I saw the image that should have been posted with this word problem.
The rolls of wrapping paper is cylindrical in shape.
Roll A : length = 30 inches ; diameter = 3 inches
Roll B : length = 24 inches ; diameter = unknown
Lateral surface area = 2 π r h
Lateral Surface area of Roll A = Lateral Surface area of Roll B
2 * 3.14 * 1.5in * 30in = 2 * 3.14 * r * 24 in
282.60 in² = 150.72 in * r
282.60 in² / 150.72 in = r
1.875 in = r
diameter is 2 times the radius = 1.875 in * 2 = 3.75 inches
The diameter of Roll B is 3.75 inches.
Answer:
-2x + 5
Step-by-step explanation:
Considering the definition of an equation and the way to solve it, the total cost of the shoes is 0.20×(x-15).
<h3>Definition of equation</h3>
An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
<h3>Total cost in this case</h3>
Being "x" the price of the shoes, and knowing that:
- you apply a discount of $15 first → x -15
- you apply a discount of 20% through a second discount (
- (applied on the first discount already made) → 20%×(x-15) → 0.20×(x-15)
the equation in this case is:
<u><em>Total cost= 0.20×(x-15)</em></u>
Finally, the total cost of the shoes is 0.20×(x-15).

Answer:
C. The largest exponent value of the a terms is equal to the value of the exponent on the binomial. The exponent values are then equal to 0 throughout the expansion.
Step-by-step explanation:
i think tho but this makes sense
Thank you for posting your question here at brainly. If point B on the pre-image lies at (3, 4), the are the coordinates of B'' on the final is (5, -6). Below is the solutions, I hope the answer helps.
rx-axis ◦ T2,2 (3,4)
<span>= rx-axis ( T2,2 (3,4) ) </span>
<span>= rx-axis ( 5,6 ) </span>
= (5, -6)
