It is a tool as it represents the language of patterns.

It is also a means of working with abstract notions and then applying them, which frequently leads to the formation of generalisations and insights outside of the original context.

Answer:

$114.8\ ft^{2}$

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

$A=\frac{1}{2}(b1+b2)h$

In this problem we have

$b1=12\ ft$

$b2=15\ ft$

$h=8.5\ ft$ ----> the height of the trapezoid is the perpendicular distance between the bases

substitute the values

$A=\frac{1}{2}(12+15)(8.5)$

$A=\frac{1}{2}(27)(8.5)=114.75\ ft^{2}$

Round to the nearest tenth

$114.75=114.8\ ft^{2}$

If you simply want to multiply the answers given to you I would say answer c. 6lbs peanuts, 3 pound almonds and 2lb raisins. If you multiply 6*1.50 you get 9, you multiply 3*3.00 would also equal 9, and 2*1.50 is 3. 9+9+3=21

What’s the answer to 14?

Answer:

|t -(-5)| = 1.5
[-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

|t -(-5)| = 1.5

This is equivalent to two equations:

t +5 = -1.5
t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

t = -6.5 . . . . minimum allowed temperature
t = -3.5 . . . . maximum allowed temperature
