The radius of the hole to the nearest hundredth of a foot is 2.88 feet.
What is radius?
The separation between a circle's centre and circumference is called the radius.Its diameter is halved that of the circle.The path that leads from a circle's centre to one of its points.The separation between a circle's centre and a certain point upon that circle.The volume of the cylinder, V = 4200 cubic feet
Height, H = 2.1 miles = 11088 feet
The volume of the cylinder is given by the formula, V =πr²H
Putting values in the formula to find out radius,
4200=πr²(11088)
r²=[(11088)π]/4200
r²=8.2938
r=2.879~2.88 feet
The radius of the hole to the nearest hundredth of a foot is 2.88 feet.

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

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

find the equation that is perpendicular to the line 8x-6y=-5 and passes through (1,-3)
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.
∴ The equation of the line is y = (-3/4)x - 9/4.

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.
