What's the square root of 64 times 3
Answer:
24
Step-by-step explanation:
Answer:
About 13.86
Step-by-step explanation:
64 x 3 = 192
[tex]\sqrt{} 192[/tex] = 13.8564064606
If you were asking what [tex]\sqrt{64}[/tex] multiplied by 3 was, that answer would be 24. I read it as if you were asking what [tex]\sqrt{64 x 3}[/tex] is. :)

I WILL GIVE BRAINLIST TO THE BEST ANSWER!!!
ALSO I NEED YOU TO TELL ME HOW TO DO IT!!!
Answer:
4
Step-by-step explanation:
We are asked to find a slope whilst given a graph.
To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.
So based on what I see, I can see (1, 1) and (2, 5).
The rise over run is as followed :
[tex]\frac{y2 - y1}{x2 - x1}[/tex]
2 and 1 meaning the first and second number within the coordinate, so substitute :
[tex]\frac{5 - 1}{2 - 1}[/tex]
[tex]\frac{4}{1}[/tex]
Divide :
[tex]4[/tex]
4 is our slope.

A hoodie is on sale for $48. This sale price is 80% of the original price. What was the original price of the hoodie?
Answer: 60 dollars
===============================================
Work Shown:
x = original price
y = sale price
The sale price is always smaller than the original price, so y < x.
The equation linking the two variables is
y = 0.8x
since 80% = 80/100 = 0.8
We know the sale price is $48, which means y = 48. This leads to:
y = 0.8x
0.8x = y
0.8x = 48
x = 48/0.8
x = 60
The original price was $60
Note: since the sale price is 80% of the original price, this must mean that we have a 20% discount (100% - 80% = 20%)
