Answer:

The last graph best represents the story

Step-by-step explanation:

Mary left for school from rest. So the initial speed is zero.

So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.

When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.

After resting she still continued her journey to school.

This part also has a positive slope.

accurate as the precision below indicates. The weights are 1.21 kg, 546 mg, and 23.14 g. Using significant figures, the total ma
ryzh [129]

Answer:

1233.68 g

Step-by-step explanation:

Given:

The weights are

1.21 kg

546 mg

23.14 g

Here,

the units of all the weights given are not uniform, also the options are provided in grams

Therefore, we will first convert all the weights in the uniform unit i.e in grams

thus,

we have

1.21 kg = 1210 g

546 mg = 0.546 g

23.14 g

hence,

the total mass = 1210 g + 0.546 g + 23.14 g = 1233.686 ≈ 1233.68 g

Hence, the correct answer is option 4. 1233.68 g

● The short and long hands of a clock are 4 cm and 6 cm long respectively. Find the sum of distance travelled by their tips in 2
nekit [7.7K]

Step-by-step explanation:

short hand radius = 4

distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)

distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2

long hand radius= 6

each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution

distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7

distance in 48hr = 37.7 x 48= 1809.6 (approx)

so sum of both= 1809.6 + 50.2 = 1859.8
