Answer:
21.71
Step-by-step explanation:
1) you need to order then by the size
3, 13, 14, 16, 27.42, 37.97 ,64, 95
2) if there is an odd amount of numbers then the median would be the center term. but if it an even number then you add the two middle terms together and divide them by 2.
16+27.42= 43.42
43.42 divided by 2=21.71
Hope this helped
Answer:
The correct answer is option A. Base = 11 cm and height = 13 cm
Step-by-step explanation:
It is given that, height of a triangle is 2 cm more than its base.Then height is increased by 2 cm.Then the area of triangle becomes 82.5 cm²
<u>To find the base an d height of original triangle</u>
Let x be the original base 'b' then the height h = x + 2
New height h = x + 2 + 2 = x + 4
Area = bh/2
82.5= (x(x + 4)/2
165 = x² + 4x
x + 4x - 165 = 0
Solving we get x = 11 and x = -15
Take positive value x = 11
Therefore base = 11 and height = x + 2 = 13 cm
The correct answer is option A. Base = 11 cm and height = 13 cm
Answer: 6 goes on 6/// 83 goes on 9///// 40goes on 6///// 64 goes on8///and the 7.5 will go between 7 and 8
Step-by-step explanation:
go onto a calculator and type in the number and decide it by the square root
Answer:
The height of the pyramid is 5m
Step-by-step explanation:
To calculate the heigth of a pyramid we have to use the following formula:
v = volume = 70 m³
w = width = 6 m
l = length = 7 m
h = height
v = (w * l * h) / 3
we replace the values that we know
70m³ = (6m * 7m * h) / 3
70m³ * 3 = 42m² * h
210m³ / 42m² = h
5m = h
The height of the pyramid is 5m
