Answer:
70
Step-by-step explanation:
70+8,39*2; they all equal seventy two. Also, 0.78*100 works.
The distance from the original boat position to the bottom of the lighthouse is a. The boat travels x distance and ends up b distance from the bottom of the lighthouse.
tan 76.88333 = a/200
a = 200 tan 76.88333 = 858.3177
tan 39.3 = b/200
b = 200 tan 39.3 = 163.6981
x = a - b = 858.3177 - 163.6981 = 694.6196
Answer: 694.62 ft
The system of equations has no solution.
Solution:
Given expression –x + 5y = 5 and x – 5y = 5.
–x + 5y = 5 – – – – (1)
x – 5y = 5 – – – – (2)
Adding (1) and (2), we get
–x + 5y + x – 5y = 5 + 5
Combine like terms together.
(–x + x) + (5y – 5y) = 5 + 5
0 + 0 = 25
There is no x-term and y-term in Left hand side.
So, the system of equations has no solution.
8 ounces* 20 days= 160 ounces
160 ounces divided by 16 ounces in a pound= 10 pounds
She will have fed tiny 10 pounds of dog food in 20 days.
