The diameter of the circle is 361 units
Answer: point C and D
Step-by-step explanation:
i am in College so this is the right answer
hope this help
Both problems can be solved similarly since both shapes are Quadrilateral hence the sum of thier interior angels is 360
5.)
(x)+(x)+(4x-26)+(2x+18)=360
8x-8=360
x-1=45
x=46
6.)
(2x)+(x)+(x+10)+(2x-16)=360
6x-6=360
x-1=60
x=61
Andre walks more steps than Priya.
To find out who many steps each one of them walks in a week, we have to carry out different calculations starting with Andre.
Calculation for number of steps taken by Andre
Andre takes 6000 steps in 50 minutes. We can use this information to scale up his number of steps over a period of 5 hours(300 minutes.). The quickest way to do this calculation, is to notice that there are 6 different 50 minute segments in 300 minutes. This means that the number of steps taken in 5 hours is 
steps.
Another way to do this calculations is to use proportions
.
Andre takes 36000 steps that week.
Calculation for number of steps taken by Priya
The number of steps taken by Priya is given by the is given by the function 
where 
is the time in minutes. Priya walks for a total of 5 hours or 300 minutes. We calculate the number of steps she takes as shown below,
Priya takes a total of 35400 steps.
Since 36000 steps is greater than 35400 steps, we conclude that Andre walks more steps than Priya.
Answer: they need to cover 0.25 miles.
Step-by-step explanation:
Let x represent the total distance that they have to cover to get to Bernie's house.
Beth and Billy are biking to their friend Bernie's house and after 1 mile, Beth and Billy have traveled 4/5 of the total distance to Bernie's house. This would be expressed as
4.5 × x = 1
4x/5 = 1
Multiplying the left hand side and the right hand side of the equation by 5, it becomes
4x/5 × 5 = 1 × 5
4x = 5
Dividing the left hand side and the right hand side of the equation by 4, it becomes
4x/4 = 5/4
x = 1.25
Therefore, the remaining distance that they need to cover to arrive at Bernie's is
1.25 - 1 = 0.25 miles
