Noah went shopping for a new camera. The listed price of the camera was $39, but the price with tax came to $40.56. Find the percent sales tax.

Answer:

1232 m^2.

Step-by-step explanation:

The net consists of 2 triangles and 3 rectangles.

Area of each triangle = 1/2 * 24*7 .

Area of 1 rectangle =  25 * 19.

The other 2 have areas 24*19 and 7 * 19.

Therefore the surface area of the prism

=  2 * 1/2 * 24 * 7 + 25*19 + 24*19 + 7*19

= 1232 m^2.

Answer:

in one litre there are 1000 milliliters

in 2.3 litres there are

2.3 × 1000 milli litres

= 2300 ml

The answer is 2 300 you just have to multiply by 1000

The correct answers to the given graph/number line:  " x > -6 " ;

are: Answer choices:  [A]: ​" 3(4 − x) < 30​ " ;
                             and:   [B]: " [tex]\frac{2}{3}[/tex] x + 9 > 5 " .
______________

Step-by-step explanation:
______________

Note:  The "given graph" is a "number line" that represents:
 " x > - 6 " .  

The "negative 6"; that is: "-6" is "circled"; which means "does not equal: ("-6");  there is a line, or geometrically speaking, a "ray" ; that continues to the side going forward to all value greater the "-6" .

_____

The question asks:
What inequalities describe the given {graph—in our case, number line.}.

So, there are 4 (four) answer choices.
We are to determine which Answer choice(s) are equal to:
      " x > - 6 " .
_____

Choice [A]:  " 3(4 − x) < 30 " ;
To simplify:
First, let us divide each side of this 'inequality; by "3":
       " [3(4 − x)] / 3 < [30/3] " to get:  " 4 − x  < 10 " ;
_____
We can multiply each side of this inequality by "-1" ;
 " -1(4 − x) < 10(-1) " ;

Note:  - 1(x − y) = y − x ;

and when each side of an Inequality, specifically, is multiplied or divided by a 'negative number'; we change the 'direction' of the inequality ;

So we simplify our inequality:
" x − 4 > -10 " ;  Add "4" to both sides of this inequality:

" x − 4 + 4 > -10 + 4 " ;  to get:  " x > -6 " ;  which is a correct answer.
_____
Choice: [B]:  " [tex]\frac{2}{3}[/tex] x + 9 > 5 " ;  To simplify:
Subtract "9" from each side:
  " [tex]\frac{2}{3}[/tex] x + 9 − 9 > 5 − 9 " ; to get:  " [tex]\frac{2}{3}[/tex] x > -4 ";  
Now, multiply the entire inequality by "3";
⇒  3*[[tex]\frac{2}{3}[/tex] x] > 3*(-4) ";  
to get:  " 2x > -12 ";  Now, divide Each side by "2" :
 " 2x /2 > -12 / 2 ";  to get:  " x > -6 " ; which is a correct answer!
_____
Choice [C]:  " -2(9 − x) < -6 " ; To simplify: Divide each side by "-2" ;

→ " [-2(9 − x)] /-2] < -6/-2 " ;
Note: When multiplying and dividing both sides of an 'inequality' by a 'negative number; the "sign/direction" of the inequality changes.

 → to get:  " 9 − x > 3 "; Now, multiply  each side by "(-1)";
→ " -1(9 − x) > (3*-1); Note, we are multiplying by a negative number, so we shall reverse the direction/sign of the inequality.  
Also: Note:  " -(x − y) = y − x) " ;  
→  So, we can simplify:
    " x − 9 < -3 " ;
Now, add "9" to each side:  
" x − 9 + 9 < -3 + 9 "; to get:  " x < -6 " ; which is not a correct answer.
_____
Choice: [D]: " 2x − 5 > 7 ";  Add "5" to each side of the inequality:
" 2x − 5 + 5 > 7 + 5 " ;  to get:  
   2x > 12 ;  Now divide each side of the inequality by "2" ;
       to isolate "x" on one side of the equation; & to solve for "x" ;
   2x / 2 > 12/2 ;  
   to get:  "x > 6 " ; which is not a correct answer.
______________
The correct answers to the given graph/number line:  " x > -6 " ;

are: Answer choices:  [A]: ​" 3(4 − x) < 30​ " ;
                             and:  [B]: " [tex]\frac{2}{3}[/tex] x + 9 > 5 " .

Answer:

jesse's mistake is in Step 1

Step-by-step explanation:

She had to subtract 9 from 11, which would have got her 2, for the part after the equal sign. However, she put 3, and 11-9 is not 3, so she is wrong.

Answer:

∠X = 48°

∠Y = 96°

∠Z = 36°

Step-by-step explanation:

   All angles of a triangle are equal to 180.

(3.2n) + (6.4n) + (2.4n) = 180

12n = 180

n = 15

   Now, we will solve for each angle.

∠X = 48°

3.2n

3.2(15)

48°

∠Y = 96°

6.4n

6.4(15)

96°

∠Z = 36°

2.4n

2.4(15)

36°

Answer:

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it. It is applicable to all types of triangles, whether it is scalene, isosceles or equilateral. To be noted, the base and height of the triangle are perpendicular to each other. The unit of area is measured in square units (m2, cm2).

Answer: The surface area is 21,274.4 square feet.

Step-by-step explanation:

The total surface area is 4 (0.5bh). Although you would multiply it by 4 because there 4 triangular faces, b is the base & h is the height. It’d change to A = 4(0.5) (116 ft) (91.7 ft) so your answer ends up as A = 21274.4 square feet.

Answer:

GCF = 44

2 Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

4(4/16x+4/12y)

3 Simplify each term in parentheses.

Answer:

9

Step-by-step explanation:

9/1 x 1/2 = 9/2

Answer:

see below

Step-by-step explanation:

9/2= ?x1/2

As 9/2 is on the other side of the equal sign and you want to combine like terms, you divide 9/2 by 1/2

9/2 x 2/1

(Flip the second term)

Cancel out the 2's

9/1 x 1/1

This equals 9

9/2= 9 x 1/2
