The amount of times that the the bacterial cell is smaller than the amoeba cell is; 150 times
How to use law of indices?
Laws of indices provide us with rules for simplifying calculations or expressions involving powers of the same base.
We are given;
Length of a bacterial cell = 3 * 10⁻⁶ m
Length of an amoeba cell = 4.5 * 10⁻⁴ m
Thus, to get the amount of times that the bacterial cell is smaller than the amoeba cell, we need to convert the Length of a bacterial cell to have same exponent as that of the Length of an amoeba cell before dividing.
Thus;
Length of a bacterial cell = 3 * 10⁻⁶ m
Length of an amoeba cell = 450 * 10⁻⁶ m
Thus, the amount of times that the the bacterial cell is smaller than the amoeba cell is;
(450 * 10⁻⁶)/(3 * 10⁻⁶) = 150 times

larger of two numbers is 13 more than twice the smaller number. the sum of the numbers is 52. find each number
Answer:
13 and 39
Step-by-step explanation:
let the smaller number be n then the larger number is 2n + 13 , so
n + 2n + 13 = 52
3n + 13 = 52 ( subtract 13 from both sides )
3n = 39 ( divide both sides by 3 )
n = 13
2n + 13 = 2(13) + 13 = 26 + 13 = 39
then smaller number is 13 and larger number is 39

The three equivalent ratios to 4/14 are:
b) 2/7c) 8/28d) 6/21.What is an equivalent ratio?Equivalent ratios are ratios having the same proportion to each other when they are put in their simplest forms.
Ratios are how much a variable is in relation to the whole. Ratios are the same as proportions or portions of the whole variable
Ratios can be shown as decimals, fractions, percentages, or with the ratio sign (:).
Data and Calculations:For instance, 2/5 = 0.4 or 40%
2/7 = 4/14 (2 x 2/7) or 0.2857
8/28 = 4/14 (4/14 x 2) or 0.2857
6/21 = 4/14 (4/14 ÷ 2 x 3) or 0.2857

Complementary Angles- When the sum of two angles is equal to 90 degrees, they are called complementary angles. (For example, 30 degrees and 60 degrees are complementary angles)
Supplementary Angles-Supplementary angles are those angles that sum up to 180 degrees. (For example, angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.)
Congruence Postulate- to be congruent if two angles and the side between these two angles of one triangle are congruent to corresponding angles and the included side (side between two angles) of the other triangle
Linear Pairs of Angles-A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

Answer:
Length = 12cm
Width = 8cm
Step-by-step explanation:
Let the length be x
Let the width be 2/3x
Perimeter = 2 (l+b)
Length = 2 (x+2/3x) = 40
= x + 2/3x = 40/2
= x + 2/3x = 20
= x/1 + 2/3x = 20
LCM = 3

= 3x + 2x = 20 x 3

During an experiment, the temperature of a mixture changes from 12 1/4°F to 15 3/5°F. What is the percent of the increase in the temperature of the mixture? I need an answer to the as a percent rounded to the nearest hundredth.
During the experiment the temperature changes slightly. Hence
the percentage increase in the temperature of the mixture is 27.35%.
Given, the temperature of the mixture changes from 12 1/4°F to 15 3/5°F
we are asked to determine the percentage of increase in the temperature of the mixture.
Initial temperature = 12 1/4°F
convert it into proper fraction.
= 48+1/4
= 49/4°F
Final temperature = 15 3/5°F
convert it into proper fraction.
= 75+3/5
= 78/5
Therefore, percentage increase:
= Final temp - Initial temp/Initial temp × 100
% Increase = (78/5 - 49/4)/49/4 × 100
% Increase = (78×4 - 49×5/5×4)/49/4 × 100
% Increase = 312-245/5×49 × 100
as 4 gets cancelled from numerator and denominator.
% Increase = 67×100/249
% Increase = 6700/249
% Increase = 27.346%
we need to round it off to the nearest hundredth.
% Increase = 27.35%
Hence the percentage increase in the temperature is 27.35%.

Answer:
f(3) = 3 - 3 --> f(3) = 0
f(x) = 12, x = 15 (because 15 - 3 would equal 12)
g(-3) = 2 (because in the chart for g(x), an x of -3 is 2)
g(x) = -3, x = 5 (because in the chart for g(x), a g(x) of -3 is an x of 5)
For the graph questions, p(0)= means that the 0 is the x integer and you must find the y when x=0
p(0) = 3
p(-4) = 5
p(1) = 3
p(x) = 1, x = 2
For the graph questions, p(x)=0 means that the 0 is the y integer and you must find the x when y=0
p(x) = 0, x = 2.5
p(x) = 5, x = -4
p(3) = -1
p(x) = 2, x = 1.5

Solve the proportion StartFraction one-fourth over 3 EndFraction = StartFraction p over 9 EndFraction to answer the question. Explain your steps.
Answer:3/4 teaspoons Trust me it is correct
The number of teaspoons of pepper required for beef is ( 3 / 4).
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that the recipe for beef stew calls for 1/4 teaspoon of pepper for every 3 potatoes the number of teaspoons required for 9 potatoes will be calculated as below:-
3 potatoes = ( 1 / 4 ) teaspoon
1 potato = ( 1 / 12 ) teaspoon
9 potatoes = 9 / 12 teaspoon
9 potatoes = 3 / 4 teaspoon

What is a z-distribution confidence interval?The confidence interval is as follows:
[tex]\overline{x} \pm z\frac{\sigma}{\sqrt{n}}[/tex]
The margin of error is given by the following rule:

The confidence level is of 95%, hence the critical value z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.
Then we take the margin of error equation and solve for n as follows:

What is distributive property of multiplication over addition ?
If we multiply a number by the sum of more than two, we use the distributive property of multiplication over addition.
In order to find the number of bags of potting soil sold over those two days, the first step is find out the number of pallets store sold there potting soil :
= 17( on Saturday) + 23 (Sunday)
= 40 palettes
Each palettes has 7 flats so the total number of flats sold is:
= 40 x 7
= 280 flats
Each flat then contains 7 bags so the total number of bags sold is:
= Number of flats sold x 7
= 280 x 7
= 1960 bags

The function F(x) = −0.005x 2 + 0.8x + 12 models the relationship between a certain vehicle’s speed and the fuel economy, where F(x) is the fuel economy in kilometres per litre and x is the speed of the vehicle in kilometre per hour.
a) Determine the average rate of change in the fuel economy in the interval of speed [60,80].
b) b) Interpret your result.
The average rate of change in the fuel economy in the interval of speed [60,80] is 0.1
The given function F(x) = −0.005x 2 + 0.8x + 12 models the relationship between a certain vehicle’s speed and the fuel economy
where F(x)= fuel economy in kmpl
x =speed of the vehicle in km/h
we need to find the average rate of change in the fuel economy in the interval of speed [60,80].
At speed 60 km/h
the fuel economy = - 0.005(60²) + 0.8(60) +12
= - 18 + 48 + 12
= 42 kmpl
At speed 80 km/h
the fuel economy = - 0.005(80²) + 0.8(80) +12
= - 32 + 64 + 12
= 44 kmpl
the average rate of change is given by the formula = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
By substituting the values we get= [tex]\frac{44- 42}{80-60}[/tex]
= 2/ 20
= 0.1
Hence, The average rate of change in the fuel economy in the interval of speed [60,80] is 0.1 which reflects that for increase in every one kilometer there is increase in fuel economy by 0.1

Hey there!
|6w - 18| = 12
You can say:
|6w - 18| = 12
6w - 18 = 12 or 6w - 18 = -12
First let’s solve for: 6w - 18 = 12
6w - 18 = 12
ADD 18 to BOTH SIDES
6w - 18 + 18 = 12 + 18
SIMPLIFY IT!
6w = 12 + 18
6w = 30
DIVIDE 6 to BOTH SIDES
6w/6 = 30/6
SIMPLIFY IT!
w = 30/6
w = 5
Second let’s solve for: 6w - 18 = -12
6w - 18 = -12
ADD 18 to BOTH SIDES
6w - 18 + 18 = -12 + 18
SIMPLIFY IT!
6w = -12 + 18
6w = 6
DIVIDE 6 to BOTH SIDES
6w/6 = 6/6

what is the linear equation that has a y-intercept of -4 and a x-intercept of -5
The linear equation that has a y-intercept of -4 and a x-intercept of -5 s y = -4/5x - 4
Equation of a lineThe equation of a line in slope intercept form is expressed y = mx + b
where
m is the slope
b is the y-intercept
Given the coordinate points (0, -4) and (-5, 0), the slope is calculated as:
Slope = y₂-y₁/x₂-x₁
Slope = 4/-5
Slope = -4/5
Determine the equation
y = -4/5x + (-4)
y = -4/5x - 4
Hence the linear equation that has a y-intercept of -4 and a x-intercept of -5 s y = -4/5x - 4
