The area of a trapezoid is the height times the average of its parallel bases.
A=h(b1+b2)/2, in this case
A=14(4.6+8.7)/2
A=7(4.6+8.7)
A=7(13.3)
A=93.1 km^2

El 35 % de los estudiantes de un centro docente practica el fútbol. El 70 % de los que practican el fútbol estudia Matemáticas, así como el 25 % de los que no practican el fútbol
Answers
Answer:
El 40.75% de los alumnos del centro docente estudian matemáticas.
Step-by-step explanation:
Dado que el 35 % de los estudiantes de un centro docente practica el fútbol, y el 70 % de los que practican el fútbol estudia Matemáticas, así como el 25 % de los que no practican el fútbol, para determinar los porcentajes de estudiantes de matemáticas en el centro docente se debe realizar el siguiente calculo, suponiendo que el total de alumnos del centro sea 100:
35 x 70 / 100 = 2,450 / 100 = 24.5%
100 - 35 = 65
65 x 25 / 100 = 1,625 / 100 = 16.25%
24.5 + 16.25 = 40.75
Así, el 40.75% de los alumnos del centro docente estudian matemáticas.

Dirk bought a set of stamps. The number of stamps in the set he bought is divisible by 2, 3, 5, 6, and 9. Which set is it?
Answers
Answer:
Germany - 90
Step-by-step explanation:
Here are the options to this question
Germany 90
Sweden 78
Japan 63
Canada 75
The appropriate answer should be a multiple of 2, 3, 5, 6, and 9. That is when the number is divided by 2, 3, 5, 6, and 9 it should have a remainder of zero.
90 / 2 = 45
90 / 3 = 30
90 / 5 = 18
90 / 6 = 15
90 / 9 = 10
Thus, the appropriate number is 90
When 78 is divided by 5 and 9, the remainder is not zero
When 63 is divided by 2, 5 and 6, the remainder is not zero
When 75 is divided by 2, 3, 6 and 9, the remainder is not zero
The length of a rectangle can be represented by the expression (2 - 1) and the width can be

PLS HELP ME AND IF YOU CAN SHOW HOW U GOT THE ANSWER IF NOT THATS OKAY!!! ILL ALSO MARK YOU BRANLIEST IF YOU HELPED ME!!! <333
Answers
Answer:
Step-by-step explanation:
The length is (x-1), not (2-1).
area = (x-1)(x+3) = 12 ft²
x²+2x-3 = 12
x²+2x-15 = 0
(x+5)(x-3) = 0
x = -5, 3
-5 is an extraneous solution, so x=3.
Length = x-1 = 2 feet
Width = x+3 = 6 feet

Find the area of the shaded part of the triangle below. Round to the nearest tenth if needed.
Answers
Answer:
212.5
Step-by-step explanation:
For triangles, A = (bh)/2
You can do 15+25 to find the base, which is 40. From here do 17*40/2. You get 340. However, you need to remove the right triangle on the left side.
Again do 17*15/2, which you get 127.5.
From here subtract 127.5 from 340 and get 212.5

A
16in.3
B
96in.3
C
192in.3
D
576in.3
Answers
It’s D because if you multiply each side of the object (How to determine volume) then divide by six (because they want the volume of just one square and there is six squares) Then you get 576
Volume of the single prism will be : 576 inches
What is a Rectangular Prism ?
In geometry a Rectangular prism is a polyhedron with two congruent and parallel bases. It has six faces and have twelve edges.
Volume of a Rectangular prism = L * B * H
= 24 * 6 * 24
= 3456 inch^3
Since , it consists of six identical Rectangular prisms
Volume of single prism will be = 3456 / 6
