Answer:

As what you described, you have done quite well.

Until last step, there would need a simplification of 6/45.

$\frac{6}{45} = \frac{2*3}{15*3} = \frac{2}{15}$

=> Option B is correct.

Hope it helps!

Area of the right triangle prism = ½*a*c*h

a = 91 yd

c = 60 yd

h = 45 yd

Volume = ½*91*60*45

= 122,850 yd³

4xsquared - 9=0? could anyone help me solve this quadratic equation by FACTORING?

Verizon [17]

$\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
4x^2-9=0\implies 2^2x^2-3^2=0\implies (2x)^2-3^2=0
\\\\\\\
[(2x)-3][(2x)+3]=0\implies 
\begin{cases}
2x-3=0\\
2x=3\\
x=\frac{3}{2}\\
------\\
2x+3=0\\
2x=-3\\
x=-\frac{3}{2}
\end{cases}$

For the last three days, it has rained 0.13 inches, 0.08 inches, and 0.18 inches. What is the best estimate of the total rainfal

Natali [406]

Answer:

(D) . The best estimate of the total rainfall is 0.4 inches.

Step-by-step explanation:

Here, as given in the data:

The rainfall on the first day = 0.13 inches

Now, the 'nearest tenth' estimation of 0.13 = 0.10 as ( 3 < 5)

So, the estimated rainfall on first day = 0.10 inches

The rainfall on the second day = 0.08 inches

Now, the 'nearest tenth' estimation of 0.08 = 0.10 as ( 8 > 5)

So, the estimated rainfall on second day = 0.10 inches

The rainfall on the third day = 0.18 inches

Now, the 'nearest tenth' estimation of 0.18 = 0.20 as ( 8 > 5)

So, the estimated rainfall on third day =0.20 inches

So, total estimated rainfall = Estimated rainfall on ( first + second + third day)

= 0.10 inches + 0.10 inches + 0.20 inches

= 0.40 inches

Hence, the best estimate of the total rainfall is 0.4 inches.
