Step-by-step explanation:
The answer is a - (-b) = (-b) - a
for example if we take;
a = 4
b = 2
c = 2
and we replace;
4 - ( -2) = (-2) - 4
6 = -6
which is not true....
All the remaining are true....
even u can just use the values of abc and check if its true....

A map using a scale of 1 inch:5 miles shows a section of land with an area of 3.2 inches what is the actual area of the section of the land
Answer:
16 miles
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
Actual area = 3.2 x 5 = 16 miles
Find the volume of the rectangular prism.
The volume is cm?
8 cm
5 cm
9 cm
Answer:
360 cm
Step-by-step explanation:
volume= length x width x height
8*5*9=360 cm
Answer:
360cm
Step-by-step explanation:
All you have to do is multiply the numbers.
To break it up, you can first multiply 8 and 5.
8 x 5 = 40.
Now that you have 40, multiply that by 9.
40 x 9 = 360.
Apply the unit: cm
360cm is your answer.
A motorboat travels miles in hours going upstream. It travels miles going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current
Answer:
x = 49 mi/hr
y = 6 mi/hr
Step-by-step explanation:
A motorboat travels 258mi in 6 hours going upstream. It travels 330mi going downstream in same amount of time. What's the rate of the boat in still water and what is the rate of the current.
Let
x = the speed of the boat in still water.
y = the speed of the stream
The speed upstream is x - y
The speed downstream is x + y
Distance = rate × time
258 = (x - y)6 (1)
330 = (x + y)6 (2)
From (1)
x - y = 43 (3)
From (2)
x + y = 55 (4)
x - y = 43 (3)
x + y = 55 (4)
Add the equations to eliminate y
x + x = 43 + 55
2x = 98
x = 98/2
x = 49 mi/hr
Substitute x = 49 into (4)
x + y = 55 (4)
49 + y = 55
y = 55 - 49
y = 6 mi/hr

The perimeter of a triangular park is (16x + 3) feet. Two of the sides are 5x - 1 and 2x + 5. What is the missing length?
Answer:
9x - 1
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
the perimeter of a triangle = sum of the side lengths
missing length = perimeter - sum of the two sides
sum of the two sides = (5x -1) + (2x + 5) = 7x + 4
missing length = 16x + 3 - (7x + 4) = 9x-1

Applying the Pythagorean theorem, solve this triangle.
Answer:
The length of the hypotenuse is the square root of 169, which in turn is 13.
Step-by-step explanation:
Here we have a right triangle with leg lengths 12 m and 5 m. Because this is a right triangle, we can apply the Pythagorean Theorem to find the length of the hypotenuse.
The Theorem states that a^2 + b^2 = c^2. In this particular case,
(12 m)^2 + (5 m)^2 = c^2
which in turn becomes:
144 + 25 = 169. The length of the hypotenuse is the square root of 169, which in turn is 13.
PLS HELP ILL MAR BRAINLIST AND FOLLOW U
Answer:
Disagree
Step-by-step explanation:
The surface area of the given prism consists of the following parts;
1) The area of the top and bottom right triangles, A₁, and A₂, which are given as follows;
A₁ = A₂ = (1/2) × 5 × 12 = 30
2) The area of the left rectangle, A₃ = 5 × 8 = 40
3) The area of the rear rectangle, A₄ = 13 × 8 = 104
4) The area of the front rectangle, A₅ = 12 × 8 = 96
∴ A = A₁ + A₂ + A₃ + A₄ + A₅
A = 30 + 40 + 104 + 96 + 30 = 300
Jim B 65 + 65 + 104 + 96 + 40 = 370
The surface area of the triangular prism, A = 300 cm²
Jim-Bob's calculation contains two errors
1) 65 + 65 + 104 + 96 + 40 = 370 ≠ 270
2) The area surface area of the triangular prism = 300 cm² not 270 cm²
and therefore, disagree with his calculation.

In Marvel comics, T'Challa (aka The Black Panther) as the king of Wakanda
is estimated to be worth 90 trillion (9 x 1013) dollars. Tony Stark (aka Iron
Man) is only worth about 30 billion (3 x 1010) dollars. If Tony Stark could
somehow add a 10% increase in his wealth to his current worth each year
($30 billion, $63 billion, $99.3 billion, etc.), how many years would it take
to reach T'Challa? Round your answer to the nearest year.
If Tony Stark could somehow add a 10% increase in his wealth to his current worth each year then the number of years will be 84 to reach T'Challa.
What is an exponent?Exponential notation is a type of mathematical shorthand that allows us to express complex statements in a more concise manner. The basis of an exponent is a quantity or letter. It denotes that the base will rise to a specific level of strength. The base is X, and the power is n.
In Marvel comics, T'Challa (aka The Black Panther) as the king of Wakanda is estimated to be worth 90 trillion dollars.
Tony Stark (aka Iron Man) is only worth about 30 billion dollars.
If Tony Stark could somehow add a 10% increase in his wealth to his current worth each year.
Let t be a number of the years.
Then the equation is given as
[tex]\rm 9 \times 10^{13} = 3 \times 10^{10} \times (1.10)^t[/tex]
Then the value of t will be
[tex]\rm 3000= (1.10)^t\\[/tex]
Taking log both sides, we have
t (ln 1.1) = ln 3000
t = 84
