Answer:
Step-by-step explanation:
Your question isn't complete but let me help out based on the information given.
Joshua's recipe for chili requires 2 3/4 pounds of beef. Sondra's recipe for chili requires 2 2/3 pounds of beef.
The pounds of beef required by both of them will be:
= 2 3/4 + 2 2/3
= 2 9/12 + 2 8/12
= 4 17/12
= 4 + 1 5/12
= 5 5/12
The difference in the pounds of beef required by both of them will be:
= 2 3/4 - 2 2/3
= 2 9/12 - 2 8/12
= 1/12
Also, we.can also infer that Joshua recipe for chili requires more pounds of beef than that of Sondra
The average speed of Martha and Sarah is 32 km/h.
We need to know about the speed to solve this problem. Speed can be determined as the distance traveled divided by time. It can be written as
v = s / t
where v is speed, s is distance and t is time.
From the question above, we know that:
t sarah = 3 hours
t martha = 5 hours
v sarah = 40 km/h
By using the speed equation, we get the distance
vsarah = s / tsarah
40 = s/3
s = 120 km
Find Martha's speed
vmartha = s / tmartha
vmartha = 120 / 5
vmartha = 24 km/h
Find average speed
v = (vsarah + vmartha)/2
v = (40 + 24) / 2
v = 32 km/h
Hence, the average speed of Martha and Sarah is 32 km/h.

Answer:
f(t) = 5×0.87^t
Step-by-step explanation:
The general form for an exponential function described in this fashion is ...
... f(t) = (starting value) × (1 + (percent change))^t
Here, the "percent change" is -13%, or -0.13.
Then the value (1 + percent change) is (1 + (-0.13)) = 0.87. Putting this and the starting value into the form above, we have ...
... f(t) = 5 × 0.87^t
