Glen is looking into buying a piece of land. He estimates that the land measures 100 yd by 850 yd. The land is actually 140 yd by 940 yd. What is the percent error in the estimated area of the land? A. 35.4%
B. 17.7%
C. 64.6%
D. 32.3%

Answers

Answer 1

Answer: 1) First find the areas:
100 * 850 = 85000
140 * 940 = 131600
2) Find the percent error in the area
percent error = (experimental value - accepted value)/(accepted value) *100
% error = (85000 - 131600)/(131600) * 100 = 35.4%

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
of the many aces, experts, and geniuses that prowl this site constantly,
can weigh in and show me my blunder on the first attempt.

How much is 96.25 in a fraction

Answers

77/80 is the fraction in its simplest form

the answer is 96 1/4. 25 is one fourth of 100 and 96 is a whole number so the answer is 96 1/4 or it can also be 385/4 but 96 1/4 is in simplest form

Jose asks his friends to guess the higher of two grades he received on his math tests. He gives them two hints. The difference of the two grades is 16. The sum of one-eighth of the higher grade and one-half of the lower grade is 52. The system that represents his scores is below.. . x – y = 16. . x + y = 52. . What is the higher grade of Jose’s two tests?. . 48.
52.
80.
96

Answers

x - y = 16
1/8 x + 1/2 y = 52 / * 2 ( multiply both sides by 2 )
-------------------------
x - y = 16
+
1/4 x + y = 104
----------------------
1.25 x = 120
x = 120 : 1.25
x = 96
