24 To raise money for charity, Jalaj walks 22 km, correct to the nearest kilometre, every day for 5 days.
(a) Complete the statement in the answer space for the distance, d km, he walks in one day.

Answers

Answer 1

The distance travelled by Jalaj in one day is 4.4 km.

Distance between two things or points is measured, and it can sometimes be quantitatively and sometimes qualitatively. The word "distance" in physics can refer to a physical length or, more commonly, to an estimate based on other factors (e.g. "two counties over").

The distance between any two points in space is equal to the length of the shortest path between them, or a straight line. This is the typical definition of distance in classical physics, especially in Newtonian mechanics.

Numerous techniques can be used to gauge straight-line lengths. Over instance, it can be done directly with a ruler or indirectly (for long distances) using interferometry or a radar (for very short distances). The cosmic distance ladder is a set of techniques for measuring extremely long distances.

Jalaj walks 22 km in 5 days.

Therefore in one day the distance travelled ,  d = 22 ÷ 5 = 4.4 km

Hence the total distance travelled in 1 day is 4.4 km.

A solution to the equation 4x+2y=20 must also be a solution to which of the following equations?1) 8x+2y=402) 2x+2y=103) 2x+y=104) 4x+4y=40

Answers

As given by the question,

There are given that the equation:

\(4x+2y=20\)

Now,

First, suppose any number, for which the given equation has satisfied.

So, the number is, x = 2 and y = 6

Then,

Put both values into the given equation

\(\begin{gathered} 4x+2y=20 \\ 4(2)+2(6)=20 \\ 8+12=20 \\ 20=20 \end{gathered}\)

Then,

Put the same value of x and y into the given option and check whether it is satisfied:

So,

From option 3:

\(\begin{gathered} 2x+y=10 \\ 2(2)+6=10 \\ 4+6=10 \\ 10=10 \end{gathered}\)

Hence, the correct option is 3.

a song played for 2 minutes 58 seconds. how many seconds did the song play? responses 60 s 60 s 118 s 118 s 178 st 178 s 258 s 258 s

Answers

The song played for 2 minutes 58 seconds or 178 seconds.

Therefore, the answer is 178 seconds.

Explanation:

Time is measured in minutes, seconds, and sometimes hours. For instance, when we want to know how long it took for a trip to a particular location, we can measure the time in hours and minutes.

We may also measure how long it took someone to finish a task in minutes and seconds.

To convert minutes to seconds, we use the formula:

1 minute = 60 seconds.

If a song played for 2 minutes 58 seconds,

we can convert it into seconds by multiplying 2 by 60, then adding 58 to get the total seconds played.

That is:

2 minutes * 60 seconds/minute

= 120 seconds58 seconds

Therefore, the total seconds played is 120 seconds + 58 seconds = 178 seconds.

Therefore, the answer is 178 seconds.

The exchange rates between pounds, Singapore dollars and Hong Kong dollars are shown below. 1 Singapore dollar = £0.58 £1 = 10.50 Hong Kong dollars Tsion bought a watch in Singapore for 72 Singapore dollars. Ibrahim bought the same model of watch in Hong Kong for 399 Hong Kong dollars. What is the difference between the amounts that Tsion and Ibrahim paid for their watches? Give your answer in pounds.

Answers

The Difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

To find the difference in the amounts that Tsion and Ibrahim paid for their watches, we need to convert the prices to the same currency. We can use the exchange rates given to convert both prices to pounds.

1 Singapore dollar = £0.58

72 Singapore dollars = 72 x £0.58 = £41.76

1 Hong Kong dollar = £0.09

399 Hong Kong dollars = 399 x £0.095 = £37.91

Therefore, Tsion paid £41.76 for the watch and Ibrahim paid £37.91 for the same model of watch.

To find the difference in the amounts paid, we can subtract the smaller amount from the larger amount:

£41.76 - £37.91 = £3.85

Therefore, the difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

A. 1 cm by 6 cm

B.2 cm by 5 cm

C. 3 cm by 4 cm

D. 4 cm by 3 cm

E. 5 cm by 2 cm

F. 6 cm by 1 cm

The perimeter is given as:

\(\mathbf{ Perimeter = 14cm}\)

The perimeter of a rectangle is:

\(\mathbf{Perimeter = 2 \times (Length + Width)}\)

So, we have:

\(\mathbf{A.\ Perimeter = 2 \times (1cm+ 6cm) = 14cm}\)

\(\mathbf{B.\ Perimeter = 2 \times (2cm+ 5cm) = 14cm}\)

\(\mathbf{C.\ Perimeter = 2 \times (3cm+4cm) = 14cm}\)

\(\mathbf{D.\ Perimeter = 2 \times (4cm+3cm) = 14cm}\)

\(\mathbf{E.\ Perimeter = 2 \times (5cm+2cm) = 14cm}\)

\(\mathbf{F.\ Perimeter = 2 \times (6cm+1cm) = 14cm}\)

\(\mathbf{G.\ Perimeter = 2 \times (7cm+7cm) = 28cm}\)

\(\mathbf{H.\ Perimeter = 2 \times (8cm+6cm) = 28cm}\)

By comparing the options with the given perimeter, the correct dimensions are:

A. 1 cm by 6 cm

2) 1 m/s and 0 m/^2 (Disk spins at constant speed)

3) 0.1 m/s and 1 m/s^2

4) 1 m/s and 10 m/s^2

Answers

A disk with a radius of 0.1 m is spinning about its center with a constant angular speed of 10 rad/sec. The speed of the bug is equal to the tangential speed of a point on the rim of the disk, which can be given by: v = rωWhere:r = 0.1 m (the radius of the disk)ω = 10 rad/sec (the angular speed of the disk)Therefore, the speed of the bug is: v = rω= 0.1 m x 10 rad/sec= 1 m/s

The acceleration of the bug can be given by: a = rαWhere:α = α (angular acceleration)The angular acceleration is zero because the disk is spinning at a constant angular speed. Hence, the acceleration of the bug is zero or a = 0 m/s². Therefore, the correct option is option 2) 1 m/s and 0 m/s² (Disk spins at a constant speed).

A driver travels for 4 hours at 88 miles per hour
during which his car gets 40 miles per gallon of
gasoline. He is paid $0.60 per mile, and his only
expense is gasoline at $3 per gallon. What is his net
rate of pay, in dollars per hour after this expense?

Answers

Total miles: 4 hours x 88 miles per hour = 352 miles

Pay = 0.60 per mile x 352 miles = $211.20

Gallons of gas used = 352 miles / 40 miles per gallon = 8.8 gallons

Cost of gas  = 8.8 gallons x 3 per gallon = $26.40

Net pay = amount paid - amount spent

Net pay = 211.20 - 26.40 = 184.80

Answer: $184.80

His net rate of pay in dollars per hour is $ 22.8 per hour.

Since the driver travels 4 hours at 88 miles per hour, the total distance he travels is d = speed × time

= 88 miles per hour × 4 hours

= 352 miles.

Since he is paid $0.60 per mile, the total amount he is paid for covering 352 miles is t = rate × distance

= $0.60 per mile × 352 miles

= $211.2.

Since his car gets 40 miles per gallon and he spends $ 3 per gallon, the total amount he spends on gasoline is t' = diatance per gallon × amount per gallon

= 40 miles per gallon × $ 3 per gallon

= $ 120.

So, his net pay T = total amount paid - amount spent on gasoline

= t - t'

= $211.2 - $120

= $91.2

Now, his net rate of pay in dollars per hour is p = net pay/total time of travel = $ 91.2/4 hours

= $ 22.8 per hour

So, his net rate of pay in dollars per hour is $ 22.8 per hour.
