Answer:

  = 30mn^4

Step-by-step explanation:

The area of a trapezoid

A = 1/2 (a+b) *h

where a and b are the top and bottom

A = 1/2( 3mn^2+ 9mn^2) * 5n^2

Combine like terms

A = 1/2(12mn^2) * 5n^2

  =6mn^2 * 5n^2

  = 30mn^4

A high school has a total of 850 students. there are 60 more female students than there are make students?
Mrac [35]
Hey. Let me help you on this one.

Let's break this problem down so it's easier for us to comprehend it.

There are 850 students in the school, and the amount of female students equals to the amount of male students + sixty additional females.

Amount of students in school = 850 students

Male students = X

Female students = X+60

Let's form an equation so we can work with what we have.

X+(X+60)=850

Subtract 60 from both sides.

X+X=790

Simplify

2X=790

Divide both sides by 2.

X=395

Answer: There are 395 male students, and 455 female students.

Lisa [10]

Answer:

12 inches

Step-by-step explanation:

Given

\theta = 31^{\circ}

diagonal = 23.3\ in

Required

Determine the height of the canvas

The question is illustrated using the attached image.

Using the attachment as a point of reference, the height is calculated from

sin \theta = \frac{opp}{hyp}

This gives:

sin 31^{\circ}= \frac{h}{23.3}

Make h the subject

h = 23.3 * sin(31^{\circ)

h = 23.3 * 0.5150\\

h = 11.9995

h = 12\ inches
