Answer:
70 , 84 , 105
Step-by-step explanation:
sum their ages , 10 + 12 + 15 = 37
divide the amount by this sum to find the value of one part of the ratio.
259 ÷ 37 = 7 ← value of 1 part of the ratio , then
10 parts = 10 × 7 = 70 euros ← Tom's share
12 parts = 12 × 7 = 84 euros ← Mary's share
15 parts = 15 × 7 = 105 euros ← Bill's share
Answer:
The answer is A
Step-by-step explanation:
Just did the problem.
The poll has an error of 600 votes. The total number of votes including the error shown by the poll is 15600 or 14400.
Statement B is correct.
<h3>What is the percentage?</h3>
A percentage can be defined as a relative number that shows the hundredth part of the given number. The percentage is represented by the sign "%".
Given that In the next election, 15,000 people will actually vote for Candidate A. A poll has a percent error of 4%.
The error can be calculated as given below.
The poll has an error of 600 votes. This will affect the total number of votes in the election.
The total number of votes V including errors are given as,

<em />
or
Hence we can conclude that the total number of votes including the error shown by the poll is 15600 or 14400. Statement B is correct.

The answer to the above equation is 3
Step-by-step explanation:
(a-b)³+(b-c)³+(c-a)³: (a-b)(b-c)(c-a)
Let us consider (a−b)= x, (b−c)= y and (c−a)= z.
Hence, It is obvious that:
x+y+z =0 ∵all the terms gets cancelled out
⇒We must remember the algebraic formula
x³+y³+z³−3xyz= (x+y+z) (x²+y²+z²-xy-xz-yz)
Since x+y+z=0 ⇒Whole “(x+y+z) (x²+y²+z²-xy-xz-yz)
” term becomes 0
x³+y³+z³−3xyz =0
Alternatively, x³+y³+z³= 3xyz
Now putting the value of x, y, z in the original equation
(a-b)³+(b-c)³+(c-a)³ can be written as 3(a-b)(b-c)(c-a) since (a−b)= x, (b−c)= y and (c−a)= z.
3(a-b)(b-c)(c-a): (a-b)(b-c)(c-a)
= 3 ∵Common factor (a-b)(b-c)(c-a) gets cancelled out
Answer to the above question is 3
Answer:
y=-1/5x+6
Step-by-step explanation:
y-b=m(x-a)
×5) y-7=-1/5(x--5) (×5
5y-35=-1(x+5)
5y-35=-x-5
5y=-x+30
y=-1/5x+6
