Which is a better buy, 5 for $4.25 or 8 for $6.88?

Given :

Base area of Ms. Jones decorative pyramid = 6 inches²

Height of the decorative pyramid = 15 inches

We know that :

[tex]\color{hotpink}\tt \: volume \: of \: a \: triangular \: pyramid\color{plum} \tt \: = \frac{1}{3}Bh [/tex]

Volume of the decorative pyramid :

[tex] =\tt \frac{1}{3} \times 15 \times 6[/tex]

[tex] =\tt \frac{15 \times 6}{3} [/tex]

[tex] =\tt \frac{90}{3} [/tex]

[tex]\color{plum} =\tt 30 \: {inches}^{3} [/tex]

Therefore, the volume of the decorative pyramid with Ms. Jones = 30 inches³

====================================================

Explanation:

We replace every copy of x with 5. Then we apply the order of operations PEMDAS to simplify.

f(x) = -2x+1

f(5) = -2(5)+1 ..... x replaced with 5

f(5) = -10+1

f(5) = -9

A ratio shows us the number of times a number contains another number. The width of the frame after enlargement is 5 inches.

A ratio shows us the number of times a number contains another number.

Given that the frame is 1 inch wide and 4 inches tall. Now, if the frame is enlarged, then the ratio of the corresponding sides will be equal.

Further, given that height after enlargement is 20 inches. Therefore, if the ratio of the height of the before enlargement and after enlargement is taken, then it will be,

Ratio = After Enlargement/ Before Enlargement

Ratio = 20 inches / 4 inches

Ratio = 5

Now, if we use the ratio to find the width of the frame after enlargement, then the frame width will be,

Ratio = After Enlargement/ Before Enlargement

5 = Width after Enlargement/ Width before Enlargement

5 = Width after Enlargement/ 1 inche

Width after Enlargement = 5 inches

Hence, the width of the frame after enlargement is 5 inches.

Answer:

g(f(5)) = 6

Step-by-step explanation:

Obtain f(5) from the graph of y = f(x)

Locate x = 5 on the x- axis, go vertically up to meet the graph at (5, 4 )

Now evaluate g(4) from the graph of y = g(x)

Locate x = 4 0n the x- axis, go vertically up to meet the graph at (4, 6 )

Then the value of g(f(5)) = 6

x = 1 and x = -3

Step-by-step explanation:

We need to solve the given equation.

[tex]3+x=x^2+3x[/tex]

Taking all terms together,

[tex]x^2+3x-3-x=0\\\\x^2+2x-3=0\\\\x^2+3x-x-3=0\\\\x(x+3)-1(x+3)=0\\\\(x-1)(x+3)=0\\\\x=1\ and\ x=-3[/tex]

So, the solution of the above equation is x = 1 and x = -3.

Answer:

[tex] y = \dfrac{w}{h - 5t^2} [/tex]

Step-by-step explanation:

w = yh − 5yt^2

There is a y in each term on the right side. We factor it out.

w = y(h - 5t^2)

Now we divide both sides by h - 5t^2 to isolate y.

[tex] \dfrac{w}{h - 5t^2} = y [/tex]

[tex] y = \dfrac{w}{h - 5t^2} [/tex]
