So the answer will be like
Let the time taken be x
4:120::x:80
120x= 80*4
x = 80*4/120
x=8/3
x= 2 2/3

QUICKLY!!!<br> I need the answer to this, please
Yuri [45]

8/(1/6) = (8/1)/(1/6) = (8/1) * (6/1) = 48/1 = 48

Patel found the quotient incorrectly since he got 1/48.

To check the division, he needed to multiply 48 by 1/6 and get 8.

Instead, he multiplied 1/48 by 6, so the multiplication done as a check is also incorrect.

Answer: last choice

(0 , -1)

Step-by-step explanation:

WR = 4 + 2 = 6

WS = 1/3 x WR = 2   .... the point of 1:2 of WR

S (-2 + 2 , -4) i.e. (0,4)

The same reason: RQ = 1/3 x RY = 1/3 x (5 + 4) = 3

Q (-4 , -4 + 3) i.e. (-4, -1)

The length of a rectangle is 12 cm more than its width. Find the
just olya [345]

Dimensions of the rectangle (width and length) are 19 cm and 31 cm respectively.

Step-by-step explanation:

  • Step 1: Given that the perimeter = 100 cm, let width be x cm and then length = 12 + x.

Perimeter of a rectangle = 2(length + width)

100 = 2(x + 12 + x)

100 = 4x + 24

4x = 100 - 24 = 76

∴ x = 76/4 = 19 cm

∴ Length = 19 + 12 = 31 cm
