Edurado started a business selling sporting goods.He spent $ 7500 to obtain hos merchandise , and it cost him $300 per week for

Alik [6]

Answer:

C) It will take 14 weeks for Edurado to make a profit.

Step-by-step explanation:

The money spent on obtaining the merchandise = $ 7500

The general expense per week = $300

Let us assume Eduardo has to work for N weeks to break Even.

So, the general expense in N weeks = N x( Expense per week)

= N x ( $300) = 300 N

So, the total expense in N weeks = Money spent on merchandise + general expense

or, the TOTAL EXPENSE = $ 7500 + 300 N .... (1)

Now, the earning per week = $850

So, the total earning in N weeks = N x ( Earning in 1 week) = N x ( $850)

or, the TOTAL EARNING = 850 N .... (2)

Now, for N weeks ,

TOTAL EXPENSE = TOTAL EARNING

⇒ $7500 + 300 N = 850 N

or, 7500 = 850 N - 300 N = 550 N

⇒ N = 7500/550 = 13.63

So, number of weeks should at least be 13.63

Among the given options, N = 14 weeks is the most feasible answer.

Hence, it will take 14 weeks for Edurado to make a profit.

2. In the ratio of 3:2:2, three brothers invested a total of 249,000 to open a store. Find each

GaryK [48]

Answer:

$106,714.29

$71,142.86

Step-by-step explanation:

There's a total of 7 pieces that they invested (3 + 2 + 2 = 7) so you can do 249,000 / 7 to find what each piece was worth.

249000/7 = about 35571.43

(you always have to round money to 2 decimal places)

Then the amount each brother spent would be:

3 * 35571.43 = 106714.29

2 * 35571.43 = 71142.86

For the triangle shown below, complete the following table.

dem82 [27]

Answer:

Step-by-step explanation:

In the given triangle

With reference angle A

perpendicular (P) = 3

hypotenuse (h) = 5

So sin A = p/h = 3/5

and

With reference angle C

perpendicular (p)= 4

hypotenuse (h) = 5

Sin C = p/h = 4/5

hope it helps :)

Which of the following expressions are equivalent to 2/x^6-y^6? Choose all that apply.

enot [183]

Answer:

A and C

Step-by-step explanation:

Equivalent expressions are expression which when simplified to lowest terms are equal.

Simplify each answer choice to find the expression which simplifies to $\frac{2}{x^6-y^6}$ .

A. Multiply the exponents 3*2 = 6. This is equal.

B. Multiply numerators and denominators. Here the numerator will be 1*1 = 1. It does not equal 2 in the numerator.

C. Here the numerator does equal 2. The denominator multiplies to $(x^3 - y^3)(x^3+y^3)\\x^6 -x^3y^3 + x^3y^3 -y^6\\x^6 - y^6$

This is equal.

D. The denominator will have three terms here when simplified. This will not be equal.
