Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5
Answer:12
Step-by-step explanation:
Answer:Then 16x = 240, and x = 240/16 = 15. It will take 15 minutes to travel 12 miles.
Step-by-step explanation:
16 miles = 12 miles
20 mins. how many mins?
16 = 12 cross multiply 16? = 240 divide by 16 240 divided by 16 = 15 miles
20 ? because 15 x 16 = 240
The linear relationship which exists between the change in weight and number of days of hibernation in a hedgedog can be modeled using the equation y = - 0.03 + 0
- Change in weight per day of hibernation = - 0.03
- Change in weight for 115 days = - 3.45 ounces
A linear model can be created using the data in the table given using a regression calculator or excel ;
The linear model obtained in the form y = m + bx is :
- y = - 0.03x + 0
- y = change in weight
- x = number of days of hibernation
- Intercept = 0
- Slope = -0.03
- The slope value of the function gives the change in weight value per number of days of hibernation ; which is -0.03.
- Using the regression equation, substitute, the vlaue of x = 115
- -0.03(115) + 0 = - 3.45
Therefore, the change in weight after 115 days of hibernation is - 3.45 ounces.
