The radicand is the number under the square root symbol. If it's a 2, then the 2 is rational, but its square root is irrational.

What is the value of y?

NeX [460]

The value of y in the triangle is 2√5

The triangle above is a right angle triangle.

Characteristics of a right angle triangle:

One of its angle is equals to 90 degrees
The sides can be found using Pythagoras theorem.

Using Pythagoras theorem

c² = a² + b²

where

c = hypotenuse(longest side)

a and b are the 2 other legs.

Therefore,

6² = 4² + y²

36 = 16 + y²

y² = 36 - 16

y² = 20

y = √20

y = 2√5

1250 lbs of sand.

So first let's find the volume of the sand in the sandbox. You have a square sandbox, with a side length of 5, meaning you have a length and width of 5. You also have half a foot of sand in the sandbox, meaning that you have a height of 0.5. To find the volume of the sand, multiply the length by the width by the height:

$5 * 5 * .5 = 12.5$

So you have 12.5 cubic feet of sand. If each cubic foot of sand is 100 lbs, then you just multiply the two:

$12.5 * 100 = 1250.0

Lines a and b are parallel. What is the measure of angle s? Enter your answer in the box. s = ∘∘ Horizontal parallel lines a and

VashaNatasha [74]

<span>s = 22 degrees

Assuming I'm interpreting your description accurately, the top right angle of line b will also be 158 degrees because it's a corresponding angle to the top right angle of line a. That means that the top left angle of line b will be a supplementary angle. And supplementary angles add up to 180. So 180 - 158 = 22.</span>

Express this in standard form 5.4×10^1

Naily [24]

Well it would just be 54 since you just need to move the decimal over by 1.

So 5.4x10= 54
