Multiple the all fraction and the x marks relating to how many there are.
Then Add then all up. Finally, divide by how many x marks there is.
2(1/8)+4(1/4)+2(3/8)+2(1/2) = 3
------> 3 / number of x, 3 / 10 or.3
There are 10 possible results _:- 1 through 10
possible choices for odd or multiple of 5 are 1,3,5,7,9,10 - 6 numbers
so required probability = 6/10 = 3/5
Answer:
34. a) 10 students
35. b) Together green and red make up the half of the students
Step-by-step explanation:
For number 34, the answer is 10 because it is one-fourth of 40 which is same as 40 divided by 4 which is 10.
For 35, green and red do not add up to one half
Hope it helped you!
Answer:
226.9 in²
Step-by-step explanation:
The formula for circumference of a circle is:
C = 2πr, where π = 3.14 and r = the radius
The formula for area of a circle is
A = πr²
First, using the formula for circumference, you can solve for 'r':
53.42 = 2πr or 53.42 = 6.28r (divide) r = 8.5
Now, use the value of 'r' to solve for area:
A = π8.5² or 3.14(8.5)² = 226.9 in²
Answer:
a) 15.625 cm²
b) 8 cm²
c) 50 cm²
d) 12 cm²
Step-by-step explanation:
a) area of a parallelogram = base x height
⇒ area of yellow shape = 1/2 x base x height
= 1/2 x 12.5 x 2.5
= 15.625 cm²
b) area of triangle = 1/2 x base x height
= 1/2 x 2 x 8
= 8 cm²
c) area of a parallelogram = base x height
area yellow parallelogram = (10 x 6) - (5 x 2) = 50 cm²
d) area of a parallelogram = base x height
⇒ area of a 1/2 parallelogram = 1/2 x base x height
⇒ area yellow shape = 1/2 x 12 x 2 = 12 cm²
