Answer:

area of circle=pi times radius^2

diameter/2=radius

area of rectangle=length times width

rectanlge-circle=scarf

rectanlge=28 by 15=28*15=420

circle, diameter is 15 so radius is 15/2=7.5

area=pi7.5^2=pi56.25=3.14*56.25=176.625

so

rectangle-circle=420-176.625=243.375 square inches

the area of the scarf is 243.375 square inches

Which equations may be used to determine the 3 consecutive integers whose sum is 127?
s344n2d4d5 [400]

Answer:

a and b.

Step-by-step explanation:

I’ll explain by giving an example.

Let’s say that: a=3;b=4;c=5; => they all are consecutive -> their sum is 12.

=> if we use a) n=3 => 3*n+3=3*3+3=12 => correct.

b) n+(n+1)+(n+2)= 3+4+5=12=> correct.

c)n+2n+3n=3+6+9=18=>incorrect.

d)3n=3*3=9=>incorrect.

There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me

i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)

THE ANSWER IS 68.9 CM

A university is composed of five schools. The enrollment in each school is given:
Lostsunrise [7]

Answer:

34.767 enrollments/computer

Step-by-step explanation:

According to the Hamilton's method, the standard divisor, D, is determined by dividing the number of enrollments in all schools by the number of new computers available:

D=\frac{1050+1410+1850+2540+3580}{300}\\D=34.767\  enrollments/computer

The standard divisor for this situation should be 34.767 enrollments/computer.
