The ratio of 4 to 8 simplifies to 1:2. X will therefore be 3/2, as 3/2:3 simplifies to 1/2 (3 = 6/2).
I think it’s the second one sorry if I’m wrong ahhh
Answer:
the first part is correct but the second should be "alternate interior angles"
Step-by-step explanation:
Answer:
added cement = 200 kg
Step-by-step explanation:
Sand = 0.8*1400
Sand = 1120 kg
If 1120 kg of sand represents the total sand in the 8:2 mixture.
We have to create the equation of the 7:3 mixture as follows.
The sand amount continues the same but the total amount of the mixture and cement will change.
0.7*mixture_mass + 0.3*mixture_mass = mixture_mass
By replacing values, we have:
1120 kg + 0.3*(1400 kg + added cement)= 1400 kg + added cement
added cement = 200kg
Answer:
72
Step-by-step explanation:
Find the LCM
6=2x3
8=2x2x2
9=3x3
12=2x2x3
LCM=2³x3²
=72
