A) using prime factorization (dividing with a prime factor until everything is a prime number, then multiplying the prime numbers by each other once), u can calculate their lcm
122=2x61
15=5x3
834=2x3x139
then multiply the prime factors once,
2x3x5x61x139= 254,370
b) i’m assuming that u solve the equation first bc u didnt put any commas
42-12-16=14
3-92+20=-69
do prime factorization
14=2x7
-69=-23x3
multiply the factors
-23x7x3x2=-966

Step-by-step explanation:
Apex
The term in the expansion:
T ( k+1) = n C k * A^(n-k) * B^k.
In this case: n = 11, k + 1 = 8, so k = 7.
A = x, B = - 3 y
T 8 = 11 C 7 * x^(11-7) * ( - 3 y )^7 =
=( 11 *10 * 9 * 8 * 7 * 6 * 5 ) / ( 7 * 6 * 5 * 4 * 3 * 2 * 1 )* x^4 * ( - 2,187 y^7 ) =
= 330 * ( - 2,187 ) x^4 y^7 = - 721,710 x^4 y^7
Answer: The 8th term in expansion is
Answer:
0.5
Step-by-step explanation:
Total space in the parking lot = 10
number of cars parked = p
number of empty parking spaces = e
There are the same number of cars parked in the parking lot as there are empty parking spaces.
This means,
Number of parked cars = number of empty parking spaces
p = e
If the number of parked cars and number of empty parking spaces = 10
p + e = 10
If p = 5
Then,
p + e = 10
5 + 5 = 10
Write a decimal to show the part of the parking lot that has empty parking spaces.
Empty parking space/total parking space
= 5/10
= 1/2
= 0.5
part of the parking lot that has empty parking spaces = 0.5
