimeter is 520 ft. find the width and the length of the rectangle. find the area of the rectangle.

Answers

Rectangle shape.
Length = x + 60 ft
Width = x
Perimeter = 520

Perimeter = 2(L+W)
520 = 2(x+60) + 2(x)
520 = 2x + 120 + 2x
520 = 4x + 120
520 - 120 = 4x
400 = 4x
400/4 = x
100 = x

Length = x + 60 = 100 + 60 = 160 ft
Width = x = 100 ft

Area = Length * Width
A = 160ft * 100ft
A = 16,000 ft²

On an uphill hike Ted climbs at 3mph. Going back down, he runs at 5mph. If it takes him forty minutes longer to climb up than run down, then what is the length of the hike? if possible, I would like a clear equation.

Answers

Answer:

He hiked 10 miles.

Step-by-step explanation:

rate x time = distance

The distance up and the distance down are equal

3 mi/1 hr x (h hours + 2/3 hr) = 5 mi/1 hr x h hours

3h + 2 = 5h

2 = 2h

h = 1 hour

3mi/hr x 1 2/3 hr = 5 miles

5 mi/hr x 1 hr = 5 miles
