11-4=7. Orca correct.

Sea star...11-4=7

Answer:

The orca is right and the sea star is wrong.

If you were to add 11 to -4, it would no longer be a negative number.

You take four out of 11 which would bring it to a zero. There would be 7 left, therefore the answer being a positive 7.

Solve by substituting the equation y=-x-6 y=x-4<br>(plz show work)
Elena-2011 [213]

Answer:

x = -1, y= -5

Step-by-step explanation:

y=-x-6

y=x-4

Since both equations are equal to y we can set them equal to each other

-x-6 = x-4

Add x to each side

-x-6+x = x-4+x

-6 = 2x-4

Add 4 to each side

-6+4 = 2x-4+4

-2 =2x

Divide by 2

-2/2 = 2x/2

-1 = x

now find y

y = x-4

y = -1-4

y = -5

Randy is starting a beehive so that he can have fresh honey. He decides to check the current population of bees in the hive by m
satela [25.4K]

Answer:

Best estimate for the bee population is 1280.

Step-by-step explanation:

Randy marked total number of bees = 160

Then he collected 240 bees and observed that number of bees marked

= 30

We have to find the total population of the bee or best estimate for the bee population.

Now we use the ratio of marked bees in the sample vs marked bees in the total population

\frac{\text{Number of bees marked in the sample}}{\text{Total bees in the sample taken}}=\frac{\text{Number of bees marked in total population}}{\text{Number of bees in the hive}}\frac{30}{240}=\frac{160}{x}

x = \frac{160\times 240}{30}=1280

Therefore, the best estimate for the bee population is 1280.

To find the number of units that gives break-even for the product, solve the equation R C. Round your answer to the nearest whol
Harrizon [31]

Answer:

The correct answer is D.

Step-by-step explanation:

Giving the following information:

R = 90x

Total cost= 35x + 17,000

x= is the number of units produced and sold

Now, we know that:

Unitary variable cost= 35

Fixed costs= 17,000

Selling price per unit= 90

To calculate the break-even point in units, we need to use the following formula:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 17,000 / (90 - 35)

Break-even point in units= 309 units
