what is the difference between slope and a common ratio?
Answer:they are solved in a different manner
Step-by-step explanation:
Step-by-step explanation:
slope:
In math, slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.
common ratio:
The constant factor between consecutive terms of a geometric sequence is called the common ratio.
Example: To find the common ratio , find the ratio between a term and the term preceding it. r=42=2. 2 is the common ratio.

Based on equation of the line of best fit how much money should Millie expect to earn if he works a five hour shift?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]x = 5[/tex] ---- 5-hour shift
Required
The expected earnings
The question is incomplete, as the equation is not given. A general way to solve this, is to substitute the value of x in the equation, then solve for the y variable.
Take for instance, the equation is:
[tex]y = 10x + 2[/tex]
The expected earnings will be:
[tex]y = 10*5 + 2[/tex]
[tex]y = 50 + 2[/tex]
[tex]y = 52[/tex]
Expected Earnings = $52

An investment of $100 is now valued at $149.18 the interest rate is 8% compounded continuously about how long has the money been invested
question: An investment of $100 is now valued at $149.18 the interest rate is 8% per year, compounded continuously about how long has the money been invested
Answer:
5.2 years
Step-by-step explanation:
Applying
A = P(1+R/100)ⁿ.......................... Equation 1
Where A = amount, P = principle, R = rate, n = time.
From the question,
Given: A = $149.18, P = $100, R = 8%
Substitute these values into equation 1 and solve for n
149.18 = 100(1+8/100)ⁿ
149.18/100 = (1+8/100)ⁿ
1.4918 = (1+0.08)ⁿ
1.4918 = (1.08)ⁿ
Taking the Logarithm of both side
Log(1.4918) = Log(1.08)ⁿ
Log(1.4918) = nLog(1.08)
n = Log(1.4918)/Log(1.08)
n = 0.1737/0.0334
n = 5.2 years.

A frosting is made of cream cheese and powdered sugar in the ratio 3:2. If you use 120g or cream cheese, how much powdered sugar should you use
Answer: 80 g
Step-by-step explanation:
Given
The frosting is made of cream cheese and Powdered sugar in the ratio of 3:2.
If 120 g of cheese is used
Assume the quantity of powdered sugar is x
So, we can write the ratio as
[tex]\Rightarrow \dfrac{3}{2}=\dfrac{120}{x}\\\\\Rightarrow x=\dfrac{2}{3}\times 120\\\\\Rightarrow x=\dfrac{2}{3}\times 3\times 40\\\\\Rightarrow x=80\ g[/tex]
So, 80 g of powdered sugar is used.
Answer: 80grams
Step-by-step explanation: pretty simple 120/3=40. 40x2=80 grams. Sorry for explanation not being really clear.

Have a Nice Day
Answer:
it's D.
Step-by-step explanation:
Find the measure of side c. Triangle A B C has a right angle at angle C. The measure of angle A is 29 degrees. Hypotenuse A B is labeled "c" and leg B C is labeled "a = 33 meters." 29 o c a = 33 m
Given:
In triangle ABC, right angle at angle C.
[tex]a = 33[/tex] meters
[tex]m\angle A=29^\circ[/tex]
To find:
The measure of side c.
Solution:
In a right angle triangle,
[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
It is also written as:
[tex]\sin \theta =\dfrac{Opposite}{Hypotenuse}[/tex]
In triangle ABC, angle C is a right angle. It means the side c is the hypotenuse.
In triangle ABC,
[tex]\sin A=\dfrac{a}{c}[/tex]
[tex]\sin 29^\circ=\dfrac{33}{c}[/tex]
[tex]c=\dfrac{33}{\sin 29^\circ}[/tex]
On further simplification, we get
[tex]c=\dfrac{33}{0.4848}[/tex]
[tex]c=68.0693[/tex]
[tex]c\approx 68.07[/tex]
Therefore, the measure of side c is 68.07 meters.
What is m∠BAC.
............
Answer:
37 degrees
Step-by-step explanation:
1. m∠CBA = 71+45 = 116 degrees
2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.
3. m∠CBA + m∠CDA = 2*116 = 232.
4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.
5. m∠BAD = m∠BCD = 128/2 = 64 degrees
6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees

Find the mode, median, mean and range for this set of data.
Number of Hours Slept: 8.5, 7,6.75,5.75, 8.75,6.25,7,7.5, 4.25
Central Tendency is the statistical measure that can be used to represent all the distribution or a dataset using a single value. The most common measures of central tendency are the mode, median, and mean.
How to determine this
Mode is the value that has the highest frequency in a given data set.
So,
8.75 the highest frequency in the data set
Mode = 8.75
Median is the middle of a sorted list of numbers when arranged in ascending order.
So,
4.25, 5.75, 6.25, 6.75, 7, 7, 7.5, 8.5, 8.75 in ascending order
Median = 7
Mean is the average or the most common value in a given set of values.
Mean = 8.5 + 7 + 6.75 + 5.75 + 8.75 + 6.25 + 7 + 7.5 + 4.25/9
Mean = 61.75/9
Mean = 6.8611
Mean = 6.86 to 2 decimal place
Range is the difference between the highest value and lowest values.
Range = Maximum value - Minimum value
Range = 8.75 - 4.25
Range = 4.5

Can someone please show me how to do this, I know the answer is 125 a^3 b^2.
The question is shown below in a picture I’m not sure how to do it please explain!
Answer:
Step-by-step explanation:
5^4 = 625. I hope your calculator will do this.
625 / 5 = 125
There is a more general way to do this which will be in harmony with the rest of the question.
5^4 / 5^1 = 5^(4 - 1) = 5^3 = 125
b^4 / b2 = b^(4 - 2) = b^2
a remains as it is at a^3
So the answer is 125 a^3 b^2
Emma bought a pair of earrings, a dress and a coat. The dress cost 6 times as much as the earrings, and the coat cost 13 times as much as the earrings. If the three items cost a total of $3200, how much did each of them cost?
Answer:cost of earring=$160
cost of dress= $960
cost of coat =$2,080
Step-by-step explanation:
Let cost of earring be represented as x
so that the cost of dress =6x
And the cost of coat =13x
Since the three items cost a total of $3200, we can develop an equation which can be represented as
cost of earring+cost of dress +cost of coat =3200
x +6x+13x=3200
20x =3200
x=3200/20=160
THerefore cost of earring=$160
cost of dress= 6x =$160 x 6=$960
cost of coat = 13x = $160 x 13=$2,080

A car lot has both used and new cars. If 86% of the cars on the lot are new and 45% of the cars are new and have a sunroof, find the probability of randomly choosing a car with a sunroof, given that it is a new car
Answer:
0.523
Step-by-step explanation:
Let :
New car = N
Sunroof = S
P(N) = 0.86
P(N n S) = 0.45
Recall :
P(A|B) = p(AnB) / p(B)
Therefore ;
P(S|N) = P(SnN) / p(N)
P(S|N) = 0.45 / 0.86
P(S|N) = 0.523
