Answer:

4.56

Step-by-step explanation:

i see a sector hosting 2 semi circles.

this sector area will be .25 of area of circle with radius 4ft.

area of sector = .25*π*16= 4π ft^2

area of semi circle of radius 2ft = .5π*4= 2πft^2

area of 2 semicircles = 4π

the total area of sector = area of 2 semicircles - intersection area + area not covered by semi circles

4π = 4π - intersection area+area not covered by semi circles

intersection area = area not covered by semi circles

now draw a square starting from the intersection point of 2 semi circles at their upper portion. the side will be 2ft

the area of intersection will be covered in the square.

area of intersection = 2*quarter area of circle of radius 2ft - area of square

= 2*(.25π4) - 4

2π-4 = 2.28

area of intersection = area not covered by semicircle

so area of shaded region = 4.56

Demichael orders a set of numbers on his
Andru [333]

The numbers are ordered, such that the first number (the largest one) is:

(5 + 1/2)

And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.

We want to see which of the following numbers is not on the list:

A) √25

B) 5.45

C) 5 12  

D) 5.34

One of these numbers can only be in the list if it is larger than  (5 + 1/3) and smaller than (5 + 1/2).

To see this easier, let´s rewrite both of these:

5 + 1/2 = 5 + 0.5 = 5.5

5 + 1/3 = 5 + 0.33 = 5.33

Then if a number is smaller than 5.33, the number can't be in the list.

Here we can see two numbers that are smaller than 5.33

These are:

Option A) √25 = 5 < 5.33

Option C) 5.12 < 5.33

And there is no number larger than 5.5

Concluding, the numbers that are not in Demichael's list are:

√25 and 5.12

PLEASE HELP!! There are 64 passengers on a morning bus. Of these passengers, 35 need transfers and 39 are going to work. There a
mote1985 [20]

The number of passengers that :

  • Needs Transfer only = 13 passengers
  • Are going to work only = 17 passengers

Let :

Passengers that needs transfer = T = 35

Passengers going to work, W = 39

Passengers who do not need transfers and aren't going to work = 12

Using a venn diagram :

Let the Passengers who do not need transfers and are going to work and needs transfer = x

Passengers who need transfer only = 35 - x

Passengers who are going to work only = 39 - x

To find x :

35 - x + 39 - x + x + 12 = 64

86 - x = 64

-x = 64 - 86

-x = - 22

x = 22

the number of passengers that need transfers but aren’t going to work will be = 35 - 22 = 13 passengers

the number of passengers that are going to work but do not need transfers will be : 39 - 22 = 17 passengers

URGENT!!!
Makovka662 [10]

Answer:

Train A - 50 miles per hour

train B - 30 miles per hour

Step-by-step explanation:

Let x mph be the speed of the train B, then the speed of the train A is (x+20) mph.

In 3 hours,

  • train A travels 3(x+20) miles
  • train B travels 3x miles

In total, they covered the distance of 240 miles, so

3(x+20)+3x=240\ \ \ \text{[Divide by 3]}\\ \\x+20+x=80\\ \\2x=80-20\\ \\2x=60\\ \\x=30\ mph\\ \\x+20=30+20=50\ mph

What is an interval scale and what is it used for?
koban [17]
An interval scale has measurements where the difference between values is meaningful. For example, the year 0 doesn’t imply that time didn’t exist. And similarly, a temperature of zero doesn’t mean that temperature doesn’t exist at that point. Arbitrary zeros (and the inability to calculate ratios because of it) are one reason why the ratio scale — which does have meaningful zeros — is sometimes preferred.
