Answer:
20
Step-by-step explanation:
16=1 2/10R + -8
16+8= 12/10R
24=12/10R
R=20
x = 3/2
Step-by-step explanation:
Given equation is:

As we have to solve for x, x will be isolated on one side of the equation
So,
<u>1. Addition property of equality </u>
4x will be added on both sides

<u>2. Division property of Equality</u>
Dividing both sides by 6

Hence,
x = 3/2

Volume of a cylinder= (height) x area of the base (circle)
We know the height = 160 cm (given), let's find the radius of the base.
The circumference of the base = 87.92 = 2πR==> R=87.92/(2π) =13.993 cm
Area of circle = πR²=π(13.993)² = 615.128 cm²
Hence the volume of the cylinder = 615.128 x 160 = 92,420.48 cm³
The value of h(8) in h(x)= 6x - 17 is 31

What are functions:
Functions relate input and output. Therefore, a function takes elements from a set (the domain) and relates them to elements in a set (range).
h(x)= 6x - 17
Let's find h(8)
h(8) = 6(8) - 17
h(8) = 48 - 17
h(8) = 31

Answer:
Total chairs = 18×22= 396
so no. of extra chairs need = 468-396 = 72
Now( 72/18) rows = 4 rows
Therefore 4 more rows are needed here
