Find the area of each figure below

Ugo [173]

Answer:

25. $27a^{3}b^{2}$

26. $3\pi x^{3}y$

Step-by-step explanation:

For 25:

$A = \frac{a+b}{2} h$ (area of a trapezoid)

$A=\frac{11a^{2}b+7a^{2}b}{2} *3ab$ (substitute terms)

$= \frac{18a^{2}b}{2}*3ab$ (collect like terms)

$= 9a^{2}b*3ab$ (reduce the fraction by crossing out 2)

$= 27a^{3}b^{2}$ (calculate)

For 26:

$A=\pi r^{2}$ (equation of area of a circle)

$A=\pi (3x^{3} y)^{2}$ (enter the radius)

$= 3\pi x^{3} y$ (communtative property to reorder the terms)

Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthl

leva [86]

Let x be the number of gb used.

Question (1):
Runfast = 10 + 4x
BA&D= 6 + 6x

Question (2):
 10 + 4x = 6 + 6x
2x = 4
x = 2

Both companies will cost the same if you use 2 Gb of data.
BA&D will be cheaper if you use less than 2 Gb of data.
Runfast will be cheaper if you use more than 2 Gb of data.

The lines graphed below are parallel. The slope of the red line is -4/3. What is the slope of the green line?

miss Akunina [59]

I believe the correct answer from the choices listed above is option C. The slope of the green line would be -4/3. Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point. These lines should have equal slopes. Hope this answers the question.
