Answer:
t=v/d
Step-by-step explanation:
id think that there are two steps
v=d/t
divide D on both sides
v/d=d/t/d
v/d=t
Answer:
90
Step-by-step explanation:
Answer:
Easy
Step-by-step explanation:
To find the perimeter, add all the sides together.
12+16+20=48
To find the area, you multiply the sides that make the right angle of the triangle,
12×16=192
And divide it by two. This step is important as if you don't divide it by two, you will end up with the area of a square.
192÷2=96
Finito. Oh and don't forget to add units.
Cm for perimeter and Cm(squared) for area. :)
Answer:
6.25 % of area of Large triangle = area of smallest triangle
Step-by-step explanation:
Area of large triangle L = (1/2)*base*height
L = (1/2)*(44 m)* h
L = 22*h square m.
2nd equilateral triangle area: S =(1/2)*(22 m)*(0.5h)
S = 5.5*h sq. m.
3rd smallest equilateral triangle area : T = (1/2)*(11 m)*(0.25h)
T = 1.375*h sq. m
-----
Find percent P where T = P* L, 1.375*h = P * 22*h
P = 6.25% = 0.0625
Let number be x
2x - 5 = 3
2x = 3 + 5
x = 8 / 2
= 4
The number is 4
