on a map, two cities are 5 1/2 inches apart. the map uses a scale of 2 inches =75 miles
what is the actual distance between the two cities?
Answer:
187.5 miles
Step-by-step explanation:
We can use the rationing method to solve for this problem.
2 inches on map = 75 miles actual distance
1 inch on map = (75 ÷ 2) = 37.5 miles actual distance
5.5 inches on map = (37.5 × 5) = 187.5 miles actual distance

find the perimeter or circumference and area of each figure if each unit on the graph measure 1 centimeter. round answers to the nearest tenets, if necessary
The circumference of the circle = 17.8 units
The area of the circle = 25.1 square unit
Given,
the points are A(2,3) and B(4,1)
Formula to get the circumference of a circle = 2πr
Where r = radius of the circle
Radius of the given circle = Distance between the points A(2, 3) and
B(4, 1)
r = √(2 - 4)² + (3 -1)²
r = √(-2)² + (2)²
r = √4+4
r = √8
r = √2(4)
r = 2√2
Therefore the circumference is = 2π(2√2)
= 17.77
≈ 17.8 units
Area of the circle = πr²
= π(2√2)²
= 8π
= 25.13
≈ 25.1 square unit
Hence we get the circumference and area of the circle as 17.8 units and 25.1 square unit respectively.

mr keon spent 5/8 of his salary of
2 416.00 on food,rent,clothes and transport how mush money did he spend
The salary Mr. Keon spent 1510 on food, rent, clothes, and transport.
The term "linear function" in mathematics applies to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields.
If y is the amount of money Mr. Keon spent on food and clothes and x is Mr. Keon's salary.
Then the linear function for the relation between x and y is:
y = ( 5/8) × (x)
y = (5/8)x
The salary of Mr. Keon is 2416.
Now, Mr. Keon spent 5/8 of his salary on food, rent, clothes, and transport.
Let x be the money she spent.
Then,
x = 5/8 of Mr. Keon's salary
x = ( 5/8 ) × 2416
x = ( 2416 × 5 ) / 8
x = 12080 / 8
x = 1510

Step-by-step explanation:
trapezium means especially
AD || BC
AC = BC tells us that ABC is an isoceles triangle (both legs are identically long, which makes also their angles with their baseline AB equal).
therefore, A1 = B = 80°.
and because the sum of all angles in a triangle is always 180°, we get
180 = 80 + 80 + C1
C1 = 20°
(e)(1)
because of the law of a line intersecting parallel lines with the same angles, and AC is intersecting the parallel lines AD and BC, we know that
C1 = A2 = 20°
(e)(2)
because also the sum of all angles around a single point on one side of a line is 180°, we know D1 + D2 = 180°.
we also know that D2 is an angle in an equilateral triangle (that means all 3 sides are equally long, and therefore all 3 angles are equal too = 180/3 = 60°) and therefore
D2 = 60°.
therefore, D1 = 180 - 60 = 120°.
so, for the triangle ACD we have
180 = A2 + D1 + C2 = 20 + 120 + C2
C2 = 40° = 2×20 = 2×C1
(f)(1)
a kite is a quadrilateral, and as such the sum of all angles is 360°.
again remember the symmetry of a kite, so the angles at H and at F must be equal.
H = F = x
so, we have
360 = 110 + 50 + H + F = 110 + 50 + 2x
200 = 2x
x = 100°
(f)(2)
after drawing EG we see that this line splits the kite into 2 equal (ahem, congruent) triangles due to the symmetry of a kite exactly along that line.
and that splits both angles E and G in half for each of the triangles.
again, the sum of all angles in a triangle is 180°, so
180 = 110/2 + 50/2 + x = 55 + 25 + x = 80 + x
x = 100°

The British imperial and American customary systems of measurement both use the inch as their standard unit of length (symbolized as in or ′′). It is equivalent to 1/36 of a yard or 1/ 12 of a foot. The term inch, which is often used to translate comparable units in other measurement systems and is derived from the Roman uncia ("twelfth"), is generally considered to refer to the breadth of the human thumb.
Since the international yard was adopted in the 1950s and 1960s, standards for the precise length of an inch have varied, but the inch is now based on the metric system and is defined as precisely 25.4 mm.

A plastic boulder was launched from a second-floor window, using a catapult. The function below represents the height of the
plastic boulder from the ground, h(t), in feet, over time, t, in seconds.
h(t) = -2x² + 2x + 40
How many seconds did it take for the plastic boulder to hit the ground?
Answer:
5 seconds
Step-by-step explanation:
Given the height function h(t) = -2x² + 2x + 40, you want the positive value of t such that h(t) = 0.
SolutionThe given function can be factored as ...
h(t) = -2(x -5)(x +4)
This will be zero when the factors are zero:
x -5 = 0 ⇒ x = 5
x +4 = 0 ⇒ x = -4
The positive value of t for which the height is zero is t = 5.
It took 5 seconds for the plastic boulder to hit the ground.

There are several methods available for factoring the equation. One is to factor out the leading coefficient, then factor the remaining quadratic.
-2(x² -x -20)
To factor this, you're looking for factor pairs of -20 that have a sum of -1.

The length of a shadow of a building is 10 m. The distance from the top of the building to the tip of the shadow is 26 m. Find the height of the building
Answer:
The height of the building is 24m
Step-by-step explanation:
This can be solved using the Pythagorean theorem
which states that the three sides of a right triangle are related by the equation
[tex]c^2 = a^{2} + b^{2}[/tex] (see figure)
where c is the hypotenuse and a, b are the other two sides
Here we have c = the distance from the top of the building to the tip of the shadow = 26m
One side, the length of the shadow ie b = 10 m
So we have
[tex]26^2 = a^2 + 10^2[/tex] where a is the height of the building
Switch sides to get
[tex]a^2 + 10^2 = 26^2[/tex]
[tex]a^2 + 100 = 676[/tex]
Subtract 100 from both sides
[tex]a^2 = 676 - 100 = 576[/tex]
[tex]a = \sqrt{576}[/tex]
a = 24
The height of the building is 24m
