I'll start 18 and 22 for you, and you should then be able to do the rest on your own!

For 18, what we literally do is apply the distance formula for all the points and add them up. For B to C, we get the distance between them to be
sqrt((x1-x2)^2+(y1-y2)^2)=sqrt((0-4)^2+(3-(-1))^2)=sqrt((-4)^2+4^2)=sqrt(16+16)=sqrt(32). Repeat the process for C to E, E and F, and F to B then add the results up to get your answer!

For 22, since the area of a rectangle is length*width (we know given the right angles and that the opposite sides are equal in how long they are), we can multiply 2 perpendicular lines, for example, BC and CE to get sqrt(32)*sqrt(8)=16 as the area

dedylja [7]

Answer:

89 rooms should be set for early book customer

Step-by-step explanation:

According to the given data we have the following:

OVERAGE(CO) = 200

SHORTAGE(CS) = 500

In order to calculate how many rooms should be set for early book customer we would have to use the following formula:

OPTIMAL BOOKING = MEAN + (Z * STDEV)

MEAN = 75

STDEV = 25

SERVICE LEVEL= CS / (CS + CO) = 500 / (500 + 200) = 0.7143

Z VALUE FOR 0.7143 = 0.57

OPTIMAL BOOKING =  75 + (0.57 * 25) = 89

89 rooms should be set for early book customer

Can you please help me with this

Answer:

-The total area of a Rectangular Prism:

A = 366 in^{2}

Step-by-step explanation:

-To find the total area of a rectangular prism, you need this formula:

A = 2(l \cdot w +  l \cdot h + w \cdot h)

l = Length

w = Width

h = Height

-Apply the length, width and height for the formula:

A = 2(11 \cdot 8 +  11 \cdot 5 + 8 \cdot 5)

l = 11 in

w = 8 in

h = 5 in

-Then, solve for the area:

A = 2(11 \cdot 8 +  11 \cdot 5 + 8 \cdot 5)

A = 2(88 + 55 + 40)

A = 2(143 + 40)

A = 2 \times 183

A = 366

So, the total area would be 366 in ^{2}.
