Answer:
78
Step-by-step explanation:
You know that each minute represents 6 degrees of a difference because there are 360 degrees total and 60 minutes, so 360/60 = 6 degrees.
13 minutes passed, so 13 * 6 = 78 degrees
A = LW
A = 66
L = 2W + 1
66 = W(2W + 1)
66 = 2W^2 + W
2W^2 + W - 66 = 0
(2W - 11)(W + 6) = 0
2W - 11 = 0
2W = 11
W = 11/2
W = 5.5
W + 6 = 0
W = -6 (this is an extraneous solution...it will not work)
L = 2W + 1 = 2(5.5) + 1 = 12
so ur dimensions are : Length = 12m and width = 5.5m
Answer:
1/4
Step-by-step explanation:
p% = p/100 so that
25/100 then after we will reduce both with 25
1/4
Normally, you would just use a calculator and enter √80. But if you don't want to use a calculator, remember that the square root is the number that goes into something when multiplied by itself. For example, √9 is 3, because 3*3=9. So, 80 is very close to 81. √81=9. Therefore, the answer to √80 will be slightly smaller than and extremely close to 9. Therefore, the answer is B) 8.9
