If there are 2.54 cm in 1 inch how long is a 36 inch long measuring stick in cm
Answer: The answer is 91.44 centimeters/cm
Step-by-step explanation:
2.54*36= 91.44 centimeters/cm
A 36-inch long measuring stick is equivalent to 91.44 cm.
To convert inches to centimeters, we can use the conversion factor:
1 inch = 2.54 cm
To find out the length of a 36-inch measuring stick in centimeters,
we multiply the length in inches by the conversion factor:
36 inches x 2.54 cm/inch
= 91.44 cm
Therefore, a 36-inch long measuring stick is equivalent to 91.44 cm.

Answer: Approximately 1336.50301206033 square cm
=======================================================
Explanation:
If we know the three side lengths of a triangle, then we can use Heron's formula to get the area
Heron's formula is
[tex]A = \sqrt{S(S-a)(S-b)(S-c)[/tex]
with S being the semiperimeter, or half the perimeter, so [tex]S = \frac{a+b+c}{2}[/tex]. We add up all three sides and divide by 2.
----------------
The smaller triangle has side lengths of a = 19, b = 40, c = 41. So we get a semiperimeter of S = (a+b+c)/2 = (19+40+41)/2 = 50
Plug this along with the a,b,c values to get an area of...
[tex]A = \sqrt{S(S-a)(S-b)(S-c)}\\\\A = \sqrt{50(50-19)(50-40)(50-41)}\\\\A = \sqrt{139500}\\\\A \approx 373.496987939661\\\\[/tex]
which is approximate
-----------------
Do the same for the larger triangle as well
S = (a+b+c)/2 = (19+180+181)/2 = 190
[tex]A = \sqrt{S(S-a)(S-b)(S-c)}\\\\A = \sqrt{190(190-19)(190-180)(190-181)}\\\\A = \sqrt{2924100}\\\\A = 1710\\\\[/tex]
Interestingly enough, we get an exact area value this time as opposed to some approximation.
-----------------
The difference between the two results is the area of the shaded region
1710 - 373.496987939661 = 1336.50301206033
This is approximate since the first result was approximate.
Answer:
K = 1710 cm^2 - K = 373.497 cm^2 = 1337 cm^2
Step-by-step explanation:
Why don't you just look for the whole area and deduct the non-shaded area?

Use fundamental identities and/or the complementary angle theorem to find the exact value of the given expression. Do not use a calculator. sec234°−tan234°
Answer:
1Step-by-step explanation:
Given the expression sec²34°−tan²34°, to get the exact value using the fundamental identities and/or the complementary angle theorem, we will apply the trigonometry identity
From sin²θ+cos²θ = 1
Divide both sides of the expression by cos²θ
sin²θ/cos²θ+cos²θ/cos²θ = 1/cos²θ
tan²θ+1 =sec²θ
Since sec²θ= tan²θ+1, hence sec²34°= tan²34°+1... 1
Substituting equation 1 into the expression given in question we will have;
sec²34°−tan²34°
= (tan²34°+1)-tan²34°
collect like terms
= tan²34°-tan²34°+1
= 1
Hence the exact value of the expression sec²34°−tan²34° is 1
Mr. and Mrs. Tournas know that their son will attend a college, in 14 years, that they estimate to cost approximately $250,000. How much should they deposit now if they assume that they can earn 8.5% compounded annually?
a) $72,083.41
b) $76,055.32
c) $75,450.20
d) $79,785.45
Answer: D
Step-by-step explanation:
We will try it to determine how much the need to save using the exponential function. In an exponential function,we need the start up amount and the common difference.
We know that the common difference is is 1.085 because if they will earn 8.5% interest plus 100% .
So 1.085 raised to the number of years times a number has to equal 250,000
x * 1.085^14 = 250,000 now solve for x
3.13340357495x = 250,000
x = 79785.44544 Rounded to the nearest cent is $79785.45

A ream of a certain brand of paper weighs about 3.225 pounds. A ream contains 500 sheets of paper. How much does a sheet of paper weigh?
Answer:
A single sheet of paper should weigh: 0.00645 pound or [tex]6.45*10^{-3}[/tex] (in scientific notation)
Step-by-step explanation:
Divide 3.225 (the weight of the ream of paper) by 500 (the amount of paper in a ream).
If you need the scientific notation form, simply move the decimal point/place right or left until you end up with a whole number that is between 1 and 10 (in this case, 3 times to the right), then determine what power of 10 it should be, depending on the number of times you moved the decimal place (in this case, the power is -3).
The power/exponent is determined by the direction you have to move your decimal point, right=negative and left=positive. For example, if you started off with the number 6450, you would move the decimal point 3 times to the left and your power would be positive 3, which results in [tex]6.45*10^{3}[/tex].

Factoring expressions 3x+ 12
Answer:
3(x + 4)
Step-by-step explanation:
Factor out a 3 from both terms, since 3 and 12 are both divisible by 3.
3x + 12
3(x + 4)
So, the factored expression is 3(x + 4)
Answer: 3(x+4)
Step-by-step explanation:
Hii! Do you need to factor the expression 3x+12? No problem! :)
Note that, both 3x and 12 have something in common. This "something" is known as the greatest common factor, or g.c.f.
The g.c.f. of 3x and 12 is 3, so we divide both 3x and 12 by 3
x+4; next we put parentheses around x+4.
(x+4)
Now we put 3 outside the parentheses.

Micheal just moved here from Chicago. Micheal has red hair, therefore people from Chicago have red hair
Is this Inductive reasoning or Deductive reasoning?
Answer:
inductive
Step-by-step explanation:
Inductive reasoning is based on generalization, and making conclusions without hard evidence. If Micheal has red hair and is from Chicago, inductive reasoning draws the conclusion that everyone in Chicago has red hair. Deductive reasoning would be predicting that everyone in Chicago has red hair, and then testing it to see if you are right.
