Answer:

z = 18,9

Step-by-step explanation:

[tex]6.6 = 3(z - 16.9) - - 0.6[/tex]

[tex]6.6 = 3z - 50.7 - ( - 0.6)[/tex]

[tex]6.6 = 3z - 50.7 + 0.6[/tex]

[tex]6.6 = 3z - 50.1[/tex]

[tex]6.6 - 3z = - 50.1[/tex]

[tex] - 3z = - 50.1 - 6.6[/tex]

[tex] - 3z = - 56.7[/tex]

[tex]z = 18.9[/tex]

divide the value in centimeters by 100 because 1 meter equals 100 centimeters.

So, 89.9 centimeters = 89.9÷ 100 = 0.899 meter.

Answer:

b = 9

Step-by-step explanation:

3(b − 6) = 9

3b - 18 = 9

3b = 9 + 18

3b = 27

b = 9

Answer:

b = 9

Step-by-step explanation:

[tex]3(b - 6) = 9[/tex]

[tex]3(b - 6) \div 3 = 9 \div 3[/tex]

[tex]b - 6 = 9 \div 3[/tex]

[tex]b - 6 = 3[/tex]

[tex]b - 6 + 6 = 3 + 6[/tex]

[tex]b = 3 + 6[/tex]

[tex]b = 9[/tex]

Answer:

Step-by-step explanation:

Sin (A +  B) = Sin A *Cos B + Cos A *Sin B

Sin 75 = Sin (30 + 45)

           = Sin 30 * Cos 45 + Cos 30 * Sin 45

           [tex]= \dfrac{1}{2}*\dfrac{1}{\sqrt{2}}+\dfrac{\sqrt{3}}{2}*\dfrac{1}{\sqrt{2}}\\\\\\= \dfrac{1}{2\sqrt{2}}+\dfrac{\sqrt{3}}{2\sqrt{2}}\\\\= \dfrac{1+\sqrt{3}}{2\sqrt{2}}[/tex]

Answer:

y = 5/2 x

Step-by-step explanation:

2m + c = 5

4m + c= 10

__________-

-2m = -5

m = 5/2

c = 0

so, the equation in slope intercept form : y = mx + c

y = 5/2 x + 0

y = 5/2 x

Answer:

y = 5/2 x

Step-by-step explanation:

2m + c = 5

4m + c= 10

__________-

-2m = -5

m = 5/2

c = 0

so, the equation in slope intercept form : y = mx + c

y = 5/2 x + 0

y = 5/2

Answer: Distance = 4√5

Concept:

Here, we need to know the concept of the distance formula.    

The distance formula is the formula, which is used to find the distance between any two points.

If you are still confused, please refer to the attachment below for a clear version of the formula.

Solve:

Given information

(x₁, y₁) = (-8, -4)

(x₂, y₂) = (0, -8)

Given equation

[tex]Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substitute values into the equation

[tex]Distance=\sqrt{(0+8)^2+(-8+4)^2}[/tex]

Simplify values in the parentheses through addition

[tex]Distance=\sqrt{(8)^2+(-4)^2}[/tex]

Simplify exponents

[tex]Distance=\sqrt{64+16}[/tex]

Simplify by addition

[tex]Distance=\sqrt{80}[/tex]

Simplify the radical value into the simplest form

[tex]Distance=4\sqrt{5}[/tex]

Answer:

3/35

Step-by-step explanation:

total bottles 7/7

4/7 are big,

7/7-4/7=3/7 remaining bottles.

4/5×3/7=12/35 are small.

you add the big bottles and small bottles

4/7+12/35=32/35

then you minus from the total which is 7/7

7/7-32/35=3/35 are tiny.

Step-by-step explanation:

Answer:

x = -2 —> y = 4

x= 0 —> y = 1

x= 3 —> y = 1/8

Step-by-step explanation:

[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ - 2} =( \frac{2}{1} ) ^{2} = {2}^{2} = 4[/tex]

[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ 0} =1[/tex]

[tex]y = ( \frac{1}{2} ) ^{x} \\ y = ( \frac{1}{2} ) ^{ 3} = \frac{ {1}^{3} }{ {2}^{3} } = \frac{1}{8} [/tex]

Answer:

We have to use addition or subtraction property of equality to determine the value of variable involve.

Step-by-step explanation:

Example with variable term:

3x=4-x

Add x on both sides of equation:

3x+x=4-x+x

4x=4

x=1

Example with contact involve:

5y+7=12

Subtract 7 from both sides

5x+7-7=12-7

5x=5

x=5/5

x=1

Step-by-step explanation:

½(f + y) = f - 5

(f + y)/2 = f - 5

y + f = 2f - 10

y = f - 10

or

f = y + 10

#mathisfun

Answer:

Let 'a' be the first term, 'r' be the common ratio and 'n' be the number of terms

Series = 2+6+18.......= 2+2•3¹+ 2•3².......= 728

Now,

[tex]Sum = \frac{a( {r}^{n} - 1) }{(r - 1)} \\ [/tex]

So,

[tex] \frac{a( {r}^{n} - 1)}{(r - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{(3 - 1)} = 728 \\ \frac{2( {3}^{n} - 1) }{2} = 728 \\ {3}^{n} - 1 = 728 \\ {3}^{n}=728+1\\ {3}^{n} = 729 \\ {3}^{n} = {3}^{6} \\ \boxed{ n = 6}[/tex]

Therefore, number of terms is 6

Its a GP given by 2+6+18

Common ratio=r=

[tex]\\ \bull\tt\looparrowright \dfrac{6}{2}=3[/tex]

Now

[tex]\\ \bull\tt\looparrowright S_n=728[/tex]

[tex]\\ \bull\tt\looparrowright \dfrac{a(r^n-1)}{r-1}=728[/tex]

[tex]\\ \bull\tt\looparrowright \dfrac{2(3^n-1)}{3-1}=728[/tex]

[tex]\\ \bull\tt\looparrowright \dfrac{2(3^n-1)}{2}=728[/tex]

[tex]\\ \bull\tt\looparrowright 3^n-1=728[/tex]

[tex]\\ \bull\tt\looparrowright 3^n=728+1[/tex]

[tex]\\ \bull\tt\looparrowright 3^n=729[/tex]

[tex]\\ \bull\tt\looparrowright 3^n=3^6[/tex]

[tex]\\ \bull\tt\looparrowright n=6[/tex]

Answer:

See below.

Step-by-step explanation:

There are 2 options in finding the difference between f and 35, as you did not state in the question which if the 2 is the larger number.

(f-35)-5=f-35-5

=f-40

OR

(35-f)-5=35-f-5

=30-f

0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.

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

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Event A: Your friend wins the first prize.

Event B: You win the second prize.

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

Probability friend wins first prize:

10 out of 100 tickets, so:

[tex]P(A) = \frac{10}{100}[/tex]

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

Probability you win second prize:

There will be 99 tickets remaining(1 has been sorted), you have then of then, so:

[tex]P(B) = \frac{10}{99}[/tex]

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

What is the probability that your friend wins the first prize and you win the second prize?

Multiplication of the probabilities, thus:

[tex]p = P(A) \times P(B) = \frac{10}{100} \times \frac{10}{99} = \frac{10\times10}{100\times99} = 0.0101[/tex]

0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.

Answer:

below

Step-by-step explanation:

First we need to find the domain.

x^2+ y^2 = 8

√x^2 + √y^2 = √8

x + y = ±2√2

So the domain is ±2√2. If you graph the circle you will see that it will in fact fail the vertical line test, mainly because its a circle. If you graph the domain onto the circle, you will see that it will have an affect on it being a relation. A graph will be shown below for a better reference. Keep in mind that ±2.828 is the decimal form of ±2√2.
