U mutiply the two mumber then then divide by 2
Answer:
Step-by-step explanation:
Respectively we will say the book has One thousand pages (1000) . Now we find 1/4 of a 1000 which is 250 , then we find 1/5 of a 1000 which is 200. Now we add them together which is 250+200=450 . 450 / 1000 = 9/20 which is about a half
Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
Answer:
LCM :
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
Meanwhile
4 x 1 = 4
4 x 2 = 8
4 x 3 = 12
4 x 4 = 16
4 x 5 = 20
4 x 6 = 24
The LCM of 6 and 4 is 12
HCF:
36 : 1,2,3,4,6,9,12,36
24 : 1,2,3,4,6,8,12,24
HCF of 36 and 24 is 12
So therefore Hussein is correct because both the LCM and HCF is 12
Answer:
V = x³ + 3x² + 3x + 1 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side ) , then
V = (x + 1)³
= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL
= (x + 1)(x² + 2x + 1) ← distribute
= x³ + 2x² + x + x² + 2x + 1 ← collect like terms
= x³ + 3x² + 3x + 1
