5 years because when you divide 90 by 18 to get how many years it takes the tree to grow to 90 inches tall, you get 5.
32 students choose a favorite topping for their slices.
Let x be the total number of students.
1/2 of the total students, or 1/2x, choose pepperoni.
1/4 of the total students, or 1/4x, choose extra cheese.
1/8 of the total students, or 1/8x, choose sausage.
4 students choose mushrooms.
We know that together, these equal the total number of students, x:
1/2x+1/4x+1/8x+4=x
We will use 8 as the common denominator:
4/8x+2/8x+1/8x+4=x
Combining like terms:
7/8x+4=x
Subtract 7/8x from both sides:
7/8x+4-7/8x=x-7/8x
4=1x-7/8x
4=1/8x
Divide both sides by 1/8:
4÷(1/8) = 1/8x÷(1/8)
4/1÷(1/8) = x
4/1×8/1 = x
32/1 = x
32 = x
Answer:
A
Step-by-step explanation:
An octagon has 8 sides. Each side is given as 2a + 1
Perimeter = 8(2a + 1)
= 16a + 8
Answer: 16a + 8
Answer:


Step-by-step explanation:
Consider the provided number.
We need to find the approximate value of
to the nearest hundredth.
First find two perfect squares that the irrational number falls between.

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.


118 is closer to 121 as compare to 100.
Therefore, 
Consider the number 
First find two perfect squares that the irrational number falls between.

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.


319 is closer to 324 as compare to 289.
Therefore,
