A cylindrical coil of copper wire has 700 turns of diameter 4 cm
a. Use the value 22/7 for pi to find length of the wire
Answer:
8800 cm
Step-by-step explanation:
length of one turn = circumference of the circle = [tex]\pi [/tex] x diameter = 4[tex]\pi [/tex]
So 700 turns = 700 x 4[tex]\pi [/tex] = 2800[tex]\pi [/tex]
You are told to use 22/7 for [tex]\pi [/tex]
Therefore, length of the wire = 2800 x 22/7 = 8800 cm

Let a,b,c, be elements in group G. Show that ab and ba have the same order.
From the breakdown of the identity element in group G, we can say that;
It has been proved that ab and ba have the same order.
Let n and m be the order of ab and ba.
Thus;
(ab)ⁿ = e(ba)^(m) = eIn this case, e is the identity element of G.
Thus;
e = a(ba)ⁿ ¯ ¹b
Further simplification of this gives;
e = (ba)¯¹
Thus, we can say that;
(ba)ⁿ = e
Since the order m of ba divides n and we can also see that n divides m, it means that;
m = n.
In conclusion, we can say that the orders of ab and ba are the same.

Answer:
8/36, 9/36
Step-by-step explanation:
Denominators 9 and 4 have no common factors, so their least common multiple is their product: 36. Using a denominator of 36, the fractions can be written ...
[tex]\dfrac{2}{9}=\dfrac{2}{9}\cdot\dfrac{4}{4}=\boxed{\dfrac{8}{36}}\\\\\dfrac{1}{4}=\dfrac{1}{4}\cdot\dfrac{9}{9}=\boxed{\dfrac{9}{36}}[/tex]

There are 36 pencils in 6 packs. Igor wants to know how many pencils are in 1 pack. Elsa wants to know how many pencils are in 3 packs. Drag an expression to answer each question.
Answer:
Step-by-step explanation:
Hi! I dont know if i did this how your teacher wanted you to, but this is what i did:
36 divided by 6 is 6 - 36 ÷ 6
So, the answer for Igor is 6
So, because 6 is in one pack, 6 times 3 is 18 - 6 x 3
So, the answer for Elsa is 18.

Answer:
20x + 6.5Step-by-step explanation:
The perimeter of a triangle represents the sum of all sides.
=> Perimeter = (8x + 1.5) + (11x) + (x + 5)Removing the brackets:
=> (8x + 1.5) + (11x) + (x + 5)=> 8x + 1.5 + 11x + x + 5Addling like terms:
=> (8x + 11x + x) + (1.5 + 5)=> 20x + 6.5Hence, 20x + 6.5 is the perimeter of the triangle.
Angel earns $540 in 6 days. If he earns the same amount of money each day, how much does he
earn in 5 days?
Answer:
$450
Step-by-step explanation:
Because we are trying to figure out the amount five dasy and we know that 6-5=1 we are trying to figure out the unite rate. To find this out all we need to do is divide 540/6=90 because of this we know that the amount he earns per day is $90. If we subtract 540-90 we'll get $450 in five days
Paula drew a sketch of her office parking lot, as shown below. (Figure is not drawn to scale.) The scale Paula used for her drawing is 2 inches equals 5 yards. What is the actual length, in yards, of the parking lot? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:
16 1/4 or 16.25
Step-by-step explanation:
6 4/8 or 6 1/2 is the length of the drawing
Every 2 inches equal 5 yards.
Divide 6 1/2 / 2 = 3.25
There are 3.25 units of 2 inches in the drawing, so there are 3.25 units of 5 yards in the parking lot. 3.25 x 5 = 16 1/4

Given the speeds of each runner below, determine who runs the fastest.
Will runs 12 feet per second.
Zach runs 441 feet in 40 seconds.
Jake runs 1 mile in 533 seconds.
Ron runs 815 feet in 1 minute.
Answer:815 feet in 1 minute
Step-by-step explanation:
We know that 1 minute is 60 sec. So what you need to do is 815/60. You'd get 13.5833333333. When you divide every other number, it is lower than this one so the runner moving 815 per 60 sec is moving the fastest.

2(6x+7)+10x
4(3+3x)+2(1+3x)
Answer:
7(2+3x)-3x and 4(3+3x)+2(1+3x)
Step-by-step explanation:
7(2+3x)-3x
= 14 + 21x - 3x
= 18x + 14
2(6x+7)+10x
= 12x + 14 + 10x
= 22x + 14
4(3+3x)+2(1+3x)
= 12 + 12x + 2 + 6x
= 18x + 14
7(2+3x)-3x and 4(3+3x)+2(1+3x) are equal expressions.

Hector wants to tile his rectangle shed floor with rubber tiles. He found a company that will cut custom square tiles up to 60“ x 60“. The length of shed for is 240 inches and the width is 144 inches.
What is the side length of the largest square tile Hector can use to tile his shed floor so that they are no gaps or overlaps in the entire floor is covered
Answer:
48 inches
Step-by-step explanation:
The greatest common factor of 144 and 240 is 48. If Hector orders 48" square tiles, he can use 3 of them in the direction of the short dimension, and 5 of them in the direction of the long dimension.
The tiles can be 48 inches square.
__
Using Euclid's algorithm to find the GCF, we have ...
240/144 = 1 r 96
144/96 = 1 r 48
96/48 = 2 r 0 . . . . . 48 is the GCF
At each step, if the remainder from the division is not zero, we replace the larger number with the remainder and do the division again. The divisor that gives a zero remainder is the GCF.

20 as a product of primes:

Remember, primes have only two factors.
2 is only divisible by 1 and itself, and it's the only even prime number.
5 is also divisible by 1 and itself.
If we multiply 2 times 2 times 5, we will get 20.
