How do u do 5 pounds 4 ounces for $26.88 what’s the cost per ounce

ExtremeBDS [4]

First you have to turn pounds into ounces and its 16 oz for 1 pound.

Now you need to multiply 16 by 5.
16×5=80

Now you add the 4 oz to the 80 oz.
80+4=84

Now you need to divide $26.88 by the 84 oz.
26.88÷84=0.32

Then you finally get $0.32 per 1 oz.

I really hope that helped : )

What is the equation used to find the nth term of the arithmetic sequence: -9, -4 1, 6, 11...

elena-s [515]

Answer:

a^n=-9+(n-1).5

Step-by-step explanation:

Arithmetic sequence=a+(n-1)d

a=-9

n=?

d=+5

Arithmetic sequence=-9+(n-1)5

=-9+5n-5

Collect like terms

-9-5+5n

-14+5n

So the final answer is

an=-9+(n-1).5

A student draws two parabolas both parabolas cross the x axis at (-4,0) and (6,0) the y intercept of the first parabolas is (0,-

faust18 [17]

Answer:

The positive difference between the a values is 0.5

Step-by-step explanation:

we know that

Both parabolas cross the x axis at (-4,0) and (6,0)

so

The general equation is

$y=a(x+4)(x-6)$

<em>Find the value of a in the first parabola</em>

The y-intercept is (0,-12)

so

For $x=0, y=-12$

substitute

$y=a(x+4)(x-6)$

$-12=a(0+4)(0-6)$

$-12=a(-24)$

$a=0.5$

<em>Find the value of a in the second parabola</em>

The y-intercept is (0,-24)

so

For $x=0, y=-24$

substitute

$y=a(x+4)(x-6)$

$-24=a(0+4)(0-6)$

$-24=a(-24)$

$a=1$

<em>Find the positive difference between the a values for the two functions</em>

so

$1-0.5=0.5$

Kindly answer this one. Thank you.

Answer:

See below.

Step-by-step explanation:

I'm assuming these questions are about the Midline Theorem (segment AL joins the midpoints of the non-parallel sides.

♦ The midline's length is the average of the lengths of the top and bottom parallel sides.

$AL=\frac{OR+CE}{2}$

Use this equation and substitute values given in each problem, then solve for the missing information.

1. AL = x, CE = 9, OR = 5

$x=\frac{9+5}{2}=7$

2. AL = <em>m</em> - 4, CE = 15, OR = 17

$m-4=\frac{15+17}{2}=16\\\\m-4=16\\\\\\m=20\\\\AL=20-4=16$

3. OR = y + 5, AL = 15, CE = 18

$15=\frac{(y+5)+18}{2}\\\\15=\frac{y+23}{2}\\\\30=y+23\\\\7=y\\\\OR = 7+5=12$
