report (3,000 words), and begs Monica to type it for her. If Monica agrees, how long will it
take her?
If Monica agrees to type the report for her manager, she will take 40 minutes, based on the unit rate.
What is the unit rate coefficient?The unit rate refers to the coefficient of proportionality between two proportional quantities.
The unit rate is computed as the quotient of the total number and the typing speed or rate per minute.
In this situation, we are given the total words of the report and Monica's typing speed. Based on this, we can compute the time for her to complete the typing by dividing the total words by the typing speed.
The total number of words in the report = 3,000 words
Monica's typing rate per minute = 75 words per minute
The time for Monica to complete typing the 3,000-word report = 40 minutes (3,000/75).

a bowl contains 675 sweets
ratio of red to blue sweets is 3:7
ratio of blue to green sweets is 4:5
calculate the number of blue sweets
Answer:
We know that the ratio of blue to green sweets is 4:5
We can let y be the number of green sweets
the total number of sweets is 675, and we know that the ratio of blue to green sweets is 4:5, so we can set up the equation:
x + y = 675
where x is the number of blue sweets and y is the number of green sweets.
Also we know that x:y = 4:5
by cross multiplying x * 5 = y * 4
x = (5/4) y
Now we can substitute x in the first equation:
(5/4) y + y = 675
by combining like terms we get:
9/4 y = 675
multiply both sides by 4/9 to get:
y = (675 * 4) / 9
y = 300
the number of blue sweets is:
x = (5/4) y = (5/4) * 300 = 375
so the number of blue sweets is 375.

Thus there can be no more than 8 total peeps when the number is less than 130.
what is proportionality ?Relationships that have the same ratio over time are said to be proportional. For instance, how many trees there are in an orchard and how many apples there are in a harvest of apples are determined by the average number of apples per tree. Proportional in mathematics refers to a linear relationship between two numbers or variables. When the first quantity doubles, so does the other. When one of the variables drops to 1/100th of its previous value, the other also decreases.
When two quantities are proportional, it means that when one rises, the other rises as well, and the ratio between the two quantities stays the same at all values. As an example, consider the diameter and circumference of a circle.

Using the Law of Sines to find a triangle with one obtuse angle if
After using law of sine the measure of triangle ∠B=50° , ∠C= 85° and
c= 36.4.
What is sine law?
According to the law of sine, or sine law, the ratio of a triangle's side length to the sine of the opposing angle remains constant for all three sides. The sine rule is another name for it.
Here the given triangle measures are , ∠A = 45° , a = 26 and b=28.
Now using sine law then
=> [tex]\frac{a}{sin A} = \frac{b}{sin B}[/tex]
=> [tex]\frac{26}{sin 45} = \frac{28}{sin B}[/tex]
=> sin B = [tex]\frac{28\times sin 45}{26}[/tex]
=> sin B =0.7615
=> ∠B= 49.60° ≅ 50°
Now we know that sum of all angles in triangle is add upto 180°.
=> ∠A+∠B+∠C = 180°
=> 45°+50°+∠C = 180°
=> ∠C = 180°-95° = 85°
Now again using sine law then
=> [tex]\frac{b}{sin B} = \frac{c}{sin C}[/tex]
=> [tex]\frac{28}{sin 50}=\frac{c}{ sin85}[/tex]
=> c = [tex]\frac{28\times sin 85}{sin 50}[/tex]
=> c = 36.4
Hence the answers are ∠B=50° , ∠C= 85° and c= 36.4

The individual' weight made up of fat is 26.27 pounds.
What portion of his weight—in pounds—is made up of fat?The individual's body fat percentage is 15.7%, which means that 15.7% of their total weight is fat.To calculate the amount of fat in pounds, we simply need to calculate 15.7% of 166 pounds.To do this, we can use the formula:Percentage X Total amount = AmountSo, in this case, we can plug in our values:15.7% X 166 = 25.922Therefore, the individual has 25.922 pounds of fat. To convert this to a whole number, we can round up to 26 pounds.So the individual has 26 pounds of fat in their body, out of a total weight of 166 pounds.

O 12%
On a dinner of cost $2.25, you want to add 15% to the bill. As a result, your lunch will cost more money overall $2.59.
How to find the calculation?In order to perform a computation, first change the 15% to an actual value. To do this with percentages, just divide the percentage (in this case, 15%) by 100. In terms of a precise mathematical value, the colloquial word "15%" thus becomes 15% / 100% = 0.15.You should next calculate the 15% portion of your $2.25 meal's cost.Always multiply 0.15 by $2.25 to arrive at this figure.
0.15 x $2.25=$0.34.

Here h(x) = [tex]\frac{x-3}{(x-3)(x+3)}[/tex] = [tex]\frac{1}{x+3}[/tex] for x≠3,-3
The given function h is continuous at x=3 then
[tex]\lim_{x \to \3} h(x)= \lim_{n \to \3} h(x) = h(3)[/tex]
=> [tex]\lim_{x \to \3} \frac{1}{x+3} = \lim_{x \to \2} k = k\\[/tex]
=> k = [tex]\frac{1}{3+3} = \frac{1}{6}[/tex]
Hence the value of k is [tex]\frac{1}{6}[/tex].
