Hello.

An exmple would be: 1 3/8 × 3

First, convert the mixed fraction (1 3/8) to an an improper fraction (11/8)

the u will mutlply by the other numbr in the equation that is 3

And, lastly, convert to a mixed fraction (only because the original fraction was in that form)

Have a nice day

I would say its 3/4 because there was only one blue and all together there is 4 now and the probability of picking a purple should be 3 out of 4.

The sides of a triangle are x , x +1 , 2 x -1 and its area is x root of 10 .Find the value of x.
VARVARA [1.3K]


Ok, I'm going to start off saying there is probably an easier way of doing this that's right in front of my face, but I can't see it so I'm going to use Heron's formula, which is A=√[s(s-a)(s-b)(s-c)] where A is the area, s is the semiperimeter (half of the perimeter), and a, b, and c are the side lengths.

Substitute the known values into the formula:

x√10=√{[(x+x+1+2x-1)/2][({x+x+1+2x-1}/2)-x][({x+x+1+2x-1}/2)-(x+1)][({x+x+1+2x-1}/2)-(2x-1)]}

Simplify:

<span>x√10=√{[4x/2][(4x/2)-x][(4x/2)-(x+1)][(4x/2)-(2x-1)]}</span>

<span>x√10=√[2x(2x-x)(2x-x-1)(2x-2x+1)]</span>

<span>x√10=√[2x(x)(x-1)(1)]</span>

<span>x√10=√[2x²(x-1)]</span>

<span>x√10=√(2x³-2x²)</span>

<span>10x²=2x³-2x²</span>

<span>2x³-12x²=0</span>

<span>2x²(x-6)=0</span>

<span>2x²=0 or x-6=0</span>

<span>x=0 or x=6</span>

<span>Therefore, x=6 (you can't have a length of 0).</span>

The student council is selling cookies.They buy the cookies from the store for .55 cents each.They sell the cookies for $1 each.
aleksley [76]

Answer:

The percentage of the markup is 82%

Step-by-step explanation:

In this question, we are asked to calculate the percentage of mark up. This is simply calculating the percentage of the profit margin.

firstly to be able to calculate this percentage, we need to know the value of the profit margin itself.

mathematically, the profit margin is selling price - cost price

From the question, the selling price is $1 while the cost price is 55 cents

The profit margin is thus $1 - 55 cents = 45 cents

We now proceed to calculate the percentage profit

mathematically, that is profit/cost price * 100%

That would be 45 cents/55 cents * 100 = 9/11 * 100% = 81.8 approximately 82%
