Hi there!

»»————-　★　————-««

I believe your answer is:

The square root of 5 ( $\sqrt{5}$ ) is irrational.

»»————-　★　————-««

Here’s why:

A rational number is a number that can be rewritten as a fraction of two integers with a nonzero denominator.

Rational numbers include integers, fractions, terminating decimal, or repeating decimals.
A square root that is perfect would be rational. A non-perfect square root is irrational.

⸻⸻⸻⸻

Since the square root of 5 is not a perfect square, it would be irrational.

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Find the sum of all the numbers between 100 and 200 which are divisible by 7.

frozen [14]

Answer:

2107

Step-by-step explanation:

In this type of question we have to follow these steps

1) Find the biggest number in interval which is divisible by seven

For this question it is 196

2)Find the smallest number in interval which is divisible by seven

For this question it is 105

3) Then subtract 105 from 196

196-105=91

4) Divide 91 by seven

91:7=13

5)Lastly we have to add 1 to the 13

13+1=14

So we found that we have 14 different numbers that divisible by seven in this interval. So next steps will be about sum of them

To find them sum we have a formula:

(biggest number + smaller number) x number of terms / 2

(196+105) x 14 /2 = 2107

A student spends $55.50 on school supplies at a store where the sales tax is 8%. What is the total cost of the supplies?

Inessa [10]

You would add 4.40 to 55.50 to get 59.90. because the sales tax is 8% which is 0.08 cents and multiply that by 55 to get 4.40
