You could give all of the fractions a common denominator. You could also solve each of them (1/2=0.5) to see their value and order them through the value.

Five less than twice the value of a number is equal to three times the quantity of
MissTica

Answer:

These types of questions are not daunting if you break it down. First look at  "Five less than twice the value of a number."

"Twice the value of a number" is simply 2x.

"Five less" is simply -5, so for the first part we have (2x-5)

Next, analyze the second part. "Three times the quantity of four more than one half the number."

Looking at "Three times the quantity" simply means "3 times something".

"the quantity of four more than one half the number" is 4 + "one half the number" or 4 + (1/2)x.

So the second part is simply 3(4+x/2).

Finally we finish the entire equation, (2x-5) = 3(4+x/2) then solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x=34

Checking the left side, (2x-5) = 2(34) - 5 = 63.

Checking the right side, 3(4+(34/2)) = 3(4+17) = 3(21) = 63.

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive rea
Orlov [11]

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that \sqrt{p(1-p}\leq \frac{1}{2}

<u><em>Step(ii):</em></u>-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }

         0.02 = \frac{\frac{1}{2}  }{\sqrt{n} }

        \sqrt{n} =\frac{1}{2 X0.02}

        √n = 25

squaring on both sides, we get

       n = 625

A triangle has an area of 35 square inches. the length of one of the sides it 10 inches. what is the length of the perimeter? in
Serggg [28]
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4

QUESTION 4 of 10: You have budgeted $850 per month for rent. Your landlord has just informed you that your rent is being raised
puteri [66]

Answer:

We conclude that will  rent be at the end of this year 937.125$.

Step-by-step explanation:

We know that we have budgeted $850 per month for rent. Your landlord has just informed you that your rent is being raised by 5% now and another 5% on December 1st.

We calculate

\frac{850}{100}=8.5\\\\5\cdot 8.5=42.5\\\\850+42.5=892.5\\

now, we get

\frac{892.5}{100}=8.925\\\\5\cdot 8.925=44.625\\\\892.5+44.625=937.125\\

We conclude that will  rent be at the end of this year 937.125$.
