Iteru [2.4K]

7 x 13 = 91 x 4 = 364 = Area of the four rectangles.

8 x 7 = 56 x 2 = 112 = Area of the two squares.

364 + 112 = 476 cm2

Surface Area = 476 cm2

What are the original dimensions of the square piece of paper?

Inga [223]

Answer:

6root2 × 6root2

you have to use pythagoras

a²+b²=c²

c=12

12²=144

a²+b²=144

but it is a square so I'll just change a and b to x because it shows they are equal

x²+x²=144

2x²=144

x²=72

x=6root2

An airplane flying at 600 miles per hour has a bearing of 53°. After flying for 2.5 hours, how far north and how far east will t

serg [7]

Answer:

Eastward distance of airplane = 903 miles

Northward distance of airplane = 1198 miles

Step-by-step explanation:

Consider the sketch attached below.

Let the Eastward distance be represented by x

let the Northward distance be represerted by y

The distance traveled = speed of plane x time

= 600 x 2.5 = 1500 miles

from basic trigonometry of a right angled triangle we have that

$sin(53)=\frac{x}{1500}$

$x=1500\timessin(53) \approx 903 miles$

$cos (53) = \frac{y}{1500}$

$y= 1500cos(53)\approx1198 miles$

∴ Northward distance = 1198 miles

Eastward distance =903 miles
