The area of the base of a rectangular prism is 18 cm2. The height of the prism is 9 1 2 cm. What is the volume of the prism?

Answers

The volume of the rectangular prism with a base area of 18 cm2 and height of 9 1/2 cm is calculated to be 171 cm3, using the formula Volume = area of base x height.

The volume of a rectangular prism is calculated by multiplying the area of the base by the height of the prism. In this case, the area of the base is given as 18 cm2, and the height is 9 1/2 cm, which can also be written as 9.5 cm for easier multiplication.

To find the volume, we use the formula: Volume = area of base * height. Substituting the known values, we get:

Volume = 18 cm2 * 9.5 cm

Volume = 171 cm3

Therefore, the volume of the rectangular prism is 171 cm3.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that Yasmine needs to create invitations for the party. She has ¾ of an hour to make the invitations. It will takes her 1/12 of an hour to make each card.

Since Yasmine takes 1/12 hour create number of cards = 1

Yasmine takes 1 hour to create number of cards = 1 x 12/1 = 12

Yasmine takes 3/4 hour to create number of cards = 12 x 3/4 = 9

Therefore, It is found that Yasmine can create 9 cards.

 a=-1/4 , so -1/4 is slope
b=5, so b is y-intercept 

We can convert to slope-intercept form, and whatever number is the coefficient of x will be the slope.
We subtract by 1/4x on both sides and get y = -1/4x + 5. So, the slope is -1/4.

Expand. Your answer should be a polynomial in standard form. (4−7y)(7+4y)

Answers

You have to distribute the (4-7y) to (7+4y). After distributing, you get the answer: -28y^2-33y+28
Final answer:

To expand (4−7y)(7+4y), apply the FOIL method to get the expanded form: 28 + 16y - 49y - 28y². Combine like terms to get the standard form: -28y² - 33y + 28.

Explanation:

To expand the given expression (4−7y)(7+4y), we need to apply the distributive property (also known as the FOIL method in this case, which stands for First, Outer, Inner, Last):

First: Multiply the first terms in each binomial: 4 × 7 = 28.Outer: Multiply the outer terms: 4 × 4y = 16y.Inner: Multiply the inner terms: -7y × 7 = -49y.Last: Multiply the last terms: -7y × 4y = -28y².

Combine the middle terms (16y and -49y) and arrange the polynomial in standard form, which is ordering terms from highest to lowest degree:

Expanded form: 28 + 16y - 49y - 28y²

Combine like terms: 28 - 33y - 28y²

Standard form: -28y² - 33y + 28

what the answer subtitution of x=6+y and ×-4y=21

Answers

x= 6 + y
x - 4y= 21

The first equation is already solved for x. Take the value of x (6 + y) and substitute it for the x value in the second equation.

x - 4y= 21
(6 + y) - 4y= 21
combine like terms
6 - 3y= 21
subtract 6 from both sides
-3y= 15
divide both sides by -3
y= -5

Substitute the -5 for y in the equation to solve for x

x - 4y= 21
x - 4(-5)= 21
x + 20= 21
subtract 20 from both sides
x= 1

CHECK:
x= 1
y= -5

x= 6 + y

Natalia is drawing a rectangle. She wants the width to be at least 10 inches and the perimeter to be no more than 72 inches.
A.) write a system of inequalities that can be used to solve this problem.
B.) give a possible length and width for the rectangle.
C.) give a length and width that cannot be used for the rectangle.

Answers

A) Let's write equations with the given information. We will use L for length and W for width. Also, 2L+2W will represent the perimeter.

W >= 10
2L + 2W <= 72

B) To give a possible length and width, we don't need to solve the system. We can plug use numbers that will satisfy the equations above.

One possible solution would be W = 12 and L = 10. In this case, the width is greater than 10, and the perimeter is 44 which is less than 72.

C) One answer that would NOT work is W = 5 and L = 10 because width is less than 10.

Another example would be W = 20 and L = 18 because the perimeter would be greater than 72.





Final answer:

Natalia's problem involves creating a system of inequalities with limitations on width and perimeter. Possible rectangle dimensions follow this system, such as a width of 10 inches and a length of 26 inches. Dimensions that don't comply, like a width of 9 inches or a width of 10 inches with a length of 27 inches, are not feasible.

Explanation:

To address Natalia's rectangle problem, we need to create a system of inequalities based on her requirements for width and perimeter. Let's denote the width as w and the length as l. The inequalities should look like this:

w ≥ 10 (The width must be at least 10 inches)2l + 2w ≤ 72 (The perimeter must be no more than 72 inches)

Possible dimensions for Natalia's rectangle that satisfy these inequalities could be a width of 10 inches and a length of 26 inches. In this case, the perimeter would be 2(10) + 2(26) = 72 inches, which is the maximum allowed.

Impossible dimensions would include a width of 9 inches, as this is less than the minimum required width, or a width of 10 inches with a length of 27 inches, which would make the perimeter 2(10) + 2(27) = 74 inches, exceeding the maximum permitted perimeter.

Is it 2.20? Because if the square root is 2.23 then you’d find the value of the nearest hundredth?

Answers

When you round a number, you look at the size of the number before it. In this case, you are rounding the hundredths place, so you will look at the size of the thousandths place. 
The square root of 5 is approximately 2.236
You want to find the hundredths place, so you'll need to look at the thousandths place. 
The thousandths place is 6, which is more than 5, so you will round 2.236 up to 2.24

The square root of 5 to the nearest hundredth is 2.24

The GCD of two different prime numbers is 1, and the LCM is the product of the two primes.

GCD(a,b) is the Greatest Common Divisor, which is the largest positive integer that divides both numbers without a remainder. For two different prime numbers a and b, their GCD will be 1 because there are no common factors other than 1. LCM(a,b) is the Least Common Multiple, which is the smallest multiple that is divisible by both numbers. For prime numbers a and b, their LCM will be the product of the two primes.

Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5). Show your work.

Answers

we know that

The triangle is right-angled with the legs DE (horizontal) and DF (vertical).

see the attached figure

Hence
the circumcenter is the mid-point of the hypotenuse EF,
point E (8,3)    point F(1,-5)
Fin the mid-point

Xm=(8+1)/2----------> Xm=4.5
Ym=(-5+3)/2----------> Xm=-1
the mid-point is (4.5,-1)

the answer is
the circumcenter is the point (4.5,-1)

ANSWER  

The circumcenter of triangle DEF has coordinates [tex](4.5,-1)[/tex]

EXPLANATION

The circumcenter of triangle DEF is the point where all the three perpendicular bisectors of the three sides of the triangle intersect.

Let us find the perpendicular bisector of any two sides, because the third one will also meet these two perpendicular bisectors at the same point.

The perpendicular bisector of ED passes through the midpoint of the line connecting D(1,3) and E(8,3).

We must therefore find the midpoint to obtain,

[tex]N=(\frac{1+8}{2},\frac{3+3}{2})=(4.5,3)[/tex]

The slope of ED is

[tex]n=\frac{3-3}{8-1}=0[/tex].

The slope of the perpendicular bisector is the negative reciprocal of the slope of ED

[tex]slope=-\frac{1}{0}[/tex] which undefined.

The equation of a line that has an undefined slope is given by

[tex]x=x_1[/tex].

Therefore the equation of the perpendicular bisector of ED is [tex]x=4.5--(1)[/tex]

We must also find the equation of the perpendicular bisector of DF.

The midpoint of D(1,3) and F(1,-5) is [tex]M=(\frac{1+1}{2}, \frac{3+-5}{2})=(1,-1)[/tex]

The slope of DF is

[tex]m=\frac{-5-3}{1-1} =\frac{-8}{0}[/tex] this is an undefined slope but let us keep it like this for now.

The perpendicular bisector will have a slope that is the negative reciprocal of this undefined slope

[tex]slope=-\frac{1}{\frac{-8}{0}}= \frac{0}{8}=0[/tex]. This means that the slope is parallel to the x-axis.

The equation of lines that are parallel to the x-axis is given by the formula,

[tex]y=y_1[/tex].

Therefore the equation of the perpendicular bisector is [tex]y=-1--(2)[/tex].

The perpendicular bisectors will intersect at, [tex](4.5,-1)[/tex]

Hence the circumcenter is [tex](4.5,-1)[/tex]
