Answer:

62 miles

Step-by-step explanation:

The formula for average is given as

Sum of values / Number of values

Let x = miles on the last day

Hence

48 + 51 + 59 + x/4 = 55

Cross Multiply

= 158 + x = 220

x = 220 - 158

x = 62

Therefore, he needs to bike 62 miles on the last day so that his average (mean) is 55 miles per day.

Answer:

- 13[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying [tex]\sqrt{54}[/tex]

[tex]\sqrt{54}[/tex]

= [tex]\sqrt{9(6)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{6}[/tex]

= 3[tex]\sqrt{6}[/tex]

Then

2[tex]\sqrt{6}[/tex] - 5[tex]\sqrt{54}[/tex]

= 2[tex]\sqrt{6}[/tex] - 5 (3[tex]\sqrt{6}[/tex] )

= 2[tex]\sqrt{6}[/tex] - 15[tex]\sqrt{6}[/tex]

= - 13[tex]\sqrt{6}[/tex]

Answer:

Explicit formula: a(n)=3n-6

Recursive formula: a(n)=-3+(n-1)3 <--

Step-by-step explanation:

a(n)=3n-6 where a(1)=3(1)-6=-3 and d=3

Plug values into recursive formula:

a(n)=a1+(n-1)d

a(n)=-3+(n-1)3

Answer:

B y = -.001x +100

Step-by-step explanation:

(0,100) (2000,98)

98-100/ 2000-0 = -2/2000 = -1/1000

y-100 = -.001(x -0)

y= -.001x +100

Step-by-step explanation:

Answer:

When x = -2, y = 3

When x = -1, y = 0

When x = 0, y = -3

When x = 1, y = -6

Step-by-step explanation:

Given:

y = -3x - 3

Fill in the table using the following value for x

When x = -2

y = -3x - 3

y = -3(-2) - 3

y = 6 - 3

y = 3

When x = -2, y = 3

When x = -1

y = -3x - 3

y = -3(-1) - 3

y = 3 - 3

y = 0

When x = -1, y = 0

When x = 0

y = -3x - 3

y = -3(0) - 3

y = 0 - 3

y = -3

When x = 0, y = -3

When x = 1

y = -3x - 3

y = -3(1) - 3

y = -3 - 3

y = -6

When x = 1, y = -6

Answer:

4/5

Step-by-step explanation:

Given :-

We need to find the value of sin(β) in the given triangle . We know that the ratio of sine is ,

[tex]:\implies[/tex] sin(β) = p/h

[tex]:\implies[/tex] sin(β) = 4/5

Answer:

The angles have measurements 36, 72, 108, 144, and 180.

Step-by-step explanation:

Pentagon has 5 sides and 5 angles.

The amount of triangles formed by choosing one vertex and drawing from that vertex to every nonadjacent vertex is 3.

3(180)=540 which is the sum of the angles in a pentagon.

So since the ratio is 1:2:3:4:5, that means the angles are 1x,2x,3x,4x, and 5x.

We have the equation 1x+2x+3x+4x+5x=540 to solve.

15x=540

Divide 15 on both sides:

x=540/15

x=36

1x=36

2x=72

3x=108

4x=144

5x=180

The angles have measurements 36, 72, 108, 144, and 180.

The point that partitions segment AB in a 2: 1 ratio is point (5,19/3).

Suppose the point that partitions segment AB in a 2: 1 ratio is point (x,y)

The internal division formula for a line segment is given by:

[tex]x=\frac{m_1x_2+m_2x_1}{m_1+m_2}[/tex]

[tex]y=\frac{m_1y_2+m_2y_1}{m_1+m_2}[/tex]

Where (x₁,y₁) and (x₂,y₂) are endpoints of the line segment.

Coordinates of points A≡(1,3)

Coordinates of points B≡(7,8)

[tex]x=\frac{2*7+1*1}{1+2}[/tex]

[tex]x=5[/tex]

Similarly, [tex]y=\frac{19}{3}[/tex]

So (x,y)≡(5,19/3)

Hence, the point that partitions segment AB in a 2: 1 ratio is point (5,19/3).

Answer:

6.8

Step-by-step explanation:

8 * 6 = 48 (to reverse dividing by 6 to basically un-average the 6 numbers).

5 * 4 = 20 (to un-average these numbers as well).

48 + 20 = 68

68 / 10 = 6.8

Basically by doing this you are still adding all the numbers together & then dividing by 10 as if you added them all up at once & not in a group of 6 & a group of 4.

Hope this helped. :)

Given:

A square base pyramid with base length 6 cm and the slant height is 4 cm.

To find:

The lateral surface area of the given square pyramid.

Solution:

The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.

Area of a triangle is:

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

So, the area of one triangle or one side of the given pyramid is:

[tex]A_1=\dfrac{1}{2}\times 6\times 4[/tex]

[tex]A_1=\dfrac{24}{2}[/tex]

[tex]A_1=12[/tex]

Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.

[tex]LA=4A_1[/tex]

[tex]LA=4(12)[/tex]

[tex]LA=48[/tex]

Therefore, the lateral surface area of the given square pyramid is 48 cm².

Answer: 48
