Mr Cole made this diagram of his bedroom. Which is the area of Mr. Cole's bedroom?
10 ft
5 ft
4 ft
8 ft
A 90 square feet
B 82 square feet
c 72 square feet
D 36 square feet

Answer:

a=18

Step-by-step explanation:

The value of a or m is 18 in the linear equation, y = 5x - 2.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

The table represents a linear function.

The data is given in the attached image.

The general equation of the linear function is,

y = ax+b.

Where a is the slope and b is constant.

By using the first and the third points from the table to find the equation of the linear function,

When x = 3  and y = 13,

13 = 3a+b      {equation 1}

When x = 5 and y = 23

23 = 5a+b      {equation 2}

Solving the system of equation,

we get,  

a = 5  and b = -2

So, the equation is,

y = 5x - 2

Now, x = 4

Then y = m = 20 - 2 = 18

Therefore, the value of m is 18.

Answer:

x = 4

Step-by-step explanation:

Given

4(x + 1) - 9 = 11 ( add 9 to both sides )

4(x + 1) = 20 ( divide both sides by 4 )

x + 1 = 5 ( subtract 1 from both sides )

x = 4

Answer:

Step-by-step explanation:

4x + 4-9=11

4x  -5  =11

4x -5+5 =11+5

       4x =16

       4x divide by 4 is equal to 16 divide by 4

x is equal to 4

Step-by-step explanation:

The probability that the gumball dispensed white would be 87%.

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

It can be express the probability in either fraction form or in percentage. The numerator would be number of all possibilities, while the denominator is the number of all events.

Here the numerator is the number of white gumballs, while the denominator is the number of all gumballs available.

To solve for the number of white gumballs, subtract all the other balls to the total.

Number of white balls = 100 - 36 red - 15 blue - 24 orange - 12 green

Number of white balls = 13

Thus,

Probability of white ball = 87/100= 87%

Answer:

Step-by-step explanation:

Just replace 0 instead of x and simplify.

The required value of h(0) is 1.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Now the given function is,

h(x) = -x + 1

To find the value of h(0), put x= 0 in the given equation

⇒ h(0) = -0+ 1

Since, -0+ 1= 1

∴We obtain,

h(0) = 1

which the required value of h(0).

Hence,the required value of h(0) is 1.

Answer:

 75°C = 5h

Step-by-step explanation :

1. Make sure your mind is fresh and that you understand each step before reading

2. 24 hours is equal to  360°C

3.  so now lets break up the hours. We can do this by choosing a simple degree that was given in the diagram. For example "Watching tv".

Tip : when choosing one of the degrees , ( i mean one of the choices like watching tv, playing and sleeping) , try choosing the simplest one , which has a simple number and a multiple of 360.

so now you want to know how many hours is 60 equal to .

= 360 ÷ 60 = 60   (this is to make sure the number is a multiple and will not be a decimal )

= 24 ÷ 6 = 4

this means Ali spend 4 hours watching tv

and by doubling that you get                    60°C = 4h

the amount of time he slept                     120°C = 8h

and you keep playing with the numbers like that

so for playing                                                

                                                                   60°C = 4h

                                             divide by 4    15°C =  1h

                                           × by 5             75°C = 5h

this means ali spends 5h playing , 8h sleeping, 4h watching tv and 7 h studding

Step-by-step explanation:

−√57 is -7.54983443 repeating but rounded is -7.5 which is smack dab in the middle of integers (numbers) of -7 and -8.

The equation is given as: 13x - 4 - 74 = 0

The value of x is 6

AB = 53

BC = 21

Given,

B is between points A and C on AC.

AB = 8x + 5

BC = 5x - 9

AC = 74

We need to write an equation using the information in terms of x
We also need to find x, AB, and BC.

If there is a point between two points of a line, the sum of the two lines separated by the point is equal to the line given.

Example:

M______N____________O

Then,

MN + NC = MO

Find the equation that represents AC with point B between A and C.

We have,

A______B___________C

AB = 8x + 5

BC = 5x - 9

AC = 74

Now,

AC = AB + BC

74 = 8x + 5 + 5x - 9

74 = 13x - 4

13x - 4 - 74 = 0

Find x.

74 + 4 = 13x

78 = 13x

x = 78 / 13

x = 6

Find AB

AB = 8x + 5  

= 8x6 + 5

= 48 + 5

= 53

Find BC

BC = 5x - 9

= 5x6 - 9

= 30 - 9

= 21

Thus,

The equation is given as: 13x - 4 - 74 = 0

The value of x is 6

AB = 53

BC = 21
