the hydrogen atom contains a proton mass 1.67*10^-24g. An oxygen atom has a mass of about 2.66*10*-23g. About how many times as great is the mass of an oxygen atom than the mass of a hydrogen atom? Show your work.
Answers
Answer:
16.00 grams/mole Oxygen * (1 mole/6.022x1023 atoms) = 2.66 x 10-23 grams. Any slight differences are due to the accuracy used for the atomic.
Step-by-step explanation:
The mass of the oxygen atom is 15.9 times higher than the mass of the hydrogen atom.
What is an exponent?The number of times a number is multiplied by itself is referred to as an exponent.
Given that, the weight of the hydrogen atom is 1.67×10⁻²⁴ g and the mass of the oxygen atom is 2.66×10⁻²³g.
To find how many times as great the mass of the oxygen atom than the mass of a hydrogen atom is, divide the mass of the oxygen atom by the mass of the hydrogen atom:
(2.66×10⁻²³)/ (1.67×10⁻²⁴)
= 1.59 × 10⁻²³⁺²⁴
= 1.59 × 10
= 15.9
Hence, the mass of the oxygen atom is 15.9 times higher than the mass of the hydrogen atom.

What is Combination?An arrangement of objects where the order in which the objects are selected does not matter.
If Jason is going to watch all 4 movies back-to-back, then there are 4 options for the first movie, 3 options for the second movie (since one movie has already been watched), 2 options for the third movie, and 1 option for the fourth movie.
Therefore, the total number of different orders in which Jason can watch the movies is:
4 x 3 x 2 x 1 = 24

Step-by-step explanation:
the area of the triangles:
12*10 = 120
120/2 = 60
since there are 2 triangles of the same dimensions that make up the surface area 60 + 60 = 120
area of the rectangles:
13*14 = 182
since there are 2 rectangles of the same dimensions 182 + 182 = 364
The last rectangular:
10*14 = 140
add all areas:
120 + 364 + 140 = 624
13 x 14= 182 x 2= 364
354+120=484mm^2

The city is building a new roundabout in order to correct a traffic flow issue at some of its intersections. Due to safety regulations, the inner circle must have a diameter of 9 ft. When construction is complete, they plan to cover this area with grass. How much sod do they need to cover the inner circle of the roundabout?
Write a paragraph, following the RACE format, to explain how you calculate this answer.
Answers
Answer:
I don’t know
Step-by-step
StOp
The total sod needed to cover the inner circle of the roundabout is given by C = 28.27 feet
What is a Circle?A circle is a closed figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The circumference of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle.
The equation of circle is ( x - h )² + ( y - k )² = r²
For a unit circle , the radius r = 1
x² + y² = r² be equation (1)
Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )
Given data ,
Let the city be building a new roundabout in order to correct a traffic flow issue at some of its intersections
Now , the diameter of the inner circle be d = 9 feet
So , the radius of the inner circle , r = d/2
On simplifying , we get
The radius of the inner circle r = 4.5 feet
Now , the amount of sod do they need to cover the inner circle of the roundabout = circumference of the roundabout
The circumference of the circular roundabout C = 2πr
The circumference of the circular roundabout C = 2π ( 4.5 )
The circumference of the circular roundabout C = 9π feet
The circumference of the circular roundabout C = 28.27 feet
Hence , the amount of sod for the roundabout is 28.27 feet

In the figure, c ∥ d. What are the measures of ∠1 and ∠2?
Answers
1=105 degrees and 2=75 degrees
Answer:
∠ 1 = 105°, ∠ 2 = 75°
Step-by-step explanation:
∠ 2 and 75° are corresponding angles and are congruent, so
∠ 2 = 75°
∠ 1 and ∠ 2 are adjacent angles and sum to 180° , that is
∠ 1 + ∠ 2 = 180°
∠ 1 + 75° = 180° ( subtract 75° from both sides )
∠ 1 = 105°

Can someone please tell me if these triangles are similar or not, and why.
Answers
Answer:
No they are not similar.
Step-by-step explanation:
Because their angles are not the same. 1st triangle: 42-48-90 2nd triangle:58-32-90
Answer:
No, they are not similar.
Step-by-step explanation:
All the angles in a triangle add up to 180°. In both triangles, we already know two of the angles - 42° and 90° in one, 58° and 90° in the other.
Let's see if they match.
180 - 90 - 42 = 48
That's 48, not 58...
Let's check again with the other triangle.
180 - 90 - 58 = 32
48 does not equal 58.
32 does not equal 42.
Therefore, the two triangles are not similar.
