Answer:

n = -6

Step-by-step explanation:

n -12 = 3n

2n = -12

n = -6

Answer:

n=-6

Step-by-step explanation:

So first, you should subtract n from both sides to isolate the number -12. This will make the equation look like 2n=-12. Divide both sides by 2 because you want n to be by itself. This will give you the answer n=-6

Answer:

  B.  x = 2√11

Step-by-step explanation:

The square of the length of the diagonal is ...

  d² = 6² + 8² = 36 +64 = 100

Then the length of x is found from ...

  d² +x² = 12²

  x² = 144 -100 = 44 . . . . . subtract d²

  x = √44 . . . . . . take the square root

  x = 2√11

Answer:

5 and 100

8 and 160

9 and 180

12 and 240

Step-by-step explanation:

Since for every one sweatshirt there is $20 collected. Simply plug this in and do the multiplication and division.

5x20 = 100

8x20 = 160

180/20 = 9

12x20 = 240

Answer:

3, 5, 8, 9, 12

60, 100, 160, 180, 240

Step-by-step explanation: the only values that you have full information for is the first column

3, 60

to get from 3 to 60 you would multiply by 20, so for the next column multiply 5 by 20 to get 100

then 8, 160

for the fourth column you would just divide 180 by 20, 9

and finally for the last column you would multiply 12 by 20 to get

240

Answer:

the answer to that question is 152.5%

Step by Step Explanation:

(404 - 160)/|160| =

244/160 =

244 ÷ 160 =

244 ÷ 160 × 100/100 =

(244 × 100 ÷ 160)/100 =

(24,400 ÷ 160)/100 =

152.5/100 =

Answer:

8feet

Step-by-step explanation:

Given the equation that models the arch of a school expressed as;

[tex]$y=-0.5\left(x+4\right)\left(x-4\right)$[/tex]

If the x axis represents the ground;

At the ground level, x = 0

Substitute x = 0 into the equation to get y;

y = -0.5(0+4)(0-4)

y = -0.5(4)(-4)

y = -0.5 * -16

y = 8ft

Hence the y axis at the ground level is 8feet

Consider the given right triangle. We have to find the value of 'x'. So, the value of 'x' is 9.2 cm. Option 3 is the correct answer.

Step-by-step explanation:

Answer:

1 459.25 feet (1459 feet 3 inches)

Answer:

C = √185 or 13.6 units.

and cannot be simplified any further because it is irrational.

Step-by-step explanation:

Since the triangle has sides A = 4 units and B = 13 units. With C as its hypotenuse side, from Pythagoras' theorem C² = A² + B².

So, substituting A and B into the equation, we have

C² = 4² + 13²

C² = 16 + 169

C² = 185

taking square root of both sides, we have

√C² = √185

C = √185

C cannot be simplified any further because it is irrational. It is best expressed as √185 which is a surd. C could also be expressed as a decimal. So using your calculator and taking √185, C = √185 = 13.605 ≅ 13.6 units.

Answer: p=60

Step-by-step explanation:

Angles on a straight line always add up to 180 degrees.

So, because you have an angle on the straight line with the arrow going up, you have to do:

180-110=70

This will give you the angle inside of the triangle that is next to 110.

Then you would find the angle next to 130 (using the horizontal line) by using the same method so you would do:

180-130=50

This gives you the angle inside the triangle next to 130.

Then because a triangle always adds up to 180 you would add up the 2 angles you have figured out like this:

70+50=120

Then you would take the answer away from 180 like this:

180-120=60

So, p=60

Hope this helps :)

Answer:

Okay, so I checked on my calculator, and 5,6, and 7 are right

Step-by-step explanation:

Number 8 would be 45 degrees.  Both of the missing angles would be 45 degrees

Those two lines on either side of the triangle mean both of the angles are the same.

Option C

1.62 and -0.62

Step-by-step explanation:

v² - v - 1 = 0

From ax² + bx + c = 0

a = 1 b = -1 c = -1

Quadratic formula

x = -b +/- √b² - 4ac

--------------------------

2a

x = -(-1) +/- √-1² - 4 x 1 x -1

-----------------------------------

2(1)

x = 1 +/- √1 +4

-----------------

2

x = 1 +/- √5/2

x = 1 + √5/2 or x = 1 - √5/2

x = 1.618 or -0.618

Answer:

2 5/14 yards

Step-by-step explanation:

Area of the rectangular floor = Length * Width

Given

Area = 8 1/4 square yards

width = 3

1/2 yards

Required

Length

Length = Area/width

Length = (8 1/4)/(3 1/2)

Length = 33/4 ÷ 7/2

Length = 33/4 * 2/7

Length = 33/14

length = 2 5/14 yards

This gives the required length

Answer:

61.25

Step-by-step explanation:

The of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.

Volume of cone is the amount of quantity, which is obtained it in the 3 dimensional space.

The volume of the cone can be given as,

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

Here, (r) is the radius of the base of the cone and (h) is the height of the cone.

A cone-shaped party hat has a radius of r=3 inches and a height of h=6.5 inches. The amount of cubic units it occupies is equal to the volume of hat.

Thus, put the values in the above formula as,

[tex]V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=\dfrac{1}{3}\pi (3)^2(6.5)\\V=61.26\rm\; in^3[/tex]

Thus, the of cubic units which hat occupies having a radius of 3 inches and a height of 6.5 inches is 61.26 cubic inches.
