Answer:

n = - $\frac{3}{5q}$

Step-by-step explanation:

Given

2nq = 3 + 7nq ( subtract 7nq from both sides )

- 5nq = 3 ( divide both sides by the multiplier - 5q )

n = $\frac{3}{-5q}$ = - $\frac{3}{5q}$

Answer:

n= -3/q

Step-by-step explanation:

2nq-7nq=3

-5nq=3

n = -3/q

The diagram is a hat box that is designed with the shape of a regular octagon inside and a rectangle outside. Find the value of

nekit [7.7K]

In a regular octagon all the interior angles are of the same value.
sum of the interior angles in octagon = (n-2) *180°
n - number of sides, in this case, n = 8
interior angles sum = (8-2)*180° = 6*180° = 1080°
since there are 8 equal angles = 1080/8 = 135°
Angle x + one interior angle of the octagon = 180 ° (as its a straight line)
x + 135 = 180
x = 45°

PLS HELP ASAP GIVE BRAINLIEST TO PERSON WHO ANSWER CORRECTLY

Paladinen [302]

Answer:

B.) , ratio of 20:1
C.) , There are 11 costumers per tower and 11000 costumers in total

Step-by-step explanation:

Please mark brainliest...

multiply each value of the C. by 1,000 to get the # of C.s
divide the # of C.s / T.s
this gives you C.s per T.
Convert to ratio format
there is on average 15 to 20 C.s per T.

5250/273 = 14.075
6250/325 = 19.230
7250/377 = 19.230
9250/273 = 19.230

6250 = y

377 572

2. multiply both sides by 572

3. 572 . 6250 = y

377

4. divide known pair

572 x 19.230 = y

5. solve for y

6. y = 10999.56

7. divide y value by 1000

8. 10.99956

9. round to the nearest whole #

10. There are 11 costumers per tower and 11000 costumers in total

Find the value of each variable.

insens350 [35]

Step-by-step explanation:

11)

x= 5

${y}^{2} = 2 \times {5}^{2} \\ {y}^{2} = 50 \\ y = 5 \sqrt{2}$

12)

$\tan(30 ) = \frac{9}{y} \\ y = \frac{9}{ \tan(30) } = 9 \sqrt{3} \\ {x}^{2} = {9}^{2} + {(9 \sqrt{3} )}^{2} \\ {x}^{2} = 324 \\ x = 18$

13)

$\sin(60) = \frac{x}{22} \\ x = 11 \sqrt{3} \\ \cos(60) = \frac{y}{22} \\ y = 11$

14)

${16}^{2} = {x}^{2} + {y}^{2} \\ x = y \\ {16}^{2} = 2 {x}^{2} \\ x = 8 \sqrt{2} \\ y = 8 \sqrt{2}$

15)

$\tan(30) = \frac{x}{42} \\ x = 14 \sqrt{3} \\ \cos(30) = \frac{42}{y} \\ y = \frac{42}{ \cos(30) } \\ y = 28 \sqrt{3}$

16)

${(19 \sqrt{2}) }^{2} = {x}^{2} + {y}^{2} \\ x = y \\ 722 = 2 {x}^{2} \\ {x}^{2} = 361 \\ x = 19 \\ y = 19$

Question 19 makes no sense

gavmur [86]

Think: To write the equation of a line in slope-intercept form y=mx+b, you must have the slope (m) and the y-intercept (b).

g(0)= -6 tells us that the y-intercept is (0, -6). Thus, b= -6.

(0,-6) and (15,-9) are points on the line. Find the slope of the line. It is:
-9-(-6)
m = ------------- = -3/15 = -1/5
15-0

Thus, the equation of the line in question is y=(-1/5)x - 6.

Important that you understand that g(0)=-6 is also represented by (0,-6), and that -6 is the y-intercept.
