Answer:

Step-by-step explanation:
This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem. 

Where <em>a</em> and <em>b </em> are the legs of the triangle and <em>c</em> is the hypotenuse. 
In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values: 

Substitute these values into the formula. 

Solve the exponents. 


Add.

Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides. 

The third side length is <u>8.</u>

Answer:
(D)5
Step-by-step explanation:
Given the point J(-3,1) and K(8,11).
The line segment that divides the segment from J to K in any given ratio can be determined using the formula.

In the given case:
 , m:n=2:3
, m:n=2:3
Since we are to determine the y-coordinate of the point that divides JK into a ratio of 2:3, we have:

The y-coordinate of the point that divides the directed  line segment from J to K into a ratio of 2:3 is 5.
The correct option is D.
 
        
             
        
        
        
Answer:
121 inches squared
Step-by-step explanation:
If the dimensions are multiplied by 1/4, we have that the surface area will by multiplied by (1/4)^2, as the dimensions are in inches and the surface area is in inches squared.
So, If the original surface area is 1936 inches squared, the new surface area will be:
New surface area = 1936 * (1/4)^2 = 1936 / 16 = 121 inches squared.
