Answer:
Step-by-step explanation:
Angles Inside a Polygon
A polygon of n sides must have the sum of its internal angles
The polygon shown in the figure has n=5 sides, so the sum of its internal angles is
The construction of the internal angles of the polygon is shown in the image below. The sum of them is
Reducing
Solving
It is given in the question that,
The French club is holding a car wash fundraiser. They are going to charge $10 per car, and expect between 50 and 75 cars.
The cost depends on the number of cars washed .
So number of cars is the independent quantity and cost is the dependent quantity .
And here, let, y represents the cost and let x represents the number of cars.
So the domain is 50 to 75 cars.
And when x=50 and 75, value of y is
And the range is $500 to $750 .
So the correct option is B
We are given : The mass of a grain of sand =
Bag contains = 10 kilograms of sand.
Let us concert 10 kg into grams first.
1 kg = 1000 grams.
10 kg = 10 × 1000 = 10000 grams = 10^4.
Therefore, bag contains 10^4 grams of sand.
Therefore, number of grains of sand are in the bag of sand of 10^4 grams =
The mass of a grain of sand in grams ÷ The mass of a grain of sand.
=
=
Therefore, grains of sand are in the bag of 10kg sand.
