Answer:

15 gallons

Step-by-step explanation:

Given that:

Pumping rate is modeled by the equation :

Q(t)=45-t gallons per minute ; where t is in minutes

Number of gallons in tank after 30 minutes ;

Q(t)=45-t

Q(30) = 45 - 30

Q(30) = 15

Hence, Number of gallons in tank after 30 minutes is 15 gallons

Step-by-step explanation:

The answer is Changes made to your input should not affect the solution:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 2x-15y-35

 ————————— • 5 = 0 • 5

     5    

Now, on the left hand side, the  5  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  2x-15y-35  = 0

Equation of a Straight Line

4.2     Solve   2x-15y-35  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  2x-15y-35  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 7/-3 so this line "cuts" the y axis at y=-2.33333

 y-intercept = 35/-15 = 7/-3  = -2.33333

Calculate the X-Intercept :

When y = 0 the value of x is 35/2 Our line therefore "cuts" the x axis at x=17.50000

 x-intercept = 35/2  = 17.50000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -2.333 and for x=2.000, the value of y is -2.067. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.067 - (-2.333) = 0.267 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  0.267/2.000 =  0.133

Geometric figure: Straight Line

 Slope = 0.267/2.000 = 0.133

 x-intercept = 35/2 = 17.50000

 y-intercept = 35/-15 = 7/-3 = -2.33333

Answer:

if it asking for the type of angle the both are obtuse and the fisrt measure is 135 and the second is 101

Step-by-step explanation:

The relation between 135 and x is corresponding angles.

The value of x is 135 degree.

because the corresponding angles are equal.

Answer:

The ladder is 8 feet high up on the wall.

Step-by-step explanation:

Let the height up of the ladder on the wall be represented by h. The ladder leaning on the wall, wall and distance of the foot of ladder from the wall form a right angled triangle.

So, applying the Pythagoras theorem;

[tex]/hyp/^{2}[/tex] = [tex]/adj 1/^{2}[/tex] + [tex]/adj 2/^{2}[/tex]

[tex]/10/^{2}[/tex] = [tex]/6/^{2}[/tex] + [tex]/h/^{2}[/tex]

100 = 36 + [tex]h^{2}[/tex]

so that,

[tex]h^{2}[/tex] = 100 - 36

   = 64

⇒ h = [tex]\sqrt{64}[/tex]

      = 8 feet

The ladder is 8 feet high up on the wall.

Answer:

s  =  7.811  ¯  6

Step-by-step explanation:

x =  2  + 4  +  5  +  6  +  7  +  9  +  10 /7

¯ x = 43 /7

s = ( 2 − 6.1 ) 2 + ( 4 − 6.1 ) 2 + ( 5 − 6.1 ) 2 + ( 6 − 6.1 ) 2 + (7 − 6.1 ) 2 + ( 9 − 6.1 ) 2 + ( 10 − 6.1 ) 2/ 7 − 1

Answer:

1. You can look at side measurements. Angle measurements will not change so do not use them as reference. For example, if a rectangle has one side as 7 and the other 3, then the scale factor of a rectangle with a side of 21 and 9 would be 3, because 21÷7 is 3 or 9÷3 is 3.

2. You can determine a polygon is similar by having the same angles and/or similar sides.

3. All you need is one side and one angle if the angle and side are opposit each other, so a and A or b and B or c and C. If this is not represented in a problem then you can use 2 angles and 1 side or 1 angle and 2 sides to figure out if they are similar.

Answer:

Step-by-step explanation:

It would take 11 months of membership for the total money paid to each club to be the same.

An equation is an expression that shows the relationship between two or more numbers and variables.

A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.

Let x represent the number of months subscribed. Hence,

For Roman's gym:

Total payment = 25x + 49.99

For Athens Fitness:

Total payment = 18x + 126.99

For both clubs to have the same payment:

25x + 49.99 = 18x + 126.99

7x = 77

x = 11

It would take 11 months of membership for the total money paid to each club to be the same.

Step-by-step explanation:

Answer:

The original length of the new candle is 10 inches

Step-by-step explanation:

The form of the linear function is y = m x + b, where

∵ L represents the length of the candle remeaning unburned in inches

∵ t represents the time after the candle was lit in hours

∵ The relationship between L and t is linear

→ Put it in the form of the equation above

∴ L = m t + b, where b is the original length of the new candle

→ Use the table to find m

∵ m = [tex]\frac{L2-L1}{t2-t1}[/tex]

∵ (1, 9) and (6, 4) are two points in the given table

∴ t1 = 1 and L1 = 9

∴ t2 = 6 and L2 = 4

→ Substitute them in the rule of m above

∵ m = [tex]\frac{4-9}{6-1}[/tex] = [tex]\frac{-5}{5}[/tex] = -1

∴ m = -1

→ Substitute it in the equation above

∵ L = -1(t) + b

∴ L = -t + b

→ To find b substitute t by 1 and L by 9

∵ 9 = -(1) + b

∴ 9 = -1 + b

→ Add 1 to both sides

∵ 9 + 1 = -1 + 1 + b

∴ 10 = b

∵ b is the original length of the new candle

∴ The original length of the new candle is 10 inches

Here it is:

"sqrt 119"

Step-by-step explanation:

in a right triangle, the longest leg is called the hypotenuse. To find the missing side, you need to use the Pythagorean theorem.

"a^2+b^2=c^2"

c = the hypotenuse

a and be are the other legs.

plug in the numbers.

5^2+b^2 = 12^2

25 + b^2 = 144

b^2 = 119

b = 10.98 (approximately)

Answer:

x>-99/4

Step-by-step explanation:

Step-by-step explanation:

m= 2

x1 = -6

y1 = 3

Applying the formula,

y-y1 = m(x-x1);

we have,

y - 3 = 2(x -(-6))

y- 3 = 2(x + 6)

y - 3 = 2x + 12

y -2x -3 -12 = 0

y -2x -15 = 0

Therefore the equation of the line is;

2x - y + 15 = 0
