Answer:

11,500

Step-by-step explanation:

cost price of a book (CP) = 10000

profit percent = 15%

selling price of a book (SP) = ?

SP = CP + profit% of CP

=10000 + 15 / 100 * 10000

=1000000 + 150000/100

=1150000/100

=11500

Therefore, the book will cost 11,500

Here,
We have,
Cost price of a book (CP) = N10,000
Profit percent (p%)= 15%
Now,
Using profit percent formula we get,
P% = (Sp-Cp)/ Cp*100
15 = (Sp-10,000)/10,000*100.
15*10000=100Sp-1000000
150000+1000000=100Sp
1150000/100=Sp
Sp=11500

Hence,
A book should be sold at 11500

Determine whether or not there is a congruence between △abc and △def. if there is such a congruence, then give the reason for it

Andru [333]

There is no congruence between the triangles based on the given information. In general, two sides and an angle not between them are insufficient to specify the triangle completely. In this case, the angles that are congruent are adjacent to non-corresponding sides, so even if SSA correspondence were sufficient to ensure congruence, it would not be sufficient in this case.

The appropriate choice is

... none

Can someone help me, I don’t get this

I'll break it down for you. Here are the main points:

-has 2 large servings

-made from 9 pints

-x represents how many pints

-y represents how many servings

Now that we know this we can find what each serving comes out to be for example:

$\frac{9}{2\\}$ =4.5 or 4 $\frac{1}{2}$

So for each serving it will come out to be 4.5 pints.

Now that we know this we can figure out the slope to find what the equation which is for example the slope for this equation would be rise over run for example:

$\frac{rise}{run}$ = $\frac{1}{4.5}$ = $\frac{2}{9}$ when simplified.
