bill is replacing his 15ft long by 12 ft wide deck. his new deck will add 5 feet to the length and 4 feet to the width. if a dra
Ira Lisetskai [31]

The dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.

Given that the length of the previous deck = 15 feet

The width of the previous deck = 12 feet

Since the new deck will add 5 feet to the length and 4 feet to the width,

The length of the new deck = 15 + 5 = 20 feet

The width of the new deck = 12 + 4 = 16 feet

Also given that a drawing of the new deck uses a scale of 1 inch = 2.5 feet.

So, The length of the deck in the drawing = 20/2.5 inches = 8 inches

The width of the deck in the drawing = 16/2.5 inches = 6.4 inches

Therefore, the dimensions i.e. length and width of the deck in the drawing is 8 and 6.4 inches respectively.

Omar has 3 1/14 cups of dough to make dumplings.If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar
Bumek [7]

Answer:

Omar can make 16 dumplings with some dough to spare

Step-by-step explanation:

you should convert each value to have the same denominator to make the equation easier

3 and 1/14 cups is the same as 43/14 cups of dough

so the total 43/14 needs to be divided by 3/16

43/14 divided by 3/16 = 43/14 * 16/3

=688/42 = 16.3809...

so Omar can make 16 dumplings with some dough to spare
