Answer:

Q and R

Step-by-step explanation:

So lets look at the triangle.

P seems very thin, wheareas Q and R seem wider.

Normally, if given the degrees of the angles, we can subtract them from 180, which is the degrees of a full triangle, to find if two or more angles are congruent.

In this case however, we just go off of looks.

We see that angle P points strait up. This would not be the case if either Q or R where not going at the same angle, for if they were not congruent, angle P would be tilted to either the left or rihgt side.

So in the end, the best answer is Q and R.

HOpe this helps!

Gordon Ramsey made a stew that contained shrimp and potatoes. Shrimp was expensive, so he used three times the amount of potatoe

Burka [1]

Answer:

He bough 1.25 lbs of shrimp and 3.75 lbs of potato.

Step-by-step explanation:

Since the stew is composed of shrimps and potatoes, then the sum of the weighs of these ingredients must be equal to the weigh of the stew, so we have:

$shrimp + potato = 5$

We also know that he bought three times more potatoes than shrimps, therefore:

$potato = 3*shrimp$

Using the second equation on the first one, we have:

$shrimp + 3*shrimp = 5\\4*shrimp = 5\\shrimp = \frac{5}{4} = 1.25$

$potato = 3*shrimp = 3*1.25 = 3.75$

He bough 1.25 lbs of shrimp and 3.75 lbs of potato.

Hospital sells raffle tickets to raise fund for new medical equipment. Last year, 2000 tickets were sold for $24 each. The fund-

Zanzabum

Answer:

1) Price decrease = $4; 2) new price = $20; 3) maximum revenue = $50 000

Step-by-step explanation:

The hospital sold 2000 tickets for $24 each

Revenue = price per ticket × number of tickets sold

Let x = change in price

New price = 24 - x

New number of tickets sold = 2000 + 125x

1) Calculate change in price to maximize revenue

y = (24 - x)(2000 + 125x)

y = 48 000 + 1000x - 125x²

y = -125x² + 1000x + 48 000

a = -125; b = 1000; c = 48 000

The vertex is at

$x = -\dfrac{b}{2a} = -\dfrac{1000}{2(-125)}= \dfrac{1000}{250} = \mathbf{4}$

A price decrease of $4 will maximize revenue.

2) New ticket price

Original price = $24

Price change = <u> - 4 </u>

New price = $20

A ticket price of $20 will maximize revenue.

3) Maximum revenue

Ticket price = $20

No of tickets sold = 2000 + 125(4) = 2000 + 500 = 2500

Revenue = 2500 × $20 = $ 50 000

The maximum revenue is $50 000.

The graph below slows the relation between the price drop and total revenue. A price drop of $4 results in a maximum revenue of $50 000.

Identify the equation of the translated graph in general form x^2+y^2=7 for T(-8,4) A. x^2 + y^2 + 16x - 8y + 73 = 0 B. x^2 + y^

Lunna [17]

Answer:

The correct option is A

Step-by-step explanation:

The standard form of equation of circle is written as:

(x - a)² + (y - b)² = r²

Where centers is given as (a,b)

The equation of the circle given in the question is:

x² + y² = 7

If the circle is translated T(-8,4), it means that the centre of translated circle lies at (-8,4).

So standard form of equation of circle is:

(x + 8)² + (y - 4)² = 7

Simplifying the equation:

(x² + 64 + 2(x)(8)) + (y² + 16 - 2(y)(4)) = 7

x² + 64 + 16x + y² + 16 - 8y = 7

x² + y² + 16x - 8y + 80 = 7

x² + y² + 16x - 8y + 80 - 7 = 0

x² + y² + 16x - 8y + 73 = 0

which is the general form of the equation of circle
