Answer:

The figure is a composite shape.

Theres 1 triangle and 1 rectangle

The formula to find the area of the triangle is 1/2 x base x height

1/2 x 7 x 3 = 10.5 units^2

The formula to find the area of the rectangle is base x height

7 x 3 = 21 units^2

Then add up all the areas to find the area of the entire shape.

10.5 units^2 + 21 units^2 = 31.5 units^2

In a ten pin bowling the highest possible score in a single game is 300. At one point in the season, John had an average score o
Sindrei [870]

Answer:

John need to get 293 in his next game to bring his average up to 183.

Step-by-step explanation:

John starts with N games played and averaging 177 points per game.

In game N+1, John scored 199 points.

\frac{177N + 199}{N+1}=178\\177N+199=178N+178\\N=21\\

So, John has now played (N+1) = 22 games.

We need to know what score John needs in game 23 to bring his average to 183.

\frac{177*21 + 199+Y}{23}=183\\3916+Y=4209\\Y=293\\

A telemarketer earns $150 a week plus $2 for each call that results in sale. Last week she earned a total of $204. How many of h
cluponka [151]

Answer:

27 calls

Step-by-step explanation:

Let T(x) represent total sales.

Then T(x) = $150 + ($2/call)x, where x is the number of calls made.

If T(x)        = $204, we can solve for x, the number of calls made:

$204 = $150 + ($2/call)x, or

 $ 54

----------- = 27 calls

$2/call
