In the diagram Shown a 2-foot wide flower border surrounds the heart-shaped pond. What is the area of the border?
!!PLEASE HELP!!
Answer:
Step-by-step explanation:
Area of square = 144 sq ft
Area of circle = πr² = 36π sq ft
Total area = (144+36π) sq ft
Square section of pond is 10 ft by 10 ft, area = 100 sq ft
Circular area of pond has diameter of 8 ft.
Area = πr² = 16π sq ft
Area of pond = (100+16π) sq ft
Area of border = (144+36π)-(100+16π) = (44+20π) sq ft
True or False?
k = 2 is a solution to the inequality 8k+ 4 > 18.
Answer:
True
Step-by-step explanation:
If k = 2, then we plug in 2 for every instance there is a k. So...
8k + 4 > 18
Will turn into...
8(2) + 4 > 18
Then solve using PEMDAS (or whatever you were taught. Parenthesis, Exponent, Multiplication/Division, Addition/Subtraction.)
16 + 4 > 18
20 > 18
Since 20 is greater than 18, 2 can be a solution for this inequality.

The Harvey family stayed at a hotel for n nights. The cost was $80 per night plus a one-time fee of $20 because they brought their dog. Which expression represent the total cost of their hotel stay.
80n + 20n
80n + 20
80 + 20n
80 + 20 + n
Answer:
80n + 20
Step-by-step explanation:
20 stays the same because it's a one time fee. Then, for every night the Harvey family stays, it costs them eighty dollars. So, it's 80n + 20
Answer: 80n+20
Step-by-step explanation:
80 is the cost of nights you stayed but you don’t know the number of nights they dated so you place n next to 80 and they payed an additional 20 fee so you add that to 80n

Pleas help me and can you explain how you got it.
Answer:
21
Step-by-step explanation:
straight line = 180 degrees ( H,D,R)
180 = 7x - 3 + 2x - 6
180 = 7x + 2x - 3 - 6 (group the same type number together)
180 = 9x -9 (simplify the numbers)
189 = 9x (+9)
21 = x (divide by 9)

A Mars rover descended from the rim of a crater at a constant rate. After 2 days, the rover's elevation was 106 meters. After 6 days, its elevation was 48 meters. What elevation did the rover start at? ____meters Complete the equation that describes the relationship between the rover's elevation in meters, E, and the elapsed time in days, t. Write your answer using whole numbers or decimals rounded to the nearest tenth. E= ___ t+____
Answer:
135
E = - 14.5t + 135
Step-by-step explanation:
Given that, descent rate is constant ;
Elevation after 2 days = 106 m
Elevation after 6 days = 48 m
Let
Rate of elevation per day= x
Initial elevation = a
Hence,
a - 2x = 106 - - - (1)
a - 6x = 48 ___(2)
-2x + 6x = 106 - 48
4x = 58
x = 58/4
x = 14.5 meters per day
Hence, initial elevation :
a - 2(14.5) = 106
a - 29 = 106
a = 106 + 29
a = 135
Relationship between Rover's elevation, E and elapsed time, t
E = - 14.5t + 135
-14.5 = rate per day

Find the mean and median travel times for these students.
If necessary, round your answers to the nearest tenth
Mean: _ minutes
Median: __ minutes
Answer:
mean: 65
median: 9
Step-by-step explanation:
You take all the numbers you have and add them up. Make it simple by adding smaller numbers together. Then once you have the total which is 65 you divide it by the total of numbers you have and then round because after dividing you get 8.125 and the safest way to round is to 9.
