Terri is sawing wood into shorter pieces of equal lengths. Some original pieces are 30 inches long, some are 48 inches long, and some are 72 inches. She cannot waste any wood. What is the longest possible length of the shorter pieces that Terri saws?

Answer:

X+Y-3

Step-by-step explanation:

I don’t know what X/Y is, but “three less than” means you need to subtract 3 from the sum of X+Y

28 is a counterexample of the conditional "If a number is divisible by seven, then it is odd." since 28 is divisible by 7 but is even.

Odd numbers are a type of integer that are not divisible by 2. They are characterized by having a remainder of 1 when divided by 2. Odd numbers can be represented by the formula 2n+1, where n is any integer.

Odd numbers continue indefinitely in both directions on the number line.

Odd numbers play an important role in many areas of mathematics, including number theory, algebra, and geometry. For example, they are often used in proving mathematical theorems and in constructing mathematical models.

Odd numbers also have some practical applications. For example, they can be used to represent the number of items in a group, such as the number of people in a room or the number of apples in a basket. Odd numbers are also used in some programming languages to control the flow of code and make decisions based on conditions.

Therefore,  one of the rectangle braces measures 137.3 cm to the closest tenth of a centimetre.

A rectangle is a rectangle with four perpendicularly in the Euclidean plane. It is also known as an apparent equal-sided rectangle or an equiangular parallelogram. Another option for the trapezoid is a straight angle. A square has four edges that are the same length. Quadrilaterals that are rectangular have four identical sides and 4 90° edges. As a result, it is sometimes referred to as a "rectangular trapezoid".

Here,

the vertical brace serves as the hypotenuse of a right triangle, which has the bookcase's sides serving as its legs. The diagonal brace's length can be determined as follows:

length of diagonal brace

=> √(length² + height²)

When we enter the numbers from the problem, we obtain:

length of diagonal brace

= >√(115² + 76²) ≈ 137.3 cm

Using the closest tenth of a centimetre as a guide, we obtain:

diagonal brace length: 137.3 centimetres

As a result, one of the braces measures 137.3 cm to the closest tenth of a centimetre.

Check the picture below.

so hmmm let's find the length of the slanted side, namely the hypotenuse of the triangle with sides of 9 and 7(half of 14).

\(\begin{array}{llll} \textit{using the pythagorean theorem} \\\\ c^2=a^2+o^2\implies c=\sqrt{a^2 + o^2} \end{array} \qquad \begin{cases} c=hypotenuse\\ a=\stackrel{adjacent}{9}\\ o=\stackrel{opposite}{7} \end{cases} \\\\\\ c=\sqrt{ 9^2 + 7^2}\implies c=\sqrt{ 81 + 49 } \implies c=\sqrt{ 130 }\)

Answer:

$44

Step-by-step explanation:

Hello!

It said that 7 cameras cost $308, right?

If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:

7x = 308.

If 7x = 308, it would be

308/7 =

44.

So, $44 is the answer.

Answer: c  

Step-by-step explanation: the equation asks for the divison of the two equal libruims and u subtract the numeriator by the scound stance

The equation to show the perimeter of the rectangle is P = 2(2w + 5)

From the question, we have the following parameters that can be used in our computation:

Length = 5 more than the width

Also, we have

Perimeter = 58

This means that

P = 2(w + 5 + w)

P = 2(2w + 5)

In (a), we have

P = 2(2w + 5)

This gives

2(2w + 5) = 58

So, we have

2w + 5 = 29

2w = 24

w = 12

Next, we have

l = 12 + 5

l = 17

Lastly, we have

Area = 17 * 12

Area = 204

Answer:

y= -x²-4x+2

Step-by-step explanation:

write in vertex form

a(x-h)²+k

in our case h = -2 and k= 6

y=a(x+2)²+6

now we just need to solve for a. we know that when x= 1 y = -3. plug these values in and solve for a

-3= a(1+2)²+6

-9=9a

a= -1

thus the formula is -(x+2)²+6

generally, teachers want things in standard form, so expand the exponent and simplify.

-(x²+4x+4)+6

y= -x²-4x+2

Answer:

\(y = -x^2 - 4x + 2\)

Step-by-step explanation:

The equation of a parabola in vertex form is:

\(y = a(x - h)^2 + k\)

where (h, k) is the vertex of the parabola.

In this case, the vertex is (-2, 6), so h = -2 and k = 6.

We also know that the parabola passes through the point (1, -3).

Plugging these values into the equation, we get:

\(-3 = a(1 - (-2))^2 + 6\)

\(-3 = a(3)^2 + 6\)

-9 = 9a

a = -1

Substituting a = -1 into the equation for a parabola in vertex form, we get the equation of the parabola:

\(y = -1(x + 2)^2 + 6\)

This equation can also be written as:

\(y = -x^2 - 4x -4+6\\y=x^2-4x+2\)

Answer:

The inverse is  5±sqrt(x+25)

Step-by-step explanation:

y = x^2 - 10x

To find the inverse, exchange x and y and solve for y

x = y^2 -10y

Complete the square

x+25 = y^2 -10y +25

x+25 = (y-5)^2

Take the square root of each side

±sqrt(x+25) = y-5

Add 5 to each side

5±sqrt(x+25) = y

The inverse is  5±sqrt(x+25)

Answer:

\(y=\pm\sqrt{x+25}+5\)

Step-by-step explanation:

Given function:

\(y=x^2-10x\)

Rearrange to make \(x\) the subject.

First, complete the square by adding 25 to both sides and factoring:

\(y+25=x^2-10x+25\)

\(y+25=(x-5)^2\)

Square root both sides:

\(\pm\sqrt{y+25}=x-5\)

Add 5 to both sides:

\(x=\pm\sqrt{y+25}+5\)

Finally, swap \(x\) and \(y\) (since the inverse of a function is its reflection in the line \(y = x\))

\(y=\pm\sqrt{x+25}+5\)

Answer:

The surface area of a rectangular prism is calculated by adding the areas of all six faces. The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh, where l is the length, w is the width and h is the height.

In this case, the length is 7 cm, the width is 3 and three-fifths cm (or 3.6 cm), and the height is 2 and two-fifths cm (or 2.4 cm). Plugging these values into the formula gives us a surface area of 2(7) (3.6) + 2(7) (2.4) + 2(3.6) (2.4), which simplifies to 50.4 + 33.6 + 17.28, or 101.28 square centimeters.

So, the surface area of this rectangular prism is 101.28 square centimeters.

Received message. The surface area of a rectangular prism is calculated by adding the areas of all six faces.

Answer:

\( x = \dfrac{1}{10} \)

Step-by-step explanation:

\( 4^{\frac{3}{4}} \times 2^x = 16^{\frac{2}{5}} \)

\( (2^2)^{\frac{3}{4}} \times 2^x = (2^4)^{\frac{2}{5}} \)

\( 2^{2 \times \frac{3}{4}} \times 2^x = 2^{4 \times \frac{2}{5}} \)

\( 2^{\frac{3}{2}} \times 2^x = 2^{\frac{8}{5}} \)

\( 2^{\frac{3}{2} + x} = 2^{\frac{8}{5}} \)

\( x + \dfrac{3}{2} = \dfrac{8}{5} \)

\( 10x + 15 = 16 \)

The number of listeners is given from the total number of listeners and

the ratio of the listeners between the two stations.

Required:

Given:

The daily listening audience of the AM station = 4 × The audience of the FM sister station

The number of people that listen to the two stations = 105,000

Required:

The number of listeners of the FM station

Solution:

The ratio of the listeners is 1:4

Let x represent the number of listeners of the FM sister station, we have;

The number of listeners of AM radio station = 4·x

Which gives;

4·x + x = 105,000

5·x = 105,000

\(x = \dfrac{105,000}{5} = \mathbf{21,000}\)

Answer:

5 ≤ L ≤ 35

Step-by-step explanation:

Let w represent the width of the rectangle.

The perimeter (P) of the rectangle is given by:

P = 2w + 2L

Where L is the length of the rectangle.

We know that w = 30 cm and that the perimeter is between 100 and 160 cm. We can now set up our compound inequality:

100 ≤ 2(30) + 2L ≤ 160

100 ≤ 90 + 2L ≤ 160

10 ≤ 2L ≤ 70

We can now divide both sides by 2 to solve for L:

5 ≤ L ≤ 35

Therefore, the compound inequality that represents the graph of a rectangle with a width of 30 centimeters and a perimeter of 100 centimeters to 160 centimeters is:  5 ≤ L ≤ 35
