Answer:

Opposites in the numbers world refer to numbers that have the same absolute value, but one is negative, while the other is positive.

For a real world example, consider if you have your friend 5 dollars. The amount you have in the transaction is the opposite of the amount he has in the transaction.

The opposite of a number X is that number that when added to X produces zero. The opposite of X is denoted with −X.

The opposite of a number has the same absolute value as the number but an opposite sign. For example, the opposite of 1 is equal to −1 because 1 + (−1) = 0.

The opposite of zero is zero. This is the only number whose opposite is equal to itself. So zero is the neutral element with regard to addition.

In turn, the opposite of a complex number corresponds to a rotation of 180°.

=5sqrt(2)

Step-by-step explanation:

The length of a line segment is given by

d = sqrt( (x2-x1)^2 + (y2-y1)^2 )

   = sqrt( (9-2)^2 + (8-5) ^2)

   = sqrt(7^2 + 3^2)

  = sqrt(49+9)

 = sqrt(50)

=sqrt(2*25)

We know that sqrt(ab) = sqrt(a)sqrt(b)

sqrt(25)sqrt(2)

=5sqrt(2)

The answer is 5sqrt of 2

if the die has six sides, the probability that he will roll 2 again is 1/6 since there’s only one 2 out of the six sides

The probability jack will get 2 on the next roll is 1/6.

It is the ratio that determines how likely a certain event can occur within a set of possible events.

The given dice has 6 sides.

The number 2 occurs only on one side of a die.

Therefore, if he were to roll the dice one more time, the probability that he would get 2 can be given by 1/6.

Therefore, the probability that jack will get 2 on the next roll is 1/6.

Step-by-step explanation:

given the 2 equations

x + 2y = 27 → (1)

2x + 3y = 46 → (2)

Rearrange (1) expressing x in terms of y by subtracting 2y from both sides

x = 27 - 2y ← substitute into (2)

2(27 - 2y) + 3y = 46

54 - 4y + 3y = 46

54 - y = 46 ( subtract 54 from both sides )

- y = - 8 ( multiply both sides by - 1 )

y = 8 → D

Step-by-step explanation:

The absolute value always returns a positive result, however the expression inside can be positive or negative, that is

4x - 1 = 7 OR 4x - 1 = - 7

4x - 1 = 7 ( add 1 to both sides )

4x = 8 ( divide both sides by 4 )

x = 2

OR

4x - 1 = - 7 ( add 1 to both sides )

4x = - 6 ( divide both sides by 4 )

Step-by-step explanation:

The college graduate will have received a total income of $699,848.22 after ten years, starting with a salary of $60,000 and increasing by 4% each year.

To find the total income the college graduate will have received after ten years, we need to calculate the salary for each year and sum them up. The first year salary is $60,000. After that, the salary increases by 4% each year. To calculate the salary for each subsequent year, multiply the previous year's salary by 1.04. Here are the calculations for each year:

Now, sum up the salaries for each year:

Total income after ten years = $60,000 + $62,400 + $64,896 + $67,491.84 + $70,190.95 + $72,999.66 + $75,923.45 + $78,967.79 + $82,138.35 + $85,440.18 = $699,848.22

Therefore, the college graduate will have received a total income of $699,848.22 after ten years.

The college graduate will receive a total income of approximately $720,360 over ten years.

1. To calculate the total income a college graduate will receive over ten years with an initial salary of $60,000 and a 4% annual raise, we can use the formula for the sum of a geometric series.

2. The formula for the sum of the first n terms of a geometric series is given by:

Sum = a(1 - [tex]r^{n}[/tex]) / (1 - r)

3. Substituting the given values:

a = 60,000, r = 1.04, n = 10

Sum = 60,000 * (1 - [tex]1.04^{10}[/tex]) / (1 - 1.04)

Sum = 60,000 * (1 - 1.48024) / ( -0.04)

Sum = 60,000 * (-0.48024) / (-0.04)

Sum = 60,000 * 12.006

Sum ≈ 720,360

4. Total Income:

Thus, the total income received after ten years is approximately $720,360.

Answer:

$81

Step-by-step explanation:

The total cost would be cost + cost(tax), or cost(1 + tax).

So here, it would be 75(1 + 0.08).

That is equal to $81.

Answer: [tex]8mm,\ 41cm,\ 790dm,\ 788m,\ 537km[/tex]

Step-by-step explanation:

To solve this problem you must:

1. Write the lenghts given in the problem in the same units.

2. Let's convert all the units to meters. Then:

537 km to m:

[tex](537km)(\frac{1,000}{1km})= 537,000m[/tex]

790 dm to m:

[tex](790dm)(\frac{1m}{10dm})=79m[/tex]

41 cm to m:

[tex](41cm)(\frac{1m}{100cm})=0.41m[/tex]

8 mm to m:

[tex](8mm)(\frac{1m}{1,000mm})=8*10^{-3}m[/tex]

Now you rewrite them in increasing order:

[tex]8mm,\ 41cm,\ 790dm,\ 788m,\ 537km[/tex]

Answer:

The correct order is,

8mm, 41 cm, 790 dm, 788m, 537 km

Step-by-step explanation:

It is given some measures of lengths

537 km, 790 dm, 41 cm, 8 mm, 788 m

Convert this into single unit

we can convert this into Meter

1). 537 km = 537000 m

2). 790 dm = 79 m

3). 41 cm = 0.41 m

4). 8 mm = 0.008 m

5). 788 m = 788 m

From this we get the correct order,

8mm, 41 cm, 790 dm, 788m, 537 km

50 quarts is greater than 12 gallons.

Given that, 12 gallons and 50 quarts.

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

We know that, 1 quarts = 0.25 gallons

Here, 50 quarts = 50×0.25

= 12.5 gallons

So, 12.5 gallons > 12 gallons

Therefore, 50 quarts is greater than 12 gallons.

Answer:

x = 7

Step-by-step explanation:

Similar

The two triangles

1) the one making up the peak of the large triangle

2)the large triangle  

are similar. That is because the 2 bases are parallel and corresponding angles are equal. The third angle at the peak is common. So by AAA they are similar.

Proportion

Therefore the sides are in proportion.

5/40 = 3/(2x + 10)

Solution

Cross multiply

5*(2x + 10) = 40*3

Remove the brackets on the left. Combine the right.

10x + 50 = 120          

Subtract 50 from both sides

10x + 50 - 50 = 120 - 50

10x = 70

Divide by 10

10x/10 = 70/10

x = 7

Answer:

We have 17 inches = (37/100) · x;

x = 17 ÷ (37/100);

x = 17 · (100/37);

x = 1700 / 37;

x ≈ 46;

Step-by-step explanation:

Final answer:

To find out how much rain a city usually gets, divide the rain it received last year (17 inches) by the percentage of normal rainfall it represented (37%). The city normally receives about 45.95 inches of rain annually.

Explanation:

The student is asking how to calculate the usual annual rainfall for a city if the city received 17 inches of rain last year which was only 37% of their normal rainfall. To find the answer, we want to determine what 100% of their normal rainfall would be. We can use the formula:

Normal Rainfall = (Last Year's Rainfall / Percentage of Normal Rainfall) x 100

Substituting the given values into our formula, we get:

Normal Rainfall = (17 inches / 37%) x 100

Normal Rainfall = (17 / 0.37) inches

Normal Rainfall = 45.95 inches

Therefore, the city usually receives about 45.95 inches of rain annually.

Answer:

rise/run

Example:

say the lines is going 3 up and 4 to either side, the slope would be 3/4 :)

Answer:

Step-by-step explanation:

Step One: Identify two points on the line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

Step Three: Use the slope equation to calculate slope.

Let's say that points (15, 8) and (10, 7) are on a straight line. What is the slope of this line?

Step One: Identify two points on the line.

In this example we are given two points, (15, 8) and (10, 7), on a straight line.

Step Two: Select one to be (x1, y1) and the other to be (x2, y2).

It doesn't matter which we choose, so let's take (15, 8) to be (x2, y2). Let's take the point (10, 7) to be the point (x1, y1).

Step Three: Use the equation to calculate slope.

Once we've completed step 2, we are ready to calculate the slope using the equation for a slope.

We said that it really doesn't matter which point we choose as (x1, y1) and the which to be (x2, y2). Let's show that this is true. Take the same two points (15, 8) and (10, 7), but this time we will calculate the slope using (15, 8) as (x1, y1) and (10, 7) as the point (x2, y2). Then substitute these into the equation for slope.

Answer:

It's A.

Step-by-step explanation:

For every value of x there is one value of y  - we can draw a vertical line through any value of x and it will pass through only one value of y.

Therefore it is a one-to-one function.

Answer:

Option A

Step-by-step explanation:

The curve given is an increasing curve cutting x axis once and y axis once.

Any vertical line cuts only once the curve. Hence this is a function only.

We find that for every y in the range there is only one x corresponding to that.

Hence this curve is not a many to one curve.  It is not linear because it is not  a straight line.  It is a function.

Hence only correct option is

a) The curve is a one to one function.

Answer:

3,384 miles

Step-by-step explanation:

If can cover 94 miles in 1/6 of an hour.  (1/6 hour)*6 = 1 hour, so multiply 94 by 6 to see how far the plane will travel in 1 hour.  

94(6) = 564 miles in one hour

Multiply that by 6 to see how far the plane travels in 6 hours

564(6) = 3,384  miles

The airplane can cover 3,384 miles in 6 hours.

The formula for finding the distance covered is:

Distance = speed*time

It is given that it can cover 94 miles in 1/6 hours.

This should be converted to per hour.

For this, multiply the distance by 6.

94 miles * 6 = 564 miles

The speed of the plane is 564 miles per hour.

The distance that the plane covers in 6 hours = 564 miles per hour * 6 hours

= 3,384 miles.

Therefore, we have found that the plane can cover 3,384 miles in 6 hours.

In a square all sides have the same length.

And the area of a square is given by the formula:

[tex]Area=(length)^2[/tex]

so, substituting that the length is [tex]2x+5[/tex]

[tex]Area=(2x+5)^2[/tex]

and we solve this squared binomial with the formula:

[tex](a+b)^2=a^2+2ab+b^2[/tex]

in this case [tex]a=2x[/tex] and [tex]b=5[/tex]

thus, we get:
