Laura estimated the total cost of attending a private four-year university using the information in the table. Category Estimate
4vir4ik [10]

Answer:

$124,400

Step-by-step explanation:

The scholarship pays for 30% of her tuition.  This leaves her responsible for 100-30 = 70% of it.  70% = 70/100 = 0.7; this makes her part of the yearly tuition

0.7(29500) = 20650

She is still responsible for her $9600 room and board per year.  Her books are paid for by the scholarship; however she still has the lab and facility fees at $850 per year.

Altogether this gives her a total of

20650+9600+850 = 31100 per year.  Over the course of 4 years, this will cost her

31100(4) = 124400

How do you do this? please help me
Anastaziya [24]

Answer:

f = 10, g = 4.8 cm

Step-by-step explanation:

Area of ABCE = 60 cm²

Area of ABCD = 48 cm²

So,

Area of ADE = 60-48

=> 12 cm²

Area of ADE = \frac{1}{2} (Base)(Height)

<u><em>Where Area = 12 cm², Base = 4 cm</em></u>

12 = \frac{1}{2}(4)(Height)

Height = 12-2

Height = 10 cm

Where Height is AD

So, AD = 10 cm

Also, <u><em>AD is parallel and equal to BC</em></u>(f)<u><em></em></u>

So,

f = 10 cm

<u><em>Now, Finding g</em></u>

Area of ABCD = Base * Height

<u><em>Where Area = 48 cm², Base = 10 cm</em></u>

48 = 10 * Height

Height = 48/10

Height = 4.8 cm

Whereas, Height is g

So, g = 4.8 cm
