Answer:

x = 10

Step-by-step explanation:

x = k/y

15 = k/-4

k = -60

x = -60/-6

x = 10

Answer:To calculate the standard deviation of those numbers:

1.Work out the Mean (the simple average of the numbers)

2.Then for each number: subtract the Mean and square the result.

3.Then work out the mean of those squared differences.

4.Take the square root of that and we are done!

Step-by-step explanation:

To find 1/3 of 180, we need to multiply 180 by 1/3, or divide 180 by 3. For this one, we will try both methods.

180/1 x 1/3 = 180/3 or 60

180 / 3 =60

Since we now know how much was sold, we need to find what is left. We need to subtract 180 by 60.

180-60=120

So 120 bottles are left. Now, since 3/5 of 120 were sold the next day, we need to multiply 120 by 3/5.

120/1 x 3/5 = 360/5 or 72.

Now we know that 72 bottles were sold on Saturday. Subtract 120 by 72 to know how much is left in total.

120-72=48

60 bottles of water were sold on Friday.

72 bottles of water were sold on Saturday.

There were 12 more bottles sold on Saturday than Friday.

Answer:

5.6715 * 10^26 kg

Step-by-step explanation:

Given that :

Mass of earth = 1/95 the mass of saturn

If Mass of earth = 5.97 x 10^24 kg

Let the mass of saturn = x

5.97 x 10^24 kg = 1/95 * x

5.97 x 10^24 kg = x / 95

x = 95 * 5.97 x 10^24 kg

x = 567.15 * 10^24

x = 5.6715 * 10^26 kg

Mass of saturn = 5.6715 * 10^26 kg

Answer:

Dimension => 10 m × 9.6 m

Step-by-step explanation:

From the question given above, the following data were obtained:

Area (A) = 96 m²

Circumference (C) = 39.2 m

Dimension =.?

Next, we shall determine the Lenght and breadth of the rectangle. This can be obtained as follow:

Let L be the Lenght

Let B be the breadth

Area of a rectangle = L × B

96 = L × B ..... (1)

Circumference of rectangle = 2(L + B)

39.2 = 2(L + B) .... (2)

From equation 2, make L the subject

39.2 = 2(L + B)

Divide both side by 2

39.2 /2 = L + B

19.6 = L + B

Rearrange

L = 19.6 – B ....(3)

Substitute the value of L in equation 3 into equation 1

96 = L × B

L = 19.6 – B

96 = (19.6 – B ) × B

Clear bracket

96 = 19.6B – B²

Rearrange

B² – 19.6B + 96 = 0

Solving by factorisation

B² – 10B – 9.6B + 96 = 0

B(B – 10) – 9.6(B – 10) = 0

(B – 9.6)(B – 10) = 0

B – 9.6 = 0 or B – 10 = 0

B = 9.6 or B = 10

Substitute the value of B into equation 3:

L = 19.6 – B

B = 9.6

L = 19.6 – 9.6

L = 10

Or

L = 19.6 – B

B = 10

L = 19.6 – 10

L = 9.6

Since the length is always longer than the breadth,

Length (L) = 10 m

Breadth (B) = 9.6 m

Finally, we shall determine the dimension of the rectangle. This can be obtained as follow:

Length (L) = 10 m

Breadth (B) = 9.6 m

Dimension =?

Dimension = L × B

Dimension = 10 m × 9.6 m

Answer:

4.718592

Step-by-step explanation:

To get to -14.4 from 18 you multiply 18 x 0.8

Repeat that until you get to the 7th term

18 (1st)

18 x 0.8 = -14.4 (2nd)

-14.4 x 0.8 = 11.52 (3rd)

11.52 x 0.8 = 9.216 (4th)

9.216 x 0.8 = 7.3728 (5th)

7.3728 x 0.8 = 5.89824 (6th)

5.89824 x 0.8 = 4.718592 (7th)

Answer:

2/9 - 1/6 = 1/18

Step-by-step explanation:

2/9= 4/18 and 1/6=3/18

so...

4/18-3/18=1/18

Hope This Helps!

Answer:

1/18

Step-by-step explanation:

find the LCD

= 18

say

18

= 18 ÷ 9

= 2

= 18 ÷6

= 3

now say

2 × 2 = 4

3 × 1 = 3

4-3/18

= 1/18

Explanation:

The length CD can be found from the Pythagorean theorem.

  CF² + CD² = DF²

  2² + CD² = (2√10)²

  CD² = 40 -4 = 36

  CD = √36 = 6

From here, any of several methods could be used to find the area of ΔDEF.

One of them is to subtract the areas of the triangles that are not ΔDEF from the area of the rectangle ABCD.

  area ABCD = bh = (6 cm)(5 cm) = 30 cm²

  area ΔADE = 1/2bh = 1/2(4 cm)(5 cm) = 10 cm²

  area ΔBEF = 1/2bh = 1/2(2 cm)(3 cm) = 3 cm²

  area ΔCDF = 1/2bh = 1/2(6 cm)(2 cm) = 6 cm²

Then the area of interest is ...

  area ΔDEF = area ABCD -area ΔADE -area ΔBEF -area ΔCDF

  area ΔDEF = (30 -10 -3 -6) cm²

  area ΔDEF = 11 cm²

__

Alternate solution

If we define A as the origin of a coordinate system, then the coordinates of the vertices of ΔDEF are ...

  D(0, 5), E(4, 0), F(6, 3)

The area can be computed as half the absolute value of the sum of the determinants of 2×2 matrices consisting of adjacent points.

  [tex]A=\dfrac{1}{2}\left|\left|\begin{array}{cc}0&5\\4&0\end{array}\right|+\left|\begin{array}{cc}4&0\\6&3\end{array}\right|+\left|\begin{array}{cc}6&3\\0&5\end{array}\right| \right|\\\\=\dfrac{1}{2}|(0-20)+(12-0)+(30-0)|=\dfrac{1}{2}(22) = \boxed{11}[/tex]

Additional comment

The solution using coordinates is effectively equivalent to the computation of the area of trapezoid ABFD, less the areas of triangles EBF and AED.

Answer:

-1

Step-by-step explanation:

if -1 is to replace the x in the equation of f -1 then you fill it in and the equation would be 1 - (-1 * -1) + (-1 * -1 * -1) and if you put the equation together you'll just get -1

Carl ran for 85 minutes

Step-by-step explanation:

Since we know that he ran for 1 hour and 25 minutes and we know that 1 hour equals 60 minutes we can say that he ran for 60 + 25 minutes. Therefore he ran for 85 minutes.

8) y intercept is (0, 15) or 15

   slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)

9) y=10x+15

10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75

Answer:

77.23°

Step-by-step explanation:

Given that,

A 135.8 foot wire is attached to the top of the tower.

The wire is attached to the ground 30 feet from the bottom of the tower.

It means,

If we consider a triangle such that hypotenuse is 135.8 foot and base is 30 feet, it means we can use the trigonometry as follows :

[tex]\cos\theta=\dfrac{B}{H}\\\\\cos\theta=\dfrac{30}{135.8}\\\\\theta=77.23^{\circ}[/tex]

So, the angle the wire make with the ground is equal to 77.23°.

Answer:

11.2 feets

Step-by-step explanation:

Angle, P = 180 - (38 + 90) = 52

Using trigonometry :

Length pq:

SinP = opposite / hypotenus

Sin52 = 8.8 / pq

0.7880107 * pq = 8.8

pq = 8.8 / 0.7880107

pq = 11.167361

Hence, length of pq = 11.2 feets
