Answer:

<h2>13 and 23</h2>

Step-by-step explanation:

let 2 number be x and y

x + y = 36 ---- equation ( 1 )

x - y = 10 -----equation ( 2 )

from ( 1 ) and ( 2 )

2y = 26

y = 13

<em>p</em><em>u</em><em>t</em><em>t</em><em>i</em><em>n</em><em>g</em><em> </em><em>v</em><em>a</em><em>l</em><em>u</em><em>e</em><em> </em><em>o</em><em>f</em><em> </em><em>Y</em><em> </em><em>i</em><em>n</em><em> </em><em>e</em><em>q</em><em>u</em><em>a</em><em>t</em><em>i</em><em>o</em><em>n</em><em> </em>( 1 )

x + y = 36

x + 13 = 36

x = 36 - 13

x = 23

18 bikes, 9 have gears (G), 11 have suspension (S) and 5 with both,What is the probability that a bike with suspension or gears?
vichka [17]

Answer:

  • 5/9

Step-by-step explanation:

  • Total number of bikes = 18
  • Bikes with gears S = 9
  • Bikes with suspension S = 11
  • Bikes with both GS = 5

<u>From the information above we have:</u>

  • Bikes with gears only = 9 - 5 = 4
  • Bikes with suspension only = 11 - 5 = 6

<u>Sum of the above two gives us the number of bikes with suspension or gears:</u>

  • 4 + 6 = 10

<u>Probability of selected bike be G or S is:</u>

  • P(G or S) = 10/18 = 5/9

An art museum has 1042 pictures of split equally into 45 different exhibits how many more pictures does a museum need to make su
tatyana61 [14]
He needs 1080 I believe so 38
because 1042 divided for 45 museums would be 23.15 meaning it wouldn't be the same amount for all
but if they get 38 pictures (1080) and divide it between the 45 museums it would be an even number of 24
so the answer is 38 more pictures

What's the circumference of a circle that is 9cm? Please explain step by step of how you got the answer...
Sauron [17]

Formula for finding circumference of a circle is 2πr.

Step-by-step explanation:

  • The given question says what is the circumference of a circle that is 9cm.
  • As radius is required for finding circumference of a circle, the formula is 2πr.
  • Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
  • If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
  • So the circumference of the given circle would be 18π or 56.52 cms.
