Find the area of the trapezoid by decomposing it into other shapes. A) 48 cm2 B) 55 cm2 C) 66 cm2 D) 96 cm2

snow_tiger [21]

Answer:

The answer is B.

Step-by-step explanation:

You have to use area of trapezoid formula, A = 1/2×(a+b)×h where a, b are the side lengths and h is height :

$area = \frac{1}{2} \times (a + b) \times h$

$let \: a = 6,b = 16,h = 5$

$area = \frac{1}{2} \times (6 + 16) \times 5$

$area = \frac{1}{2} \times 22 \times 5$

$area = 11 \times 5$

$area = 55 \: {cm}^{2}$

What is the slope of the line whose equation is 5y + 6x - 2 = 0

koban [17]

All you need to do to find the slope here is put it into y = mx + b format.

5y + 6x - 2 = 0

the goal is to get the y alone, so...

5y = 2 - 6x

divide both sides by 5

y = 2/5 - (6/5)x

then, just to be clearer for y = mx + b ...... y = (-6/5)x + (2/5)

the slope should be (-6/5)

A nut mixture of peanuts and pecans at a small fair is $1.00 per pound of peanuts and $2.85 per pound of pecans. Over the entire

CaHeK987 [17]

Answer:

B. (12.0, 85.0) There were 12.0 pounds of peanuts and 85.0 pounds of pecans sold at the fair

Step-by-step explanation:

Subtract the first equation from the second:

1.85n = 157.25

n = 157.25/1.85 = 85 . . . . . divide by the coefficient of n

Only one answer choice has 85 pounds of pecans—the one shown above.
