Unit test, Part 2: Measurement of Two-Dimensional Figures Please help!!!

Mathematics
1 answer:
Vitek1552 [10]3 years ago
4 0

Answer:

Step-by-step explanation:

1. Area of the composite figure = Area of the sector + Area of rectangle

Area of sector = (θ/ 360) x \pir^{2}

From the figure,

θ = 30, and r = 65

Area of sector = \frac{30}{360} x \frac{22}{7} x 65 x 65

                        = 1 1065.55m^{2}

Area of rectangle = length x width

                        = 65 x 4

                       = 260 m^{2}

Area of the composite figure = 1 1065.55 + 260

                                                  = 11325.55

Area of the composite figure is 11326 m^{2}.

One number is 6 more than twice another. If their sum is 51, find the numbers.
joja [24]

Answer:

y=2x+6 ; x+y=51

Step-by-step explanation:

assuming x is one number and y is the other -

one number (y) is 6 more (+6) than twice another (2x) -

using that knowledge we form an equation -

y=2x+6

the sum (x+y) is 51

using this knowledge we can make the equation -

x+y=51

now you have -

y=2x+6 or 2x-y=-6

x+y=51

using system of equations -

you add the equations -

3x=45

x=15

y=51-x => y=36

hope this helps!!
