A little boy saved nickels and dimes. He had 8 more nickels than dimes. The total of his money was $1.45. How many nickels and h
gladu [14]
N=8+d
10d+5n=145
divide 2nd equaiton by 5 to make nicer and easier
2d+n=29

subsitute 8+d for n in 2nd equation
2d+8+d=29
3d+8=29
minus 8 both sides
3d=21
divide by 3
d=7
sub back
n=8+d
n=8+7
n=15


15 nickles and 7 dimes

A regular hexagon is inscribed in a circle and another regular hexagon is circumscribed about the same circle. What is the ratio
Anna007 [38]

4/3 of the area of the larger hexagon to the area of the smaller hexagon

Let the sides of the interior hexagon be 2 cm long, then this hexagon is made up of 6 equilateral triangles of side = 2.

The area of this hexagon = 6 * 1 * sqrt3 = 6 sqrt3 ( as the triangle is made up of 2 60-30-90 triangles)

The exterior hexagon is made up of 6 equilateral triangles with altitude 2 and the area = 6 * 2 * (2 / sqrt3 ) = 24 / sqrt3

area exterior hex / interior hex = 24 / sqrt3 * 1 / 6sqrt3 = 24/18

= 4/3

Required ratio = 4/3 answer

The function f is given by f(x) = 10x + 3 and the function g is given by g(x) = 2×. for each question, show your reasoning
anzhelika [568]

Answer:

i got you :D

Step-by-step explanation:

f(x)= 2x²+4x-6 and g(x)=2x-2, find each function

1. (f/g) (x) = f(x)÷g(x) = (2x²+4x-6)÷(2x-2)

First factor both top and bottom:

(2x-2)(x+3)÷(2x-2) = x+3

2. f(a + 2) = plug (a+2) in anywhere there is an x in f(x)=2x²+4x-6 -->

2(a+2)^2 +4(a+2)-6 = 2(a^2+4a+4)+4a+8-6, now distribute:

2a^2+8a+8+4a+2, combine like terms

2a^2+12a+10
