Koda needs 84 inches of ribbon to put it around the edge of the board.
A classroom board is 24 inches wide and 18 inches tall, Koda s putting ribbon along the outside edge of the board.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
Here,
length = 24 inch
width = 18 inch
The perimeter of the board, = 2 {length + width]
= 2 [24 + 18]
= 84
Thus, Koda needs 84 inches of ribbon to put it around the edge of the board.

What are the values of a1 and r of the geometric series?
2 – 2 + 2 – 2 + 2
a1 = 2 and r = –2
a1 = –2 and r = 2
a1 = –1 and r = 2
a1 = 2 and r = –1
Answer:
a1=2 and r=-1
Step-by-step explanation:
"A geometric series is a series with a constant ratio between successive terms".
Here, we can observe that the first term 'a' is '2'.
And the common ratio 'r' =
Therefore, the first term 'a' is 2 and common ratio 'r' is '-1'.
First term, a, is 2. Next term, -2, is the product of 2 and -1 and is -2. Next term, 2, is the product of -2 and -1. Thus, the first term, a, is 2 and the common ratio, r, is -1
Answer:
a1 = 2 and r = –1

Solve for x
4x-16 2x+16
Answer:
The value of x is equal to 30.
Step-by-step explanation:
Let's define what are 2 equations are:
Since we are dealing with a straight line, the line's angle will always equal 180°.
Since the 2 angles must add up to 180°, then they must be supplementary angles.
We can set up our equation to solve for x:
4x - 16 + 2x + 16 = 180This equation states that the 2 angles, given in formulas, must be equal to the angle of the line.
We can now solve this equation and get a value of x:
Define:∴ we have found the value of x to be equal to 30.

what number should be added to both sides in order to solve x^2 -8x=0
Answer:
16
Step-by-step explanation:
x^2 -8x=0
rewrite in this form and add 16 to both sides:
x² + 2(- 4)x + 16 = 0 + 16
(x - 4)² = 16 ( take square root of both sides )
x - 4 = ± 4
x = 4 ± 4

What is the total number of unique triangles that can be formed with side lengths of 6.5 centimeters, 6 centimeters, and 2.5 centimeters?
Enter your answer in the answer box below.
Answer:
One
Step-by-step explanation:
For unique triangles with 3 sides, the sum of the two shorter sides must be greater than the third side.
Shorter sides: 6 cm and 2.5 cm
Longer side: 6.5 cm
6 + 2.5 = 8.5
As 8.5 > 6.5 this is a unique triangle
As the side lengths are fixed, only one unique triangle can be formed.

In rectangle EFGH, the length of EF is 12 units and the length of FG is 5 units. The rectangle is translated 6 units to the right and 4 units down to produce rectangle WXYZ. What is the length of YZ ?
Answer: 12
Step-by-step explanation:
Because a translation is a rigid motion, we know that YZ corresponds to GH (and they will have the same length).
Now, we can the fact that EFGH is a rectangle to obtain that EF=GH=12 (since opposite sides of a rectangle are congruent)
Hence, YZ=12.

If instead of randomly selecting two people there were five, what is the probability that all five are right-handed
Answer:
1/32
Step-by-step explanation:
We can break this question down. If we had 1 person and they are right-handed, the probability is 1/2 because they are either left-handed or right-handed. Knowing that, we can multiply the probability of having 1 person being right-handed 5 times because there are 5 people in the question.
1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 1/(2⁵) = 1/32
Therefore, the probability of randomly selecting 5 people who are right-handed is 1/32.

A geometric sequence can be used to describe the population of rabbits on a
farm. The first spring, the farmer purchased 8 rabbits. Five years later, there are
648 rabbits at the farm. Assuming that none of the rabbits leave the farm, how
many rabbits were on the farm in year 3?
Answer:
step 1
Find the average growth per year of the populations of rabbits farm A
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=40
average=[40-5]/2---------> 17.5
step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=30
average=[30-5]/2---------> 12.5
step 3
Compare the average growth per year of the populations of rabbits on both farms
farm A=17.5
farm B=12.5
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.
therefore
the answer is the option C)
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.

A factory inspector found flaws in 4 out of 22 wooden boxes. Considering this data, how many flawed boxes would you expect the inspector to find in a batch of 44 boxes
Answer:
8
Step-by-step explanation:
We can form a simple ratio to solve this problem.
Flaws:Total Box
Plug in current values
4:22
44/22 = 2
Multiply the ratio by 2
8:44
8 boxes would be flawed.
Answer:
8
Step-by-step explanation:
There are 2 ways to do this I have seen.
1. 4/22 will get you .18, you can then multiply that by 44 and get 8
2. 22*2 is 44 so you can assume the number of flaws will also be the same amount multiplied (a multiple of 2) and you will get 8
