Answer:
The variable is t
t represent the cost of movie tickets
Step-by-step explanation:
Given:
Total cost = 7t + 4.50
The variable is t
Michael + 6 friends = 7 people
4.50 represent the cost of popcorn
t represent the cost of movie tickets
For instance,
If the cost of a movie tickets is $2
Then,
t = 2
Total cost = 7t + 4.50
= 7(2) + 4.50
= 14 + 4.50
= 18.50
Total cost = $18.50
Total no. of births = 2000
Births of girls = 64
Birth% of girls




Hence, the number of girls are significantly low.
Building and solving an equation to model the situation, it is found that it takes 4 min for the prairie dog to reach 13 feet underground.
- Initially, the dog is 5 feet underground.
- Each minute, the dog goes 2 more feet underground.
Hence, the underground height of the dog after t seconds is given by:

The time it takes for the dog to reach 13 feet underground is <u>t for which h(t) = 13</u>, hence:





It takes 4 min for the prairie dog to reach 13 feet underground.

Given that
The length of the rectangle 4cm and the breadth is 3cm
Area of rectangle= length * breadth
Area= 4*3
= 12cm^2
