a. Chocolate need to cover a rectangle with a length of 9 in. and a perimeter of 22 inches is 18 pieces of 1 inch square piece chocolates

b.Chocolate need to cover a rectangle with a length of 5 in. and a perimeter of 20 inches is 20 pieces of 1 inch square piece chocolates

Step-by-step explanation

a. To cover a rectangle with a length of 9 in. and a perimeter of 22 in.

perimeter = 2(length+breadth)

Breadth = 22 -9×2 = 22-18 = 4 ÷ 2 = 2 inches

Area of rectangle = 9 × 2 = 18 inches

18 pieces of 1 inch square piece Chocolate is needed to cover the rectangle

b. To cover a rectangle with a length of 5 in. and a perimeter of 20 in.

perimeter = 2(length+breadth)

Breadth = 20 - 5 ×2 = 10 = 10 ÷ 2 = 5 inches

Area of rectangle = 5 × 5 = 20 inches

20 pieces of 1 inch square piece Chocolate is needed to cover the rectangle

You are designing an amusement park ride with cars that will spin in a circle around a center axis, and the cars are located at

Andrei [34K]

Answer:

144 people.

Step-by-step explanation:

Let n be the vertices, where cars are located.

We have been given that the sum of the measures of the angles' vertices is 6120°.

Let us find the number of vertices using formula:

$\text{Sum of all interior angles of a polygon with n sides}=180(n-2)$ .

Upon substituting the given sum of the measures of the angles in this formula we will get,

$6120=180(n-2)$

Using distributive property $a(b+c)=a*b+a*c$ we will get,

$6120=180n-360$

Adding 360 to both sides of our equation we will get,

$6120+360=180n-360+360$

$6480=180n$

Upon dividing both sides of our equation by 180 we will get,

$\frac{6480}{180}=\frac{180n}{180}$

$36=n$

As the cars are located on the vertices of regular polygon, so there will be 36 cars in the ride.

We are told that each car holds a maximum of 4 people, so the number of maximum people who can ride at one time will be equal to 4 times 36.

$\text{Maximum number of people who can be on the ride at one time}=4\times 36$

$\text{Maximum number of people who can be on the ride at one time}=144$

Therefore, the maximum number of people who can be on the ride at one time is 144 people.

Pls help I will mark braniliest

lidiya [134]

Answer:

y=x+2 will be a positive upwards graph that has a slope of 1 this means it will cross diagonally perfectly it won't change directions and it won't go up more than down or left more than right. It will cross the x axis at 2.

y=-x+2 It will be the same thing but this time starts from the top left and goes down gets to x axis at positive 2 again

y=|x|+2 This will go down from top left again and hit positive 2 on y axis then go back up making a v it does not curve and it does have a perfect slope of 1 making it easy to graph.
