Laura delivers newspapers. She spent 4|12 of her savings one new CD. Which equivalent fraction shows the amount Laura spent?

julia-pushkina [17]

Equivalent fractions are fractions that have the same value. They can be found by reducing the fraction or by multiplying both the numerator and denominator by the same number.

In this case, 4 and 12 can both be divided by 4, so the fraction 4/12 can be reduced to 1/3.

Answer:

y = $\frac{3}{2} x+6$

Step-by-step explanation:

3x-2y=-12

-2y=-3x-12

y = (-3x-12)/-2

y = $\frac{3}{2} x+6$

Find the volume of a pyramid with a square base, where the perimeter of the base is 5\text{ in}5 in and the height of the pyrami

Nana76 [90]

Answer:

Volume = 1.9 in3

Step-by-step explanation:

If the perimeter of the square base is 5 inches, we have that:

Perimeter = 4 * side

5 = 4 * side

side = 1.25 in

Then, to find the volume of the pyramid, we can use the formula:

Volume = (1/3) * side^2 * height

So we have that:

Volume = (1/3) * 1.25^2 * 3.6

Volume = 1.875 in3

Rounding to nearest tenth, we have Volume = 1.9 in3

Define an exponential function, h(x), which passes through the points (1,16) and(5, 1296). Enter your answer in the form axb^xh(

Lerok [7]

Define an exponential function, h(x), which passes through the points (1,16) and

(5, 1296). Enter your answer in the form axb^x

the equation is of the form

$y=a(b)^x$

we have

point (1,16)

so

For x=1, y=16

substitute

$\begin{gathered} 16=a(b)^1 \\ 16=a\cdot b \end{gathered}$

isolate the variable a

$a=\frac{16}{b}$

Point (5,1296)

For x=5, y=1,296

substitute

$1,296=a(b)^5$

substitute equation 1 in equation 2

$1,296=(\frac{16}{b})\cdot b^5$

solve for b

$\begin{gathered} \frac{1296}{16}=b^4 \\ b^4=81 \\ b=3 \end{gathered}$

Find the value of a

a=16/3

therefore

the equation is

$y=\frac{16}{3}\cdot(3)^x$

see the attached figure to better understand the problem
