Answer:

540 mins | 9 hours | 540, 9

420 mins | 7 hours | 420, 7

300 mins | 5 hours | 300, 5

180 mins | 3 hours | 180, 3

Step-by-step explanation:

1 hour = 60 mins

To convert hours into minutes, multiply the number of hours by 60 minutes:

9 hours × 60 mins = 540 mins

7 hours × 60 mins = 420 mins

5 hours × 60 mins = 300 mins

3 hours × 60 mins = 180 mins

Height is 2ft. More than its width. If the total area is 99ft squared , determine the dimensions of the painting.

lesantik [10]

Answer: $9\times 11\ ft^2$

Step-by-step explanation:

Given

Height is $2\ ft$ more than its width

Suppose the width is $x$ . So, height becomes $x+2$

Area of the painting is $99\ ft^2$

Area is the product of width and height

$\therefore 99=x(x+2)\\\Rightarrow 99=x^2+2x\\\Rightarrow x^2+2x-99=0\\\Rightarrow x^2+11x-9x-99=0\\\Rightarrow (x+11)(x-9)=0\\\Rightarrow x=-11,9$

Neglect the negative values

$\text{Width =}9\ ft\\\text{height =}9+2=11\ ft$
