For the question mark, we can insert a variable considering it is an unknown number.
Answer:
c
Step-by-step explanation:
To solve the equation we just substitute x with 7
so
5(7+3)
5*10
50
so the answer is c

Given:
hexagon
apothem of the hexagon: 14 cm
perimeter of the hexagon: 96 cm
Area of the hexagon = [(3√3) / 2] a² ; where a is the measure of the side
hexagon has 6 sides.
Perimeter = 6a
96 cm = 6a
96 cm / 6 = a
16 = a
We can also use the area of a triangle to approximate the area of the hexagon. There are 6 triangles in the hexagon .
Area of a triangle = (height * base) / 2
A = (14 cm * 16 cm) / 2
A = 224 / 2
A = 112 cm²
112 cm² * 6 triangles = 672 cm²
Answer
10
Step-by-step explanation:
salamander:frog
6:7
start by setting up the ratios as fractions and using <em>x</em> as the variable.
=
next cross multiply.
6x=63
x=10 i believe
You have to convert the fraction so the bottom number is 100
1900: 14/25=56/100
1910: 29/50=58/100
1920: 53/100
1930: 13/20= 65/100
1940: 3/5=60/100
Your answer would be 1930: 13/20= 60/100
