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}.

the annual interest rate for jacks savings account increased from 2.8% to 4.1%. Describe the change as a relative change in term
densk [106]

Answer:

<u>The additional 1.3% of increase in the annual interest rate that Jack is receiving in his savings account, from 2.8% to 4.1%, represent an increase of 46.42%.</u>

Step-by-step explanation:

Jacks's savings account annual interest rate before = 2.8%

Jacks's savings account annual interest rate after the increase = 4.1%

Difference of the two rates = 4.1% - 2.8% = 1.3%

How much percentage is that additional 1.3% from the rate before the increase?

(1.3 * 100)/ 2.8 = 130/2.8 = 46.42%

<u>The annual interest rate increased by 46.42% from the previous annual interest rate.</u>
