Answer:
Step-by-step explanation:
What is the average speed of a biker if she biked 4 1/4 of a mile in 25 minutes?
-----------------
rate = distance/time
-----
rate = (17/4)/(25/60) = (17/4)(60/25) = (17*3/5) = 51/5 = 10.2 mph
----------------
The inequality shown on the number line is -3 < x ≤ 2
Inequality means when the two values that are not equal is defined by inequalities. Inequality means unequal.
When two values are not equal we will greater than or less than sign .
" < " means less than
" >" means greater than
"≤ " means less than and equal to
"≥ " means greater than and equal to
(a) Inequality -4 < n ≤ 5
here , -4 is not included so, the Number line starts from -3
5 is included so, number line will end on 5
(b) The number line shows ,
line is starting from -3 but the dot is not filled means it is not included
The line ends at 2 so,
Inequality is -3 < n ≤ 2

Answer:
20 ft
Step-by-step explanation:
Given;
Length of flagpole shadow = 30 ft
Sign post height = 4 ft
Length of sign post shadow = 6 ft
Since the two objects are close to each other (the same location)
The height and shadow length of the two objects follows the same ratio, just like similar triangles;
Using the Ratio or similar triangles Formula;
height of flagpole/flagpole shadow length = height of sign post/ sign post shadow length
Substituting the values;
h/30 = 4/6
h = 4/6 × 30 = 20 ft
Flagpole height = 20 ft
