Answer:

C.  \frac{\sqrt{5} }{8}

Step-by-step explanation:

This expression can be rewritten as \frac{\sqrt{5} }{\sqrt{64} }.

Since the square root of 5 is prime and does not have any perfect square factors, it cannot be simplified. However, the square root of 64 is equal to 8, so our final simplified radical expression would be \frac{\sqrt{5} }{8}, which is option C.

HOPE THIS HELPED! :)

C is the answer

Step-by-step explanation:

You have to rewrite as \sqrt{5}/\sqrt{64}. Then you have to simplify the denominator which is 8. That is how you get your answer.

Hope this helps.

THIS IS REALLY IMPORTANT 7TH GRADE MATH:
Oksana_A [137]

Rectangle perimeter is 53 meters.

L = W + 2.3

To find the options of a perimeter, divide by 4.

= 13.25

So if this was a square, it would be 13.25 for both L and W but it's not.

Since the W has 2.3 meters more then the L, we do this.

13.25 + 2.3 = 15.55

13.25 - 2.3 = 10.95

Two of your sides equal 15.55, and the other two equal 10.95.

Hope this helps!

A store is having a sale on walnuts and chocolate chips. For 8 pounds of walnuts and 4 pounds of chocolate chips, the total cost
astra-53 [7]

Answer:

x = $3.50; y = $2.25

Step-by-step explanation:

First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.

3x + 2y = 15

3x = 15 - 2y

x = (15 - 2y)/3

Plug in the answer to your second equation.

8(15 - 2y)/3 + 4y = 37

(120 - 16y)/3 + 4y = 37

120 - 16y + 12y = 111

120 - 4y = 111

-4y = -9

y = 2.25

Plug in your answer to find <em>x.</em>

3x + 2(2.25) = 15

3x + 4.5 = 15

3x = 10.5

x = 3.5

Check your equation.

1) 3(3.5) + 2(2.25) = 15

10.5 + 4.5 = 15

15 = 15

2) 8(3.5) + 4(2.25) = 37

28 + 9 = 37

37 = 37
