The company Sea Esta has ten members on its board of directors. In how many different ways can it
elect a president, vice-president, secretary and treasurer?
there are 5040 ways by using permutations to select a president, vice-president, secretary and treasurer from 10 members on its board of directors.
Total members = 10
number of positions = 4
Now, we will use permutations.
So, we get that:
Number of ways = 10 × 9 × 8 × 7
Number of ways = 90 × 56
Number of ways = 5040 ways
Therefore, we get that, there are 5040 ways by using permutations to select a president, vice-president, secretary and treasurer from 10 members on its board of directors.

John who is 5 ft tall is standing 20 feet away from a tree, and you measure the angle of elevation to be 38∘. How tall is the tree? Find your answer to the nearest tenth
Answer:
The tree is 20.6 ft tall.
Step-by-step explanation:
Please check the attached graph.
From the diagram, it is clear that John is 5 ft tall is standing 20 feet away from a tree, making an angle of elevation to be 38⁰.
The diagram makes a right-angled triangle.
Given the angle = Ф = 38⁰Adjacent = a = 5 ftOpposite = b = 20 ftHypotenuse = Tree length = c ?Pythagorean Theorem:
For a right-angled triangle, with sides 'a' and 'b', the hypotenuse 'c' is defined as:
[tex]\:c=\sqrt{a^2+b^2}[/tex]
substituting a=5, b=20
[tex]c=\sqrt{5^2+20^2}[/tex]
[tex]c=5\sqrt{17}[/tex]
[tex]c=20.6[/tex] ft
Thus, the tree is 20.6 ft tall.

What expression is equivalent to 5 x 18
Answer: 10x36
Step-by-step explanation: 5x18 multiply by 2 and 2. 5 times 2 is 10 and 18 times 2 is 36.
Given the equation 5x - 7 = 18. What is
the first step in solving this equation?
Adding 7 to both sides.
Subtracting 5 from both sides.
Subtracting 7 from both sides.
Dividing by 5 on both sides.
Answer:
The answer is adding 7 to both sides.
Step-by-step explanation:
5x-7=18
+7 +7
5x= 25
x=5
Answer:
Answer: Adding 7 to both sides.
Step-by-step explanation:
You always do the "inverse" of the number without the variable next to it and either "add" or "subtract" it to the other side.
Ex: 7x - 3 = 18
In this case, you would add the 3 to the other side.
7x - 3 = 18
+ 3 +3
7x = 21
7x 7x
x = 3

We have proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷ .
In the given question
we have to prove that
(2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷
For proving we will solve the LHS and RHS separately and then equate them .
First Solving LHS
we have
=(2*10²)*(3*10⁵)
=(2*3)*(10²*10⁵)
=6*10²⁺⁵ ...( because aⁿ.aˣ = aⁿ⁺ˣ )
=6*10⁷ ...(i)
Now solving RHS
we have
=3.5*10⁷+2.5*10⁷
taking 10⁷ common , we get
=(3.5+2.5)*10⁷
Adding the terms in the bracket we get
=6*10⁷ ...(ii)
As we can see that from equation (i) and (ii) we have LHS=RHS
Hence proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷
Therefore , Proved that (2*10²)*(3*10⁵) = 3.5*10⁷+2.5*10⁷ .

In parallelogram HIJK, the measure of angle H is 45 degrees. 1.Find the measure of J and explain how you know
Answer:
45°
Step-by-step explanation:
A parallelogram is a polygon with 4 sides and 4 angles (that is a quadrilateral).
For a parallelogram ABCD, Opposite sides and opposite angles are equal (i.e. BC = AD and ∠A = ∠C).
Consecutive angles are supplementary that is ∠A + ∠B = 180°.
The diagonals of a parallelogram bisect each other also separating the parallelogram into two congruent triangles.
In parallelogram HIJK, ∠H and ∠J are opposite angles. hence:
∠H = ∠J (opposite angles of a parallelogram are equal)
∠J = 45°

In excess of 8% of secondary school seniors in the United States utilized the medication something like once in the course of their life, and almost 4% involved the medication in the previous year, as per the University of Michigan's Monitoring the Future Survey. In spite of the fact that by the 1980s LSD use had extraordinarily declined, it made a resurgence during the 1990s, basically among teens. An overview led by Monitoring the Future Study discovered that 13.6 percent of 1997's secondary school seniors had tried different things with LSD no less than once contrasted with just 7.2 percent in 1986.

If 6 1/2 is the lesser number in an inequality, which statement is true about the other number in the inequality? A. The other number is located to the left of 6 1/2 on the horizontal number line. B. The other number is located above 6 1/2 on the vertical number line. C. On the horizontal number line, 6 1/2 is located to the right of the other number. D. on The vertical number line, 6 1/2 is located above the other number.
Answer:
B. The other number is located above 6 1/2 on the vertical number line.
Step-by-step explanation:
Given
[tex]Lesser\ Number = 6\frac{1}{2}[/tex]
Let the other number be n such that:
[tex]n > 6\frac{1}{2}[/tex]
On a horizontal number line; number increases from left to right.
This means that n will be at the right and [tex]6\frac{1}{2}[/tex] will be at the left
Or
On a vertical number line; number increases from bottom to top.
This means that n will be at the top and [tex]6\frac{1}{2}[/tex] will be at the bottom

If segment RS has endpoint R(-4,-6) and midpoint M(3,-4) what is point S
Based on the calculations using the midpoint rule, the value of point S is equal to (10, 12).
What is a line segment?A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.
How to determine the other endpoint?In order to determine the midpoint of a line segment with two (2) endpoints, we would add each point together and divide by two (2).
Midpoint on x-coordinate is given by:
xm = (x₁ + x₂)/2
3 = (-4 + x₂)/2
Cross-multiplying, we have:
6 = -4 + x₂
x₂ = 6 + 4
x₂ of S = 10.
Midpoint on y-coordinate is given by:
ym = (y₁ + y₂)/2
3 = (-6 + y₂)/2
Cross-multiplying, we have:
6 = -6 + y₂
y₂ = 6 + 6
y₂ of S = 12.
Therefore, point S is equal to (10, 12).

The force of
gravity on the moon is only 16.6% the force
of gravity on Earth. For each item listed in the
table below, fill in what its weight would be on
The complete table is given below:
ITEM W(E) W(M)
Apple 150 g 25 g
Hammer 1.5 lbs 0.25 lbs
Person 180 lbs 30 lbs
Blue whale 200 tons 33.3 tons
Here, we are given that the force of gravity on the moon is only 16.6% the force of gravity on Earth.
This means that for an object of mass 'm' -
F(M) = 16.6% of F(E)
This means that a person would weigh six times less on the moon than they do on Earth
W(moon) = [W(earth)]/6
Thus, we can complete the table as follows-
ITEM W(E) W(M)
Apple 150 g 1/6 x 150 = 25 g
Hammer 1.5 lbs 1/6 x 1.5 = 0.25 lbs
Person 180 lbs 1/6 x 180 = 30 lbs
Blue whale 200 tons 1/6 x 200 = 33.3 tons
