Answer:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
Any number that can be written as a fraction with integers is called a rational number . For example, 17 and −34 are rational numbers

A hot air balloon was flying at an altitude of 300 meters when the pilot decided to land by descending at a rate of 2 meters per second. For which of these rules does y represent the altitude of the hot air balloon, if x represents the number of seconds since the pilot started her landing?
Answer:
The answer is "150 seconds".
Step-by-step explanation:
[tex]\to distance = 300 \ meter\\\\\to speed = 2 \ \frac{m}{s} \\\\\ formula: \\\\ \bold{speed = \frac{distance}{time}}\\\\[/tex]
[tex]time= \frac{distance}{speed}\\\\[/tex]

Find the slope of a line PERPENDICULAR TO LM:
L(3,-5), M(-4, -1)
Answer:
[tex]\frac{7}4[/tex]
Step-by-step explanation:
First, we need to find the slope, which is defined as the change in y over the change in x:
[tex]\frac{-5-(-1)}{3-(-4)} = \frac{-4}{7}[/tex]
To find a slope that's perpendicular to that, we just take the negative reciprocal of that slope, which is [tex]\frac{7}4[/tex].

x =
Step-by-step explanation:
x+55+80=180(sum of triangle)
or,x+135=180
or,x=180-135
or,x=45
Therefore,x=45°
The value of X or angle C is 45 degrees.
Given:
Two angles of triangle ABC are 80 degrees and 55 degrees.
It is required to find the value third angle X of the triangle.
The sum of three angles of a triangle is 180°.
So, the third angle, X, can be calculated as,
[tex]80+55+x=180\\135+x=180\\x=45^{\circ}[/tex]
Thus, we can conclude that the value of X is 45°.

1-cos2a/1+cosa if 1/3 how much sin²a
Answer:
(1-cos2A) /(1+cos2A) =tan²A
Proof:
We know that,
cos(A+B) =cosA.cosB-sinA.sinB
=>cos2A=cos(A+A)
=>cos2A=cosA.cosA - sinA.sinA
=>cos2A=cos²A-sin²A
=>cos2A=(cos²A-sin²A)/(cos²A+sin²A
Since {cos²A+sin²A=1}
Divide the numerator & the denominator by (cos²A) to get,
cos2A = {(cos²A-sin²A) ÷cos²A} / {(cos²A+sin²A) ÷cos²A}
cos2A ={(1-tan²A)/(1+tan²A)}
Then,
1-cos2A = 1-[{(1–tan²A)/(1+tan²A)}]
1-cos2A =(1+tan²A-1+tan²A)/(1+tan²A)
1-cos2A=(2tan²A)/(1+tan²A)
And now.......
1+cos2A=1+[{(1-tan²A)/(1+tan²A)}]
1+cos2A={1+tan²A+1-tan²A}/{1+tan²A}
1+cos2A=2/(1+tan²A)
So now,
(1-cos2A)/(1+cos2A)= {2tan²A/(1+tan²A)}÷{2/(1+tan²A)}
={(2tan²A)(1+tan²A)}÷{2(1+tan²A)}
=tan²A

There are 15 clowns in a circus. Each clown has to act either happy or sad. Twelve of the clowns have red noses. Each of the seven happy clowns has a red nose. Five of the sad clowns have red noses. How many clowns have to act sad and do not have a red nose?
Answer:
3
Step-by-step explanation:
Each of the seven happy clowns has a red nose.This means there are (15-7) 8 sad clowns.
Five of the sad clowns have red noses.This means out of 8 sad clowns, 5 have red noses. So the clowns that have to act sad and have red noses are (8-5) 3.

what is the mathematical sentence of "the length of wooden frame is 1foot longer than it's width and it's area is equal to 12ft²" can you translate it into quadratic equation in terms of "x"?
Answer:
x²+x+12 = 0
Step-by-step explanation:
Area if the wooden frame = ,Length ×Width
A = LW
If the length of wooden frame is 1foot longer than it's width, then;
L = W+1
Given
A = 12ft²
Substitute the derived and given parameters into the formula to have;
P = (W+1)W
12 = (W+1)W
Open the parentheses
12 = W²+W
Subtract 12 from both sides
12-12 = W²+W -12
0 = W²+W-12
Rearrange
W²+W-12 = 0
If W = x
The quadratic equation becomes:
x²+x+12 = 0

George wants to increase the amount of push-ups that he can do each day by 2. He is already able to do 14 push-ups. The amount of push-ups George wants to do each day is given by the linear function f(x) = 2x + 12. Which explicit rule is equivalent to this linear function?
Answer:
Explicit rule used is: f(n) = f(1) + (n - 1)d
Step-by-step explanation:
We are told he currently does 14 push ups per day.
Now, he wants to increase the push ups by 2 per day.
Now, the first term in the sequence of push ups is 14 while the constant difference is 2.
Now, the explicit rule to be used here is arithmetic progression whereby;
f(n) = f(1) + (n - 1)d
Where;
f(1) is first number in the sequence
d is constant difference
n is number of days
Thus, plugging in our values from the question, we have;
f(n) = 14 + (n - 1)2
f(n) = 14 + 2n - 2
f(n) = 2n + 12
This tallies with the linear function given in the question.
Thus; the explicit rule used here is;
f(n) = f(1) + (n - 1)d

A. p = 3
B. p = -3
C. p = 6
D. p = -6
Or none of the above
Answer:
none of the above
Step-by-step explanation:
p^3 = 125

If the m∠A is less than 90°, then ∠A is an acute angle. M∠A=75° . What can you logically conclude using the Law of Detachment? ∠A is acute. ∠A is acute. ∠A is right. ∠A is right. ∠A is obtuse. ∠A is obtuse. Not enough information. Not enough information.
Answer:
∠A is acute. ∠A is acute.
Step-by-step explanation:
Given that
m∠A is lower than 90°
So, it is an acute angle
And, M∠A=75°
The acute angle is the angle that measures between 0 degrees and 90 degrees on the other case the obtuse angle should be more than 90 degrees till 180 degrees
So as per the law of detachment the first option is correct and the same is to be considered
