Evan, Claire, Jaya and Tim are running a 3km relay race.

Mathematics
1 answer:
Kruka [31]3 years ago
5 0

Answer:

Tim needs to finish 59/90

Step-by-step explanation:

Add together what Evan Claire and Jaya ran  

9/10 + 7/9+ 2/3

The common denominator is 90

9/10 (9/9) +7/9 *10/10  + 2/3 *30/30

81/90 + 70/90 + 60/90

211/90

We need 3 km = 3 *90/90 = 270 /90

270/90 - 211/90 = 59/90

How many three letter arrangements can be made from the letters of<br> COMPLEXITY?*
Natali [406]

Answer:

720 arrangements

Step-by-step explanation:

We have three spaces that we want to fill with any letter from "complexity":

__ __ __

For the first space, we have 10 letters to choose from (there are 10 letters in the word "complexity"). For the second space, since we have already used up one letter for the first space, we have 9 letters remaining to choose from. Similarly, we only have 8 letters remaining to choose from for the last space.

Now, we multiply them all together: 10 * 9 * 8 = 720 arrangements.

Note that we multiply instead of add. This is because for any letter we place in space 1, it can be paired with any of the 9 letters for space 2 and any of the 8 letters for space 3.

Hope this helps!

4) Oceanside Bike Rental Shop charges $17 plus $6 an hour for renting a
Tresset [83]

Answer:

It is 7

Step-by-step explanation:

y = mx+b

y is the total cost.

x is the number of hours.

b : that's 16 dollars.

y = 9x+16

 

The problem states that the cost was 79 dollars.

Substitute that for y and solve for x.

79 = 9x+16

63 = 9x

x = 7 hours
