Sales An apparel shop sells skirts for $45 and blouses for $35. Its entire stock is worth $51,750. But sales are slow and only h

inysia [295]

Answer:

260 skirts and 270 blouses are left in the store after the sale.

Step-by-step explanation:

Let x be the number of skirts and y be the number of blouses.

An apparel shop sells skirts for $45 and blouses for $35

Cost of entire stock = $51,750

Thus, we can write the equation,

$45x + 35y = 51750$

Half the skirts and two-thirds of the blouses are sold for a total of $30,600.

Thus, we can write the equation,

$45(\dfrac{x}{2}) + 35(\dfrac{2y}{3}) = 30600\\\\135x + 140y = 183600$

Solving the two equations by elimination method, we have,

$135x + 140y-(135x + 105y) = 183600 - 155250\\35y = 28350\\\\y = \dfrac{28350}{35} =810\\\\x = \dfrac{51750-35(810)}{45} = 520$

Thus, there were 520 skirts and 810 blouses in the store.

Skirt left =

$520-\dfrac{520}{2} = 260$

Blouses left =

$810 - \dfrac{2}{3}\times 810 = 270$

Thus, 260 skirts and 270 blouses are left in the store after the sale.

Can someone check this, please (I do report as needed and I do mark brainliest)? Thank you!

Answer:

Step-by-step explanation:

cotx/cscx=cosx

Start on the left side.

cos(x) csc(x)

Apply the reciprocal identity to csc (x) .

cos(x) 1/sin(x)

Simplify

cos(x) 1/sin(x)cos(x)/sin(x)

Rewrite cos(x)/sin(x) as cot(x) .

cot(x)

Because the two sides have been shown to be equivalent, the equation is an identity.

cos(x) csc(x)=cot(x) is an identity

cot(x)−tan(x)/sin(x)cos(x)=csc^2(x)−sec^2(x) is an identity

You are correct :)

How does unemployment hurt an economy? Check all that apply.

stellarik [79]

The <u>correct answers</u> are:

Unemployed people usually buy fewer things.
Unemployed people may not be able to repay their loans.
Unemployed people may have to to change their financial goals.

Explanation:

If someone is unemployed, they have much less money with which to purchase items, so they usually purchase less. This hurts the businesses that would profit from these purchases.

If someone is unemployed, their ability to pay their bills is affected since their income is gone. This means they may not be able to repay any loans they have in their name. This hurts the banks that have loaned the money.

If someone is unemployed, they may have to adjust their financial priorities. If they were looking to invest money, they no longer have it to invest. If they were looking to purchase real estate, again, they no longer have the money to do that. This hurts banks that they may invest through and the people or agencies that they would be purchasing real estate through.
