Classify each number by indicating in which set or sets it belongs 8 and 0.25
The number 8 belongs to the sets of natural numbers, integers, rational numbers, and real numbers, while the number 0.25 only belongs to the sets of rational and real numbers.
Explanation:In mathematics, numbers can belong to various sets such as the natural numbers, integers, rational numbers, real numbers, etc. In this case, the number 8 belongs to all these sets because it is a whole number without fractions or decimals. Therefore, it is a natural number, integer, rational number and real number.
On the contrary, 0.25 is a decimal which belongs to the sets of rational numbers and real numbers. It does not belong to the sets of natural numbers or integers because it is not a whole number.

What two numbers multiply to 12 and add to negative 4?
The two numbers that multiply to 12 and add to negative 4 are -6 and 2.
To find the two numbers, we need to solve the system of equations:
1. xy = 12 (Equation 1)
2. x + y = -4 (Equation 2)
From Equation 2, we can express y in terms of x:
y = -4 - x (Equation 3)
Now, we substitute Equation 3 into Equation 1:
[tex]\( x(-4 - x) = 12 \)\\ \( -4x - x^2 = 12 \)\\ \( x^2 + 4x - 12 = 0 \)[/tex]
We can factor this quadratic equation:
[tex]\( (x + 6)(x - 2) = 0 \)[/tex]
Setting each factor equal to zero gives us two possible solutions for x:
[tex]\( x + 6 = 0 \) or \( x - 2 = 0 \)[/tex]
So, [tex]\( x = -6 \) or \( x = 2 \)[/tex].
Using Equation 3 to find the corresponding y values:
If ( x = -6 ), then ( y = -4 - (-6) = 2 ).
If ( x = 2 ), then ( y = -4 - 2 = -6 ).
Therefore, the two pairs of numbers that satisfy both conditions are (-6, 2) and (2, -6). Since the question asks for two numbers, and both pairs contain the same numbers, the answer is -6 and 2.

A cereal manufacturer decides to offer a new family-sized box based on the regular-sized box. They want the volume of the family-sized box to be three times the volume of the regular-sized box. However, they want the length of the family-sized box to be the same as the regular-sized box. If they decide to double the width to create the family-sized box, by what factor must they increase the height?
volume = l x w x h
to increase volume by 3 you would have 3*l*w*h
so 3*l*w*h= l*2*w* x *h ( x is the scale factor)
cancel out the l w and h on both sides
3 = 2x
Divide both sides by 2
x = 3/2 = 1.5
the height should increase by a factor of 1.5
Answer:
3/2 or 3 over 2

Which ordered pair can be removed so that resulting graph represent a function ?
The ordered pair which can be removed so that resulting graph represent a function is:
(1,3)
Step-by-step explanation:Function--
A function is a relation in which each of the element of first set is mapped to a single element of the other set.
i.e. no element is mapped to two elements i.e. there is a single image for each pre-image.
Here in the graph we have ordered pairs as:
(-5,-3) (-4,-4) (-2,2) (1,-2) (1,3) (2,1) (5,-4)
Hence, we see that element " 1 " is mapped two different elements
1 is mapped to -2 ( since, we have ordered pair (1,-2) )
and 1 is mapped to 3 ( since, we have ordered pair (1,3) )
If we remove the ordered pair (1,3) then the resulting graph will be a graph of a function.

which of the following statement are false? o vertical angles are congruent. o angles with measures between 0 and 90 are complementary. o straight angles are supplementary. o angles with measures between 90 and 180 are obtuse
Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure of one of these angles is 72 degrees, what are the measures of the other three angles. Explain your answer
they need to equal 180 degrees
180-72 = 108 degrees
Answer: 108, 108, and 72 degrees
Step-by-step explanation:
Angle A = 72
Angle B = Angle D
Angle C = 72 (Since it is congruent to Angle A)
Angle D = Angle B
Since Angle A and C are congruent, so are angles B and D. Now you would have to subtract 72 from 180.
180 - 72 = 108
Angle A = 72
Angle B = 108
Angle C = 72
Angle D = 108

A circle has an area of 153.86 square inches. Using 3.14 for pi, find the radius and circumference of the circle. Round your answer to the nearest hundredth when necessary.
To determine the radius and circumference of a circle with an area of 153.86 square inches, one must first divide the area by 3.14 to solve for r², then take the square root to find the radius, and finally use the radius to calculate the circumference. The radius is approximately 7.00 inches, and the circumference is approximately 43.96 inches.
Explanation:To find the radius and circumference of a circle with an area of 153.86 square inches, we first use the formula for the area of a circle, which is A = πr². Given that A is 153.86 and π is approximately 3.14, we can rearrange the formula to solve for the radius (r) as follows:
Divide the area by π: r² = A / π = 153.86 / 3.14.Take the square root of the result to find the radius: r = √(r²).Use the radius to calculate the circumference using the formula C = 2πr.Performing the calculations, we get:
r² = 153.86 / 3.14 = 48.99r = √(48.99) ≈ 7.00 inches (rounded to the nearest hundredth)C = 2 * 3.14 * 7.00 ≈ 43.96 inches (rounded to the nearest hundredth)Therefore, the radius of the circle is approximately 7.00 inches, and the circumference is approximately 43.96 inches.
To find the radius from the area of a circle, use the formula r = sqrt(A/pi), with A = 153.86 sq inches and pi as 3.14. Once the radius is determined, calculate the circumference with the formula C = 2*pi*r. Both values should respect the significant figures.
Explanation:The student is asking for help finding the radius and circumference of a circle given its area using 3.14 for pi. To find the radius, we start with the area formula for a circle, which is A = πr². Given the area A as 153.86 square inches, and using 3.14 for π, the radius r can be found by rearranging the formula to r = √(A/π). Plugging the numbers in, we get r = √(153.86/3.14), which we then calculate.
Once we have the radius, we can find the circumference C of the circle using the formula C = 2πr. Now that we know the radius, we plug the value into this formula to get the circumference.
Both radius and circumference should be calculated carefully, keeping in mind significant figures. The radius should then be used to calculate the circumference, which will be limited by the same degree of precision.

Convert 1.580 hectoliters to deciliters.
The value of 1.580 hectoliters in decilitres will be 1580.
What is unit conversion?Unit conversion is the process of changing a quantity's measurement between different units, usually using multiplicative conversion factors.
The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given that the fluids have a value of 1.580 hectoliters.
The value of hectoliters in deciliters will be converted as below,
1 hectoliters = 1000 deciliters
1.580 hectoliters = 1.580 x 1000 deciliters
1.580 hectoliters = 1580 deciliters
Therefore, the value of 1.580 hectoliters in decilitres will be 1580.
