Answer:
Step-by-step explanation:
10 feet............................6 seconds
?......................................45 seconds
? feet=10*45/6=75 feet
75 feet in 45 seconds
It looks like you're trying to solve
3x₁ + 7x₂ + s₁ = 49
x₁ +4x₂ +s₂ = 31
Fill in the given values for x₁ and s₁ and your system reduces to
7x₂ = 49
4x₂ +s₂ = 31
The first of these equations tells you x₂ = 49/7 = 7, so the second equation becomes
28 +s₂ = 31
and it is immediately obvious that s₂ = 3
Your solution is (x₁, x₂, s₁, s₂) = (0, 7, 0, 3).
Answer:
The answer is
<h2>126 feet</h2>
Step-by-step explanation:
Circumference of a circle is πd
Where d is the diameter
From the question
d = 40 feet
Circumference of the circle is
40π
= 125.66
= 126 feet to the nearest whole number

Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
