The equation tan(55 degree) equals StartFraction 15 Over b EndFraction can be used to find the length of Line segment A C.
Triangle A B C is shown. Angle B C A is a right angle and angle B A C is 55 degrees. The length of A C is b and the length of hypotenuse B C is 15 centimeters.
What is the length of Line segment A C? Round to the nearest tenth.
3.0 cm.
9.8 cm.
10.5 cm.
12.8 cm.
Answers
Answer:
AC is b
[tex]tan55 = \frac{15}{b} [/tex]
15/tan55 = b
tan 55 = 1.428
15/1.428 = 10.5 cm = AC

Two printers can complete a job in 2 hours. The faster printer can do the job, operating alone, in 4 hours. How long would it take the slower printer, operating alone, to do the job?
Answers
Answer:
Let x equal the amount of time required for the second press to complete the job on its own.
The second press then operates at a rate of 1/x of the job per hour.
The two presses work together at a rate of 1/2 of the job per hour.
And the first press operates at a rate of one-sixth of the job per hour.
As a result, our equation to solve is:
1/6+1/x=1/2 multiply each term by 6x x+6=3x subtract x from each side x-x+6=3x-x group like terms together
2x=6 multiply both sides by 2 x=3 the number of hours required for the second press to finish the job
CK
1/6+1/3=1/2
1/6+2/6=1/2\s3/6=1/2
1/2=1/2\salso\s(1/6)*2=1/3\s(1/3)*2=2/3\s2/3+1/3=1 (Only one job)

Most fractions can be simplified into smaller fractions, while some are in it's simplest form. When putting a bit in its simplest form it is much easier to compare to other fractions
What I did first tried to simplify all the factions, starting with 1 1/2.
After looking at 1 1/2, I can see that it is in its simplest form.
Then looking at 1 2/4 I can see that it can be simplified into 1 1/2.
Lastly looking at 1 3/6 I can see that it can be simplified into 1 1/2.

Michelle borrows a total of $2500 in student loans from two lenders. One charges 4.4% simple interest and the other charges
5.7% simple interest. She is not required to pay off the principal or interest for 2 yr. However, at the end of 2 yr, she will owe a
total of $ 246 for the interest from both loans. How much did she borrow from each lender?
Answers
The amount borrowed from the the lender that charges 4.4% interest is $1000.
The amount borrowed from the the lender that charges 5.7% interest is $1500.
What are the linear equations that can be derived from the question?a + b = $2500 equation 1
0.088a + 0.114b = $246 equation 2
Where:
a = amount borrowed from the lender that charges 4.4% interest
b = amount borrowed from the lender that charges 5.7% interest
How much was borrowed from the lender that charges 5.7% interest?Multiply equation 1 by 0.114
0.114a + 0.114b = 285 equation 3
Subtract equation 2 from equation 3
39 = 0.026b
b = $1500
How much was borrowed from the lender that charges 4.4% interest?
Substitute for b in equation 1
a + $1500 = $2500
a = $2500 - $1500
a = $1000

The formula to find the distance between two points is:
d = √[(x2 − x1)² + (y2− y1)²]
distance between (3,4) and (21,4) = 18 cm
distance between (21,4) and (12,16) = 15 cm
distance between (12,16) and (3,4) = 15 cm
height = point in half of the base and the the top point so its (12,16) and (12,4) and the distance between them = 12
triangle perimeter = is the sum all sides
= 48 cm
Triangle area = 0.5 * base * height
