Answer:

Given: $r\perp s$ and $t\perp s$ .

Prove: $r\parallel t$

Since $r\perp s$ , By the definition of perpendicular lines angles 1, 2, 3 and 4 are 90 degree. similarly $t\perp s$ , it means angles 5, 6, 7 and 8 are 90 degree.

We can say that,

$\angle 1\cong \angle 5$ , $\angle 2\cong \angle 6$ , $\angle 3\cong \angle 7$ and $\angle 4\cong \angle 8$

From figure it is noticed that the angle 1 and 5 are corresponding angles.

If two parallel lines are intersected by a transversal, then the corresponding angles are equal.

Since corresponding angles are congruent, therefore the line must be parallel to each other.

Hence proved that $r\parallel t$ .

Vavilen inflated a huge balloon in 19 minutes. Then he poked a hole in the balloon so that it slowly leaked air out until it was

kaheart [24]

Considering balloon to be an spherical object

Volume of sphere = $\frac{4}{3}\pi r^3$ , where r is the radius of sphere.

After 19 minutes ,If radius of balloon changes from r to R, the Volume changes from V to V'.

V'= $\frac{4}{3}\pi R^3$ ,

As given,rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon.

Also, $\frac{dR}{dt}=2 \times \frac{dr}{dt}$

Now, again the radius changes from R to r.So, Volume changes from V' to Back to V.

Time taken by the balloon to deflate = 38 minutes

But there is no relation between time and volume of Balloon.

So, we can't predict at which rate balloon is deflating or inflating.Apart from the statement given in Question: $\frac{dR}{dt}=2 \times \frac{dr}{dt}$

Given m ll n, find the value of x and y. Can someone answer this today please

Artemon [7]

Answer:

x = 15, y = 50

Step-by-step explanation:

m and n are parallel and cut by a transversal

Finding x

8x + 12 + 2x + 18 = 180 (consecutive interior angles sum up to 180°)
10x + 30 = 180
10x = 150
x = 15

Finding y

8x + 12 = 3y - 18 (vertical angles are equal)
8(15) + 12 = 3y - 18
132 = 3y - 18
150 = 3y
y = 50

A group of 72 people travel to the beach for a clean-up day. Some of the people bring their own supplies (such as gloves, water,

Doss [256]

Answer:

72-b=p

Step-by-step explanation:

You start with 72, then take away the people bringing their own supplies (b), and that equals the number of people that will have supplies provided for them (p).

72-b=p

Six times a number is decreased by 20 which is equal to three times the number increased by 4. what is the number?

loris [4]

Let the number be a
6a - 20 = 3a + 4
Group like terms
6a - 3a = 20 + 4
3a = 24
divide through by 3
a = 8
Therefore the number is 8
