Which number is rational?
Answer:
We need some numbers to work with to truly answer this. However here's a definition of a rational numbers
A rational number is any number that isn't infinite and non-repeating. So decimals, fractions, repeating numbers/decimals like 1.535353.... (53 is the "pattern") are all rational and fair game. Numbers like pi (π), "imperfect" square roots, etc. that don't repeat and are infinite or NOT RATIONAL.

Assume that you knew that the value of the coins totaled $62.00. What is one possible combination of pennies
and quarters that sum to $62.00.
Answer:
Step-by-step explanation:Imagine taking a handful of coins from your pocket or purse and placing them on your desk. How would you determine the value of that pile of coins?
If you can form a step-by-step plan for finding the total value of the coins, it will help you as you begin solving coin word problems.
One way to bring some order to the mess of coins would be to separate the coins into stacks according to their value. Quarters would go with quarters, dimes with dimes, nickels with nickels, and so on. To get the total value of all the coins, you would add the total value of each pile.

Gregory can buy 4 pounds of wheat flour for $8 and 5 pounds of rye flour for $20. He has $12 to spend on a flour mixture. What linear equation in standard form can Gregory use to model the situation?
Answer:
2x + 4y = 12Step-by-step explanation:
Wheat flour
4 pounds for $8 ⇒ 1 pound for $8/4 = $2Rye flour
5 pounds for $20 ⇒ 1 pound for $20/5 = $4Equation for total:

Ms. Bailey is taking her children and their friends to the movies. She will pay $10 for her adult ticket and $6 for each child ticket. Ms. Bailey spends $46.00 at the movies. Write and solve an equation to determine the number of child tickets Ms. Bailey purchases.
Equation
10+6x=46
subtract both sides by 10
10-10 46-10
to get 6x=36
divide both sides by six to isolate the variable
6x/6 36/6
which gives you
x=6
6x + 10 = 46 is the equation to determine the number of child tickets Ms. Bailey purchases and Ms. Bailey purchases 6 child tickets.
Let's assume that Ms. Bailey purchases "x" child tickets.
The cost of each child ticket is $6, so the total cost of child tickets would be 6x dollars.
Ms. Bailey also purchases one adult ticket for $10.
The total cost spent by Ms. Bailey at the movies is $46. Therefore, we can write the equation:
6x + 10 = 46
To solve for "x," we can start by subtracting 10 from both sides of the equation:
6x = 46 - 10
6x = 36
Divide both sides of the equation by 6 to isolate "x":
x = 36/6
x = 6
Therefore, Ms. Bailey purchases 6 child tickets.

A marathon is 26.2 miles long. There is a water station every 114 miles along the race route and at the finish line. How many water stations are needed for this marathon?
Answer: 21 water stations
Step-by-step explanation:
From the question, we are informed that a marathon is 26.2 miles long and that there is a water station every 1 1/4miles along the race route and at the finish line.
To get the number of water stations that are needed for this marathon, we divide 26.2 miles by 1 1/4miles. This will be:
= 26.2miles/1 1/4 miles
= 26.2 miles/1.25 miles
= 20.96
= 21 water stations

how many litres of milk can be put in six hemispherical bowl each of diameter 35cm
Answer:
Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
Step-by-step explanation:
The volume of a hemisphere ([tex]V[/tex]), measured in cubic centimetres, is obtained from this formula:
[tex]V = \frac{2\pi}{3}\cdot R^{3}[/tex]
Where [tex]R[/tex] is the radius of the hemisphere, measured in centimetres.
We know that radius is the half of the diameter ([tex]D[/tex]), measured in centimetres, then:
[tex]R = 0.5\cdot D[/tex]
([tex]D = 35\,cm[/tex])
[tex]R = 0.5\cdot (35\,cm)[/tex]
[tex]R = 17.5\,cm[/tex]
Now, we get the volume of each hemispherical bowl:
[tex]V = \frac{2\pi}{3} \cdot (17.5\,cm)^{3}[/tex]
[tex]V \approx 11224.649\,cm^{3}[/tex]
The total volume of six hemispherical bowl is:
[tex]V_{T} = 6\cdot V[/tex]
[tex]V_{T}= 6\cdot (11224.649\,cm^{3})[/tex]
[tex]V_{T} = 67347.894\,cm^{3}[/tex]
From Physics we know that 1 litre equals 1000 cubic centimetres. Then:
[tex]V_{T} = 67.348\,L[/tex]
Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.

Answer: -3 13/40
Steps: (-⅛ + ⅖) - 3 ⅗
Convert mixed numbers to improper fractions: 3⅗ = 18/5
(-⅛ + ⅖) - 18/5
Remove the parentheses: -⅛ + ⅖ - 18/5
Find the common denominator which is 40.
So: -5/40 + 16/40 - 144/40
Since the denominators are equal, combine the fractions: -5 + 16 -144 divided by 40.
Add/ subtract the numbers: -5 + 16 - 144 = -133
= -133/40
Convert improper fractions to mixed numbers: 133/40 = 3 13/40
The answer is -3 13/40

(x+8)(x+11)=0 solve the following equation using the zero product property
Answer:
x = -8 x = -11
Step-by-step explanation:
(x+8)(x+11)=0
Using the zero product property
x+8 =0 x+11 =0
X+8-8 =0-8 x+11-1 = 0-11
x = -8 x = -11
-3(2x - 1) + 8x = 15
Answer:
x = 6
Step-by-step explanation:
use distributive property to multiply the -3 with the numbers inside the parentheses
-6x + 3 + 8x = 15
combine like terms
2x + 3 = 15
subtract 3 from both sides
2x = 12
x = 6
Answer:
x=6
Step-by-step explanation:
Distribute -3 through the parentheses
Collect like terms
Move constant to the right hand side and change it sign
Subtract the numbers
Divide both sides by 2
