Answer:

13 feet

Step-by-step explanation:

the part of the ladder on the ground creates a right angle with the building where the base is 7 feet and the hypotenuse is 15 feet

we can use the pythagorean theorem to solve for the height of the building

let 'b' = height of building

7² + b² = 15²

49 + b² = 225

b² = 176

b = \sqrt{176}

\sqrt{176} = \sqrt{4}\sqrt{4}\sqrt{11} = 2·2\sqrt{11}

b = 4\sqrt{11} which is approximately 13.3 feet

Alex777 [14]
Hello! In order to understand this question, we need to take a look at the content that is involved.

Lupita pays $40.03 in total. Meaning that's where we are going to start if we want to find out how many miles her ride was. Since the taxi charges a flat rate of $6.75. We would want to subtract it from her total value because we only work with that flat rate once. Which ends up giving us $33.28. From there, we don't need to worry about the flat rate anymore and we now focus on the mileage. If it costs $3.20 per mile, then we can simply divide the amount after to flat rate by the cost per mile, to figure out how many miles she has gone. In the end, you will get 10.4 miles.

List the fractions and decimals in order from least to greatest: -0.6,-5/8,-7/17,-0.72
zhuklara [117]
First, let's convert all of these numbers to decimal form:

(This will make it much easier to compare.)

- 0.6, - 0.625, - 0.4117, - 0.72

Now we can list them from least to greatest!

-0.4117, - 0.6, -0.625, -0.72

And don't forget to convert the selective decimals that we converted earlier back into fractions!

Therefore, the final list would be:
- 7/17, - 0.6, - 5/8, - 0.72

Hope this helps!

(x-5)1/2+5=2<br> (x-5)1/2=-3<br> [(x-5)^1/2]^2=(-3)^2
Studentka2010 [4]

Answer:

x = 14

Step-by-step explanation:

You want to solve for x, right?

(x-5)^(1/2)+5=2

You have it right so far.

(x - 5)^(1/2) = -3

(x - 5)  =  (-3)^2

x - 5 = 9

x = 9 + 5 = 14
