Answers
60 feet² is the area of rectangle.
What is rectangle?
A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. As a result, it is sometimes referred to as an equiangular quadrilateral. Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel.The four sides of a laptop are equal in length and have opposite sides that are parallel to one another.length = 5 feet
wide = 12 feet
area of rectangle = length × width
= 5 × 12

how many 725ml is in liters?
Answers
ANSWER
There are 0.725L in 725mL
EXPLANATION
Given that
The volume in mL is 725mL
Follow the steps below
Recall, that 1mL is equivalent to 0.001L
Let x represents the volume in Liters
[tex]\begin{gathered} \text{ 1mL }\rightarrow\text{ 0.001L} \\ \text{ 725mL }\rightarrow\text{ xL} \\ \text{ cross multiply} \\ \text{ 1mL }\times\text{ xL = 725mL }\times\text{ 0.001L} \\ \text{ isolate xL} \\ \text{ xL = }\frac{725\cancel{mL}\times\text{ 0.001L}}{1\cancel{mL}} \\ \text{ xL = 725 }\times\text{ 0.001} \\ \text{ x = 0.725L} \end{gathered}[/tex]Therefore, there are 0.725L in 725mL
If f(x) = x^4 − x^3 + x^2 and g(x) = −x^2, where x ≠ 0, what is (f ⁄g)(x)?
Answers
The correct answer is
[tex](\frac{f}{g})(x)=-x^2+x-1[/tex]To solve this, first let's write the division:
[tex]f(x)=x^4-x^3+x^2,g(x)=-x^2\Rightarrow(\frac{f}{g})(x)=\frac{x^4-x^3+x^2}{-x^2}[/tex]Now we can factor out a x^2 on the top and the bottom of the expression:
[tex](\frac{f}{g})(x)=\frac{x^4-x^3+x^2}{-x^2}\Rightarrow(\frac{f}{g})(x)=\frac{x^2(x^2-x+1)}{x^2(-1)}[/tex]Now we can cancel out and divide by (-1), or the same thing, multiply by (-1):
[tex](\frac{f}{g})(x)=\frac{x^2(x^2-x+1)}{x^2(-1)}=-(x^2-x+1)=-x^2+x-1[/tex]Then the answer is (f/g)(x) = -x^2 + x - 1. That's the third option

Calculate perimeter, height and base.
Answers
The values are given as;
Perimeter = 26cm
Height = 4cm
Base = 9cm
How to determine the valueThe formula for determining the area of a rectangle is expressed as;
Area = lw
Where;
l is the length of the rectanglew is the width of the rectangleNow, substitute the values into the formula, we have;
36 = (x +7)(x + 2)
Now, expand the bracket
36 = x^2 + 2x + 7x + 14
collect like terms
36 = x^2 + 9x + 14
Make into quadratic equation
x^2 + 9x + 14 -36 = 0
x^2 + 9x - 22 = 0
Factorize the equation
x^2 + 11x - 2x - 22 = 0
Factorize further
x(x + 11) - 2( x + 11) = 0
Then, x - 2 = 0, x = 2
or x + 11 = 0
x = -11
Height = x + 2 = 4cm
Base = x + 7 = 9cm
The formula for perimeter is expressed as;
Perimeter = 2( l +w )
Perimeter = 2( 4 + 9)
Perimeter = 2(13)
Perimeter = 26 cm
Hence, the values are 26cm, 4cm and 9cm respectively.

3) Triangle ABC is dilated by a scale factor of 4 to form triangle A'B'C'. Wha-are the coordinates of vertex A'? Make sure that you enter the coordinatesin the form of (x, y) below. *Your answer
Answers
Answer
A' (-8, 4)
Explanation
When a figure, that is on the coordinates system is dilated (that is, enlarged or reduced) with respect to the origin, the new coordinates of its edges is simply a product of its old coordinates and the scale factor.
For this question, the coordinates of A is (-2, 1) and the dilation of the triangle ABC is by a scale factor of 4.
So, the new coordinates of A will be calculated thus
A (x, y) = A' (x × scale factor, y × scale factor)
A (-2, 1) = A' (-2 × 4, 1 × 4) = A' (-8, 4)

The probability that a randomly selected bottle has a volume greater than v mL is 0.366. Find the value of v.
Answers
A probability distribution that is symmetric about the mean is the normal distribution, sometimes referred to as the Gaussian distribution. It demonstrates that data that are close to the mean occur more frequently than data that are far from the mean. The normal distribution appears as a "bell curve" on a graph.
Explain the normal distribution with an example?
One straightforward example of anything that has a normal distribution pattern is height: The majority of people are normal height, although there are nearly equal numbers of people who are taller or shorter than average and a very small (but roughly comparable) number who are either extraordinarily tall or extremely short.
The four properties of a normal distribution are visible here. The mean, median, and mode are all equal in normal distributions, which are symmetric, unimodal, and asymptotically distributed.
Add the mean to the x value in step 1. Subtract the difference from the standard deviation in step two. A value of 1380 has a z-score of 1.53. Thus, 1380 is 1.53 standard deviations away from the distribution's mean.

so
B=L*W=(6.5*5)=32.5 in2
P=2(L+W)=2(6.5+5)=23 in
H=7.5 in
therefore
SA=2(32.5)+23(7.5)

An equation is a formula that describes the equality between two expressions, by connecting them with the equals sign '='.
Let the cost of lollipops be x
The cost of gumballs be y
and cost of chocolates be z
We are given that the gumballs cost 5 cents more than the chocolates
mathematically this can be written as

Similarly,
The lollipops cost twice as much as the chocolates
mathematically this can be written as,
[tex]x=2z[/tex]
Now finally we purchase 3 gumballs, 2 lollipops and 7 chocolates
The equation can be given as,
[tex]3x+2y+7z=2.11[/tex]
Substituting the values of x and y in this equation we get,
[tex]6z+2(z+0.05)+7z=2.11\\6z+2z+0.1+7z=2.11\\15z=2.01\\z=0.134[/tex]
The cost of chocolates is $0.134
The cost of gumballs is $0.184
And the cost of lollipops is $0.268

A rectangular carport has area 150 square feet. The height of the carport is five feet less than twice its length. Find the height and the length of the carport.
Answers
We are given that the area of a rectangle is 150 square feet. If "h" is the height and "l" is the length then the area is given by:
[tex]hl=150[/tex]We are also given that the height is 5 feet less than twice its length, this can be written mathematically as:
[tex]h=2l-5[/tex]Now we can replace the value of "h" in the equation for the area:
[tex](2l-5)l=150[/tex]Now we use the distributive property:
[tex]2l^2-5l=150[/tex]Now we have a quadratic equation that can be written as:
[tex]2l^2-5l-150=0[/tex]We can factor this equation to determine the values of "l". We multiply and divide by 2:
[tex]\frac{4l^2-5(2l)-300}{2}=0[/tex]Factoring in the numerator:
[tex]\frac{(2l-20)(2l+15)}{2}=0[/tex]Now we take common factor in the first parenthesis in the numerator:
[tex]\frac{2(l-10)(2l+15)}{2}=0[/tex]Simplifying:
[tex](l-10)(2l+15)=0[/tex]Now we set each factor to zero:
[tex]\begin{gathered} l_1-10=0 \\ l_1=10 \\ 2l_2+15=0 \\ l_2=-\frac{15}{2} \end{gathered}[/tex]We take the positive value, therefore, the length of the rectangle is 10 feet. Now we replace this value in the equation for the height.
[tex]h=2(10)-5[/tex]Solving we get:
