Answer:
Step-by-step explanation:
Consider the figure as 3 parts: semicircle with radius of 4 in, rectangle with 7x9 in and rectangle 6x14 in.
<u>Area of semicircle:</u>
- A = 1/2*πr² = 1/2*3..14*4² = 25.12 in²
<u>Area of rectangles:</u>
- 7*9 = 63 in²
- 6*14 = 84 in²
<u>Total area:</u>
- 25.12 + 63 + 84 = 172.12 in²
Answer: 56.4102564% decrease
Explanation: First determine whether the number is increasing or decreasing. Since it changes from 39 to 17, it's going down so it's decreasing.
Now to find the percent decrease,
we divide the amount of change by the original number.
The amount of change is the difference between the two numbers
which in this case is 39 - 17 and the original number is 39.
39 - 17 is 22 so we're left with 
which gives us 56.4102564
Remember however that our problem is asking for a <em>percent</em>, not a decimal. So we need to write 56.4102564 as a percent by moving the decimal point 2 places to the right to get 56.4102564.
So when a number changes from 39 to 17, it has decreased by 56.4102564%.
.32 is the answer to this question
Answer:
6^8.
This evaluates to 1,679,616.
Step-by-step explanation:
(6^4)^2
Using the law of logs (a^b)^c = a^bc:
(6^4)^2 = 6^(4*2)
= 6^8
This evaluates to 1,679,616.
Answer:
z = 62
y = 117
Step-by-step explanation:
Z
118 and z are supplementary.
z + 118 = 180 Supplementary angles add to 180. Subtract 118 from both sides.
z = 180 - 118 Do the subtraction
z = 62 Answer
Y
The interior angles of all quadrilaterals (convex) add up to 360 degrees.
y + z + 84 + 97 = 360 Given
62 + y + 84 + 97=360 Add
y + 243 = 360 Subtract 243 from both sides
y = 360 - 243 combine
y = 117 Answer
