At the local grocery store, a 16-ounce bottle of apple juice costs $3.20. What is the cost of the apple juice per ounce? Show wo

oee [108]

<u>The answer is $0.20</u>

<u>When you say 3.20 ÷ 16, it gives you 0.2, but you need to add a zero at the end to make it understandable, so that is how you end up with $0.20</u>

Answer:

12.566

Step-by-step explanation:

A = ∫1/2(r)^2dtheta from a - b = 0 to 2π

∫1/2(sin^2theta-4sintheta+4)dtheta

[9/4theta+2costheta-1/8sin2theta] from 0 to 2π…

when you solve this you get 14.137 without taking out the cos(2theta+3)

The question is on the attached image :)

olga_2 [115]

The mean can be found by adding the two numbers and dividing by 2

let the second number be y

(x + y)/2 = 1/2x + 1

solve for y

multiply each side by 2
x + y = 2(1/2x + 1)
distribute
x + y = x + 2
subtract x on both sides
y = 2

ANSWER: the second number is 2

Write that down the equation for the lines that is the graphs are depicted below

erastovalidia [21]

A(1,2)

Find slope of line (m)

$\\ \sf\longmapsto m=\dfrac{2-0}{1-0}$

$\\ \sf\longmapsto m=2$

Putting in y=mx+b

$\\ \sf\longmapsto y=mx+b$

$\\ \sf\longmapsto 2=2(1)+b$

$\\ \sf\longmapsto 2=2+b$

$\\ \sf\longmapsto b=2-2=0$

Equation of the line

$\\ \sf\longmapsto y=2x$

I cant believe how bad my brother, Reuben, is at growing things. He bought a whole bunch of plants at the nursery the other day.

jeka94

Answer:

68 plants.

Step-by-step explanation:

Let x represent the number of plants that Reuben bought from the nursery.

We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be $x-5$ .

We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be $\frac{2}{9}(x-5)$ .

Further a rabbit came and ate ½ of what was left. So number of plants left would be $\frac{\frac{2}{9}(x-5)}{2}=\frac{2}{9\times 2}(x-5)=\frac{1}{9}(x-5)$ .
