Answer:
0<x<8.7
Step-by-step explanation:
for it to be a triangle, sum of two sides must be greater than the largest side.
so, if x is 8.4 or greater, it can't be a triangle since it is greater than the sum of 3.2 and 5.5
a side must be greater than 0
so , 0<x<8.7

Two rival companies began the same year. The equations below model the number of employees, y, at these companies x years after the companies began.
Company R: y = 3x + 24
Company T: y= 4x + 10
Company R stated, “We have 42 employees, the same number of employees as company T has this year.” Determine if company R’s claim is possible. Explain your reasoning.
Company T stated, “After 15 years, we will have the same year of employees as company R.” Determine if company T’s claim is possible. Explain your reasoning.
Answers
Answer:
Both the claims by the companies are not possible.
Step-by-step explanation:
Equations modeling number of employees 'y' after 'x' years of the start are,
For company R: y = 3x +24
For company T: y = 4x + 10
If Company R states that this year they have 42 employees,
42 = 3x + 24
3x = 42 - 24
x = [tex]\frac{18}{3}[/tex]
x = 6 years
So company has completed 6 years this year.
Now we put x = 6 years in the equation for company T.
y = (4×6) + 10
y = 24 + 10
y = 34
Which doesn't match with the number of employees of the company R.
Therefore, claim of company R is not possible.
Company T stated that after 15 years they will have the same number of employees as company R.
For company T : y = 4(15) + 10
y = 70 employees
For company R : y = 3(15) + 10
y = 45 + 10
y = 55 employees
Therefore, claim of the company T is also not possible.
Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:
Company R: y = 3x + 24
Company T: y= 4x + 10
If both companies has the same number of employees, then;
3x + 24 = 4x + 10
3x - 4x = 10 - 24
-x = -14
x = 14
Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.
Functions and values
Given the equations that model the number of employees y, at these companies x years after the companies began expressed as:
Company R: y = 3x + 24
Company T: y= 4x + 10
If both companies has the same number of employees, then;
3x + 24 = 4x + 10
3x - 4x = 10 - 24
-x = -14
x = 14
Since 14 ≠ 42 that company R claimed, hence the company does not have the same number of employees as company T has this year.
Since 14 ≠ 15 that company T also claimed, hence the company does not have the same number of employees as company T has this year.

What is the surface area of this cylinder?
Use a ~ 3.14 and round your answer to the nearest hundredth.
Answers
The surface area of the cylinder is [tex]\( 904.32 \, \text{cm}^2 \)[/tex]
The surface area (A) of a cylinder is given by the formula:
[tex]\[ A = 2\pi r^2 + 2\pi rh \][/tex]
where:
- [tex]\( r \)[/tex] is the radius of the base,
- [tex]\( h \)[/tex] is the height,
- [tex]\( \pi \)[/tex] is a constant approximately equal to 3.14.
Given the values:
- Radius [tex](\( r \))[/tex] = 8 cm
- Height [tex](\( h \))[/tex] = 10 cm
- [tex]\( \pi \)[/tex] = 3.14
Plug these values into the formula:
[tex]\[ A = 2 \times 3.14 \times (8)^2 + 2 \times 3.14 \times 8 \times 10 \][/tex]
[tex]\[ A = 2 \times 3.14 \times 64 + 2 \times 3.14 \times 80 \][/tex]
[tex]\[ A = 401.92 + 502.4 \][/tex]
[tex]\[ A = 904.32 \, \text{cm}^2 \][/tex]
Therefore, the surface area of the cylinder is [tex]\( 904.32 \, \text{cm}^2 \)[/tex].
The surface area of a cylinder is calculated using the formula A = 2πr² + 2πrh, combining the areas of the top and bottom circles and the side surface.
Explanation:To find the surface area of a cylinder, we need to add the areas of the two circular bases and the lateral surface area. The formula for the surface area of a cylinder is:
A = 2πr2 + 2πrh
where r is the radius of the circular base and h is the height of the cylinder. In this case, you can use a value of ~3.14 for π (pi) and round your answer to the nearest hundredth.
To calculate the surface area of a cylinder, you need to know the radius of the cylinder and its height. The formula for the surface area (A) of a cylinder is A = 2πr² + 2πrh, where r is the radius, and h is the height. This includes both the areas of the top and bottom circles (2πr²) and the area of the side surface (which is the circumference of the circle times the height, 2πrh). If the student provides the dimensions of the cylinder, use them to plug into this formula and calculate the surface area.

If a single marble is pulled out of the bag how many outcomes are in the sample
Answers
Answer:10
Step-by-step explanation:
The number of outcomes can vary based on whether the marbles are replaced or not after each draw.
The number of outcomes in the sample space when Maria draws a marble from the bag at random varies depending on the conditions:
If the marbles are replaced after each draw, the sample space remains constant with 7 marbles total (4 blue and 3 white), hence 7 outcomes.If the marble is not replaced, changing the composition to 3 blue and 3 white marbles on the second draw, the sample space then has 6 outcomes.The key factor affecting the number of outcomes is whether the marbles are replaced between draws.

the missing side is the same thing as the existing side. if you just take that triangle you see and flip it over, it will make a square. therefore, the length of the missing side is the same as the length of the existing side. sorry if this doesn't make sense haha
Step-by-step explanation:
A triangle has side lengths 1.5 cm, 2 cm, and 3 cm. Is this a right triangle? Explain.
Answers
Answer:
No
Step-by-step explanation:
To figure out whether a triangle is a right triangle using only the side lengths, you can use the Pythagorean theorem:
a^2 + b^2 = c^2
1.5^2 + 2^2 = 3^2
2.25 + 4 = 9
Since this equation isn't true, these numbers cannot be the side lengths of a right triangle.
After applying the Pythagorean theorem to the triangle with sides 1.5 cm, 2 cm, and 3 cm, it is determined that the triangle is not a right triangle because the squares of the shorter sides do not sum up to the square of the longest side.
Explanation:To determine if a triangle with sides measuring 1.5 cm, 2 cm, and 3 cm is a right triangle, we can apply the Pythagorean theorem. The theorem states that for any right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the other two sides (a and b). In mathematical terms, this is expressed as c² = a² + b².
Let's check if our triangle meets this condition:
Assume the longest side, 3 cm, is the hypotenuse (c).Square the lengths of the shorter sides: 1.5² + 2² = 2.25 + 4 = 6.25 cm².Square the length of the assumed hypotenuse: 3² = 9 cm².Since 6.25 cm² does not equal 9 cm², the sides do not satisfy the Pythagorean theorem, so the triangle is not a right triangle.
Which could be the cross section of a square pyramid? Select all that
apply.
Choose all that apply:
trapezoid
triangle
circle
pentagon
square
Answers
Final answer:
Cross sections of a square pyramid can include a trapezoid, a triangle, or a square. A circle or a pentagon are not possible shapes for these cross sections because they don't align with the pyramid's geometric structure.
Explanation:
The cross section of a square pyramid could be either a trapezoid, a triangle, or a square, depending on the plane's angle relative to the pyramid's base and sides. A circle or a pentagon cannot be cross sections of a square pyramid since they do not conform to the sides or base of a square pyramid.
A trapezoid cross-section can be obtained if the cutting plane is parallel to one base edge and intersects the other three edges of the pyramid. A triangle appears when the cutting plane passes through one vertex and cuts through the base, creating a cross section congruent to the faces of the pyramid. Lastly, a square section results when the cutting plane is parallel to the base and slices through the pyramid.

The rectangular area under the small swing set measures 9 feet by 12 feet and required 40 bags of sand to increase the depth by 3 inches.
How many bags of sand will the students need to cover the rectangular area under the large swing set if it is 1.5 times as long and 1.5 times as wide as the area under the small swing sets?
Answers
Answer:
90 bags of sand
Step-by-step explanation:
9 feet × 1.5 = 13.5
12 feet × 1.5 = 18
Large pit area= 13.5 × 18 = 243ft squared
The small pit area=9 × 12 = 108ft squared
243 / 108 = 2.25 times larger
This means the large pit needs 2.25 times more sand.
40 × 2.25 = 90 bags of sand

A fictional account offers benefits such as readers connecting emotionally with characters, like understanding George Washington's feelings, and provides immersive details on what experiencing historical events may have felt like, unlike nonfiction accounts which focus on factual precision.
A fictional account like the one in An American Plague by Jim Murphy offers two main benefits that a nonfictional account may not typically provide. First, it includes detailed characterization, which allows readers to connect with the characters on an emotional level. In this case, it's the portrayal of George Washington's feelings and his impatience as he left the city of Philadelphia. Second, a fictional account can offer vivid, imaginative details of what it was like to experience the event, thus bringing history to life in a way that purely factual retellings may not.
While nonfiction focuses on presenting the facts as accurately as possible, fiction can delve into the personal experiences and emotional journeys of historical figures, providing a different layer of understanding.

Write your answer as a whole number and remainder.
Answers
To divide 530 by 34, divide the quotient and the remainder. The whole number part of the quotient is 14 and the remainder is 54.
Explanation:To divide 530 by 34, we start by determining how many times 34 can fit into 530. We find that 34 can fit into 530 fourteen times. So, the whole number in the answer is 14. Now we calculate the remainder by subtracting 14 times 34 from 530. The remainder is 530 - (14 * 34) = 530 - 476 = 54.
Therefore, the answer to 530 divided by 34 is 14 with a remainder of 54.

An angle whose measure is 40° is in standard position. In which quadrant does the terminal side of the angle fall? Quadrant I Quadrant II Quadrant III Quadrant IV
Answers
Answer:
Quadrant 1
Step-by-step explanation:
The terminal side of the angle whose measure is 40° falls in quadrant I.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
To determine the quadrant in which the terminal side of an angle falls, we need to look at the direction in which the terminal side moves from the origin.
If the terminal side moves to the right of the origin, it is in quadrant I or IV; if it moves to the left of the origin, it is in quadrant II or III.
The angle whose measure is 40° starts on the positive x-axis and moves in a counterclockwise direction.
Since 40° is less than 90° the angle will move less than 90° counterclockwise from the x-axis.
The terminal side of the angle will fall in quadrant I, which is the quadrant that lies to the right of the positive x-axis and above the positive y-axis.
Hence, the terminal side of the angle whose measure is 40° falls in quadrant I.
