Answer:

2π feet

Step-by-step explanation:

9:30 PM to 1:30 AM is 4 hours.

It is 1/3 of a complete revolution.

A full 12 hours would be 2×r×π=2×3×π

1/3 of that is:

1/3×2×3×π=2π

≈6.283185307 feet

What is the ratio of the width of the yard to the area of the yard in 10 feet long by 7 feet wide
dezoksy [38]

Area = (length) x (width)

Area = (10-ft) x (7-ft) = 70 ft²

(Width) / (Area) = (7-ft) / (70 ft²)  =  1 / 10-ft .

Evaluate each expression if a = 4.1, b = 5.7, and c=0.3.<br> 4. a+b-c <br> 5. 10-(a+b)<br> 6. B- c+2
posledela

Answer:

  • a+b-c = 9.5
  • 10-(a+b) = 0.2
  • b-c+2 = 7.4

Step-by-step explanation:

4)

Given the expression

a+b-c

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

a+b-c = 4.1+5.7-0.3

          =  9.8 - 0.3

          = 9.5

5)

Given the expression

10-(a+b)

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

10-(a+b) = 10 - (4.1+5.7)

              = 10 - 9.8

              = 0.2

6)

Given the expression

b-c+2

  • a=4.1
  • b=5.7
  • c=0.3

substituting the values in the expression

b-c+2 = 5.7 - 0.3 +2

          = 5.4 + 2

           = 7.4

Determine which system of equation has (-3,19) and (4,-23) as a solution?
grandymaker [24]

Answer:

y=6x+1

Step-by-step explanation:

First you must find the slope of the two points...

\frac{4--3}{-23-19} which then would equal 6

Then you take the slope and put into point-slope form

(y-y1)=m(x-x1)...take one of the points that is given and plug it into this formula.

so I used (-3,19).

(y-19)=6(x--3)

I would then get y-19=6x+18

Add 19 to both sides and you will get y=6x+1
