the rule is y= x/3

Answer:

56

Step-by-step explanation:

0.14 gallons/sec * 50 sec = 7 gallons

There are 8 pints per gallon.

7 gallons * 8 pints/gallon = 56 pints

Given that a running tap dispenses 0.14 gallons of water every second. Using unitary method, 56 pints of water is dispensed after 50 seconds.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Water dispensed every second =  0.14 gallons

Water dispensed after 50 seconds = 0.14 * 50 = 7 gallons = 7 * 8 = 56 pints (1 gallon = 8 pints)

Answer:

21/256 or 0.082 (approx.)

Step-by-step explanation:

4 - 515x + 2 = - 36

or, -515x = -36-2-4

or, 515x = 42 [multiplying with (-1) in both sides]

or, x = 42/515

or, x = 21/256 = 0.082

Answer:

<A = right angle

<B = acute angle

<C = obtuse angle

<D = acute angle

Step-by-step explanation:

Right angle = 90 degrees

Acute angle = less than 90 degrees

Obtuse angle = more than 90 degrees

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

We have,

The quadrilateral ABCD.

There are four angles:

∠A = 90°
∠B = 60°

∠C = 140°

∠D = 70°

An acute angle is an angle whose measure is less than 90 degrees.

An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.

A straight angle is an angle whose measure is 90 degrees.

Using the definition,

∠A = 90°

This is a right angle.
∠B = 60°

This is an acute angle.

∠C = 140°

This is an obtuse angle.

∠D = 70°

This is an acute angle.

Thus,

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

So..ummm kay.....

(20t + 5)° + 15t° = 180° [they form a linear pair]

20t + 5 + 15t = 180

20t + 15t = 180 - 5

35t = 175

t = 175 ÷ 35

t = 5

Answer:

x =51

Step-by-step explanation:

You have to set up an equation according to the info you've been given.

Lets use a variable (x) to represent your unknown number.

  6*x  - 8 = 298  ---- I.

   6x - 8 =298 ----  II. add 8 on both sides

        6x = 306 ---- III. Divide both sides by 6

        x = 51

Answer:

125

Step-by-step explanation:

First, solve the exponent:

5^2 = 5x5 = 25

Then solve the rest:

5x25-125

Answer:

125

Step-by-step explanation:

We need to follow PEMDAS (or BODMAS):

This says that we need to do exponents first, so we'll do the square root of 5, giving us 25.

After this we will multiply 5 by 25, giving us the answer of 125.

*The key point in this problem is using PEMDAS (or BODMAS) correctly.

Answer:

The parallel equation is y=[tex]\frac{5}{2}[/tex]x-5.

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Step-by-step explanation:

First solve for y.

-5x+2y=8

2y=5x+8

y=[tex]\frac{5}{2}[/tex]x+4

A line is parallel if it has the same slope, but different y-intercepts.

The y-intercept of the given point is -5, so the new slope will be y=[tex]\frac{5}{2}[/tex]x-5

To find a perpendicular line, you find the negative reciprocal of the given slope.

So you find [tex]\frac{-1}{\frac{5}{2} }[/tex], which is equal to [tex]\frac{-2}{5}[/tex].

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Answer:

[tex]x=6\\y=12[/tex]

Step-by-step explanation:

To find the value of x you can use sin rule

[tex]sin(60)=\frac{oppoaite}{hypotenuse}\\\frac{\sqrt{3} }{2} =\frac{x}{4\sqrt{3} } \\[/tex]

Use cross multiplication

[tex]4*\sqrt{3} *\sqrt{3} =2x\\4*3=2x\\12=2x\\\frac{12}{2} =\frac{2x}{2} \\6 =x[/tex]

To find the value of y you have to use sin rule again

[tex]sin(30)=\frac{opposite}{hypotenuse}\\\frac{1}{2} =\frac{x}{y} \\\frac{1}{2} =\frac{6}{y} \\[/tex]

Use cross multiplication

[tex]y=6*2\\y=12[/tex]

Step-by-step explanation:

Answer:

x = 3

y = 2

z = -3

Step-by-step explanation:

L1         x + 2y + z = 4

L2      2x - y + 4z = - 8  

L3    - 3x + y - 2z = - 1

2L1 - L2

2x + 4y + 2z = 8

-2x +   y - 4z =  8

------------------------------

         5y - 2z = 16        L4

3L1 + L3

3x + 6y + 3z = 12

-3x +   y  - 2z = -1

-----------------------------

        7y +  z = 11            L5

L4 + 2L5

 5y - 2z = 16

14y + 2z = 22

--------------------------

19y        = 38

y = 38 / 19

y = 2

7y +  z = 11

7(2) + z = 11

14 + z = 11

z = 11 - 14

z = -3

x + 2y + z = 4

x + 2(2) + (-3) = 4

x + 4 - 3 = 4

x + 1 = 4

x = 4 - 1

x = 3

you can also drive -8 to right side to add with 180° if needed !

The ratio of cups of water to cups of flour will make the same recipe are :

8:27, 12 :36, 16:45, 20 : 54, 24 : 63, 28 : 72

Ratio is use to show the frequency with which one number is contained in another number. For example, if for every  boy there are five girls. This information can be expressed as 1 : 5.

The ratio of cups of water to flour is 4 : 9. The ratios that would yield the same recipe are ratios that are multiples of 4 and 9

Multiples of 4 = 4. 8, 12, 16, 20, 24, 28, 32, 36, 40.

Multiples of 9 = 9, 27, 36, 45, 54, 63, 72, 81, 90.

Pairs of ratios equivalent to 4:9 = 8:27, 12 :36, 16:45, 20 : 54, 24 : 63, 28 : 72,
