1. No, because the ratio 8:5 could be simplified from any factor of thirteen. 26 students in the class with 16 boys and 10 girls has the same ratio as 39 students in a class with 24 boys and 15 girls. So no, there is no accurate way to determine the number of students with the given information.
2. You can determine whether or not 2 ratios are equivalent if they can simplify to the same ratio. Using the first question as an example, 8:5 and 16:10 are the same ratio, because when you simplify the fraction 16/10, it is 8/5.

To hang lights up on his house.Garrett place is a 14 foot ladder 4 feet from the base of the house. How high up the house will t
Firlakuza [10]

This seems like a right triangle problem.

So assuming 14 feet is the hypotenuse and 4 feet is a leg of the right triangle, we can use the pythagorean theorem (a^{2} +b^{2} =c^{2}) to solve for the height of the house, in which we shall name it x.

So, the equation is 4^{2} +x^{2} =14^{2}.

Solve for x:

16+x^{2}= 196

x^{2}= 196-16

x^{2}= 180

x = 6√5 feet


Hope this helps!

Assuming Earth to be a sphere of radius 4000 miles, how many miles north of the Equator is City A, if it is 36° north from the E
vredina [299]

Answer:

2513 miles

Explanation:

\sf Length \ of \ arc = \dfrac{\theta}{360} * 2\pi r

Here given:

∅ = 36°

radius = 4000 miles

Insert following:

\sf \rightarrow  \dfrac{36}{360} * 2\pi (4000)

\sf \rightarrow  800\pi \  \ \ (in \ terms \ of \ \pi )

\sf \rightarrow  2513.3 \ \ (rounded \ to \ nearest \ tenth)

\sf \rightarrow  2513 \ \ (rounded \ to \ nearest \ mile)
