Answer:
<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>
Step-by-step explanation:
To find the mass in kg we must first convert the density from g/cm³ to kg/m³
That's 7.5 g/cm³ = 7500kg/m³
Density = mass / volume
Volume of block = 1.5 × 0.4 × 0.25
= 0.15m³
mass = Density × volume
= 7500 × 0.15
<h3>= 1125 Kg</h3>

the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.

Answer:We are also given that Ishaan is 14 years older than Christopher, so I is also 14 more than c. This gives that I = c + 14. Since I = 3c and I = c + 14, we have that 3c is equal to c + 14, giving the equation 3c = c + 14.
well this is from google and just so u know the letters stand for the names
Answer:
45 km/h
Step-by-step explanation:
In the first part of the trip, he already covered 30 km so we can subtract that from the total distance
45 - 30 = 15
This means he has 15 km to go
He also took an hour, or 60 minutes, to get to school. We subtract the time spent of the first part and time spent talking to a friend from the 60 minutes
60 - 35 = 25
25 - 5 = 20
He took 20 minutes to cover the second part of the journey
Speed = distance/time
15/20 = 0.75
He covered 0.75 km per MINUTE
to find it in km/h, we just multiply the number by 60
0.75 x 60 = 45
