Answer:
4 2/3 ÷ 3 1/3= 1 2/5
Step-by-step explanation:
First, you turn the mixed terms into an improper fraction like this
4 2/3 → 14/3 because when you multiply 4 times 3 equaling 12 then having 2 then adding that you get 14/3.
3 1/3 → 10/3 because when you multiply 3*3=9 then having 1 and adding that you get 10/3.
Then, you do KCF which stands for Keep Change Flip so for this you would do: 14/3 ÷ 10/3 → 14/3 × 3/10
14 × 3 = 42 and 3 × 10= 30
Now being 42/30 this is considered an improper fraction in which you have to transform it into a mixed number like this:
(For this you need to find the greatest common factor)
42/30 → 42 and 30 greatest common factor is 6 because they are divisible and factor of 6.
Now you divide both the denominator and the numerator y 6 like this:
42 ÷ 6= 7
30 ÷ 6= 5
Now we have 7/5, this is still an improper number so we see how many times 7 can go to 5 which is once. So we have 1 as whole number, now we put the reminder as the numenator of the mix fraction keeping 5 as being the denominator.
Overall, We have our answer 1 2/5
I hope this helps :D

the volume of cuboid whose sides is 8cm
Answers
Answer:
Volume of cuboid = length × breadth × height. Here, length = 14 cm, breadth = 12 cm and height = 8 cm. Volume of cuboid = 14 × 12 × 8 cubic cm. = 1344 cubic cm.
Step-by-step explanation:
V = s ^3
We can also write this as
V = s * s * s
Since s = 8, we can plug it in
V = 8*8*8
V = 64*8
V = 512

A student performed an experiment to determine the effect of acid rain on plant growth. The student divided 80 seeds of a fast-growing plant species into four groups of 20 seeds each. The four groups of seeds were then planted in soil. After all of the seeds germinated in the same growing conditions, they were watered once a day with simulated rainwater that had different levels of acidity. The acidity of the four different watering solutions was as follows:
neutral water, 0.1%, 1.0%, and 10%. The average height of the plants in each group was measured over a two-week period.
Complete the following items using the information above
a. Identify the independent variable in the experiment.
b. Describe the control in the experiment.
c. Based on the described experiment, state a valid hypothesis for the experiment.
d. The experiment was repeated and each soil had the addition of crushed limestone. Describe how the modification of the study would affect the results.
Answers
Answer:
a) The independent variable is the variable which is being taken as the source of an observation. It is the variable which is unaffected (changed) by other factors in the experiment
Here the independent variable is the acidity (concentrations) of the watering solutions
b, The control in the experiment is the plant group which are not administered the treatment of the experiment, such that they are kept the same through out to aid in validation of the correlation between the dependent and the independent variables
The control in the experiment are the group of 20 plants that received neutral water
c. A valid hypothesis is that there is no difference in the level of growth of a plant grown in acid rain and one grown with natural water
d. Limestone is composed of calcium carbonate, which is an alkaline that dissolves in water to form a basic solution that neutralizes the effect of the added acid such that it will invalidate the correlation of the level of plant growth with exposure to acid rain
Step-by-step explanation:
Acid rain is the rain in which any form of the participation having acidity components are mixed.
The acidity of the solution is the independent variable for the given experiment.Seeds groups are the control in the experiment.The difference between the growth of the height of plants with different rain water solution with neutral water is the hypothesis for the experiment.With addition of crushed limestone will disprove the experiment.Given Information-
The student divided 80 seeds of a fast-growing plant species into four groups of 20 seeds each.
Total number of groups of seeds planted in soil again are 4.
Acid rainAcid rain is the rain in which any form of the participation having acidity components are mixed.
a) Independent variable in the experiment- Independent variable is the cause of the experiment. The acidity of the plants is changed with other variables. Thus the acidity of the solution is the independent variable for the given experiment.b) Control in the experiment- An element that changes that remains unchanged by other variables is the control of the experiment. For the given problem the seeds group are not going to change and thus the seeds groups are the control in the experiment.c) Hypothesis for the experiment-Hypothesis gives a idea about what going to be happen in the experiment for the provided condition. How much difference between the growth of the height of plants with different rain water solution with neutral water is the hypothesis for the experiment.d) Effect of addition of crushed limestone- The limestone is used to neutralized the acid solution. With addition of crushed limestone will disprove the experiment.Hence,
The acidity of the solution is the independent variable for the given experiment.Seeds groups are the control in the experiment.The difference between the growth of the height of plants with different rain water solution with neutral water is the hypothesis for the experiment.With addition of crushed limestone will disprove the experiment.Learn more about the acid rain here;

Answer:
So the surface area consists of 2 triangles and 3 different rectangles
Triangle area = 1/2 * 8cm * 6cm = 24cm²
Rectangle a area (bottom one) = 17cm * 8cm = 136cm²
Rectangle b area (the one to the left) = 17cm * 6cm = 102cm²
To calculate Rectangle c we need to know the hypotenuse of our triangles
Formula for the hypotenuse is c = [tex]\sqrt{a^2+b^2}[/tex]
so c = [tex]\sqrt{6^2+8^2}[/tex] = 10
Rectangle c area = 17cm * 10cm = 170cm²
So the surface area is 2 * 24cm² + 136cm² + 102cm² + 170cm² = 456cm²
The volume is 1/2 * h * a * b = 1/2 * 6cm * 8cm * 17cm = 408cm³

Answers
Answer:
A. 57m B. 130m
Step-by-step explanation:
For problem A:
87m up a cliff - 30m up a cliff = 57m up a cliff
These are all positive values
For problem B:
100m above is talking about a positive value, making this a positive number
30m below is talking about a negative value, making this number -30
0 meters represents the surface
As you can see, this is forming a number line as of which
below the surface------------------------0m-------------------------above the surface
by substitution,
-30-----------------------------------------------0-------------------------------100
therefore, 100 - -30 = 130 meters

Nina took an exam. When her results came, she had 40% correct and 68% incorrect. Find the percent to correct answers to incorrect answers.
Answers
Answer: She had 27.2% correct.
Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,
[tex]\frac{part}{whole}=quotient*100[/tex]
40% will be the part and 68% will be the whole.
Step 1.
Convert 40 into a decimal by dividing it by 100.
40 ÷ 100 = 0.4
Step 2.
Multiply 0.4 by 68.
0.4 × 68 = 27.2
Hence, she had 27.2% correct.
