Answer:
The perimeter of the second square is 36 inches
Step-by-step explanation:
Given
Represent the sides of the squares with S1 and S2.
So:
--- Scale factor
--- perimeter of the first
Required
Calculate P2, the perimeter of the second
Represent the ratios of the perimeter:
Substitute 12 for P1
Equate both scale factors
Convert to fraction
Cross multiply
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Answer:
Holden's seed is 40 miles per hour
Step-by-step explanation:
The given parameters are;
The distance Holden drove = 110 miles
The time duration in which Holden drove = 2 and 3/4 hours = 11/4 hours = 2.75 hours
Therefore, Holden's speed, s, can be found from the relationship;
Speed, s = Distance/time = 110 miles/(11/4 hours) = 40 miles per hour
Holden's seed = 40 miles per hour.
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.
