Step-by-step explanation:

550 is the closest

A square can be divided into two right-angled triangles with one line, but it can't be divided into two obtuse triangles because none of the angles in a square is more than 90 degrees.

No, it is not possible for Kateri to divide the square into two obtuse triangles by drawing just one line. An obtuse triangle is a triangle that has an angle greater than 90 degrees. However, a square is made up of four 90-degree angles. Therefore, when a square is divided into two triangles with one line, the maximum degrees any angle in resulting triangles would get is 90, hence they would be right-angled triangles and not obtuse triangles.

Answer:

62.4 hours

Step-by-step explanation:

For P:

Number of hours off on 10 hours of working=0.4

Number of hours on 2080 hours of working=2080/10*0.4

=83.2 hours

For S:  

Number of hours off on 100 hours of working=7

Number of hours on 2080 hours of working=2080/100*7

=145.6 hours

The difference between the vacation hours of P and S is of 62.4 hours. S will get more hours of vacation.  

the difference in vacation hours between the two friends is 62.4 vacation hours.

For company P:

We know that 10 working hours give 0.4 vacation hours. So, to find vacation hours for 2080 hours, we can set up the following proportion:

[tex]\frac{10}{0.4} = \frac{2080}{vacation\ hours\ of 2080\ working\ hours}[/tex]

Solving this we get:

[tex]vacation\ hours\ of\ 2080\ working\ hours = \frac{0.4 \times 2080}{10} = 0.04 \times 2080 = 83.2\ days[/tex]

Now for company S:

We know that 100  working hours give 7 vacation hours. So, to find vacation hours for 2080 hours, we can set up the following proportion:

[tex]\frac{100}{7} = \frac{2080}{vacation\ hours\ of 2080\ working\ hours}[/tex]

Solving this we get:

[tex]vacation\ hours\ of\ 2080\ working\ hours = \frac{7 \times 2080}{100} = 0.07 \times 2080 = 145.6\ days[/tex]

Finally, find the difference in vacation hours:

[tex]Difference = 145.6 - 83.2 = 62.4\ vacation\ hours[/tex]

Therefore, the difference in vacation hours between the two friends is 62.4 vacation hours.

Using trigonometry, Claire is approximately 19.42 feet away from Marisa, given their angles of elevation and the hoop's height.

Using trigonometry, we can find the distance between Claire and Marisa:

[tex]\[ \text{Let } h \text{ be the height of the basketball hoop.} \][/tex]

[tex]\[ \text{Distance}_{\text{Claire}} = \frac{h}{\tan(35°)} \][/tex]

[tex]\[ \text{Distance}_{\text{Marisa}} = \frac{h}{\tan(25°)} \][/tex]

[tex]\[ \text{Distance}_{\text{Claire-Marisa}} = \text{Distance}_{\text{Claire}} - \text{Distance}_{\text{Marisa}} \][/tex]

[tex]\[ \text{Distance}_{\text{Claire-Marisa}} = \frac{h}{\tan(35°)} - \frac{h}{\tan(25°)} \][/tex]

[tex]\[ \text{Distance}_{\text{Claire-Marisa}} = h \times \left( \frac{1}{\tan(35°)} - \frac{1}{\tan(25°)} \right) \][/tex]

Given [tex]\( h = 10 \)[/tex] feet:

[tex]\[ \text{Distance}_{\text{Claire-Marisa}} = 10 \times \left( \frac{1}{\tan(35°)} - \frac{1}{\tan(25°)} \right) \][/tex]

[tex]\[ \text{Distance}_{\text{Claire-Marisa}} \approx 19.42 \text{ feet} \][/tex]

So, Claire and Marisa are standing approximately 19.42 feet apart.

Final answer:

The expression 27x^2z/-3x^2z^6 simplifies to -9/z^5, so the simplified exponent on the variable z is -5.

Explanation:

When simplifying the expression 27x^2z/-3x^2z^6, we divide the coefficients and apply the laws of exponents. This means we divide 27 by -3 and subtract the exponents of like terms with variables of the same base.

27/-3 equals -9, and for the variables we subtract the exponents, for x^2 we have x^2/x^2 which simplifies to x^0 and for z we have z^1/z^6, simplifying to z^(1-6) which is z^-5. However, because negative exponents denote division by that variable to the positive exponent, z^-5 represents 1/z^5.

The final simplified expression is -9/z^5. Thus, the exponent on the variable z when the expression 27x^2z/-3x^2z^6 is completely simplified is -5.

Answer:

Volume of rectangular prism = [tex]\frac{65}{4}=16\frac{1}{4}=16.25[/tex]

Step-by-step explanation:

Given :   A rectangular prism has a length of [tex]1\frac{1}{4}[/tex]  centimeters, a width of 4 centimeters, and a height of  [tex]3\frac{1}{4}[/tex] centimeters.

We have to find the volume of prism.

We know,

Volume of rectangular prism = length ×  width × height

Given : Length = [tex]1\frac{1}{4}[/tex] centimeters =  [tex]\frac{5}{4}[/tex]

Width = 4 centimeters, and

height = [tex]3\frac{1}{4}[/tex]  centimeters = [tex]\frac{13}{4}[/tex]

Thus, Volume of rectangular prism = [tex]\frac{5}{4}\times 4\times \frac{13}{4}[/tex]

Simplify, we have,

Volume of rectangular prism = [tex]\frac{65}{4}=16\frac{1}{4}=16.25[/tex]

The volume of the given rectangular prism is 0.143184 cubic meters (m³).

The formula of the volume of a rectangular prism is:

Volume = Length × Width × Height

Given the dimensions:

Length = 114 cm

Width = 4 cm

Height = 314 cm

First, multiply the length and the width:

Length × Width = 114 cm × 4 cm = 456 cm²

Next, multiply this result by the height:

456 cm² × 314 cm = 143,184 cm³

Therefore, the volume of the rectangular prism is:

143,184 cm³

Now, to convert this into cubic meters (m³), note that 1 m³ = 1,000,000 cm³:

Volume in m³ = 143,184 cm³ ÷ 1,000,000 = 0.143184 m³

So, the volume of the prism is 0.143184 m³.

To memorize your timetables, you can use mnemonic techniques, break down the tables into smaller chunks, and practice regularly.

Multiplication tables, also known as timetables, can be challenging to memorize. However, there are several strategies that you can use to make the process easier. One effective method is to create mnemonics, which are memory aids that help you associate numbers with images or phrases. For example, you can associate the number 9 with the shape of a cat's tail, and whenever you see the number 9 in a multiplication problem, you can visualize a cat's tail to help you remember the answer.

Another useful strategy is to break down the tables into smaller, more manageable chunks. Start by memorizing the tables for numbers 0-5, and once you feel comfortable with them, move on to the tables for numbers 6-10. By tackling smaller chunks, you can avoid overwhelming yourself and improve your retention.

Finally, practice regularly and consistently. The more you review the timetables, the more familiar they will become. Consider using online resources, flashcards, or interactive games to make the practice sessions more engaging and enjoyable. Over time, with practice and perseverance, you will gradually memorize your timetables.

Answer:

B) The slope is negative 1/2 and the y-intercept is (0, 3).

Step-by-step explanation:

First we rewrite the equation so we can easily find the slope and y-intercept.  We do this by isolating the y-term:

2x+4y = 12

We want to subtract 2x from each side:

2x+4y-2x = 12-2x

4y = 12-2x

4y = -2x+12

Now we divide both sides by 4 (everything on both sides gets divided!):

4y/4 = -2x/4 + 12/4

y = -2/4x + 3

y = -1/2x + 3

The slope is -1/2 and the y-intercept is 3 (the point (0, 3)).

Her graph shows the y-intercept at (0, 3); this part is correct.

The graph also shows we go down one and over two between points; this is a slope of -1/2, which is correct.
