Answer:
B. 30.25 feet
Step-by-step explanation:
If the object is shot straight up at velocity v from the zero-height reference level, and if the effect of gravity (g) is a downward acceleration of 32 ft/s², then the height is given by ...
... h = v²/(2g) = (44 ft/s)²/(2·32 ft/s²)
... h = 30.25 ft
Answer:
they sold 210 hot chocolates and 85 coffees
Step-by-step explanation:
We know that they sold $200 worth of drinks
x will be the number of hot chocolates sold
y will be the number of coffees sold
This means that
.75x+.5y=200
We also know that they sold 295 total drinks which means that
x+y=295
This is a system of linear equations which I will solve through substitution
x+y=295
Subtract y from both sides and divide by -1 to get
-x+295=y
Plug y into the first equation and get
.75x+.5(-x+295)=200
Distribute the .5 and simplify to get
.75x-.5x+147.5
.25x+147.5=200
Subtract 147.5 and then divide by .25 to get our x value
x=210
Now we can go back and plug this in into our equation
210+y=295
Subtract 210 to get y
y=85
This means that they sold 210 hot chocolates and 85 coffees
Answer:
835
Step-by-step explanation:
We know that the hundreds is 8 and the ones is 5 so the sum needed is 16-(8+5), which equals 3 :)
2 - 12 = -10
the answer is -10 degrees celsius
