Similar figures are two different figures of different sizes, but have the same shape
Answer:
<h2>
9/35, 0.257 or 25.7%</h2>
Step-by-step explanation:
The basic and simple way to calculate the probability of an event happening is by using this equation:
<h2>Number of desired outcomes</h2><h2>------------------------------------------------- = Probability </h2><h2>Number of all possible outcomes</h2><h2 />
Our desired outcomes are picking either red or yellow candies. The number of desired outcomes in this case is the total number of red and yellow candies. 6 red + 3 yellow = 9
Number of desired outcomes = 9
Number of all possible outcomes in this case is the total number of candies in the bag. 10 green + 8 brown + 3 yellow + 8 blue + 6 red = 35
Number of all possible outcomes = 35
Use the formula and we get that the probabbility of drawing out a yellow or red candy is: 9/35, 0.257 or 25.7% (those are 3 different ways to write the probability)
Answer:
Part a) System of equations:
g = 5 b
b + g = 120
Part b) There were 20 boys, and 100 girls at the dance.
Step-by-step explanation:
Part a)
We start by writing a mathematical expression associated with he two given statements:
1) "Five times as many girls as boys" using "g" to represent the number of girls, and "b" for the number of boys:
g = 5 b
2) a "Total of 120 students" ...
This means that the addition of boys "b" and girls "g" should render 12:
b + g = 120
Part b)
Solve for the number of boys and girls by first replacing (substituting) "g" with "5 b" in the second equation, solving for "b":
b + 5 b = 120
6 b = 120
b = 120/6
b = 20
and now that we know the number of boys, finding the number of girls "g" using the first equation:
g = 5 (20)
g = 100
Answer:
40,608,000 km or 4.0608× km
Step-by-step explanation:
Speed(km/h) = Distance(km)/Time(Hours)
Distance = Speed × Time
6 days = 24 × 6 = 144 hours
282,000 km/h × 144 hours = 40,608,000 km
