The area of a triangle is 861 square cm. The length of the base is 82 cm. What is the height of the triangle?

Cerrena [4.2K]

Hi!

The equation to find the area of a triangle is...

(a = area
b = base
h = height)

$a = \frac{1}{2} bh$

Fill in the values that we already have.
$861 = \frac{1}{2}82*h$
Divide both sides by 1/2
$861/ \frac{1}{2} = \frac{1}{2}/ \frac{1}{2}82*h$
1722 = 82*h
Divide both sides by 82.
1722/82 = 82/82*h
21 = h

The answer is B. 21 cm

Hope this helps! :)

A movie theater charges $4.50 for children and $8.00 for adults. On a certain day, 1200 people enter the theater and $8375 is co

Lady bird [3.3K]

Answer:

The number of adults who attended=850

The number of children who attended=350

Step-by-step explanation:

a). Determine first expression

Let the number of each group be as follows;

adults=a

children=c

total number of people=1200

This can be expressed as;

number of people=number of children+number of adults

replacing;

a+c=1200...equation 1

b). Determine the second expression

Let the total cost be expressed as shown;

total cost=(cost per child×number of children)+(cost per adult×number of adults)

where;

total cost=$8,375

cost per child=$4.5

number of children=c

cost per adult=$8

number of adults=a

replacing;

(8×a)+(4.5×c)=1,200

8 a+4.5 c=8,375...equation 2

c). Combine equation 1 and 2 and solve simultaneously

1(8 a+4.5 c=8,375)

4.5(a+c=1,200)=4.5 a+4.5 c=5,400

(8 a-4.5 a)+(4.5 c-4.5 c)=(8,375-5,400)=2,975

3.5 a=2,975

a=2,975/3.5

a=850

replacing the value for a in equation 1

850+c=1200

c=1200-850=350

The number of adults who attended=850

The number of children who attended=350
