Answer:

192 gallons

Step-by-step explanation:

1.6 gallons x by 4 (the amount of times flushed in a day) = 6.4 gallons a day

6.4x30 (days in a month) = 192

192 gallons of water is being flushed a month

Answer:

192 gallons

Answer:

x=3

Step-by-step explanation:

Answer:

Well, for triangle rectangles, we have the relations:

Cos(A) = (adjacent cathetus)/(hypotenuse)

Sin(A) = (opposite cathetus)/(hypotenuse)

Tan(A) = (opposite cathetus)/(adjacent cathetus)

Where the adjacent cathetus is the cathetus that is adjacent to the angle, the opposite cathetus is the one that is opposite to the angle, and the hypotenuse is the side that is opposite to the 90° angle.

Here we want to solve 3 to 9.

3) We want to find values sin(D) and sin(E) in that triangle.

Remember the above relationship for the sin function, here will have:

sin(D) = 12/15 = 0.8

sin(E) = 9/15 = 0.6

4)

Sin(E) = 12/37 = 0.3243

Sin(D) = 35/37 = 0.9459

5)

Sin(E) = 45/53 = 0.8491

Sin(D) = 28/53 = 0.5283

6)

Remember that: Sin(A) = (opposite cathetus)/(hypotenuse)

In the image, 5 is the adjacent cathetus to the angle A, and the opposite cathetus to angle A is the one in front of it, 12, then the equation should be:

Sin(A) = 12/13

Now we should use the cosine relationship:

Cos(A) = (adjacent cathetus)/(hypotenuse)

7)

Cos(X) = 27/45 = 0.6

Cos(Y) = 36/45 = 0.8

8)

Cos(X) = 15/17 = 0.824

Cos(Y) = 8/17 = 0.4706

9)

Cos(X) = 13/26 = 0.5

Cos(Y) =  (13*√3)/26 = 0.866

Answer:

7^-11

Step-by-step explanation:

Given the expression 7^-5 = blank × 7^6

Let the blank be x

7^-5 = x × 7^6

x = 7^-5/7^6

According to law of indices a^b/a^c = a^b-c

x = 7^(-5-6)

x = 7^-11

Hence the missing factor is 7^-11

Answer:

149.5km/s

Step-by-step explanation:

speed= distance/time

distance= 299km

time=2hours

speed=299/2

speed=149.5km/h

Answer: 149.5 km/h or 92.58 mph

Step-by-step explanation:

Divide 299/2 to get the Kilometers Per Hour= 149.5

In Miles Per Hour it's about 92.584308 Miles per Hour.

Step-by-step explanation:

x2=36

We move all terms to the left:

x2-(36)=0

We add all the numbers together, and all the variables

x^2-36=0

a = 1; b = 0; c = -36;

Δ = b2-4ac

Δ = 02-4·1·(-36)

Δ = 144

The delta value is higher than zero, so the equation has two solutions

We use following formulas to calculate our solutions:

x1=−b−Δ√2ax2=−b+Δ√2a

Δ‾‾√=144‾‾‾‾√=12

x1=−b−Δ√2a=−(0)−122∗1=−122=−6

x2=−b+Δ√2a=−(0)+122∗1=122=6

9514 1404 393

Answer:

  x = -6 or +6

Step-by-step explanation:

You know from your multiplication tables that 6×6 = 36, so one answer is ...

  x = 6

You also know that the product of two negative numbers is positive, so another answer is ...

  x = -6

__

Check

  x² = 6² = 6×6 = 36

  x² = (-6)² = (-6)×(-6) = 36

_____

Alternate approach

If you like, you can rewrite the equation as ...

  x² -36 = 0

This can be factored to ...

  (x -6)(x +6) = 0

The zero product rule tells you this product will only be zero if one or the other factors is zero.

  x -6 = 0   ⇒   x = 6

  x +6 = 0   ⇒   x = -6

The two solutions are x = ±6.

Answer: The Doctor's.

Step-by-step explanation:

Claire's estimate was simply that, an estimate. The doctor's measurement on the other hand is the actual height of her brother because he actually got measured.

This means that the doctor's measurement is more accurate and would make more sense to be used.

Rise/run

4n - 8 > n + 17

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

The least value of the number of sheep is 9.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal =

Greater than and equal=

We have,

Rashid:

Number of sheep owned = n

Bought 17 sheep = n + 17

Eifion:

Number of sheep owned = 4n

Sells 8 sheep = 4n - 8

Eifion still has more sheep than Rashid.

This means,

4n - 8 > n + 17 ______(1)

Solving for n in (1).

4n - 8 > n + 17

Subtract n on both sides.

4n - 8 - n > n + 17 - n

3n - 8 > 17

Add 8 on both sides.

3n - 8 + 8 > 17 + 8

3n > 25

Divide 3 on both sides,

n > 25/3

n > 8.33

This means n is greater than 8.33.

We can have 9, 10, 11, 12, 13, ,,, and so on.

The least value is 9.

Thus,

The least value of the number of sheep is 9.

Answer:

median is 32 and the mean is 21

Answer:

slope = [tex]-\frac{1}{8}[/tex]

Step-by-step explanation:

Use the slope formula given in the question to solve for the slope. The [tex]m[/tex] is the variable representing the slope. The [tex]x_1[/tex] and [tex]y_1[/tex] values are x and y values of one point. The [tex]x_2[/tex] and [tex]y_2[/tex]  are x and y values of another point.

So, use the x and y values of the points given and substitute them in the correct order into the formula:

[tex]m = \frac{(7)-(9)}{(10)-(-6)}\\m = \frac{7-9}{10+6} \\m = \frac{-2}{16} \\m = -\frac{1}{8}[/tex]

Thus, the slope is [tex]-\frac{1}{8}[/tex].

Answer:

Reference Point

Step-by-step explanation:

The answer is reference point. This is because reference point is used to determine if an object is in motion or if it has changed is direction.

Thus, reference point has to be a value of zero for us to use it to determine if an object has moved.

Answer:

120kg, 72kg and 8kg

Step-by-step explanation:

Given the ratios 15:9:1

total ratio = 15+9+1 = 25

For the ratio of 15

Share = 15/25 * 200

Share = 3000/25

Share = 120kg

For the ratio of 9

Share = 9/25 * 200

Share = 1800/25

Share = 72kg

For the ratio of 1

Share = 1/25 * 200

Share = 200/25

Share = 8kg
