Answer:

\huge\boxed{c)\ A=104\ m^2}\\\boxed{d)\ A=200\ cm^2}

Step-by-step explanation:

They are the trapezoids. The formula of an area of trapezoid is:

A=\dfrac{b_1+b_2}{2}\cdot h

b_1;\ b_2 - <em>parallel bases</em>

h - <em>height</em>

<em />

<h3>c)</h3>

<em />b_1=16m\\b_2=10m\\h=8m<em />

<em>substitute:</em>

<em />A=\dfrac{16+10}{2}\cdot8=\dfrac{26}{2}\cdot8=13\cdot8=104\ (m^2)<em />

<h3>d)</h3>

<em />b_1=35cm\\b_2=15cm\\h=8cm<em />

<em>substitute</em>

A=\dfrac{35+15}{2}\cdot8=\dfrac{50}{2}\cdot8=25\cdot8=200\ (cm^2)

Given the triangle below, what is the length of the third side, rounded to the nearest whole number?
Leno4ka [110]

Answer:

Step-by-step explanation:

You need the Law of Cosines for this, namely:

x^2=21^2+14^2-2(21)(14)cos58 where x is the missing side.

x^2=441+196-311.5925 and

x^2=325.4075 so

x = 18.0 or just 18

A student raises her grade average from a 75 to a 90. what was the percent of increase in the student's grade average? round you
Leona [35]
Here are some formulas...
percent increase = (new number - original number) / original number...* 100
percent decrease = (original number - new number) / original number...* 100
============
a student raises her grade from a 75 to a 90....since it is going from a smaller number to a larger number, u have an increase
percent increase = (90 - 75) / 70....* 100
                           =   15/70   * 100
                           = 0.2142 * 100
                           = 21.42 rounds to 21.4%  increase
-------------------------
36.50 on sale for 32.12...since it goes from a larger number to a smaller number, u have a decrease
percent decrease = (original number - new number) / original * 100
                             = (36.50 - 32.12) / 32.12...* 100
                             = 4.38 / 32.12...* 100
                             = 0.1363...* 100
                             = 13.63 rounds to 13.6% decrease
------------------------------
23.5 to 21.2......this is a decrease
percent decrease = (original number - new number) / original...* 100
                            = (23.5 - 21.2) / 23.5....* 100
                            = 2.3 / 23.5....* 100
                            = 0.0979 * 100
                            = 9.79 rounds to 9.8% decrease
