Step-by-step explanation:
Let's say b is the rate of the boat in still water, and c is the rate of the current.
Distance = rate × time
Going upstream:
100 = (b − c) (5)
20 = b − c
Going downstream:
100 = (b + c) (2)
50 = b + c
Solve the system of equations using substitution or elimination. Using elimination, add the equations together:
70 = 2b
b = 35
c = 15
The boat's speed is 35 km/h, and the current's speed is 15 km/h.
Your choices are correct.
1. adding -3 to the function shifts its graph downward by 3 units.
2. 7^(2x) = (7^2)^x = 49^x
3. f(0) = -6; g(0) = -3, f(0) = 2×g(0)
the answer would be 10 because you have to times by 2.5 on both sides to get t on its own.
4 × 2.5 is 10
Answer:
6 baskets did Kiran score on Thursday
Step-by-step explanation:
As per the statement:
Kiran scored 36 baskets in 1 week.
On weekend she scored =
baskets.
She scored 1/4 of them on Tuesday
⇒On Tuesday she scored =
baskets
She scored 1/12 of them on Wednesday
⇒On Wednesday she scored =
baskets.
Then;
She scored = On Weekend + On Tuesday + On Wednesday = 18+9+3 = 30 baskets.
Rest on Thursday she scored = 36 - 30 = 6 baskets.
Therefore, 6 baskets did Kiran score on Thursday
