Answer:

Step-by-step explanation:

The total surface area of the bite= total surface area of the sphere + total surface area of the rectangular prism

Total surface area of a sphere Ss = 4πr²

r = radius of the sphere = diameter/2

Given diameter of the sphere= 3cm; r = 3/2 cm

Ss = 4π(3/2)²

Ss = 4π*9/4

Ss = 9πcm²

For the rectangular prism

Total surface area Sr = 2WL + 2LH + 2HW

W = width of the prism

L = length of the prism

H = height of the prism

Given W = 4cm, L = 4cm, H = 0.5cm

Sr = 2(4)(4) + 2(4)(0.5) + 2(0.5)(4)

Sr = 32+4+4

Sr = 40cm²

Surface area of the bite = 9π + 40

Surface area of the bite = 68.27cm²

Surface area of the bite = 68cm² (to nearest square of a centimetre)

Answer:At a charity fund raiser , adult tickets were sold for 8$ children each and children’s tickets were sold at 2$ each. write an algebraic expression for the total amount raised from the sale of tickets. At a charity fund raiser , adult tickets were sold for 8$ children each and children’s tickets were sold at 2$ each. write an algebraic expression for the total amount raised from the sale of tickets. How much money was raised if the fundraiser sold 238 adult tickets and 375 children’s tickets?

Step-by-step explanation:

2,654$

Step-by-step explanation:

8a + 2c

8 x 238 = 1,904

2 x 375 = 750

750 + 1,904 = 2,654

2,654$

Which quadratic equation defines the function that has zeros at − 1/12 and 1/4 ?

Cerrena [4.2K]

$\bf \begin{cases}
x=-\frac{1}{2}\implies &x+\frac{1}{2}=0\\\\
x=\frac{1}{4}\implies &x-\frac{1}{4}=0
\end{cases}
\\\\\\
\left( x+\frac{1}{2} \right)\left( x-\frac{1}{4} \right)=\stackrel{y}{0}\implies \stackrel{FOIL}{x^2+\frac{1}{4}x-\frac{1}{8}}=y$
