Each square on the grid represents 1 mi2. What is the approximate area of this park?







A.


about 35 mi² to 45 mi²


B.


about 55 mi² to 65 mi²


C.


about 75 m² to 85 m²

Answers

Answer:

Option (b) is correct.

The approximate area of this park is about 55 mi² to 65 mi².

Step-by-step explanation:

 Given : A grid with Each square on the grid represents 1 mi². and a park is constructed on it.

We have to determine the approximate area of this park.

We first find the area of grid and then subtract the uncovered square that are not covered  in park area.

Length of square grid is 10 mi and breadth is 8 mi.

So, area of square grid = 10 × 8 = 80 mi²

Number of uncovered squares that are not covered  in park area  = 9  squares

So Area of uncovered squares = 9 mi²

Maximum  area of park is (80 - 9) = 71 mi²

Also, Area of partially covered squares = 21 mi²

So, Minimum area of park is (80-30) = 50 mi²

Since, area of park lies in between 50 to 71

So , from  given options only (b) satisfies the approximate area of this park.

Thus, the approximate area of this park is about 55 mi² to 65 mi².
the answer is B.B.about 55 mi² to 65 mi² inside there are 50 squares plus the small square there is a total area of 59 mi^2

A jigsaw puzzle contains 50 pieces. If joining any two pieces or groups is considered one move, what is the least amount of moves to join all 50 pieces?

Answers

So, you see that when 2 pieces is considered a group, that means you have to divide. So, you divide 50/2 and it gives you 25.

a train traveled 1/5 of the distance between two cities in 3/4 of an hour. at this rate how's my hours will it take the train to travel the entire distNce between two cities?

Answers

The time that will be taken by the train to travel the entire distance between the two cities is 3 3/4 hour.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance Covered / Time taken

Let the complete distance be represented by d miles.

Given that the train traveled 1/5 of the distance between two cities in 3/4 of an hour. Therefore, we can write the speed of the train as,

Speed of the train = Distance / Time

                              = (d/5) miles / (3/4) hour

                              = 4d/15 miles per hour

Now, the time it will be taken by the train to complete the entire distance d, will be,

Time = Distance / Speed

Time = d miles / (4d/15)miles per hour

Time = 15/4 hour

Time = 3.75 hour

Time = 3 3/4 hour

Hence, the time that will be taken by the train to travel the entire distance between the two cities is 3 3/4 hour.

mary made a small pan of ziti and a small pan of lasagna. she cut the ziti into 8 equal parts and the lasagna into 9 equal parts. her family ate 2/3 of the lasagna. if her family ate more lasagna than ziti what fraction of the ziti could have been eaten?

Answers

Answer:

Hence, the possible fractions would be:

(1)/(8),(2)/(8),(3)/(8),(4)/(8),(5)/(8)

Step-by-step explanation:

" Mary made a small pan of ziti and a small pan of lasagna. she cut the ziti into 8 equal parts and the lasagna into 9 equal parts" .

Now her family ate 2/3 of the lasagna.

That means her family ate 6 lasanga. ( Since 2/3 of 9 parts is 6{ as (2\3)×9=6} ).

Now it is given that her family ate more lasagna than ziti.

i.e. her family would have eaten less than 6 ziti's.

I.e. they would have eaten either 1,2,3,4 or 5 ziti's.

Hence, the possible fractions would be:

(1)/(8),(2)/(8),(3)/(8),(4)/(8),(5)/(8)
Well, 2/3 times 9 is 6 parts of lasagna, so that means that the family must have eaten less than 6 piece of ziti; and 1/4 times 8 equals 2 parts of ziti...so 1/4 can be your answer!
