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.

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:

It will take 7 hours for car B to catch up to Car A.

Step-by-step explanation:

So if you write the the two equations out:

[tex]Car A=70x\\Car B= 90x-140[/tex]

You'll want to assume that x is how many hours and y is how many km.

The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.

If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.

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:

69.84%

Step-by-step explanation:

percentage increase

[tex]\frac{107-63}{63} \times 100\\=\frac{44}{63} \times 100\\=\frac{4400}{63} \\=69.84/%[/tex]

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

The percentage increase in the height of the tree is 69.84%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Height of the tree = 63 inches.

Height after several years = 107 inches.

Now,

The percentage increase in the height of the tree.

= (107 - 63)/63 x 100

= 44/63 x 100

= 69.84%

Thus,

The percentage increase in the height of the tree is 69.84%.

Answer:

1. (3, 5)

2. (1/2, 4)

Step-by-step explanation:

To find the coordinates of the midpoint of a segment, find the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.

1. (1, 2) and (5, 8)

x-coordinate of midpoint = (1 + 5)/2 = 6/2 = 3

y-coordinate of midpoint = (2 + 8)/2 = 10/2 = 5

Midpoint: (3, 5)

2. (0, 1) and (1, 7)

x-coordinate of midpoint = (0 + 1)/2 = 1/2

Answer:

35 to 44 is the error interval

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:

B

Step-by-step explanation:

29/37=0.783 783 783 8....

so it is just repeating

so the answer is b

(sorry about your computer :I)

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:

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

Answer:

Ok so first you would have to turn them into improper fractions which is

3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]

So now that you have made them both improper fractions you have to find common denominators.

To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex]. Then mutiply both numbers in [tex]\frac{7}{2}[/tex] by 5 to get a common denominator.

[tex]\frac{35}{10}[/tex]

[tex]\frac{35}{10} -[/tex] [tex]\frac{44}{10}[/tex] =35 - 44 = -9 so your answer is [tex]-\frac{9}{10}[/tex]

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:

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)
