Answer:
The scale Henry used was 0.0002
Step-by-step explanation:
100m + 400m : 10 cm
500m : 0.1m
0.1/500 = 0.0002
In some instances of bivariate data, it is determined that one variable influences or determines the second variable, and the terms dependent and independent variables are used to distinguish between the two types of variables. In the above example, the length of a person's legs is the independent variable.
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
Answer:
80 Passengers
Step-by-step explanation:
A kilo gram is equal to 1,000 grams.
So 90 times 1000 is how much one passenger weighs in grams.
90,000 is one passenger.
Divide
7,200,000/90,000=80
Your answer is 80 passengers
