First we find how many minutes Tim walks to school.

60/12 = 5 Basically we are finding how much 1/12 is and multiplying it by 5, we can use other ways to, but this is how I do it.

5x5=25

7:35 - 0:25 = 7:05 am is the time for Getting Ready For School

3/4 = 60/4 = 45 min

7:05 - 0:45 = 6:20 am is the time Tim woke up.

Step-by-step explanation:

Answer:

y= 4/1x+3

Step-by-step explanation:

y=mx+b

first identify "b", which is where the line crosses the y-axis, in the graph we can see it does so at unit 3.

b= 3

next, we will find where the line crosses any point on the graph perfectly, such as coordinate (1, 7). Now use unit 3 on the y-axis as your reference point, we can see coordinates (1, 7) is 4 units up and 1 unit to the right from our reference point. This indicates our "m",

m= 4/1

therefore, y=4/1x+3

1 yard in 6 minutes

Question 1
Part A

Find the unit rate.

Answers

The unit rate is 1 yard :: 6 minutes. This is correct because you cannot divide each number evenly.

The unit rate in feet per second is 1/120 feet/sec.

Given that, 1 yard in 6 minutes.

What is the unit rate?

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

We know that 1 yard=3 feet and 1 minute = 60 seconds

Now, 6 minutes = 360

So, unit rate is 3/360

= 1/120 feet/sec

Therefore, the unit rate in feet per second is 1/120 feet/sec.

The perimeter cannot be same but the Equation can be 4x+ 4= 4x+ 8.

what is Perimeter?

The complete length of a shape's boundary is referred to as the perimeter in geometry. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.

Given:

For Square:

We have side= x+ 1

Now, Perimeter of Square = 4 x side

                                            = 4(x+ 1)

                                            = 4x+ 4

For Rectangle:

We have length= x+ 4 and width= x

Now, Perimeter of Square = 2 ( l+ w)

                                            = 2( x+ x+ 4)

                                            = 4x+ 8

So, the perimeter cannot be same but the Equation can be 4x+ 4= 4x+ 8.
