Answer: 9 cm.
Step-by-step explanation:
You are given that increase in snow level are recorded with positive numbers while it is recorded with negative number when it is decreasing.
The initial depth of the snow is 10 cm
The rate = 1/3 cm/h
Time t = 3 hours
Using the formula
Rate = depth / time
Substitute the rate and the time into the formula
1/3 = depth/3
Cross multiply
Depth = 3 × 1/3
Depth = 1 cm
The depth of the snow on Cherry street after 3 hours will be
10cm - 1 cm = 9 cm.
Answer:
b. Determine the number of homozygous dominant alleles for red eyes
Step-by-step explanation:
Because, well, without them how are you able to add and subtract fractions :D
It is according to the laws of mathematics that you cannot add or subtract fractions that have different denominators to each other. So you need to make your fractions having the same denominator so that they are able to be added or subtracted (hence the equivalent fractions - making the denominators the same are making the fractions equivalent)
Answer:
Here we will use the relation:
Density = mass/volume.
We know that:
Mass = 1485g
Volume = 750L
Density = 1485g/750L = 1.98 g/L
We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.
Two "common" gases with densities similar to this one are:
Carbon Dioxide, with d = 1.977 g/L
Dinitrogen Monoxide, with d = 1.977 g/L
In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
