Carlos can print a document on apricot printer which the speed is 8 in 4.5 minutes how long would it take him to print the same document on a sure-fire printer which the speed is 12
Answers
The surefire printer has a speed of 12.
The surefire is faster than the apricot printer, so it wll take less time to print a document.
The apricot printer takes 4.5 minutes.
Therefore by proportion, the surefire printer takes
(8/12)*4.5 = 3 minutes.
Answer: 3 minutes

a right triangle has a base that measures 39 inches and a height that measures 80 inches what is the length of the hypotense
Answers
The Pythagorean Theorem states the a^2 + b^2 = c^2. If we plug the numbers into this equation, we will find the length of the hypotenuse.
39^2 + 80^2 = c^2
1521 + 6400 = c^2
7921 = c^2
We have c squared now, but we want to know how much c is equal to. The square root of c^2 will be our answer.
89 = c
The length of the hypotenuse of a right triangle with legs that measure 39 and 80 inches is 89 inches.

A line has a slope of 3/5. It passes through (3,5) and (x,9). What is the value of x?
Answers
Final answer:
The value of x for the line with a slope of 3/5 that passes through (3,5) and (x,9) is 9 2/3 or 9.67 when expressed as a decimal.
Explanation:
To find the value of x for the point (x, 9) on a line with a slope of 3/5, we can use the slope formula which is (change in y) / (change in x) = slope. We know two points on this line, (3, 5) and (x, 9).
First, calculate the change in y which is 9 - 5 = 4. Then, use the slope of 3/5 and set it equal to the change in y (which is 4) over the change in x (which is x - 3):
3/5 = 4 / (x - 3)
To find x, we cross-multiply:
3 x (x - 3) = 5 x 4
3x - 9 = 20
Add 9 to both sides: 3x = 29
Divide both sides by 3: x = 29/3
Therefore, x = 9 2/3 or 9.67 when expressed as a decimal.
This calculation shows the x-coordinate for the point where the line passes through y-coordinate 9.

Answer:
ummm its called a lender since that person is "lending" you something
Step-by-step explanation:
A person or company that allows others to borrow money is called a "lender".
What is a Lender?A lender is a person, a group (public or private), or a financial organization that makes cash accessible to a person or business with the expectation of repayment. Payment of any interest or fees will be included in the repayment.
Repayment might take place in installments (such as a monthly mortgage payment) or as a flat amount. A mortgage is one of the largest loans that individuals obtain from lenders.
The loan duration varies depending on the type of debt. While some loans are for 1-2 years, the majority are for 6-12 months.
Thus, a person or company that allows others to borrow money is called a "lender".

If the temperature after 1 hour is 81 degrees celcius, what are two possible original temperatures? What is the difference between the possible original temperatures?

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]
It is given that:
A scientist finds the temperature of a sample at the beginning of an experiment is t degrees Celcius.
After 1 hour, the temperature is t² degrees Celcius. If the temperature after 1 hour is 81 degrees Celcius.
From the question:
t² = 81
Taking square root on both sides:
t = ±√81
t = ±9
t = 9 degrees Celcius
Or
t = -9 degrees Celcius
The difference between the temperature = (9) - (-9) = 18 degrees Celcius
Thus, the two possible original temperatures are 9 and - 9 degrees Celcius and the difference between the temperature is 18 degrees Celcius.

A map of square piece of property is drawn at a scale of 1 : 500. If a side of the property on the map is 16 cm, what is the property's actual area?
Answers
Answer:
[tex]\text{Actual area of property}}=6400\text{ m}^2[/tex]
Step-by-step explanation:
Let x represent the actual side of square property.
We have been given that a map of square piece of property is drawn at a scale of 1 : 500.
We will use proportions to solve for our given problem.
[tex]\frac{\text{Actual length}}{\text{Map length}}=\frac{500}{1}[/tex]
[tex]\frac{x}{16\text{ cm}}=\frac{500}{1}[/tex]
[tex]\frac{x}{16\text{ cm}}*16\text{ cm}=500*16\text{ cm}}[/tex]
[tex]x=8000\text{ cm}[/tex]
[tex]x=80\text{ m}[/tex]
We know that area of a square is square of its side length.
[tex]\text{Actual area of property}}=(80\text{ m})^2[/tex]
[tex]\text{Actual area of property}}=6400\text{ m}^2[/tex]
Therefore, the actual area of property is 6400 square meters.
