Find the value of x?
x = ___ degrees

Answer:

No

Step-by-step explanation:

The sum of all angles in a triangle is 180°. Because 60 + 60 + 63 = 183 ≠ 180, this is not a triangle.

The sum of all angles in triangle is equeal to 180°

We need to check sum of 60, 60 and 63.

60+60+63=183

183≠180

There is no such triangle

Answer:

6782.4 m^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

where r is the radius and h is the height

V = 3.14 * 12^2 * 15

  = 6782.4 m^3

Answer:

Its A  x - 55 = 39

Step-by-step explanation:

x - 55 = 39

x = 39 + 55

x = 94

This is correct as they sold 39 and kept 55

This means they had 94 to begin with.

I hope this helps ^_^

Answer:

right angle:-a Pythagorean theorem only works if the triangle is a right angle.

leg:- the two legs of a triangle are needed to complete the equation a²+b²=c²

hypotenuse:- too is needed to complete the equation too.

square root:- is used to simplify the equation at the end.

it was simplified by putting 169=x² in a square root.

When two lines intersect at 90° degrees angle, the lines are perpendicular to each other. Two perpendicular lines, their slope will give a product of -1

i.e. if the first's line slope is 5, then the second line's will be -1 ÷ 5 = -¹/₅

To find the slope of a line, we divide the vertical distance by the horizontal distance. 

We'll use the trial and error method to find the right pairing

Let's start with A(3, 3) and B(12, 6)

Vertical distance = 

Horizontal distance = 

The slope AB = ³/₉ = ¹/₃

We want BC to have a slope -1 ÷ ¹/₃ = -3

Try C(16, -6); check the slope with B(12, 6)

Vertical distance = 

Horizontal distance = 

Slope of BC = -12 ÷ 4 = -3

The slope BC = -3 is the value we want so, tile 1 pair with tile 4

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

Let's do A(-10, 5) and B(12, 16)

Vertical distance = 16 - 5 = 11

Horizontal distance = 12 - -10 = 22

Slope AB = ¹¹/₂₂ = ¹/₂

The perpendicular slope would be -1 ÷ ¹/₂ = -2

Try C(18, 4)  with B(12, 16)

Vertical distance = 16 - 4 = 12

Horizontal distance = 12 - 18 = -6

Slope BC = ¹²/₋₆ = -2

Slope BC and slope AB perpendicular, so tile 3 matches with tile 6

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

Let's try A(12, -14) and B(-16, 21)

Vertical distance = 21 - -14 = 35

Horizontal distance = -16 - 12 = -28

The slope AB = ³⁵/-₂₈ = ⁵/₋₄

We need the perpendicular slope to be -1 ÷ -⁵/₄ = ⁴/₅

Try C(-11, 25)

Vertical distance with B = 25 - 21 = 4

Horizontal distance with B = -11 - -16 = 5

The slope = ⁴/₅

Tile 7 matches tile 8

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

Take A(-12, -19) and B(20, 45)

Vertical distance = 45 - -19 = 64

Horizontal distance = 20 - -12 = 32

Slope AB = ⁶⁴/₃₂ = 2

We need the perpendicular slope to be -1 ÷ 2 = -¹/₂

We have C(6, 52) and checking the slope with B(20, 45)

Vertical distance = 45 - 52 = -7

Horizontal distance = 20 - 6 = 14

The slope is ⁻⁷/₁₄ = -¹/₂

Tile 9 pairs with tile 2

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

Conclusion

Tile 1 ⇒ Tile 4

Tile 3 ⇒ Tile 6

Tile 7 ⇒ Tile 8

Tile 9 ⇒ Tile 2

Tile 5 and Tile 10 do not have pairs

Answer:

[tex]x = 2[/tex]

Step-by-step explanation:

[tex]2x + 6 = 10 \\ 2x = 10 - 6 \\ 2x = 4 \\ \frac{2x}{2} = \frac{4}{2} \\ x = 2[/tex]

Answer:

x=2

Step-by-step explanation:

2x+6 = 10

Subtract 6 from each side

2x+6-6=10-6

2x= 4

Divide by 2

2x/2 = 4/2

x = 2

Answer:

D and E are the correct answers

Step-by-step explanation:

A is false: The difference between the greatest and least weights is NOT 1/2.

B is false: 2/9 of the packages weigh 5/8 pounds...not 1/4.

C is false: You can clearly see there were more than 12 packages purchased.

D is true: 3/4 = 6/8 and there is 1 package that weighs 6/8 pounds 1 x 3=3 and there is a total of 3 packages that weigh 1 1/8 pounds.

E is true: 1/2=4/8 and the smallest amount is 5/8 pounds which is over 1/2 pound.

Answer:

The answer is "8".

Step-by-step explanation:

Let the number are a, b, c then value is as follows:

a= 3

b= 5

c= 7

The addition of equation ⇒ a+b+c =15....................(i)

multiply by the value ⇒ 3a + 5b + 7c = 75 ...............(ii)

let b= 15-a-c which  subtract from equation (ii)  

equation:

 ⇒ 3a + 5b + 7c = 75

⇒ 3a + 5(15-a-c) + 7c = 75

⇒ 3a +75-5a-5c+7c = 75

⇒ 3a -5a-5c+7c  = 75-75

⇒ -2a + 2c  = 0

⇒ 2(c-a)  = 0

⇒ (c-a)  = 0

⇒ c=a

if we put value in between 0 to 7 from it satisfies the two equations, with c=a and b = 15 - a - c. So, the correct answer is 8.

Answer:

Density: 1.6g/cm^3

Step-by-step explanation:

Density = mass/volume

Mass: 12.9g

Volume: 8cm^3

12.9/8 = 1.6125

Rounded to tenths place.

1.6 grams/cm^3

Answer:

1.61 g/cm³

Step-by-step explanation:

Density is measured as the mass divided by the volume:

d = m / v, where d is the density, m is the mass, and v is the volume

Here, our mass is 12.9 g and our volume is 8 cm cubed, so plug these in:

d = m / c

d = 12.9 g / 8 cm³

d = 1.6125 ≈ 1.61 g/cm³

The density is 1.61 g/cm³.

Answer:

y = 0.4x

Step-by-step explanation:

The graph shows that the relation is linear, so we can model this relation with a linear equation:

y = ax + b

To find the value of the parameters, we should get two points from the line and use their coordinates in the equation.

From point (0,0), we have:

0 = a*0 + b

b = 0

From point (2,5), we have:

2 = 5a + b

a = 2/5 = 0.4

So the equation we want is:

y = 0.4x

Answer: 8

Step-by-step explanation: Speed is distance/time

18/3 = 6 miles per hour running

18/2 = 9 miles per hour biking

3 hour bike = 27 miles

1.50 hour run (0.50 because 30 minutes is half of an hour) = 9 miles

27 + 9/3 + 1.50 = 36/4.5 or 8

Answer:

258 increased by 43% = 368.94

368.94 - 258 = 110.94 as absolute change

Step-by-step explanation:

258 + Percentage increase =

258 + (43% × 258) =

258 + 43% × 258 =

(1 + 43%) × 258 =

(100% + 43%) × 258 =

143% × 258 =

143 ÷ 100 × 258 =

143 × 258 ÷ 100 =

36,894 ÷ 100 =

368.94; with 110.94 as absolute change.

The required simplified value is given as £368.94.

As given in the question, to determine an increase £258 by 43%.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the required value be x,
According to the question,
x = 258 [1.43]
x = 368.94

Answer:

1.  3

2. A

Step-by-step explanation:

1. (-3+3)^2 + (2 + 1)^2 - r^2 = 0

0 + 9 - r^2 = 0

r^2 = 9

r = 3

2. 2x^2 + 4x + 2y^2 + 12y = - 6

Divide by 2.

(x^2 + 2x) + (y + 6y) = -3

Remember how to complete the square..

(b/2)^2

So...

(2/2) ^ 2 = 1

(6/2) ^ 2 = 9

(x^2 + 2x + 1) + (y^2 + 6y + 9) = -3 + 1 + 9 <--- You must remember to add whatever you add on the left to the right!

Now.. rewrite in standard form..  

(x+1)^2 + (y+3)^2 = 7

Careful!! the circle equation is written as

(x - h)^2 + (y - h)^2 = r^2

Meaning that the radius is square root of 7. At center (-1, -3)

Answer:you get two answers. y+6=-7/4(x+5) or y-1=-7/4(x+5)

Step-by-step explanation:

By the way the 7/4 is negative if you could not tell. You get this answer by finding the slope which is 1- -6/-5- -1 and get -7/4. Then you plug it into the formula y-y1=slope(x-x1). When you plug it in you should get that answer.

The equation of the line that passes through the point (-1, -6) and (-5, 1) is

y = (-7/4)x - 32/4

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is y = mx + c

Now,

(-1, -6) and (-5, 1)

Slope = m

m = (1 + 6) / (-5 + 1)

m = 7/-4

m = -7/4

Now,

(-1, -6) = (x, y)

-6 = (-7/4) x -1 + c

-6 = 7/4 + c

c = -6 - 7/4

c = (-24 - 7) / 4

c = -32/4

The equation of the line is y = (-7/4)x - 32/4

Thus,

The equation of the line is

y = (-7/4)x - 32/4

The congruence statement tells you that both angle B and angle E are equal, since the triangles are identical!

Step-by-step explanation:

We want to set the equations equal to each other.

2x+31=7x-24

We need to isolate our variable, which is X.

1. Add 24 to both sides.

New Equation: 2x+55=7x

2. Subtract 2x from both sides.

New Equation: 55=5x

3. Divide by 5 from both sides so X is alone!

New Equation: x=11
