Answer:
7 1/14
Step-by-step explanation:
198÷28 = 7.blablabla
Therefore, 7 is the integer
so you take 7 and multiply it by 28 = 196
198 - 196 = 2
Therefore, 2 is the remainder
The format for mixed numbers is Integer (remainder/denominator)
so the mixed fraction is 7 2/28
2/28 can be reduced to 1/14
Therefore the final answer is 7 1/14
The current, I, varies inversely to the resistance, R. If the current is 250 milliamperes
when the resistance is 5 ohms, find the current when the resistance is 20 ohms.
a) 124.5 milliamperes
b) 50 milliamperes
C)62.5 milliamperes
d) 1250 milliamperes
Answer:
C
Step-by-step explanation:
First find the voltage which is current times resistance. Convert milliamperes to amperes. Divide 250/1000 because amperes are 1000 times smaller. That results in 0.25. So multiply 0.25 A by 5 ohms. That is 1.25. Now divide 20 by 1.25 which is 0.0625. Convert that to millamperes by multiplying by 1000. That gives you 62.5 millamperes.

How many strings of five English letters that start with two consecutive vowels (A,E,I,O, or U) have no repeated letters
Answer:
242880
Step-by-step explanation:
In the English alphabet, we have 5 vowels. To form a string of 5 English letters in which it starts with two consecutive vowels; then we have the following.
In the first space, 5 vowels are possible.
in the second space, 4 vowels are possible since there is no room for repetition of letters.
Now, the total number of ways of assigning two distinct vowels in the first two spaces = 5 × 4 = 20
From the question, since it is said that the letter starts with two consecutive vowels, it implies that starting from the third letter, it can be filled with all the remaining alphabet, be it a vowel or consonant.
Thus, the remaining alphabet = 26 - 2 = 24 alphabets to fill the 3 remaining spaces, which can be achieved in 24P3 ways.
P(24,3) = 24!/(24-3)!
P(24,3) = 24!/21!
P(24,3) = 24 × 23 × 22 × 21! / 21!
P(24,3) = 24 × 23 × 22
P(24,3) = 12144 ways
Thus, the total number of strings of five English letters that start with two consecutive vowels without having repeated letters is:
= 5 × 4 × 24 × 23 × 22
= 242880
5 4 24 23 22
what do we mean by "Elegance Of Mathematical Proof"?
Answer:
Mathematical beauty is the aesthetic pleasure typically derived from the abstractness, purity, simplicity, depth or orderliness of mathematics.[1] Mathematicians often express this pleasure by describing mathematics (or, at least, some aspect of mathematics) as beautiful. They might also describe mathematics as an art form (e.g., a position taken by G. H. Hardy[2]) or, at a minimum, as a creative activity. Comparisons are often made with music and poetry.

Write a system of linear equations that represents this situation.
Answer:
x + 5y = 22.45
x + 7y = 25.45
Step-by-step explanation:
Given:
Customer A oil tank size = 5 quart
Customer B oil tank size = 7 quart
Total cost for A = $22.45
Total cost for B = $25.45
Find:
Equation

Solve for a
Thanks
Answer:
a = (u-b)/k
Step-by-step explanation:
to solve for a means to leave a on its own
u = b + ak
let’s subtract b from both sides to leave a on its own
u - b = ak
to leave a on its own we’ll divide both sides by k
a = (u-b)/k

jack is thinking of two whole numbers
the sum of the number is 13
the difference between the numbers is 1
what is the product of the numbers
Answer:
Their product is 42
Step-by-step explanation:
Let the numbers be A and B
Such that:
[tex]A + B = 13[/tex]
[tex]A - B = 1[/tex]
Required
Determine A * B
Add both equations together:
[tex]A + A + B - B = 13 + 1[/tex]
[tex]2A = 14[/tex]
Solve for A
[tex]A = 7[/tex]
Substitute 7 for A in the second equation
[tex]7 - B = 1[/tex]
Make B the subject
[tex]B = 7 - 1[/tex]
[tex]B = 6[/tex]
Hence,
A = 7 and B = 6
So:
[tex]A * B = 7 * 6[/tex]
[tex]A * B = 42[/tex]
The product of the two numbers will be 42.
Let the two numbers be A and B
A + B = 13
A - B = 1
A = 1 + B.
Therefore, since A + B = 13, then (1 + B) + B = 13
1 + 2B = 13
2B = 13 - 1
2B = 12
B = 6
A = 6 + 1 = 7
Since the numbers are 6 and 7, then multiplying them is 42.

For what values of k does the function y = cos(kt) satisfy the differential equation 81y'' = â16y? (Enter your answers as a comma-separated list.)K = ______
Answer:
16/81
Step-by-step explanation:
Given the expression, 81y'' = -16y where y = coskt,
We want to know the value of k that satisfies the expression
y' = -ksinkt
y" = -k²coskt
Substitute y and y" into the expression given;
81y'' = -16y
81(-k²coskt) = -16(kcoskt)
-81k = -16
Divide both sides by -81
-81k/-81 = -16/-81
k = 16/81
Hence the value of k is 16/81

Which postulate or theorem can be used for...
Answer:
A. SSS
Step-by-step explanation:
∆ABC has shown above has two given sides indicated, AB and AC, which are congruent to the corresponding two sides l, DC and DB, of ∆DCB.
Also, their third side is also congruent since they share a common side, side BC.
This means that the three sides of ∆ABC is congruent to the three corresponding sides of ∆DCB.
Therefore, ∆ABC is congruent to ∆DCB by the Side-Side-Side Congruence Theorem, which holds that of the three sides of one triangle is congruent to the three corresponding sides of another, then both ∆s are congruent.
