what is the domain of f(x) = (x+3)/(x^2-64)

Answer:

C

Step-by-step explanation:

Answer:

B:81

C:99

D:81

Step-by-step explanation:

In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.

[tex]\\ \sf\longmapsto <A=<C=99°[/tex]

sum of corresponding angles is 180°

[tex]\\ \sf\longmapsto <A+<B=180[/tex]

[tex]\\ \sf\longmapsto 99+<B=180[/tex]

[tex]\\ \sf\longmapsto <B=180-99[/tex]

[tex]\\ \sf\longmapsto <B=81[/tex]

[tex]\\ \sf\longmapsto <B=<D=81°[/tex]

So

[tex]2 \ \frac{1}{4} = \frac{9}{4} [/tex]

So,

total sugar he has to use in making full recipe is

[tex]2 \ \frac{1}{4} [/tex]

But he is only making

[tex] \frac{2}{3} [/tex]

of recipe

So we have to 'minus' this.

So as u see in the above picture"sry for bad handwriting'' when we subtract we get an improper fraction and then we convert it to mixed fraction...

So the answer is

[tex]1 \ \frac{7}{12 \:} of \: sugar[/tex]

hope it helps:-)

Answer:

16.5

Step-by-step explanation:

Given data to us is ,

Arrange it in ascending order .

= 12 , 14 , 15 , 16 , 17 , 20 , 20 , 22

The middle most observation will be median in case n is odd and average of middlemost observations if n is even , that is n = 8 .

=> Middlemost observations = 16 , 17

=> Mean = 16 + 17 /2 = 33/2 = 16.5

Answer:

13/18

Step-by-step explanation:

Answer:

Solve all the equations.

2+n = 6

n = 4

n + 6 = 12

n = 6

4 × n = 24

n = 6

n × 3 = 2

n = 2/3

The bold equations are the answers.

Answer:

c. 273 cars

Step-by-step explanation:

First you need to find what 16% of 325 is

325x.16=52

because the number sold dropped by 16% you will subtract 52 from 325

325-52=273

you can also calculate the answer by subtracting 100% by 16%

100%-16%=84%

now you can calculate 84% of 325

325x.84=273

Answer:

THE ANGLES

Step-by-step explanation:

Answer:

s = 6 feet

Step-by-step explanation:

Given that,

The volume of the cube, V = 216 feet³

We need to find the side length for the cubical box. We know that the volume of the cube is given by :

[tex]V=s^3[/tex], s is the side length of the box.

So,

[tex]s={V}^{1/3}\\\\s={216}^{1/3}\\\\s=6\ feet[/tex]

So, the side length for the cubical box is equal to 6 feet.

Answer:

x - 2 and x + 5

Step-by-step explanation:

Given Area Of rectangle

= x² + 3x - 10

= x² + ( 5 - 2)x - 10

=x² + 5x - 2x - 10

= x ( x + 5 ) - 2 ( x + 5 )

= ( x + 5 ) ( x - 2 )

Answer:

I think the answer is A, $5.60

Step-by-step explanation:

9.80 x 9= 88.20

88.20 - 37.80 = 50.40

5.60 x 9 = 50.40

The average amount paid for the books is $12.60

Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:

= $9.80 × 9

= $88.20

Since she bought 4 new books and had $37.80 left over, the cost of the books will be

= $88.20 - $37.80

= $50.40

Since she bought 4 books, the average amount paid for the books will be:

= $50.40/4

= $12.60

Therefore, the correct option is D

Answer:

You'd have 288 hours for 60 mins.

Step-by-step explanation:

if 1hr=50 mins for 240 hours

then 50mins =240hours

thus, 60 mins =x hours

Cross multiply

then you have 50mins × x hours=60 mins ×240 hours

therefore,50mins×x/50 mins=240 hours×60/50mins

then,x on the L.H.S =24×12 after division on R.H.S

so, x=288 hours

therefore,for 60 mins you'd have 288 hours of English

Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.

Height = sqrt(8^2 - 5^2)

Height = sqrt(64 - 25)

Height = sqrt(39)

Height = 6.245 ( Round the answer as needed).

Answer:

6.2

Step-by-step explanation:

We can use the Pythagorean Theorem to find h.

The equation for the Pythagorean Theorem is a^2+b^2=c^2

We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.

We have:

a^2+b^2=c^2

5^2+h^2=8^2

25+h^2=64

h^2=39

h= square root of 39

h = 6.244
