Answer:A)Y =k x

               Y =5x

              B.Y=60

Step-by-step explanation:

Given that Y is directly proportional to x

mathematically , it Is represented as

Y ∝ x

Introducing the constant of proportionality, k. we have that

Y =k x

Now when y=30, x=6, k becomes

30=k 6

k=30/6=5

we now have the equation connecting them as

Y =5x

B) Now when x=12, y becomes

Y =5x

Y =5 X 12

Y=60

975 toffees are to be distributed among 23 children. Estimate the numbers of toffees that each child will get in nearest tens.
Aneli [31]

Answer:

40

Step-by-step explanation:

Total number of toffees = 975

Total number of children = 23

Estimate the numbers of toffees that each child will get in nearest tens.

Number of toffees each child get = Total number of toffees / Total number of children

= 975 / 23

= 42.391304347826

Approximately,

Number of toffees each child get = 40 to the nearest tens

The large square below has a side length of 8 inches, and the smaller white square inside the large square has a side length of
9966 [12]
The image is not attached with, but by reading the question it is obvious that the blue region lies inside the larger square and outside the smaller square. That is the region between the two squares is the blue region.

We know the dimensions of both squares, using which we can find the area of both squares. Subtracting the area of smaller square from larger one, we can find the area of blue square and further we can find the said probability.

Area of larger square = 8 x 8 = 64 in² 
Area of smaller square = 2 x 2 = 4 in²
Area of blue region = 64 - 4 = 60 in²

The probability that a randomly chosen point lies within the blue region = Area of blue region/Total area available

Therefore, the probability that a point chosen at random is in the blue region = 60/64 = 0.9375
