Answer:

area of carpet = 19.25 m²

Step-by-step explanation:

given:

A room measuring 6m x 4m is carpeted leaving space of 25cm all around.

find:

the area of the carpet

--------------------------------

carpet is offset 0.25m all round.

area of carpet = (6 - 0.25 - 0.25) x (4 - 0.25 - 0.25)

area of carpet = 5.5 m x 3.5 m

area of carpet = 19.25 m²

Answer:

x = 2, -4

Step-by-step explanation:

To find the answer to this question, we will have to find the values of x where:

-5|x + 1| + 3 = -12

We can solve this equation for x to find the values of x that satisfy this equation.

-5|x + 1| + 3 = -12

Subtract 3 from both sides.

-5|x + 1| = -15

Divide both sides by -5.

|x + 1| = 3

Now here, the equation will split off into two different equations. These two are:

x + 1 = 3

x + 1 = -3

Lets solve the first one first.

x + 1 = 3

Subtract 1 from both sides.

x = 2

Now we solve the second one.

x + 1 = -3

Subtract 1 from both sides.

x = -4

So now we have the answers x = 2 and x = -4.

So the values of x are x = 2, -4

I hope this helps.

Answer:

-5, -7, and -12

Step-by-step explanation:

A function is defined as a relation between a set of inputs having one output each.

The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.

A function is defined as a relation between a set of inputs having one output each.

The inputs are called the domain of the function.

The outputs are called the range of the function.

We have,

A function r(x)

r(x) = x - 7

The value of r(x) at x = -2:

r(-2) = - ( -2) - 7

r(-2) = 2 - 7 = -5

The value of r(x) at x = 0:

r(0) = -0 - 7 = -7

The value of r(x) at x = -2:

r(5) = -5 - 7 = -12

We see that,

Domain = -2, 0, and 5.

Range = -5, -7, and -12.

Thus,

The values of the function r(x) at x = -2, 0 and 5 are -5, -7, and -12.

Answer:

-2

Step-by-step explanation:

6k=-24+12

or,6k=-12

or,k=-12/6

or,k=-2

Answer:

The value of k is -2.

Step-by-step explanation:

First, you have to add 12 to both side :

[tex]6k - 12 = - 24[/tex]

[tex]6k - 12 + 12 = - 24 + 12[/tex]

[tex]6k = - 12[/tex]

Next, you have to divide by 6 :

[tex] \frac{6k}{6} = \frac{ - 12}{6} [/tex]

[tex]k = - 2[/tex]

Answer:

y = 4x + 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = 8 , thus

y = 4x + 8 ← equation of line

The equation in slope-intercept form is y = 4x+8

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given that, a line has a y-intercept of 8 and a slope of 4.

We know that, the general equation of a line is given by, y = mx+c

where m is slope and c is the y intercept,

Here, m = 4 and c = 8

Therefore, the equation can be, y = 4x+8

Hence, The equation in slope-intercept form is y = 4x+8

Step-by-step explanation:

We can divide the number of raisins by 8 because there are 8 bags (680÷8) which would be 85. Next we multiply the 85 by 12 because we need to find out the number of raisins in 12 bags (85×12), which would give us 1,020.

Answer:

Step-by-step explanation:

First I took the original price of the shirt (46.50) since it is going one third off I divided it by 3 (46.50/3=15.50)

I took away the one third I divided from it (46.50-15.50=31)

I got 31 dollars as my final answer.

Now Karim needs to buy the shirt for $31.

Answer:

$31

Step-by-step explanation:

Price of the shirt normally: $46.50

Deduction in the price when it's 1/3 off: 1/3 * $46.50 = $15.50

amount that Karim needs to pay to buy the shirt:

Price of the shirt normally - Deduction in price when it's 1/3 off =

$46.50 - $15.50 = $31.00

Answer:

Step-by-step explanation:

60/15=4

The rate of change is 1/4 shovels/ minute of 0.25 shovels/ minute.

Rate of change is the increase or decrease of any property with respect to any other property, when rate of change is studied for a time duration, the ratio of the difference in the property from initial state to its value at the end of the time duration is divided by the total time.

For an expression, the rate of change is determined by differentiation.

The hardware store sold 15 shovels in sixty minutes.

The number of shovels sold is 15.

The time duration in which the shovels are sold is 60 minutes.

The rate of the shovels sold every minute has to be determined.

Rate = ( No. of shovels sold) / Time duration

Substituting the values

Rate = 15 /60

Rate = 1/4

Rate is 1 shovel sold every 4 minute.
