She did everything correct in step 1 and 2

Until step 3 she took a wrong turn.

She wrote seven times x over seven = twenty-three over 7

**When she should have wrote..**

**negative seven times x over negative seven = twenty-three over negative seven**

So her answer was

23/7

while it should have been a negative. -> -23/7

Good Luck! :)

**Answer: **45 feet by 67.5 feet.

**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.**

**Answer:**

**Step-by-step explanation:**

THe sequence 64,16,4,1 as you can see it´s actually going down or decreasing, so the ratio should be a fraction, in order to find that you just have to pair two terms that are next to eachother in the sequence to find the fraction, let´s try it with the first two: 64 and 16:

So the ratio is 1/4. You can confirm the ratio by using other numbers in the sequence, like the last two:

This is the ratio directly.

To answer the question above, substitute the given value of height.

25 = -16x² + 50t + 4

Solving the following equation by the use of quadratic formula,

x = (-b +/- sqrt (b² - 4ac)) / 2a

Subsituting the known values of a, b, and c

x = (-50 +/- sqrt (50² - 4(-16)(-21)) / 2x-16

The values of x are 0.5 and 2.625. Therefore, the answer is the fourth choice.

Find the area (A) of the rectangular wall by multiplying the dimensions,

A = L x W

Substituting,

A = (32 ft) x (16 ft) = 512 ft²

a. (512 ft²) x (1 L / 100 ft²) x (1 gal/ 3.79 L) = 1.35 gal

b. The nearest whole number that is greater than 1.35 is 2. So, 2 containers should be bought.

c. There will remain an amount of 0.65 gallon which is equal to 2.4635 L.

A = L x W

Substituting,

A = (32 ft) x (16 ft) = 512 ft²

a. (512 ft²) x (1 L / 100 ft²) x (1 gal/ 3.79 L) = 1.35 gal

QUESTION POSTED AT 29/01/2020 - 04:30 PM

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.

The population density (d) of the fish in the tank is the number of fishes (n) in a given volume (v)

d = n / v

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

Thus, the volume of the tank is 50 ft³.

d = n / v

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
