How many of theese objects are likely to have an area less than 1 acre?

Answers

Answer 1
Answer:
It's impossible to tell.  You haven't told us anything whatsoever
about the objects ... not even WHAT they are.  We don't know
whether they're cells, football fields, continents, planets, or galaxies.

Is there any chance that maybe, just maybe, the list of objects is
right there with the part of the question that you copied and posted,
but you felt that we could answer the question without knowing what
they are, so you didn't bother posting the list ?

Rosa has 4 1/2 pounds of pizza dough. She uses 3/4 of a pound for one pizza. How many pizzas could be made from Rosa's dough?

Answers

Amount of pizza dough that Rosa has = 4 1/2 pounds
                                                               = 9/2 pounds
Amount of dough required by Rosa to make 1 pizza = 3/4 pounds
Then
The number of pizza that can be made with 9/2 pounds of dough = 1/(3/4) * (9/2)
                                                                                                         = (4/3) * (9/2)
                                                                                                         = 2 * 3
                                                                                                         = 6
So Rosa can make 6 pizzas with the amount of dough she has.I hope the procedure is clear enough for you to understand.Glad to have helped you.

Step-by-step explanation:

What is the volume of the cylinder below? A. 72π units³

B. 36π units³

C. 45π units³

D. 90π units³

Answers

Answer:


Step-by-step explanation:

According to the diagram, the radius of this cyl. is 3 and the height is 4 (not 5).  The formula for the volume of a cylinder is:

V = pi*r^2*h.

Here, that volume is V = pi*3^2*4, or 36 pi cubic units.  That's Answer B.


The volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.

Further explanation:

The formula for the volume of the cylinder can be expressed as,

\boxed{{\text{Volume}} = \pi {r^2}h}

Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.

Given:

The radius of the cylinder is {\text{3 units}} and the height of the cylinder is {\text{4 units}} and the slant height is 5{\text{ units}}

The options of the volume are given as follows.

A. {\text{72}}\pi {\text{uni}}{{\text{t}}^3}

B. 36\pi {\text{uni}}{{\text{t}}^3}

C. 45\pi {\text{uni}}{{\text{t}}^3}

D. 90\pi {\text{uni}}{{\text{t}}^3}

Explanation:

The volume of the right cylinder can be obtained as follows,

\begin{aligned}{\text{Volume}} &= \pi {r^2}h\n&= \pi* {\left( 3 \right)^2} * 4\n&= \pi * 9 * 4\n&= 36\pi\n\end{aligned}

The volume of the cylinder is 36\pi {\text{ unit}}{{\text{s}}^3}.

Option A is not correct.

Option B is correct.

Option C is not correct.

Option D is not correct.

Hence, the volume of the right cylinder is \boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.

If 2x^2 + 6x = 36, what are the possible values of x ?

Answers

The possible values of x for 2\cdot x^(2)+6\cdot x = 36 are x_(1) = 3 and x_(2) = -6.

The expression2\cdot x^(2)+6\cdot x = 36 is equivalent to the expression2\cdot x^(2)+6\cdot x -36 = 0, which represents a second orderpolynomial, that is, a polynomial of the form:

y = a\cdot x^(2)+b\cdot x + c(1)

Where a,\,b,\,c are coefficients.

The possible values of x represents all possible roots of x, which are found analytically by the quadratic formula:

x = \frac{-b\pm \sqrt{b^(2)-4\cdot a\cdot c}}{2\cdot a}(2)

If we know that a = 2, b = 6 and c = -36, then all possible values of x are, respectively:

x_(1) = 3, x_(2) = -6

The possible values of x for 2\cdot x^(2)+6\cdot x = 36 are x_(1) = 3 and x_(2) = -6.
