8 times because you take 4 times 2 and get 8
Reasoning:
There are 2 outcomes if you flip only one coin (H or T).
There are 2^2 = 2*2 = 4 outcomes if you flip two coins (HH, HT, TH, TT).
There are 2^3 = 2*2*2 = 8 outcomes if you flip three coins.
There are 2^4 = 2*2*2*2 = 16 outcomes if you flip four coins.

Given: circle k(O), m∠A=(x+45)°, m KE =(x+20)°, m EW =(3x)° Find: m KW . HELP ASAP WILL GIVE BRAINLIEST!
Answer:
160°
Step-by-step explanation:
We can use the central angle theorem for this. It says that an angle inscribed in a circle (on the circumference) measured half of the arc it intercepts (by 2 points on the circumference of the circle).
that would mean that Angle KAW is half of measure of Arc KW. Thus we can write:
m∠A = 0.5 (arc KE + arc EW)
x+45 =0.5 (x+20+3x)
x+45 = 0.5(4x+20)
x+45 = 2x + 10
45 - 10 = 2x - x
Thus, x = 35
Since Arc KW = Arc KE + Arc EW and x = 35, we can say:
Arc KW = x + 20 + 3x = 35 + 20 + 3(35) = 160°
The value of the arc KW subtended from the center of circle O is 160°.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the circle O:
m KW = m KE + m EW (angle addition postulate)
m KW = (x + 20) + (3x)
m KW = 4x + 20
m KW = 2m∠A (angle subtended from center)
4x + 20 = 2(x + 45)
x = 35
m KW = 4(35) + 20 = 160°
The value of the arc KW subtended from the center of circle O is 160°.

Use the provided ruler suppose you re-create the drawing so I had a scale of 1 cm to 4 cm in length and width of the new scale drawing be
To recreate a drawing on a new scale of 1 cm to 4 cm, simply multiply the original dimensions by the scale factor of 4.
Explanation:If you are given a drawing and you want to recreate it on a new scale where 1 centimeter (cm) in the original equals to 4 centimeters in the new drawing, then you simply have to multiply the dimensions of the original by 4. Suppose the original drawing is 2 cm in length and 3 cm in width. Then the new length would be 2 cm * 4 = 8 cm and the new width would be 3 cm * 4 = 12 cm. Remember this is a general concept and can be applied to all dimensions of the drawing. It's a basic concept in proportion and scale factor.

Step-by-step explanation: 2/6 is not equal to 2/3. Find common denominators. The common denominator would be 6. So multiply each number in 2/3 by 2. You will get 4/6. 4/6 is not equal to 2/3.
there are four students in each small reading group there are 24 students in all.
how many reading groups are there
Answer:
6
Step-by-step explanation:
24 / 4 = 6
Final answer:
The number of reading groups can be determined by dividing the total number of students, which is 24, by the number of students in each group, which is 4. The calculation is 24 ÷ 4, resulting in 6 reading groups.
Explanation:
To find the number of reading groups, we can use a simple division operation because we are dividing a larger group of items (students) into smaller equal-sized groups. In this case, we have 24 students and want to find out how many groups of 4 students we can create from that total.
Here's the step-by-step explanation:
Identify the total number of students, which is 24.
Identify the number of students in each reading group, which is 4.
Divide the total number of students by the number of students in each group: 24 ÷ 4 = 6.
Therefore, there are 6 reading groups.

Answer:
x = 5 x = 1
Step-by-step explanation:
−3|x − 3| = −6
Divide each side by -3
−3/-3|x − 3| = −6/-3
|x − 3| = 2
An absolute value is equal to a positive and negative solution
x-3 =2 and x-3 = -2
Add 3 to each side
x-3+3 = 2+3 x-3+3 = -2+3
x = 5 x = 1
use the substitution method to slove the system of equations choose the correct ordered pair x+y=11 -x=-y-10
Answer:
(10, 1)
Step-by-step explanation:
-x = -y - 9 has already been solved for -x. Multiply every term of this equation by -1 to obtain x = y + 9.
Now substitute y + 9 for x in the first equation. We get:
(y + 9) + y = 11, or, after combining the y terms, 2y = 2.
Solving for y, we get y = 1.
Subbing 1 for y in the first equation results in: x + 1 = 11.
This yields x = 10.
Thus, the solution is (10, 1).

what is the height and length of a rectangular box with a volume of 6x^2-600 with a width of 6
Answer:
(x+10) and (x-10)
Step-by-step explanation:
The volume of a rectangular box is defined as
Volume = width*height*length
In this case
Volume = 6x^2-600 = 6*(x^2 - 100)
And we also know,
Volume = (6)*height*length
So,
6*(x^2 - 100) = (6)*height*length
This means that
height*length = (x^2 - 100)
height*length = (x+10)*(x-10)
