Answer:
27.8 Celsius
Step-by-step explanation:
The equation to convert Fahrenheit and Celsius is:
F = (9/5)C + 32
82 = (9/5)C + 32 -- subtract 32 from both sides
50 = (9/5)C -- multiply both sides by 5
250 = 9C -- divide by 9
27.777 = C
round up to 27.8 C
(9/6) = (15/?)
9? = 90
? = 10
Answer:
yes
Step-by-step explanation:
y=-16r^2+63r+4
maximum value of y :
y'=0
-32r +63=0
r= 63/32
y = -16(63/32)²+63(63/32)+4
= -4 + 124 + 4 = 124 ft
124 > 68
the Arrow can pass over the tree
One gallon is equivalent to 128 fluid ounces
3 gallons is equivalent to 3*128 fluid ounces
= 384 fluid ounces
One plastic cup can hold 12 guide ounces
So cups needed will be 384/12
32 cups
