Answer:
Speed per second= 7.5 feet per second
Step-by-step explanation:
Giving the following information:
We have a distance (225 feet), and a time (30 seconds). Also, we know that the speed was constant.
All we have to do is divide the distance by the time and determine the speed per second:
Speed per second= distance / time
Speed per second= 225 / 30
Speed per second= 7.5 feet per second

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.
The rate of change increased by about __________ bass per a year.
Answer:
60 bass per year
Step-by-step explanation:
Answer:
1.2
Step-by-step explanation:
Since 3,000 bass population grows by 2% each year, multiply 3,000 by 1.02 to find next year's population. Since we're looking for a rate of change, multiply that new total by 1.02 again. The two values that you should have gotten are 3,060 (first time), and 3,121.2
But we know that the population started at 3,000. Now this is why we needed 3 values:
Take the difference between 3,060 and 3,000. Then take the difference between 3,121.2 and 3,060. 3,060-3,000=60 and 3,121.2-3,060=61.2
Now 60 and 61.2 are the rates of change for those two values. There is a 1.2 difference between them, meaning that the rates of change increase by 1.2 annually.

5. A submarine is searching for underwater features. It is accompanied by a small
At one time the aircraft is 200 m above the surface, the submarine is 55 m below
aircraft and an underwater robotic vehicle,
the surface, and the underwater robotic vehicle is 227 m below the surface
What is the difference in height between the submarine and the aircraft?
1.
2. What is the distance between the underwater robotic vehicle and the
submarine?
Answer: The required difference is 255 m .
Step-by-step explanation: Since we have given that
Distance at which the aircraft is above the surface = 200 m
Distance at which the submarine is below the surface = 55 m
Above the surface is represented as positive number i.e. (+) 200 m
Below the surface is represented as negative number i.e. (-) 55 m
Hence, the required difference is 255 m .

Michelle records the value of one Euro in U.S. dollars each day for her social studies project. On Monday the value was 1.448, Tuesday it was 1.443, Wednesday it was 1.452, and Thursday it was 1.458. On which two days was the value of 1 euro the same when rounded to the nearest hundredth of a dollar?
Answer:
It is Monday and Wednesday
Step-by-step explanation:
Round all of the digits to the nearest hundredth.
1.448 = 1.450
1.443 = 1.440
1.452 = 1.450
1.458 = 1.460
Two of them are the same which is Monday and Wednesday.

Write the equation of the line that passes through the points (-3,-8) and (6,-4).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
The equation in point-slope form is: [tex]\mathbf{y+8= \frac{4}{9}(x+3)}[/tex]
Step-by-step explanation:
Write the equation of the line that passes through the points (-3,-8) and (6,-4)
The point slope form is: [tex]y-y_1=m(x-x_1)[/tex]
Where m is slope and x₁ and y₁ are the points given
Finding Slope
Slope can be found of given points using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=-3, y_1=-8, x_2=6 \ and \ y_2=-4[/tex]
Putting values and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-4-(-8)}{6-(-3)}\\Slope=\frac{-4+8}{6+3}\\Slope=\frac{4}{9}[/tex]
So, slope m = 4/9
Using point (-3,-8) and slope m = 4/9 the equation is:
[tex]y-y_1=m(x-x_1)\\y-(-8)=\frac{4}{9}(x-(-3))\\y+8= \frac{4}{9}(x+3)\\[/tex]
So, the equation in point-slope form is: [tex]\mathbf{y+8= \frac{4}{9}(x+3)}[/tex]

If a triangle has a 30° angle and a 60° angle, then the triangle is an obtuse triangle
True or false
Answer:
False
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
60+30=90, and because a triangle always has a total of 180 degrees for their interior angles, the remaining angle is 90 degrees, so it is a right triangle, not obtuse.
Find the common difference of the following sequence.
You have the correct answer. It is choice B) -1/4
=======================================================
Explanation:
This is because we're adding -1/4 to each term to get the next one. In other words, we're subtracting 1/4 from each term to get the next one.
term2 = term1+(d) = 1/2 + (-1/4) = 1/2 - 1/4 = 2/4 - 1/4 = 1/4term3 = term2+(d) = 1/4 + (-1/4) = 1/4 - 1/4 = 0term4 = term3+(d) = 0 + (-1/4) = 0 - 1/4 = -1/4term5 = term4+(d) = -1/4 + (-1/4) = -2/4 = -1/2and so on.
----------
To find the common difference, all we have to do is subtract any term from its previous one.
For example:
d = (term2) - (term1)
d = (1/4) - (1/2)
d = (1/4) - (2/4)
d = (1-2)/4
d = -1/4
The order of subtraction matters, so we cannot say d = term1-term2.

At Westside Middle School, 10 percent, or 140 students, participate in soccer. How many students are in the school? Check all that apply.
The total number of students is greater than 140.
The total number of students is less than 140.
(10)(14) = 140, so 100(14) = 1,400 students.
140 + 10 = 150, so 150 + 140 = 290 students.
There are 140 + 10 = 150 students at Westside Middle School.
The percent as a part to whole ratio is StartFraction 140 Over 100 EndFraction
The percent as a part to whole ratio is StartFraction 10 Over 100 EndFraction
Answer:
A: The total number of students is greater than 140.
C: (10)(14) = 140, so 100(14) = 1,400 students.
F: The percent as a part to whole ratio is 140 Over 100
