A base ball diamond is square.The distance from home plate to first base is 90 feet.what is the distance from home plate to seco
Elena-2011 [213]

Because it is square, the distance from home to first base is the same as first base to second base.


Home to First is one side of a right triangle, first to second is the second side of the right triangle and then home to second base would be the hypotenuse of a right triangle.


Using the Pythagorean Theorem we can solve for the hypotenuse:

Let C = the hypotenuse:

90^2 + 90^2 = c^2

8100 + 8100 = c^2

16200 = c^2

c = √16200

c = 127.279 feet, round to 127 feet.

How many degrees is angle x
agasfer [191]

Answer:

The degrees of angle x is 180 degrees.

Step-by-step explanation:

Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of x.

(b) Simple random Sample:

This sample is formed by the random and unbiased selection of individual that represents the population.

(c) Population:

The entire set of individuals with certain specific characteristics represents a population whereas a sample is drawn out of the population and can be referred to as the subset of the population.

(d) Cluster Sample:

In this, separate sample groups are formed known as clusters, here sampling of random clusters take place.

When the smaller of two consecutive integers is added to to two times the​ larger, the result is 29
KengaRu [80]
Let the numbers be X and X+1. X+2(X+1)=29 X+2X+2=29 3X=29-2 X=27/3 X=9. Thus, the Numbers are therefore 9 and 9+1=10 i.e 9 & 10. Thus, when 9 is added to (2*10=20), the result is 29.
