Triangle A is a scaled version of triangle B. The dimensions of triangle A are twice the dimensions of triangle B. The area of triangle B is 40.5 sq cm. What is the area of triangle A?
Answers
Step-by-step explanation:
the lengths of any line (side, height,...) in A is twice as long as in B.
now, the area of a triangle is
baseline × height / 2
so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4
therefore, the area of A is
40.5 × 4 = 162 cm²

Starting position of mine shaft is = 10m above ground
but,
it moves in opposite direction so it travels the distance (-350 m ) below the ground.
Total distance covered by mine shaft = 10m - (-350m)
= 10 + 350
= 360m
Now, taken to cover a distance of 6m by it = 1 minute
Time taken to cover a distance of 1m by it = \frac{1}{6\ }\min
Therefore, tie taken to a cover a distance of 360m = \frac{1}{6}\times\ 360\ =\ 60\ \min\ \
60 minutes = 1 hour
thus, in one hour the mine shraft reaches = 350 below the ground

The following dataset represents the number of minutes a student listens to music in a week for 50 students, sorted and
arranged in rows of 5. What is the 80th percentile of the data?
Answers
Using the percentile relation, the 80th percentile of the data is 77.
The 80th percentile of a data can be defined as :
80th percentile = 80% × (n+1)th term n = sample size = 50Hence, we have ;
80th percentile = 0.8 × (50 + 1)th term
80th percentile = 40.8 term = 41th term
Since, the days is sorted, the 80th percentile is the value at index 41.
Hence, the 80th percentile of the data is 77.

a^2+b^2= c^2
In this scenario,

The missing side length of the right angle triangle is 20
How to solve missing sides using Pythagoras theoremPythagoras theorem States that the square of the longest side of a triangle is equal to the sum of the square of the opposite side and no square of the adjacent side.
The diagram is a right angle triangle with sides AB, BC and CA.The longest side is BCBC² = AB² + CA²
(15 + 6)² = x² + 8²
21² = x² + 8²
21² - 8² = x²
441 - 64 = x²
377 = x²
find the square root of both sidesx = √377

Find perimeter of the house
Answers
Answer:
50x +11
Step-by-step explanation:
The perimeter is the sum of the lengths of the 5 sides. Sides marked with the same symbol have the same length. We can use multiplication to simplify the repeated addition.
P= (14x +13) +2(12x +3) +2(6x -4)
P = (14 +2·12 +2·6)x +(13 +2·3 +2(-4))
P = 50x +11
The perimeter of the house is 50x +11.
