If the original quantity is 10 and the new quantity is 13 what is the percent increase

Harman [31]

Answer:

As per the given statement:

Original quantity = 10

New quantity = 13

Change in quantity = New quantity - original quantity = 13-10 = 3

We have to find the percent increase.

$\text{Percent increase} = \frac{\text{Change in quantity}}{\text{Original quanity}} \times 100$

Substitute the given values we have;

$\text{Percent increase} = \frac{3}{10} \times 100 = 30\%$

Therefore, the percent increase is, 30%.

23. Find the value of x.<br> (5x + 4)' X (8x - 71)

r-ruslan [8.4K]

Answer:

x = 71/8

Step-by-step explanation:

Solve for x:

5 X (8 x - 71) = 0

Divide both sides by 5 X:

8 x - 71 = 0

Add 71 to both sides:

8 x = 71

Divide both sides by 8:

For each of these relations on the set {21, 22, 23, 24}, decide whether it is reflexive, whether it is symmetric, whether it is

bonufazy [111]

Answer:

Step-by-step explanation:

I. { (22,22) , (22,23) , (22,24) , (23,22) , (23,23) , (23,24) }

Reflexive : True because we see the pairs (22,22) , (23,23)..

Symmetrix : NO, as we see the pairs (22,24) BUT NOT (24,22)

Transitive : YES, As we see (22,22 ) and (22, 24) , we see the pairs (22,24)

Antisymmetric : NO

II){ (21,21) , (21,22) , (22,21) , (22,22) , (23,23) , (24,24) }

Reflexive : True because we see the pairs (22,22) , (23,23) (21,21)

Symmetrix : Yes, as we see the pairs (21,22) AND (22,21)

Transitive : YES,

Antisymmetric : NO
