Set A Is Integers And B Is Whole Numbers Which One Is Correct...please Help

Answers

Answer 1
Answer: Choice J (lower right corner)

-20 and -7 are in circle A, but outside circle B

0, 9, 81 are in circle B

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

Explanation:

The set of whole numbers is

{0, 1, 2, 3, 4, ...}

While the set of integers is

{ ..., -3, -2, -1, 0, 1, 2, 3, ... }

The difference is that integers involves negative numbers.

-----------------

The upper left corner is incorrect because the "0" should be in set B since 0 is also a whole number. The lower left corner is also ruled out because of this reason.

The upper right corner (choice H) is incorrect as well because 10 and 46 are whole numbers also, so they belong in set B which is a better description/place for them.

So basically the numbers 0,1,2,3,... go in circle B. The negatives of those values will go in circle A, but outside circle B. Only choice J describes this kind of situation.

9. Is also wrong because both angles do not make a 90 degree angle.

10. Is wrong because both angles make a 90 degree angle when it should make a be 180 degrees.

Container R holds a solution that is 20% alcohol and Container S holds a solution that is 60% alcohol. How many liters of solution from each container should be used to create 2 liters of solution that is 50% alcohol?
*make two equations*

Answers

Answer:

The number of liters for container R = x = 0.5 liters

The number of liters for container S = y = 1.5 liters.

Step-by-step explanation:

Let the number of liters of container R = x

Let the number of liters of container S = y

We are told in the question : that

Container R holds a solution that is 20% alcohol

= 20% × x = 0.20x

Container S holds a solution that is 60% alcohol.

= 60% × y = 0.60y

How many liters of solution from each container should be used to create 2 liters of solution that is 50% alcohol?

Hence;

x + y = 2 ....... Equation 1

x = 2 - y

0.20x + 0.60y = 2 × 50%

0.20x + 0.60y = 1........ Equation 2

Substitute

2-y for x in Equation 3

0.20(2 - y) + 0.60y = 1

0.40 - 0.20y + 0.60y = 1

Collect like terms

0.40y = 1 - 0.40

0.40y = 0.60

y = 0.60/0.40

y = 1.5 liters

Note that :

x = 2 - y

x = 2 - 1.5

x = 0.5 liters

Therefore,

the number of liters for container R = x = 0.5 liters

the number of liters for container S = y = 1.5 liters.

Round 733,712 to the nearest thousand
733,712 ~

Answers

Answer:

734,000

Step-by-step explanation:

The thousands digit is the fourth digit from the right (1000) so we start by underlining that digit.

733,712

Look at the digit to the right of the underlined digit. If the number is 5 or more, add one to the underlined digit. Since 7 is 5 or more, we add one to the underlined digit.

All of the digits behind the underlined digits turn to zeros to hold the place values.

find the value of x. The answer is 53, but I need to show my work.

THANK YOU!!!

Answers

Answer:

53

Step-by-step explanation:

so first sutract the large angle from 360:

360 - 213 = 147

then subtract the other large known angle:

147 - 107 = 40

now we know the x - 13 = 40 so to find x we just have to add 13:

40 + 13 = 53

The answer to the question is 53.

cara is making a beaded necklace for a gift. she wants to spend more than $25 because she doesn´t want to seem like a cheap friend but no more than $60 because she isn´t that good of a friend either.the bead store charges $3 for large beads and $2 for small beads.if she buys 5 large beads, how many small beads can she buy to stay within her budget.

Answers

Answer:

5 small beads!

Step-by-step explanation:

Hey there!

If large beads are $3 each, and she buys 5 of them, our equation is $3 x 5 which equals $15. So Cara will spend $15 buying large beads.

Cara has $10 left now, because $25 - $15 = $10. Since each small bead is $2, we divide $10 (the total amount of money she has) by $2 (the cost of each bead). This will tell us how many she can buy! So $10 ÷ $2 is 5. Cara can buy 5 small beads!

I hope this helped you! Rating my answer and giving it a Thanks would sure help me out!
