Answer:
The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board
step 1:
Find the area of the square game board
"A=b^{2}"
we have
b=20cm
"substitute"
A=20^{2}
=400cm²
step 2:
Find the probability
P=314/400
=0.785
=0.785 x 100
=78.5%
3-3 0

The edge lengths of a triangle are inversely proportional to 2,3 and 4.
The actual proportions of the lengths are then
12(1/2:1/3:1/4)=6:4:3
The longest side
= 39* (6/(6+4+3)
= 39*6/13
=18
2. 63 breads : 35 kg flour
is the same as
54 breads : x kg flour
Cross multiply and get
x=54*35/63=30
30 kg of flour are needed to make 54 breads.
Hey! you would first for 9 its a one step equation so you would divide the number without the variable(constant) by both sides you would get and answer by having the variable on one side of the equation sign and you have your answer. since it was multiplying you had to divide to cancel out the number next to the variable . If you need more help i recommend PhotoMath because it shows you how to do the problems step by step and shows you the answer! Thanks for asking for help
