Find total marbles:

8 + 15 + 17 = 40 total marbles.

There is 8 red, so picking red first would be 8/40, which can reduce to 1/5.

After taking 1 marble there would be 39 marbles left.

Picking blue would be 15/39, which reduces to 5/13

The probability of doing both is

1/5 x 5/13 = 5/65, which reduces to 1/13

The answer is B. 1/13

U =1/7pd

Multiplying through by 7pd, we have U7pd=1

Dividing through by U7d , we have p=U7d*1

Therefore p= U7d

Answer:

Number = 36

Step-by-step explanation:

Given that,

A number twice of which decreased by 7 gives 65.

Let the number be x.

Twice of the number is 2x.

ATQ,

2x - 7 = 65

We can solve the above equation.

Adding 7 both sides.

2x-7+7 = 65 +7

2x = 72

x = 36

So, the required number is 36.

Answer:

the answer is

y - 2y = 1/5

-y = 1/5

y = -1/5

Answer:

y=-1/5 or y=-0.2

Step-by-step explanation:

y=2y+1/5

-1/5=2y-y

-1/5=y

y=-1/5

Answer:

C. The shaded area represents both 2/3 and 6/9 of the whole shape.

Answer:

90

Step-by-step explanation:

4/15 which is our fraction distance/time

our other fraction is 24/x (x is our variable to find our time)

Now we are doing the buultterfly method

set it up

now multiply 4*x= 4x

15*24=360

now divide 4x ÷ 4 to get our variable alone

do the same to the other side

4 ÷ 360= 90

so x= 90 which is our missing number

Answer:

AE=22.4

Step-by-step explanation:

BE is 1/2 of BC

BC is 20 cm                 All sides of a square are equal

BE = 1/2 BC                  Property of a midpoint.

BE = 10

Now just use Pythagorus

AB^2 + BE^2 = AE^2

AE^2 = 20^2 + 10^2   Perform the sqrs

AE^2 = 400 + 100      Add the terms

AE^2 = 500                Take the square root of both sides

√AE^2 = √500

AE = 22.36

AE ≈ 22.4

Answer:

  a9 = -8 +9(9 -1)

Step-by-step explanation:

The given sequence has a common difference of 1-(-8) = 10-1 = 9, and a first term of -8. The formula for the n-th term of such an arithmetic sequence is ...

  an = a1 +d(n -1) . . . . . first term a1, common difference d

For the parameter of this sequence, a1=-8 and d=9, the n-th term is ...

  an = -8 +9(n -1) . . . . formula for the n-th term

__

Then the formula for the 9th term is ...

  a9 = -8 +9(9 -1)

Step-by-step explanation:

Absolute value is the distance that number is ways from zero

Answer:

45

Step-by-step explanation:

The absolute value of any number is the positive of that number.

Ex:

a) absolute value of |- 23 | is 23.

b) absolute value of 13 is 13 itself.

-Therefore absolute value is always positive.

Answer:

1/2

Step-by-step explanation:

As cosx= 2sinx,

now,

so, sinxcosx = sinx(2sinx) = 2 sin²x

Again,

2sin²x =1

sin²x= 1/2

sinx = 1/ root 2

sinx = sin 30

x = 30

Answer:

Similar triangles may or may not be congruent

The area of triangle DEF is 800 square cm

The given parameters is

[tex]\triangle ABC \sim \triangle D EF[/tex]

This means that the triangles are similar.

The corresponding sides of the triangles are:

[tex]AC = 6[/tex]

[tex]DF = 20[/tex]

So, the scale factor (k) from ABC to DEF is:

[tex]k = \frac{D EF}{ABC}[/tex]

[tex]k = \frac{20}{6}[/tex]

Simplify

[tex]k = \frac{10}{3}[/tex]

The area of triangle DEF is then calculated as follows:

Area = Area of triangle ABC * k^2

So, we have:

[tex]A =72 \times \frac{10}{3} \times \frac{10}{3}[/tex]

[tex]A = 800[/tex]

Hence, the area of triangle DEF is 800 square cm

Answer:

The amount to be paid for insurance will be $ 937,500. In this context, it is reasonable that insurance costs increase proportionally, as the ride will have a greater use and, therefore, a greater exposure to risk.

Step-by-step explanation:

Given that the amusement park Diablo's Domain ride generated $ 250,000,000 in revenue, and the company paid $ 750,000 in insurance for that game ($ 3 for every $ 1,000 in profit), to determine the amount of insurance that should be paid if the winnings increase by 25% and the same proportion of 3/1000 to be paid is maintained, the following calculation must be made:

(250,000,000 x 1.25) x (3/1000) = X

312,500,000 x 0.003 = X

937,500 = X

Therefore, the amount to be paid for insurance will be $ 937,500.

i will get it wrong too if it is wrong.

The measure of angle HGI from the given rhombus is 35°.

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.

The given quadrilateral FGHI is a rhombus.

In a rhombus, diagonals bisect each other at right angles.

Here, (7x-1)°+(4x+3)°+90°=180°

11x+92=180

11x=88

x=8

Now, 4x+3=35°

So, m∠HGI=35° (Alternate interior angles)

Therefore, the measure of angle HGI is 35°.

Answer: 14 tons

$3,860.50

Step-by-step explanation:

Let x = the amount of sugar transported.

First company:

The cost is $3157 truck rental plus $50.25 per ton of sugar.

Total cost = 3157 + 50.25x dollars

Second company:

There is no charge for truck rental, but it costs $275.75 per ton of sugar.

The total cost is

275.75x

When the two costs are the same, then

275.75x = 3157 +50.25x

225.5x = 3157

x = 14 tons

The total cost is 275.75*14 = $3,860.50

Answer:

16 pounds of sugar

The initial cost to transport it would be $4812

Okay

So lets do company 1=a

2=b

So the equation for company a is

3604+75.5x

The second one is

300.75x

Now I would find the LCM

So I just predicted (guess and check)

so obviously 15 can be a good shot but that off a little bit,

16

so if you plug in 16 for each options for X

3604+75.5*16= 4812

The second company

300.75*16=4812

SO their the same

So 4812 cost, 16 tons
