Which of the following sets of numbers could represent side
lengths of a right triangle?
Select one:
15 cm, 18 cm. 33 cm
15 cm, 20 cm, 25 cm
15 cm, 16 cm, 17 cm
15 cm, 15 cm, 18 cm
9514 1404 393
Answer:
(b) 15 cm, 20 cm, 25 cm
Step-by-step explanation:
Because you know that the triple (3, 4, 5) is a Pythagorean triple, you know that every multiple of it will also give side lengths of a right triangle. Multiplying that triple by 5 gives (15, 20, 25), matching the 2nd choice on the list.
__
Comments on other choices
You also know that (3, 4, 5) is the only Pythagorean triple that has constant differences, so 15, 16, 17 cannot be a right triangle. (It is very nearly an equilateral triangle.)
A right triangle with same-length sides will have a hypotenuse that is √2 times that length, so no right triangle will have two equal integer legs and an integer hypotenuse.
The lengths 15, 18, 33 form a straight line, not even a triangle.

For those who insist on seeing an equation:
15^2 +20^2 = 225 +400 = 625 = 25^2 . . . 15, 20, 25 will form a right triangle
Is this ordered pair a solution of the equation?
4x - 2y = 6 ( 1 , -1 )
Answer:
yes
Step-by-step explanation:
simply substitute the x and y value coordinates in the equation.
4x-2y=6
4(1)-2(-1)=6
4+2=6
6=6
since it is true that 6=6,yes it is a solution
Simplify 2(5*)
What is the answer
Answer:
the answer is 10 multiply maybe
In a right triangle, a and b are the
lengths of the legs and c is the length of
the hypotenuse. If a = 32 centimeters
and c = 40 centimeters, what is b? If
necessary, round your answer to the
nearest tenth.
Answer:
[tex]b=24\ cm[/tex]
Step-by-step explanation:
Right Triangles
In a right triangle, the relationship between the hypotenuse and the two legs is known as the Pythagora's theorem. If c is the hypotenuse and a and b are the legs, then:
[tex]c^2=a^2+b^2[/tex]
Solving for b:
[tex]b=\sqrt{c^2-a^2}[/tex]
We are given the values c=40 cm, a=32 cm. Calculating b:
[tex]b=\sqrt{40^2-32^2}[/tex]
[tex]b=\sqrt{1600-1024}=\sqrt{576}[/tex]
[tex]\boxed{b=24\ cm}[/tex]

Read the following excerpt from the article "Vision, Voice and the Power of Creation: An Author Speaks Out," by T. A. Barron, and answer the question that follows:
Yet deeper than character, or even place, is another concept: voice. More than any other doorway to the imagination, I find this one the trickiest to open-and the hardest to close. For a character's true voice is heard, its tones, cadences, and ideas are long remembered.
The ancients [people from ancient history] used anima, in fact, to describe breath as well as soul. That is wholly appropriate, for in the breath-the voice-of a character lies its essential spirit. If the writer can truly hear the voice of a character, so will the reader.
Which phrase explicitly states the author's attitude about voice?
Question 4 options:
1)
It is the trickiest door to open.
2)

3)

11. Out of 300 students, 45 are in Calculus, 21 are in Statistics, and 14 are in both.
How many students are in neither Calculus nor Statistics?
a. 234
b. 248
c. 220
d. 286
Answer:
B, 248
Step-by-step explanation:
Out of 45 students in calc and 21 in stats, 14 are repeatedly counted. We can subtract 14 from one group so that this number does not overlap. For example, let us take the calc group:
45-14= 31
31+21 =52 students taking either calc or stats, NOT OVERLAPPED
Everyone else is not taking calc or stats, so 300-52= 248, or B

Answer:
The first column is 5 and the second will be 18 and 2 .
Step-by-step explanation:
You only have to substitute the values into the equation :
let x = 9,
y = 2(9)
y = 18
let y = 10,
10 = 2(x)
x = 5
let x = 1,
y = 2(1)
y = 2

Danna surveyed students in her class She found that 8 earned an A, Six earned a B , 4 earned a C and 2 earned a D on the last science test if she randomly surveyed one more students from the class what is the experimental probability that the student would have earned an A on the test
Answer:
2/5
Step-by-step explanation:
First, find the total number of people she surveyed.
8 + 6 + 4 + 2 = 20.
Next, since 8 of those got an A, the experimental probability would be 8/20.
The last step is to simplify, so
8/20 divided by 4/4 is
2/5

A bicycle was reduced by 20%. The reduced price was £100. What was the original price?
Answer:
£125
Step-by-step explanation:
Let the original price be x
Reduction = 20%
Price after reduction = (100 - 20)% = 80%
80% of x = £ 100
[tex]\frac{80}{100}x = 100\\\\x=100*\frac{100}{80}\\\\[/tex]
x = 125
Original price = £125
Given any two functions f and g, which of the following statements is always true? (1 point)
O If z is in the domain of f. then must be in the domain of f - g.
Olf 2 is in the domain of f and 22 is in the domain of g, then the product, 222, must be in the domain of fg.
O If ac is in the domain of f + g. then I must be in the domain of f and 2 must be in the domain of 9
O fa is not in the domain of then a is not in the domain of g
Answer:
cccccc
Step-by-step explanation:
Given two functions f and g, we want to see which statement is always true.
The only true statement is the third one:
"If a is in the domain of f + g. then I must be in the domain of f and it must be in the domain of g"
So what we can do, is try to find counterexamples for the given statements, if we can't, then the statements are true.
Note that the statements are really badly written, so I will complete them in a way that makes sense.
a) "If z is in the domain of f. then must be in the domain of f - g"
False, if z is not in the domain of g, then we can't define:
(f - g)(z)
This would happen if:
g = 1/(x - z)
b) "lf 2 is in the domain of f and 22 is in the domain of g, then the product, 222, must be in the domain of fg"
False, lets replace:
2 = z
22 = k
And let's say that:
f(x) = 1/(x - z*k)
g(x) = x
Then we have:
f*g(x) = x/(x - z*k)
Clearly, z*k (or 222 as you wrote it) is not on the domain.
c) "If a is in the domain of f + g. then I must be in the domain of f and it must be in the domain of g"
True, it only can be on the domain of the sum of the two functions if it belongs to the domain of each one.
d) "if a is not in the domain of (f + g) then a is not in the domain of g"
This is false, because a could be in the domain of g and not be in the domain of f.
Then the only true statement is the third one.
