Answers

Answer 1

Answer:

1. x = 3

2. x = 6

3. not sure

Step-by-step explanation:

5x +2 (x+7) =14x -7

First expand the expandables

5x +2x +14 =14x-7

7x +14 =14x -7

14x -7x =14+7

7x=21 . Divide both sides by 7

x=3.

Answer 2

Step-by-step explanation:

1. 5x +2x + 2*7 =14x-7

7x + 14 = 14x - 7

14 +7 = 14x - 7x

21 = 7x

21/7 =x

4 =x

I have 3 red markers, 3 blue markers, and 3 green markers. I take the caps off and put on the caps randomly. Find the expected number of markers that have the same color cap and marker.

Answers

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))

y1 = 35.75 and y2 = 12.75
x1 = 1 and x = 0

m = (35.75 - 12.75)/(1-0)

The mass of the particles that a river can transport is proportional to the fifth power of the speed of the river. A certain river normally flows at
a speed of 4 miles per hour. What must its speed be in order to transport particles that are 12 times as massive as usual? Round your
answer to the nearest hundredth.

Answers

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.

Answers

ANSWER : both angles are 60 degrees and x is equal to 8.
10x - 20 = 7x + 4
Move the terms
3x = 24
x= 8
Sub back in to find the value:
80 - 20 = 60
56 + 4 = 60

Please mark as brainliest

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.

Answers

Answer/Step-by-step explanation:

Problem 1:

✔️Type of angle = right angle

✔️Equation: (x + 4) + (3x + 2) = 90°

✔️value of x:

x + 4 + 3x + 2 = 90

Add like terms

4x + 6 = 90

4x = 90 - 6

4x = 84

x = 84/4

x = 21

✔️Angle 1 (x + 4):

Plug in the value of x

Angle 1 = 21 + 4 = 25°

✔️Angle 2 (3x + 2):

Angle 2 = 3(21) + 2 = 63 + 2 = 65°

Problem 2:

✔️Type of angle = right angle

✔️Equation: x + 2x = 90°

✔️value of x:

x + 2x = 90

Add like terms

3x = 90

x = 90/3

x = 30

✔️Angle 1 (x):

Angle 1 = x = 30°

✔️Angle 2 (2x):

Angle 2 = 2(30) = 60°

Problem 3:

✔️Type of angle = right angle

✔️Equation: (3x + 6) + 4x = 90°

✔️value of x:

3x + 6 + 4x = 90

Add like terms

7x + 6 = 90

7x = 90 - 6

7x = 84

x = 84/7

x = 12

✔️Angle 1 (3x + 6):

Plug in the value of x

Angle 1 = 3(12) + 6 = 42°

✔️Angle 2 (4x):

Angle 2 = 4(12) = 48°

Triangle abc is equilateral, solve for x and y​

Answers

Answer:

x = 4

y = 3

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

y = 3

Now as per the situation

4x = 3x + £7

x = £7

For natasha = 4(7) = 28

For krutika = 3(7) = 21
