Answer:
A= 27500 seats, B= 14200 seats, C= 13300 seats
Step-by-step explanation:
a=b+c
a+b+c=55000 seats
30a+24b+18c=1405200 dollars
substitue a for b+c
b+c+b+c=55000
30(b+c)+24b+18c=1405200
seats 2b+2c=55000 --> divide by 2 on both sides b+c=27500 --> c=27500-b
dollars 30b+30c+24b+18c=1405200 --> 54b+48c=1405200 divide by 6 --> 9b+8c=234200
substitute c for 13750-b
9b+8(27500-b)=234200
9b+220000-8b=234,200
b=14,200 seats
c=27500-b=27500-14200=13300 seats
a=55000-b-c=55000-27500=27500 seats
you do 15.0 x 4.0 and that would give you the answer of 60.
the bridge is 60m above the water.
Answer: 1,045 passengers
Step-by-step explanation:
This question involves multiple steps. Let's first try to figure the number of children on the cruise.
The ratio of girls to the total number of children was 2:5. There are 198 boys.
This information tells me that for every 5 children, there's 2 girls and 3 boys.
Based off of this information, we can divide the total number of boys by 3 in order to find the number of children.
198÷3=66
Let's multiply 66 by 5 since that's the number of groupings based off the ratio.
66×5=330
Let's check the number of children. Since the ratio of girls to total children is 2:5 and we already confirmed there's 198 boys, there should be 132 girls. We can turn this ratio into a fraction where 2/5 of the children are girls. we can confirm this by multiply 330 by 2/5 (0.4) and getting 132.
There are 330 children on the cruise.
The ratio of the number of adults to the number of children was 13:6.
For every 6 children, there were 13 adults. Let's divide the number of children by 6 in order to find the number of groupings.
330÷6=55
Let's now multiply the groupings by 13 to find the number of adults.
55×13=715
So there should be 715 adults and 330 children on the cruise.
715+330=1,045
A set of ordered pairs is called a relation. The set of all first components of the ordered pairs of a relation is the domain of the relation, and the set of all second components of the ordered pairs is the range of the relation. :)
Answer:
3/4
Step-by-step explanation:
We need two points to find the slope
( 20,20) and (60,50)
m = (y2-y1)/(x2-x1)
= (50-20)/(60-20)
= 30/40
= 3/4
