Answer:
25/84
Step-by-step explanation:
1. 2 1/10 is mixed number fraction so convert it into an improper fraction.
~ Multiply whole number and denominator and add the numerator of 1
~ Improper fraction: 21/10
2. So, new equation is (5/8) / (21/10)
3. Use the Keep, Change, Flip method:
~ Keep the 5/8
~ Change division to multiplication
~ Flip the improper fraction to 10/21
4. Solve the equation:
~ (5/8) x (10/21) = 50/ 168
5. Reduce fraction:
~ By 2
~ 25/84

Give breif detail and description this question contains 15 points (will also mark as brainliest)
The 8 consecutive numbers are 12, 13, 14, 15, 16, 17, 18, 19 respectively.
What are algebraic expressions?Algebraic expressions are simply described as arithmetic expressions that are made up of arithmetic terms, constants, variables, factors and coefficients.
These expressions are also made up of arithmetic operations which includes;
ParenthesesBracketDivisionMultiplicationAdditionSubtraction, etcBased on the information given, we have;
x + x + 1 + x + 2 + x + 3 + x + 4 + x + 5 + x + 6 + x + 7 = 124
Now, collect like terms, we get;
8x + 28 = 124
8x = 124 - 28
Subtract like terms
8x = 96
To determine the value of x, make it the subject by dividing both sides by 8, we have;
8x/8 = 96/8
x = 12
Then,
x = 12
x + 1 = 13
x + 2 = 14
x + 3 = 15
x + 4 = 16
x + 5 = 17
x + 6 = 18
x + 7 = 19
Hence, the values are 12, 13, 14, 15, 16, 17, 18 and 19 respectively.

ignoring all other issues, how many pounds of grain supplement should farmer ben feed his cows if the price of milk is $0.20 per pound and the price of grain supplement is $0.70 per pound?
The most appropriate choice for profit and loss will be given by
Uncle Ben will feed his cows 2 pounds of grain supplement.
What is profit and loss?
If the selling price is more than the cost price, then the difference between the selling price and the cost price will give the profit.
If the selling price is less than the cost price, then the difference between the selling price and the cost price will give the loss.
Here,
For 1 pound
Cost price of grain supplement = [tex]0.70 \times 1[/tex]
= $[tex]$0.70[/tex]
Selling price of milk = [tex]0.20 \times 5[/tex]
= $[tex]1[/tex]
Profit = $([tex]1 - 0.70[/tex])
= $0.30
For 2 pounds
Cost price of grain supplement = [tex]0.70 \times 2[/tex]
= $[tex]$1.40[/tex]
Selling price of milk = [tex]0.20 \times 9[/tex]
= $[tex]1.80[/tex]
Profit = $([tex]1.80 - 1.40[/tex])
= $0.40
For 3 pounds
Cost price of grain supplement = [tex]0.70 \times 3[/tex]
= $[tex]$2.10[/tex]
Selling price of milk = [tex]0.20 \times 12.3[/tex]
= $2.46
Profit = $([tex]2.46 - 2.10[/tex])
= $0.36
For 4 pounds
Cost price of grain supplement = [tex]0.70 \times 4[/tex]
= $[tex]$2.80[/tex]
Selling price of milk = [tex]0.20 \times 15.5[/tex]
= $3.1
Profit = $([tex]3.1 - 2.80[/tex])
= $0.30
For 5 pounds
Cost price of grain supplement = [tex]0.70 \times 5[/tex]
= $[tex]$3.50[/tex]
Selling price of milk = [tex]0.20 \times 18[/tex]
= $3.60
Profit = $([tex]3.60 - 3.50[/tex])
= $0.10
For 6 pounds
Cost price of grain supplement = [tex]0.70 \times 6[/tex]
= $[tex]$4.20[/tex]
Selling price of milk = [tex]0.20 \times 20[/tex]
= $4
Loss = $([tex]4.20 - 4[/tex])
= $0.20
For 7 pounds
Cost price of grain supplement = [tex]0.70 \times 7[/tex]
= $[tex]4.90[/tex]
Selling price of milk = [tex]0.20 \times 21.5[/tex]
= $[tex]4.30[/tex]
Loss = $([tex]4.90 - 4.30[/tex])
= $0.60
For 8 pound
Cost price of grain supplement = [tex]0.70 \times 8[/tex]
= $[tex]$5.60[/tex]
Selling price of milk = [tex]0.20 \times 22.5[/tex]
= $[tex]4.50[/tex]
Loss = $([tex]5.60 - 4.50[/tex])
= $1.10
For 9 pounds
Cost price of grain supplement = [tex]0.70 * 9[/tex]
= $[tex]6.30[/tex]
Selling price of milk = [tex]0.20 * 23[/tex]
= $[tex]4.60[/tex]
Loss = $([tex]6.30 - 4.60[/tex])
= $1.70

Based on the mass of the molecules of oxygen that the scientist determined, the number of significant digits in the solution is 2.
How to count significant digits?When counting the significant figures in a number, the first rule is that any digit that isn't a zero would be considered a significant digit.
Zeros that are trailing in a number however, and are not considered decimals, are not counted as significant digits. This means that both the 2 number 2s in the figure will be significant figures.

$48.27
The new balance = $320.39 + $100 - $97.54 - $48.27

A withdrawal can be made for many different purposes, such as paying an employee back for a company expense or covering a cash-intensive business expense like entertaining a significant client at a sporting event. A withdrawal can also refer to the departure of money from an employer-sponsored retirement plan, like a 401k. Additionally, some businesses have a petty cash fund set up for various modest charges; certain incidental expenses may also be paid out of this account. An owner's draw or accounting drawing is not taxed in the traditional sense.To learn more about Withdrawal, refer to:

In a large population, 56% of the people have been vaccinated. If 5 people are randomly selected, what is the probability that at least one of them has been vaccinated?
The likelihood that someone has received a vaccination equals one minus the likelihood that no one has. The likelihood that a randomly chosen individual in a large population IS NOT immunized = 1 - 0.54 = 0.46.
The likelihood that the three randomly chosen individuals are not all immunized is 0.463, hence the likelihood that at least one of them has been immunized is 1 - 0.463.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

The multiples of 4 between 100 and 150
Answer:
104 ;108;112;116;120;124;128;132;136 ;140;144;148
Answer:
104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148
Step-by-step explanation:
A multiple of 4 can generally be defined as divisible by 4.
We can define an equation for it: [tex]4n[/tex] where n is an integer.
From here we can see that if n=25, we have a number of 100 which indeed is a multiple of 4 since dividing it by 4 results in 25 which makes sense since 100 is the result of 4 * 25.
Now starting from 100 (excluding 100 since between 100 and 150), or n=25, we can increase the value of the number by 4, or n by 1 which is doing the same thing.
So start at 100, then 100+4 = 104, then 104+4=108 and so on... until you reach a number greater than or equal to 150, and if it is 150 make sure to exclude it since it says between 100 and 150 which implies it's excluding the end points.
This gives us a result of: 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

The sum of three mixed numbers is 24 4/5. Two of the number are 8 2/3 and 6 5/6. What is the third number?
The numerical value of the third number in an improper and mixed fraction form is 93/10 and 9 3/10 respectively.
What is the value of the third number?Given the data in the question;
Let 'x' represent the third number
Sum of the three numbers = 24 4/5First number = 8 2/3Second number = 6 5/6Third number = xFirst, convert the numbers form mixed fractions to improper fractions
Sum of the three numbers = 24 4/5 = ( 24×5 + 4 )/5 = 124/5
First number = 8 2/3 = ( 8×3 + 2 )/3 = 26/3
Second number = 6 5/6 = ( 6×6 + 5 )/2 = 41/6
Now, to determine the third value, equate the sum of the three numbers to the total and solve for x
26/3 + 41/6 + x = 124/5
( 156 + 123 )/18 + x = 124/5
( 279 )/18 + x = 124/5
31/2 + x = 124/5
x = 124/5 - 31/2
x = ( 248 - 155 )/10
x = ( 93 )/10
x = 93/10
x = 9 3/10
Therefore, the value of the third number is 93/10 or 9 3/10.
