Step-by-step explanation:
the money that Shelly will owe after buying x sandwiches and using the card will be:
if x < 4 then 15 - 4.5x <= 15 - 3*4.5 = 1.5 she will not owe anything plus she will receive change of $1.5.
if x=> 4 then 4.5x - 15 => 18 - 15 = 3 that is Shelly will owe 4.5x - 15 dollars.
Step-by-step explanation:
The question missing attachment (incomplete)
But the question said how far up does the ladder reach on the building?
See the attachment
Let the tita be 60° and the height of the building be 50 meters
Now
Opposite/hypotenuse = sin(tita)
50/x = sin60°
Cross multiply to find x
x = 50/sin(60°)
x= 50/0.8660
x=57.7 meters
Wouldn’t the answer be 40 be cause you multiply?
Answer:4 hours
Step-by-step explanation:
You multiply 8 by 120 and you get 960 miles per 2hrs
