If we divide a number by zero, it will result in infinity, which is not a number.
That's why we can't divide by 0.
So the answer is undefined.

Rafael, Denise, and Philippe are doing a project together. They decide to base the project on a book that is 540 pages long. Rafael plans to read a certain number of pages. Denise will read Three-fourths of the number of pages Rafael reads, and Philippe will read One-half of the number of pages that Rafael reads. How many pages will Rafael read?
180
240
300
432
Answer:
Rafael will read 240 pages.
Step-by-step explanation:
Let's start by setting up the unknowns:
x = # of Rafael's pages
x/2 = # of Philippe's pages
(3/4)x = # of Denise's pages
Set these all equal to 540:
(x) + (x / 2) + (3/4(x)) = 540
Let's multiply both sides by 4 to make this easier.
4x + 2x + 3x = 2160
9x = 2160
x = 240
x was the # of Rafael's pages, so Rafael will read 240 pages. This means that Philippe will read 120 pages (one-half of Rafael), and Denise will read 180 pages (three-fourths of Rafael). Adding these all up will get you 540 pages, so it checks out.
Hope this helps!

Answer: x = -.63, -2.37
Step-by-step explanation:
x=−32±3–√2
x=−0.633975
x=−2.36603
Find the Solution for
2x2+6x+3=0
using the Quadratic Formula where
a = 2, b = 6, and c = 3
x=−b±b2−4ac/√2a
x=−6±62−4(2)(3)/√2(2)
x=−6±36−24/√4
x=−6±12−−√4
The discriminant b2−4ac>0
so, there are two real roots.
Simplify the Radical:
x=−6±23–√4
x=−64±23–√4
Simplify fractions and/or signs:
x=−32±3–√2
which becomes
x=−0.633975

The lateral surface area of a 3D figure is the surface area of the solid, excluding the bases. For a cylinder, the bases are the two circles on top and bottom. The formula to find the LSA of a cylinder is 2πrh, where r = radius of the circle and h = height.
» Application
We are asked to find the lateral surface area of the cylinder given the radius as 4.2 cm and the height as 10.9 cm.

number (i.e 22,23) can be obtained by adding 11 to its previous number. Ex. 23 = 12 + 11
And the odd number(i.e the first, third etc) can be obtained by subtracting 11 from its next number or by adding 1 to the previous odd number(i.e 12 = 11 + 1) Henceforth, the next number will be 12 + 1 = 13The number after 13 will be 13 + 11 = 24The number after 24 will be 13 + 1 = 14If you found this useful, please mark it as the BRAINLIEST.XD

pls pls help i cant get this
Answer:
See below
Step-by-step explanation:
Find the radius
circumference = pi d
16 pi = pi d
then d = 16 radius = 8 units
area of the TWO ends = TWO * pi (8)^2 =128 pi units^2
Find the height
hypotenuse = 10 one leg = radius = 8
10^2 = 8^2 + h^2
h = 6 units
lateral area = circumference * height
= 16 pi * 6 = 96 pi units^2
total area is then 128 pi + 96 pi = 224 pi units^2

Step-by-step explanation:
Finding compound interest :
A = (110,000)(1 + 0.025)⁶A = (110,000)(1.025)⁶A = (110,000)(1.15969342)A = $127,566.28A

The measure of the angle m∠CBD that forms an adjacent angle is 35 degrees.
What are adjacent angles?Adjacent angles are angles that have common side and vertex.
Therefore, the common vertex is at point B.
m∠CBD = m∠ABD - m∠ABC
Therefore,
m∠ABD = 75 degrees
m∠ABC = 40 degrees
Hence,
m∠CBD = 75 - 40
m∠CBD = 35 degrees

Which angle is congruent to ZBAD?
O ZBCD
ZCAB
D
O 2DBC
O ZACD
ZCAB angle is congruent to ZBAD
The triangles ΔDAB and CAB are congruent and measure of ∠BAD = measure of ∠CAB
What are Congruent Triangles?Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape
The three sides are equal (SSS: side, side, side)
Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)
Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)
Given data ,
Let the first triangle be represented as ΔCAB
Let the second triangle be represented as ΔDAB
Now , the measure of BD = measure of BC ( given )
The measure of side AB = measure of side AB ( reflexive property )
And , the measure of ∠BAD = measure of ∠CAB
So , Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)
Therefore , the triangles are congruent by SAS theorem
Hence , the triangles are congruent

Pierre asks Sherry a question involving the theoretical probability of a compound event in which you flip a coin and draw a marble from a bag of marble. The bag of marbles contains 3 white marbles, 8 green marbles, and 9 black marbles. Sherry’s answer, which is correct, is __ 12/40. What was Pierre’s question?
Pierre's question : What is the probablity of flipping a head and picking a white or black marble at the same time?
The probability of flipping a head is 50%, or 1/2
The probably of randomly picking a white or black marble is (3+9)/(3+9+8) = 12/20.
So, the probability of they happening simultaneously is 1/2 x 12/20 = 12/40.
