If the spider rotates 135 degrees at each step, the number of degrees she rotate in total to create the eight-pointed star is: 1080 degrees
How to find the number of rotation?Since we were told that the spider creates an eight-pointed star by rotating around a central point, which implies she makes 8 rotations to create the star.
So, each rotation is 135 degree, now let find the number of rotation by multiplying the number of rotations which is 8 by the number of degrees per rotation 135.
Number of rotation = 8 × 135
Number of rotation = 1080 degrees
Therefore, the spider rotates 1080 degrees in total to create the eight-pointed star.

If a + b = 20 and ab = 75, find the value of a? + b2.
Answer:
a² + b² = 250
Step-by-step explanation:
Given
a + b = 20 ( square both sides )
(a + b)² = 20² , that is
a² + b² + 2ab = 400 ( substitute ab = 75 )
a² + b² + 2(75) = 400
a² + b² + 150 = 400 ( subtract 150 from both sides )
a² + b² = 250

What is the quotient of -3/8and-1/3
Answer:
i think the answer is 1 1/8 (or 1.125)
Step-by-step explanation:
1. -3/8 / -1/3 = 3/8 * 3/1 = 9/8
2.Simply this improper fraction to a mix number
9/8 = 1 1/8 (and since 1 is going into the 9,8 it cannot be reduced further)
3rd 1 1/8 is recognized as 1.125
Write an equation that represents the line
he general equation of a line is y = mx+b
m is the slope of the line that you can figure out using the equation: m = (y2-y1)/(x2-x1)
m = (4-2)/(4-1) = 2/3
y = 2/3x+b and you can use either point given to find b:
1) 4 = 2/3(4)+b => b = 4-8/3 = 4/3
2) 2 = 2/3(1)+b => b = 2-2/3 = 4/3
The equation becomes: y = 2/3 x + 4/3
(58*13)15 - 20+ 48^2
Answer:
13,594
Step-by-step explanation:
Parentheses
Exponets
Multiply
Divide
Add
Substract
You follow the list in order so you would do the parentheses first and then the exponets and so forth. This is how I got my answer:
(58*13) * 15 - 20 + 48^2 - solve what's in the parentheses first
754 * 15 - 20 + 48^2 - then solve the exponet
754 * 15 - 20 + 2304 - next you solve the rest of the problem from left to right, in that case, I would multiply
11310 - 20 + 2304 - then I would subtract
11290 + 2304 - finally i would add
13594 - This would be my answer
I hope this helps :) Have a nice day!

Step-by-step explanation:
Factor the following:
-32 x y + 12 2 y + 8 y
12×2 = 24:
24 y - 32 x y + 8 y
Grouping like terms, -32 x y + 24 y + 8 y = (24 y + 8 y) - 32 x y:
(24 y + 8 y) - 32 x y
24 y + 8 y = 32 y:

Calculate the product above and give your answer in scientific notation.
I think you meant to write
(2 × 10⁶) × 0.00009
First, convert 0.00009 to scientific notation:
0.00009 = 9 × 10 ⁻⁵
Then
(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)
… = (2 × 9) × (10⁶ × 10 ⁻⁵)
… = 18 × 10¹
… = 1.8 × 10²

Carolina and Patricia received their Christmas bonus and decided to use this weekend to buy their Christmas gifts .
Carolina decided to take advantage of the Great Winter Sale in Liverpool that offers discounts of 50% + 20%.
Patricia went to the mall and took advantage of the boutique discount that offers discounts of 70%.
They both bought 3 items with a total listing price of $120. At the end of their purchase rounds, they will have coffee with their friend Cristina and tell her about the offers they found. Based on their experiences, Cristina must decide where she will do her shopping.
Analyze this situation and think,
Where would you recommend Cristina to do her shopping? What is the final price paid on each establishment?
Applying what you have seen in your math classes, what where your calculations and how you can relate it to composition of functions.
Answer:
I would recommend Christina to do her shopping at any of those 2 places because they both have a discount of 70%. The final price paid on each establishment was $36.
120*0.7 = 84
120 - 84 = 36
Step-by-step explanation:
Carolina has a discount of 50%+20% which is the same as a discount of 70%, and Patricia had a discount of also 70%, so they both had the same discounts.
