Answer:
6 markers
Step-by-step explanation:
1) Find the number of red markers
Firstly, we know that Ms. Peters has a total of 36 markers. There are 3 colours within these 36 markers. Because she has an equal number of each colour, divide 36 by 3 to find the number of red markers.
36÷3=12
Therefore, Ms. Peters has 12 red markers.
2) Find the number of red markers in each group
Ms. Peters then divides the red markers into 2 equal groups. Because we now know that there are 12 red markers, divide 12 by 2 to find this number.
12÷2=6
Therefore, there are 6 red markers in each group.
I hope this helps!

PLEASE HELP
Answer:
A) y=3x+1
Step-by-step explanation:
Use the formula y=mx+b
m is the slope and b is the y intercept
the graph starts on 1 on the y axis so you replace 1 for b
the slope goes up 3 and over one, giving the fraction 3/1 or just 3. so you replace 3 for m.
Factor the polynomial: x^7 - x^5
Select one:
a. x^5(1 - x)
b. x^5(1 - 2x)
c. x^5(x^2 - 2x)
d. x^5(x^2 - 1)
Answer:
d. x^5(x^2 - 1)
Step-by-step explanation:
x^7 - x^5
Factor out x^5
x^5(x^2−1)
Consider x^2−1. Rewrite x^2−1 as x^2−1^2. The difference of squares can be factored using the rule: a^2 - b^2 =(a−b)(a+b).
(x−1)(x+1)
Rewrite the complete factored expression.
x^5(x−1)(x+1)
Simplify.
(x^2 - 1)x^5
Swap terms to the left side.

Solve the following equation algebraically:
-16 = 16x?
How many solutions does this equation have? Explain.
a. -1 = x3; One solution because only -1 will satisfy the equation.
b. -1 = x2; No real solution because there is no real number that, when squared, produces -1.
c. 1= x?: Two solutions because the square root of 1 is positive 1 and negative 1.
d. 1=-x?: One solution because only -1 will satisfy the equation.

5/3
Answer:
the first one
Step-by-step explanation:
Hey There!
Look at the image for the rule of a 30- 60 - 90 triangle
x = 5
the hypotenuse would be x2 so 10
the longer leg would be x[tex]\sqrt{3}[/tex]
So the first triangle is the right answer
The first triangle in the figure is a 30°-60°-90° triangle.
What is a triangle?A triangle is a polygon with three sides and three angles.
Given are triangles, we need to see which of them are a 30°-60°-90° triangle,
So,
In a 30°60°-90° triangle, the side opposite the 30° angle (shortest side) is half the length of the hypotenuse.
So you have to choose one with 5 & 10.
Use the Pythagorean theorem to calculate the remaining side
a² + b² = c²
5² + b² = 10², so b² = 100-25 √b²=√75 so √(25)(3)
b= 5√3
Hence, the first triangle in the figure is a 30°-60°-90° triangle.

Find the length of the missing side.
Answer: i think 80 not sure tho i failed my last test
Step-by-step explanation:
Answer:
80 in
Step-by-step explanation:
Because this is a right triangle we can find the length of the missing side using the Pythagorean Theorem
Given the hypotenuse and one leg we do
[tex]c^2-b^2=a^2[/tex]
where c = hypotenuse and b = leg
[tex]82^2=6724\\18^2=324\\6724-324=6400\\\sqrt{6400} =80[/tex]
so we can conclude that the missing side length is equal to 80
