Which of the following situations combine to make zero?
A- A friend opens a checking account with $30. His first purchase made with his debit card totals $28
B- The temperature falls 10 degrees below zero and then rises 20 degrees to be 10º F
C- A friend borrows $20 and promises to return double the amount.
D- A start up business has income equal to its expenses.
Answers
Answer:
D
Step-by-step explanation:
Why A is wrong:
If a friend has $30 in his checking account and he made a purchase of $28, the equation would be:
30-28 = $2, which does not equal zero.
Why B is wrong:
The temperature was zero and went down to negative ten. It went up to 10, not zero. So this is also wrong.
Why C is wrong:
A friend borrowed $20 dollars and promised to return double the amount, $40. The equation for this is:
20 - 40 = -20, which also does not equal zero
Why D is correct:
Income is how much you earn
Expenses is how much you pay.
If both of them are equal, then your income is zero, which is the correct answer.
Hope this helps :)

Answer:
4.5 cm
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
121.5 pi = 4/3 pi r^3
Divide each side by pi
121.5 = 4/3 r^3
Multiply each side by 3/4
3/4 *121.5 = 3/4 * 4/3 r^3
91.125 = r^3
Take the cube root of each side
(91.125)^ (1/3) = r^3 ^(1/3)
4.5 = r

Answers
Answer:
0.8%
Step-by-step explanation:
There is a decrease in percentage by 0.8%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
The given decimal numbers are $18.75 and $18.60.
We know that, percentage change = (Original price-New price)/Original price ×100
= (18.75-18.60)/18.75 ×100
= 0.15/18.75 ×100
= 0.008×100
= 0.8%
Therefore, there is a decrease in percentage by 0.8%.

The numbers are 8 and 6
Step-by-step explanation:
Let x and y be the two numbers
x+y = 14
x-y = 2
Add the two equations together
x+y = 14
x-y = 2
--------------
2x +0y = 16
Divide by 2
2x/2 = 16/2
x = 8
Now find y
x+y = 14
8+y =14
Subtract 8 from each side

2. At a fair, each person can spin two wheels of chance. The first wheel has the numbers 1, 2, and 3. The second wheel has the letters A and B. (d) List all the possible outcomes of the compound event. (e) If you spin both wheels, what is the probability that you get either a 1 or an A? Explain.
And pls don’t answer if you don’t know it.
Answers
Answer:
Possible outcomes: 1a 1b 2a 2b 3a 3b
Outcomes for spinning a one = 2
1a, and 1b 2/6
Outcomes for spinning an "a" = 3
1a, 2a, and 3a.
1a is already in the first set so we can exclude it. 2/6
2/6+2/6=4/6
There is a 4/6 or 2/3 chance of getting either an a or an 1
Answer:
(d) 1A, 1B, 2A, 2B, 3A, 3B
(e) 2/3 or 66.66% chance
Explanation is below
Step-by-step explanation:
(d) The Total outcomes are 3*2 = 6, because there are 3 numbers and 2 letters.
The outcomes are:
1A
1B
2A
2B
3A
3B
(e) Of the 6 outcomes, 3 of them have A and 2 of them have 1. But one of them has an A and 1, so it is 4 outcomes: 1A, 1B, 2A, and 3A.
So it is 4/6 = 2/3, or 66.66...% chance

Four playful mathematicians were eating lunch together at an outdoor cafe. They noticed a diamond-encrusted Rolex had been left behind at the table next to them, so they quickly looked around for the person who had vacated the table. They saw the owner of the watch driving away. "Quick, get the license plate!" urged one of the mathematicians, seeing that it was only a four-digit number.
When the car had disappeared around the corner, they put together these characteristics they'd noticed about the number:
The first said, "One of the digits is neither prime nor composite."
The second contributed, "The digit in the hundreds place is three times the digit in the thousands place."
The third added, "The digit in the ones place is four times greater than the digit in the tens place."
The fourth piped up with the last bit of information. "The smallest prime number is in the thousands place. We have enough information to help us locate the owner of the watch."
What number did the four playful mathematicians see on the license plate?
Answers
Answer: The licence plate number would be 2614
Step-by-step explanation:
The number 2614 four playful mathematicians see on the licence plate.
What is number?A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56 etc. are the numbers.
We have some information about the four-digit number:
One of the digits is neither prime nor composite.The digit in the hundreds place is three times the digit in the thousands place.The digit in the ones place is four times greater than the digit in the tens place.The smallest prime number is in the thousands place.Based on the information given, the number would be 2614 which follows the above conditions.
Thus, the number 2614 four playful mathematicians see on the licence plate.
