1-jamie has 875 building pieces in all. he gives his castle set to a friend. jamie then buys the helicopter set. how many building pieces does jamie have now? castle 257 pieces helicopter 229 pieces 2-make sense and persevere how can you estimate to check if your answer is reasonable? explain

Answer 1:

Total pieces left with Jamie  = 618

Step-by-step explanation:

Given in the question is that Jamies has eight hundred and seventy-five building pieces. Out of that, he gave two hundred and fifty-seven pieces to his friend. Though after giving some pieces to his friend he bought two hundred and twenty-nine helicopters. Now to calculate the total number of pieces left with Jamie we need to minus the given from the obtained building pieces.

Total number of building pieces he has = 875

Number of castle pieces that he gave to a friend = - 257

Total pieces left with Jamie  = 618

Answer 2:

As asked, yes it does make sense that the number of building pieces left with Jamie is six hundred and eighteen. To find a number of building pieces that he has left we had subtracted the total number of buildings to the number of castles gave equal the to a number of pieces left. Therefore, we put the values of total building pieces equal to 875,  pieces of castle equal to 257  and finally we get the number of pieces left of building a puzzle that is 618. This proof the solution of the question and makes perfect sense for the reasoning.        

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
