Answer:
There are 90 ways.
Step-by-step explanation:
We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.
Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.
Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.
10*9 multiplying
= 90.
Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
The total number of different combinations for the president and vice-president roles from a group of ten people is 90, based on the concept of permutation in combinatorics. After choosing one president among the ten people, there would be nine people left to be chosen for the vice-president position.
Explanation:This problem is about choosing two different roles (president and vice president) from a group of 10 people, with each person having a chance to occupy each role. This falls under the domain of combinatorics, a branch of mathematics dealing with combinations of objects belonging to a finite set following certain rules. We would need to use the concept of permutation in this instance. Permutations refer to the arrangement of items in a specific order.
Since all the 10 people could potentially be president, there are ten choices for the president. And after choosing a president, we would have left nine people. Among these, anyone could be vice-president, giving us nine choices for the vice-president. Hence, the total number of ways is equal to the product of the number of choices for the president and the vice-president, which is 10×9= 90.
Thus, there are 90 different combinations for the president and vice- president roles.

Determine the range of the function f(x)=x^2-2/2 when the domain is {0, 2}.
HELP
The range of function is { -1, 1 }
Solution:
Given that, the function is:
[tex]f(x) = \frac{x^2-2}{2}[/tex]
Domain is {0, 2 }
We have to find the range of function
The domain refers to the set of possible input values
The range is the set of possible output values

Substitute x = 0 in given function
[tex]f(0) = \frac{0-2}{2}\\\\f(0) = \frac{-2}{2}\\\\f(0) = -1[/tex]
Substitute x = 2 in given function
[tex]f(2) = \frac{2^2-2}{2}\\\\f(2) = \frac{4-2}{2}\\\\f(2) = \frac{2}{2} = 1[/tex]

Which descriptions can describe more than one triangle? Select two options.
side lengths of 6 ft, 8 ft, and 10 ft
angle measurements of 35, 35, and 110°
angle measurements of 30°, 40, and 50°
angle measurements of 40°, 60°, and 80°
side lengths of 4 cm, 6 cm, and 9 cm
Answer:
angle measurements of 35, 35, and 110°
angle measurements of 40°, 60°, and 80°
Step-by-step explanation:
we know that
The length sides of a triangle must satisfy the Triangle Inequality Theorem and the sum of their interior angles must be equal to 180 degrees
Remember that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
That means, I can have more than one triangle with the same internal angles
so
Verify each description
case 1) side lengths of 6 ft, 8 ft, and 10 ft
Remember that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the triangle inequality theorem
1) 6+8 > 10 ---> is true
2) 6+10 > 8 ---> is true
3) 8+10 > 6 ---> is true
therefore
The description describe only one triangle
case 2) angle measurements of 35, 35, and 110°
The sum of the interior angles is equal to 180 degrees
therefore
The description can describe more than one triangle, by similar triangles
case 3) angle measurements of 30°, 40, and 50°
The sum of the interior angles is not 180 degrees
therefore
The description is not a triangle
case 4) angle measurements of 40°, 60°, and 80°
The sum of the interior angles is equal to 180 degrees
therefore
The description can describe more than one triangle, by similar triangles
case 5) side lengths of 4 cm, 6 cm, and 9 cm
Remember that
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side
so
Applying the triangle inequality theorem
1) 4+6 > 9 ---> is true
2) 4+9 > 6 ---> is true
3) 6+9 > 4 ---> is true
therefore
The description describe only one triangle

Write as a product of two polynomials.
x(y–5)–y(5–y)
Final answer:
The expression x(y-5) - y(5-y) can be rearranged and factored into (y - 5)(x + y), which is the expression written as a product of two polynomials.
Explanation:
To write the expression x(y-5) - y(5-y) as a product of two polynomials, we first distribute the variables across each term:
x(y-5) = xy - 5x
-y(5-y) = -5y + y²
Now, combining like terms:
xy - 5x - 5y + y²
This expression can't be factored as is, since it cannot be represented by the product of two simpler polynomials with real coefficients. However, we can rearrange the terms:
(xy - 5y) + (y² - 5x) = y(x - 5) + y(y - 5)
Here we can see a common factor of (y-5):
(y - 5)(x + y)
This is the expression written as a product of two polynomials.
Change 6 1/8 into an improper fraction.

Therefore, your improper fraction is 49/8.
The improper fraction equivalent of 6 1/8 is 49/8.
Given that a mixed fraction 6 1/8, we need to convert it into improper fraction,
To change a mixed number like 6 1/8 into an improper fraction, you need to convert the whole number and the fraction into a single fraction.
Step 1: Multiply the whole number by the denominator of the fraction.
6 x 8 = 48
Step 2: Add the product from Step 1 to the numerator of the fraction.
48 + 1 = 49
Step 3: Write the result from Step 2 over the original denominator.

Boyle's Law says that the volume of a gas varies inversely with the pressure. When the volume of a certain gas is 5 L, the pressure is 304 kPa (kilopascals). What is the volume when the pressure is 80 kPa ?
Answer:
19 L
Step-by-step explanation:
Given that the volume (V) varies inversely with the pressure (P) then the equation relating them is
V = [tex]\frac{k}{P}[/tex] ← k is the constant of variation
To find k use the condition V = 5 when P = 304
k = VP = 5 × 304 = 1520
V = [tex]\frac{1520}{P}[/tex] ← equation of variation
When P = 80, then
V = [tex]\frac{1520}{80}[/tex] = 19 L

The slope of the line below is 2. Use the coordinates of the labeled point to
find a point-slope equation of the line. (1,9)
O A. y-9 = 2(x - 1)
O B. y+9 = -2(x + 1)
O C. y+ 9 = 2(x+1)
O D. y-9=-2(x - 1)
Answer:
Step-by-step explanation:
y - y1 = m(x - x1)
(1,9)...x1 = 1 and y1 = 9
slope(m) = 2
now we sub
y - 9 = 2(x - 1) <===
The point-slope equation of the line with slope 2 that passes through the point (1, 9) is y - 9 = 2(x - 1).
Explanation:To find the point-slope form equation of a line with a given slope and a point, use the formula y - y1 = m(x - x1),
where (x1, y1) is the point on the line and m is the slope.
In this case, the slope is given as 2 and the point is (1,9).
Substituting these values into the point-slope form formula yields the equation y - 9 = 2(x - 1), which represents the linear relationship between x and y corresponding to the described line.
a village having a population of 4000, requires 150 litres of water per head per day. it has a tank measuring 20m x 15m x 6m. for how many days will the water of this tank last?
The water will last for 3 days
Solution:
Given that, village having a population of 4000, requires 150 litres of water per head per day
Let us first find the volume of tank
The tank measuring 20m x 15m x 6m
Length = 20 m
Breadth = 15 m
Height = 6 m
[tex]volume\ of\ tank = length \times breadth \times height[/tex]
[tex]Volume\ of\ tank = 20 \times 15 \times 6 = 1800[/tex]
Thus volume of tank is 1800 cubic meter
From given,
Water required per person per day = 150 liters
Therefore, water required for 4000 people per day is:
[tex]\rightarrow 4000 \times 150 = 600000 \text{ liters }[/tex]
Convert to meters
[tex]600000 \text{ liters } = 600000 \times \frac{1}{1000}\ m^3\\\\600000 \text{ liters } = 600\ m^3[/tex]
How many days will the water of this tank last?
[tex]\text{Number of days water will last } = \frac{\text{volume of tank}}{\text{total water required per day}}[/tex]
[tex]\text{Number of days water will last } = \frac{1800}{600} = 3[/tex]
Thus the water will last for 3 days
