40% of what number is 30?

Answers

30 = 40% * x

30 = 40/100 * x

30 = 4/10 * x

30 = 2/5 * x

x = 30 * 5/2

x = 15 * 5

x = 75

40% of 75 is 30

The length of a rectangle is (2x+5) units and the breadth is (3x-1) units .Find the perimeter and the area of the rectangle.

Answers

Answer:

Perimeter = 10x + 8 units.

Area = 6x^2 + 13x - 5 units^2.

Step-by-step explanation:

The perimeter is 2*length + 2*breadth

= 2(2x + 5) + 2(3x - 1)

= 4x + 10 + 6x - 2

= 10x + 8 units.

The area = length * breadth

= (2x + 5)(3x - 1)

= 6x^2 - 2x + 15x - 5

= 6x^2 + 13x - 5 units^2.

If someone eats 3 sundaes in 9 minutes what portion of a sundae can they eat in one minute

Answers

Answer:

Number of sundaes eaten per minute = 3 sundaes

Step-by-step explanation:

Number of sundaes eaten in 3 minutes = 9 Sundaes

So, by UNITARY METHOD:

Number of sundaes eaten in 1 minute = $\frac{\textrm{Sundaes eaten in 9 minutes}}{\textrm{3 minutes}}$

= $(9 )/(3 ) = 3$

So, number of sundaes eaten per minute = 3.
