The table shows the values of two quantities for an astronaut on Earth and Earth's moon. Which of the following names the quantity and correctly explains why that represents the astronaut's mass? Quantity A, because it remains the same throughout Quantity B, because it is independent of other quantities Quantity B, because it changes with gravitational strength Quantity A, because it measures the force acting on the astronaut
Answers
Answer:
A.
Step-by-step explanation:
the answer is A. because in space, the whole thing is the same amount of density. except for the sun but the question says earth and moon. hop this helps!!! please give me brainliest answer!!!
Quantity A because it changes with gravitational pull.
Given that, the Astronaut's mass of quantity A on earth is 70 units and on the moon is 70 units.
The Astronaut's mass of quantity B on earth is 686 units and on the moon is 112 units.
What happens to an astronaut's mass in space?We can measure weight here on Earth, but not in the microgravity environment on the International Space Station. Mass plays a critical role in the activities and experiments performed by the astronauts. Mass does not change whether it is measured on Earth or the ISS.
Now, mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.
On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.
That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one-third that on earth.
Therefore, Quantity A because it changes with gravitational pull.

Express the following vector in the form v=v1i+v2j+v3k. 3u - v if u=(4,7,-3) and v=(2,-7,5).3u - v = ____ i + ____ j + _____ k.(Simplify your answers.)
Answers
Answer:
5i+14j-7kStep-by-step explanation:
Given the vectors u = (4,7,-3) and v=(2,-7,5), both vectors are 3-dimensional in nature and can also be rewritten as;
u = 4i+7j-3k and v = 2i-7j+5k
To get 3u-v, we will substitute the given vectors into the expression;
3u-v = 3(4i+7j-3k) - (2i-7j+5k)
open the parenthesis
3u-v = 12i+21j-9k - 2i + 7j - 5k
collect like terms
3u-v = (12i - 2i) + (21j + 7j) (-9k-5k)
3u - v = 10i+28j-14k
To simplify the answer, we will divide through by 2
3u - v = 10i/2+28j/2-14k/2
3u - v = 5i+14j-7k
Hence the simplified form of the expression is 5i+14j-7k
It is recommended that pregnant women over eighteen years old get 85 milligrams of vitamin C each day. A doctor is concerned that her pregnant patients are not getting enough vitamin C. So, she collects data on 45 of her patients and finds that the mean vitamin intake of these 45 patients is 81 milligrams per day with a standard deviation of 12 milligrams per day. Based on a level of significance of α = .02, test the hypothesis.H0 : u = 85H1 : u< 85n = 45sample mean = 81σ = 12z based on α = .02 = -2.05 ( if lessthan -2.05 we will reject the null hypothesis)Sample standard deviation = 12/√45 = 1.789z= x-u/σ(o sample) - 81-85/1.789 = -2.236-2.236is less than -2.05 so wereject the H0 : u = 85

Answer:
|Z| = 2.237 < 2.32 at 0.02 level of significance
Null hypothesis is accepted
Recommended that pregnant women not over eighteen years old get 85 milligrams of vitamin C each day
Step-by-step explanation:
Step(i):-
Given sample size 'n' = 45
Mean of the Population 'μ' = 85
Mean of the sample 'x⁻' = 81
Standard deviation of the sample 'σ' = 12 milligrams
Null Hypothesis: H₀:μ=85
Alternative Hypothesis: H₁:μ≠ 85
Step(ii):-
Test statistic
[tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{81 -85}{\frac{12}{\sqrt{45} } }[/tex]
Z = -2.237
Level of significance = 0.02
Z₀.₀₂ = 2.32
|Z| = 2.237 < 2.32 at 0.02 level of significance
Conclusion:-
Null hypothesis is accepted
Recommended that pregnant women not over eighteen years old get 85 milligrams of vitamin C each day

What is the solution to this system:
4x+9y=28
- 4x-y=-28
Answers
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
→Plug in 0 for y, into an equation:
-4x - 0 = -28
-4x = -28
x = 7

Answers
Answer:
x = 28°Step-by-step explanation:
From the question the figure above is a triangle.
The sum of angles in a triangle add up to 180°
To find the value of x add up all the angles and equate them to 180 to find the value of x
We have
50 + 2x + 3x - 10 = 180
5x + 40 = 180
5x = 180 - 40
5x = 140
Divide both sides by 5
We have the final answer as
x = 28°Hope this helps you

but will cost your family $1750 in airfare. How many nights will your family have to stay
in order for the vations to cost the same amount of money?
Answers
Answer:
Step-by-step explanation:
5 nights
The family have to stay 5 nights in order to cost the same amount of money.
Function in one variable:Let us consider that family is staying for x night.
Given that, Option A costs $479 per night and includes airfare in the cost.
So that, [tex]A(x)=479x[/tex]
Also Option B costs $129 per night but will cost your family $1750 in airfare.
So that, [tex]B(x)=129x+1750[/tex]
for the cost of same amount of money,
[tex]A(x)=B(x)\\\\479x=129x+1750\\\\479x-129x=1750\\\\350x=1750\\\\x=1750/350=5[/tex]
The family have to stay 5 nights in order to cost the same amount of money.

what is the solution to : 3(1/2 m - 3) =45
Answers
Answer:
[tex]m=36[/tex]
Step-by-step explanation:
We can solve for this equation by isolating [tex]m[/tex] on one side. To do this, we can "reverse" the equation.
[tex]3(\frac{1}{2}m - 3) = 45[/tex]
Let's divide both sides by 3.
[tex]3(\frac{1}{2}m-3)\div3 = 45\div3\\\\\frac{1}{2}m - 3 = 15[/tex]
Add 3 to both sides:
[tex]\frac{1}{2}m - 3 + 3 = 15 + 3\\\\\frac{1}{2}m = 18[/tex]
Multiply both sides by two (since [tex]\frac{1}{2}\cdot2=1[/tex])
[tex]\frac{1}{2}m \cdot 2 = 18 \cdot 2\\\\m = 36[/tex]
