Answer:

$384\ in^{2} \\$

Step-by-step explanation:

Hello

according to the graph the figure is a cube, which has 6 square faces of 8 inches each side,the total area will be equal to the area of one of these faces multiplied by 6

Area of a square=side* side

Area of square= 8 in * 8 in

$Area = 64\ in^{2} \\$

Now, the total area is

$Tarea=6*64\ in^{2} \\Tarea=384\ in^{2}$

1 in= 1 inch = 2.54 cm

have a fantastic day

vazorg [7]

Answer:

$They'll \: be \: on \: the \: circle:$

$(x+3)^2+(y+6)^2=25$

$x=1$

$(y+6)^2=9$

$y + 6 = 3$

$y = -3$

$(1,-3)$

$y + 6 = -3$

$y = -9$

$(1,-9)$

peter buys 12 bunches of bannas for 9.00. use a ratio table to determine how much peter will pay for 8 bunches.

erik [133]

We are given that Peter buys 12 bunches of bananas for 9.00.

We need to determine how much peter will pay for 8 bunches.

Let us set up proportion now.

12 bunches of bananas for 9.00 = 12 : 9

Let us assume Peter will pay for 8 bunches = $x.

Therefore, 8 bunches of bananas for x = 8 : x.

<h3>Setting up proportion:</h3><h3> $\frac{12}{9} = \frac{8}{x}$ </h3>

On cross-multiplying, we get

12x = 9×8

12x = 72.

Dividing both sides by 12, we get

$\frac{12x}{12} =\frac{72}{12}$

x=6.

<h3>Therefore, Peter will pay $6 for 8 bunches.</h3>

50 POINTS!!!!! HELP Soybean meal is 16% protein; cornmeal is 8% protein.How many pounds of each should be mixed together in orde

tia_tia [17]

The first thing we are going to do for this case is define variables.
We have then:
x: Amount of soybean meal
320 - x: quantity of cornmeal
We now write the equation that models the problem:
$0.16x + 0.08 (320-x) = 0.09 (320)
$
Rewriting we have:
$0.16x + 25.6 - 0.08x = 28.8
$
From here, we clear x:
$0.16x - 0.08x = 28.8 - 25.6

0.08x = 3.2

x = 3.2 / 0.08

x = 40$
Then, the amount of Soybean meal is:
$x = 40 lb
$
The amount of cornmeal is:
$320 - x = 320 - 40 = 280 lb
$
Answer:
cornmeal: 280 lb
Soybean: 40 lb.
