The length of a bacterial cell is about 5.36 x104 m, and the length of an amoeba cell is about 6.2 x 104 m.
Thus length of a bacterial cell is 0.864 times of length of an amoeba cell.
Given that the length of a bacterial cell is about 5.36 x 10⁻⁴ m, and the length of an amoeba cell is about 6.2 x 10⁻⁴ m.
Ratio of the size of the cell is
B/A = 5.36 x 10⁻⁴/6.2 x 10⁻⁴
B/A = 5.36/6.2
= 0.864
Thus length of a bacterial cell is 0.864 times of length of an amoeba cell.

Ernesto guesses there are 69 marbles in a jar, but there are actually 60.
What is the percent error in Ernesto's guess?
Answer:
15%
Step-by-step explanation:
Since the problem is to find how much 69 is as a percent if 60 is 100%, we can use a rule of three, simple, direct proportion to do it:
60 = 100%
68 = x
x = 69x100/60
x = 115
That means 69 is 115% of 60, which means that the error is of:
115 - 100 = 15%

The measure of angle A is 4° greater than the measure of angle B. The two angles are complementary. Find the measure of each angle.
Answer:
A: 49° B: 41°
Step-by-step explanation:
First, you know they are complementary, so they must be at least 45°. Then, since angle A is 4° greater than angle B, you add 4° to angle A (49°) and subtract 4° from angle B (41°).
Bridgette has 9 dogs. Every day, she feeds them a total of 9/10 of a can of food, where each dog is fed the same amount of food. How many cans of food does Bridgette give to each dog?
Bridgette gives 1/10 cans of food to each dog.
According to the question,
We have the following information:
Bridgette has 9 dogs. Every day, she feeds them a total of 9/10 of a can of food, where each dog is fed the same amount of food.
Now, we have the following expression:
9 dogs = 9/10 can
Now, we can easily find the cans given to each dog using division. We will divide the total number of cans of food by the number of dogs.
1 dog = 9/(10*9) cans
1 dog = 1/10 cans of food
Hence, Bridgette gives 1/10 cans of food to each dog.

emmanuel is 2 times older than jamie. their ages add to 54. Find both their ages
Answer:
Emmanuel is 28, and Jamie is 26
Step-by-step explanation:
54/2=27
28-emmanuel
26-jamie
28+26=54
If Emmanuel is 2 times older than Jamie, their ages add to 54 Jamie is 18 years old and Emmanuel is 36 years old.
Determining their agesLet's assume Jamie's age is x.
Emmanuel's age is 2 times older than Jamie's age, so Emmanuel's age is 2x.
The sum of their ages is 54, that is
x + 2x = 54
Combining like terms:
3x = 54
Dividing both sides by 3:
x = 54/3
x = 18
Jamie is 18 years old.
Substituting Jamie's age back into the equation to find Emmanuel's age:
Emmanuel's age = 2 * Jamie's age
Emmanuel's age = 2 * 18 = 36
Emmanuel is 36 years old.
Therefore, Jamie is 18 years old and Emmanuel is 36 years old.

A doctor prescribes an ointment that is 2% hydrocortisone. A pharmacist has 1% and 5% concentrations in stock. How many ounces of each should the pharmacist use to make a 7-ounce tube?
The pharmacist should use 5.25 ounces of 1% hydrocortisone ointment and 1.75 ounces of 5% hydrocortisone ointment.
How to find ounces ?Let x be the number of ounces of 1% hydrocortisone ointment required and y be the number of ounces of 5% hydrocortisone ointment required to make a 7-ounce tube of 2% hydrocortisone ointment.
Since we want a total of 7 ounces of ointment, we have the equation:
x + y = 7
We also know that the amount of hydrocortisone in the final ointment must be equal to 2% of 7 ounces, or 0.14 ounces. The amount of hydrocortisone in x ounces of 1% ointment is 0.01x ounces, and the amount of hydrocortisone in y ounces of 5% ointment is 0.05y ounces. So, we have the second equation:
0.01x + 0.05y = 0.14
To solve for x and y, we can use the method of substitution. Rearranging the first equation to solve for x, we get:
x = 7 - y
Substituting this expression for x into the second equation, we get:
\(0.01(7 - y) + 0.05y = 0.14\)
Simplifying and solving for y, we get:
0.07 - 0.01y + 0.05y = 0.14
0.04y = 0.07 - 0.14
0.04y = -0.07
y = -0.07/0.04
y = -1.75
This negative value for y doesn't make sense, so we need to check our work. We made a mistake in the equation above, the correct equation should be:
0.01x + 0.05y = 0.02(7)
0.01x + 0.05y = 0.14
Using this corrected equation, we can solve for y:
0.01x + 0.05y = 0.14
0.05y = 0.14 - 0.01x
y = (0.14 - 0.01x)/0.05
Substituting this expression for y into the first equation, we get:
x + (0.14 - 0.01x)/0.05 = 7
Multiplying both sides by 0.05 to eliminate the denominator, we get:
0.05x + 0.14 - 0.01x = 0.35
0.04x = 0.21
x = 5.25
So, the pharmacist should use 5.25 ounces of 1% hydrocortisone ointment and 1.75 ounces of 5% hydrocortisone ointment to make a 7-ounce tube of 2% hydrocortisone ointment.

evaluate the integral. (remember to use absolute values where appropriate. use c for the constant of integration.) dt t2 − 12t 40
The integral of t² - 12t + 40 with respect to t is equal to (1/3)t³ - 6t² + 40t + C, where C is the constant of integration.
Explanation: This can be determined by using the power rule of integration, where the antiderivative of tⁿ (where n is a positive integer) is (tⁿ⁺¹)/(n+1) + C.
For example, the antiderivative of t² is (1/3)t³ + C, and the antiderivative of -12t is -6t² + C.
Finally, the antiderivative of a constant, such as 40, is simply 40t + C. So, when we add up all the antiderivatives, we get the integral of t² - 12t + 40 with respect to t, which is equal to (1/3)t³ - 6t² + 40t + C.

value of the maximum moment in kN-m
When a simply supported beam carries a uniform load of 104 kN/m over a length of 10 m, the absolute value of the maximum moment is 1300 kN-m.
The maximum moment in a simply supported beam carrying a uniform load can be determined using the formula:
Mmax = \((w * L^2) / 8\)
where Mmax is the maximum moment, w is the uniform load, and L is the length of the beam.
In this case, the uniform load is given as w = 104 kN/m, and the length of the beam is L = 10 m.
Plugging these values into the formula, we have:
Mmax = \((104 * 10^2) / 8\)
Simplifying the equation:
Mmax = (104 * 100) / 8
Mmax = 1300 kN-m
Therefore, the absolute value of the maximum moment in this beam is 1300 kN-m.

When Nellie Newton hangs at rest in the middle of a clothesline, tensions will be the same in each side of the rope when:
a. the lengths of each rope are the same
b. the angles for both sides of the rope are equal
c. she is in equilibrium
The tensions in each side of the rope will be the same when Nellie Newton hangs at rest in the middle of a clothesline and the lengths of each rope are the same.
When Nellie Newton is in equilibrium, meaning she is at rest and not experiencing any acceleration or movement, the forces acting on her must be balanced. In the case of a clothesline, the tension in each side of the rope contributes to the balancing of forces.
For the tensions to be the same in each side of the rope, the lengths of the ropes must also be the same. This ensures that the forces applied to each side are equal and balanced, resulting in Nellie Newton remaining in a stable position without any net force acting on her.

a projectile is shot straight up from the earth's surface at a speed of 1.30×104 km/hr. How high does it go?
Therefore, the projectile goes approximately 6.9 × 10^6 meters or 6,900 kilometers high.
Let's first convert the initial speed from km/hr to m/s to be consistent with the unit of acceleration due to gravity.
1.30×10^4 km/hr = (1.30×10^4 × 1000 m/km) / (3600 s/hr) = 3611.11 m/s
We can use the kinematic equation: Δy = v0t + 1/2at^2 to determine the maximum height reached by the projectile. At the highest point, the velocity is zero, so we can use the fact that v = v0 + at = 0 to find the time it takes to reach the maximum height.
v0 = 3611.11 m/s (initial velocity)
a = -9.81 m/s^2 (acceleration due to gravity)
t = -v0/a = -3611.11/(-9.81) = 367.97 s (time to reach maximum height)
Now we can use the time to find the maximum height reached:
Δy = v0t + 1/2at^2 = 3611.11 × 367.97 + 1/2 × (-9.81) × (367.97)^2 ≈ 6.9 × 10^6 meters

Answers:
a = 3
b = 3
c = -6
=====================================
Explanation:
The roots are x = 1 and x = -2. This leads to the factors x-1 and x+2 respectively.
This is because something like x = 1 becomes x-1 = 0 after subtracting 1 from both sides. For x = -2, we add 2 to both sides getting x+2 = 0.
The factorization is y = a(x-1)(x+2)
Plug in (x,y) = (2,12) and solve for 'a'
y = a(x-1)(x+2)
12 = a(2-1)(2+2)
12 = a(1)(4)
12 = 4a
12/4 = a
3 = a
a = 3
So we have y = a(x-1)(x+2) update to y = 3(x-1)(x+2)
--------------------------------------
The last thing we need to do is expand everything out (use the FOIL rule then distributive rule) to get the equation into standard form
y = 3(x-1)(x+2)
y = 3(x^2+2x-1x-2)
y = 3(x^2+x-2)
y = 3x^2+3x-6
Comparing this to y = ax^2+bx+c shows that:
a = 3
b = 3
c = -6

Geomotry 10th grade easy 25 points
Answer: 1=60°
Step-by-step explanation:
First, let's take our given angle of 30°
30° is in a right triangle, so the angles must be 90°, 60°, and 30°
Now the angle that is 45° makes angle 1 congruent to angle 60°
Meaning angle 1 is 60°
Answer:
m < 1 = 60
Step-by-step explanation:
Since the transversal is perpendicular to m,
it implies that the triangle formed by the perpendicular transversal, the slant transversal and the line m is a right angle triangle.
We use vertically opposite angles property to bring m<1 in to the right triangle.
We now use the sum of interior angles property to obtain,
m < 1 + 30 + 90 = 180
This implies that,
m < 1 + 120 + 180
We group like terms to obtain,
m < 1 = 180 - 120
This means that,
m < 1 = 60
We could have also used corresponding angles property, then
m < 1 + 30 = 90
m < 1 = 90 - 30
m < 1 = 60
