Answer:

a. 28

b. 6.5

c. 30

Step-by-step explanation:

1% = 80÷100

35% = 0.8×35

1% = 0.65

0.65 × 10 = 6.5

1% = 0.5

60% = 0.5×60

Answer:

28

6.5

30

another way you can get these answers is by cross multiplying. In order to do that you need to identify the percent, the whole (of), and the part (is). In identifying the whole and the part, look for the word is, and the word of. The number that is associated with is either the part or the whole. (There is <u>6</u> out of <u>80</u>, what is the percentage?) always set the percentage out of a hundred.

So from there we set up the proportion:

ONE

(we don't know the part in any of them)

X/80=35/100 (cross multiply by putting the numbers on top of each other for the fractions)

TWO

X/65=10/100

THREE

X/50=60/100

Hope this helps, have a good day and remember to be tiger fierce!! :) (also, sorry that it is late.)

Which of the following changes will always be true for an exothermic process?
Ivenika [448]
Given that I no not see any explanation in the previos answer, I think you can benefit of this.

Exothermic refers only to the fact that the reaction releases energy in the form of heat when occurs. So, the enthalpy is higher at start and lower and the end.

Seen in this way, you can deduct that the change in enthalpy is negative, which is what the third option says.

The weight of Lyle’s dog increased from 29.7 pounds to 48.9 pounds in an 8-month period. What was the dog’s average weight incre
krok68 [10]
First subtract the weight the dog weighs now to the weight he was:

48.9
- 29.7
------------
19.2

Then take the number you got which is the weight the dog gain in total, and divide it by the months the dog gained weight to get the average weight gained each month:


19.2/8 = 2.4

The average weight gain each month was 2.4 pounds.

Hope this helped you!
