Answer:

C) 1/2(15 +23)(9)

Step-by-step explanation:

The formula for the area of a trapezoid in terms of base lengths b1 and b2 and height h is ...

... A = 1/2(b1 +b2)h

Substituting the values shown in the figure, this becomes ...

... A = 1/2(15 +23)(9) . . . . . matches selection C

Answer:

Highest Elevation: 14240

Lowest Elevation: -285

Step-by-step explanation:

Given

$Highest\ Elevation = 14,240\ ft$ above sea level

$Lowest\ Elevation = 285\ ft$ below sea level

Required

Represent both altitudes as an integer

For the Mountain:

Take the sea level as 0 feet

$Altitude = Highest\ Elevation - Sea\ Level$

$Altitude = 14240 - 0$

$Altitude = 14240$

Hence, the integer is 14240

For the Valley:

Take the sea level as 0 feet

$Altitude = Sea\ Level - Lowest\ Elevation$

$Altitude = 0 - 285$

$Altitude = -285$

Hence, the integer is -285

Pen are shipped to the office supply store in boxes of 12 each. Write a function rule to calculate the total number of pens when

Tom [10]

p = 12x is the function rule to calculate the total number of pens when you know the number of boxes

Solution:

Given that,

Pen are shipped to the office supply store in boxes of 12 each

To find: Write a function rule to calculate the total number of pens when you know the number of boxes

Let "p" be the total number of pens

Let "x" be the number of boxes

Number of pens in each box = 12

Then from given information,

Total number of pens = Number of boxes multiplied by number of pens in each box

$p = x \times 12\\\\p = 12x$

Thus the function rule is found
