Answer:
725 Boxes of Popcorn
Step-by-step explanation:
You can do it simply by just typing in the calculator 4893.75÷6.75.
But I can show my work. Picture below
Answer:
2.802691 revolutions per second
Step-by-step explanation:
You can round to the nearest whole number making it 3 revolutions per second
A: you need to know how many cars you wash an hour. A reasonable amount would be five cars an hour making the equation 24•5=120$
B: you need to know how much the baking molds cost, a reasonable amount would be 7.50, the equation would be 7.50•5=37.5
Hope this helps

Answer:
Step-by-step explanation:
For a triangle the area is

If our triangle is isosceles and the 2 congruent sides each measure 4 and they include an angle of 40 degrees, let's say that the vertex angle is 40 and the sides that are not the base each measure 4. If we drop an altitude from the vertex to the base, we cut the triangle into 2 right triangles, with the vertex angle being 20 degrees and the hypotenuse being 4. To find the base, then, which is opposite the angle, we use the sin ratio:
and
4sin(20) = b so
b = 1.368
But we need the whole base, and that is only half of it. So
2b = 2.736
To find the height, which is adjacent to the angle, we use the cos ratio:
and
4cos(20) = h so
h = 3.759
Now we have enough info to find the area of the triangle using the triangle area formula from above:
and
A = 5 meters squared.
