Answer: The car travels 97.5 miles in 1.5 hour.
Step-by-step explanation:
Given: A car is traveling down a highway at a constant speed, described by the equation , described by the equation [tex]d=65t[/tex], where represents the distance, in miles, that the car travels at this speed in t hours.
To find : Number of miles car travel in 1.5 hour.
Simply put t= 1.5 in the given expression , we get
65(1.5)= 97.5

Answer:
strong positive maybe
The direction and strength of the association between the variables is weak negative correlation. Therefore, option A is the correct answer.
The given coordinates are (0, 8), (12, 0), (2, 5), (10, 1), (9, 3), (5, 2), (6, 2) and (4, 0).
What is correlation and types?Correlation is a key statistical measure that describes the degree of association between two variables. There are three basic types of correlation: positive correlation: the two variables change in the same direction. negative correlation: the two variables change in opposite directions.
The coordinate points (0, 8), (12, 0), (2, 5), (10, 1), (9, 3), (5, 2), (6, 2) and (4, 0) are plotted in the graph below and it shows weak negative correlation.
The direction and strength of the association between the variables is weak negative correlation. Therefore, option A is the correct answer.

Taino went to a professional basketball game. He spent $54.85 for a ticket, $4.99 for a hot dog, and $2.15 for a soda. What is the total amount that he spent? Use mental math to find the sum.
Answer:
$61.99
Step-by-step explanation:
To find the total, we need to add.
Let's start with the ticket and the soda.
54+2=56
0.85+0.15=1
56+1=57
Next, add the price of the hot dog.
4.99 rounds to 5, so 57+5=62
62-0.01=61.99 (here we subtracted the one cent we originally rounded up)
$61.99

Write the final algebraic equation with variables on both sides. Include what the variable represents in the problem. Include appropriate units. ____________________________________________________________
Answer:
see below
Step-by-step explanation:
a. We want to see when the two snakes will be the same length.
b. b1 + r1m= b2 + r2m where b is the initial length and m is the number of months and r is the growth rate
c. for the anaconda 5.23 + 1.27 m where m is the number of months, and the total length is in meters
The anaconda starts at 5.23 meters and grows 1.27 meters each month for m months
d. for the python 4.76 + 2.04m where m is the number of months, l is the length of the python in meters
The python starts at 4.76 meters and grows 2.04 meters each month for m months
e. 5.23 + 1.27 m = 4.76 + 2.04m m is the number of months Each side is the number of meters
Chloe wants to divide 600 jellybeans into equal groups. She wants each group to have more than 10 jellybeans, but less than 100. What are three possible groupings Chloe can make?
Answer:
8 groups of 75, 10 groups of 60, 12 groups of 50.
Step-by-step explanation:
600/12=50
600/10=60
600/8=75
The possible groupings are:
50 groups with 12 jellybeans each.
40 groups with 15 jellybeans each.
30 groups with 20 jellybeans each.
24 groups with 25 jellybeans each.
12 groups with 50 jellybeans each.
10 groups with 60 jellybeans each.
8 groups with 75 jellybeans each.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
Chloe wants to divide 600 jellybeans into equal groups. She wants each group to have more than 10 jellybeans, but less than 100.
This means,
we need to find three numbers between 10 and 100 that are a factor of 600.
We can have,
12, 15, 20, 25, 50, 60, 75
We can have,
50 groups with 12 jellybeans each.
40 groups with 15 jellybeans each.
30 groups with 20 jellybeans each.
24 groups with 25 jellybeans each.
12 groups with 50 jellybeans each.
10 groups with 60 jellybeans each.
8 groups with 75 jellybeans each.
These are the possible grouping we can have,
We can choose any three groupings.
Thus,
The possible groupings are:
50 groups with 12 jellybeans each.
40 groups with 15 jellybeans each.
30 groups with 20 jellybeans each.
24 groups with 25 jellybeans each.
12 groups with 50 jellybeans each.
10 groups with 60 jellybeans each.
8 groups with 75 jellybeans each.
