Step-by-step explanation:

its correct!

The answer is : p = -4

the following are the steps to solve it::

13 - 3p = -5 (3 + 2p)

calculate the area of the right hand first by multiplying the number 5 by the number in brackets

13 - 3p = -15 - 10p

move everything that contains p to the left side

13 - 3p + 10p = - 15

count all containing p

13 + 7p = -15

move the ones that don't contain p to the right

7p = -15 - 13

count on the right side

7p = - 28

p = -4

Answer:

$25940

Step-by-step explanation:

Future value of an Investment at r% for n years is given by:

Future Value = Initial Investment (1 + r/100)n

If r = 10% and n = 10 years

Future Value = 10000(1 + 10/100)10

= 10000(1.1)10

= 10000(2.594)

= $ 25940

Hence the required value is $ 25940.

Step-by-step explanation:

[tex] \frac{ - 10 + r}{2} \geqslant - 13[/tex]

multiply both sides by 2:

[tex] - 10 + r \geqslant - 26[/tex]

add 10 on both sides:

Answer:

[tex]r \ge -16[/tex]

Step-by-step explanation:

To solve any equation/inequality:

1. get the variable to show up exactly once

2. isolate it

[tex]\frac{-10+r}{2} \ge -13[/tex]

Multiply both sides by 2 and simplify (note that we're multiplying by a positive, not a negative, so the direction of the inequality stays the same, whereas multiplying or dividing by a negative would have changed the direction of the inequality)

[tex]\frac{-10+r}{2} *2 \ge -13 *2[/tex]

Add 10 to both sides, and simplify

Using the proportion rule, the ratios 1/3 and 2/5 does not form a proportion.

In the given equation,

We have to check the ratios 1/3 and 2/5 form a proportion or not.

As we know that proportion is a ratio in which both ratios are equal to each other.

So to check whether the given statement is proportion or not we put both equation equal to each other.

So the ratios are 1/3 and 2/5.

Now checking the proportion.

1/3=2/5

Multiply by 15 on both side.

1/3 ×15=2/5 ×15

Simplifying

Answer:

50m/s = (50 ÷ 1000 × 60 × 60)km/h

           = 180km/h

Step-by-step explanation:

We know rhat

[tex] \sin( \frac{x}{2} ) = \sqrt{ \frac{1 - \cos(x) }{2} } [/tex]

whenever x lies from 90 to 180.

If

[tex] \csc(x) = 9[/tex]

Using Reciprocal Identities

[tex] \sin(x) = \frac{1}{9} [/tex]

Using Pythagorean Identity,

[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]

[tex]( \frac{1}{9} ) {}^{2} + \cos {}^{2} (x) = 1[/tex]

[tex] \cos {}^{2} (x) = \frac{80}{81} [/tex]

[tex] \cos(x) = \frac{4 \sqrt{5} }{9} [/tex]

Cosine is negative in when x lies between 90 and 180 so

[tex] \cos(x) = - \frac{4 \sqrt{5} }{9} [/tex]

So

[tex] \sin( \frac{x}{2} ) = \sqrt{ \frac{1 + \frac{4 \sqrt{5} }{9} }{2} } [/tex]

[tex] \sin( \frac{x}{2} ) = \sqrt{ \frac{9 + 4 \sqrt{5} }{18} } [/tex]

For cosine remember

[tex] \cos( \frac{x}{2} ) = \sqrt{ \frac{1 + \cos(x) }{2} } [/tex]

Cosine is negative in second quadrant so

[tex] \cos( \frac{x}{2} ) = - \sqrt{ \frac{1 + \cos(x) }{2} } [/tex]

[tex] \cos( \frac{x}{2} ) = - \sqrt{ \frac{1 - \frac{4 \sqrt{5} }{9} }{2} } [/tex]

[tex] \cos( \frac{x}{2} ) = - \sqrt{ \frac{9 - 4 \sqrt{5} }{18} } [/tex]

For tangent,

[tex] \tan( \frac{x}{2} ) = \frac{ \sin( \frac{x}{2} ) }{ \cos( \frac{x}{2} ) } [/tex]

[tex] \frac{ \sqrt{ \frac{1 - \cos(x) }{2} } }{ \sqrt{ \frac{1 + \cos(x) }{2} } } [/tex]

[tex] = \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } [/tex]

Tangent is negative over 90<x<180 so

[tex] - \frac{ \sqrt{1 - \cos(x) } }{ \sqrt{1 + \cos(x) } } [/tex]

[tex] - \sqrt{ \frac{1 + \frac{4 \sqrt{5} }{9} }{1 - \frac{4 \sqrt{5} }{9} } } [/tex]

[tex] - \sqrt{ \frac{ \frac{9 + 4 \sqrt{5} }{9} }{ \frac{9 - 4 \sqrt{5} }{9} } } [/tex]

[tex] - \sqrt{ \frac{9 + 4 \sqrt{5} }{9 - 4 \sqrt{5} } } [/tex]

[tex] - \sqrt{ \frac{1}{(9 - 4 \sqrt{5) {}^{2} } } } [/tex]

[tex] - \frac{1}{9 - 4 \sqrt{5} } [/tex]

so

[tex] \tan( \frac{x}{2} ) = - \frac{1}{ 9 + 4 \sqrt{5} } [/tex]

or

[tex] \tan( \frac{x}{2} ) = - 9 + 4 \sqrt{5} [/tex]

Answer:

A ................................

24 ounces of a 15% alcohol solution must be mixed with 16 ounces of a 20% alcohol solution to make a 17% alcohol solution.

Let x ounces of 15% alcohol must be mixed with the 16 ounces of 20% alcohol.

The amount of alcohol in 16 ounces solution is = (20/100) * 16 ounces

                                                                              = 3.2 ounces

The amount of alcohol in x ounces  solution is = (15/100) * x

                                                                              = 0.15x ounces

Total amount of alcohol is = (16 + x) ounces

According to the problem we get an equation,

(3.2 + 0.15x)/(16 + x) = 17/100

100(3.2 + 0.15x) = 17(16 + x)

320 + 15x = 272 + 17x

320 - 272 = 17x - 15x

48 = 2x

x = 48/2

x = 24

Therefore, 24 ounces of a 15% alcohol solution must be mixed with 16 ounces of a 20% alcohol solution to make a 17% alcohol solution.

Therefore, p has an equation of y = 5 / 3 x - 4 Line q includes the point (-10,-3) and is perpendicular to line p.  The equation of line q can be found as follows:

The product of the slope of perpendicular lines is equals to negative one.

Therefore, let's find the slope of line q.

m₁m₂ = -1

5 / 3m₂ = - 1

m₂ = - 3 / 5

Hence, the equation of line q is y = - 3 / 5x + b.

In the scientific notation, the total population of Brazil and Lithuania is 2.02255 x 10⁸

Scientific notation

A method of expressing numbers in terms of a decimal number between 1 and 10 multiplied by a power of 10 is known as Scientific notation.

Given,

In 2010, the population of Brazil was about 1.987 x 10⁸ people. The population of Lithuania was about 3.555 x 10⁶ people.

Here we need to find the total population of Brazil and Lithuania and expression the value in scientific terms.

Here we know that,

Population of Brazil = 1.987 x 10⁸

Population of Lithuania = 3.555 x 10⁶

In order to find the total population, first we have to make the exponent of the two value as equal,

For that we have to rewrite the population of Brazil as,

Population of Brazil = 198.7 x 10⁶

Now, we have to add the two population count in order to find the total population,

=> (198.7 x 10⁶) + (3.555 x 10⁶)

Take the exponent term as common,

=> (198.7 + 3.555) x 10⁶

=> 202.255 x 10⁶

Now, we have to move the two decimal point to simplify this one, then we get,
