Solve z=sh/s+h for s

Answers

Answer:

[tex]\displaystyle s = \frac{hz}{h-z}[/tex]

Step-by-step explanation:

We are given the equation:

[tex]\displaystyle z = \frac{sh}{s+h}[/tex]

And we want to solve it for s.

First, we can multiply both sides by the denominator:

[tex]\displaystyle z(s+h) = sh[/tex]

Distribute:

[tex]\displaystyle sz + hz = sh[/tex]

Subtract hz and sh from both sides:

[tex]\displaystyle sz - sh = -hz[/tex]

Factor:

[tex]\displaystyle s(z-h) = -hz[/tex]

And divide. Hence:

[tex]\displaystyle s = \frac{-hz}{z-h} = - \frac{hz}{z-h} = \frac{hz}{h-z}[/tex]

Any one of the above three forms are correct, although the third form is preferred because it omits the additional negative.

I have no idea how to find multiple angles i was only taught how to find one..

Answers

The sum of all angles must equal 180°. Since you already have two angles for the larger triangle, all you need to do to find m < x is by subtracting m < 63° and m < 36° from 180°:

m < x = 180° - m < 63° - m < 36°
m < x = 81°

Therefore, < x = 81°

For the smaller triangle (acute), what you could do to find m < z is by subtracting m < x from 180°. We can do it that way because < x and < z are supplementary angles whose sum add up to 180°.

m < z = 180° - m < x
m < z = 180° - m < 81°
m < z = 99°

Therefore, < z = 99°

Lastly, to find m < y, subtract m < 13°and m < z° from 180°:

m < y = 180° - m < z° - m < 13°

m < y = 180° - m< 99° - m< 13°
m < y = 68°


Therefore, the measure of the following angles are:

< x = 81°
< y = 68°
< z = 99°

Answer:

36+63+_=180

Step-by-step explanation:

just add up everything in the smaller triangle to get 180

then ignore the line inside of the bigger triangle and repeat the first step, but only just look at the bigger one! that is how to do it, but I won't give the answer, good luck! ;)

Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.​

Answers

[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]

The values of :

[tex]x = 2[/tex]

[tex]y = 3[/tex]

The given equations are :

[tex]0.4x + 0.3y = 1.7[/tex]

[tex]0.7x - 0.2y = 0.8[/tex]

now, let's multiply both the equations with 10 on both sides.

so, now our equations will be :

[tex]4x + 3y = 17[/tex]

[tex]7x - 2y = 8[/tex]

from Equation second :

[tex]7x - 2y = 8[/tex]

[tex]2y = 7x - 8[/tex]

[tex]y = \dfrac{7x - 8}{2} [/tex]

now, let's substitute the value of y from here into Equation first.

[tex]4x + 3y = 17[/tex]

[tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex]

[tex]4x + \dfrac{21x - 24}{2} = 17[/tex]

[tex] \dfrac{8x + 21x - 24}{2} = 17[/tex]

[tex] \dfrac{ 29x - 24 }{2} = 17[/tex]

[tex]29x - 24 = 34[/tex]

[tex]29x = 34 + 24[/tex]

[tex]29x = 58[/tex]

[tex]x = \dfrac{58}{29} [/tex]

[tex]x = 2[/tex]

here, we got the value of x = 2, let's plug it in equation second to find value of y :

[tex]7x - 2y = 8[/tex]

[tex]7(2) - 2y = 8[/tex]

[tex]14 - 2y = 8[/tex]

[tex]2y = 14 - 8[/tex]

[tex]2y = 6[/tex]

[tex]y = \dfrac{6}{2} [/tex]

[tex]y = 3[/tex]

And value of y = 3

George practises his guitar for 1 1/5 hours per day on school days. On Saturday he increases to 2 1/2 times his normal time. How many hours does he practice on Saturdays.

Answers

Answer: 231/10

Step-by-step explanation: 11/5 x 21/2

= (11 x 21) = 231  

= 231/5 x 2

=  231/10

Answer:

3 hours

Step-by-step explanation

It would be easier to convert your fractions into decimals.

1/5 is the same as 2/10.  Since the denominator was multiplied by 2 then the numerator must be multiplied by 2 also.

2/10 in decimal form is 0.2

He would practice 1.2 hours per day on school days

On Saturday his practice is 2 1/2 times longer than 1.2 hours.

Convert 1/2 into decimal form. 1/2 is the same as 0.5.

So 2 1/2 is the same as 2.5

If you multiply the original time (1.2 hours) by 2.5, you'll know how long he practices on Saturday.

1.2 x 2.5  = 3 hours.

    1.2

 x 2.5

  -------

     60

   24  

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

   300          

since you have 1 decimal place in the top number and 1 decimal in the bottom number, you must move your decimal 2 places to the left on your answer.  Instead of 300, your answer becomes 3.00

Which graph represents the solution to the inequality? 4v - 2 < 10

Answers

Answer:

Option C.

Step-by-step explanation:

First, simplify the inequality. Add 2 to both sides:

4v - 2 < 10

4v - 2 + 2 < 10 + 2

4x < 12

Divide both sides by 4:

4x ÷ 4 < 12 ÷ 4

x < 3

As 3 will not satisfy the inequality, it is not a solution. The option that shows x being less than 3 but not including is option C.

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time

Answers

The maximum distance between them is the diameter of the circle, which is of 44 units.

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

The diameter is twice the radius, and is the maximum distance between two points on the same circle.

They are running on a circular path, modeled by:

[tex]x^2 + y^2 - 10x - 18y = 378[/tex]

Completing the squares, the equation is:

[tex](x - 5)^2 + (y - 9)^2 = 378 + 5^2 + 9^2[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]

[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]

Then, the radius is: [tex]\sqrt{484} = 22[/tex], which means that the maximum distance between the runners at any given time is of 44 units.

Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.

x=4

Statements Reasons

1. 3x – 7 = 5 Given

2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)

3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)

4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)

5. 3x = 12 Substitution of 5 + 7 = 12 into (4)

6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3

7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)

8. x = 4 Substitution of 12⁄3 = 4 into (7)
