Mathematics

Vladimir79 [104]3 years ago
3 0

Answer:

5 days

Step-by-step explanation:

This questions involves ratios, the job with 30 men can be done in 15 days, so the ratio from amount of men to amount of days the job will take to complete, it is 30:15. If we had 10 men instead of 30, 10 is one-third of 30, so you have to divide by 3 on each side of the ratio to get your answer.

If we do that we get the ratio 10:5.

Meaning that the 5 is the amount of days needed to be taken in order the complete the job.

Hope this helps!

At the ice cream shoppe,
motikmotik

Answer:

  $2.59

Step-by-step explanation:

Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...

  b +5m = 16.24

  3b +2m = 15.05

Subtracting the second equation from 3 times the first, we have ...

  3(b +5m) -(3b +2m) = 3(16.24) -(15.05)

  13m = 33.67 . . . . . . simplify

  m = 2.59 . . . . . . . . . divide by 13

The cost of a milkshake is $2.59.

A fish store can place 5 fish in each fish bowl. If there are 263 fish to place, how many fish bowls are needed for all 263 fish
skad [1K]

Answer:

Step-by-step explanation:

1 bowl holds 5 fish

x bowls hold 263 fish

1/x = 5/263                      Cross multiply

5x = 263                         Divide by 5

5x/5 = 263/5

x = 52.6

So you actually need 53 fishbowls. One of them holds only 3 fish

Maria Louisa looks at a sequence of shapes and records the number of vertices in each of the shapes in the sequence. The first s
seropon [69]

Step-by-step explanation:

arithmetic sequence.

an = an-1 + c = a1 + (n-1)c

c is in our case 2 (every new shape has 2 more vertices).

we have a a1 = 3.

an = 3 + 2(n-1)

so,

a21 = 3 + 2(20) = 3 + 40 = 43

the 21st shadow will have 43 vertices.
