<h2>Good morning,</h2>

<em><u>__________________</u></em>

<em><u>Answer</u></em>:

a+a+a = 3a.

4b-b = 3b.

3x²+x² = 4x².

<u><em>explanation</em></u>

a+a+a = 3a.

4b-b = b(4 - 1) = b × 3 = 3b.

3x²+x² = x²(3 + 1) = x² × 4 = 4x².

An element with mass 780 grams decays by 17.1% per minute. How much of the element is remaining after 19 minutes to the nearest

Anit [1.1K]

Step 1
Formulate a recursive sequence modeling the number of grams after n minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829

a(n) = 780*[0.829<span>^n]
</span>
for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g

the answer is 22.1 g

Please please help me I need to learn this for my school tmr thank u very much if you do help me !!

Answer:

Step 1 :

Split the figure into 3 parts

part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in

part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in

Part 3 :Rectangle with breadth 2in and length 9in

Step 2 :

find the area of each part

Area of part 1

$\frac{1}{2} * base * height = \frac{1}{2}*15*7 = 52.5in^{2}$

Area of part 2

$length * breadth = 11*8 =88in^{2}$

Area of part 3

$length * breadth = 2*9 =18in^2$

Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
