Answer:

[tex]6 \frac{350}{1000}[/tex] Is the answer, if you want it simplified then, [tex]6 \frac{7}{20}[/tex]

Step-by-step explanation:

Answer:

[tex]{ \sf{ \underline{answer \: is \: \: 6 \frac{7}{20} }}}[/tex]

Step-by-step explanation:

Hope you got the idea in previous answer.

[tex]6.350 = \frac{6350}{1000} [/tex]

reduce the fraction by 10:

[tex] = \frac{6350 \div 10}{1000 \div 10} \\ \\ = \frac{635}{100} [/tex]

then reduce it by 5:

[tex] = \frac{635 \div 5}{100 \div 5} \\ \\ = \frac{127}{20} [/tex]

in mixed fraction mode:

[tex] = 6 \frac{7}{20} [/tex]

Answer:

<UOX and <YOZ

Step-by-step explanation:

Adjacent angles are angles that share a common side and vertex. So, find the angles that share one side. In this case, the two sides of the angle <XOY are OX and YO. Remember when naming an angle that it should be one side, the vertex, the last side. So, the 2 adjacent angles are <UOX and <YOZ because they each share one common side and vertex.

Answer:

A. If it snows, then I will do my homework.

Step-by-step explanation:

The word 'inverse' means to twist/reverse the words without changing the actual meaning of the sentence. All options except Option A have changed the meaning of the sentence; hence option A is the correct answer.

Prime factorization is shows you the only way a number can be factored.

Here are some examples:

6 = 2 x 3

(2 and 3 are prime numbers) If you need to, search up a prime chart of numbers. Also prime numbers is technically how small you can get a number.

Here are some more examples:

12 = 2 x 2 x 3

45 = 5 x 3 x 3

now that you see what it looks like, you may be wondering how did factor those out? Well first find a divisible number. lets use this example;

Factor out 42.

first think of your times table, what two numbers get you to 42, I know that 6 times 7 does so now write it out:

42 = 6 x 7

Is this equation done?

No it is not, 6 can still be factored.

What two numbers get you the product of 6?

they are 3 and 2.

Now the final factored out equation looks like this:

42 = 3 x 2 x 7

I hope this helps!

Answer:

13. -2

14. 0

15. 2

16. 0

Step-by-step explanation:

Since the function is originally f(x), you go to wherever the x value is and see what the y value is.

So...

f(2) means go to x = 2 and see that y = -2

Answer:

[tex] - \frac{257171}{268} [/tex]

Step-by-step explanation:

[tex]5672 \div 67 - 12 \times 87 - \frac{1}{4} [/tex]

[tex] \frac{5672}{67} - 12 \times 87 - \frac{1}{4} [/tex]

[tex] \frac{5672}{67} - 1044 - \frac{1}{4} [/tex]

[tex] \frac{22688 - 279792 - 67}{268} [/tex]

[tex] \frac{ - 257171}{268} [/tex]

[tex] = - \frac{257171}{268} [/tex]

Answer:

811 inches is equivalent to 20.5994 meters

811 is also equivalent to 811/1

Answer:

Your question is not complete as you have not mentioned the loan amount ,

As By simple intrest formula ,

A = PRT

we didn't know the principal (loan) amount so you have to pay

A = 0.05P

Explanation:

Let's say there are 1000 boards to be painted.

Working alone, Dan can paint 1000 boards in 10 hours, so his unit rate is 1000/10 = 100 boards per hour.

In 4.12 hours, he gets 4.12*100 = 412 boards painted. There are 1000-412 = 588 boards left which Natalie takes care of. This is when the two are working together.

Her unit rate is (588 boards)/(4.12 hours) = 142.718447 boards per hour. That value is approximate.

We multiply her unit rate by some unknown amount of time x, and this product will be the 1000 boards we started with. This way she would get the job down by herself.

So the equation we need to solve is

142.718447x = 1000

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

We divide both sides by 142.718447 to fully isolate x.

142.718447x = 1000

x = 1000/(142.718447)

x = 7.006803

That value is approximate.

If we round to the nearest whole number, then x = 7

So it takes about 7 hours for Natalie to get the job done if she works alone.

Side note:

An alternative pathway is to solve the equation

1/10 + 1/x = 1/(4.12)

Answer:

The domain of g(x) is the set of all real numbers. Also, g(g(x)) is defined for the set of all real numbers. Therefore, the domain of is the set of gg D all real numbers

Step-by-step explanation:

Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0. We can also define special functions whose domains are more limited

Answer:

1. all of them are in the range

Step-by-step explanation:

Since -1 < x <  4

then  -1 (7) < 7x < 7(4)

- 7 < 7x < 28

-7 + 4 < 7x + 4 < 28  + 4

-3 < 7x + 4 < 32

SInce all the options are within the range between -3 and 32 then the answer is 1.

Answer:

[tex] {x}^{2} + 5x = - 2[/tex]

arrange the equation according to general formula;

General formula: ax² + bx + c = 0

therefore:

[tex] {x}^{2} + 5x + 2 = 0[/tex]

Using the quadratic equation :

[tex]x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ [/tex]

a » 1, b » 5, c » 2

substitute:

[tex]x = \frac{ - 5± \sqrt{ {5}^{2} - (4 \times 1 \times 2) } }{(2 \times 1)} \\ \\ x = \frac{ - 5± \sqrt{17} }{2} [/tex]

therefore solutions are;

[tex]{ \boxed{ \boxed{x_{1} = \frac{ - 5 + \sqrt{17} }{2} }}} \: \: and \: \: { \boxed{ \boxed{x_{2} = \frac{ - 5 - \sqrt{17} }{2} }}}[/tex]

x is -0.438 and -4.562
