Lets get started :)
The Volume formula of a Cylinder is
V =
r²h
(r = radius, h = height)
The radius given is 8 and the height is 4, We can plug in the known values
V =
(8)²(4)
=
256
=
256 units³ (You can leave the answer in this form)
≈
804.2 units³ (approximately)
Units
³ because it is a volume (3D shape)
Volume=s*s*s=1*1*1=1cm3cross section area=s*s=1*1=1cm2surface area=6*Surface Area=(1cm2)6=6cm2
Answer:
a. 20x > 10x + 80
b. •20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Step-by-step explanation:
10x + 80 = number of seashells Pilar has.
20x = number of seashells Marisol has.
answer for a: 20x > 10x + 80
answer for b: 20x > 10x + 80
• Subtract 10x from both sides: 20x -10x > 10x + 80 - 10x
• Simplify: 10x > 80
• Divide both sides by 10: 10x/10 > 80/10
• Simplify: x > 8
Answer: The correct answer should be 7.6128
If you do the problem correctly, you will get an answer of 7.6128. This is because there are 4 decimals places in the numbers that are being multiplied. This means that there will be 4 decimal places in the answer. If you have her work, we can find the mistake. It is probably that she counted the wrong number of places.
Answer:
The coefficient of variable term y is -1
Step-by-step explanation:
We have an expression given in the question that is:
6 - y + 3
We have to find the coefficient of the variable term.
In mathematics, variable can be defined as any term which is to be measured. For example in the given expression, y is the variable because its value is unknown yet and it has to be measured.
Coefficients are the number the multiply the variable
For example
In 2x, x is the variable and 2 is the coefficient.
Now in the given expression, we have
6 - y + 3
or
6 + (-1)(y) + 3
So considering (-1)(y), the variable is y while its coefficent is -1
