Step-by-step explanation:
-12x < -12
-12x/-12= x
-12/-12= 1
x < 1
It’s c
You would use cah which is cosine
20 x cos(30
Answer:
2 of these numbers are divisible by 4 and 5.
20 and 60 are divisible by 4 and 5.
Step-by-step explanation:
20 is divisible by 4 and 5.
Divisible just means that the 4 (also the 5) goes into 20 evenly, with no remainder.
4 goes into 20 evenly with no remainder.
5 goes into 20 evenly with no remainder.
4 does not go into 35 evenly with no remainder.
35 ÷ 4 is 8 with a remainder of 3.
35 ÷ 4 = 8.75
5 does go into 35. 35 is divisible by 5.
35 is not divisible by 4.
60 is divisible by 4
60 ÷ 4 = 15 (no remainder, no extra decimals if you do it on a calculator)
60 ÷ 5 = 12 (no remainder, no extra decimals if you do it on a calculator)
60 is divisible by 4 and also by 5.
I’ve attached a sketch of what it would look like
This is the sum of the arithmetic sequence:
10 - 2 + 6 + 14 + ... + 110
where: a 1 = - 10, d = 8
a n = 110
a n = a 1 + ( n - 1 ) * d
110 = - 10 + ( n - 1 ) * 8
110 = - 10 + 8 n - 8
110 + 10 + 8 = 8 n
128 = 8 n
n = 128 : 8
n = 16
∑ n = n/2 * ( a 1 + a n )
∑ 16 = 16/2 * ( -10 + 110 ) = 8 * 100 = 800
Answer:
The sum is 800.
