B.2.83 cuz 100/6 is 16.6 and multiply it by 6 for each (as a fraction), you'll get 0.83 (rounded). The add the 2 as the wholes(before the decimal).<span />

Which of the following arguments correctly justifies the second step of the flow proof of the triangle angle sum theorem below
pochemuha
We need to see the second step of the proof, so we know what needs to be justified. It would also be nice to see the list of answer choices. I'll never understand how someone who can't answer the question and has to ask someone else can then go ahead and decide that the person helping him only needs to see parts of the question.

Philip and Kevin are hoping to earn enough money to buy concert tickets for a show that costs $225 her concert tickets. Philip a
liubo4ka [24]

Answer:

Kevin will earn the money before than Philip

Philip needs at least 4 weeks

Kevin needs at least 3 weeks

Step-by-step explanation:

Let's call x to the number of weeks

Philip works 6 hours each weekend, which means 6 hours per week, earning $8.75 per hour, which is equivalent to 6*8.75 = $52.5 per week

Philip has already saved $45. Then he needs the next number of weeks:

52.5*x + 45 = 225

x = (225 - 45)/52.5

x = 3.4

Philip needs at least 4 weeks

Kevin works 3 hours per day for 3 days a week, which means 9 hours per week, earning $7.5 per hour, which is equivalent to 9*7.5 = $67.5 per week

Kevin has already saved $30. Then he needs the next number of weeks:

67.5*x + 30 = 225

x = (225 - 30)/67.5

x = 2.9

Kevin needs at least 3 weeks

The focal length of the given ellipse is given as (±6, 0)

<h3>Equation of an ellipse</h3>

An ellipse is defined as a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant or when a cone is cut by an oblique plane which does not intersect the base.

The standard equation of an ellipse is expressed as;

x^2/a^2 + y^2/b^2 = 1

The formula for calculating the focus of the ellipse is given as:

c^2 = b^2 - a^2

Given the equation of an ellipse

(x-7)^2/64 + (y-5)^2/100 = 1

This can also be expressed as:

(x-7)^2/8^2 + (y-5)^2/10^2 = 1

Comparing with the general equation

a = 8 and b = 10

Substitute

c^2 = 10^2 - 8^2

c^2 = 100 - 64

c^2 = 36

c = 6

Hence the focal length of the given ellipse is given as (±6, 0)
