Answer=1/24
1/3+5/8=
to solve for this, we need the denominators of the fractions to match.
The LCM of 3 and 8 is 24
1/3=8/24
5/8=15/24
8/24+15/24=23/24
Now if we're using 23/24, then only 1/24 is left.
24/24-23/24=1/24
Answer:
2.6779*10^5
Step-by-step explanation:
The problem given is 2.69*10^5 - 1.21*10^3 which is 269000-1210=267790 -> 2.6779*10^5
T(t) = Ts + (T₀ - Ts)exp(-kt), substituting the values:
60 = 50 + (80 - 50)exp(-25k)
10/30 = exp(-25k)
k = 0.0439 °C/min
Answer:
You will need 7 large and 28 small stones.
Step-by-step explanation:
x = the number of large stones
y = the number of small stones
x + y = 35
for every large stone, you want to use 4 small stones:
y = 4x
by solving the system of equations:
x + y = 35
y = 4x
we find:
x = 7 large stones
y = 28 small stones
All you have to do is 4 times 2 which is 8. So it's 8 square inches.
