The area of the big circle is 415.48 and the smaller one is 59.69 so divide 59.69 by that number and multiply by 100 then do 100- that number(14.37) to get 85.63%
The answer is Y=16 I know because I did it
The answer to the question
Answer/Step-by-step explanation:
In mathematics, there's an order to follow in solving calculations like the problems given above. The acronym, PEDMAS illustrates or makes us remember which order to follow. The acronym stands for:
P - Parenthesis. Given any problem to solve, first, solve any operation within a parenthesis. That is, expressions that are grouped together.
E - Exponents. Next in line of priority order is to solve expressions involving exponents.
D - Division
M - Multiplication
A - Addition, and
S - Subtraction.
Now, solve each expression given in the correct order of operation using PEDMAS:
10 - 3³ ÷ 9
10 - 27 ÷ 9
10 - 3
= 7 (the order of operation is EDS = Exponent, Division, and lastly, Subtraction)
7² ÷ (4 + 3)
7² ÷ 7
49 ÷ 7
= 7 (order of operation = PED)
7 × 5 - 2²
7 × 5 - 4
35 - 4
= 31 (EMS)
(6 + 2²) × 10
(6 + 4) × 10
10 × 10
= 100 (PM)
3 × 6 + 8²
3 × 6 + 64
18 + 64
= 82 (EMA)
4³ - 10 ÷ 5
64 - 10 ÷ 5
64 - 2
= 32 (EDS)
3² × 2 - 9
9 × 2 - 9
18 - 9
= 9 (EMS)
9 × 3² - 8
9 × 9 - 8
81 - 8
= 73 (EMS)
6² ÷ 3 - 5
36 ÷ 3 - 5
12 - 5
= 7 (EDS)
(9 - 5)² ÷ 4
(4)² ÷ 4
16 ÷ 4
= 4 (PED)
Answer:
X=27
Step-by-step explanation:
90+36=126
180-126=54
54/2=27
The line is strait therefore it is 180 degrees and the right angle is 90 plus the 36 angle equals 126. Then you take that away from 180 to find how much the other angle is. After you find that it is 54 you divide it by 2 because it is 2x.
