Answer:
82 degrees
Step-by-step explanation:
It took 3 hours for it to go from 78 to 72.
Which is a rate of -2 degrees per hour
We want to know what the temperature was two hours before it was 78 degrees so we'd do 78 - (-2) which is 82

a. What is the difference in height between 30 m up a cliff and 87 m up a cliff? What is the distance between these positions?
b. What is the difference in height between an albatross flying at 100 m above the surface of the ocean and a shark swimming 30 m below the surface? What is the distance between them if the shark is right below the albatross?
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
which expression means “ multiply 3 by the sum of m and p “
Answer:
3m+3p
Step-by-step explanation:
Sum of m and p is expressed as;
m + p (sum means addition)
If 3 is multiplied by the sum, this is expressed as;
3(m+p)
Expand
3m + 3p
Hence the required expression is 3m+3p

Bo and Dan Brady's income last year was: net income from
business, $35,838.67; dividends, $2,312.98; interest, $3,517.45;
rental income, $2,672. Adjustments to income totaled $4,628.83.
Find their adjusted gross income.
The adjusted gross income is the value of an individual's earning after deducting adjustment amount from overall gross. Hence, Bo and Dan Brady's adjusted gross income is $39,712.27
Total income earned is the sum of the following :
Net income from business = $35,838.67Dividend = $2,312.98Interest earned = $3,517.4Rental income = $2672The total amount reuzed last year :
Net income + Dividend + Interest + Rental income $(35838.67 + 2312.98 + 3517.45 + 2672) = $44341.1The adjusted gross income can be calculated thus :
Adjusted gross = Total earning - adjustment Adjusted gross income = $(44341.1 - 4628.83) = $39,712.27Therefore, the adjusted gross income of Bo and Dan Brady's income last year = $39,712.27

Use the Pythagorean Theorem, and the properties of right triangles to model an equation that fits the problem. One of the cables that anchors the center of the London Eye Ferris wheel to the ground must be replaced. The center of the Ferris wheel is 69.5 meters above the ground, and the second anchor on the ground is 23 meters from the base of the Ferris wheel. Approximately how long is the cable, and what is the angle of elevation (from ground up to the center of the Ferris wheel)
Answer:
73.21 m
71.68°
Step-by-step explanation:
Like the question has stated, we're to solve this using Pythagoras theorem.
Pythagoras theorem states that
opp² + adj² = hyp²
From the question, we're asked to find the hypotenuse, being given the opposite side and the adjacent. The opposite side is the center of the Ferris wheel above the ground, and that is 69.5 m. While the adjacent is the distance of the second anchor.
Succinctly put, we have
69.5² + 23² = hyp²
4830.25 + 529 = hyp²
hyp² = 5359.25
hyp = √5359.25
hyp = 73.21 meters.
Therefore, the length of the cable is 73.21 meters long.
To get the angle, we use the formula
Sin Φ = opp/hyp
Sin Φ = 69.5 / 73.21
Sin Φ = 0.9493
Φ = sin^-1 0.9493
Φ = 71.68°
Therefore, the angle of elevation to the center of the Ferris wheel is 71.68°
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.
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;

Does anyone know how to do this? I really need help, I don't understand.
Answer:
I'm assuming you are looking for the amount of possible outcomes
1. 10 possible outcomes
2. 15 possible outcomes
Step-by-step explanation:
When you first start solving these problems the easiest thing to do is create a diagram of sorts to list all of your possible outcomes. For the first question the coin will either land on heads or tails and the spinner will land on the numbers 1, 2, 3, 4, or 5. Therefore the possible outcomes are H1, H2, H3, H4, H5, T1, T2, T3, T4, or T5. Add them up to get 10 possible outcomes. For the second question you will either pick 1, 2, 3, 4, or 5 and the colors red, white, or blue. Listing out all the possibilities gives you 1R, 2R, 3R, 4R, 5R, 1W, 2W, 3W, 4W, 5W,1B, 2B, 3B, 4B, or 5B. Add them up to get 15 possible outcomes.
Alternatively
For the first question you flip a coin thus you have a 1/2 chance for landing on either, then you spin the wheel where you have a 1/5 chance to land on any of the numbers. Multiply these values together you have a 1/10 chance, therefore there are 10 possible outcomes.
For the second question you have a 1/5 chance for the number and a 1/3 chance for the color. Multiply to get 1/15, therefore you have 15 possible outcomes.
