Answer:

<h3>\boxed{ \frac{11}{40} }</h3>

Step-by-step explanation:

( \frac{2}{3}  \times  \frac{3}{5} ) - ( \frac{3}{4}  \times  \frac{1}{6} )

Reduce the numbers with Greatest common factor 3

⇒\mathsf{(2 \times  \frac{1}{5} ) - ( \frac{1}{4}  \times  \frac{1}{2} )}

Calculate the product

⇒\mathsf{( \frac{2}{5} )- ( \frac{1}{4}  \times  \frac{1}{2}) }

Subtract the fractions

⇒\mathsf{ \frac{2 \times 8 - 1 \times 5}{40} }

⇒\mathsf{ \frac{16 - 5}{40} }

⇒\mathsf{ \frac{11}{40} }

Hope I helped!

Best regards!

Work out the gradient of the line joining the points (2, 3) and (5,7)
Debora [2.8K]

Answer:

The gradient of the line joining the points P(x,y) = (2,3) and Q(x,y) = (5,7) is \frac{4}{3}.

Step-by-step explanation:

The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line (m_{PQ}), that is:

m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}} (1)

If we know that P(x,y) = (2,3) and Q(x,y) = (5,7), then the gradient of the line is:

m_{PQ} = \frac{7-3}{5-2}

m_{PQ} = \frac{4}{3}

The gradient of the line joining the points P(x,y) = (2,3) and Q(x,y) = (5,7) is \frac{4}{3}.

Sales of 10000 increased by 65% each year write a function that represents the situation
erastovalidia [21]

Answer: y=10000(1.65)^x


Step-by-step explanation:

Given: The sales of 10000 increased by 65% each year .

Let x be the number of years.

The rate of growth=65%= 0.65

The exponential growth function is given by

y=A(1+r)^x

, where A is initial amount and r is the rate of growth in decimal.

Then the increase in the sales id given by :-

y=10000(1+0.65)^x\\\Rightarrow\ y=10000(1.65)^x
