The number of large glasses that will be filled is 10 glasses.
What is a fraction?A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers.
Given that the large glass holds 5/6 cup of water and you have 8 cups of water. The number of glasses filled will be:
= 8 ÷ 5/6
= 8 × 6/5

two shirts cost 12:40$ how much will it cost to buy five of the shirts?
Answer:
12.50/26.256.25×5 31.25
Step-by-step explanation:
a farmer keeps cows,pigs and sheep on his farm. the ratio of cows to pigs to sheep on the farm is 2:7:16. work out the percentage of the animals that are sheep
Using percentages, we know that there are 64% of sheep in the total of all the animals, which is the ratio [Cows:pigs:sheep = 2:7:16].
What are percentages?A % is a quantity or ratio that, in mathematics, represents a portion of one hundred. It's frequently represented by the sign "%" or just "percent" or "pct." For instance, the decimal 0.35, or the fraction, represents 35%. By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.So, the percentage of sheep in the given ratio:
Cows:pigs:sheep = 2:7:16So, the total number of animals:
2+7+16 = 25Now, calculate 16 as what percentage of 25 as follows:
25/100 × x = 1625x = 1600x = 1600/25x = 64%
Therefore, using percentages, we know that there are 64% of sheep in the total of all the animals, which is the ratio [Cows:pigs:sheep = 2:7:16].

To determine the difference between two numbers, perform the subtraction process. When you remove a few items from a group of things, the group gets smaller.
Given, total count for both week is 41 larvae
Count for this week is 29 larvae.
Now, find the count for last week,
count = 41 - 29

(12-√-8)/2
solve as a complex number?
The solution to the expression (12-√-8)/2 as a complex number is 6 - i√2.
What is expression?
In mathematics, an expression is a combination of numbers, variables, and mathematical operations, such as addition, subtraction, multiplication, division, exponents, and roots.
The expression (12-√-8)/2 involves a square root of a negative number, which cannot be represented by a real number. Therefore, we need to extend the real numbers to the complex numbers to solve this expression.
To evaluate the square root of a negative number, we can use the imaginary unit, denoted by i, which is defined as the square root of -1. Then, we have:
√-8 = √(8) √(-1) = 2i√2
Substituting this value back into the original expression, we get:
(12-√-8)/2 = (12 - 2i√2)/2
Simplifying the expression by dividing both the numerator and denominator by 2, we get:
(12 - 2i√2)/2 = 6 - i√2
Therefore, the solution to the expression (12-√-8)/2 as a complex number is 6 - i√2.

Answer: 2.44736
Step-by-step explanation:
Assume the base unit of water is 555 gallons and the cost per unit is $1.74. How much money will be saved in a month by a family who conserves 8000 gallons of water per month?
1) Gathering the data
555 gallons ----- $ 1.74
2) If 8000 gallons could be spent
If a Family conserves 8000 gallons this family would not have an expense of?
Let's set a proportion for that:
555 g-----$1.74
8000g ---x
555x =13920 Dividing both sides by 555
x=25.08
If a family conserves 8000 gallons of water. They save $25.08 per month assuming that $1.74 is equal to 555 gallons of water.

Dave is trying on pants. Each pair is too small, fits well, or is too big. Dave estimates that 10%, percent of the pants he tries on will be too small and that 20% of the pants will be too big. If he were to try on 20 pairs of pants, which is the best prediction for the number of pairs of pants that would fit well?
The best prediction for the number of pair of pants that would fit well is 14.
What is the best prediction?Percentage is when value is converted to a number out of 100. Percentage is a measure of frequency. The sign that is used to represent percentages is %.
The first step is to determine the percentage of pair of pants that would fit well.
Percentage of the pair of pants that would fit well = 100% - percentage that are too big - percentage that are too small
Percentage of the pair of pants that would fit well = 100% - 10% - 20% = 70%
Number of pair of pants that would fit well = total pants that Dave tried x percentage that fits well
Number of pair of pants that would fit well = 20 x 70%
Number of pair of pants that would fit well = 20 x 0.7 = 14

What are the expressions in the blank space?
This is a problem involving algebraic expressions
Since the total for each row and column is the same
First, start from the second because it is complete. Add up all the expressions to get the total:
2x-3 + 3 + 2-x + x = 2x-2
Check the attached image. I labeled the boxes with alphabets for convenience.
A = 2x-2 -(1-2x) - (4x-1)-(3x-2) (Remember: 2x-2 is the total)
A = 2x-2 -1 +2x - 4x+1-3x+2 = -3x
B = 2x-2 -(8-3x) - (2x-3) -(1-2x)
B = 2x-2 -8+3x - 2x+3 -1+2x = 5x-8
C = 2x-2 -B -(6-5x) -(6x-7) where B = 5x-8
C = 2x-2 -5x+8 -6+5x -6x+7 = -4x+7
D = 2x-2 -3 -(4x-1) -(6-5x)
D = 2x-2 -3 -4x+1 -6+5x = 3x-10
E = 2x-2 -C -(2-x) -(3x-2)
E = 2x-2 +4x-7 -2+x-3x+2 = 4x-9
F = 2x-2 -A -x -(6x-7)
F = 2x-2 +3x -x -6x +7 = -2x+5
Therefore, the blank spaces should be filled with the expressions -3x, 5x-8, -4x+7, 3x-10, 4x-9 and -2x+5 represented with A, B, C, D, E and F respectively

In the question ,
it is given that
the total amount paid by the customer at the print shop = $6.00
total number of copies that the customer made = 68
the cost for printing 1 black and white copy = $0.08
the cost of printing 1 color copy = $0.15
let the number of black and white copies be "b"
let the number of color copies be "c" .
So ,
b + c = 68
and
the cost of b black and white copies is = 0.08b
the cost of c color copies is = 0.15c
the total cost = cost of b black and white copies + cost of c color copies
6.00 = 0.08b + 0.15c
0.08b + 0.15c = 6.00
