(pls) Find the slope of the line through (9, 4) and (0, 5).

Answer:

4,923.75ft²

Step-by-step explanation:

The area of the backyard = Length * width \

Area of the backyard = 75 3/4 * 81 1/4

Area of the backyard = 303/4 * 325/4

Area of the backyard = 6,154.6875ft²

If 3/4 of the fence is finished, the area of the finished part is expressed as;

Finished part = 1/5 * 6,154.6875

Finished part = 1,230.9375ft²

Part left unfinished = 6,154.6875-1,230.9375

Part left unfinished  = 4,923.75ft²

Answer: 3,750 miles

Step-by-step explanation:

Route takes him 125 miles each way so in a day he travels:

= 125 + 125

= 250 miles

He made 15 roundtrips so total miles is:

= 15 * 250

= 3,750 miles

Answer:

QR=PS in a parallelogram

Therefore, 17.7 is the right answer.

Solve for x over the real numbers:

x^2 - 10 x - 27 = 0

Hint: | Solve the quadratic equation by completing the square.

Add 27 to both sides:

x^2 - 10 x = 27

Hint: | Take one half of the coefficient of x and square it, then add it to both sides.

Add 25 to both sides:

x^2 - 10 x + 25 = 52

Hint: | Factor the left hand side.

Write the left hand side as a square:

(x - 5)^2 = 52

Hint: | Eliminate the exponent on the left hand side.

Take the square root of both sides:

x - 5 = 2 sqrt(13) or x - 5 = -2 sqrt(13)

Hint: | Look at the first equation: Solve for x.

Add 5 to both sides:

x = 5 + 2 sqrt(13) or x - 5 = -2 sqrt(13)

Hint: | Look at the second equation: Solve for x.

Add 5 to both sides:

Answer:

x = 5 + 2√(13) or x = 5 - 2√(13)

Answer:

y = 3x + b

Step-by-step explanation:

The slope of y=mx+3 that passes through (-3,4) is found like this:

1. Substitute the y and x values in (4 = m*(-3) + 3).

2. Simplify by subtracting 3 from each side (1 = m*(-3)).

3. Simplify by dividing each side by -3 (-1/3 = m).

Since the slope of perpendicular lines are negative reciprocals, the slope of the perpendicular line is 3.  The y-intercept can be anything and it will still be perpendicular.

Answer: ↓↓↓

Step-by-step explanation:

Part A

131.5 or $131,500 is the starting value of the plane X before it started to depreciate.

Part B (They meant plane Y as in plane Y but plane B as in the second plane, look at the table and Part C)

b (m) = 177,233 (0.024)^m

$177,233 is the starting value of plane Y.

The value depreciates by 2.4% and that is the same as 0.024, except 0.024 is in decimal form.

Part C

b (t) = 177,233 (0.024 x 12)^t

b (t) = 177,233 (0.288)^t

I multiplied 12 by the depreciation because for the whole equation to actually show the depreciation in years I had to solve how much the plane would depreciate in 1 year. So, since 12 months is 1 year, I multiplied 12 by 0.024.

That's it! I hope I'm right because this took a lot of thinking lol

Answer:

CD = 25 ft

Step-by-step explanation:

[tex] \triangle CDE \sim \triangle RST[/tex]

[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]

(Corresponding sides of similar triangles are in proportion)

[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]

[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]

[tex]\therefore CD = 5\times 5[/tex]

[tex]\therefore CD = 25\: ft[/tex]

Answer:

CD = 25 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values

[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex]  ( cross- multiply )

32CD = 800 ( divide both sides by 32 )

CD = 25

Answer:

Two mathematical terms are alike (not alike) , if they have same (different) variables & in same (different) mathematical treatment.

Step-by-step explanation:

Two mathematical terms are alike, if they have same variables & in same mathematical treatment.

Eg : 2 xy , 5 xy. These are alike, as they have product of x & y being multiplied with constants.

They can be added, subtracted by adding or subtracting their constants.

2 xy + 5 xy =  (2 + 5) xy = 7 xy

5 xy - 2 xy =  ( 5- 2 ) xy = 3 xy

Percent = 96%

Step-by-step explanation:

We arrange the numbers in increasing order:

0.9, 1.4, 2, 2.4, 3.5

Since there are five terms, the median is the third term, which is 2.

The median of the given data set is 2.

The median is the middle number in a sorted, ascending or descending list of numbers.

Given is a data set, 1.4, 0.9, 2.4, 3.5, 2​, we need to find median,

Rearranging the data from lowest to greatest,

0.9, 1.4, 2, 2.4, 3.5

Since, the median is the middle most value in a data, therefore, the middle most value of the given data is 2.

Therefore, we can say the median is 2.

Hence, the median of the data is 2.

Answer:

  a) 3003

  b) 1419

Step-by-step explanation:

a) With no restrictions, the problem amounts to counting the number of combinations of 14 people taken 6 at a time. That is ...

  14!/(6!(14-6)!) = 3003 . . . teams with no restrictions

__

b) With the restrictions, there are two cases:

  (i) all 6 people are taken from the 12 that exclude the couple. That number of combinations is ...

  12!/(6!(12-6)!) = 924

  (ii) 4 people are taken from the 12 that exclude the couple, and the couple fills the last two team slots. That number is ...

  12!/(4!(12-4)!) = 495

The sum of the counts of these two cases is ...

  924 +495 = 1419 . . . teams with inseparable couple
