A person who weighs 150 pounds weighs 25 pounds on the Moon. Suppose an object weighs 80 pounds on the Moon. What’s the objects weight on the Earth?

Answer:

c) [-16, 4]

Step-by-step explanation:

Given equation,

→ 2 + |t + 6| = 12

Now the value of t will be,

→ 2 + |t + 6| = 12

→ 2 + t + 6 = 12 || → 2 -(t + 6) = 12

→ t + 8 = 12 || → -t - 4 = 12

→ t = 12 - 8 || → -t = 12 + 4

→ [ t = 4 ] || → [ t = -16 ]

Hence, value of t is 4 (or) -16.

Answer:

A = ₤500

B = ₤420

C = ₤340

D = ₤260

See Image 1 attached for the plot.

Step-by-step explanation:

The bank account starts with ₤500, so that is the amount at 0 months on the chart.

After one month, ₤80 is withdrawn, and the total becomes:

[tex]500-80=420[/tex]

After two months, another ₤80 is withdrawn from the account:

[tex]420-80=340[/tex]

Finally, after 3 months, ₤80 is withdrawn again:

There doesn't seem to be enough information to answer problem 1.

I would ask your teacher for clarification.

=============================================

Problem 2

--------------------------

Explanation

x = number of cards, which is some positive whole number.

Your teacher has provided these facts:

which I'll call "fact 1", "fact 2", "fact 3" in that order.

For now I'll focus on fact 3.

Recall that multiples of 5 either end with 0 or 5. Example: 25 is a multiple of 5, and so is 60.

Fact 3 says that we get a remainder 2 when dividing by 5. Therefore, x must be something like 25+2 = 27 or 60+2 = 62. I added 2 to each previous example mentioned earlier.

In short, the value of x must end with 2 or 7.

-------------------

Now focus on fact 1.

The multiples of 4 are {4, 8, 12, ...} all of which are even since 2 is a factor of each.

Add remainder 3 to each item to get {7, 11, 15, ...} and it should be fairly obvious that all of these items are odd.

What does this mean? It means we know 100% that x ends with 7 in the units digit. If x has 2 in the units digit, then x would be even, but it's not in the set {7, 11, 15, ...}

So this is very useful info that x ends with 7.

x could be any of these: {7, 17, 27, 37, ...}

-------------------

We've looked at facts 1 and 3 so far. The only thing left is fact 2.

List the multiples of 3 to get

{3, 6, 9, 12, 15, 18, ...}

then add on the remainder 2 giving this new updated set

{5, 8, 11, 14, 17, 20, ...}

We see that 17 is in that set which fits the criteria of "the number ends with 7". So it's possible that 17 is the answer.

But 17/4 = 4 remainder 1 which doesn't fit fact 1 (since we want remainder 3 instead).

But we can add on multiples of 3*5 = 15 to extend to this new set of

{17, 32, 47, 62, 77, ...}

then erase stuff that ends with 2 to get

{17, 47, 77, ...}

Through guess and check, 47 will work out as shown in the next section below. Therefore, 47 is the final answer.

-------------------

Check:

We get the proper remainders mentioned earlier, so the answer has been confirmed.

-------------------

Side note: The convention for problems like this is to use the Chinese Remainder Theorem. However, I decided not to use it because I wasn't sure if your teacher has covered modulo arithmetic yet or not. If s/he has covered it, then I recommend using that method instead of what I posted above. It's a much more efficient option.

Answer: 0.555555556

Step-by-step explanation:

15/27=0.555555556

Checking work by plugging it in: 27x0.555555556=15

======================================================

Work Shown:

a = old value = 15

b = new value = 27

c = change in values

c = b-a

c = 27-15

c = 12

The positive c value tells us that we have an increase.

Then divide over the starting value a = 15

c/a = 12/15 = 0.80

Move the decimal point two spots to the right to go from 0.80 to 80%

Or multiply 0.80 with 100% to get 0.80*100% = 80%

We have a percent increase of 80%

-------------------

Check:

80% of 15 = 0.80*15 = 12

If the stock increases by 80%, then it has increased by $12 to go from $15 a share to 15+12 = 27 dollars a share. This confirms the answer.

A slight shortcut would be to say 1.80*15 = 27

The multiplier 1.80 represents an increase of 80% since 100% + 80% = 1 + 0.80 = 1.80

The classification of each game as fair or not, using probabilities, is given as follows:

1. Fair.

2. Fair.

A fair game is a game in which each competitor will have the same chance of winning the game.

These changes are calculated using probabilities, which is the number of desired outcomes in the context of the experiment divided by the number of total outcomes.

The probability of two tails when two fair coins are tossed is:

p = 1/2 x 1/2 = 1/4.

The probability of one head and one tail when two fair coins are tossed is:

p = 1/2 x 1/2 = 1/4.

In game 1, the two players have the same probability of winning, hence it is a fair game.

When two dice are thrown, there are 36 possible outcomes. The number of outcomes regarding the sums are given as follows:

Answer:

Neither, Perpendicular, Parallel, Neither

Step-by-step explanation:

Parallel lines have the same slope.

Perpendicular lines have slopes that are negative reciprocals.

Answer:

y=-x+16

Step-by-step explanation:

let’s put this equation in slope intercept form: y=mx+b

2x+2y=-8

-2x.      -2x

2y=-2x-8

/2.  /2.  /2

y=-x-4

We know parallel lines have the same slope as each other so let’s fill in the equation with the given point

10=-(6)-4

10=-10

We need to add 20 more to the y intercept to make this true like this

y=-x-4+20

y=-x+16

Now let’s see if it works

10=-(6)+16

10=10

It works so this is the equation

Hopes this helps please mark brainliest

Answer: y = -x +16

Step-by-step explanation:

rearrange the equation to make y the subject

2y = -2x -8

y = -x-4

equation of line parallel to the line (gradient will be the same)

y = -x +c

Substitute the x and y values into the parallel line equation

10 = -6 + c

10 + 6 = c

16 = c

Therefore, the equation of the line parallel to 2x + 2y = -8 is y = -x +16

An integer between 1000 and 9999 inclusive is called balanced if the sum of its two leftmost digits equals the sum of its two right most digit. Therefore, there are 615 balanced integers .

If the common sum of the first two and last two digits is n ,

such that 1 ≤n ≤ 9 , there are n choices for the first two digits and n +1 choices for the second two digits (since zero may not be the first digit).

This gives:

            ∑⁹ₙ₋₁ n(n+1) balanced numbers.

If the common sum of the first two and last two digits is n, such that:

                   10≤ n ≤ 18

there are 19 - n choices for both pairs.

This gives : ∑ₙ ₁₀¹⁸ ( 19 - n)²

               = ∑₁⁹ n²

               = 285balanced numbers.

Thus, there are in total 330 + 285 = 615 balanced numbers.

Both summations may be calculated using the formula for the sum of consecutive squares, namely:

Marcelo will have to take 50 shots in order to miss 30 shots because the ratio of shots to missed shots is 5:3

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls.

To solve this question, we can simply compare the ratio or proportion of shots to the number of missed shots.

In every 25 shots taken, he made 10 shots. This implies he lose 15 shots.

So, for every 25 shots, he lost 15 shots.

How many shots did he take to miss 30 shots.

25 shots = 15 missed shots

x shots = 30 missed shots

crossed multiply both sides and solve for x

x = (30 * 25) / 15

x = 50 shots.

The slope of a line that is parallel to the line y = x + 2 is 1.

What is slope?

A line's steepness is determined by its slope. In mathematics, the slope is determined by "rise over run" (change in y divided by change in x).

Given the equation of line: y = x + 2

We have to find the slope of a line that is parallel to the given line.

Since any line parallel to the given line  y = x + 2  will have the same slope as that of a given line

The general equation of line is given as y = mx + c

where. m is the slope of the line and c is y-intercept.

Thus for given equation of line y = x + 2
