Answer:
ticket in Japan: 17.23 $
ticket in Switzerland: 13.26 $
Step-by-step explanation:
let the price of one movie ticket in Switzerland be Y
let the price of one movie ticket in Japan be X
then accordingly,
it is given that
3x + 2y = 78.21
and
2x +3y = 74.24
multiplying the first equation by 2 and second by 3 we get
6x + 4y = 156.42
6x + 9y = 222.72
subtracting 1st equation from second we get
5y = 66.3
y = 13.26
by putting in the value of y in equation 2 we get:
2x + 39.78 = 74.24
2x= 34.46
x= 17.23
Hello!
To solve this we have to find what 82% of 50 is
So we do 50 * 0.82 where 0.82 is 82% as a decimal.
This gives us 41
So the answer is D
Hope this helps!
Let x = the width
then
2x = the length
:
The box dimensions: 2x by x by 4
Given the surface area:
2(2x*x) + 2(2x*4) + 2(x*4) = 220
:
4x^2 + 16x + 8x = 220
A quadratic equation:
4x^2 + 24x - 220 = 0
simplify, divide by 4
x^2 + 6x - 55 = 0
Factor
(x+11)(x-5) = 0
The positive solution is what we want here:
x = 5 ft is the width
then
2(5) = 10 ft is the length
:
Find the volume
10 * 5 * 4 = 200 cu/ft is the volume
Angle PQR=90 degrees.
cos 52=PQ/14.72
PQ=14.72 x (cos 52)
PQ= 9 cm to the nearest cm
