ans b is the correct answer because
first we should have to multiply 1.4×10 power 6 which means 14000000 km
then we should divide with mars diameter which is 7000 km
14000000/7000km= 2× 10 power 3
2× 10 power 3
2×1000
therefore 2000 km is the ans

A 10-pound block of ice melts at a rate of 3% per hour. Find the weight of the block of ice after 1 day.
Answers
Answer:
The weight of the block of ice after 1 day is of 4.81 pounds.
Step-by-step explanation:
Equation for exponential decay:
The equation that models an amount after t hours, subject to exponential decay, is given by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal.
A 10-pound block of ice melts at a rate of 3% per hour.
This means that [tex]A(0) = 10, r = 0.03[/tex]
So
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]A(t) = 10(1 - 0.03)^t[/tex]
[tex]A(t) = 10(0.97)^t[/tex]
Find the weight of the block of ice after 1 day.
One day has 24 hours, so this is A(24).
[tex]A(24) = 10(0.97)^{24} = 4.81[/tex]
The weight of the block of ice after 1 day is of 4.81 pounds.
Please help!!!! Sine and cosine ratios
Answers
Answer: 40.9
Step-by-step explanation:
Given
angle given is [tex]23^{\circ}[/tex]
[tex]RC=16[/tex]
Using trigonometry
[tex]\Rightarrow \sin 23^{\circ}=\dfrac{RC}{PC}\\\\\Rightarrow \sin 23^{\circ}=\dfrac{16}{X}\\\\\Rightarrow X=\dfrac{16}{\sin 23^{\circ}}\\\\\Rightarrow X=40.948\approx 40.9[/tex]
Using cosine formula
[tex]\Rightarrow \cos 23^{\circ}=\dfrac{PR}{X}\\\\\Rightarrow PR=40.9\times \cos 23^{\circ}\\\Rightarrow PR=37.69\approx 37.7[/tex]

7 squared + 24 squared = 625
49 + 576 = 625
then after that do the square root of 625 and you get 25 so the awnser is 25
Step-by-step explanation:
So plug in your terms to get (hypotenuse)^2= 49 + 576
hypotenuse)^2= 625
Do square root of each side to get
Hypotenuse =25 in
That is the value for your missing side.

Step-by-step explanation: the distance from point a to point B is 10.8. 10.8 divided by 3 is 3.6, so you have to find a point that 3.6 from point a. Using a graph, I found the answer to be (3,7)
What is x? Plz help me this question is worth 13 points.
Answers
Answer:
5.25
Step-by-step explanation:
So lets gather our information(Note that I use x as the small x value and X as the larger and missing value)
First off, we know that x is 3.
We know that the X value is a scale of x by 1.75.
We can think of this as 1.75x.
So to find X, we can multiply x by the scale 1.75:
x*1.75=X
plug in the value we know for x:
3*1.75=X
=
5.25=X
So our answer is 5.25!
Hope this helps! :)

Which expression is equivalent to this quotient?
4x^2 -8x -5/ 4x^2 - 25
A. -1/5
B. 2x - 1/ 2x - 5
C. 2x + 1/ 2x + 5
D. 2x - 5/ 2x + 5
Answers
The answer is (C) 2x+1/ 2x+5.
This is just finding like terms.
Like terms are terms that are the same, like 2x and 3x for example, would be like terms. (This is not in the problem by the way.) Just divide the like terms, and that's your answer.
I tried to give a good explanation but I'm super tired. Just trying to help.
The expression is equivalent to the quotient is (2x+1)/(2x+5). Therefore, option C is the correct answer.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Given that, (4x²-8x-5)/(4x²-25)
= (4x²-10x+2x-5)/((2x)²-(5)²)
= [2x(2x-5)+1(2x-5)]/(2x-5)(2x+5)
= [(2x-5)(2x+1)]/(2x-5)(2x+5)
= (2x+1)/(2x+5)
Therefore, option C is the correct answer.
