Answer:

he has 8 classes 3 hours long, so 8×3 is how long he IS is class. subtract 24 from 63 and you get how long he is NOT in class. he is NOT in class for 39 hours.

Answer:

4

Step-by-step explanation:

4d + 1 = 17

1 + 4d = 17

Move all terms containing d to the left, all other terms to the right.

1 + -1 + 4d = 17 + -1

0 + 4d = 17 + -1

4d = 17 + -1

4d = 16

d = 4

Answer: The least common multiple is 65700

Step-by-step explanation:

To begin, find the prime factors of the given numbers, (and you find they have very little in common.)

9=3×3   25=5×5   36=2×2×3×3  73= 73×1  (73 is a prime number)

Only the 3's of 36 overlap with the 3's of 9

To find the LCM you must multiply all the prime factors that don't overlap:

3×3×5×5×2×2×73

If the 73 is changed to 72, the LCM is a somewhat lower number: 1800.

To test these LCM's try dividing by any of the factors or numbers given.

If the quotient is not a whole number, the LCM doesn't include that factor.

Answer:

x^2 + y^2 - 8x + 18y + 48 = 0

Step-by-step explanation:

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the centre of circle and r is the radius of circle. hence the standard form of equation can be obtained by expanding

(x-4)^2 + {y-(-9)}^2 = 7^2

Answer:

Infinitely many solutions

Step-by-step explanation: You have to distribute 3(2x+5) which equals 6x+15 which is equal to the other equation. Same slope same y-intercept means (infinitely many solutions).

Answer:

Step-by-step explanation:

opposite angles are equal

12x - 18 = 8x + 10

combine similar terms:

12x - 8x = 10 + 18

4x = 28

x = 28/4

x = 7

plugin the value of x=7 back into the equation to solve the angle

= 12x - 18

= 12(7) - 18

= 66

= 8x + 10

= 8(7) + 10

= 66

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

Explanation:

Utility is another way of saying happiness more or less. Marginal utility is getting that extra bit of satisfaction from buying/consuming one additional item. Saying the marginal utility is diminishing but not negative, means we have an increasing utility curve that has its rate of increase slow down. An example would be a log curve.

Inflation can be thought of as an expense. For example, if it costs $1 to get a loaf of bread one year, and then next year that cost jumps to $1.50 for that same loaf of bread, then the worker has effectively lost 50 cents on their paycheck. Zero inflation means there isn't any such expense. So in a way, this is like getting a raise.

Being paid more due to higher labor costs means that the worker gets even more money on top of the bonus money saved from zero inflation. These two aspects would provide a lot of incentive for the person to work more hours. Of course, there would be a point in which the marginal utility is far too small. In other words, the amount of additional money earned isn't worth the additional time spent working. This is likely when the worker would take time off, seek out a raise, or find some other job.

Answer:

What are the options?

Step-by-step explanation:

Because we need it.

Answer:

Diverges

Step-by-step explanation:

The order of the numerator (2) is greater than the order of the denominator (1).  So the sequence will diverge as n approaches infinity.

I think that it is a strong, almost unpleasant flavor because  it cannot be a verb because nip in this context is what the cheese has and that cannot be a verb.

I don't think that it is a cold, unpleasant feeling because it's cheese, and the feeling is usually used to describe things you touch with your hands.

Answer:

It is a string, almost unpleasant, flavor

Step-by-step explanation:

Answer:

a) 68 % will lie between 30 and 44 ounces

b) between 23 and 44 ounces will lie 81,5 %

Step-by-step explanation: See Annex

a) Normal Distribution  N ( 37, 7)

The Empirical Rule establishes that 68 % of values will be at

μ  ±  1 σ      where μ is the mean and σ the standard deviation

Then:   37 - 7  = 30    and 37 + 7 = 44

68 % of the values will lie between  30 and 44 ounces

b) And between  23 and 44 we should find:

We have 95 %  of values between

μ  ± 2*σ  

In our case to the left of the value (mean 0 ) and up to the value 23 we get 95/2 = 47,5 % and to the right of the value (mean 0 ) and up to 44 we half 68/2 = 34 %

Then between 23 and 44, we have 47,5 + 34 = 81,5 %

Answer:

  40°

Step-by-step explanation:

Since DP is an angle bisector, the angles it creates are congruent:

  ∠1 = ∠2 = 20°

The requested angle is the sum of the measures of angles 1 and 2:

  ∠FDE = ∠1 + ∠2 = 20° +20°

  ∠FDE = 40°
