Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete. W

hat is the equation that can be used to find the value of y, the total time that Vlad spent on his homework, and what are the constraints on the values of x and y?
y=2x+20; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=2x+20; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20.
y=20x+2; x is any integer greater than or equal to 0, and y is an integer greater than or equal to 20.
y=20x +2; x is any real number greater than or equal to 0, and y is any real number greater than or equal to 20

Reflect the triangle across the y-axis, and then translate the image 5 units down.
Ksju [112]

Step-by-step answer:

It is a glide reflection.

The order of sliding and reflection is not important if the gliding is parallel to the line of reflection, which is the case here.

So the equivalent is translate five units down, and then reflect over the y-axis.

Note in general that rotations will not be equivalent to an odd number of reflections.  So looking for an equivalent, look for reflection.

Every day 10% of the liquid present in the morning in Kyle's open container will evaporate. At the end of three days, what perce
lozanna [386]

At the end of three days,  72.9% of the original amount of liquid remains in Kyle's container .

<u>Step-by-step explanation:</u>

Here we have , Every day 10% of the liquid present in the morning in Kyle's open container will evaporate. At the end of three days, We need to find what percent of the original amount of liquid remains in Kyle's container . Let's find out:

Let's suppose initially we have 100% of liquid present so ,

<u>At day 1:</u>

10% of the liquid present(100%) in the morning in Kyle's open container will evaporate , So left is :

⇒ 100- \frac{100(10)}{100}

⇒ 100-10

⇒ 90%

<u>At day 2:</u>

10% of the liquid present(90%) in the morning in Kyle's open container will evaporate , So left is :

⇒ 90- \frac{90(10)}{100}

⇒ 90-9

⇒ 81%

<u>At day 3:</u>

10% of the liquid present(81%) in the morning in Kyle's open container will evaporate , So left is :

⇒ 81- \frac{81(10)}{100}

⇒ 81-8.1

⇒ 72.9%

Therefore , At the end of three days,  72.9% of the original amount of liquid remains in Kyle's container .

Find P 20 of the following arithmetic sequence: 206, 212, 218, 224....
Yanka [14]

Answer:

p_{20} = 1.25528

P₀ = 206 and difference d = 6

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the arithmetic sequence

                 206,212,218,224,.....

P₀ = 206 and difference d = 212-206 = 6

The n^{th} term of the sequence

   t_{n} = ar^{n-1}

<u><em>Step(ii):-</em></u>

The n^{th} term of the sequence

   P_{n} = ar^{n-1}

Put n=20

P_{20} = 206 ( 6) ^{20-1}

p_{20} = 1.25528
