Answer:
Average mature trees are from 200 to 240 feet high with diameters of 10 to 15 feet at 4 feet 8 inches above the ground. Exceptional individuals sometimes reach a height of 350 feet, a diameter of over 20 feet, and an age of approximately 2000 years. Redwood leaves are green, flat, and sharp-pointed.
question 1=30
question 3 =1/20
Step-by-step explanation:
question 1
- 300/2×5
- 300/10
- 300\10 you will take by 0 0
- so the ans is 30/1
- answer is 30
question 2 am not sure
question 3
- it is 20/1
- so the reciprovol of 20/1 is 1/20
- that's all I know for no 2 I will some one. thanks
Answer:
9
Step-by-step explanation:
the answer is 9 because 7=y so , 7+2=9
Given that the perimeter of rhombus ABCD is 20 cm, the length of the sides will be:
length=20/4=5 cm
the ratio of the diagonals is 4:3, hence suppose the common factor on the diagonals is x such that:
AC=4x and BD=3x
using Pythagorean theorem, the length of one side of the rhombus will be:
c^2=a^2+b^2
substituting our values we get:
5²=(2x)²+(1.5x)²
25=4x²+2.25x²
25=6.25x²
x²=4
x=2
hence the length of the diagonals will be:
AC=4x=4×2=8 cm
BD=3x=3×2=6 cm
Hence the area of the rhombus wll be:
Area=1/2(AC×BD)
=1/2×8×6
=24 cm²
