What is the surface area of the rectangular prism?

Answers

Answer:

348 in.² is the answer.

Step-by-step explanation:

To find our answer we will multiply each number by each other.

6 x 8 = 48

6 x 9 = 54

8 x 9 = 72

Now we have our numbers 48, 54, and 72, we will multiply each one by 2.  

48 x 2 = 96

54 x 2 = 108

72 x 2 = 144

For our final step we will add all these together to find our surface area.  96 + 108 + 144 = 348.  Therefore, 248 in² is our answer.

Answer:

She shaded area?

12 x 10 = 120

6 x 7 = 42

42 divided by 2 = 21

Now we subtract both areas:

120 - 21 = 99 of the shaded region.

Answer:

99

Step-by-step explanation:

7 * 6 is 42 then divide by 2 = 21

12 * 10 is 120

Answers

Complete question :

A grocery store charges $4.50 per pound for organic apples. What is the cost c, in dollars, of p pounds of organic apples? Write an equation to represent the situation.

Answer:

c =4.50p

Step-by-step explanation:

If cost of apples in dollars = c

Weight of apples in pounds = p

The charge in dollar per pound of apple = $4.50

The total cost, c of apple can be expressed as :

Total cost, c = charge per pound * weigh of apple

Total cost, c = $4.50 * p

c = 4.50p

#Captainpower

Answer:

21

Step-by-step explanation:

Kindly check the image below to see a visual of how the question is set up.

( my apologies for the terrible handwriting lol )

Now lets look back at the question.

The question is asking us to find the total length of Jayleen and Walter's entire walk.  

Essentially it's asking for the perimeter.

In order to find the perimeter we must find the length of the hypotenuse.

Notice that the image created forms a triangle with a right angle.

That being said we can use the Pythagorean Theorem to solve for the missing side length ( or the "shortcut" ) ( also note that the Pythagorean theorem only works with right triangles )

The Pythagorean theorem = [tex]a^2+b^2=c^2[/tex] where a and b = legs and c = hypotenuse

The two legs = 5 and 7 and the hypotenuse = the shortcut

That being said, we plug in the given values ( a and b ) and solve for "c"

[tex]5^2+7^2=c^2[/tex]

step 1: Simplify

[tex]5^2=25\\7^2=49\\25+49=74[/tex]

now we have 74 = c²

step 2 take the square root of each side

[tex]\sqrt{74} =8.60232\\\sqrt{c^2} =c[/tex]

we're left with c = 8.60232

This means that the shortcut that Jayleen and Walter took had a distance of 8.6

Finally we find the perimeter of the triangle

Perimeter = sum of side lengths

8.6 + 7 + 5 = 20.6

* round to the nearest whole number *

The answer would be 21

To find 'w', simply divide the answer by the coefficient.

[tex]3.84/3=1.28[/tex]

[tex]w=1.28[/tex]

REMEMBER: ANYTIME YOU SEE A COEFFICIENT AND A VARIABLE, YOU MUST MULTIPLY THE COEFFICIENT AND THE VARIABLE.

We can check our answer by multiplying.

[tex]3*1.28 = 3.84[/tex].

Therefore, w = 1.28.

Step-by-step explanation:

Sine: Opposite side over hypotenuse

Cosine: Adjacent side over hypotenuse

Tangent: Opposite side over adjacent side

Respective to angle O, we are given the adjacent side, 5, and the hypotenuse 14, so we can use cosine.

cos(O)=5/14

O=arcsin(5/14)≈69.0752
