Answer:

  350

Step-by-step explanation:

The solution to the equation can be found by multiplying by the denominator, then dividing by its coefficient.

  [tex]0.22 = \dfrac{77}{x}\qquad\text{given}\\\\0.22x = 77\qquad\text{multiply by $x$}\\\\x=\dfrac{77}{0.22}=350\qquad\text{divide by the coefficient of x}[/tex]

The missing value in the fraction is 350.

Additional comment

Here, we have rewritten the percentage as a decimal fraction. You could also rewrite it as a ratio of two integer: 22% = 22/100. Sometimes there is confusion about percentages. It can help to think of the % symbol as meaning /100:

  22% = 22/100

Of course, that is "twenty-two hundredths" or 0.22.

If you just write the problem using 22/100 for 22%, then you get the proportion ...

  22/100 = 77/x

  22x = 7700 . . . . . "cross multiply" (multiply by 100x)

  x = 7700/22 = 350 . . . . divide by the coefficient of x

__

If you're paying attention, you see that the solution of this kind of equation has the appearance that the denominator variable and the left-side value are simply swapped:

  [tex]0.22 = \dfrac{77}{x}\ \leftrightarrow\ x=\dfrac{77}{0.22}[/tex]

Effectively, we have multiplied both sides of the equation on the left by x/0.22. There is a property of equality that lets us do that. There is no such thing as a property of equality that says "swap with denominator." You must always pay attention to what is allowed by the properties of equality.

Step-by-step explanation:

5 divided by 5 equals 1 and whatever we do to one side, do to the other. 30 divided by 5 is 6. So, 5 to 30 is equivalent to 1 to 6.

Answer:

330

Step-by-step explanation:

When we are at 30 degrees on the unit circle, we are at the point ([tex]\sqrt3[/tex]/2, 1/2) so if we go to -30 degrees (330 degrees), we will be at point  (-[tex]\sqrt3[/tex]/2, -1/2).

Note: (cosine, sine)

[tex]9y^2-12y-14=0\\D=(-12)^2-4\times9\times(-14)=144+504=648=(\pm18\sqrt{2})^2 \\\\y_1=\dfrac{12+18\sqrt{2} }{18} =\dfrac{2+3\sqrt{2} }{3} \\\\y_2=\dfrac{12-18\sqrt{2} }{18} =\dfrac{2-3\sqrt{2} }{3}[/tex]

Answer:

5

Step-by-step explanation:

You simply just divide 100 by 20 and get your answer which is 5.

When you distribute something, you are dividing it into parts. In math, the distributive property helps simplify difficult problems because it breaks down expressions into the sum or difference of two numbers

Answer:

for a three hour job it would be £105

Step-by-step explanation:

to find how much he charges an hour, we divide 140 by 4 and get 35.

from there we multiply 35(£) by 3(hours) and get 105(£).

Answer:

180m

Step-by-step explanation:

The figure shown in the picture is a right triangle.

We have two of it's sides and need to find the hypotenuse (the side in front of the right angle).

To find that we must use the Pythagorean theorem:

[tex]c^{2} = {a}^{2} + {b}^{2} [/tex]

Side a is 400m and side b is 300m.

Therefore:

[tex]c^{2} = {300}^{2} + {400}^{2} [/tex]

[tex]c = \sqrt{300 \times 300 + 400 \times 400} = 500[/tex]

Now that we know that side c is 500m we must just substract the distance between Marla and the dock with the lenght of the side to find the answer

500 - 320 = 180m

Answer:

She is 180m from the information Center

Answer:

1) [tex]x = -1[/tex]  ||     2) [tex]x = 10[/tex]

Explanation:

1)

→ [tex]\log _3\left(\frac{1}{3}\right)=x[/tex]

→ [tex]\frac{1}{3} = 3^x[/tex]

→ [tex]3^{-1} = 3^x[/tex]

→ [tex]x = -1[/tex]

2)

→ [tex]\log _3\left(x-1\right)=2[/tex]

→ [tex]x - 1 = 3^2[/tex]

→ [tex]x -1 = 9[/tex]

→ [tex]x = 9 +1[/tex]

→ [tex]x = 10[/tex]

[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]

Here's the solution ~

[tex]\qquad \sf  \dashrightarrow \: log_{ {3} }( \frac{1}{3} ) = x[/tex]

[tex]\qquad \sf  \dashrightarrow \: log_{ {3} }( {3}^{ - 1} ) = x[/tex]

[tex]\qquad \sf  \dashrightarrow \: log_{ {3} }( {3})^{ - 1 } = x[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 1 \times log_{3}(3) = x[/tex]

[tex]\qquad \sf  \dashrightarrow \: - 1 \times 1 = x[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = - 1[/tex]

[tex]\qquad \sf  \dashrightarrow \: log_{3}(x - 1) = 2[/tex]

[tex]\qquad \sf  \dashrightarrow \: x - 1 = {3}^{2} [/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 9 + 1[/tex]

[tex]\qquad \sf  \dashrightarrow \: x = 10[/tex]

Answer:

[tex]p=-10[/tex]

Step-by-step explanation:

Given the following question:

[tex]-5=p+5[/tex]

In order to find the answer, we subtract 5 on both sides:

[tex]-5=p+5[/tex]
[tex]5-5=0[/tex]
[tex]-5-5=-10[/tex]
[tex]-10=p[/tex]
[tex]p=-10[/tex]

Answer:

[tex]x=750m[/tex]

Step-by-step explanation:

[tex]Assuming[/tex] [tex]That[/tex]:

[tex]1m=3.3ft[/tex]

We can make the conversion from feet per second to meters per second with this procedure:

[tex](165 \frac{ft}{s} ) (\frac{1m}{3.3ft} )=50\frac{m}{s}[/tex]

Let [tex]x[/tex] be the amount of meters the parachutist will fall during 15 seconds of free fall

Having that in 1 second the parachutist falls 50 meters, we can calculate [tex]x[/tex] :

[tex]x=(50\frac{m}{s} )(15s)[/tex]

[tex]x = 750 m[/tex]

Answer:

32°

Step-by-step explanation:

Let the angle next to 121° be a,

a+121°=180°

a=180-121=59°

Now we have a=59°,

89° (given) and x, these threes form a triangle, therefore,

x+a+89°=180°

×+59°+89°=180°

x+148°=180°

x=180°-148°

x=32°
