A cylinder has a radius of 15 millimeters and a height of 17 millimeters.
What is the approximate volume of the cylinder?
O 3,004 cubic millimeters
O 3,405 cubic millimeters
O 12,017 cubic millimeters
O 13,619 cubic millimeters
Answer:
O 12,017 cubic millimeters
Step-by-step explanation:
Volume of cylinder = height x cross-section area(in this question, it's a circle) = hpr^2

Subtraction:
Subtraction represents the operation of removing objects from a collection. The minus sign signifies subtraction −. For example, there are nine oranges arranged as a stack (as shown in the above figure), out of which four oranges are transferred to a basket, then there will be 9 – 4 oranges left in the stack, i.e. five oranges. Therefore, the difference between 9 and 4 is 5, i.e., 9 − 4 = 5. Subtraction is not only applied to natural numbers but also can be incorporated for different types of numbers.
The letter "-" stands for subtraction. Minuend, subtrahend, and difference are the three numerical components that make up the subtraction operation. A minuend is the first number in a subtraction process and is the number from which we subtract another integer in a subtraction phrase.

A shoe store marks up the price of shoes by 35%. Jill wants to buy a pair of shoes that cost $135. What was the wholesale price?
The wholesale price of the pair of shoe Jill bought is 100 dollars.
How to find the wholesale price of the shoe?Mark up is the difference between a product's selling price and cost as a percentage of the cost.
The shoe store marks up the price of shoes by 35%. Jill wants to buy a pair of shoes that cost $135. The wholesale price of the of the shoe can be calculated as follows:
mark up % = 135 - x / x × 100
where
x = wholesale price35 = 13500 - 100x / x
cross multiply
35x = 13500 - 100x
35x + 100x = 13500
135x = 13500
divide both sides by 135
x = 13500 / 135
x = 100 dollars

Please be as detailed as possible with your explanation so I can get a sense of how you came to your conclusion, thank you.
After using the linear regression we would have the value for a and b. a and b represent the slope (a) of a line and the y-intercept (b).
To find the values of the equation we must round the results of the linear regression to the nearest integer
a would be equal to -2 as the number -1.96341463 is nearer to -2 than -1.
b would be equal to 19 as the number 19.09756098 is nearer to 19 than 20.
The final equation would be:
y= -2x + 19
Britta made her last monthly interest-only payment on may 5. her next
payment is due on june 5. what will be the amount of that interest-only
payment?
The amount of that interest-only payment is $21.53.
Define interestsThe term "interest" refers to the extra money an investor makes on top of their investment or the extra money a borrower owes on top of the money they've been loaned. Along with the loan itself, there is an additional sum or interest that must be paid.
Interests come in two types: simple interest and compound interest.
Given,
She has been awarded a $6,000 for 10-year federal loan at 4.29%.
First interest-only payment was done on May 5.
So, on June 5 second interest-only payment is done.
Interest she paid on May 5 is,
First Interest = [tex]\frac{6000*4.29}{12*100}[/tex]
= [tex]\frac{25740}{1200}[/tex]
= $21.45
Thus, the balance after the first interest = $6000 + $21.45
= $6021.45
Interest she paid on June 5 is,
Second Interest = [tex]\frac{6021.45*4.29}{12*100}[/tex]
= [tex]\frac{25832.02}{1200}[/tex]
= $21.53
Thus, the amount of that interest-only payment is $21.53.

Solution
- The shirt shrank a little. This implies that when you take the ratio of the dimensions of the shrunk shirt, and that of the original shirt.
- This would mean that the scale factor (the result from the above ratio), would be less than 1. But it would not be that much less than 1.

Answer:
cos(25) = sin(65)
sin(25) = cos(65)
tan(45) = tan(45)
Explanation:
To know which are the true statements, we will use the following identities
sin(θ) = cos(90 - θ)
cos(θ) = sin(90 - θ)
Therefore,
sin(25) = cos(90 - 25)
sin(25) = cos(65)
cos(25) = sin(90 - 25)
cos(25) = sin(65)
Additionally, tan(45) is equal to itself, so
tan(45) = tan(45)
Therefore, the true statements are
cos(25) = sin(65)
sin(25) = cos(65)
tan(45) = tan(45)
