Answer:
the answer was 24
Step-by-step explanation:
Activity
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 A
Earlier, you found the size of a mesoplankton to be 2 x 102 meter. Do you think that meters are the most appropriate unit to represent the size
of a mesoplankton? If not, what do you think would be the most appropriate unit? Write the size of a mesoplankton in the most appropriate unit.
Answer:
No.
The most appropriate unit to measure the mesoplankton is centimeter.
The size is 2 cm.
Step-by-step explanation:
Earlier, you found the size of a mesoplankton to be [tex]2 \times 10^{-2}[/tex] meter.
I think that meters are not the most appropriate unit to represent the size of a mesoplankton.
The most appropriate unit to measure the mesoplankton is centimeter.
Now, 1 meter is equivalent to 100 centimeters.
So, the size of the mesoplankton in centimeter units will be [tex]2 \times 10^{-2} \times 100 = 2[/tex] cm. (Answer)
Final answer:
Meters are not the most appropriate unit for the size of a mesoplankton; millimeters are more suitable considering the small size of these organisms. The size 2 x 10² meters seems to be a typo and should likely be a much smaller value, such as 2 millimeters.
Explanation:
No, meters are not the most appropriate unit to represent the size of a mesoplankton. Considering that a mesoplankton is quite small, much smaller than objects like a piece of paper or a human's wingspan, using meters would not provide a practical or convenient measurement scale.
Since mesoplankton are small, it is important to think about units that are suitable for measuring very small objects. Given the metric units millimeters and centimeters are the next best alternatives. In this case, centimeters, being smaller than meters are a better match for the size of mesoplankton, but even centimeters might be too large.
Therefore, the most appropriate unit of measurement for the size of a mesoplankton is likely to be in millimeters. Therefore, 2 x 10^2 meters (200 meters) appears to be a typo, as mesoplankton would typically measure less than 2 centimeters. Assuming the intended measurement was supposed to be much smaller, converting to millimeters would be the best approach. An actual mesoplankton might measure around 2 millimeters, though this is just an example since the original measurement given seems incorrect.

What must be subtracted from a3b+6a2b2 -7ab+4 to get -7a2b2+2a3b+6ab-1?
[tex]-a^{3} b+13 a^{2} b^{2}-13 a b+5[/tex]
Step-by-step explanation:
Let x be the expression, we have to find must be subtracted from the given expression, to get the answer.
Now we have to combine the like terms, before that we have to move x from LHS to the RHS , so that we will get the required expression.
[tex]a^{2} b+6 a^{2} b^{2}-7 a b+4-x=-7 a^{2} b^{2}+2 a^{2} b+6 a b-1[/tex]
[tex]a^{3} b+6 a^{2} b^{2}-7 a b+4+7 a^{2} b^{2}-2 a^{3} b-6 a b+1=x[/tex]
Now arranging the like terms as,
[tex]\begin{array}{l}a^{3} b-2 a^{3} b+6 a^{2} b^{2}+7 a^{2} b^{2}-7 a b-6 a b+4+1=x \\-a^{3} b+13 a^{2} b^{2}-13 a b+5=x\end{array}[/tex]
So the expression is "[tex]-a^{3} b+13 a^{2} b^{2}-13 a b+5[/tex]"
(-2h3n2)(-5h2n2)
How
Answer: 9h x 8n^2
we rearrange this underneath the question (-5h-2h) (2nx3n)(2+2) or if 2^2 see explanation. It must therefore be 7h6n4
Step-by-step explanation:
if its ^2 )(power2) then the second reasonable answer is (7h-2h)(2n^2 x 2n^2)=9h x 4n^2 x4n^2 =9h 8n^2 or 17hn^2 but i leave as 9h 8n^2
You can expand only if multiplying 9hx4 for example but not combine the letters. The questions that ask you to mix are much different to this. but if you want to add them 9h+8n^2 =17hn^2

Sarah has a bag of 50 skittles, some are red and some are yellow. Sarah randomly pulls a skittle out of the bag and records it, and returns it back to he bag.so far she has recorded 8 reds and 12 yellows.based on these results what is the MOST likely numbers of reds in the bag?
Answer:
20
Step-by-step explanation:
Assume n is the number of times she pick a skittle out of the bag
The probability she pick out red : 8/n
The probability she pick out yellow : 12/n
=> The ratio of red and yellow skittle : 8/n : 12/n = 8/12 = 2/3, means every 2 red skittles we have 3 yellow ones.
But we have 50 skittles, so the likely numbers of reds in the bag is = 2*[tex]\frac{50}{5}[/tex] = 20
Solve for n
5n - 3 = 17
Answer: n=4
Step-by-step explanation:

Katie has 6500 in her savings account. If it earns 6% interest every month how much savings does she have in her account in over half a year
Step-by-step explanation:
First, you recognize the algorithm for the equation: A=P(1+r)^n. This is the algorithm for interest. P is the amount of initial money (in this case, 6500), r is the interest rate (6%, or 0.06), and n is the number of times it is being compounded. Since half a year is given to me, 6 months is what I will be using, or just 6.
Next, plug in the numbers. The equation is now: A=6500(1+0.06)^6.
Now time to solve. First add what's in the parenthesis, and put it to the power of 6, for 6 months. Then multiply that amount to the initial dollar amount; 6500. This will leave you with 9,220.37.

=20+8n-8
=20-8+8n
=12+8n
The arithmetic equation is 12+8n
Algebra 1, Section 7.09
Answer:
b. 4
Step-by-step explanation:
Given f(x) = 4x - 4 and g(x) = x - 1, we can find (f/g)(x) by dividing f(x) by g(x):
(f/g)(x) = (4x - 4)/(x - 1)
Now, substituting x = -4 into the expression
(f/g)(-4) = (4*(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4
Therefore, the correct answer is b. 4.
Given the function g(x) = x - 1, let's solve (f/g)(-4) using the function f(x) = 4x - 4.
To find (f/g)(-4), we need to evaluate the expression (f(x)/g(x)) at x = -4.
First, let's find the value of f(x)/g(x) for any x:
(f/g)(x) = f(x)/g(x) = (4x - 4)/(x - 1)
Now, substituting x = -4 into the expression:
(f/g)(-4) = (4(-4) - 4)/((-4) - 1) = (-16 - 4)/(-5) = -20/-5 = 4
Therefore, the correct answer is b. 4.
Which of the following coordinate points is the point of intersection of these two lines? y - 6x = -4 y - 2x = 8 Question 4 options: (−1/2, 7) (12/8,11) (9/6,5) (3, 14)
Option D: [tex](3,14)[/tex] is the point of intersection of the two lines.
Explanation:
The two equations are [tex]y-6 x=-4[/tex] and [tex]y-2 x=8[/tex]
We need to find the point of intersection of the two lines.
Thus, let us solve the equation by substitution method.
From the equation [tex]y-6 x=-4[/tex], we shall determine the value of y, by adding both sides of the equation by 6x.
Hence, we have, [tex]y=6x-4[/tex]
Now, substituting [tex]y=6x-4[/tex] in the equation [tex]y-2 x=8[/tex] , we get,
[tex]6x-4-2 x=8[/tex]
[tex]4x-4=8[/tex]
[tex]4x=12[/tex]
[tex]x=3[/tex]
Substituting [tex]x=3[/tex] in the equation [tex]y-6 x=-4[/tex], we get,
[tex]y-2 (3)=8[/tex]
[tex]y-6=8[/tex]
[tex]y=14[/tex]
Thus, the point of intersection of the two lines is [tex](3,14)[/tex]
Therefore, Option D is the correct answer.

Step-by-step explanation:
Answer:
Approximately 93 million.
Step-by-step explanation:
If Venus is 67 million miles from the sun, and Earth is 26 million miles from Venus, then you would need to add the distance from Earth to Venus to the distance from the sun to Venus
67,000,000 + 26,000,000 = 93,000,000
A utility pole is supported by two wires, one on each side, going in the opposite direction. The two wires form a 75-degree angle at the utility pole. if the wires are 12 meters and 16 meters long and secured to the ground, find the distance between the wires on the ground.
(Cosines problem)
Answer:
The required distance is 17.34 meters.
Step-by-step explanation:
The lengths of the two wires are 12 meters and 16 meters. and the angle between the wires is 75°.
Now, we have to calculate the distance between the wires on the ground.
Therefore, we have to calculate the length of the side which is the opposite side of angle 75° of the triangle formed by the wires and the ground.
Applying the formula of properties of the triangle, if the length required is x, then
[tex]\cos 75^{\circ} = \frac{12^{2} + 16^{2} - x^{2}}{2 \times 12 \times 16}[/tex]
⇒ 99.38 = 144 + 256 - x²
⇒ x = 17.34 meters. (Answer)
