spin [16.1K]2 years ago
7 0
Final answer = 558
Explanation
Area of rectangle = L x B
Area of triangle = 1/2(b x h)
Area of rectangle = 28 x 21 =588
Area of triangle = 1/2(base x height)
base =(21-16) = 5
height =(28-16) = 12
Area of triangle = 1/2 x 5 x 12 = 30
Area of shaded portion = 588 - 30 =558

Hope it helps

A plane left 30 minutes late than its schedule time and in order to reach the destination 1500 km away in time it had to increas
schepotkina [342]
Let x= the usual speed
1500/x would equal how long it usually took the plane to read the destination
1500/(x+100) would equal how long it would take the plane now
So\frac{1500}{x} - \frac{1500}{x+100} =  \frac{1}{2} because it would lose 30 minutes already
Simplify:
\frac{1500(x+100)-1500x}{x(x+100)} =  \frac{1}{2}
\frac{1500x+150000-1500x}{x^2+100x} = \frac{1}{2}
\frac{150000}{x^2+100x} = \frac{1}{2}
\frac{300000}{x^2+100x} =1
300000= x^{2} +100x

x^2+100x-300000=0

x^2+600x-500x-300000=0

x(x+600)-500(x+600)

(x-500)(x+600)

x=500, x \neq -600


The usual speed was 500 hm/hr

Consider a cylinder with radius 4 cm and a height of 12 cm. Describe how to calculate the volume of the given cylinder and what
Talja [164]

\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=\stackrel{cm}{4}\\ h=\stackrel{cm}{12} \end{cases}\implies V=\pi (4)^2(12)\implies V=192\pi~cm^3


192π is about 603.19 cm³.


well, it means if you grab a hmmmm cube, say that is 1cm x 1cm x 1cm, namely a 1cm tall, 1cm wide and 1cm long, whose value is 1cm³, you can fit 603.19 of those in that cylinder.
