The planet Mars has two moons – Phobos and Deimos. Phobos has a mass of 10.8 × 1015 kilograms, and Deimos has a mass of 2.0 × 1015 kilograms. How much greater is the mass of Phobos than the mass of Deimos?
Answers
Answer:
mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.
Step-by-step explanation:
The planet Mars has two moons Phobos and Deimos.
Mass of Phobos = 10.8 × 10¹⁵ Kilograms
Mass of Deimos = 2 × 10¹⁵ Kilograms
So the difference in the masses of the moons
= 10.8 × 10¹⁵ - 2 × 10¹⁵
= (10.8 - 2) × 10¹⁵
= 8.8 × 10¹⁵ Kilograms
Therefore, mass of Phobos is 8.8 × 10¹⁵ Kilograms greater than mass of Deimos.

The volume of a sphere is given by:
V = (4/3) * (pi) * (r ^ 3)
Where,
r: sphere radio
Substituting values we have:
V = (4/3) * (3.14) * ((10/2) ^ 3)
V = 523.3333333
Rounding the nearest whole number we have:
V = 524 m ^ 3
Answer:
option 1
V = 524 m ^ 3
Question 2:
The area of a sphere is given by:
V = (4) * (pi) * (r ^ 2)
Where,
r: sphere radio
Substituting values we have:
V = (4) * (3.14) * ((15/2) ^ 2)
V = 706.5
Rounding the nearest whole number we have:
V = 706.5 yd ^ 2
Answer:
V = 706.5 yd ^ 2

The perimeter of the rectangle is:
P = 136ft
How much fencing will he need?
For a rectangle of length L and width W the perimeter is:
P = 2*(L + W)
And for a square of side length S, the perimeter is:
P' = 4*L
The length of the rectangle is:
L = 34ft + x
The width is W = x
For the square we have the side length S = x
Here we know that the perimeter of the rectangle is twice the perimeter of the square, then:
2*(W + L) = 2*(4*S)
Replacing these variables in terms of x, we get.
2*(x + 34ft + x) = 2*(4*x)
4x + 68ft = 8x
68ft = 8x - 4x = 4x
68ft/4 = x = 17ft
Then the perimeter of the rectangle is:
P = 2*(34ft + 17ft + 17ft) = 136ft

For the function h(x) = 6 - X the value of (hoh)(10) is 10.
What is a function?
A relation is a function if it has only One y-value for each x-value.
The given function is h(x) = 6 - X
We have to find the value of (hoh)(10)
The composite function (hoh)(10) can be written as h(h(10))
h(h(10))
Plug in the value 10 in place of x
=h(6-10)
=h(-4)
Now let us find h(-4)
=6-(-4)
=6+4
=10
Hence, for the function h(x) = 6 - X the value of (hoh)(10) is 10.

Answer:
The test statistic is -2.5
Yes, I can reject the null hypothesis at 5% significance level.
Step-by-step explanation:
Null hypothesis: The average number of sardines in a can is 9.75
Alternate hypothesis: The average number of sardines in a can is greater than 9.75
Test statistic (z) = (sample mean - population mean) ÷ sd/√n
sample mean = 9.75
population mean = 10
sd = 1
n = 100
z = (9.75 - 10) ÷ 1/√100 = -0.25 ÷ 0.1 = -2.5
The test is a one-tailed test. At 5% significance level, the critical value is 1.645
Conclusion:
Reject the null hypothesis because the test statistic -2.5 is less than the critical value 1.645

The interest is computed from
... I = Prt
where P is the principal amount ($569), r is the rate (0.045) and t is the time in years (250/360).
... I = $569×0.045×250/360 ≈ $17.78
Please note that time is not rounded. Rather, the exact value (25/36) is used in the calculation. The only rounding of any number is done at the end, where the amount is rounded to the nearest cent. (Your text authors should know this.)
_____
If you follow the problem instructions (which Valerie's lender will not do), the interest is calculated as ...

Note the rounding of intermediate numbers (time) introduces an error of about $0.11 in the answer.
