part A. area = L X H

9 x 8/9 = 72/9 = 8 square feet

Part B. Draw a line diagonally either between Point A & C or B & D, this would make 2 triangles.

the area of the triangle would be half of the full area so 8 / 2 = 4 feet square

Mary mixes white paint and blue paint in the ratio 2:3

Sedbober [7]

Given:

Ratio of white and blue paint is 2:3

Total quantity of paint is 20 litres

To find:

Quantity of blue paint to be mixed so that the ratio of white paint to blue paint becomes 1:7

Solution:

The ratio 2:3 totals 20 that is $2x+3x=20\rightarrow5x=20\rightarrow x=4$

So, the quantity of white paint in the mixture is $2\times4=8$ and the quantity of blue paint in the mixture is $3\times4=12$

Now, to get the final ratio as 1:7, Mary should have $7\times8=56 \text{ litres }$ of blue paint. So, she need to add $56-12=44 \text{ litres}$ .

Therefore, Mary has to add 44 litres of blue paint to the mixture to make the ratio as 1:7.

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour. What was their speed in pounds per hour.

allochka39001 [22]

Team tool Bella gathered 15 pounds of wood in 1/3 of an hour.

1/3 of an hour is equal to 1/3 of 60 mins = 1/3 * 60 mins = 20 mins

We have to find their speed in pounds per hour( 60 mins).

Pounds of woods gathered in 1 hour or 60 mins = 15/20*60

= 15 * 3

= 45 pounds

Therefore, their speed in pounds per hour is 45 pounds / hour

Hope this helps ..!!

Thank you :)
