Hello,
10*10=100>89
n=89 is prime if it not divisible by all prime less then its square root
0<89<100 ==>0<√89<10
The primes to test are 2,3,5,7.
89 does not end with a even digit ==> 89 is not divisible by 2
8+9=17 if not divisible by 3 ==>89 is not divisible by 3
89 does not end with 0 or 5 ==>89 is not divisible by 5
3*8+1*9=33 is not divisible by 7 ==>89 is not divisible by 7
So: 89 is prime.
Answer:
100 yd^3
Step-by-step explanation:
The formula vor value of prisma is
V=abc, where a=10, b=2 and c=5
V=10*2*5=100 yd^3
The answer is 13.25
67+92= 159
159 divided by 12= 13.25
K = 
(F - 32) + 273.15
To cancel out the 5/9, you can either multiply everything by the denominator and divide it down, or multiply everything by the reciprocal of the fraction (
. Multiplying by the reciprocal is definitely easier if you can use a calculator:
K = (F - 32) + 491.67
Subtract 491.67 from both sides:
K - 491.67 = F - 32
Finish off by adding 32 to both sides:
K - 459.67 = F
Therefore, F = K - 459.67.
Hope this helps! :)
Answer:
The slope is -4
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
(1-5)/(3-2)
-4/1
