Answer:

5√8, √170, 5/8, 0.62

Step-by-step explanation:

5√8 = 14.1

√170 = 13.03

5/8 = 0.625

0.62 = 0.62

Answer:

5sqrt(8), sqrt(170), 5/8, 0.62

Step-by-step explanation:

Solve any equations and put them in decimal form to make it easier to list them from biggest to smallest.

Ex: sqrt(170) = 13.04

5sqrt(8) = 14.14

5/8 = .625

Answer:

62 Pounds

Step-by-step explanation:

then gains 9 pounds

53 + 9 = 62

Therefore Sam weighs 62 pounds

Answer:

x=6

y=2

Step-by-step explanation:

-x+3y=0 (1)

x+3y=12 (2)

(1)+(2)<=> 6y=12

Answer:

53

Step-by-step explanation:

72 = x + 3x - 4

72 = 4x - 4

72 + 4 = 4x - 4 + 4

76 = 4x

76/4 = 4x/4

x = 19

3(19) - 4 = 53

Hope this helps!

Answer:

66 people

Step-by-step explanation:

There are 264 in 4 subway cars, we can use proportions to solve this question so 264 people/4 cars = 4 cars/4 cars which equals 66 people = 1 car

The length of the wire AC is 61 meters.

Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.

We can find the length of wire AC using Pythagoras theorem:

AC² = 60² + (66 - 55)²

AC² = 60² + 11²

AC² = 3721

AC = 61 meter

The length of the wire AC is 61 meters.

Answer:

A  8º

B  76º

C  74º

D  128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

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

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) =  24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

Answer:

a4 = 128

a5 = -512

Step-by-step explanation:

a1= -2

q= (-1)^(n+1) × 4

a4 = a1q³ = (-2) (-4)³ = -2 × -64 = +128

a5 = a1q⁴ = (-2) (-4)⁴ = -2 × 256 = -512

The distribution is not a standard normal distribution.

We know that the variable (X) usually obeys and follows a standard normal distribution provided that the summation of (X) is zero and the variance of the random variable V(X) = 1.

Mathematically:

E(X) = 0 and V(X) = 1

Given that;

As such, the distribution is not a standard normal distribution.

Therefore, we can conclude that the distribution is not a standard normal distribution.

Answer:

Step-by-step explanation:

-3-5=-8

-11-(-3)=-11+3=-8

-19-(-11)=-19+11=-8

it is an A.P. and c.d.=-8

so nth term is

an=a1+(n-1)d

an=5-(n-1)(-8)

an=5+8n-8

an=8n-3

Observing the given matrix we can say that:

1) The value is 4.

2) The value is 2.

So analyzing the different paths that can connect city 1 to city 3: The value is 4. It represents the number of one-stop routes between City 1 and City 3 that pass through City 2.

For the second statement we will have the value is 2. It is the number of direct routes from  City 2 to City 5.

Answer:

32

Step-by-step explanation:

work backwards, 19-11=8 then x 4 makes 32.

Answer:

32

Step-by-step explanation:

Let the number be 'x'

[tex]\dfrac{x}{4}+11=19[/tex]

Subtract 11 from both sides

[tex]\dfrac{x}{4}=19 - 11\\\\\dfrac{x}{4}=8\\[/tex]

Multiply both sides by 4

x = 8*4

x = 32

Answer:

15 is a composite number. 15 = 1 x 15 or 3 x 5. Factors of 15: 1, 3, 5, 15. Prime factorization: 15 = 3 x 5

Step-by-step explanation:

Answer:

15= 3 x 5

Step-by-step explanation:

                            15

                        /      /

                      5   x    3

3 and 5 both multiply together to make 15

1: Angles 2 & 6 + angles 3 & 7

     - Angles that are on the inside of the parallel lines and on opposite sides of the transversal  

2: Angle 1

     - Angles in the same position but the other line

3: Alternate exterior angles

     - Angles that are on the outside of the parallel lines and opposite sides of the transversal

4: Same side interior angles

     - They are on the same side of the transversal and inside the parallel lines

5: Angle 2

     - It is supplementary and on the inside of the parallel lines

6: Angle 4

     - It is supplementary and on the outside of the parallel lines

7: 146°

     - They are corresponding angles, so they are the same measurement  

8: 128°

     - They are supplementary angles, so 180 - 52 = 128

For 9 & 10:

     - They are supplementary, so adding them together will result in 180 degrees

     - (8x + 63) + (5x) = 180 -> 8x + 5x + 63 = 180 -> 13x = 117 -> x = 9

     - Now we will plug it in to find the individual measurements:

9: 135°

     - 8x + 63 -> 8(9) + 63 -> 72 + 63 = 135

10: 45°

     - 5x -> 5 (9) = 45

                         I hope this helps, have a nice day! :D

Answer:

the equation of the height= tan 40 = y/ 120

Step-by-step explanation:

since the distance between the boat and the light house is 120°

: using trigonometry

tan theta = opp/adj

therefore it is y/120°

Answer: Slope (M) = 7.5

Y-intercept (B) = 0

Step-by-step explanation:

For the slope, the first step is to find your "pretty points" (spots on the slope that hit the corner perfectly, like (0, 0) or (2, 15).

Now, make a triangle with the two points. Count the amount of squares on both. This will give you 3 and 4, but when taking the units into consideration, 15 and 2. The last step is to divide 15 and 2 which gives you 7.5. I would recommend writing both 15/2 and 7.5 but it's up to you.

The Y-intercept is just the spot where the Y is 0, or where the line touches the Y-axis. This is at the origin, where both X and Y are 0, so your Y-intercept is 0.

I'm kinda bad at explaining things in words, so sorry if this makes no sense, but I hope this helps!

Step-by-step explanation:

these are all isoceles triangles (2 sides are equal). that also means that the 2 angles at the end of the equal sides are equal.

so, the angle at F and H are both 65°.

the angle at J = 2×65 = 130°.

the angle at G = 2×(180 - 65 - 65) = 2×50 = 100°.

remember, the sum of all angles in a triangle is always 180°.

so many ways now to get y.

let's use the triangle GH and crossing point of diagonals (there is a right angle).

y = 180 - G/2 - 90 = 180 - 50 - 90 = 40°

Answer:

y = - [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (3, - 2) ← 2 points on the line

m = [tex]\frac{-2-2}{3-0}[/tex] = [tex]\frac{-4}{3}[/tex] = - [tex]\frac{4}{3}[/tex]

The line crosses the y- axis at (0, 2 ) ⇒ c = 2

y = - [tex]\frac{4}{3}[/tex] x + 2 ← equation of line
