Jared sells square frames of various sizes made of wood. To find the area of a frame, Jared uses the formula A = s^2 - (s - 2w)^2, where s is the length of a side of the frame and w is the width of the frame.

Part B.) Find the area of a frame that measures 20 inches on each side and has a width of 3 inches

Part C.) Jared charges 18 cents per square inch for his frames. How much will he charge for a frame that measures 16 inches on each side and has a width of 2 inches?

Answers

A= 20 times 20 - (20 - 2 times 3) times (20-2 times 3) this equal 336

Answer:

B.204 square inches

C.2016 cents

Step-by-step explanation:

We are given that Jared sells square frames of various sizes made of wood .To find the area of a frame ,Jared uses the formula

[tex]A=s^2-(s-2w)^2[/tex]

Where s=Length of a side of the frame

w=Width of the frame

B.We are given that length of each side=s=20 inches

Width of frame=w=3 inches

Substitute the values in the above given   formula

Then, we get

A=[tex](20)^2-(20-2\times 3)^2[/tex]

[tex]A=400-(20-6)^2[/tex]

[tex]A=400-196=204 [/tex]square inches

Hence, area of frame=204 square inches

C.We are given that

Cost of 1 square inch=18 cents

Length of each side of frame=s=16 inches

Width of frame=w=2 inches

Substitute the values in the given above formula

Then ,we get [tex]A=(16)^2-(16-2\times 2)^2[/tex]

[tex]A=256-(12)^2[/tex]

[tex]A=256-144=112[/tex] square inches

Cost of 112 square inches=[tex]112\times18[/tex]=2016 cents

Hence, he will charge for a frame =2016 cents

The rectangle below has an area of x^2-144 square meters and a length of x+12 meters. What expression represents the width of the rectangle?

Answers

Since length*width=area, (x+12)*width=x²-144. Dividing (x+12) from both sides, we get (x²-144)/(x+12)=width. One formula we can use is that
(a²-b²)=(a-b)*(a+b). Since 144=12², that means that x²-144=(x-12)*(x+12). Plugging that in, we get (x-12)*(x+12)/(x+12)=(x-12)=width

The expression for the width of the rectangle is W = ( x - 12 )

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

We can use the formula for the area of a rectangle to find an expression for its width:

Area = length × width

The length of the rectangle is given as x + 12 meters, and the area is given as x² - 144 square meters.

We can substitute these values into the formula and solve for the width:

x² - 144 = (x + 12) × width

To solve for the width, we can divide both sides of the equation by x + 12:

width , W = (x² - 144) / (x + 12)

W = ( x + 12 ) ( x - 12 ) / ( x + 12 )

W = ( x - 12 )

Hence , the expression that represents the width of the rectangle is given by W = (x² - 144) / (x + 12) = ( x - 12 )

Help pls.. urgent!

Answers

Alright, so 3f-g=4 and f+2g=5. 
3f-g=4
f+2g=5
Multiplying the first equation by 2 and adding it to the second, we get 7f=13 and by dividing both sides by 7 we get f=13/7. Since f+2g=5, then we can plug 13/7 in for f to get 13/7+2g=5. Next, we subtract 13/7 from both sides to get 2g=3+1/7=22/7 (since 3*7=21 and 21+1=22). DIviding both sides by 2, we get 22/14=g. Plugging that into f/39g, we get (13/7)/(22*39/14)
= (13/7)/(858/14) 
= (13/7)*(14/858)
=182/6006
= 91/3003 (by dividing both numbers by 2)
= 13/429 (by dividing both numbers by 7)
 = 1/33 (by dividing both numbers by 13)

could negative 2 be used as a base to rewrite 32 and 64 why or why not

Answers

Alright, finding the powers of -2, we get 4, -8, 16, -32, and 64. For the powers of 2, we get 4,8,16,32, and 64. Notice that for the even powers of both, they're the same, but the odd powers are different, such as 2^5=32 and -2^5=-32. The same applies for 64, but since it's to the power of 6 (even) they're the same

You have a stack of pennies without counting the pennies, how can you know if there is a odd or even number of them

Answers

You can put the pennies in 2 rows, if they match then they are even, if not they are odd

Suppose that you have a stack of pennies. If you want to know without counting whether there is an odd or even number of pennies, then you have to split them into two parts, for example,  placing one coin left and one coin  right.

If the number of pennies is even, then no coins will left, if the number is odd, then one coin will be extra.

The thickness of a surfboard relates to the weight of the surfer. A surfboard is 21/3/16 inches wide and 2/3/8 inches thick. Write each dimension as a decimal.

Answers

Minus 21/3/16 with 2/3/8

Answer: Each dimension would be 21.1875 inches and 2.375 inches respectively.

Step-by-step explanation:

Since we have given that

Width of a surfboard = [tex]21\dfrac{3}{16}\ inches[/tex]

Thickness of a surfboard = [tex]2\dfrac{3}{8}\ inches[/tex]

We need to rewrite each dimension as a decimal.

We first write it in improper fraction:

Width becomes

[tex]21\dfrac{3}{16}\\\\=\dfrac{339}{16}\ inches[/tex]

Thickness becomes

[tex]2\dfrac{3}{8}\\\\=\dfrac{19}{8}\ inches[/tex]

Now, we change it into decimal form:

[tex]\dfrac{339}{16}=21.1875\ inches\\\\and\\\\\dfrac{19}{8}=2.375\ inches[/tex]

Hence, each dimension would be 21.1875 inches and 2.375 inches respectively.

i think it would be f but if you wsnt to check i have a really good calculator that can give tou the answer
The answer for this one is F. I'm 100% sure it's F because T is wrong, the answer can't be all positive numbers. S is wrong because if you distribute the negative sign from -(2.1-5.9), you will get -2.1+5.9, which is not the same as the original expression. U is also wrong because the first one, or the binomial (2.1+5.9), suppose to be negative, not positive. F is the correct answer.

Which umber is greater? Square root of 220 or 14 3/4?

Answers

Square root is 220 the number is way bigger than 14 3/4

The number square root of 220 is greater than that of 14 3/4.

Given are two numbers.

The square root of 220 and 14 3/4.

We have to find which number is greater.

We know that :

14 3/4 = 14 + 3/4 = 14.75

Now,

14² = 196

15² = 225

So the number 220 lies between 196 and 225.

So √220 lies between 14 and 15.

Since 220 is closest to 225 which is the square of 15, the square root os 220 is more close to 15.

√220 ≈ 14.8

Hence √220 is greater.
