Two runners are saving money to attend a marathon. The first runner has $112 in savings, received a $45 gift from a friend, and

sergiy2304 [10]

Answer: it would take 3.1 months

Step-by-step explanation:

Let m represent the number of months that that it will take either of the runners to have the same amount of money in their accounts.

Let y represent the total amount that runner 1 saves for m months

Let z represent the total amount that runner 2 saves for m months

The first runner has $112 in savings, received a $45 gift from a friend, and will save $25 each month. This means that the total amount that he will save for m months would be

y = 112 + 45 + 25m

y = 157 + 25m

The second runner has $50 in savings and will save $60 each month. This means that the total amount that he will save for m months would be

z = 50 + 60m

To determine the number of months before the amount in the account of both runners becomes the same, we would equate y to z. It becomes

157 + 25m = 50 + 60m

157 - 50 = 60m - 25m

35m = 107

m = 107/35

m = 3.06

Answer:

Option A $\sqrt{187.95}\ Km$

Step-by-step explanation:

we know that

Applying the Pythagorean Theorem

$c^2=a^2+b^2$

where

c is the greater side (the hypotenuse)

a and b are the legs

we have

$a=3.7\ Km$ ----> the height of the airplane

$c=14.2\ Km$ ---> slant distance from the airport

substitute

$14.2^2=3.7^2+b^2$

solve for b

$b^2=14.2^2-3.7^2$

$b^2=187.95$

$b=\sqrt{187.95}\ Km$

In one lottery game, contestants pick five numbers from 1 through 23 and have to match all five for the big prize (in any order)

mihalych1998 [28]

The probability of matching three out of five numbers is 153/33649

<h3>How to determine the probability?</h3>

The numbers are given as:

1 to 23

There are five matching numbers

The probability of getting a match is:

p = 5-k/n where k = 0, 1, 2

While the complement probability is

q = (n - 2)/n

Using the above formulas, the probability of getting from 5 is:

P = 5/23 * 4/22 * 3/21 * 18/20 * 17/19

Evaluate the product

P = 153/33649

Hence, the probability of matching three out of five numbers is 153/33649
