Answer:52
Step-by-step explanation:
Given
one-fifth of the plants in a garden are grape tomato plant
two-ninth of the plants in the garden are cherry tomato plants
Also there are 18 grape tomato and 20 cherry tomato plants.
Let Total plants be x
Then Grape tomato plants
x=90
thus there are total of 90 plants
also grape tomato+cherry tomato=18+20=38
Thus there are 90-38=52 remaining plants.
Answer:
Options (1), (3), (5) and (6)
Step-by-step explanation:
Option (1)
Both the circles M and H are same in shape. Therefore, both are similar.
True
Option (2)
MH = MS = [Radii of a circle]
MH = MO + OH
MH = ME + OH [Since, MO = ME]
MH = 10 + 25 = 35 cm
Area of circle M = πr²
= π(35)²
= 1225π
Area of circle H = π(25)²
= 625π
Area of M = 1.96(Area of H)
False
Option 3
OH + MS = 25 + 35
= 60 cm
True
Option 4
m∠HMS = 90°
Can't be figured out with the given informations
False
Option 5
Diameter of circle H = 2(radius)
= 2(25)
= 50 cm
True
Option 6
Circumference of circle S = 2πr
= 2π(ES)
Circumference of circle M = 2π(MS)
Ratio of the circumference of circle S and M =
=
True.
Options (1), (3), (5) and (6) are correct.
