Answer: 17.14 ft
<u>Step-by-step explanation:</u>
The area of the flower bed is 60 ft x 80 ft = 4800 ft²
The perimeter of the sidewalk that surrounds the flower bed is:
- 2(60 ft) + 2(80 ft)
- = 120 ft + 160 ft
- = 280 ft
The area of the sidewalk is:
area of sidewalk = area of flower bed
280w = 4800


≈ 17.14
Answer:
52
Step-by-step explanation:
Let x represent the smallest of the three numbers. Then the other two are (x+2) and (x+4). Their sum is ...
x + (x+2) +(x+4) = 162
3x = 156 . . . . . . . . . . . .subtract 6
x = 156/3 = 52
The smallest of the three numbers is 52.
___
I like to work problems like this by considering the average number. Here, the average of the three numbers is 162/3 = 54, the middle number of the three. Then the smallest of the three consecutive even numbers is 2 less, or 52.
Answer:
3. 10 - 5 is 5. so that is the difference. difference means subtraction.
4. 108 - 30 = 78. so she can move 78 degrees miore after therapy because 108 minues 30 is 78
5. 99 because 180 - 81 = 99. there is always 180 degrees in a line angle.
6. 130 degrees. 25 + 25 = 50 so 180 minus 50 equals 130

Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m =
= 
note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2
y =
x - 2 ← equation of line
The common ratio is 24 x 2 = 88 x 2 = 1616 x 2 =32
