Answer:

$64.8

Step-by-step explanation:

To determine the tax, you want to make the percent into a decimal by moving the decimal point over two times the the left, which means 8% would be 0.08. Then, multiply the new decimal by the price. 60 times 0.08 is 4.8. Now, add the tax to the original price. 60+4.8=64.8, so therefore the total cost is $64.8

7. Use the discriminant to determine how many real number solutions exist for the quadratic equation –4j2 + 3j – 28 = 0.

GrogVix [38]

$\bf \begin{array}{llccll}
y=&{{ -4}}j^2&{{ +3}}j&{{ -28}}\\
&~\uparrow &\uparrow &\uparrow \\
&~a&b&c
\end{array}
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}$

so.. check what value the discriminant is then.

A right rectangular prism has a volume of 470.40 cm³. The length of the solid is 6.4 cm and the width is 9.8 cm. What is the hei

andrezito [222]

If a rectangular prism has a volume of 470.40 cm³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height

Length x Width x Height = Volume
6.4 cm • 9.8 cm `• h = 470.40

470.40 ÷ (9.8 x 6.4)
 = 470.40 ÷ 62.72
 = 7.5

Check Answer:
Length x Width x Height = Volume
6.4 cm • 9.8 cm `• 7.5 = 470.40

Answer: 7.5 cm

Answer:

For question 3, the slope would be -5

Step-by-step explanation:

If you wanted to graph this you would have to plot one of the points that is already given. Then from that point, you would move 5 units down and 1 unit to the right. If you run out of space, you can go to the other direction by going 5 units up and 1 to the left.

Hope this helps :)
