Answer:
$12
Step-by-step explanation:
assuming that the cost of delivery is constant irrespective of the number ordered
Let the cost of sandwich be x
First office
$33=4x+c where c is the cost of delivery
Second office
$61=8x+c
These two are simultaneous equation. Subtracting the equation of first office from the second office we obtain
4x=28
Therefore, x=28/4=7
The cost of delivery is 33-(4*7)=33-28=5
Therefore, one sandwich plus delivery costs 7+5=$12
Answer:
Because 0 counts as the first possible number. 0-9 gives you 10 possible numbers.

because, u add them and then divide by 3 and that is ur answer
The solution of cos θ = −0.3 is θ = 107.45760312 degrees
<em><u>Solution:</u></em>
Given that we have to find the primary solution of 
To solve this equation, you must find the unknown (theta)

Use the inverse of cosine (Arccos) to find the angle measurement (in degrees) of theta

We know that arccos (-0.3) = 107.45760312 degrees
[ If you reference a unit circle or use a calculator ]

Therefore solution of cos θ = −0.3 is θ = 107.45760312 degrees
