The given radical is

$7 \sqrt{7} - 2 \sqrt{28}$

Remove the perfect square from the second radical.

$= 7 \sqrt{7} - 2 \sqrt{4} \times \sqrt{7}$

$= 7 \sqrt{7} - 2 \times 2 \times \sqrt{7}$

Answer: 105

Step-by-step explanation: 25 frames is 1 second. The video already played 3 and 2/5 seconds before the player started to count 0, so you can write 3 and 2/5 seconds as an improper fraction. =(5*3)+2 / 5 = 17/5 seconds. Multiply by 25 frame. 17/5 *25 =85 frames. So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames. then to get the number of frames that were already in count you would subtract 85 frames from the 190 frames.

190-85=105 frames

(Not 100% sure so apologies if I'm wrong)

Which of the following is a rational number?

Morgarella [4.7K]

Answer:

Square root of 100.

Step-by-step explanation:

Step-by-step explanation:

We can write 10 as a fraction 10/1, therefore, $\sqrt{}$ 100 is a rational number.

Part A : A rational no. between 5.2 and 5.5 is 5.3.

It is rational because it can be expressed in the form

p/q where p and q are integers and q is not equal to 0, which is 53/10

Part B: A rational no. between 5.2 and 5.5 is 5.29150262213

An irrational number between 5.2 and 5.5 is 5.29150262213. It is irrational because there is no pattern that repeats and it cant be written as a fraction of two whole numbers.
