Answer:
The centroid is always between the orthocenter and the circumcenter. The distance between the centroid and the orthocenter is always twice the distance between the centroid and the circumcenter. In obtuse triangles, the circumcenter is always outside the triangle opposite the largest....280 ml as a percentage of 140 l.
Answer:
280 ml as a percentage of 140 l is 0.2%
Step-by-step explanation:
Note that 1 liter = 1000 millilitersTo find a percentage of a number divide the number by the total and multiply the quotient by 100%∵ There is an amount of 280 ml
∵ The total amount is 140 l
→ Change the liter to milliliters using the 1st point above
∴ 140 l = 140 × 1000 = 140000 ml
∴ 140 l = 140,000 ml
→ Now divide the amount by the total, then multiply the quotient by 100%
∵ 280 ÷ 140,000 = [tex]\frac{1}{500}[/tex]
∵ [tex]\frac{1}{500}[/tex] × 100% = 0.2%
∴ 280 ml as a percentage of 140 l is 0.2%

What is the standard deviation? Round your answer to two decimal places. s_x\approxs x ≈s, start subscript, x, end subscript, approximately equals \text{kg}kgstart text, k, g, end text
Answer:
The standard deviation of the weight, σ, is approximately 4.73 kg
Step-by-step explanation:
The weights of the six puppies are;
[tex]x_i[/tex] = 1, 2, 7, 7, 10, and 15
The number of puppies, n = 6
Therefore, we have;
The mean = μ = ∑x/n = (1 + 2 + 7 + 7 + 10 + 15)/6 = 7
The standard deviation, σ, is given as follows;
[tex]\sigma =\sqrt{\dfrac{\sum \left (x_i-\mu \right )^{2} }{n}}[/tex]
By substituting, we have;
[tex]\sigma =\sqrt{\dfrac{ \left (1-7 \right )^{2} + \left (2-7 \right )^{2} + \left (7-7 \right )^{2} + \left (7-7 \right )^{2} + \left (10-7 \right )^{2} + \left (15-7 \right )^{2} }{6}}[/tex]
Simplifying gives;
[tex]\sigma =\sqrt{\dfrac{ \left (-6 \right )^{2} + \left (-5 \right )^{2} + \left (0 \right )^{2} + \left (0 \right )^{2} + \left (3 \right )^{2} + \left (8 \right )^{2} }{6}} =\sqrt{\dfrac{ 36 + 25 + 0 +0+ 9 + 64 }{6}}[/tex]
[tex]\sigma =\sqrt{\dfrac{ 134 }{6}} = \sqrt{\dfrac{67}{3} } \approx 4.72582[/tex]
The standard deviation of the weight, σ ≈ 4.73 kg to two decimal places.

solve for n. n/-5= 7
Answer:
n = -35
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define equation
n/-5 = 7
Step 2: Solve for n
Multiply both sides by -5: n = -35Step 3: Check
Plug in n into the original equation to verify it's a solution.
Substitute in n: -35/-5 = 7Divide: 7 = 7Here we see that 7 does indeed equal 7.
∴ n = -35 is a solution to the equation.

Answer:
The answer is B
Step-by-step explanation:
Mke y the subject of the formula.
w=x^2-2yz
Answer:
W = x^2 - 2yz / - w
0 = x^2 - 2yz - w / +2yz
2yz = x^2 - w // 2z
y = (x^2 -w ) / 2z

The length of a cell phone is 1.21.2 inches and the width is 4.64.6 inches. The company making the cell phone wants to make a new version whose length will be 1.141.14 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
Answer:
The width of the new phone will be 4.37 inches
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value.
The original length of a cell phone was L=1.2 inches and the original width was 4.6 inches.
A new version of the cell phone is to be released with proportional dimensions with respect to the original cell phone.
We are given the length of the new phone L'=1.14 inches. The ratio of the lengths is 1,2/1.14=1.053.
The new width should be W'=4.6/1.053=4.37 inches
The width of the new phone will be 4.37 inches

Given m|n, find the value of x.

(x-17)
(5x-1)
>m
please help me
=======================================================
Explanation:
The information that m || n is not needed or used, so I'm not sure why your teacher put that in there.
The angles shown are a linear pair. They are adjacent and they are supplementary. They form a straight angle.
Supplementary angles add to 180.
(x-17)+(5x-1) = 180
x-17+5x-1 = 180
(x+5x)+(-17-1) = 180
6x-18 = 180
6x = 180+18
6x = 198
x = 198/6
x = 33
---------
Extra info:
if x = 33, then,
x-17 = 33-17 = 165x-1 = 5*33-1 = 165-1 = 164Adding the angles gives 16+164 = 180 which helps confirm our answer.

Answer:
D. m = -15/1
Step-by-step explanation:
Slope Formula-
m = (y2-y1)/(x2-x1)
Using two random points-
(-1, 13) (0,-2)
-1 = x1
13 = y1
0 = x2
-2 = y2
m = (-2 - 13)/(0-(-1))
m = -15/1
