Answer:

33.51 cm

Step-by-step explanation:

240/360 = 2/3 (Arc length is 2/3 of the total circumference)

C = 2 $\pi$ r ( Calculate the total circumference)

C = 2(8) $\pi$

C = 50.265

2/3(50.265) (Take 2/3 of the circumference. times 2 divide by 3)

33.51

Use a calculator and leave the answer to C and then multiply and divide. You get a more precise answer.

Identify the slope (m) and y-intercept (b) of each linear equation.<br> 52. 3x+4y=24

nekit [7.7K]

Answer:

Step-by-step explanation:

[1] 3x - 4y = -24

[2] -x - 16y = -52

Graphic Representation of the Equations :

-4y + 3x = -24 -16y - x = -52

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = -16y + 52

// Plug this in for variable x in equation [1]

[1] 3•(-16y+52) - 4y = -24

[1] - 52y = -180

// Solve equation [1] for the variable y

[1] 52y = 180

[1] y = 45/13

// By now we know this much :

x = -16y+52

y = 45/13

// Use the y value to solve for x

x = -16(45/13)+52 = -44/13

Solution :

{x,y} = {-44/13,45/13}

I must also show my work, but I do not know how to do this problem

Vinvika [58]

Answer:

x = 10

Step-by-step explanation:

We know that the sum of angles in a triangle is equal to 180 degrees;

This means that

71+50+(6x-1) = 180; now that you have an algebraic expression, you can solve for x.

71+49+6x=180

120+6x = 180

6x = 60

x = 10

In how many ways can the letters in the word MATHEMATICS be reshuffled so that all consonants appear together?

steposvetlana [31]

Answer:

75600

Step-by-step explanation:

We are given that a word MATHEMATICS

Total letters =11

M repeated 2 times

T repeated 2 times

A repeated 2 times

Total vowels=4

Let MTHMTCS=P

Total number of ways in which MTHMTCS can be arranged= $\frac{7!}{2!2!}$

PAEAI

Total number of ways in which PAEAI can arranged= $\frac{5!}{2!}$

Total number of arrangements when all consonant appear together= $\frac{7!}{2!2!}\times \frac{5!}{2!}$

Total number of arrangements when all consonant appear together= $\frac{7!5!}{2\times 2\times 2}=\frac{7\times 6\times 5\times 4\times 3\times 2\times 1\times 5\times 4\times 3\times 2\times 1}{8}=75600$

By using formula ; $n!=n(n-1)(n-2)...2\times 1$
