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

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:

  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.

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

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.

Scale factor = 1.5

Step-by-step explanation:

Formula for the scale factor,

Scale factor = [tex]\frac{\text{Measure of one side of the Image}}{\text{Measure of one side of the preimage}}[/tex]

In this question, image is triangle Y and preimage is triangle X.

Scale factor of X to Y = [tex]\frac{15}{10}[/tex]

                                    = 1.5

Therefore, scale factor = 1.5 is the answer.

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:

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.

Step-by-step explanation:

Two Squares

There are 2 squares at the top and bottom. All sides = 3

2* s^2

2 * 3^2

2 * 9

18

Middle Figure.

Triangles

There are many ways to solve this. I think the most easily understood is to break it into 2 triangles and a rectangle.

Base of both triangles = 5 + 5 = 10

The height of each triangle = (7 - 3)/2 = 4/2 = 2. You divide by 2 because there are 2 bases -- one in each triangle.

Area = 1/2 * 2 * 10 = 10

But there are 2 of them so the total area is 20

Rectangle

The length of the rectangle = 5 + 5 = 10

The width = 3

Area = 30

Total

Total Area = 2 squares + 2 triangles + 1 rectangle

Total Area = 18 + 20 + 30 = 68

Answer:

304

Step-by-step explanation:

The area of the square is 12 x 8 = 96.

There are two triangles with area (11x8)/2=44. 44x2=88.

There are two triangles with area (10x12)/2=60. 60x2=120.

96+88+120=304
