Answer:

<em>32.5 m^2</em>

Step-by-step explanation:

B = 377lw

I will use L for length instead of l.

B = 12,252.5 BTU

w = 5 m

First, we find the length.

12,252.5 = 377(L)(5)

12,252.5 = 1885L

L = 6.5

The length is 6.5 m. The width is 5 m.

A = LW = (6.5 m)(5 m) = 32.5 m^2

A local garden contains 1/12 lettuce, 3/12 carrots, 4/12 of corn and the rest red radishes. How much of the garden is radishes?
melamori03 [73]

Answer:

The answer to your question is a) 4/12    b) 5/12

Step-by-step explanation:

Data

Lettuce = 1/12

Carrots = 3/12

Corn = 4/12

Red radishes = ?

a)

The total of the garden is 12/12

Red radishes = 12/12 - 1/12 - 3/12 - 4/12

                      = 12/12 - 8/12

                      = 4/12

4/12 of the garden are red radishes.

b)

Corn of lettuce = 1/12 + 4/12

                         = 5/12

5/12 of the garden are corn or lettuce.

WITCHER [35]

maple syrup = x

corn syrup = 50-x

6x + 0.8(50-x)=2.36*50

6x+40-0.8x=118

5,2x=78

x= 15 gallons of maple syrup

50-15 = 35 gallons of corn syrup
