Answer:
a11 = -53
Step-by-step explanation:
an = -6n +13
We want the 11th term, so n =11
a11 = -6(11) +13
= -66 +13
= -53
Answer:
45°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
60 + x + 87 + x + 57 = 180 add like terms
2x + 204 = 180 subtract 204 from both sides
2x = -24 divide both sides by 2
x = -12
angle A is x + 57 so if we replace A with the value we found
(-12) + 57 = 45°
Answer: 97
Step-by-step explanation: The first 25 prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 (sequence) just if you need all the primes
Area for circle is πr² so πr² =28.26 and we can sub 3.14 as pi
3.14*r²=28.26 we can divide by 3.14 to get r² on it's own
r²=28.26/3.14
then we root both sides to get r on it's own
28.26/3.14=9 √9=3
and the diameter is double the radius 3*2=6 so the diameter is 6
