Find the area of the figure. 3 in 3 in 2 in 9 in

Answer:

3/8

Step-by-step explanation:

If 1 and 3 are odd numbers then all you have to do is count the number of 1 and 3's(3). then count the number of numbers (8).

Answer:

17

Step-by-step explanation:

12 1/2-(-4 1/2)

12 1/2+ 4 1/2

17

Step-by-step explanation:

(x-2)^2

(x-2) (x-2)

x(x-2) -2(x-2)

x^2- 2x -2(x-2)

x^2-4x+4

Answer:

56

Step-by-step explanation:

area of whole figure=

l×b

=20×10

=200

also,area of small fig.

=l×b

=18×8

=144

thus area of shaded part =a of whole- a of small

=200-144

=56

Answer:

Multiyply all 3 numbers to get your answer.

Step-by-step explanation:

4.5*2*2

Answer: 1st one is 18

second one is 44

Step-by-step explanation:

2*2*4.5=18

A=2(wl+hl+hw)=2·(2·4.5+2·4.5+2·2)=44

Answer:

Step-by-step explanation:

Answer:

A. The value of n can be any positive integer resulting in the same factor

Step-by-step explanation:

Given

[tex]x^2 + 2xn + n^2[/tex] --- the right expression

[tex]n > 0[/tex]

Required

Possible values of n

[tex]x^2 + 2xn + n^2[/tex]

Expand

[tex]x^2 + 2xn + n^2 = x^2 + xn+xn + n^2[/tex]

Factorize

[tex]x^2 + 2xn + n^2 = x(x + n)+n(x + n)[/tex]

Factor out [tex]x + n[/tex]

[tex]x^2 + 2xn + n^2 = (x + n)(x + n)[/tex]

From the expression above, we can see that the result has the same factor. This means that options (b), (d) and (e) are not possible

[tex]x^2 + 2xn + n^2 = (x + n)^2[/tex]

The above also shows that n can take any positive value.

Hence: (a) is correct

Answer:

8th term- 6,561

Step-by-step explanation:

Each term in the sequence is being multiplied by 3. For example, 3x3=9 and 9x3=27. Now, we need to continue multiplying numbers, so we can list them all here, still starting with 3.

1&2) 3x3=9

3) 9x3=27

4) 27x3=81

5) 81x3=243

6) 243x3=729

7) 729x3=2,187

8) 2,187x3=6,561

The 8th term of the geometric sequence is 6,561.

Hope this helps and have a great day! ^^

Answer:

60 meters and 176 meters, together it is 236 meters

Step-by-step explanation:

Answer:

$ 1267.

Step-by-step explanation:

Given :

David's monthly income after tax = $ 1430.15

His health insurance cost him in a month = $ 63

Percent deducted from his income after tax for his retirement option is = 7%

Therefore money left after retirement option deduction is :

$ 1430.15 - 7% of $ 1430.15

= 1430.15 - 100.11

= $ 1330.04

= $ 1330 (aprrox)

Money deducted from this amount for his health insurance plan

= $ 1330 - $ 63

= $ 1267

Therefore, David's monthly take home pay is $ 1267.

Answer:

250 $3 tickets and 100 $2 tickets were sold

Answer:

8 meters per second

Step-by-step explanation:

K = v²/2

Given:

K = 32

Solve for v:

K = v²/2

32 = v²/2

v² = 64

[tex]\sqrt{v^2} =\sqrt{64}[/tex]

v = 8

Answer:

a) [tex]\sin 38.582^{\circ} \approx 0.624[/tex], b) [tex]\cot 45.567^{\circ}\approx 0.980[/tex], c) [tex]\sec 39^{\circ} = 1.287[/tex], d) [tex]\tan 12^{\circ} \approx 0.213[/tex], e) [tex]\csc 16.4^{\circ} \approx 3.542[/tex], f) [tex]\sin 34.5^{\circ}\approx 0.566[/tex]

Step-by-step explanation:

Sabemos que un minuto equivale a [tex]\frac{1}{60}[/tex] de un grado sexagesimal, mientras que un segundo equivale a [tex]\frac{1}{3600}[/tex] de un grado sexagesimal, entonces procedemos a convertir cada ángulo a su forma decimal y simplificamos en términos de senos y cosenos mediante identidades trigonométricas:

a) [tex]\sin 38^{\circ}34'56'' = \sin 38.582^{\circ}[/tex]

Por tablas trigonométricas tenemos que [tex]\sin 38^{\circ} \approx 0.616[/tex] y [tex]\sin 39^{\circ} \approx 0.629[/tex], mediante interpolación lineal tenemos que:

[tex]\sin 38.582^{\circ} \approx 0.624[/tex]

b) [tex]\cot 45^{\circ} 34' = \cot 45.567^{\circ}[/tex]

[tex]\cot 45.567^{\circ} = \frac{\cos 45.567^{\circ}}{\sin 45.567^{\circ}}[/tex]

Por tablas trigonométricas tenemos que [tex]\sin 45^{\circ} \approx 0.707[/tex], [tex]\sin 46^{\circ}\approx 0.719[/tex], [tex]\cos 45^{\circ}\approx 0.707[/tex] y [tex]\cos 46^{\circ}\approx 0.695[/tex], mediante interpolación lineal tenemos que:

[tex]\cot 45.567^{\circ}\approx 0.980[/tex]

c) [tex]\sec 39^{\circ} = \frac{1}{\cos 39^{\circ}}[/tex]

Por tablas trigonométricas tenemos que [tex]\cos 39^{\circ}\approx 0.777[/tex], entonces tenemos que:

[tex]\sec 39^{\circ} = 1.287[/tex]

d) [tex]\tan 12^{\circ} = \frac{\sin 12^{\circ}}{\cos 12^{\circ}}[/tex]

Por tablas trigonométricas tenemos que [tex]\sin 12^{\circ} \approx 0.208[/tex] and [tex]\cos 12^{\circ} \approx 0.978[/tex], entonces tenemos que:

[tex]\tan 12^{\circ} \approx 0.213[/tex]

e) [tex]\csc 16^{\circ}24' = \csc 16.4^{\circ}[/tex]

[tex]\csc 16.4^{\circ} = \frac{1}{\sin 16.4^{\circ}}[/tex]

Por tablas trigonométricas tenemos que [tex]\sin 16^{\circ} \approx 0.276[/tex] y [tex]\sin 17^{\circ}\approx 0.292[/tex], mediante interpolación lineal tenemos que:

[tex]\csc 16.4^{\circ} \approx 3.542[/tex]

f) [tex]\sin 34.5^{\circ}[/tex]

Por tablas trigonométricas tenemos que [tex]\sin 34^{\circ} \approx 0.559[/tex] y [tex]\sin 35^{\circ} \approx 0.574[/tex], mediante interpolación lineal tenemos que:

[tex]\sin 34.5^{\circ}\approx 0.566[/tex]

Answer:

C = [tex]\frac{2.8}{7} + 0.75[/tex]

$1.15

Step-by-step explanation:

Here is the complete question :

Cookies are on sale! Today each cookie costs $0.75 less than normal price. Right now if you buy 7 of them it will only cost you $2.80!

write an equation to determine the normal price of each cookie (C). Find he normal price of each cookie.

the discounted price of one cookie = total sales price of 7 cookies / 7

$2.8 / 7 = $0.4

it was stated in the question that the sales price is  $0.75 less than normal price. Thus the normal price of the cookie = $0.4 + $0.75 = $1.15

the equation : [tex]\frac{2.8}{7} + 0.75[/tex]

Answer:

250

Step-by-step explanation:

32(7) + 26 = 224 + 26

Answer:

Step-by-step explanation:

Solve this system using elimination by addition and subtraction:

Multiplying the second equation by -2 yields the modified system

8x - 2y = -4

-8x + 2y = +4

Adding these together, we get 0 + 0 = 0  (This is always true.)

There are an infinite number of solutions.

Answer:

180 degrees

Step-by-step explanation:

because NJK adds up to 180 degrees and a circle is 360 degrees. Hope this helped :)

Answer and Step-by-step explanation:

When we take a look at the graph, we can see that at around 1 gallon, which would be halfway between 0 and 2, the line is underneath $5.

That means we can eliminate any number that is or above $5.

That leaves us with answer choices A and C.

Let's go to a point that is easily readable. Point (4, 15) is readable, and we can use this to find the price per gallon.

Divide 15 by 4. We get 3.75 as the result.

This means that the answer choice is:

C. The cost of gas is $3.75 per gallon.
