6 groups of 3 6 times 3 which equals 18
and 18 divided by 4 is 4.5 so it takes 5 cars.
Step-by-step explanation:
A
160 >= 20 + 35x
x being the number of hours renting the canoe.
and we have to pay first $20 flat, no matter what. and then the hourly rate begins to "tick".
B
140 >= 35x
x <= 4
and actually, to make practical sense,
0 < x <= 4
as we want to apply this only, if we truly rent a canoe. 0 hours renting (or even negative numbers) does not make any sense.
C
with the given budget of $160 we can rent a canoe for maximum 4 hours.
1) Draw a right triangle with these measures:
angle with the horizontal: 6 degress
horizontal segment: 5
height: x
2) Definition of tangent : tan(6°) = opposite leg / adjacent leg = x / 5 =>
3) Solve for
x = 5tan(6°) = 0.53 miles
Answer: 0.53 miles
Answer:
Elena's move will lead to the solution of the problem
Step-by-step explanation:
To solve the equation 7.5d=2.5d, Lin divides each side by 2.5d, and Elena subtracts 2.5d from each side. Will both moves lead to the solution? Explain your reasoning
Given:
7.5d = 2.5d
Lin divides each side by 2.5d, Lin:
7.5d / 2.5d = 2.5d / 2.5d
3 = 1
This can not be the solution to the problem because 3 can not be Equal to 1
Elena subtracts 2.5d from each side
7.5d = 2.5d
7.5d - 2.5d = 2.5d - 2.5d
5d = 0
This can lead to the solution of the problem
Elena's move will lead to the solution of the problem
$1.29/(35 oz) = $0.043/oz
$1.20/(24 oz) = $0.05/oz
The 35-oz drink is a better buy.
