Children who came forward are numbered 4, 8, 12, 16, 20, 24 i.e. multiples of 4 ≤25  

Given that 25 kids are waiting in line to play a game. They are assigned numbers ranging from 1 to 25 to identify themselves. Then, every fourth child in line is asked to step forward.

Every fourth child in the line is asked to step forward

then, 4th child,8th child,12th child,16th child,20th child,24 child will come forward as if 4,8,12,16,20,24 are the numbers which are multiples of 4 ≤25

Children who came forward are numbered 4, 8, 12, 16, 20, 24 i.e. multiples of 4 ≤25

36% of 80

First, you multiply 36 and 80.

36*80 = 2880

Now, we divide that by 100.

2880/100 = 28.8

Our final answer: 28.8

Write as a mathematical expression. The product of 5 and x.Answer 5 + x
Reptile [31]
<h2>Answer:</h2>

<em>Question 1)</em>

                  5x

<em>Question 2)  </em>

                0.22a

<em>Question 3)</em>

                    8 + 6n  

<em>Question 4)</em>

                    25

<em>Question 5) </em>

                 ab+c=14

<h2>Step-by-step explanation:</h2>

<u>Ques 1)</u>

The product of 5 and x.

Product of two numbers means that it is obtained by multiplying them.

Hence, the expression so obtained is:   5x

<u>Ques 2)</u>

22% of a

It means that:

22%×a

Also, we know that:

22% =0.22

This means that:

22% of a=0.22×a

i.e.

22% of a=0.22a

<u>Ques 3)</u>

8 more than the product of 6 and n.

The product of 6 and n is given by: 6n

and 8 more than there product will be given by:

                             8+6n

<u>Ques 4)</u>

Evaluate: 30 − m/6 for m = 30

i.e. we put m=30 in the expression and get the resulting value.

i.e. we have:

30-m/6=30-(30/6)

i.e.

30-m/6=30-5

i.e.

30-m/6=25

<u>Ques 5)</u>

Evaluate ab + c for a= 2, b = 5, c = 4.

i.e. we will put the value of a,b and c in the given expression and find the value.

i.e.

2×5+4= 10+4

i.e.

ab+c=14

19. A carpenter is putting a skylight in the roof. If the roof measures (10x + 9) by (7x + 7) and the skylight measures (x + 5)
velikii [3]
19)  67x²+115x+48
20) (w+8)²
21) (d+11)²
22) (r+7)(r-7)

Explanation:
19)  The area of the ceiling is given by (10x+9)(7x+7).  Multiplying we have:
10x*7x+7*10x+9*7x+9*7
=70x²+70x+63x+63
=70x²+133x+63

The area of the skylight is given by (x+5)(3x+3).  Multiplying we have:
x*3x+3*x+5*3x+5*3
=3x²+3x+15x+15
=3x²+18x+15

To find the remaining area of the ceiling we subtract:
(70x²+133x+63)-(3x²+18x+15)
=70x²+133x+63-3x²-18x-15
=67x²+115x+48

20)  To factor, we want to find factors of c, 64, that sum to b, 16.  8*8=64 and 8+8=16; therefore we have:
(w+8)(w+8)
Since this is the same binomial twice, we write it as (w+8)²

21)  Again we look for factors of c, 121, that sum to b, 22.  11*11=121 and 11+11=22, so:
(d+11)(d+11)
Since this is the same binomial twice, we have (d+11)²

22)  Factors of -49 that sum to 0 (there is no r term, just r²):  -7*7=-49 and -7+7=0, so:
(r-7)(r+7)
