There is 100% total
20% goes into 100% 5 times
If 60 is 20%, multiply 60 by 5 to get 100%
60 x 5 = 300 min

60 times 5 is 300 minutes, The 5 is there because 20% goes into 100% 5 times

What linear function can be represented by the set of ordered pairs?

zzz [600]

Solving for the slope using points ( (−4, 15), (0, 5)
M = ( 15 – 5) / ( -4 – 0) = -5 / 2
Solving for b 
Y = mx + b 5 = 0(-5/2) + b
B = 5
So the linear function is
Y = (-5/2) x + 5

Diagonal of the parallelogram divides the parallelogram in to two equal areas.

So area of parallelogram = 2(area of triangle)

According to the given diagram,

AB= 8, AD = 5 and BD = 11

So according to the Heron's formula,

Area of triangle = $\sqrt{s(s-a)(s-b)(s-c)}\\\\where,\\ s =\frac{a + b + c }{2}$

and a, b and c are the three sides of the triangle

Area of triangle ABD = $s=\frac{8 + 5 + 11}{2} \\\\s = \frac{24}{2}\\\\s = 12Area of triangle ABD = \sqrt{12(12 - 8) (12 - 5) (12 - 11)}\\\\Area of triangle ABD = \sqrt{12(4) (7) (1)}\\\\Area of triangle ABD = \sqrt{336}\\\\Area of triangle ABD = 18.33$
