Answer:

P(red) = 1/6

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

One bag contains black, red and green pearls in a ratio of 3:2:7.

So

[tex]\frac{3}{3+2+7} = \frac{3}{12}[/tex] of the pearls are black

[tex]\frac{2}{3+2+7} = \frac{2}{12}[/tex] of the pearls are red.

[tex]\frac{7}{3+2+7} = \frac{7}{12}[/tex] of the pearls are green.

P (red)

For each 12 pearls, 2 are red. So

P(red) = 2/12 = 1/6

Step-by-step explanation:

r = 7 ft

θ =  (26/180)π = (13/90)π radians

arc length = rθ = 7×(13/90)π = (91/90)π ft

Answer:

A

Step-by-step explanation:

four of the sides are equal to 18mm, so that would be the 4(18mm), and then the two other sides are equal to 24mm, which is 2(24mm). Your full equation would be:

P= 4(18mm) + 2(24mm)

A

Answer:

P = 4(18 mm) + 2(24 mm)

Answer:

x = 16√3

y = 8√3

Step-by-step explanation:

First, to figure out x, put the side we already know (24) over the cosine of the angle we know (30).

x = 24/cos(30)

(cos(30) is the same as √3/2)

x = 24/√3/2

Step 1: Multiply by 2/√3

x = (24 * 2)/√3

Step 2: Rationalize the denominator by multiplying by √3

x = √3(24 * 2)/√3 * √3

Step 3: √3 squared is 3.

√3(24 * 2)/3

Step 4: Multiply 24 by 2 to get 48.

x = √3(48)/3

Divide √3(48) by 3 to get 16√3

x = 16√3

Before we figure out y, we need to find you what 16√3 squared is.

((16(√3))²

Step 1: Expand the above equation.

16²(√3)²

Step 2: Square 16 to get 256.

256(√3)²

Step 3: √3 squared is 3.

256(3)

Step 4: Multiply 256 by 3 to get 768.

768

Now, subtract 576 (24 squared) from 768 to get 192. Find the square root of that, which is 8√3. (192 = 8² * 3; rewrite as √8²√3, then take the square root of 8²

Answer:

The characteristics of the parabola are;

1) The vertex of the parabola, (h, k) = (-8, 1)

2) The parabola opens left

3) The axis of symmetry is, y = 1

4) The equation of the parabola is x = -y²/8 + y/4 - 65/8

5) The end points of the latus rectum are (-10, -3), and (-10, 5)

Step-by-step explanation:

The focus of the parabola = (-10, 1)

The directrix of the parabola, x = -6

The directrix; x = h - p

The focus, F(h + p, k)

Therefore, we have;

h + p = -10

h - p = -6

2·h = -16

h = -8

p = -10 - h = -10 - (-8) = -2

p = -2

Therefore, we have;

1) The vertex of the parabola, (h, k) = (-8, 1)

2) Therefore, the parabola opens left

3) The axis of symmetry is the line y = 1

For P < 0, the equation of the parabola is of the form (y - k)² = 4·p·(x - h)

Therefore, the equation of the parabola is (y - 1)² = 4×(-2)×(x - (-8))

(y - 1)² = 4×(-2)×(x - (-8)) = y² - 2·y + 1 = -8·x - 64

∴ y² - 2·y + 1 + 64 = -8·x

x = -y²/8 + y/4 - 65/8

4) The equation of the parabola is x = -y²/8 + y/4 - 65/8

5) The end points of the latus rectum are (h + p, k + 2·p) and (h + p, k - 2·p)

Therefore, the end points of the latus rectum of the given parabola are;

(-8 + (-2), 1 + 2×(-2)) and (-8 + (-2), 1 - 2×(-2))

(-10, -3), and (-10, 5)

Answer:

The equation of the perpendicular line of the given line is

 [tex]y = \frac{-5}{6} x -\frac{1}{2}[/tex]

Step-by-step explanation:

Step(i):-

Given the equation of the line

         [tex]y = \frac{6}{5} x + \frac{4}{5}[/tex]

cross-multiplication, we get

       5y = 6x +4

The equation of the straight line is 6x - 5y +4=0

The equation of the perpendicular line to the given line is

                        b x - ay +k=0

The equation of the perpendicular line to the given line is   -5x-6y +k=0

This line passes through the point (-3,2)

    ⇒       - 5(-3) -6(2)+k=0

     ⇒       15 -12 +k=0

     ⇒              3 +k=0

       ⇒              k =-3

Step(ii):-

The equation of the perpendicular line is

                                  -5x-6y-3=0

                                  5x + 6y +3 =0

                                        6y = -5x-3

                                          [tex]y = \frac{-5}{6} x -\frac{3}{6}[/tex]

Final answer:-

The equation of the perpendicular line of the given line is

 [tex]y = \frac{-5}{6} x -\frac{1}{2}[/tex]

Answer:

The sidelength of the triangles is 6 feet and 8 feet.

Step-by-step explanation:

Given that,

The Hypotenuse of a right triangle = 10 feet

Let the shorter leg is x. It means the longer leg is (x+2).

For a right triangle,

Hypotenuse²=base²+perpendicular²

So,

[tex]10^2=x^2+(x+2)^2\\\\100=x^2+x^2+4+4x\\\\100=2x^2+4x+4\\\\2x^2+4x+4-100=0\\\\2x^2+4x-96=0\\\\x^2+2x-48=0\\\\(x+8)(x-6)=\\\\x=-8,6[/tex]

The side length of a triangle can't be negative. It means that the length of the shorter length is 6 feet and that of the longer leg be 8 feet.

Answer:

y= -2/3x +4

Step-by-step explanation:

(0,4) and (6,0)

m= (y2-y1)/(x2-x1)

m= (0-4)/(6-0)

m= -2/3

y-y1=m(x-x1)

y-4= -2/3(x-0)

y-4= -2/3x

y= -2/3x +4

Answer:

D

Step-by-step explanation:

Almost positive it's D. When you take two points on the line, you'll get a slope of 2/3. Since it's going down left to right, it's going to be negative. SOOO -2/3. The y-intercept is 4 because, well that's where the line crosses the y-axis.

Answer:

$35.53

Step-by-step explanation:

1. Divide what Kelly paid by the amount of gallons she paid for.

a. 29.26 divided by 14 = 2.09

2. Take the amount per gallon and multiply it by 17.

a. 17 times 2.09 = 35.53

So it will be $35.53 for 17 gallons of gas.

Answer:

35.53

Step-by-step;

So Kelly got 14 gallons of gas for 29.26. She is wondering how much it would be to fill it up to 17 gallons. So what you have to do is first find out how much the gas cost per gallon. so you would divide 29.26 by 14 to get 2.09. so now that you have how much it is per gallon all you have to do is multiply the amount per gallon {2.09} by 17. so when you multiply 2.09 by 17 you get 35.53. So Kelly had to pay 35.53 for a 17 gallon tank of gas!

Hope this helps you!

Answer:

4 lbs left after 5 days

Step-by-step explanation:

First, you need to step up an equation!

You know that Soomin has a total of 20 pounds and that she's using it, so you are going to use subtraction.

She uses 3 1/5 pounds per day so you write:

20 - 3 1/5x

and you know that she wants to know how much she has left after 5 days so you replace the x with 5:

20 - (3 1/5) * 5

Multiply first:

20 - 16

After Subtracting you get the answer:

4 lbs left

Answer:

4 lbs

Step-by-step explanation:

If she gives 3.2 each day you can multiply by 5 to get 16 then subtract 20 - 16 to get 4

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Penny buys 3 bouquets of flowers for $3 each and 4 bouquets for $2 each.

The expression that gives the total cost of the bouquets that Penny buys will be:

= (3 × $3) + (4 × $2)

Solving further will be:

= (3 × $3) + (4 × $2)

= $9 + $8

= $17

Answer:

son = 10 , father = 40

Step-by-step explanation:

Let Five years ago the age of son be x years and age of father be 7x years

Present age of son =x+5

Present age of father =7x+5

5 years later their age will (x+10) and (7x+10)

∴7x+10=3(x+10)

7x−3x=20

4x=20

x=5

So, the present age of son=x+5=5+5=10years

and the present age of father=7x+5=35+5=40years

Answer:

6.33

Step-by-step explanation:

Given the coordinates;

G(-4,2), O(5,-1), and T(10,8).

Midpoint of GT is expressed as;

M = (-4+10/2, 2+8/2)

M = (6/2, 10/2)

M = (3, 5)

Hence the midpoint of GT is (3,5)

Find the length of M and O

M (3,5) and O(5,-1)

MO = √(3-5)²+(5+1)²

MO = √2²+6²

MO = √4+36

MO = √40

MO  = 6.33

Hence the length of the segment joining the midpoint of GT and O is 6.33

The  length of the segment joining the midpoint of GT and O is 6.33.

Midpoint of GT is expressed as;

[tex]M = (-4+10\div 2, 2+8\div 2)\\\\ = (6\div 2, 10\div 2)[/tex]

 = (3, 5)

Hence the midpoint of GT is (3,5)

Find the length of M and O

M (3,5) and O(5,-1)

[tex]MO = \sqrt (3-5)^2+(5+1)^2\\\\= \sqrt(2^2+6^2)\\\\= \sqrt 4+36\\\\= \sqrt 40[/tex]  

= 6.33
