∠ ACD = 70°

Step-by-step explanation:

The angle on the circle subtended by arc AB is half the angle at the centre subtended on the same arc, that is

∠ ACD = [tex]\frac{1}{2}[/tex] ∠ AOB = [tex]\frac{1}{2}[/tex] × 140° = 70°

Answer:

Try using slope formula

Step-by-step explanation:

You can use the formula of m= ((y2)-(y1)/((x2)-(x1))

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:

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:

6

Step-by-step explanation:

7 x 6 = 42 + 9 = 51 + 54 = 105 + 75= 180

Answer:

6

Step-by-step explanation:

Tge sum of interior angles in a triangle is equal to 180°

7x + 9 + 54° + 75° = 180° add like terms

7x + 138° = 180° subtract 138 from both sides

7x = 42 divide by 7

x = 6

Answer:

[tex]2.077[/tex] × [tex]10^{-4}[/tex]

Step-by-step explanation:

To convert to scientific notation, you need the number to be less than 10, but greater than 1 and is multiplied by a base of 10 to the power of the number of times you moved the decimal. So you need to shift the decimal place 4 times to the right to get to 2.077 (which is less than 10, but greater than 1). The next part is that you’ll need a base number, which is 10 because your moving the decimal by 10s. Since the decimal is being moved to the right, the exponent will be negative. You moved it 4 times so it’s [tex]10^{-4}[/tex]. The finished answer is:

[tex]2.077[/tex] × [tex]10^{-4}[/tex]

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

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:

Answer:[tex]2^{x}[/tex] = 16

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.
