How do you solve a unite rate

Mathematics

Answer:

To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.

Step-by-step explanation:

As an example, in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the unit rate.

Answer:

Depending on whether you are solving a unit rate from a graph or without a graph, you can the unit rate by dividing the y coordinates by the x coordinates. If you are looking for a simpler answer, then you simply divide whatever independant value by its dependent counterpart. For example, if you are looking for the price per object, then you would divide the price by the object! Lets say for a bundle of 10 toilet rolls it costs $11.55. You would divide 11.55/10 and get a unit price of $1.15 cents rounded to the hundredth decimal. I hope this helps! :)

Answer:

123°

Step-by-step explanation:

2z +9 = x

y = z

2Z +9 + X + z +Y = 360

Substitute for Z

2Z +9 + 2z +9 + z + z = 360

6z +18 = 360

6Z = 342

Z = 57

2(57) +9 = 123

X = 123

If the size of the matrix B is 4 × 5, the size of the matrix D is 4 × 2 and the order of the matrix E is 5 × 4, then the order o
kvasek [131]

Answer:

The order of the matrix D^T × (BE) is 2 × 4

Step-by-step explanation:

In the multiplication of matrix, the number of columns in the first matrix must be equal to the number of rows of the second matrix. The resulting matrix from the product will have the same number of rows as the first matrix and the same number of column as the second matrix. For example, given Matrix A of order (m × n) and Matrix Z of order ( n × k), the product of the two matrices will give a matrix ( say Y) of order (m × k).

AZ = Y

(m x n)(n x k) = (m x k)

Now, From the question,

The order of Matrix B is 4 × 5,

the order of the matrix D is 4 × 2

and the order of the matrix E is 5 × 4.

To determine the order of the matrix D^T × (BE)

First, will find the order of (BE)

Order of BE = (4 × 5) (5 × 4)

Order of BE = (4 × 4)

Hence, the order of matrix (BE) is 4 × 4.

Now, we will determine the order of matrix D^T

D^T means the transpose of matrix D.

The transpose of a matrix is defined as a new matrix whose rows are the columns of the original matrix and the columns of the new matrix are the rows of the original matrix. This means given Matrix A of order (m × n), the transpose of Matrix A (A^T) will have an order of (n × m).

The order of the matrix D is 4 × 2

Hence, the order of the transpose of matrix D (D^T) will be 2 × 4

Now, the order of the matrix D^T × (BE) will be

Order of the matrix D^T × (BE) = (2 × 4) × (4 × 4)

Order of the matrix D^T × (BE) = 2 × 4

Hence, the order of the matrix D^T × (BE) is 2 × 4.

A person sold an article at a profit of 15% , if he sold it for rs.81 less , his loss would have been 12% , find the cost price
Pepsi [2]

Answer:

cp is RS 300

Step-by-step explanation:

let cp be x

sp= 115x/100 ---(when 15%gain)

sp = 88x/100------(when 12% loss

according to question

115x/100 - 88x/100 = 81

or, (115x-88x)= 8100

or, 27x = 8100

or, x= 8100/27

x = 300

hence cp is RS 300
