Answer:
S = 32.1 m/s
Step-by-step explanation:
P = 1,500
S = 30
since P is proportional to S², then we must first determine S² = 900
900 / 1,500 = S² / 1,715
(900 x 1,715) / 1,500 = S²
1,543,500 / 1,500 = S²
S² = 1,029
S = √1,029 = 32.08 m/s ≈ 32.1 m/s
In a seminar of 1200 people, 65 percent were women, How many men were in the seminar?
Answer:
420
Step-by-step explanation:
If there were 1200 people, and 65 percent were women, that means the rest of the crowd are men, which is 35 percent. By multiplying 35 percent by the overall population, 1200, (1200*35/100), you'll get 420 men.
Answer:
Step-by-step explanation:
The answer is 420

14. Which set of side lengths can be used to prove the statement below is false?
"In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides."
a) 4 cm, 5 cm, 7 cm
b) 5 cm. 12 cm 13 cm
c) 3 cm, 4 cm, 5 cm
d) 9 cm, 12 cm, 15 cm
Answer:
a) 4 cm, 5 cm, 7 cm
Step-by-step explanation:
The statement "In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides." is only true for triangle rectangles.
To find a counter example, we can try with the options and see which one works as a counterexample:
a) 4 cm, 5 cm, 7 cm
The longest side is 7cm, then the statement says that:
4^2 + 5^2 = 7^2
16 + 25 = 51
while 7^2 = 49
Then for this particular set of sides, the statement is false.
So we already found the counter example, because:
4^2 + 5^2 ≠ 7^2
The only set of side lengths that proves that the statement "In any given triangle, the square of the longest side is equal to the sum of the squares of the two shorter sides." is false is;
Option A; 4 cm, 5 cm, 7 cm
To answer this question, let us look at each option;
Option A; 4 cm, 5 cm, 7 cm
Thus; 4² + 5² = 51 and 7² = 49
Since the sum of the square of the two shorter sides is not equal to the square of the longest side, then this proves the statement is false.
Option B; 5 cm. 12 cm 13 cm
Thus; 5² + 12² = 169 and 13² = 169
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.
Option C; 3 cm, 4 cm, 5 cm
Thus; 3² + 4² = 25 and 5² = 25
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.
Option D; 9 cm, 12 cm, 15 cm
Thus; 9² + 12² = 225 and 15² = 225
Since the sum of the square of the two shorter sides is equal to the square of the longest side, then this proves the statement is true.

A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20. Which statement is true of the box plot of this data set? The box will go from 10 to 12. A line dividing the box will be at 12. The left whisker will go from 4 to 15. The right whisker will go from 12 to 20.
Given:
A data set has a median of 12, an upper quartile of 15, a lower quartile of 10, a minimum of 4, and a maximum of 20.
To find:
The correct statement for the box plot.
Solution:
Lower quartile is 10 and upper quartile is 15, so the box will go from 10 to 15.
Median of the data set is 12, so a line dividing the box will be at 12.
Minimum value is 4 and lower quartile is 10, so the left whisker will go from 4 to 10.
Upper quartile is 15 and maximum value is 20, so the right whisker will go from 15 to 20.
Therefore, the correct option is B.

True or false is a relation in which each y value has only 1 x value
Answer:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
Step-by-step explanation:
The statement is true that a function is a relation in which each y value has ONLY 1 x value.
The reason is very clear that we can not have the repeated x-values (two same x-values).
For example, given the set of the ordered pairs of a relation
{(3, a), (6, b), (6, c)}
As the same x values (x=6) has two different Y values. Hence, the stated relation is not a function.
In order to be a function, a relation must have only 1 x-value for each y-value.
Therefore, the statement is true that a function is a relation in which each y value has ONLY 1 x value.

Answer:
k = 42
Step-by-step explanation:
That's a right angle, indicated by the square. A right angle is 90 degrees.
To find [tex](k+1)[/tex], we need to subtract 47 from 90. 90 - 47 = 43.
To find k, we subtract 1 on both sides. k = 42.

The formula for the volume of a tetrahedron is given as v=sh. Rewrite the
equation so that the height is a function of the area of base and the volume (solve for
the height), then find the height when the area of base is 8 and the volume is 48.
Answer:
h = 6 units
Step-by-step explanation:
The formula for the volume of a tetrahedron is given as :
V = sh
Where
s is area of base and h is height
Put s = 8 and V = 48 to find h as follows :
[tex]h=\dfrac{V}{s}\\\\=\dfrac{48}{8}\\\\h=6[/tex]
So, the height of the tetrahedron is 6 units.

the velocity of a falling body varies directly as the time of flight if the velocity of the falling body at the end of two seconds is 64.4ft/s find the velocity at the end of 5 seconds
Answer:
Step-by-step explanation:
If the velocity of a falling body varies directly as the time of flight, this is expressed as;
v α t
v = kt
k = v/t
If at t = 2secs, v = 64.4ft/s
k = 64/2
k = 32 ft
To get the velocity at the end of 5 secs, we will say;
at t = 5secs v = ?
From the formula;
v = kt
v = 32(5)
v = 160ft/s
Hence the required velocity is 160ft/s

Edna runs at a speed of 9 miles per hour. How many miles per second is her speed?
Answer:
To convert any value in miles per hour to miles per second, just multiply the value in miles per hour by the conversion factor 0.00027777777777778. So, 65 miles per hour times 0.00027777777777778 is equal to 0.01806 miles per second. so the answer is 0.0025

Which number is missing from the following prime factorization expression? 792 = __ x 2 x 2 x 2 x 3 x 11 A. 2 B. 3 C. 5 D. 7
Answer:
3
Step-by-step explanation:
Evaluate 2 x 2 x 2 x 3 x 11 (better written as 2·2·2·3·11, because "x" is a variable name, not a math operator).
2·2·2·3·11 = 8·33 = 264
Then divide 792 by this 264 to find the final factor:
final factor = 792/264 = 3
Then the prime factorization of 792 is 2·2·2·3·3·11
which we obtained by multiplying 2 x 2 x 2 x 3 x 11 by 3.

How do you write this in index form?
The general form is nthroot{a} in index form looks like this: a^(1/n).
Let's rationalize the denominator first.
Doing so, we get (1/2)sqrt{2}.
In index form, the sqrt{2} = 2^(1/2).
We now have (1/2)[2^(1/2)].
Is this clear?
Use the Geometric Mean Theorem and your knowledge of proportions to find the value of x.

If only one-quarter of the earth's surface is not covered by bodies of water, and only one half of that exposed land area is inhabitable for humans (because of poles, deserts, etc.), what fraction of the earth's surface can humans live on?
Answer:
So on the one hand, you could say from these results that 10% of Earth is inhabited by humans. Or you could take a more glass half-empty view and say that 90% of Earth is covered by humans – either populated or connected with an ever-expanding network of roads, train tracks, highways, farms and industrial land.
