Answer:
11 kg
Explanation:
Given weight in kg ∝ d² where d is the distance of the object from the center of the earth
We can write this as an equatio
w = (k/d²) where is a constant
On the surface of the earth, d = 600, w = 80 so we get
80 = k/600² ==> k = 600² ( 80) = 600 x 600 x 80 (1)
At 1000 km altitude, the actual distance of the astronaut from the center of the earth is 1000 + 600 - 1600 km
So we get another equation w' = k/1600²
were w' is the weight of the astronaut at an altitude of 1000km
Using the value of k from (1) we get
w' = (600 x 600 x 80)/(1600 x 1600) = 11.25kg = 11 correct to the nearest kg

Which of the following is a characteristic of all minerals?
a. Contains silicon
b. Inorganic
c. Liquid
d. Man-made
Answer is b. Inorganic
The correct option is b. One main characteristic of all minerals is that they are inorganic.
What is a mineral?
A mineral is a term used to describe a naturally occurring material that has its own set of unique chemical and physical properties. These properties can vary, such as hardness, colour, acidity level, etc. Examples of minerals includes, gold, copper, crude, etc, all of these materials are not man made, they are naturally occuring.
What does inorganic mean?The term inorganic describes any material that is not made up of living matter. In other words, they are liveless substances. Hence, minerals are classified as inorganic materials due to having this very nature.

In the figures above, lines l and m are parallel and BD bisects ABC. What is the value of x?
Answer:
54 degrees
Explanation:
Plot point X on the left of point A on line l. Lines l and m are parallel, and segment AB is the transversal. Angles BAX and ABC are alternate interior angles, so they are congruent (same angle measures). Since segment BD bisects angle ABC, angles ABD and DBC are congruent. Therefore angle ABD is 108/2 = 54 degrees. In the diagram, we can also see that angle DAB is 180-108 = 72 degrees. Since interior angles of a triangle add up to 180, angle ADB is 180-72-54 = 54 degrees.

The number of additional tea bags that are needed to make each additional cup of tea is: B. one.
What is a linear function?A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
What is a slope?A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
x and y are the points.m is the slope or rate of change.c is the intercept.Comparing the given equation with the standard form of the equation of a linear function, we have:
t ⇒ y, n ⇒ x;
t = n + 2 ≡ y = mx + c
Therefore, we can logically deduce that the slope (m) is equal to one (1).

~A certain rectangular prism has a height of h inches, a width that is 3 inches less than its height, and a length that is 4 inches more than its height. Ifthe area ofthe base of the prism is 60 square inches, what is the volume of the prism, in cubic inches?
Answer:
Volume = 480 cubic inches
Explanation:
We have the following relationships to work with
width w = h -3
length l = h + 4
area of base of prism a = l x w = 60 (1)
area of base in terms of h = (h-3)(h+4) =h² -3h + 4h -12 (2)
Setting (1) = (2) gives
h² + h -12 =60
h² + h -72 = 0
Factoring the LHS we get
(h+9)(h-8) = 0
The solutions for h are
h + 9 = 0 ==> h = -9
h - 8 = 0 ==> h = 8
Since h cannot be negative, h = 8 inches
Volume = base area x h = 60 x 8 = 480 cubic inches
Note
We do not have to calculate length and width separately, but if so,
w = 8 -3 = 5
l = 8 + 4 = 12
