(2a, b )

Step-by-step explanation:

Given the endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{1}{2}$ (x₁ + x₂ ), $\frac{1}{2}$ (y₁ + y₂ ) ]

Here (x₁, y₁ ) = N(2a, 2b) and (x₂, y₂ ) = P(2a, 0), thus

midpoint = [ $\frac{1}{2}$ (2a + 2a), $\frac{1}{2}$ (2b + 0 ) ] = (2a, b )

Step-by-step explanation:

Given: In a bowl of fruit, there are green grapes and black grapes in the ratio of 3:4 in there are green grapes.

To Find: how many black grapes are there.

Solution:

The ratio of green grapes and black grapes is 3:4

Let the number of green grapes in bowl be $=3\text{x}$

Therefore

Number of black grapes are $=4\text{x}$

now,

Number of green grapes are =24

$3\text{x}=24$

$\text{x}=8$

Number of black grapes are $=4\text{x}$

$4\times8$

hence the total number of black grapes in bowl of fruit is .
