What do you mean by percentage?It is not always obvious from the context what a % is in relation to because of inconsistent usage. The typical meaning of a "10% rise" or "10% decline" in a quantity is that this refers to the quantity's starting value. As an illustration, the new price of a $200 item would be $220 if the price increased by 10%, or $20. The final price is equal to 100% of the starting price (100% + 10% = 110%).
Other instances of % changes include:
If a quantity is increased by 100%, the final amount will be 100% more than the original amount (100% of initial + 100% of increase = 100% of initial). The quantity has therefore doubled.
If an amount is increased by 800%, the final sum will be nine times as large as the original (100% + 800% = 900% = 9 times as large).
When something is reduced by 60%, the final sum equals 40% of the original (100% - 60% = 40%).
A reduction of 100% results in a final value of 0% (100% - 100% = 0%).
In general, if a quantity is changed by x percent, the final amount will be 100 + x percentage of the original amount, or (1 + 0.01x) times the original amount.

Answer:
A. The total number of hours it takes to make dresses and skirts each month
Step-by-step explanation:
By multiplying the amount of time to make an item by the amount of items made, you get the total amount of time spent on making those items. Therefore the total time spent making dresses is 8x, and the total time spent making skirts is 3y, which means that the total time to make both is 8x+3y.
Dorothy wants to purchase a car. She reviewed her budget and can comfortably afford a car payment of $490 per month. She has good credit and anticipated being able to secure a 4-year loan at 4% interest.What is the maximum cost she should pay for a car to stay within her budgeted monthly amount?
$21702.
$19762.
$16185.
$10386.
The maximum cost Dorothy should pay for the car to stay within her monthly budget amount is $23,518.84. See the explantion below.
What is a budget?A budget is a financial plan that takes into account both income and costs. In other words, it's a projection of how much money you'll make and expend over a specific time period, such as a month or a year.
The calculation that justified the above amount is solved as follows:
Given that:
Rate = 4%
Time = 4 years
The monthly payment is $490, to determine the amount (maximum) in 4 years, we use the Compound Interest formula:
A = P (1+ (r/n)ⁿᵇ
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
b = number of time periods elapsed
A = P (1 + (0.04/1)^(1x4)
A = P (1.04)⁴ in four years
Hence, given that the monthly payment over the four-year period is $490, we say:
P [(1.04)⁴] /12 x4 = 490
⇒ P (1.04)⁴ = 490 x 48
P = (490 x 48)/1.1699
P = 20104.2824173
P [tex]\approx[/tex] 20,104
The maximum amount payable hence
= 20,104 (1.04)⁴
A = 23518.837
A [tex]\approx[/tex] 23,518.84

Jack and Jill took a trip to Grandma’s house. It took them 8 hr to get to Grandma’s house but on their way back home they took the scenic route, which is 20 mi longer. If their speed going home was 10 mi/hr less than their speed going to Grandma’s house, and if it took them 10 hr to get home, how far did they travel going to Grandma’s and what was their average speed on the trip there?
Answer:
Let s be the distance to Grandma’s and v the speed they went to get to Grandma’s.
So s=8v, because it took them 8 hours to get there.
Coming back they travelled s+20 miles. Since s=8v we can write this as 8v+20 miles.
Their speed was reduced by 10mph so that’s v-10. It took them 10 hours to return so:
8v+20=10(v-10); 8v+20=10v-100; 120=2v
so v=60mph. This is their average speed going to Grandma’s.

The proportionality is the direct relation of two variables thus the constant of proportionality of the given graph is 1/2.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
For example x ∝ y
The graph of seconds and ounces has shown.
If we look at the graph it is clear that as the ounces are increasing the seconds are also increasing. Therefore, it is a direct proportion.
Let's suppose the proportion is x ∝ y where x is ounces while y is seconds.
Removing proportionality,
x = ky
k = x/y
Substitute,(x,y) = (1,2)
k = 1/2

pls help omg its 2am and i need to get this done by tomorrow
The equation of the perpendicular line in slope intercept form is
y = (-3/4)x - 9/4.
What is the slope?The slope is defined as the rate of change of the y-axis with respect to
x-axis.
We know equation of a line in slope intercept form is y = mx + b, where slope = m and y-intercept = b.
We also know that perpendicular lines have a slope that is negative reciprocal of each other.
Given line is 8x - 6y = -5.
-6y = - 8x - 5.
-y = (-8/6)x - 5/6.
-y = (-4/3)x - 5/6.
y = (4/3)x + 5/6.
∴ Slope(m) = 4/3.
So, the line which is perpendicular has a slope(m) = -3/4 with points (1,-3).
∴ - 3 = (-3/4)(1) + b.
- 3 = -3/4 + b.
b = 3/4 - 3.
b = -9/4.

find the circumference and area if its 56 cm
If the diameter of the circle is 56cm² then the circumference of the circle is 176cm and the area of the circle is 2464cm².
How do you determine a circle's area?A circle's area is equal to pi times the radius squared (A = πr). Discover how to apply this formula to determine a circle's area given its diameter.
Area of Circumference: What Does It Mean?The length of a circle's outline is referred to as its circumference, while the length of a form with straight sides is referred to as its perimeter. Circle circumference equals 2πr.
The circle has a 56 cm diameter, determine its circumference and area.Diameter of the circle =56cm
Radius of circle =56/2 =28cm
Therefore,
Circumference of circle
=2πr
=2*22/7*28
