QUESTION POSTED AT 22/02/2020 - 04:16 PM

It will be both of the girls burn the same amount of calories because 450/2 will give you 225 then you divide 620/2 you'll get 310. If you add 225+310, it will give you 535. That is for Carly. Then if you do 560/2, it will give you 280 then you divide 510 by 2, you'll get 235. 280+235= 535. That is for Sarah. As you can see, they are both the same results. I hope this is right!

### One train traveled south at 60 mph. The other traveled east at 50 mph. How far apart were the trains after 3 hours?

Let's called the train that traveled south train A, and the train that traveled east train B

After 3 hours, train A is 180 miles South
and Train B is 150 miles East

Using Pythagoras, distance between is sqrt(180^2 + 150^2)

12 is one.

4 x 3 = 12  3 x 3 = 9        6 x 2 = 12   1 x 2 = 2     2/12 & 9/12 = 11/12

2 + 0 = 2.  2 + 11/12 = 2 11/12.

The price of a ticket is$5000 per person. The agency has chartered a plane seating 150 people at a cost of $250 000. Additional costs to the agency are incidental fees of$300 per person. For each $30 that the price is lowered, one new person will sign up. How much should the price per person be lowered to maximize the profit for the agency? So hmm let's take a peek at the cost first so, they chartered the plane for 150 folks with a fixed cost of 250,000 now, incidental fees are 300 per person, if we use the quantity "x", for how many folks, then if "x" persons are booked, then incidental fees are 300x so, more than likely an insurance agency is charging them 300x for coverage anyway, thus the cost C(x) = 250,000 + 300x now, the Revenue R(x), is simple is jut price * quantity well, the price, thus far we know is 5000 for 80 folks, but it can be lowered by 30 to get one more person, thus increasing profits so... let's see what the price say y(x) is so.. now we know y(x) = -30x+7400 now, Revenue is just price * quantity the price y(x) is -30x+7400, the quantity is "x" that simply means R(x) = -30x²+7400x now, for the profit P(x) the profit is simple, that is just incoming revenue minus costs, whatever is left, is profit so P(x) = R(x) - C(x) P(x) = (7400x - 30x²) - (250,000+300x) P(x) = -30x² + 7100x - 250,000 now, where does it get maximized? namely, where's the maximum for P(x)? well and as you can see, if you zero out the derivative, there's only 1 critical point, run a first-derivative test on it, to see if its a maximum ANSWERED AT 28/03/2020 - 12:02 PM QUESTION POSTED AT 28/03/2020 - 12:02 PM ### Juan charges$3.50 per hour for baby-sitting.

### Tim’s quizzes count for 50% of his grade, his notes counts for 20% of his grade, and tests count for 30% of his grade. If he has quiz scores of 5, 2, and 9, notes scores of 3, 9, and 5, and test scores of 9, 5, and 9, his overall score is _____. Do not round your answer.

To find Tim's overall score, first we must find the sum of his scores from quizzes, notes, and tests.

Hence, we have

quizzes = (5 + 2 + 9) = 16/3
notes = (3 + 9 + 5)/3 = 17/3
tests = (9 + 5 + 9)/3 = 23/3

Now, we must consider the percentage that these tests contribute to his overall score. So we have the following:

quizzes = 0.5(16)/3 = 8/3
notes = 0.2(17)/3 = 3.4/3
tests = 0.3(23)/3 = 6.9/3

We now add these to find the overall score which is 8 /3+ 3.4/3 + 6.9/3 = 18.3/3 = 6.1.

Thus, Tim's overall score is 6.1.

### Circle A has a radius of 6 cm and arcs RC, CS, and SM are congruent. What is the length of arc RC? 30 60 120 180

Given that the 3 arcs are congruent, it means they have the same angle.
A circle measures 360 degrees, thus, let us divide it into three parts to get the arc length of the 3 arcs RC, CS, and SM which is in Circle A.
360 degrees / 3 = 120 degrees
Again, the three arcs are congruent so the length of arc RC is 120 degrees,  same with arcs CS and SM.

The amount of the bill is$178.95. If you pay the bill within 15 days, how much should you tender? A little help please?

you should tender $173.58 Step-by-step explanation: Your bill from Acme Supply Company is marked "3/15, net 30"' We know When "3/15, net 30" is marked on any bill, it means that if the bill is paid within 15 days there is 3% discount, otherwise net pay within 30 days. In this question it is asked that if you pay the bill within 15 days, so it is clear that you get the discount of 3% on the bill of$178.95.
Therefore we find the value less than 3% of $178.95. = 3/100 × 178.95 = 0.03 × 178.95 = 5.3685 rounded to$5.37.
= 178.95 - 5.37 = $173.58 If you pay the bill within 15 days, you should tender$173.58
