Answer:

-4/11

Step-by-step explanation:

This cannot be a positive number because 1*-11=-11. This means all positive numbers will not work. It can't be more than less than -1 because -1*-11= 11. -4/11*-11=4

Answer:

b = -(4/11)

Step-by-step explanation:

-11b = 4

Division Property of Equality

b = -(4/11)

There’s not really any other way to explain it other than you divide both sides by -11.

A car rental agency advertised renting a car for $26.95 per day and $0.27 per mile. If David rents this car for 3 days, how many

Lapatulllka [165]

Step-by-step explanation:

1 day = $ 26.95

3 days = 26.95 × 3

= $80.85

Remainder = $100 - $80.85

= $19.15

1 mile = $ 0.27

= $19.15 ÷ $0.27

= 71 miles

Use the points H(−4, 1) and K(4, 1). Complete the description of segment HK and find its length.

aniked [119]

Use the points H(−4, 1) and K(4, 1).

(a) From two points , we will get a vertical line when 'x' values are same and horizontal line segment when 'y' values are same

Here in H(−4, 1) and K(4, 1) , the y values are same so the segment HK is a horizontal . The length is the difference between x values ( 4 -(-4)) = 8

Segment HK is a Horizontal segment that is 8 units long.

(b) Describe the image of segment HK under the transformation

(x, y) -----> (−y, x)

H(−4, 1) -----> (-1, -4)

and K(4, 1) ---> (-1, 4)

'x' values are same so line HK is Vertical. The length is the difference between y values ( 4 -(-4)) = 8

The image of segment HK is a Vertical segment that is 8 units long.

(x, y) ----> (2x, y)

H(−4, 1) -----> (-8, 1)

and K(4, 1) ---> (8, 1)

'y' values are same so line HK is Horizontal. The length is the difference between y values ( 8 -(-8)) = 16

The image of segment HK is a Horizontal segment that is 16 units long.

Please help!!!!! Math is very confusing and this makes no sense

The missing figure is attached down

The length around the outside of the track is about 431 feet

Step-by-step explanation:

A running track has the shape of a rectangle capped with a semicircle on each end

The track is 80 feet wide
The rectangular portion of the track is 90 feet tall

We need to estimate the length around the outside of the track

The length of the outside the track is the length of two semi-circle and two straight lengths of the rectangle

∵ The track is 80 feet wide

- From the figure the width of the track is the diameter of the

semi-circles

∴ The diameter of each semi-circle = 80 feet

∵ The radius of a circle is half its diameter

∴ The radius of each semi-circle = $\frac{1}{2}$ × 80 = 40 feet

∵ The length of a circle = 2πr

∴ The length of a semi-circle = πr

∴ The length of two semi-circle = 2 × πr

- Substitute r by 40

∴ The length of two semi-circle = 2 × π(40) = 80π feet

∵ The rectangular portion of the track is 90 feet tall

∴ The length of the rectangle = 90 feet

∴ The two straight parts of the track = 2 × 90 = 180 feet

- Add the length of the two semi-circles and the two straight

parts to find the length of the track

∵ Length of the track = 80π + 180

- Substitute π by 3.141

∴ Length of the track = 80(3.141) + 180

∴ Length of the track = 431.28 ≅ 431 feet

The length around the outside of the track is about 431 feet
