Calculating Rate of change
ivolga24 [154]

Answer/Step-by-step explanation:

We are given the following coordinates of two points on the line of the graph shown in the question as: A(2, 1) and B(4, 2)

Vertical change from point A = y_2 - y_1 = 2 - 1 = 1

Horizontal change from point A = x_2 - x_1 = 4 - 2 = 2

Rate of change = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1}{2} = 0.5

Find the number, if 3 1/3 of it is 10
Ugo [173]

Answer:

3

Step-by-step explanation:

You want a number that if it is multiplied by 3 1/3 the result will be 10. Let the number be x

3 1/3 * x = 10                         Change to a mixed number

10/3 * x = 10                          Multiply by 3/10

(10/3)*x * 3/10 = 10 * 3/10     Combine

x = 10*3 / 10                          Simplify

x = 30/10 = 3

Dmitry_Shevchenko [17]

Answer:

the price paid is  £288,000

Step-by-step explanation:

The computation of the price paid is shown below:

Sale of the another house is £283,392

Since the another house would be 1.6% less than the price paid

So, the price paid would be

=  £283,392 × 100 ÷ (100 - 1.6%)

=  £283,392 × 100 ÷ 98.4

=  £288,000

Hence, the price paid is  £288,000
