We know that
In a period of 4 hours (3 hours of work and 1 hour to refuel)
each street sweepers clean------> 3 miles*3 =9 miles
divide 18 hours by 4
18/4=4.5
4.5 is equal to 4 periods of 4 hours plus 2 hours
Multiply 4 by 9 miles
4*9=36 miles
in the period of 2 hours (<span>in this period there is no refuel)
</span>3*2=6 miles
each street sweepers clean in 18 hours-----> (36+6)-----> 42 miles
two street sweepers clean in 18 hours=2*42------> 84 miles
the answer is
84 miles
The area of the trapezoid can be calculated through the equation,
A = (b₁ + b₂)h / 2
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,
A = (25mm + 32mm)(15 mm) / 2
A = 427.5 mm²
Since there are two trapezoids in the necklace, the area calculated is to be multiplied by two to get the total area.
total area = (427.5 mm²)(2)
<em>total area = 855 mm²</em>
Answer:
Option A will be the answer.
Step-by-step explanation:
The number of members, s(t), who joined the program t months after it was introduced is modeled by the function below
The function is an exponential function and y-intercept of the function is at (0,20) point.
Now, from the graph given in the options, the first graph matches the criteria.
Hence, option A will be the answer. (Answer)
