Both the train will meet after 36 minutes.

<h3>Concept:</h3>
  • To find when both the train will meet again at the same time, we need to find the LCM of the frequency.

<h3>How to solve the given question?</h3>
  • Frequency of express train = 9 minutes = 3 × 3
  • Frequency of local train = 12 minutes = 2 × 2 × 3
  • LCM = 2 × 2 × 3 × 3 = 36

Thus, both the train will meet after 36 minutes.

Jim have the shopkeeper six coins that totaled 38 cent for a balloon what were the six coins
Katyanochek1 [597]

We are given that

Shopkeeper has six coins

total number of coins =6

we know that

there are four types of coins

(1) cents

1 cent =1 cent

(2) nickels

1 nickel =5 cents

(3) dimes

1 dimes =10 cents

(4) quarters

1 quarter = 25 cents

so, we can use trial and error method

Since, nickels , dimes and quarter are multiple of 5

and there 38 cents

so, three coins must be cent

number of cent coins =3

so, the remaining cent = 38-3=35

so, possible coins can be 1 quarter and 2 nickels

1 quarter + 2 nickels =25+2(5)=35

so, coins were

Number of cents =3

Number of nickels =2

Number of dimes =0

Number of quarter =1..................Answer

Carver jogs four times a wee. Last week, his distances were 4 1/3, 3 1/2, 3 5/6 and 4 1/6, all measured in miles. What was Carve
nevsk [136]
First, it have to change them so that they have common denominators. You would change the denominators to 6.
Your new fractions are:
4 2/6, 3 3/6, 3 5/6, 4 1/6.
Now you add them all together. When you add all of them, you end up with: 14 11/6. You would have to change this to 15 5/6.
Therefore, his average distance was 15 5/6 ( I think? ).

S varies inversely as G. If S is 8 when G is 1.5​, find S when G is 3. ​a) Write the variation. ​b) Find S when G is 3.
ss7ja [257]

Step-by-step explanation:

a.

s \:  =  \frac{k}{g}

8 =  \frac{k}{1.5}

k \:  = 1.5 \times 8 = 12

s =  \frac{12}{g}

b.

s =  \frac{12}{3}

s = 4
