Answer:
6 hot dogs, 2 drinks
Step-by-step explanation:
let y = number of hot dogs
let x = number of drinks
system:
y = 3x
4.5y + 2.25x = 31.50 (standard form: y = -1/2x + 7)
if you graph the system, lines intersect at (2, 6)
2, sin( θ )=6/12=1/2 => theta=30 degrees.
=> triangle is 30-60-90
3.
Cos(45)=sqrt(2)/2
=> x=10*sqrt(2)/2=5sqrt(2)
Answer:
this is simple... 1 3/4
Step-by-step explanation:
Answer:
For 
we will have positive values only.
Rest are positive so will give positive values out of the modulus function.
Step-by-step explanation:
The absolute value of any number is its positive value only.
As for example 
and 
both are having equal distance from 
in a number line, one on the left other on the right side of the number line but are equidistant from .
So absolute value of a number is its distance on number line from reference point .
One by one we will work with all of our question.
So we have to take the positive number out of the modulus function that is also called absolute value.
Answer:
10000 metres
Step-by-step explanation:
You calculate by multiplying the number of metres in the ratio by 10 centimetres.
Your answer should come out to 10000 (10:10000)
