The average distance from the sun to Jupiter is 778 million km. The distance is 550 million km greater than the average distance from the sun to mars. Write and solve an equation to find the average distance that mars is from the sun (in millions of km)
The average distance from the sun to Mars can be found by setting up an equation based on the given information. Subtracting 550 from the average distance to Jupiter gives the average distance to Mars, which is 228 million km.
Explanation:We know that the average distance from the sun to Jupiter is 778 million km, which is 550 million km more than the distance from the sun to Mars. We could express it in the form of an equation and solve to find the average distance that Mars is from the sun. Let's denote that Mars is 'x' million km from the sun. Then we can write it as:
x + 550 = 778
To find x, we need to subtract 550 from both sides of the equation, which gives us:
x = 778 - 550
And so, the distance from the sun to Mars is x = 228 million km.

A certain gas station requires a minimum of $5 to use a debit card. You plan on buying a soda and however many bags of cheetos required to use your debit card. A soda costs $1.20 and bags of cheetos cost $1.40 each. Let x be the number of bags of cheetos you buy, and create an inequality that models the situation above
Answer:
1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5
Step-by-step explanation:
So since you are only buying 1 soda and you are buying multiple bags of Cheetos so you are able to use you debit card and meet the requirement of at least $5, you can make the inequality:
1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5
where x is the number of bags of Cheetos.

15.755264 round to the nearest tenths
Answer:
15.8
Step-by-step explanation:
Rounding to the nearest tenths means we are focusing on the number 7 and the number after it- 5. Because it is a 5, we will round the number 7, one higher. If it were to be a 4, it would stay a 7.
Answer:
15.8 is the Answer
Step-by-step explanation:
1) 5 in the hundreds place will be turn to 6 due to the fact that in can round up because a 5 is in the thousandth place.
2) Since 6 is 5 and greater than 5 it will round up 7 in the tenths place to 8.

The answer is 2. The rate of change between -1 and 0 is 3 and between 0 and -1 is 1. The average between 3 and 1 is 2.
Answer:
- 2
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ - 1, 1 ]
f(b) = f(1) = 1 - 2 = - 1
f(a) = f(- 1) = 1 + 2 = 3
Hence
average rate of change = [tex]\frac{-1-3}{1-(-1)}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

Judy needs to take out a personal loan for $2,500 for tuition assistance. Her bank has offered her one of the four loan packages outlined in the chart below. Determine which of the four loans will be cheapest for Judy in the long run. All interest rates are compounded monthly.
The answer would be Loan A
even though she'll pay more per month, with the others she'll pay be paying more by the time she as payed it off due to having to pay interest over a longer period of time
Answer:
Loan A is the cheapest.Step-by-step explanation:
The different loan plans are showed in the image attached.
Loan A: 12 months of duration with 9.50%.
Loan B: 24 months of duration with 8.75%.
Loan C: 36 months of duration with 7.75%.
Loan D: 48 months of duration with 6.60%.
Now, all loans are compouneded monthly. Let's the compound interest formula
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Loan A:
[tex]A=2500(1+\frac{0.095}{12} )^{12(1)}\\A=2,748.12[/tex]
Loan B:
[tex]A=2500(1+\frac{0.095}{24} )^{24(2)} \\A=2500(1.004)^{48}\\ A=3,028.02[/tex]
Loan C:
[tex]A=2500(1+\frac{0.095}{36} )^{36(3)} \\A=2500(1.003)^{108}\\ A=3,454.94[/tex]
Loan D:
[tex]A=2500(1+\frac{0.095}{48} )^{48(4)}\\ A=2500(1.002)^{192}\\ A=3,668.95[/tex]
Now, if you compare, you will observe that Loan A offer the cheapest result for Judy.
Therefore, Judy should use the Loan A plan.

Aileen purchased a box of ten juice boxes for her party. Each juice box contains eight of juice. At the end of the party,two juice boxes were left. How many ounces of juice were consumed and how many were left???
Answer:
64 oz. were consumed and 16 oz. were left.
Step-by-step explanation:
8*10 = 80 oz. of juice total.
10-2=8 boxes consumed
8*8(number of oz. per box)=64 oz. consumed
2*8=16 oz. left
64+16=80 checks out.
The parallelogram shown below has an area of 135 units2 Find the missing base.
===================================================
Explanation:
The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.
The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135
Therefore, 15*b = 135
Divide both sides by 15 and we isolate b
15b = 135
15b/15 = 135/15
b = 9
So the base is 9
Check:
area = base*height = 9*15 = 135
so the answer is confirmed
side note: we never use the value 17 at all. It is likely put in there as a distraction.

9

the scuba diver standing on a boat is at an altitude of 1.3 meters above sea level. The scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute. what equation can be used to represent the divers altitude
Since the scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute, the equation that can be used to represent the divers altitude is [tex]y = -5x + 1.3[/tex]
What is the eqquation?The standard equation is [tex]y = mx + b[/tex]
y,x = variables
m = rate of change
b = initial value of y.
y = the height of the scuba driver after x minutes.
Given that b = 1.3
m = -5.6(decrease in altitude)
Then the equation can be written as ; [tex]y = -5x + 1.3[/tex]
hence scuba driver height is given by the equation [tex]y = -5x + 1.3[/tex]

The equation that represents the scuba diver's altitude after jumping into the water is y = 1.3 - 5.6t, where y is in meters and t is in minutes.
Let y represent the diver's altitude in meters relative to sea level after t minutes. Initially, at sea level, we have y(0) = 1.3. Due to the descent in water, the altitude decreases by 5.6 meters per minute, which means the altitude change per minute can be represented by
-5.6t. Thus, the equation that can be used to represent the diver's altitude as a function of time is:
y = 1.3 - 5.6t
where y is in meters and t is in minutes.

B(-∞,21)
C(21,+∞)
D(-∞,21)U(21,+∞)
ANSWER
A
[tex]( - \infty , + \infty )
[/tex]
EXPLANATION.
The given function is
[tex]f(x) = 2 {x}^{3} + 21[/tex]
Let
[tex]y= 2 {x}^{3} + 21[/tex]
Solve for x.
[tex]2 {x}^{3} = y - 21[/tex]
[tex] {x}^{3} = \frac{1}{2} y - \frac{21}{2} [/tex]
Take cubic root of both sides,
[tex]x = \sqrt[3]{ \frac{1}{2} y - \frac{21}{2} } [/tex]
x is defined for all real values of y.
The range refers to the values of y, for which x is defined.
Hence the range is all real numbers.
In interval notation, we write this as,

What is the value of this expression?
22.26 x 10^7 is the correct answer
Multiply the decimal numbers:
5.3 x 4.2 = 22.26
When multiplying scientific numbers, add the exponents together: 4+3 = 7
So you now have 22.26 x 10^7
Now you need to convert 22.26 to a scientific number, by only having one number to the left of the decimal point.
You need to move the decimal 1 place to the left, which means you need to add 1 more to the exponent.
The final answer would be 2.226 x 10^8

What is a theoretical and Experimental Probability?
Answer:
See below...
Step-by-step explanation:
Theoretical probability is the probability that something should happen based on the beginning conditions. Such as having a jar of 30 marbles with 5 being blue. The probability of pulling out a blue marble when selecting 1 marble is
5/30, or 1/6. Theoretically you should pull one blue marble out every 6 times you pull a marble out.
This isn't guaranteed to happen though, that's where experimental probability comes form.
Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes. This is based on what actually happened. Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles. Your experimental probability is
2/10, or 1/5, which doesn't match the theoretical probability. The more times this experiment is conducted, the closer your result will be to the theoretical probability
