which one does it equal to? what break 80 into two equal pieces?
Answer:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.
put these numbers in order least to greatest 1 1/3, -5/6, 0, -2/3, -1
Answer:
-1, -5/6, -2/3, 0, 1 1/3
Step-by-step explanation:
Answer:
-1, -5/6, -2/3, 0, 1 1/3.
Step-by-step explanation:
1 1/3, -5/6, 0, -2/3, -1
The easiest way is to convert them to decimal fractions first:
= 1.333.... , - 0.8333... , 0, -0.666.... , - 1
So in ascending order they are
-1, -0.833.., -0.666... , 0 , 1.333.....
= -1, -5/6, -2/3, 0, 1 1/3.

How many atoms of H is in 300g H2O
Answer:
[tex]1.003*10^{25}[/tex]
Step-by-step explanation:
We'll be using Avogadro's number which defines the amount of atoms in a mole.
To find the mole amount, we use the atomic mass to find the molar mass because the atomic mass represents how many grams are in a single mole of any element
2 Hydrogen atoms have an atomic mass of 2.016 g
1 Oxygen atom has an atomic mass of 15.999 g
Adding these two numbers gives us H2O's molar mass, which is 18.015 g/mol (grams per mole).
Now we take the supplied mass of 300g and divide it by the mm (molar mass) to find the amount of moles we have. 300/18.015 = 16.653
We have 16.653 moles in 300g of H2O.
Now we have to multiply 16.653 by Avogadro's number, [tex]6.022 * 10^{23}[/tex]
This gives us: [tex]1.003*10^{25}[/tex]

Answer:
Z = 63º
Step-by-step explanation:
X = 180 - 61 - 31 = 88º Angles in a triangle add to 180º
Y = 180 - X = 180 - 88 = 92º Angles in a straight line add to 180º
Z = 180 - 25 - Y = 180 - 25 - 92 = 63º Angles in a triangle add to 180º
So Z = 63º

If you roll an 8. 5-by-11-inch piece of paper into a cylinder by bringing the two longer sides together, you get a tall, thin cylinder. If you roll an 8. 5-by-11-inch piece of paper into a cylinder by bringing the two shorter sides together, you get a short, fat cylinder. Which of the two cylinders has the greater volume?
The cylinder which would have the greater volume is that in which the two shorter sides together, you get a short, fat cylinder.
Which cylinder has the greater volume between the two?It follows from the task content that the cylinder is made from the same paper dimensions.
On this note, it follows that when the shorter sides are joined, the longer side represents the height of the cylinder formed.
Consequently, the shorter cylinder has the greater volume.

Which is true for
the vertex?
A. A vertex is any angle.
B. A vertex is the end point of a single line segment.
C. A vertex is a point that describes the corner or
intersection of an angle.
Answer:
C.
Step-by-step explanation:
It is the corner or a point where line segments meet.
Hi!
Your answer is C.
The vertex is the point where two different rays meet, forming an angle.
It can also simply be the point where 2 straight lines simply meet.
Option A is NOT correct because a vertex is not angle, it is a part of an angle.
Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

Step-by-step explanation:
Earthquakes are measured by the Richter scale and demonstrated by the formula R = log(A) where A measures the amplitude of the earthquake wave and A, is the amplitude of the smallest detectable wave (or standard wave). An earthquake is measured with a wave amplitude 1800 times as great as a standard wave. What is the magnitude of this earthquake using the Richter scale? Round to the nearest tenth.
Answer:
3.22
Step-by-step explanation:
log(18×100)
log18+log100
1.22+2
3.22
The magnitude of this earthquake using the Richter scale is approximately 3.3 (rounded to the nearest tenth).
How to determine the magnitude of the earthquakeTo calculate the magnitude of the earthquake using the Richter scale, we can use the formula
R = log(A/A₀),
where
A is the amplitude of the earthquake wave, and
A₀ is the amplitude of the standard wave.
If the earthquake wave's amplitude is 1800 times as great as the smallest detectable wave, this means A/A₀ = 1800.
Therefore, the magnitude of the earthquake (R) would be:
R = log(1800)
Let's calculate it:
R ≈ log₁₀(1800) ≈ 3.255
So, if we round this to the nearest tenth, the earthquake's magnitude on the Richter scale would be approximately 3.3.

Which measurements are correct? round side lengths to the nearest hundredth. check all that apply. m∠a = 57° m∠b = 15° c ≈ 10.89 ft h ≈ 8.09 ft h ≈ 31.28 ft
The correct measurements of the surveyors movement from all the options are; m∠b = 15° and h ≈ 31.28 ft
What are the correct elevation measurements?
From the image attached, we see that;
A surveyor found the angle of elevation from the ground to the top from a point = 33°
Now, the surveyor moves 20 ft towards the building and the angle of elevation becomes 48°. This means that ∠A and 48° are supplementary to each other.
Thus;
∠A + 48° = 180°
∠A = 180 - 48
∠A = 132°
From sum of angles in a triangle;
∠B + 33° + 132° = 180°
∠B = 180 - 165°
∠B = 15°
Using sine rule, we know that;
sin 33/C = sin B/20
Thus;
sin 33/C = sin 15/20
Solving for C gives;
C = 42.22
From trigonometric ratios, h/c = sin 48
h = 42.22 sin 48
h = 31.28 ft

What are the solutions of the quadratic equation 0 = 4(x - 3)2 - 16?
O 2 and -2.5
O 2 and 2.5
О 1 and -5
0 1 and 5
Answer:
x = 5, x = 1
Step-by-step explanation:
The quadratic equation 0 = 4(x - 3)2 - 16.
Using binomial theorem, (a - b)2 = a2 - 2ab + b2 to expand (x - 3)2.
0 = 4(x2 - 6x + 9 ) - 16.
Using distributive property to multiply 4 by x2 - 6x + 9.
0 = 4x2 - 24x + 36 - 16.
Subtract 16 from 36 to get 20.
0 = 4x2 - 24x + 20.
4x2 - 24x + 20 = 0.
Divide both sides by 4.
x2 - 6x + 5 = 0.
To solve the equation, factor and rewrite as x2 + ax + bx + 5
a + b = -6, ab = 1(5) = 5.
a = -5, b = -1.
Rewriting x2 - 6x + 5 as
(x2 - 5x) + (-x + 5)
Factor x in the first and -1 in the second group.
x(x - 5) - (x - 5)
Factor out common term
(x - 5)(x - 1)
By solving the above, we get
x = 5, x = 1

A bag contains 9 tiles, one for each letter in the word HAPPINESS. You
choose a tile at random. What is the probability that you choose a tile with
the letter S? What is the probability that you choose a tile with a letter other
than P?
Answer:
shown below
Step-by-step explanation:
9 different possible tiles to choose, but there are duplicates of two types of tiles. Out of 9 tiles, two of them are S. Therefore, the probability you choose an S is 2/9 (however much percent that is).
You'd reverse the math for letters other than P:
Out of 9 tiles, two of them are P. 9 minus 2 is seven. Seven out of 9 characters are not the letter P. Therefore, the probability you choose any letter other than P is 7/9 (however much percent that is).
