Mathematics

Paul [167]2 years ago

Answer:

24 ft

Step-by-step explanation:

a^2 + b^2 = c^2

7^2 + b^2 = 25^2

7^2 - 25^2 = -b^2

49 - 625 = -b^2

-576 = -b^2

24 = b

A survey of 100 high school students provided this
HACTEHA [7]

Answer:

35/100

Step-by-step explanation:

You have to find how many juniors there are, so if you add 13, 20, and 2 you get 35. For the denominator you have to find the total number of students, so just add all of the numbers together to get 100. So there is a 35/100 chance that a randomly selected student is a junior.

Image a coordinate plane with points plotted at ordered pairs Q(-4,4) R(2,4) S(5,-3) T(2,-3) and U (-4,-3) what is the area of t
pogonyaev

In counterclockwise order that's


R(2,4), Q(-4,4), U(-4,3), T(2,-3), S(5,-3)


That's a trapezoid, height 7 upper base 6, lower base 9, so average base 15/2 and area 7(15)/2 = 105/2 = 52.5.


Answer: 52.5


The shoelace theorem gives the answer without thinking. We write the list on top of itself shifted and add up the cross produces:


R(2,4), Q(-4,4), U(-4,-3), T(2,-3), S(5,-3)

Q(-4,4), U(-4,-3), T(2,-3), S(5,-3), R(2,4),


A = \frac 1 2 | 2(4)-(4)(-4) + -4(-3)-(-4)(4) + -4(-3)- -3(2) + 2(-3)-(-3)(5) + 5(4)- -3(2)| = \frac{105}{2} \quad\checkmark
