Why is 40x-16 not equivalent?
Please help (i’m in 7th grade)

Answer:

6.58 miles per hour

Step-by-step explanation:

Let the mass and speed be represented by m and s respectively. So that,

m [tex]\alpha[/tex] [tex]s^{5}[/tex]

m = k[tex]s^{5}[/tex]

where k is the constant of proportionality.

For a certain river, speed = 4 miles per hour.

m = k [tex](4)^{5}[/tex]

m = 1024k ............ 1

In order to transport particles that are 12 times as massive as usual;

12m = k[tex]s^{5}[/tex]

m = [tex]\frac{ks^{5} }{12}[/tex] ............. 2

Thus,

[tex]\frac{ks^{5} }{12}[/tex] = 1024 k

[tex]s^{5}[/tex] = 12 x 1024

   = 12288

[tex]s^{5}[/tex] 12288

s = [tex]\sqrt[5]{12288}[/tex]

  = 6.5750

s = 6.58 miles per hour

Therefore, its speed must be approximately 6.58 miles per hour.

Answer:

The expected number of markers that have the same color cap and marker is 3.

Step-by-step explanation:

Every marker has a [tex]\frac{1}{3}[/tex] chance to get the same color cap, because there are always 3 same caps, and 9 total caps. By linearity of expectation, the expected number of markers that have the same color cap and marker is equal to the sum of all marker's individual 'contribution' to the same color cap count. So the expected value is [tex]9 \cdot \frac{1}{3} = 3[/tex], precisely what we were after.

Answer:

3

Step-by-step explanation:

By running the following Python code, we can safely assume the answer to be 3:

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

import random

def cap_throw():

   cap_list = ['R', 'R', 'R', 'G', 'G', 'G', 'B', 'B', 'B']

   random_cap_list = cap_list[:]

   random.shuffle(random_cap_list)

   counter = 0

   for i in range(len((cap_list))):

       if cap_list[i] == random_cap_list[i]:

           counter += 1

   return counter

results_list = []

for i in range(10 ** 6):

   results_list.append(cap_throw())

print(sum(results_list) / len(results_list))

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

Which gave 2.998795.

Answer:

x = 3.2

Step-by-step explanation:

Since, intercepts made by parallel lines on the transversals are in proportion.

[tex] \therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)[/tex]

AB = BC.... (given)

[tex] \implies \frac{AB}{BC} = 1..... (2)[/tex]

From equations (1) & (2)

[tex] 1 =\frac{EF}{FG}[/tex]

[tex] {FG}={EF}[/tex]

Therefore,

7x - 9 = 2x + 7

7x - 2x = 9 + 7

5x = 16

x = 16/5

x = 3.2

Step-by-step explanation:

Remark

If a triangle is equilateral all three sides are equal. So each side has equal statements.

Solution

3x + 2 = 5x - 2y            Subtract 3x from both sides

2 = 5x -3x - 2y              Combine

2 = 2x - 2y                     divide by 2

x - y = 1                          Equation 1

3x + 2 = 6y - 4            Equilateral triangles have equal sides. Subtract 6y

3x - 6y + 2=  - 4          Subtract 2

3x - 6y = -4 - 2

3x - 6y = - 6                Divide by 3

x - 2y = - 2                  Equation 2.

Now subtract equation 1 from equation 2

x - 2y = - 2

x -  y    =  1                    Subtract

  - y    = - 3                   Multiply by -2

    y = 3

Put y = 3 into equation 1

x - y = 1

x - 3 = 1                         Add 3 to both sides.

x = 4

Answer

x = 4

The measure of each marked angle is 60 degrees for the given figure, which are alternate exterior angles.

The angles are given as:

∠1 = 10x-20 and ∠2 = 7x+4

As we know that alternate exterior angles are described as the pair of angles formed on the outer side of the parallel lines and on opposite sides of the transversal when two parallel lines are crossed by a transversal.

By alternate exterior angles, it can be written as:

∠1 = ∠2

10x-20 = 7x+4

10x -7x = 4 + 20

3x = 24

x = 24/3

x = 3

From given angles:

80 - 20 = 60

56 + 4 = 60

Thus, the measure of each marked angle is 60 degrees.

Answer:

1400

Step-by-step explanation:

There is a flat fee involved, which is the y-intercept of the line.

The line eats the points:

(3, 435)

 and

(5, 625)  

the slope is 190/2 = 95

 B = y - mx = 435 - (95)(3)

                 = 435 - 285

                 =  150

The linear function is:

y = 95x + 150

So for x=2, it will cost

95(2) + 150 = 190 + 150 = 340

435 + 625 + 340 =  1400

The total cost to rent the boat for three days is $1400.

Given that, on Saturday, he rented a pontoon boat for three hours and paid $435.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The cost for the rented a pontoon boat for five hours is 435+190 = 625

The coordinate points are (3, 435) and(5, 625)  

The slope is m = (625-435)/(5-3)

= 190/2 = 95

Now, b = y - mx = 435 - (95)(3)

= 435 - 285 =  150

So, the linear function is y = 95x + 150

So for x=2, it will cost

95(2) + 150 = 190 + 150 = 340

Total cost = 435 + 625 + 340 = 1400

Therefore, the total cost to rent the boat for three days is $1400.

Answer:

5,720,000 Sq Feet.

Step-by-step explanation:

They are asking the Area of a Trapezoid

Equation =( base + base / 2) x height

Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.

So if you multiply them (200 x 260) You will get 52000.

Now we divide that by 2. (52000 / 2 = 26000)

Now it says the straight line is 220. I think this refers to the height.

Now we multiply 26000 x 220. Which is 5720000.

Its a pretty big number, but that is the answer! :)
