Answer:
C)All integers are whole numbers.Step-by-step explanation:
A)whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)
integers are the numbers -∞ to +∞ (not including fraction, decimal numbers i.e -5.57, 7.74 etc)
since integers are the numbers including whole numbers thus the statement is true
B)Natural numbers are the numbers 1 to +∞ (not including fraction, decimal numbers i.e 6.89 etc)whereas whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)
hence, the statement is true
C)All Whole numbers are integers but not all integers are whole numbers
therefore, the statement is not true
D)the given definition is the perfect definition of rational numbers
hence, the statement is true

A. All whole numbers are integers.
[tex]\boxed{True}[/tex]
➺ Whole numbers include numbers from 0 to above. Integers include all numbers (negative & positive ones). Hence, all whole numbers are integers.
____________________
B. All natural numbers are whole numbers.
[tex]\boxed{True}[/tex]
➺ As said above, whole numbers include numbers from 0 to above. Natural numbers on the other hand include numbers from +1 to above (right side of the number line). So, all natural numbers come under whole numbers.
____________________
C. All integers are whole numbers.
[tex]\boxed{False}[/tex]
➺ Integers include both negative & positive numbers while whole numbers only include numbers from 0 to above (right side of the number line). Since, negative numbers don't come under whole numbers, integers can't be categorised as whole numbers. •°• All integers are not whole numbers.....but all whole numbers are integers.
____________________
D. All fractions of form [tex]\frac{p}{q}[/tex], where p and q are integers and q [tex]\neq[/tex] 0, are rational numbers.
[tex]\boxed{True}[/tex]
➺ This is the definition of rational numbers. All fractions are under rational numbers, so this definition stands true for fractions as well.

[tex]\large\underbrace{ \overbrace{ \mathfrak{Answer}}}[/tex]
⟹ So, the statement which doesn't match or is NOT true will be ➳ C. All integers are whole numbers.

Answer:
19.5°
Step-by-step explanation:
The sum of any 3 angles of a triangle is 180.
That being so 33.5 + 127 + F = 180.
33.5 +127 + F - 33.5 = 180 - 33.5
127 + F = 146.5
127 + F - 127 = 146.5 - 127
F = 19.5

What is the mean of the data? Hours of TV Watched on Saturdays X Х XX 4 5 6 7 Hours 5.5 7 4 9
Answer: 5.9375
Step-by-step explanation:
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set.
Average = Sum / Count
= 47.5 / 8
= 5.9375
Select all ratios equivalent to 20:4 A. 8:1 B. 10:2 C. 15:3
Answer:
b 10:2 ,, c 15:3
Step-by-step explanation:
20:4 by dividing 4 from both sides you get the ratio
5 :1
so simplify the other ratios and find one that equals this one
A is already in simplest form 8:1
so it's refused
B 10:2 by dividing 2 from both sides you get the ratio 5 :1
C 15:3 by dividing 3 from both sides you get the ratio 5 :1
so both B and C are correct answers
Hope this helped! :)
Only answer if you know the correct answer! Thanks! :)

A cylinder with volume of 143^3 cm has 3 spheres inside. Each sphere has a radius of 2cm. What is the volume in the cylinder not taken up with spheres (blank space)?
Please provide the equation and steps you used!
Answer:Equation: V = πr^2h
Steps:
1. Calculate the volume of each sphere: V = 4/3πr^3 = 4/3π(2cm)^3 = 33.51 cm^3
2. Calculate the total volume of the 3 spheres: 3 x 33.51 cm^3 = 100.53 cm^3
3. Calculate the volume of the cylinder not taken up with spheres: 143^3 cm^3 - 100.53 cm^3 = 42.47 cm^3

how can you find the vertex of a parabola if you know it's focus and directrix? in my equation, the focus is (6,4) and the directrix is y=-2
Answer:
The vertex would be (6,1)
Step-by-step explanation:
The vertex is the midway between the focus and the directrix. The X of the vertex would be the same but to get the Y of the vertex you would need to take the average of the Y values. (6, 4 + (-2)/2) (6,1)

A store pays $275 for a table and marks the price up by 50%. What is the amount of the mark-up ?
Answer:
$387.50
Step-by-step explanation:
You can get the answer 2 different ways. First you could take $275/2 = $137.50
Or
$275*0.50 = 137.50
add $275+137.50 =$387.50

Step-by-step explanation:
How do I add a percentage (%) tip to a total of a bill? (Ex - Total : 3.00 with a %18 tip)
To calculate a gratuity or tip on any calculator it is a simple multiplication. In general, the tip amount is the cost times 0.xx and your total including tip, is the cost times 1.xx where xx = the percent you want to leave. If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.
Let's say you and a friend had dinner that cost $26.50. You had good service and want to leave an 18% gratuity. Put the percentage in decimal form (0.18) then multiply the cost by this number.
26.50 * 0.18 = 4.77. So your tip is $4.77.
An easy way to get the total amount, dinner plus tip, is to multiply the total by 1.18. 26.50 * 1.18 = 31.27. This works mathematically because you want to know your original cost plus the tip which is written as 26.50 + (26.50 * 0.18) = ? Factoring out the 26.50 from this equation you get 26.50 * (1 + 0.18) = 26.50 * 1.18.
How to calculate a tip in your head
You can get a good approximation of a tip by doing it in your head this way.
You can find 10% of your bill by moving the decimal one place to the left. If 26.50 is 100% then 10% is 2.65. Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30. Now you know the tip you could leave ranging from poor to good, $2.65 to $5.30. To find 15%, halfway in between, we know 15% is 10% plus 1/2 of 10% (5%). 2.65 plus about 1.30 is 3.95.
Now you have
10% is 2.65 - by moving decimal 1 place left
15% is 3.95 - 10% + 1/2 of 10%
20% is 5.30 - 10% * 2
This is plenty of information to make a good guess at the tip amount you should leave. If you decide on about 18%, 4.50 to 5.00 would be a safe guess.

Answer:
put to percentage as a decimal (ex. 0.18) then you add that to the total amount

Nabhitha buys cookies and onions at the store.
She pays a total of $60.39.
She pays a total of $4.79 for the cookies.
She buys 8 bags of onions that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of onions costs.
Answer:
8x+4.79=60.39
Step-by-step explanation:
If you want this solved,
60.39-4.79 = 55.6
55.6/8 =6.95
One bag of onions = $6.95

Answer:
D. 33
Step-by-step explanation:
The two lines closing -33 in are the absolute value lines. Absolute value means how far is that number from 0. Since distance HAS to be positive, the answer is always the number inside the two lines, but positive. No matter if it starts off as negative or positive.
