A thread is wound 200 times round a reel of diameter 5 cm. Use the value 3 for it to find the approximate length of the thread in metres.
Answer:
Length of the thread = 30 metres
Step-by-step explanation:
Length of the thread in one round of a reel = Circumference of the reel
C = [tex]2\pi r[/tex]
Since radius of the reel = [tex]\frac{\text{Diameter}}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 2.5 cm
Circumference of the reel = 2(π)(2.5)
= 5π
= 5×3
= 15 cm
Length of the thread wound in one round around the reel = 15 cm
Since, thread is wound 200 times round a reel, length of the thread
= 200 × 15
= 3000 cm
≈ 30 metres
Therefore, Option (B) will be the answer.
Describe how the shape moves to get from it's position in each frame to the next. Select all ways the rectangle could have been rotated to get from fame 1 to fame 2.
Answer:
40 DEGREES COUNTERCLOCKWISE
140 DEGREES CLOCKWISE
Step-by-step explanation:
To get from frame one to frame two you can either rotate the object in a clockwise or anticlockwise direction.
We can use the edges of the rectangle to monitor the degree with which it is rotated.
If we rotate in a clockwise direction, it means that we are rotating from the left to the right; that is in the direction of the clock. If we are turning this way, we would have to turn the rectangle through 140 degrees to get it into frame 2's position
If we are rotating in the anticlockwise direction (against the direction of the clock) we are turning it from the right to the left. We will be turning it by only 40 degrees to get it into frame 2's position

Subtract 9 from 20 to get 11.
[tex]11=5p+12[/tex]
Swap sides so that all variable terms are on the left hand side.
[tex]5p+12=11[/tex]
Subtract 12 from both sides.
[tex]5p=11-12[/tex]
Subtract 12 from 11 to get −1.
[tex]5p=1[/tex]
Divide both sides by 5.

1) (5n - 5)(4n - 4)
Answer:
20n² - 40n + 20
Step-by-step explanation:
(5n - 5)(4n - 4)
= 5n(4n) + 5n(-4) - 5(4n) - 5(-4)
= 20n² - 20n - 20n + 20
= 20n² - 40n + 20
Another way to do this:
(5n - 5)(4n - 4)
= 5(n - 1) * 4(n - 1)
= 20(n - 1)(n - 1)
= 20(n - 1)²
= 20(n² - 2n + 1)
= 20n² - 40n + 20

Write 15^-6 using a positive exponent
Answer:
[tex]\frac{1}{15^{6}}[/tex]
Step-by-step explanation:
If you see a negative sign in the power, you will place the number and power over 1:
15^-6 = 1/(15^6)
[tex]\frac{1}{15^{6}}[/tex]
Simplify. Solve 15^6:
15^6 = 15 * 15 * 15 * 15 * 15 * 15 = 11,390,625
1/11,390,625 is your simplified answer.
However, note that you are solving for a positive exponent. Your answer will be:

The line m has a slope of 3/4 and passes through the point (-2, 1). Show that the point (82, 63) does or does not
lie on line m. Justify your answer.
Answer: It does not lie on the line m.
Step-by-step explanation:
First using the slope and the point find an equation in slope intercept form and plot in the coordinates (82,63) to see if it fits. If it fits then it lies on line m and if doesn't then it doesn't like on line M.
The slope intercept formula is y = mx +b where m is the slope and b is the y-intercept, so we need to use the coordinates (-2,1) to find the y-intercept.
Plot the coordinates and the slope into the formula to solve for b.
1 = 3/4(-2) + b
1 = -6/4 + b
+6/4 +6/4
b = 10/4
y = 3/4x + 10/4
63 = 3/4(82) + 10/4
63 = 64

What is the sum of 23/25 + 9/30
Answer:
61/50
Step-by-step explanation:
1*a = a
1 = b/b
then:
23*25 * 1 = (23/25)(12/12) = (23*12)/(25*12) =276/300
9/30 *1 = (9/30)(10/10) = (9*10)/(30*10) = 90/300
then:
(23/25) + (9/30) = (276/300) + (90/300)
= (276+90)/300
= 366/300
= 122/100
= 61/50
The addition of the fraction 23/25 + 9/30 is equal to 61/50.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
'a/b' of a quantity means that quantity is first divided in 'b' parts, and then mutiplied by 'a', or,
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
1*a = a
1 = b/b
then:
23*25 * 1 = (23/25)(12/12)
= (23*12)/(25*12) =276/300
9/30 *1 = (9/30)(10/10)
= (9*10)/(30*10) = 90/300
Now add the terms;
(23/25) + (9/30) = (276/300) + (90/300)
= (276+90)/300
= 366/300
= 122/100
= 61/50
Therefore, the addition of the fraction 23/25 + 9/30 is equal to 61/50.

Answer:
m = 1 (the slope is 1/1) b = -4 (the y-intercept is (0,-4))
Step-by-step explanation:
First, you have to plot a point at the y-intercept (0,-4). Then go up once and to the right once (since the slope is 1/1). Keep doing this as much times as you want and connect the dots to form a line. See image below.

Un terreno A, tiene un largo de 120 m. Y un ancho de 200 m. . Si es 3 veces más largo y 4 veces más ancho que el terreno B. ¿Cuál es el área del terreno B?
Answer:
El área del terreno B es 2000 m.
Step-by-step explanation:
Tenemos que el terreno A es:
[tex]L_{A}[/tex]: largo = 120 m
[tex]A_{A}[/tex]: ancho = 200 m
Y que el terreno B es:
Largo:
[tex] L_{A} = 3L_{B} [/tex]
[tex] L_{B} = \frac{L_{A}}{3} = \frac{120 m}{3} = 40 m [/tex]
Ancho:
[tex] A_{A} = 4A_{B} [/tex]
[tex] A_{B} = \frac{A_{A}}{4} = \frac{200}{4} = 50 m [/tex]
Entonces, asumiendo que el terreno es un rectángulo, el área del terreno B es:
[tex] a_{B} = L_{B}*A_{B} = 40 m*50 m = 2000 m [/tex]
Por lo tanto, el área del terreno B es 2000 m.

what are the prime factorization of 25
Answer:
25 = 5^2
Step-by-step explanation:
Factor the following integer:
25
Hint: | Is 25 divisible by 2?
25 is not divisible by 2 since 25 is odd and 2 is even:
25 = 25 (25 is not divisible by 2)
Hint: | Is 25 divisible by 3?
The sum of the digits of 25 is 2 + 5 = 7, which is not divisible by 3. This means 25 is not divisible by 3:
25 = 25 (25 is not divisible by 2 or 3)
Hint: | Is 25 divisible by 5?
The last digit of 25 is 5, which means 25 is divisible by 5:
25 = 5 5:
25 = 5×5 (5 is not divisible by 2 or 3 since 25 is not)
Hint: | Now try to factor 5. Is 5 prime?
No primes less than 5 divide into it. Therefore 5 is prime:
25 = 5×5
Hint: | Express 25 as a prime power.
There are 2 copies of 5 in the product:

Answer:
Start with the parent function y=1/x^2.
Add 3 to x in the denominator, because the graph is shifted left 3. Add 1 to the fraction, because the graph is shifted up 1 unit.
Step-by-step explanation:
When a function is transformed, it means the function is either rotated, dilated, rotated or translated.
The equation of the function whose graph is sketched is:
[tex]f(x) = \frac{1}{(x + 3)^2} + 1[/tex]
The parent function is an inverse function of the form:
[tex]y = \frac 1{x^2}[/tex]
The parent function is shifted in two ways.
3 units left1 unit upWhen a function is shifted to the left, the rule is:
[tex](x,y) \to (x + h,y)[/tex]
Where:
[tex]h \to[/tex] number of units.
So, we have:
[tex](x,y) \to (x + 3,y)[/tex]
The function becomes
[tex]y' = \frac{1}{(x + 3)^2}[/tex]
When a function is shifted up, the rule is:
[tex](x,y) \to (x ,y+b)[/tex]
Where:
[tex]b \to[/tex] number of units.
So, we have:
[tex](x,y) \to (x ,y+1)[/tex]
The function becomes
[tex]y'' = \frac{1}{(x + 3)^2} + 1[/tex]
So, the graph of the function in the given graph (see attachment) is:
[tex]f(x) = \frac{1}{(x + 3)^2} + 1[/tex]
