Store A has the best deal.
Lets say shirts are $11 a piece. If you buy 3 that is $33. If you take 25% off, you save $8.25. B only saves $5.50 and C only saves $3.30

So we are assuming that the three shirts have equal price. Let the price of one shirt be a.

In store A:

the cost is (a+a+a) -(25/100)a=3a-0.25a=2.75a

In store B: 

the cost is : a+a+50/100 a =a+a+0.5a=2.5a


In store C:

the cost is
[a-(10/100)a]+[a-(10/100)a]+[a-(10/100)a]=[a-0.1a]+[a-0.1a]+[a-0.1a]
=0.9a+0.9a+0.9a= 2.7a


thus the cost of buying the shirts from stores A, B and C is: 

2.75a, 2.5 a and 2.7 a respectively.

the best deal, is buying from store B, where the cost is the lowest: 2.5a.

Answer: store B

PRECALC QUESTION! Convert the polar representation of this complex number into its standard form: z = 2(cos 11pi/6+ i sin 11pi/6
Tanzania [10]
\bf z=2\left[ cos\left( \frac{11\pi }{6} \right) + i\ sin\left( \frac{11\pi }{6} \right) \right]\qquad 
\begin{cases}
r=2\\
\theta=\frac{11\pi }{6}\\
-----\\
a=x=rcos(\theta)\\
b=y=rsin(\theta)
\end{cases}\implies a+bi
\\\\\\
2cos\left( \frac{11\pi }{6} \right)+2sin\left( \frac{11\pi }{6} \right)\ i\implies 2\cdot \cfrac{\sqrt{3}}{2}+2\cdot \cfrac{-1}{2}\ i\implies \sqrt{3}-1i
\\\\\\
\boxed{\sqrt{3}-i}

The hypotenuse of a right triangle is 26 mm. One leg of the right triangle is 10 mm. What is the length of the other leg? (4 poi
PIT_PIT [208]

Answer:

24 mm

Step-by-step explanation:

Since it is a right triangle, we can use Pythagorean theorem

a^2+b^2=c^2

where a and b are the legs, and c is the hypotenuse.

We know one of the legs is 10, and the hypotenuse is 26, so we can substitute 10 in for a, and 26 in for c.

10^2+b^2=26^2

Solve the exponents

100+b^2=676

Now, solve for b. To do this, get b by itself.

First, subtract 100 from both sides

100-100+b^2=676-100

b^2=576

Take the square root of both sides

\sqrt{b^2}=\sqrt{576}

b=24

So, the other leg is 24 mm

It is possible to multiply a 3 x 5 matrix and a 3 x 5 matrix.<br> O True<br> O False
oksian1 [2.3K]

Answer:

False

Step-by-step explanation:

In order to perform matrix multiplication, the number of columns in the first matrix must be the same as the number of rows in the second matrix.

In this case, the number of columns in the first matrix is 5 and the number of rows in the second column is 3 therefore they aren't the same value, hence, cannot be multiplied
