Answer:

(i)The length of room = 5.5 m and width of the room = 4 m

The length of room with verandah = 5.5 + 2.25 + 2.25 = 10 m

The width of room with verandah = 4 + 2.25 + 2.25 = 8.5 m

Area of verandah = Area of room with verandah – Area of room without verandah = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (10 x 8.5) – (5.5 x 4) = 85 – 22 = 63 m2

(ii) The cost of cementing 1 m2 the floor of verandah = Rs 200 The cost of cementing 63 m2 the floor of verandah = 200 x 63 = Rs 12,600

Answer:

373737373737373383847484

This equation is in the form y = mx + b and when a function

is written in this form, we know that it's a linear function.

Another way to tell that it's a linear function is

that the variable is raised to the first power.

Answer:

3 days

Step-by-step explanation:

First, let's convert 400 meters to km (kilometers):

To find km from m we divide the meters by 1000:

400/1000 = 0.4

Therefore, there are 0.4 km in 1 meter.

Kali runs 10 laps every day, since 1 lap is 0.4 km we can multiply 10 by 0.4 to see how many kilometers they run in 1 day:

(10)(0.4) = 4

Kali runs 4 kilometers every day

Now, we can find how long it will take Kali to run a total of 12 kilometers by dividing 12 by 4

12/4 = 3

It will take Kali 3 days to run a total of 12 kilometers.

Answer: t1 = -34; t2 = -64; t3 = -94

d is the distance between numbers (d > 0)

we have:

t5 = t1 + 4d = -154

t9 = t1 + 8d = -274

we have the equations:

t1 + 4d = -154

t1 + 8d = -274

<=> t1 = -34

      d = -30

with t1 = -34 and = -30 => t2 = -34 - 30 = -64

                                          t3 = -64 - 30 = -94

Step-by-step explanation:

LET THE THREE CONSECUTIVE EVEN INTEGERS BE

(x+2) ,(x+4) ,(x+6)

then

according to the question

4(x+2) – (x+6) = 2(x+4) + 6

4x + 8 – x – 6= 2x + 8+6

3x +2 = 2x + 14

3x – 2x= 14 –2

x= 12

the numbers are

14

16

18

Answer:

The three numbers are 14, 16, 18.

Step-by-step explanation:

Consecutive even integers differ by 2.

You can let the smallest of the three numbers equal x. Then the other two numbers are x + 2 and x + 4.

Now use x, x + 2,and x + 4 to represent the 3 numbers and follow the directions to write an equation. The equation will have only one variable, x, so you can solve for x.

"four times the first" ----->   4x

"minus the third"   ------->    -(x + 4)

"is"  ----->     =

"six more than twice the second"   ------>    2(x + 2) + 6

Put all the pieces in boldface together to arrive at your equation.

4x - (x + 4) = 2(x + 2) + 6

Simplify the parentheses on both sides by distributing.

4x - x - 4 = 2x + 4 + 6

Combine like terms on both sides.

3x - 4 = 2x + 10

Subtract 2x from both sides.

x - 4 = 10

Add 4 to both sides.

x = 14

The smallest number is 14.

x + 2 = 14 + 2 = 16

x + 4 = 14 + 4 = 18

Answer: The three numbers are 14, 16, 18.

Answer:

Day 1=15 Day 2=30 Day 3=45 Day 4= 60 Day 5= 75. The expression is N+15

Step-by-step explanation:

The complete table:

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of bacteria samples analyze each day = 15

The equation for the number of bacteria analyzes after x days.

B = 15x

Now,

x = 1, B = 15

x = 2, B = 30

x = 3, B = 45

x = 4, B = 60

x = 5, B = 75

Thus,

Days                  1    2     3    4     5

Total samples  15  30  45  60   75

#SPJ5

Step-by-step explanation:

Given

f(x) = 5 / 2x - 1

f^-1( x) = ?

Let

y = f(x)

y = 5/2x - 1

Interchanging the roles of x and y we get

x = 5/2y - 1

2y - 1 = 5/x

2y = 5/x - 1

y = (5/x - 1)/ 2

f^-1(x) = ( 5/x - 1) / 2

Answer:

b = 12

Step-by-step explanation:

First, distribute 3/4 to both terms in the parentheses:

3 = 3/4(b - 8)

3 = 3/4b - 6

Now, solve for b:

9 = 3/4b

12 = b

So, the answer is b = 12

Answer:

12

Step-by-step explanation:

3 = 3/4 x (b-8)

Distribute 3/4 through the parentheses

3 = 3/4 b - 6

Multiply both sides of the equation by 4

12 = 3b - 24

Move the variable to the left - hand side and change its sign

-3b = -24 - 12

Calculate the difference

-3b = -36

Divide both sides of the equation by -3

B = 12

Answer:

8.5

Step-by-step explanation:

Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:

2(x-6)=5

(x-6)=5/2

x=6+5/2

x=17/2

So the number is 17/2, or, expressed as a decimal number, 8.5

Answer: A. 2 Decals

Step-by-step explanation: time4learning

The requried Dominic can buy a maximum of 2 decals.

Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve.

Dominic has $40 to spend, and he will spend $22 for the ticket and $7 for the parking. So, he will have:

$40 - $22 - $7 = $11

left to spend on team window decals.

Each decal costs $4.50, so we can divide the amount Dominic has left by the cost of each decal to find the maximum number of decals he can buy:

$11 ÷ $4.50 ≈ 2.44

Since we can't buy a fraction of a decal, we need to round down to the nearest whole number. So, Dominic can buy a maximum of 2 decals.

Therefore, the answer is A, 2 decals.
