A baseball team played 154 regular season games. The ratio of the number of games they won to the number of games they lost was

ELEN [110]

Answer:

Number of games won = 110

Step-by-step explanation:

Given:

Total games played = 154

The ratio of number of games won to number of games lost = $\frac{5}{2}$

Solution:

Let the number of games won be = $5x$

Thus, number of games lost = $2x$

The total games played can be given as = $5x+2x=7x$

Thus, we have:

$7x=154$

Dividing both sides by 7.

$\frac{7x}{7}=\frac{154}{7}$

∴ $x=22$

So, number of games won = $5\times 22 = 110$

Question: A doctor prescribes 600 milligrams of a therapeutic drug that decays by about 13% each hour. Write an equation in base

UkoKoshka [18]

Answer: A = 600( $0.87^{h}$ )

Step-by-step explanation:

The rate = 13% = 0.13

Let I be the initial value = 600 mg

The Equation will be

A = I (1 - R%) $x^{h}$

A = 600( 1 - 0.13) $x^{h$

A = 600( $0.87^{h}$ )
