Answer:

$\sqrt{p^2+q^2}$

Step-by-step explanation:

The distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ can be calculated as

$\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}.$

Then the distance between points $(p,q)$ and $(0,0)$ is

$\sqrt{(p-0)^2+(q-0)^2}=\sqrt{p^2+q^2}.$

In 15 minutes Frankita created 15 drawings. In 30 minutes she created 17 drawings. In 45 minutes she created 20 drawings. In 60

SVETLANKA909090 [29]

Answer:

Frankita will create <u>29</u> drawings at the end of 75 minutes.

Step-by-step explanation:

Now below shown is the pattern used by Frankita:

15 min = 15 drawing

30 min = 17 drawing ⇒ increase by 2 (15+2 = 17)

45 min = 20 drawing ⇒ increase by 3 (17+3 = 20)

60 min = 24 drawing ⇒ increase by 4 (20+4 = 24)

75 min = 29 drawing ⇒ increase by 5 (24+5 = 29)

Hence We can say that Frankita will create <u>29</u> drawings at the end of 75 minutes.

Gabriella plays video games from 2:49 P.M. To 3:32 P.M. Mason plays video games for 35 minutes. How many minutes longer does Gab

Mekhanik [1.2K]

Answer:

Mizuki here to help!

8 minutes longer will be the correct answer!

Step-by-step explanation:

First, let's find out how many minutes Gabriella played:

3:32 - 2:49 = 2:92 - 2:49 = 0:43

Check:

2:49 + 0:43 = 2:92 = 3:32

It's correct so...

43 - 35 = 8

Hope this helped!

Which eqation is equivalent to 3x + 4y = 15

liubo4ka [24]

Answer:

$y=\frac{15-3x}{4}$

Step-by-step explanation:

Here we are given an equation in x and y and we are required to solve it for y

we have

$3x+4y=15$

subtracting 3x from each sides we get

$3x-3x+4y=15-3x$

$4y=15-3x$

now we divide both sides by 4 we get

$\frac{4y{4}=\frac{15-3x}{4}$

$y=\frac{15-3x}{4}$

Hence A) is our right answer.

What is 14/15 over 4/7 equal to

Aneli [31]

Answer:

$\frac{0.93}{0.57}$

Step-by-step explanation:

Simplify both of the fractions so $\frac{14}{15}$ to get 0.93 and $\frac{4}{7}$ to get 0.57.

Then you put them back into fraction form.

How many five letter strings are there that start with a consonant and end with Y where repetition is not permitted

Arada [10]

Answer: 242,880

Step-by-step explanation:

We know that:

We have 5 letters.

There is no repetition allowed.

The strings start with a consonant.

The strings end with the letter Y.

Ok, in our alphabet we have:

26 letters.

21 consonants

5 vowels.

Now, let's count the number of options for each one of the letters in the string.

First letter, this must be a consonant, initially, we can have 21 options, but this string must finish with an Y, and Y is a consonant, so it can not be in the first letter, then for the first letter we have 20 possible options.

Now we have a total of 26 - 1 - 1 = 24 letters left, where we subtracted the consonant for the first letter, and the Y for the last letter.

The options for the second letter will be 24.

The options for the third letter will be 23

The options for the fourth letter will be 22

For the last one we have a fixed value, so we have only one option.

The total number of combinations will be equal to the product between the numbers of options for each letter, this is:

C = 20*24*23*22 = 242,880 possible strings.
