30 girls , 12 were selected

40 boys, 16 were selected

We can simplify these down by finding the Greatest Common Factor in both girls and boys:

30:12 .... 15:6 .... 1 : 2.5 30/12 .... 15/6 .... 2.5

40:16 .... 20:8 .... 1 : 2.5 OR 40/16 .... 20/8 .... 2.5

They are equal ratios because their most simplified ratios/fractions are equivalent

chubhunter [2.5K]

Answer:

2 chairs will be left over.

Step-by-step explanation:

Given that

There are a total of 1492 chairs.

which are to divided in 10 rows evenly.

To find:

Number of chairs left ?

Solution:

Let the number of chairs in each row = x

There are 10 rows so number of chairs in rows = 10x

Let the number of chairs left = y

Total number of chairs =10x + y  = 1492

The above equation is like:

Divisor \times Quotient + Remainder = Dividend

So, we have to find the remainder in this question where we are given Divisor and Dividend.

10 \times 149 + 2 = 1492

So, dividing 1492 with 10, we get remainder as 2.

Hence, 2 chairs will be left.

Let S = {1, 4, 6, 9}
tankabanditka [31]

Answer:

There are 8 sets B that satisfy the conditions.

Step-by-step explanation:

We have to find the total subsets of S that have 1 as an element.

Subsets B with one element: {1}

Subsets with two elements: {1,4}, {1,6}, {1, 9}

Subsets with three elements: {1,4,6}, {1,4,9}{1,6,9}

Subsets with four elements: {1,4,6,9}

Therefore, B = {1, {1,4}, {1,6}, {1, 9}, {1,4,6}, {1,4,9}, {1,6,9}, {1,4,6,9}}
