The St. Louis Cardinals defeated the Texas Rangers in the 2011 World Series in a thrilling 7game series. The matrices below show

KonstantinChe [14]

Answer:

The St. Louis Cardinals had the most total runs

The Texas Rangers had the most total hits

Step-by-step explanation:

From the given matrices, we have;

The total runs made by the St. Louis Cardinals is found by adding the runs obtained in each of the seven games as follows;

Total runs by St. Louis = 3 + 1 + 16 + 0 + 2 + 10 + 6 = 38

Similarly the total hits by the St. Louis Cardinals is given as follows;

Total hits by St. Louis = 6 + 6 + 15 + 2 + 7 + 13 + 7 = 56

For Texas Rangers, we have;

Total runs by Texas Rangers = 2 + 2 + 7 + 4 + 4 + 9 + 2 = 30

Total hits by the Texas Rangers = 6 + 5 + 13 + 6 + 9 + 15 + 6 = 60

Therefore, we have;

The St. Louis Cardinals has the most total runs with 38 runs which is more when compared to the Texas Rangers that have 30 runs

The Texas Rangers has the most total hits with 60 hits compared to the St. Louis Cardinals that have 56.

irena’s boat traveled 76 miles downstream in 4 hours. on the way back it took her 5 hours and 30 minutes to travel 38.5 miles. i

Oxana [17]

Answer:

The speed of the boat in still water is 13 miles/hour.

The speed of the current is 6 miles/hour.

Step-by-step explanation:

Let the speed of the boat in still water be x

And speed of the current be y

When Irena's travelling downstream, the speed of the boat is:

$Speed=\frac{76 miles}{4 hours}=19 miles/hour$

Traveling down stream the speed of the boat will be :

$x+y=19$ ..(1)

When Irena's travelling upstream, the speed of the boat is:

Time taken by boat = 5 hours and 30 min = 5.5 hours (1 hour = 60 min)

$Speed=\frac{38.5 miles}{5.5 hours hours}=7 miles/hour$

Traveling down stream the peed of the boat will be :

$x-y=7$ ..(2)

On Solving both equation (1)and (2).

$x+y=19$

$x=19-y$ putting value of x in (2) equation

$19-y-y=7$

y = 6 miles/hour

Putting value of y in (1) equation:

$x+6=19$ , x = 13 miles/hour

The speed of the boat in still water is 13 miles/hour.

The speed of the current is 6 miles/hour.

How do I solve: m-77 = 222

Alona [7]

Answer:

m = 299

Step-by-step explanation:

When isolating variables, you must do the same thing to both sides of the equation. To isolate "m", you must add 77 to both sides.

m - 77 = 222 <----- Original equation
+77 +77 <----- Add 77 to both sides

m + 0 = 299 <----- Resulting equation

m = 299 <----- Rewrite
