Answer:
10 km / hr
Step-by-step explanation:
Speed of boat = 15 km /hr
Speed of stream = 5km /hr .
Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr
Answer:
x = 6
y = 3
Step-by-step explanation:
Give triangle is a right triangle.
By applying sine ratio in the given triangle,
sin(60)° = 

x = 6
Now we take the cosine ratio in the given triangle,
cos(60)° = 

y = 
y = 
Therefore, x = 6 and y = 3 will be the answer.
Answer: 6x + 24
Explanation: In this problem, the 6 "distributes" through the parenthses, which means that it multiplies by each of the terms inside.
So we have 6(x) + 6(4) which simplifies to 6x + 24.
Given:
Total price : 107,820
down payment 15% of the total price.
financing the remainder at 6.5% for 25 years.
How much is she financing? She will finance 85% of the total price.
107,820 * 15% = 16,173
107,820 - 16,173 = 91,647
or
107,820 * (100-15)% = 107,820 * 85% = 91,647
