Need help with number 40 plz. I was a little confused when I tried.
Olegator [25]

You can rewrite the decimal as a fraction  and compare the two fractions.  The fractions need to have a common denominator.

You can change the fraction to a decimal and compare.  take the numerator and divide it by the denominator.  


Unless I recognize the decimal as a fraction right away, I find it much easier to write the fraction as a decimal and compare

What is the value of 1/3 x^2 + 5.2y when x = 3 and y = 2?<br><br> PLZ HELP!!!
olasank [31]
The first step in solving this is to substitute x with 3 and y with 2, so that
\frac{1}{3} x^{2} +5.2y
becomes
\frac{1}{3}  (3)^{2} +5.2(2)
Then simply solve using the order of operations.
First exponents (there are no parentheses)
\frac{1}{3} 9 +5.2(2)
Then multiply and divide
3+10.4
And finally add and subtract
13.4
Therefore the value <span>of 1/3 x^2 + 5.2y when x=3 and y=2 is 13.4</span>

A 41 41-foot ladder is leaning against a building. The base of the ladder is 9 9 feet from the side of the building. How high do
lyudmila [28]

Answer:

The ladder would reach 40ft

Step-by-step explanation:

The ladder forms a right angle triangle with the building and the ground. The length of the ladder represents the hypotenuse of the right angle triangle. The height that the ladder would reach along the side of the building represents the opposite side of the right angle triangle.

The distance from the bottom of the ladder to the base of the building represents the adjacent side of the right angle triangle.

To determine the height that the ladder would reach along the side of the building h, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

41² = 9² + h²

1681 = 81 + h²

h² = 1681 - 81 = 1600

h = √1600

h = 40 ft
