the browns boarded a train at 3.55pm. to go home from the fair. it tookthem 25minutes to get to the station from the fair . they spent 1 hour and 15 minutes at the fair. what time did they arrive at the fair

Answers

Answer 1

Answer: Just add 25 minutes. That's because they boarded at 3:55 and took 25 minutes to just go to the fair. So in 25 more minutes they got to the fair! so it would be 4:20 when they got to the fair.

Answer 2

Answer: Do:

3.55 - 0.25 - 1.15 = 2.15 hs

They arrived at fair the 2.15 hs

4.20% of 140 is what number? A) 280. B) 120. C) 28. D) 12

Answers

All the solutions are,

1) 350 is 70% of number 500.

2) 37.5% of 64 is 24.

3) 40% of 6.5 is 2.60.

4) 20% of 140 is 28.

Now, We can simplify all the equation as,

1) Let us assume that a number = x

Hence, We get;

350 = 70% of x

Solve for x,

350 = 70x/100

350 = 7x/10

3500 = 7x

7x = 3500

x = 500

So, 350 is 70% of number 500.

2) Let us assume that, x% of 64 is 24.

Hence, We get;

⇒ x% of 64 = 24

Solve for x;

⇒ x/100 × 64 = 24

⇒ 64x = 2400

⇒ x = 2400 / 64

⇒ x = 37.5%

Hence, 37.5% of 64 is 24.

3) Let us assume that, x% of 6.5 is 2.60

Hence, We get;

x% of 6.5 = 2.6

x/100 x 6.5 = 2.6

6.5x = 260

x = 260/6.5

x = 40

Hence, 40% of 6.5 is 2.60.

4) Let us assume that a number = x

Hence, We get;

20% of 140 = x

20/100 x 140 = x

2800 = 100x

x = 2800 / 100

x = 28

Hence, 20% of 140 is 28.

The first time I did it, I got an answer that's not one of the choices. The second time
I did it, I got an answer that IS . Here are both of my procedures. If all you want is
the answer, look down below at the second one. But if you could help me out, now
that you know how to do this stuff, please look at my first solution and tell me where
I messed up. I can't find it.
=======================================================

Here's what the problem tells you:

D = 10 log ( ' I ' / 10⁻¹² )

D = 60 . . . . . find ' I ' .

Here we go:

60 = 10 log ( ' I ' / 10⁻¹² )

Divide each side by 10 :

6 = log ( ' I ' / 10⁻¹² )

Raise 10 to the power of each side of the equation:

10⁶ = ' I ' / 10⁻¹²

Multiply each side by 10¹² :

10¹⁸ = ' I '     That's 10^18. It looks bad, because that isn't one of the choices.

Let's try a slightly different procedure:

============================================

After substituting 10⁺¹² for I₀ , we're working with this formula:

   D = 10 log ( 'I' / 10⁺¹² )

Let's just look at the log part of that.

The log of a fraction is [ log(numerator) - log(denominator) ]

log of this fraction is [ log( 'I' ) - log(10⁻¹²) ]

But log(10⁻¹²) is just (-12) .

So the log of the fraction is [ log( 'I' ) + 12 ]

And the whole formula is now:

   D = 10 [ log( 'I' ) + 12 ]

60 = 10 [ log( 'I' ) + 12 ]

Divide each side by 10 :

6 = log( 'I' ) + 12

Subtract 12 from each side :

-6 = log ( ' I ' )

' I ' = 10⁻⁶

That's choice-'B' .

==================================================

I'm going to leave the first solution up there, in hopes that you, or one

If the coordinates of point P are (0,8) and the coordinates of point Q are ( 4,2), Which of the following points represents the midpoint of PQ ?a) (0,2), b) (2,4), c) (2,5), d) (4,8), e) (4,10)

Answers

The coordinates of the midpoint are just the average of the endpoint coordinates ...
x-mid is the average of the end-x's, and y-mid is the average of the end-y's.

P. x = 0, y = 8
Q. x = 4, y = 2

'x' of the midpoint is the average of 0 and 4 = (1/2)(0 + 4) = 2

'y' of the midpoint is the average of 8 and 2 = (1/2)(8 + 2) = 5

The midpoint is (2, 5) .

That's choice-'c'.

There is midpoint formula for this problem:[ (x1+x2)/2, (y1+y2)/2 ], so all you need to do is plug in points given P(x1=0, y1=8) and Q(x2=4, y2=2), which is [ (0+4)/2, (8+2)/2 ]= [ 2, 5], so the answer is c)
