Important information:
The string is 8.5 inches long.
1 inch = 2.54 centimeters
How to solve:
Multiply both sides by 8.5 to get 8.5 inches = x centimeters.
2.54 • 8.5 = 21.59
Answer:
8.5 inches equals 21.59 centimeters.
Hope this helps! :)
Answer:
the actual distance is 1800 ft.
Step-by-step explanation:
Proportion states that the two fractions or ratios are equal.
Let x be the actual distance.
As per the statement:
Reggie was looking at a map of the school the scale shows that 1 inch equals 150 ft.
⇒1 inch = 150 ft.
if the distance between his classroom in the cafeteria measures 12 in on the map.
by definition of proportions we have;
By cross multiply we have;
ft
Therefore, the actual distance is 1800 ft.
The length of BC would be 6ft
ANSWER
All real numbers greater or equal to -3.
EXPLANATION
The domain of the given function are values of x that make the function defined.
We can see from the graph that, the domain are x-values greater than or equal to -3.
In other words, we can find a corresponding y-value for all x-values greater than or equal to -3.
The correct answer is option D.
Answer:
f(x) = 30 • 0.989x
Step-by-step explanation:
Given the data :
10 26.8
20 23.9
30 21.3
40 19
50 16.9
60 15.1
Using technology, the exponential model equation obtained by plotting the data is :
y = 30.068(0.989)^x
Based on the general exponential formula :
y = ab^x
y = predicted value
Initial value, a = 30.068
Rate = b = 0.989
The most appropriate model equation from the options given is :
f(x) = 30 • 0.989^x
