Arithmetic sqaure: a + (n-1) * d
<em> </em><u><em>where "a" is the first term, "d" is the common difference</em></u>
Here given:
a = 10 gallons
d = 5.5 gallons
- nth term: 10 + (n-1) * 5.5
<u>Solve for first 5 terms</u>:
10 + (1-1) * 5.5 = 10
10 + (2-1) * 5.5 = 15.5
10 + (3-1) * 5.5 = 21
10 + (4-1) * 5.5 = 26.5
10 + (5-1) * 5.5 = 32
first five terms: 10, 15.5, 21, 26.5, 32

that is the procedure above
Answer:
Area: 3.7 ft²
Ratio: 73.14 : 1
Step-by-step explanation:
Perimeter of an octagon = 8*side
Replacing with perimeter = 7 ft:
7 = 8*side
side = 7/8 ft = 0.875 ft
that is, each side of the model is 7/8 ft length.
Area of an octagon = 2*(1 + √2)*side²
Area of an octagon = 2*(1 + √2)*(7/8)²
Area of an octagon = 3.7 ft²
Perimeter of real gazebo = 8*8 = 64 ft
Then, the ratio of the perimeters (in feet) of the real gazebo floor to the model gazebo floor is 64:0.875. Multiplying each term by 8/7, we get 73.14:1
The -9 because absolute value is the number itself without positive or negative. So it’s the 9. Hope this helps!
Answer:
, so using order of applications, it simplifies to 27+1.5+9 after multiplying and dividing, and the final answer is 37.5
