Numerele 10 si 5 seunt invers proportionale cu numerele 8 si b. Atunci b este:

b should be 4.

Step-by-step explanation:

Put the numbers shown in the problem (10, 5, 8) and b into an equation.

10/5 = 8/b

Multiply both sides by b

10/5b = 8

2b = 8

b = 4

b should be 4 in this case.

In Romanian:

Puneți numerele prezentate în problemă (10, 5, 8) și b într-o ecuație.

10/5 = 8 / b

Înmulțiți ambele părți cu b

10 / 5b = 8

2b = 8

b = 4

b ar trebui să fie 4 în acest caz.

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,
