The mass of a gold atom is 3.29 x 10-22 grams. The mass of a helium-4 atom is
6.65 x 10-24
grams. How many times greater is the mass of a gold atom than the
mass of a helium-4 atom? Write your answer in standard notation, rounding to the
nearest tenth.
Answer:
um, I checked the questions you asked and we have the same questions, I think we might be in the same school lol
There are 4.9 x 10³ times greater is the mass of a gold atom than the mass of a helium-4 atom.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
The mass of a gold atom is 3.29 x 10⁻²² grams.
And, The mass of a helium-4 atom is, 6.65 x 10⁻²⁴ grams.
Hence, The amount of greater is the mass of a gold atom than the mass of a helium-4 atom is,
⇒ 3.29 x 10⁻²² / 6.65 x 10⁻²⁴
⇒ 0.49 x 10²
⇒ 4.9 x 10³
Thus, There are 4.9 x 10³ times greater is the mass of a gold atom than the mass of a helium-4 atom.

The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction.
What are the coordinates of the new point?
Answer:
(-6, 4)
Step-by-step explanation:
Given the coordinate points (-3,1). If The point (-3,1) is moved 3 places in the negative y direction and 2 places in the positive x direction the required coordinate will be expressed ss;
X' = (-3-3, 1+3)
X = (-6, 4)

[tex]x + y = 0 \\ y = {x}^{2} + 2xy[/tex]
can any one tell this answer with dafination and all steps
Answer:
(1, -1)
Step-by-step explanation:
Given the expression
x+y = 0 .....1
y = x²+2xy ....2
From equation 1, x = -y
Substitute into 3
y = x²+2xy
y = (-y)²+2(-y)y
y = y²-2y²
y = -y²
1 = -y
y = -1
Since x = -y
x = -(-1)
x = 1
Hence the required solution is (1, -1)

9514 1404 393
Answer:
A. 201 cm³
Step-by-step explanation:
To find the volume, we need to know the length of the prism and the area of the triangular base.
We can find the area of the triangular base a couple of ways. Since we are given some angles, the convenient way will be to make use of those angles.
The triangular base is isosceles. For our purpose, we assume that means AB = BC. If we define point M as the midpoint of AC, then triangle BMC is a right triangle with a base of (9 cm/2) = 4.5 cm.
The side BC can be found from the trig relation ...
cos(∠BCA) = CM/BC
BC = CM/cos(∠BCA) = (4.5 cm)/cos(50°) ≈ 7.00
Then the area of the end triangle ABC is ...
base area = (1/2)(AC)(BC)sin(50°)
base area = (1/2)(9 cm)(7 cm)sin(50°) ≈ 24.133 cm²
__
The length CF can be found from the relation ...
tan(40°) = EF/CF
CF = EF/tan(40°) = (7.00 cm)/tan(40°) ≈ 8.343 cm
Then the volume of the prism is ...
V = Bh
V = (24.133 cm²)(8.343 cm) ≈ 201 cm³
The volume of this isosceles triangular prism is about 201 cm³.
Answer:
A. 201 cm³ is the answer.

Lilly sells 4 boxes of cookies in 60 minutes, at this rate how long will it take her to sell 10 boxes?
Answer:
150 minutes ! 60/4 multiplied by 10!
Step-by-step explanation:
Answer:
Step-by-step explanation:To find out how long it takes her to sell one box you see how many times 4 can go into 60 to get how long it takes to sell one box. So in this case it takes 15 minutes to sell one box. So you take 15 and multiply it by 10. 15 * 10= 150
60/4=15
15*10=150
So it takes 150 minutes to sell 10 boxes of cookies.

18) b = 90; c = 80; d = 100
Step-by-step explanation:
17)
2m = 70
m = 35
n + 70 + 70 + n = 360
2n + 140 = 360
2n = 220
n = 110
18)
b - 10 + b + 10 = 180
2b = 180
b = 90
b - 10 = c
90 - 10 = c
c = 80
b + 10 = d
90 + 10 = d
d = 100

Sheila is twice as old as Rita. In two years, Sheila will be four times as old as Rita was nine years ago. How old is each now?
Answer: (Sorry for not wording it correctly I had to reword it)
Step-by-step explanation: Let R be the current age of Rita. Let S be the current age of her son.
Rita is twice as old as her son.
=> R = 2S
In 4 years, R will be 4 times as old as S was 9 years ago
=> R + 4 = 4 (S - 9)
Solve for R, and S:
=> R + 4 = 4 (S - 9)
=> (2S) + 4 = 4(S - 9)
=> 2S + 4 = 4S - 36
=> 2S - 4S = -36 - 4
=> -2S = -40
=> S = 20
Find R:
=> R = 2S
=> R = 2(20)
=> R = 40
Therefore, Rita is 40, her son is 20.
Write a rule in function notation to describe the transformation that is a reflection across the x-axis.
Answer:
R(x, y) = (x, -y)
Step-by-step explanation:
When we have a reflection across some line, the distance between the original point and the reflected point to the line is invariant.
For a reflection around the x-axis, the x-value is invariant, then the only value that can change is the y-value.
So if we have a point like (4, 7)
Which is at a distance of 7 units to the x-axis, the only other point that is also at a distance of 7 units to the x-axis that has the same x-value is (4, -7)
Here we already can see the rule.
If we have a point (x, y), the reflection across the x-axis gives us the point (x. -y)
Then we can write this reflection as a function in the next way:
R(x, y) = (x, -y)
This means that if the input is the point (x, y), the output is the point (x, -y)
