Maria told Patrick that her quarter weighs less than what a nickel weighs because 0.2 has fewer digits than .18. How can Patrick

Dimas [21]

If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18

Please answer correctly

Answer:

The answer is 6 and -6

Step-by-step explanation:

The given equation is
$x^2 - kx + 9 = 0 ... (1)$

where a = 1. b = -k, c = a

since the equation (1) has equal roots

$\Rightarrow b^2 - 4ac = 0 \newline\\\Rightarrow (-k)^2 - 4(1)(9) = 0\\ \newline\\\Rightarrow (k)^2 - 36 = 0 \newline\\\Rightarrow k^2 = 36 \newline\\\Rightarrow k = \pm 6$

Hence volume of k = 6, -6

Algebra 1. Question 20. Thank you!

Look at the picture.

The formula of the area of a trapezoid is :

$A_T=\dfrac{base+base}{2}\cdot height$

We have:

$base=12m;\ base=5m;\ height=2\cdot3m=6m$

Substitute: $A_T=\dfrac{12+5}{2}\cdot6=17\cdot3=51\ m^2$

The formula of the area of a circle is :

$A_C=\pi r^2$

We have $r=3m$

Substitute: $A_C=\pi\cdot3^2=9\pi\ m^2$

The area of the shaded portion of trapezoid: $A=A_T-A_C$

Substitute: $A=(51-9\pi)\ m^2\approx(51-9\cdot3.14)\ m^2=22.74\ m^2$
