A car wheel has a diameter of 20.8 inches.
m_a_m_a [10]

Answer:

  • 65.312 inches
  • 326.56 inches
  • 1959.36 inches

Step-by-step explanation:

<h3>Given</h3>
  • d = 20.8 inches
<h3>To find</h3>
  • Travel in 1, 5, 30 rotations
<h3>Solution</h3>

<u>Circumference of the wheel is equal to one full rotation</u>

  • C = πd = 3.14*20.8 = 65.312 inches
  • 5C = 5*65.312 = 326.56 inches
  • 30C = 30*65.312 = 1959.36 inches

To describe a specific arithmetic sequence, Elijah wrote the recursive formula:
11111nata11111 [884]

Answer:

t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........

Step-by-step explanation:

Given the arithmetic sequence in recursive formula.

f(0) = 30 and f(n + 1) = f(n) + 7 ......... (1)

Therefore, putting n = 0 in equation (1) we get f(1) = f(0) + 7 = 30 + 7 = 37 {Since, f(0) is given to be 30}

Again, putting n = 1 in equation (1) we get f(2) = f(1) + 7 = 37 + 7 = 44

And, putting n = 2 in equation (1) we get f(3) = f(2) + 7 = 44 + 7 = 51

and so on.

Therefore, the arithmetic sequence is 30, 37, 44, 51, .......

Therefore, the linear equation of this sequence is given by t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........

kicyunya [14]

Answer:

Senior citizen tickets = $9

Student tickets = $11

Step-by-step explanation:

We begin by converting these into simultaneous linear equation;

Senior citizen tickets = a

Student tickets = b

5a + 9b = 144

14a + 6b = 192

5a = 144 - 9b

a = 144/5 - 9b/5

a = 28.8 - 1.8b

We now substitute this into the first equation

14(28.8 - 1.8b) + 6b = 192

403.2 - 25.2b +6b = 192

-19.2b = 192 - 403.2

b = -211.2/-19.2

b = 11

Put the value of b into either equation

5a + 9b = 144

5a + 9(11) = 144

5a +99 = 144

5a = 144-99

5a = 45

a = 9

timurjin [86]

Answer:

Step-by-step explanation:

its really simple

just use your brain

4/4 makes 1 whole and 12-11=1 we need to convert the fraction into a whole number. So what over 4 makes 11 wholes? just do 4x11=44 and 44/4=11 and 12-11=1 just do the same for the other ones
