Total amount of water before it was drained will be 510 gallons.

"It is a ratio in which the two terms being compared have different units."

For given question,

We have been given  a table for  the number of gallons of water left in the tank after being drained for two amounts of time.

First we find the rate at which the water was drained from the tank.

[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]

Let the amount of water in the tank before it was drained = 'x' gallons

And the initial time = 0

Using the rate formula,

[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]

Therefore, total amount of water before it was drained will be 510 gallons.

Step-by-step explanation:

The evidence "SAY" was only written once. It wasn't by the same article, the writer introduces two separate articles.

Kinda confused by this question but I think that's the answer.

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Given that the two parallel lines are crossed by a transversal line.

Given that

m∠2 = 2x + 54 and m∠6 = 6x - 11

Angle ∠2 and ∠6 are corresponding angles.

Corresponding angles are congruent.

Thus,

m∠2 = m∠6

2x + 54 = 6x - 11

flipe the equation

6x - 11 = 2x + 54

subtract 2x from both sides

6x - 2x - 11 = 2x - 2x + 54

4x - 11 = 54

adding 11 to both sides

4x - 11 + 11 = 54 + 11

4x = 65

dvide both sides by 4

4x/4 = 65/4

x = 16.2500    (round to 4 decimal places)

Part b)

We have already determined

x = 16.2500

Given

m∠2 = 2x + 54

substitute x = 16.2500 in the euation

        = 2(16.2500) + 54

        = 86.5°

As angle ∠2 and angle ∠1 lie on a straight line. Hence, the sum of their angles must be 180°.

i.e.

m∠1 + m∠2 = 180°

substituting m∠2 =  86.5° in the equation

m∠1 + 86.5°  = 180°

subtracting 86.5° from both sides

m∠1 + 86.5° - 86.5° = 180° - 86.5°

m∠1 = 93.5°

Therefore, the measure of angle m∠1 is:

Answer:

A

Step-by-step explanation:

in a right triangle, the longest side (across from the right angle) is the hypotenuse (denoted as 'c')

the legs are denoted as 'a' and 'b'

the Pythagorean Theorem allows you to find the missing side using this formula:

a² + b² = c²

Step-by-step explanation:

8 x 4 is 32

32 x 3 is 96

96 x 2.5 is 240

Answer:

x = 55

Step-by-step explanation:

Since 2 sides of the triangle are congruent, both 5, then the triangle is isosceles and the 2 base angles are congruent, both x , then

x + x + 70 = 180 ← sum of 3 angles = 180°

2x + 70 = 180 ( subtract 70 from both sides )

2x = 110 ( divide both sides by 2 )

x = 55

Answer:

Answer:

x = 20

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

x = [tex]\sqrt{400}[/tex] = 20

Answer:x=√−y2+18y−56 or x=−√−y2+18y−56

Step-by-step explanation:

x2+(y−9)2=25

Step 1: Add -y^2 to both sides.

x2+y2−18y+81+−y2=25+−y2

x2−18y+81=−y2+25

Step 2: Add 18y to both sides.

x2−18y+81+18y=−y2+25+18y

x2+81=−y2+18y+25

Step 3: Add -81 to both sides.

x2+81+−81=−y2+18y+25+−81

x2=−y2+18y−56

Step 4: Take square root.

x=√−y2+18y−56 or x=−√−y2+18y−56

Answer:

x=√−y2+18y−56 or x=−√−y2+18y−56

Answer: Monitor C is the different one.

Step-by-step explanation:

The aspect ratio is the relationship between width and height.

So we only need to see the quotients between width and height for each monitor and see which quotient is different.

Monitor A:  

Quotient = 1152/864 = 1.333....

Monitor B:

Quotient = 800/600 = 1.333...

Monitor C:

Quotient = 1920/1080 = 1.777...

Monitor D:

Quotient = 1600/1200 = 1.333...

We can see that the one with a different aspect ratio is monitor C.
