The moon is about 382,500km away from Earth. This distance actually varies by about 22,500km. What are the maximum and minimum d
KiRa [710]

Answer:

The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km

Step-by-step explanation:

The maximum distance is found adding the variation.

The minimum distance is found subtracting the variation.

We have that:

Distance: 382,500 km

Variation: 22,500 km

So

Maximum distance: 382500 + 22500 = 405,000 km

Minimum distance: 382500 - 22500 = 360,000 km

The minimum distance to the moon is of 360,000 km and the maximum distance is of 405,000 km

Sarah sold a total of 178 t shirts and posters at a festival. She sold 46 more tshirts than poster. How many posters did she sel
ycow [4]

Sarah sold 66 posters

<em><u>Solution:</u></em>

Let "a" be the number of shirts sold

Let "b" be the number of posters sold

<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>

Therefore,

number of shirts sold + number of posters sold = 178

a + b = 178 ----------- eqn 1

<em><u>She sold 46 more tshirts than poster</u></em>

Number of shirts sold = 46 + number of posters sold

a = 46 + b --------- eqn 2

<em><u>Substitute eqn 2 in eqn 1</u></em>

46 + b + b = 178

2b = 178 - 46

2b = 132

b = 66

Thus she sold 66 posters

Tamiku [17]

Answer:

Probability of selecting red tile out of a box containing 3 red,2 white & 5 black tiles = 3/10 = 0.3

Step-by-step explanation:

Probability is the calculation of likelihood of an event.

It can be calculated by Formula : Favourable outcome / Total Outcomes

Example : If a box contain 3 red tiles, 2 white tiles, 5 black tiles

Prob (selecting a red tile) = Favourable outcome (red tiles) / Total Outcomes (total tiles) = 3 / 10 = 0.3

Similarly, prob (white tile) & prob (black tile) = 2/10 ie 0.2 & 5/10 ie 0.5 respectively
