Answer:

(1+7v) (3u+8b)

Step-by-step explanation:

Hope this helps!!

The required solution would be (1+7v)(3u+8b) of the given expression.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given the expression as:

⇒ 21uv + 8b + 3u + 56bv

There is v common in 21uv and 56bv

There is b common in 8b and 56bv

There is u common in 21u and 3u

We have to Add and subtract the second term to the expression and factor by grouping, we get

⇒  (1+7v)(3u+8b)

Therefore, the required solution would be (1+7v)(3u+8b) of the given expression.

Answer:

Vertical angles are always congruent.

Step-by-step explanation:

Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.

Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:

<a and <b,

<c and <d.

Thus, <a is congruent to <b, and <c is congruent to <d.

Therefore, the standby that is true about vertical angles is that:

Vertical angles are always congruent.

Step-by-step explanation:

Answer:

f(x)= 12x   where x is the number of hours worked (only whole numbers)

Domain= {10,11,12,13,.............., 25}

Range = { $ 120, $ 132,  $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228,        $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}

Step-by-step explanation:

Let x be the number of hours worked then the function will be

f(x)= 12 (x)       for {x=10,11,12,13,.............., 25}

x cannot taken any fractional value or decimal value.

The domain of the function is the input values

Domain= {10,11,12,13,.............., 25}

Now range of the function is the set of all possible output values

f(10)= 12 *10= $ 120

f(11)=  12 *11= $ 132

f(12)=  12 *12= $ 144

f(13)=  12 *13= $ 156

f(14)=  12 *14= $ 168

f(15)=  12 *15= $ 180

f(16)=  12 *16= $ 192

f(17)=  12 *17= $ 204

f(18)=  12 *18= $ 216

f(19)=  12 *19= $ 228        

f(20)=  12 *20= $ 240

f(21)=  12 *21= $ 252

f(22)=  12 *22= $ 264

f(23)=  12 *23= $ 276

f(24)=  12 *24= $ 288

f( 25) = 12*25= $ 300

Range = { $ 120, $ 132,  $ 144,$ 156 ,$ 168, $ 180, $ 192, $ 204, $ 216, $ 228,        $ 240, $ 252, $ 264, $ 276, $ 288, $ 300}

Answer:

  XL = 13 cm, m∠L = 29°

  AC = 21 cm, m∠C = 29°

  PC = 13 cm, m∠Y = ??  (there is no angle Y in the figure)

Step-by-step explanation:

The figure on the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.

  PA = PC = XL = XN = 13 cm

In the same fashion, ...

  LN = AC = 21 cm

__

Of course, the angles have a similar relationship:

  ∠A = ∠C = ∠L = ∠N = 29°

The two base angles in the triangle add to 58°, so the third angle is ...

  180° -58° = 122°

  ∠P =∠X = 122°

_____

Additional comment

As is often the case in over-specified problems, the numbers shown are not consistent The attached figures show the length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified. What this means is that the answers you get will depend on how you work the problem. Above, we have taken the given numbers and relationships at face value, even though we know they are incorrect.

Answer:

The man's income by the 20th week will be Rs. 1770

Step-by-step explanation:

Given that the income of man in first week is Rs. 60

It is also mentioned that the income increases every week then the previous one.

which means the weekly incomes will be like:

60,63,66,69.....

As the common difference of terms is same i.e. 3, it forms an arithmetic sequence.

Where

[tex]a_1 = 60\\d = 3[/tex]

The general formula for arithmetic sequence is:

[tex]a_n = a_1+(n-1)d[/tex]

Putting the values of d and a_1 we get

[tex]a_n = 60+(n-1)(3)\\a_n = 60+3n-3\\a_n = 57+3n[/tex]

This is the general formula to find the income of any week. Now for 20th week,

n = 20

[tex]a_{20} = 57+(20)(3)\\a_{20} = 57+60\\a_{20} = 117[/tex]

The income for 20th week is 117.

As we have to find the total income for 20 weeks

We will use the summation formula for arithmetic sequence.

[tex]S_n = \frac{n}{2}(a_1+a_{20}})[/tex]

Putting the values

[tex]S_n = \frac{20}{2}(60+117}\\S_n = 10(177}\\S_n = 1770\ Rs.[/tex]

Hence,

The man's income by the 20th week will be Rs. 1770

I hope this helps

Well, it's really simple actually. You don't need to focus on all those extra words on the top, focus on days and swings

In 20 days, Carmen swings 10 times.

In 10 days, Carmen swings 5 times.

If you notice, Y is multipled 0.5 of the original, so half

This means, 1 day (X) is swung 0.5 (Y)

I think Carmen is a possesed little girl for pulling that off

Answer:

p = (3b + 7)/2

General Formulas and Concepts:

Pre-Algebra

Step-by-step explanation:

Step 1: Define equation

3b = 2p - 7

Step 2: Solve for p

And we have our final answer!

Step-by-step explanation:

3b = 2p - 7

make p stand alone

3b + 7 = 2p

dividing both sides by 2

p = (3b + 7)/2

Answer:

24,360 meters per second

Step-by-step explanation:

The average speed = 24.36 kilometer per second

We were asked to convert this to meters per second

1 kilometre = 1000 metres

Hence

24.36km/s = 24.36 × 1000 meters/seconds

= 24,360 meters/seconds.

The average speed of the asteroid is 24,360 meters/seconds.

Answer:

24,360 meters per second

Step-by-step explanation:

The speed of first hiker is 4 mph and speed of second hiker is 5 mph.

Let the speed of first hiker is x mph.

Since If one walks at a rate that is 1 mph faster than the other .

so taht speed of second hiker = (x + 1) mph

It is given that, pair of hikers are 18 miles apart and they meet 2 hours later .So that,

                  2x + 2(x + 1) = 18

                       2x + 1 = 9

                       2x = 9 - 1 = 8

                      x = 8/2 = 4

Hence, the speed of first hiker is 4 mph and speed of second hiker is 5 mph.
