If [tex]\frac{a+b}{3} =\frac{b+c}{6} =\frac{c+a}{5}[/tex] then prove that: [tex]\frac{a+b+c}{a} =7[/tex]
Answers
Answer:
[tex]\dfrac{a+b+c}{a} =7[/tex]
Step-by-step explanation:
Given :-
[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}[/tex]And we need to prove that ,
[tex]\dfrac{a+b+c}{a} =7[/tex]So let us assume that ,
[tex]\dfrac{a+b}{3} =\dfrac{b+c}{6} =\dfrac{c+a}{5}=k[/tex]
Where k is a constant . Now equate each of the three terms separately to k . Therefore we have ,
[tex]\dfrac{a+b}{3}=k[/tex][tex]\implies a + b = 3k \quad \dots (i) [/tex]
Similarly we can say that ,
[tex]\implies c + b = 6k \quad \dots (ii)[/tex]
[tex]\implies a + c = 5k\quad \dots (iii) [/tex]
Subtracting (i) and (ii) :-
[tex]\implies a - c = -3k \quad \dots (iv) [/tex]Adding (iv) and (iii) :-
[tex]\implies 2c = 4k [/tex]
[tex]\implies \boxed{c = 4k }[/tex]
Put this is (ii) :-
[tex]\implies b +4k = 6k [/tex]
[tex]\implies \boxed{b= 2k }[/tex]
Similarly we will get ,
[tex]\implies \boxed{a = k }[/tex]
Proving the given equation :-
[tex]\implies \dfrac{a+b+c}{a} \\\\\implies \dfrac{k+2k+4k}{k} \\\\\implies \dfrac{7k}{k}=\boxed{\red{ 7}}[/tex]
Hence proved !

Mr.Li bought a memory card for $138.89 including tax.The card had a sticker price of $129.20.What percent sales tax did he pay.
Answers
Answer:
7.5%
Step-by-step explanation:
Cost of memory card including tax = $138.89
Cost of memory card only = $129.20.
Cost of tax on memory card = Cost of memory card including tax - Cost of memory card only
= $138.89 - $129.20
= $9.69
Cost of tax on memory card = $9.69
What percent sales tax did he pay.
Percent of tax = Cost of tax on memory card / Cost of memory card only
= $9.69 / $129.20 × 100
= 0.075 × 100
= 7.5%
Percent of tax = 7.5%

[tex] \sqrt[2]{24 + 12} \: \times \sqrt{ {6}^{4} } \times {5}^{2} [/tex]
Answers
Answer:
root 24+12 is root 36 which is equal to 6
4 root of 6 is 36 the power of 2 which is equal to 36
5 the power of 2 is 25
then when we multiple 6x36x25
it's 5400
Answer:
Answer = 1080
Step-by-step explanation:
Hey there!
Here's the initial equation:
[tex]\sqrt{24+12} * \sqrt{6^4 * 5^2}[/tex]
What I'll do now is sum what's in the left root.
[tex]\sqrt{36} * \sqrt{6^4 * 5^2}[/tex]
Since [tex]\sqrt{36}[/tex] = 6, we get this equation:
[tex]6 * \sqrt{6^4 * 5^2}[/tex]
Now: You can see that the five is elevated to the second. Since it is a square root, you can just pop it out:
6 * [tex]5\sqrt{6^4}[/tex]
6 * 5 = 30, so here's what you got:
[tex]30\sqrt{6^4}[/tex]
At this point you should see that:
[tex]6^4[/tex] = 6 * 6 * 6 * 6
6 * 6 * 6 * 6 = 36 * 6 * 6
36 * 6 * 6 = 36 * 36
36 * 36 = 36²
Now you have this:
[tex]30\sqrt[2]{36^2}[/tex]
Since it is a square root and a square number, you can do just as with the five: Pop it out! (When you take numbers out of the root they multiply, they do not add. Never forget that ;).
30 * 36 = 1080
Answer = 1080

An electrician needs 3/8 of a roll of electrical wire to wire each room in a house. How many rooms can he wire with 2 1/4 rolls of wire? Write your answer as a fraction or as a whole or mixed number.
Answers
Answer: 6 rooms
Step-by-step explanation:
3/8 rolls of wire are needed to wire a room in a house. If there are a total of 2¹/₄ rolls of wires, the number of rooms that could be wired is:
First convert to an improper fraction:
2¹/₄ = 9/4 rolls of wire
Total number of rooms that can be wired are:
= Total amount of wire available / Wires per room
= 9/4 ÷ 3/8
= 9/4 * 8/3
= 72 / 12
= 6 rooms

Positive, the graph will open up and have a minimum
Negative, the gaph will open down and have a maximum
Answer:
opens up and has a minimum
Step-by-step explanation:
Provided a is not 0, y=ax^2+bx+c will be a parabola.
The parabola will open up and have a minimum if a is positive.
The parabola will open down and have a maximum if a is negative.
Since 1/2 is positive, then your parabola opens up and has a minimum.

question is 'what is 5.8% of 2375'
'what' means assign a variable
'is' means an equal sign
'of' means to multiply
p = .058 x 2375
p = 137.75
*You could do the following: p = 5.8 x 2375 and get 13775 but you have to remember to move the decimal point two places to the left
