Can someone please illustrate the sets using a venn diagram and answer the following: A = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30} B = {4, 8, 12, 16, 20, 24, 28, 32, 36, 40} C = {6, 12, 18, 24, 30, 36, 42, 48, 54, 60} 1. Cardinality of Set B 6. ( A U B ) intesection C 2. Write Set C in set- builder form 7. A U B U C 3. Write Set A in set- builder form 8. A´ 4. A U B 9. B - c 5. " B intersection C" 10. ( A U B ) - C

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
