A scientist looks at a cell through a microscope. The actual diameter of the cell is 2.5 x 10*-5 meters. What is the diameter of the image of the cell if it id magnified 400 times? PLS HELP. NEED IT QUICKLY TY
Attachment Below- help would be appreciated! :)
Answer:
A, B, C, E, and F
To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.
From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.
Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.
Hope this helped!
Find the area of the shaded region.
Answer:
75m2
Step-by-step explanation:
Usually, we would subtract the area of a smaller inner shape from the area of a larger outer shape in order to find the area of the shaded region.
The area of the shaded region is the difference between the areas of the rectangle and the square. The dimensions of the rectangle are 6 by 8 and so the area is 6 times 8, that is 48 square units. Each side of the square measures 2 units and so the area is 2 times 2, that is 4 square units.
Simplify (Write without absolute value sign)
ex) ║120 +x║, if x < -120
answer would be: -120 -x
My problems:
1. ║x-120║, if x<-120
2. ║x-(-12)║, if x > -12
3. ║x-(-12)║, if x < -12
4. ║x-(-12)║, if x = -12
5. ║x ÷ 3║, if x > 0
6. ║x ÷ 3║, if x < 0
7. ║x ÷ 3║, if x = 0
**WILL GIVE BRAINLIEST IF 4 OR MORE ARE CORRECT**
Answer:
-(x-120)
x-(-12)
-(x-(-12))
0
x / 3
-(x/3)
0
Step-by-step explanation:
1. || x-120||, if x<-120.
If x is less than -120, then x - 120 will be a negative number.
Since absolute value will make a negative number positive, the answer will be -(x-120).
2. ||x-(-12)||, if x > -12.
Basically x -(-12) = x + 12. If x is greater than -12, then ||x+12|| will be positive. The answer is x-(-12).
3. ||x-(-12)||, if x < -12.
Again, x-(-12) = x + 12. If x is less than -12, ||x+12|| will be negative.
Absolute value makes a negative number positive. The answer is -(x-(-12)).
4. ||x-(-12)||, if x = -12.
So we can substitute x with -12. ||-12-(-12)|| = ||-12+12||, which equals ||0||, which is also just 0. (Answer is 0.)
5. ||x / 3||, if x > 0.
Any positive number divided by another positive number will be positive, meaning you can just take out the absolute value sign. Answer is x /3.
6. ||x / 3||, if x < 0.
Any number less than 0 is negative, and any negative number divided by a positive number will be negative. If we take out the absolute value, we'll have to reverse it with a -. Answer: -(x/3).
7. ||x / 3||, if x = 0.
||0/3|| = ||0||, which is still 0.
Hope this helps!

Coach Riley asked 35 students to count the number of push-ups they completed during class. The results are displayed in the box plot.
He then asked them to complete 4 more by the end of class.
Which of the following statements is TRUE about a new plot with the altered data?
A - The range will Increase by 4 units
B - The median will be greater than 46.
C - The plot will be translated 3 units to the right.
D - The interquartile range will be 4 times larger.
Answer:
I think A
Step-by-step explanation:
In a wildlife preserve, a random sample of the population of 150 raccoons was caught and weighed. The results, given in pounds, were 16, 18, 18, 24, 25, 27, 28, 31, 31, and 32. Jean made the qualitative statement, "The average weight of the raccoon population is 26 pounds." Is her statement reasonable? Complete the explanation.
Jean's statement (select) reasonable because the median value of the data is pounds.
Answer:
The average is 24 so her answer is reasonable cause it is not too far off.
Step-by-step explanation:
Average = sum/count
(16 + 18 + 18 + 24 + 25 + 27 + 28 + 31 + 31 + 32)/10
240/10
24
24 is close to 26

Answer:
Shaded area is 55 units²
Step-by-step explanation:
Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is
(10 units)(7 units) = 70 units². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²
Subtract the latter from the former, obtaining the net area
70 units² - 15 units² = 55 units²

Answer:
6.2 and 7.0
Step-by-step explanation:
Your just adding 0.8
Answer:
- Blank space 1: 6.2
- Blank space 2: 7
Step-by-step explanation:
Each time the "b" row is going up by "0.8" so if 5.4, being the last given value is added to 0.8, it will give the value of 6.2 which can be added again with 0.8 to give the last value resulting in 7.
Hope this helps, good luck!

Answer:
Y = 2x + 1
Step-by-step explanation:
the slope is;
Change in "y" 2
-------------------- (over) = ------ or 2
Change in "x" 1
The y-intercept is the point in the graph where a point in slope touches the y- axis and.
In this case the point is (0,1) so the y-intercept is 1.

What is the area of triangle i? Show your calculation
please dont use me for points
Answer:
3 square centimeters.
Step-by-step explanation:
The measurements are 4 cm by 1.5 cm, so you can use the formula for area of a triangle (area = 1/2 * base * height) to figure it out.
Plug in base = 4, height = 1.5:
area = 1/2* 4 * 1.5 = 2 * 1.5 = 3.
The area is 3 sq. cm.

In the earlier Lesson Activity, you found the sizes of mesoplankton and jellyfish. In this activity, you’ll determine the most appropriate units for measuring the sizes of mesoplankton and jellyfish.
Part B
You also found the size of a jellyfish to be 2 meters. Do you think that meters are the most appropriate unit to represent the size of a jellyfish? If not, what do you think would be the most appropriate unit? Write the size of the jellyfish in the most appropriate unit.
Answer:
We did not read the lesson so we dont kown
I can answer the seocnd question i think no because as meters may be to small for some jellyfish as they come in diffrence sizes so i think millimeter are the prefect size.

I don't usually use this website anymore, but here's an answer I found for you.
Answer:
-14.57
Step-by-step explanation:
Subtract -2.67 by 5.95×2 since there were two days it equals -14.57
(Or)
-2.67 + x2 (x =-5.95)
-2.67 + (2*-5.95*) = -14.57
Part 1:
The account will be -14.57 after two days.
Step by step:
What I do is just forget the negatives until the end.
5.95 + 5.95 (two days) + 2.67 = 14.57
Bring back the negative: -14.57
