Suppose that $b$ is a positive integer greater than or equal to $2.$ When $197$ is converted to base $b$, the resulting representation has $4$ digits. What is the number of possible values for $b$

Answers

Complete Question

Suppose that b is a positive integer greater than or equal to 2. When 197 is converted to base b, the resulting representation has 4 digits. What is the number of possible values for b?

The possible values of b are 4 and 5

How to determine the possible numbers of b?

The conditions are given as:

b is at least 2When 197 in base b has 4 digits.

So, we start by converting 197 to base 2 and above.

This is done as follows:

197 to base 2

2 | 197

98 R 1

49 R 0

24 R 1

12 R 0

6 R 0

3 R 0

1 R 1

0 R 1

So, we have:

197 = 11000101 in base 2

11000101 has more than 4 digits.

This means that b cannot be 2

Using the above method of conversion, we have:

197 = 21022 in base 3197 = 3011 in base 4197 = 1242 in base 5197 = 525 in base 6197 = 401 in base 7

See that as the base increases, the number of digits decreases.

The numbers in base 4 and 5 have 4 digits.

Hence, the possible values of b are 4 and 5

9. A box contains 50 discs which are numbered 1 to 50. If one disc is drawn at random from the box. Find the probability that it bears: a 2 digit no. (ii) a perfect square no. (iii) a no. divisible by 5

Answers

The probability that it bears a 2 digit no. is 41/50; a perfect square no is; 3/25; a no. divisible by 5 is; 0.2

How to find the probability?

We are given;

Number of Discs in box = 50

Type of discs in box = Numbered 1 to 50

i) Number of 2 digit numbers = 41

Thus;

P(2 digit numbers) = 41/50

ii) Perfect square numbers are; 4, 9, 16, 25, 36 and 49. Thus;

P(perfect square number) = 6/50 = 3/25

iii) Numbers divisible by 5 are; 5, 10, 15, 20, 25, 30, 35, 40, 45, 50.

Thus;

P(numbers divisible by 5) = 10/50 = 0.2

A rescue mission is being conducted using a plane to drop supplies and medical personnel. A helicopter
is also sent from the same base station to rescue wounded persons. If the plane flies 400 mph, the
helicopter flies 200 mph, and they leave at the same time, how far away is the rescue site if the
helicopter arrives 1 hour after the plane arrives?
If t represents the time that the plane flies, which of the following equations could be used to solve the
problem?
400/t = 200/(t+1)
400t = 200(t+1)
400t = 200t+1

Answers

400 miles away is the rescue site if the helicopter arrives 1 hour after the plane arrives and the expression 400t = 200(t + 1) represents the time that the plane flies option second is correct.

What is distance?

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

We have:

A helicopter is sent from the same base station to rescue wounded persons. If the plane flies 400 mph, the helicopter flies 200 mph, and they leave at the same time.

Let's suppose the plane takes t hours

We know,

Distance = speed×time

400×t = 200(t + 1)

400t = 200(t + 1)

After solving we get:

t = 1 hour

Distance = 400×1 = 400 miles

Thus, 400 miles away is the rescue site if the helicopter arrives 1 hour after the plane arrives and the expression 400t = 200(t + 1) represents the time that the plane flies option second is correct.

5/8 of a number is 200. What is 7/10 of the number ?

Answers

Answer:

224

Step-by-step explanation:

Let x be the unknown number.

(5÷8)x = 200

Then

x = (8×200) ÷ 5

= 1600 ÷ 5

=320

……………………………

(7/10)x = (7/10)×320

= (7×320) ÷ 10

= 224

Answer:

= 224

Step-by-step explanation:

Hi there!, here is how we solve the problem;

To begin, the question wants us to determine

[tex] \frac{7}{10} [/tex]

of the number x (unknown).

[tex] \frac{5}{8} = 200 \\ \frac{8}{8} = x \\ ( \frac{ \frac{8}{8} \times 200 }{ \frac{5}{8} } ) \\ = \frac{8}{8} \times 200 \times \frac{8}{5} \\ = 320 \\ x = 320[/tex]

We have found our x = 320

Lets now determine

[tex] \frac{7}{10} [/tex]

Which is given by;

[tex]( \frac{7}{10} \times 320 \\ = 224[/tex]

[tex] \frac{7}{10} [/tex]

of the number is therefore 224.

From the attached graph, the x-intercepts of the graph are:

x1 = -3

x2 = 0

x3 = 2

The equation of the graph is then calculated as:

f(x) = (x - x1)(x - x2)(x - x3)

This gives

f(x) = (x + 3)(x - 0)(x - 2)
