Beth plays a video game in which she starts with 0 points. In round 1, she losses 31/2 points in round 2, she wins 281/2 points

Thepotemich [5.8K]

Answer:

$21\frac{1}{2} \ or\ 21.5$

Step-by-step explanation:

Given that:

Initial score of Beth = 0

Round 1 scores:

Points lost = $3\frac{1}{2} = 3.5$

Round 2 scores:

Points won = $28\frac{1}{2}=28.5$

Round 3 scores:

Points lost = $3\frac{1}{2} = 3.5$

To find:

The final score of Beth in the video game = ?

Solution:

Let us calculate the total points lost and total points won by Beth in the video game.

Then we will subtract the total points lost from the total points won to find the final score in the video game.

Total points won = 28.5

Total points lost = 3.5 + 3.5 = 7

So, final score = Total points won - Total points lost

Final score = 28.5 - 7 = 21.5 or $\bold{21\frac{1}{2}}$

A triangle has an area of 50cm its base is four times the height what is the height?

babunello [35]

So area=1/2 base times height
50=1/2 base times height
multiply both sides by 2
100=base times height
base=4height
100=4height times height
100=4height^2
divide 4
25=height^2
squarer root
5=height

subisute
base=4(5)
base=20

height=5
