Answer:
B, but I can't read C
Step-by-step explanation:
the sum of any 2 sides must be longer that the 3rd.
A is not correct, 2 + 15=17, needs to be greater.
B 1, 8, 8.1 so yes as 1+8 >8.1
C 2, 8.9, I cna't tell if that last number is 9 or 92?
This is how I would work it out:
1st no. = x+1 2x+10=3(x+1)-7
2nd no. = x 2x+10=3x-4
x=14
1st no. is 15; 2nd no. is 14
To check: 28+10=38; three times the larger is 45; and 38 is 7 less than 45.
Answer:
Step-by-step explanation:
The purple circle, not ring is pi 7 squared = 153.93804
Then subtract the smaller circles area (pi 4 squared) = 153.9... - 103.6725576 =
50.2654824
Purple ring is 50.2654824
The entire circle is 4+3+3 (10) squared times pi = 314.1592654
( 50.2654824 / 314.1592654 ) x 100 = 15.999999998 %
36/7+4
36/11
36÷11=3.27272727.... Repeating
