Answer:

12 sales

Step-by-step explanation:

Let x represent the number of sales each man had.

For Salesman A, he earns $65 per sale; this is 65x.

For Salesman B, he earns $40 per sale; this is 40x.  We also add to this his weekly salary of $300; this gives us 40x+300.

Since their pay was equal, set the two expressions equal:

65x = 40x+300

Subtract 40x from each side:

65x-40x = 40x+300-40x

25x = 300

Divide both sides by 25:

25x/25 = 300/25

x = 12

Determine the final amount after 20 years with a 5% annual interest rate if:you invest $10 000 in an account that earns compound
alekssr [168]

Answer:

$27,014.85

Step-by-step explanation:

We're gonna use the compound interest formula: P = A(1 + r/n)^nt

P = final amount

A = starting amount (10,000)

r = rate (0.05)

n = times applied (4 since it's quarterly)

t = years (20)

P = 10,000(1 + 0.05/4)^4*20

P = 10,000(1.0125)^80

P = 27,014.84940753337

Round it to just 27,014.85

at 3 weeks old, a corn is 4 inches tall and at 15 weeks it is 44 inches tall. calculate the rate of change.
pochemuha

Answer:

Im not a hundred percent sure if this is the right answer but im pretty sure it is 3.33333 repeated so the rate of change is 3 inches per week.

Step-by-step explanation:

I calculated the problem by subtracting the weeks from each other subtracting the amount of length corn has grown too. I found that the corn grew 40 inches in 12 weeks. So I divided the amount of weeks and the amount it has grown and it gave me 3.333333 repeated which makes the answer 3 inches per week. correct me if im wrong...

Hope this helps:)

An angle, θ, is in standard position. The terminal side of the angle passes through the point (-5, -3). Find tanθ.
spayn [35]
If the terminal ray of an angle passes through (-5, -3), that means it passes through x coordinate -5 and y coordinate -3.  Both x and y are negative in only one quadrant and that is the third one.  If we plot the point (-5, -3) in the coordinate plane in Q3, and then draw a vertical line to connect that point to the negative x axis and then draw a line to connect that point to the origin, what we have created is right triangle with a base of -5 and a height of -3. The tangent ratio relates the side opposite the reference angle to the side adjacent to the reference angle.  We have both of those measures already and do not have a need for the length of the hypotenuse since the tangent ratio doesn't use it.  The tangent of the reference angle is -3/-5 which is 3/5.
