Step-by-step explanation: Given: To draw the sketch of the Roosevelt room in the white house= The dimensions of the sketch is 3 feet by 4.5 feet . To find the actual dimensions of the room multiply the dimensions of the sketch by the reciprocal of scale factor . [because to sketch we need to multiply scale factor to the actual dimensions] The reciprocal of the scale factor = 3 feet → feet 4.5 feet → feet Hence, The dimensions of the actual dimensions of the room is 45 feet by 67.5 feet.

I give a medal to anyone to tries!!! 3 party-goers are in the corner of the ballroom having an intense argument. You walk over to settle the debate. They are discussing a function g(x). You take out your notepad and jot down their statements. • Professor McCoy: She says that 2 is a zero of g(x) because long division with (x + 2) results in a remainder of 0. • Ms. Guerra: She says that 2 is a zero of g(x) because g(2) = 0. • Mr. Romano: He says that 2 is a zero of g(x) because synthetic division with 2 results in a remainder of 0. Well, the way I see it is that both Mr. Romano, and Ms. Guerra are correct but Professor McCoy is incorrect because he said (x+2) when it should be (x-2). The factor theorem states that: If f(a)=0, then (x-a) is a factor The remainder theorem states that: If (x-a) is a factor of f(x), then f(x) / (x-a) = 0 So if 2 is indeed a zero of f(x), then a factor must be (x-2) according to the fist which supports Ms. Guerra and also if (x-2) is indeed a factor as Ms. Guerra says then we know that f(x) / (x-a) = 0 which supports Mr. Romano Professor McCoy is wrong because he used (x + 2) when it should be (x-2). I know this because according to the factor theorem if f(a)=0, then (x-a) is a factor. And the remainder theorem says if (x-a) is a factor of f(x), then f(x)/x-a =0.

How many cabinets must he sell to break even?

The break-even point is the point where the total sales or revenue is equal to the total costs of the process. In this case, the total sales is represented by    y = 1400+400x while the total costs is represented by the equation y = 600x. We equate the two equations 1400 + 400x = 600 x to get the number of cabinets to be sold. x is equal to 7 cabinets. The answer is 7 cabinets.

Step-by-step explanation:

Let line segment AB represents the length of the lamppost (In which A shows the top), CD shows the height of the man ( C shows his head ) and E represents the tip of the shadow.

Hence, According to the question,

AD = 15 feet, DE = 5 feet and ∠ E = 50

By the below diagram,

Thus, the approximately length of the lamppost = 24 feet.

The volume is the quotient when n is divided by d. Substituting the known values,
v = n / d  = 15 fish / 0.3 fish over ft³
