What is the area in square centimeters in trapezoide

1 answer:

7 0

$\bf \textit{area of a trapezoid}\\\\
A=\cfrac{h(a+b)}{2}~~
\begin{cases}
a,b=\stackrel{bases}{parallel~sides}\\
h=height\\
---------\\
a=8.6\\
b=12.9\\
h=6.4
\end{cases}\implies A=\cfrac{6.4(8.6+12.9)}{2}
\\\\\\
A=\cfrac{6.4(21.5)}{2}$

Quarters ≡ Dimes ≡ Nickels ≡ Pennies

23 ≡ 29 ≡ 17 ≡ 38

Answer:

$P(Q\ or\ P) = 0.5701$

Step-by-step explanation:

Given

$Quarters = 23$

$Dimes = 29$

$Nickels = 17$

$Pennies = 38$

First, we calculate total number of coins

$Total = 23 + 29 + 17 + 38$

$Total = 107$

The probability of obtaining quarter (Q) of penny (P) is:

$P(Q\ or\ P) = P(Quarters) + P(Pennies)$

$P(Q\ or\ P) = \frac{n(Quarters)}{Total} + \frac{n(Pennies)}{Total}$

Take LCM

$P(Q\ or\ P) = \frac{n(Quarters) + n(Pennies)}{Total}$

$P(Q\ or\ P) = \frac{23 + 38}{107}$

$P(Q\ or\ P) = \frac{61}{107}$

$P(Q\ or\ P) = 0.5701$
