Question

Mathematics
1 answer:
Ahat [919]3 years ago

Answer:

4 minutes.

Step-by-step explanation:

There are three trains that Rachel has to take to go to her job. The total time is taken by her, on average, 1 hour and 20 minutes i.e. (60 + 20) = 80 minutes.

In his journey, she walks for 15 minutes and a train journey for about 53 minutes.

Then the total waiting time for the trains is (80 - 53 - 15) = 12 minutes.

Therefore, the average waiting time, in minutes, at each of the three train stations will be \frac{12}{3} = 4 minutes. (Answer)

Joe used 16 ounces of dark chocolate while baking. He used to fifths of the chocolate to make some frosting and use the rest to
Oduvanchick [21]
He used 16 oz of dark chocolate........he used 2/5 to make frosting....meaning he used 3/5 for the brownies.

2/5(16) = 32/5 = 6.4 oz for frosting
3/5(16) = 48/5 = 9.6 oz for the brownies

Therefore, he used (9.6 - 6.4) = 3.2 more oz in the brownies then in the frosting

Please help fast i have no clue what this is meaning<br> ILL MARK U BRAINLIEST
Klio2033 [76]

Answer:

A function is a relation that is either

  1. one-to-one, meaning each output only has one input
  2. many-to-one meaning some outputs can have more that one input, but all inputs only have one output

So, That pic is cramped, don't even know what functions are being referenced but

from the a, b, c, d relation

  • It is not a function because some inputs have more that one output, which fails our man-to-one rule

From the equations

  • -3x = 15 is not a function, because it only has one input but more than one output breaking rule 1
  • 2y=10 is a function because every input x has only one output y, it is many-to-one
  • 3x-0.25y=3 is a function, it is one to one

From the graph

  • the line is a function, since it is many-to-one

From the points

  • the x coordinate is the input, not points (2,6) and (2,3) have the same input for two outputs, breaking rule 2, that each input should have only one output. So the points are not a function

Write the ratio as a fraction in simplest form.<br><br> $5.40 for 24 cans (per can)
galina1969 [7]

Answer:

9/40

Step-by-step explanation:

To find the price per can, we take the cost and divide by the number of cans

$5.40/24

5.4/24

Since there is a decimal in the numerator, multiply the top and bottom by 10

5.4/24 * 10/10

54/240

Divide the top and bottom by 6

9/40
