Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you want to find out what the slope is, you have to remember what the formula is first....

$m=\frac{y}{x} =\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

so in this case -3 would be the $y_{2}$ because it's the y in the ordered pair and it's the second one. Then one of the 5's would be $x_{2}$ and 9 would be $y_{1}$ and then the other 5 would be $x_{1}$ .

now if we plug it in

$\frac{-3-9}{5-5} =\frac{-12}{0}$

now we can tell that we can't divide by zero so the slope would be unidentified and that's it.

Shawn drew a rectangle that was 2 units wide and 6 units long. Draw a different rectangle that has the same perimeter area.

Nitella [24]

Answer:

A square that has sides of 4.5 units, or a rectangle that is 1 unit wide and 8 units long.

Step-by-step explanation:

First, you need to find the perimeter in the first place. Since there are two sides of the same number, you would double each number.

2 would become 4

6 would become 12

Add 4+12=18

So, our rectangle has to have a perimeter of 18 units. Because a square is a rectangle, you can divide 18 and 4, since a square has 4 sides. You get 4.5. Each side can be 4.5 units.

Or, you can have a rectangle. What I thought first was a length of 9, but I knew that wouldn't work. I drew a rectangle and tried 8. If I put it on the top and bottom, which you need to to find the perimeter, it was only 16. Then I knew I could use 1 as a side length. If you added the sides, it would equal 2, and when you add 16 and 2, it's 18. So, you can use a rectangle that has a length of 8 units and a width of 1 unit.

The area swept by the minute hand in 12 minutes is 181.58 cm²

Step-by-step explanation:

In the circle clock

The circumference of the circle is divided into 12 equal arcs
The central angle of each arc is 30°, because the measure of the circle is 360° and divided by 12
The central angle between each two consecutive hours is 30°
There are 5 minutes between each two consecutive hours, then the central angle between each two consecutive minutes is 6° because 30° ÷ 5 = 6°
When the minute hand is moved than the radius of the circle is the length of the minute hand
When the hour hand is moved than the radius of the circle is the length of the hour hand

∵ The minute hand is swept by 12 minutes

∵ The central angle between each two consecutive minutes = 6°

∴ The central angle when the minute hand swept 12 minutes =

6 × 12 = 72°

∵ The area of a sector of a circle = $\frac{x}{360}*\pi r^{2}$ ,

where r is the radius of the circle and x is the central angle of

the sector

∵ The radius of the circle is the length of the minute hand

∵ The minute hand in a clock is 17 cm long

∴ r = 17 cm

∵ The measure of the central angle is 72°

∴ x = 72°

- Substitute these values in the rule of the area of a sector

∵ Area = $\frac{72}{360}*\pi (17)^{2}$

∴ Area = 181.58 cm²

The area swept by the minute hand in 12 minutes is 181.58 cm²

36 men can compete a piece of work in 18 days in how many days will 27 men compete the same work

Drupady [299]

Step-by-step explanation:

Explanation:

Less Men, means more Days {Indirect Proportion}

Let the number of days be x then,

27 : 36 :: 18 : x

[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]

=>27x = 36 * 18

=> x = 24

So 24 days will be required to get work done by 27 men..

If the measure of an angle is 38 degrees, find the measure of its complement.

Norma-Jean [14]

Answer: 52 degrees

Explanation:
For this problem, we must know that the complement of an angle is the measure of which will make a 90 degree sum.

So in this problem we simply solve the equation as follows:

38 + x = 90
x = 90 - 38
x = 52

Hence the complement of 38 is 52.

Cheers.
