Answer:

50.24

Step-by-step explanation:

Area = pi*r^2

r = diameter/2

r = 4

Area = pi*4^2

Area = 3.14*16

Area = 50.24

Answer:

Step-by-step explanation:

The area A of a circle of radius r is A = πr², where π is often approximated by 3.14.

Here, with the circle diameter being 8, we figure the radius to be half that, or 4.

Then the area of this circle is A = (3.14)(4 in)², or

                                                 A  =  50.24 in²

Answer:

72

Step-by-step explanation:

Answer:

30 in

Step-by-step explanation:

See attached image.

The length of AB is 17 (radius).  The length of AC is 8 (given info).

AC splits segment BD in half, so point C is the midpoint of segment BD.

AC is perpendicular to the chord, so triangle ABC is a right triangle.  You now have a right triangle with a leg of length 8 and hypotenuse of lenght 17.

The Pythagorean Theorem:  (leg)^2 + (leg)^2 = (hypotenuse)^2.

[tex]8^2+(BC)^2=17^2\\\\64+(BC)^2=289\\\\(BC)^2=225\\\\BC=\sqrt{225}=15[/tex]

That's half the length of the chord, so double that to get 30 inches for the full length of the chord BD.

Answer:

Prob (Arrive before 7.30) =  14 / 25 ; Prob (Arrive after 7.30) = 11 / 25

Step-by-step explanation:

Prob (Arrive before 7.30) = No. of days before 7.30 arrival / Total work days

= 28 / 50  = 14 / 25

Prob (Arrive after 7.30) = No. of days after 7.30 arrival / Total work days

= (50 - 28) / 50 = 22 / 50 = 11 / 25

or , 1 - Prob (Arrive before 7.30) = 1 - 14/25 = (25 - 11) / 25 = 11/ 25

Answer:

1/3 is not greater than 2/5

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

The n th term of a geometric sequence is

= a

where a is the first term and r the common ratio

Both a and r have to be found

Given a₃ = - 2, then

ar² = - 2 → (1)

Given a₇ = - 32, then

a = - 32 → (2)

Divide (2) by (1)

= , that is

= 16 ( take the fourth root of both sides )

r = 2 ← common ratio

Substitute r = 2 into (1)

a × 2² = - 2, that is

4a = - 2 ( divide both sides by 4 )

a = -  ← first term

Hence

= -  ← explicit formula

and

= -  ×  = - 0.5 × 512 = - 256

Step-by-step explanation:

Answer:

8 x 10 = 80

80 divided by 2 = 40

6 x 8 = 48

48 divided by 2 = 24

40 + 24 = 64 in2 is your answer.

Answer:

See Explanation

Step-by-step explanation:

Given

Luanne

[tex]Salt = 3\ cups[/tex]

[tex]Gallon = 1[/tex]

Fiona

[tex]Salt = 2\ cups[/tex]

[tex]Gallon = 3[/tex]

The question is incomplete, as the options are not given.

However, possible comparison that can be made are

(a) The unit amount of salt

(b) Whose solution is more concentrated with salt

(a) The unit amount of salt

To do this, we divide the amount of salt by the number of gallons.

[tex]Unit = \frac{Salt}{Gallon}[/tex]

For Luanne

[tex]Unit = \frac{3}{1}[/tex]

[tex]Unit = 3 cups/gallon[/tex]

For Fiona

[tex]Unit = \frac{2}{3}[/tex]

[tex]Unit = 0.67cups/gallon[/tex]

(b) Whose solution is more concentrated with salt

By comparing the result in (a)

We have:

[tex]Unit = 3 cups/gallon[/tex] --- Luanne

[tex]Unit = 0.67cups/gallon[/tex] --- Fiona

Luanne unit amount implies that there are 3 cups in every gallon of water;

Fiona unit amount implies that there are 0.67 cups in every gallon of water;

[tex]3 >0.67[/tex]

Hence, Luanne solution is more concentrated with salt

Answer:

42 ft

Step-by-step explanation:

body = x

tail = 7x

x + 7x = 48

8x = 48

Divide both sides by 8

x = 6

Tail

7x = 7(6)

7x = 42

Answer:

her mother drives 142 miles more than her brother.

Step-by-step explanation:

227 + 337 = 564 miles in total driven

¼ of 564 miles = 136 miles (what her brother drives of the 564 miles)

564 - 136 = 428 left

her mother drives 428-150 miles from Wednesday = 278

278-136=142

Answer:

[tex]390ft^2\\[/tex]

Step-by-step explanation:

Ok so we have 2 (congruent) triangles and 3 rectangles.

Your main approach to this problem should be to find the area of each of the faces and adding them up to get to your final answer. Your question makes a point of including the correct unit in your answer. Since this is surface area, the unit would be [tex]ft^2[/tex]

Now let's start:

First, I am going to start with finding the area of the rectangles.

[tex]12\cdot11=132\\13\cdot11=143\\5\cdot11=55\\\\55+143+132=330[/tex]

Alright, next lets move on to the triangles.

They are both the same, if you notice. So find one and double it.

[tex]12\cdot5=60\\\frac{60}{2}=30\\30\cdot2=60[/tex]

now lets add em all

330+60

= 390 and thats your final answer, dont forget to include the unit, ft^2

Answer:

9.9cm

Step-by-step explanation:

If side h cm is opposite of 51° and side 8cm is adjacent to 51°, use the tangent function to calculate the opposite side h cm:

tan(51°)=opposite/adjacent=h/8

tan(51°)=h/8

8tan(51°)=h

9.879177252=h

9.9=h

Therefore, the value of h is 9.9cm

(a) y = [tex]\frac{-1}{2}[/tex]x -  [tex]\frac{3}{2}[/tex]

(b) y = 2x + 3

(a) The equation of a line given by points M(x₁, y₁) and N(x₂, y₂) is given by:

y - y₁ = m(x - x₁)            -------------------(i)

Where;

m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = slope or gradient of the line  ---------------(ii)

Given points on the triangle are:

A(2,5)

B(1,-2)

C(-5,1)

To find the equation of line BC, we use the formulas in equations (i) and (ii) where the points of the line are B(1,-2) and C(-5,1) and;

x₁ = 1

y₁ = -2

x₂ = -5

y₂ = 1

==> First get the gradient using equation (ii) as follows;

m = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex] = [tex]\frac{1 - (-2)}{-5 -1}[/tex]

m =   [tex]\frac{3}{-6}[/tex]

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

==> Now, use equation (i) to find the equation of the line as follows;

y - (-2) = [tex]\frac{-1}{2}[/tex](x - 1)

y + 2 = [tex]\frac{-1}{2}[/tex](x - 1)

Multiply both sides by 2

2(y+2) = -1 ( x - 1 )

2y + 4 = -x + 1

2y = -x + 1 - 4

2y = - x - 3

y =  [tex]\frac{-1}{2}[/tex]x -  [tex]\frac{3}{2}[/tex]

Therefore, the equation of the line is y = [tex]\frac{-1}{2}[/tex]x -  [tex]\frac{3}{2}[/tex]

(b) To find the perpendicular line from A to BC, note that

i. two lines are perpendicular if they meet at 90°

ii. the general equation of a line could also be written as y = mx + c where m is the slope and c is the intercept.

iii. when one line has a slope of m, then a perpendicular line to that line will have a slope of [tex]\frac{-1}{m}[/tex]

The equation of line BC is y = [tex]\frac{-1}{2}[/tex]x -  [tex]\frac{3}{2}[/tex].

This means that BC has a slope of [tex]\frac{-1}{2}[/tex]

A perpendicular line from A to BC will have a slope of 2.

Now to get the equation of this perpendicular line from A(2, 5) to BC, we use the general equation of a line given in equation (i)

where;

m = 2

x₁ = 2

y₁ = 5

Substitute these values into equation (i)

y - 5 = 2(x - 2)

Solving by simplification gives;

y - 5 = 2x - 2

y = 2x + 3

Therefore, the equation of the perpendicular line is y = 2x + 3

25/2=12.5= π(12.5)=12.5 x 12.5= π(156.25)=

π = 490.87 x 4= 1963.48

Answer:

17.2 meters

Step-by-step explanation:

This is a right triangle problem

a^2 + b^2 = c^2

The 1st triangle:

a^2 + 10.1^2 = 12.2^2

a^2 = 12.2^2 - 10.1^2

a^2 = 46.83

a = 6.8432448444

The 2nd triangle

a^2 + 6.4^2 = 12.2^2

a^2 = 12.2^2 - 6.4^2

a^2 = 107.88

a = 10.3865297381

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

Width = 6.8432448444 + 10.3865297381

Width = 17.2297745825

Width ≈ 17.2 meters
