Answer:
20 oz for $0.60
Step-by-step explanation:
You can determine the least-cost item by comparing costs at the same size. (This can be done using mental arithmetic.)
68 ounces is between 3 and 4 times the size of 20 ounces. If the costs were the same, 68 ounces would cost between 3·$60 = $1.80 and 4·$60 = $2.40. The cost of 68 ounces is closer to $2.40 than 68 is to 80, so we conclude the 20-ounce soda costs less.
The cost of 100 ounces at the 20-ounce price would be 5·$0.60 = $3.00, which is less than the cost of the 100-ounce soda. Again, the 20-ounce soda is cheaper.
The least cost per ounce is the 20-ounce soda.
__
If you like, you can actually find the cost per ounce by dividing the cost by the ounces. Those results are shown in the attached table. The 20-ounce soda costs the least.

A Petri dish is growing bacteria. It starts with 3 cells on day 1, 9 cells on day 2, and continues tripling the number of cells every day after that. How many cells of bacteria are there on day 5? 3 5 5 3 15 18
Answer:
243
Step-by-step explanation:
Given that:
Day 1 = 3
Day 2 = 9
After the 2nd day, number of cells continue to triple ;
Day 3 = 9^3
P(t) = 9 * 3^3
P(t) = 9 * 27
= 243
What are all the variables of x y and z ?
Answer:
x°=96°
y°=88°
z°=151°
Step-by-step explanation:
55°+29°+×°=180°
×°=96°
96°+55°=z°
z°=151
then let variable A° be one of the inner angle of the triangle
A°+z°=180°
A°+151°=180°
A°=29°
finally adding all the inner angles will give us 180°
96°+y°-13°+29=180°
y°=88°

Answer: B)-4
Step-by-step explanation:
The given equation: [tex]\dfrac{6}{x^2-9}-\dfrac{1}{x-3}=1[/tex]
Using identity: [tex]a^2-b^2=(a-b)(a+b)[/tex]
[tex]\dfrac{6}{(x-3)(x+3)}-\dfrac{1}{x-3}=1\\\\\Rightarrow\ \dfrac{6-(x+3)}{(x-3)(x+3)}=1\\\\\Rightarrow\ \dfrac{6-x-3}{(x-3)(x+3)}=1\\\\\Rightarrow\ 3-x=(x-3)(x+3)\\\\\Rightarrow\ (-1)(x-3)=(x-3)(x+3)\\\\\Rightarrow\ -1=x+3\\\\\Rightarrow\ x=-1-3=-4 \ \ \ [x\neq3][/tex]
Hence, the solution is : x=-4
The correct option is B.

The applicable rules of exponents are ...
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)

Answer:
Evaluating the piecewise function when X =3, we get f(3) = 7
Step-by-step explanation:
Given the following piecewise function
f(x)= { 2x+1; where x > 0
-3 when x ≤ 0
Evaluate the function when X = 3
We will evaluate f(x) =2x+1 where x > 0, because x = 3 and 3 <0
We can't use -3, because x ≤ 0, and 3 is not less than 0.
Now, evaluating the function:
[tex]f(x)=2x+1\\Put\:x=3\\f(3)=2(3)+1\\f(3)=6+1\\f(3)=7[/tex]
So, Evaluating the piecewise function when X =3, we get f(3) = 7

chloe is 5 feet 4 inches tall. there are 2.54 centimeters in 1 inch. what is chloe's height in centimeters?
Answer:
Her height would be 162.56 centimeters tall.
Step-by-step explanation:
There are 12 inches in 1 foot so that would mean that 1 foot has 30. 48 centimeters.
30.48 x 5 = 152.4
Add the 4 extra inches so 4 inches in centimeters is 10.16
152.4 + 10.16 = 162.56

Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of .5 m/s2. What is her final velocity?
If Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s². then 12.25 m/s is the final velocity.
What is Velocity?Velocity is the distance covered by an object in unit time.
Given that,
Summer (starting from rest) runs from the 20 m mark to the 35 m mark with an acceleration of 5 m/s²
a=0.5 m/s²
s is distance=35-20=15
We have a formula with velocity, acceleration and distance
Now v²=2as
Here v is velocity=2
a is acceleration=5
s is the distance.=15
v²=2×5×15
The multiplication value of 2×5×15 is 150.
v²=150
Take square root on both sides
v=√150
v=12.25 m/s
Therefore final velocity is 12.25m/s.

When an account balance increases it means that it has been credited and when it decreases, it has been debited.
The beginning balance here is $0 and the closing balance is $15.
There were 2 transactions, one credit and one debit.
For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.
Scientists are drilling a hole in the ocean floor to learn more about the Earth's history Currently, the hole is in
the shape of a cylinder whose volume is approximately 4200 cubic feet and whose height is 4.3 miles. Find
the radius of the hole to the nearest hundredth of a foot. (Hint: Make sure the same units of measurement are
used.)
The radius of the hole is
feet. (Round to the nearest hundredth.)
Answer:
The radius of the hole is 0.24 feet
Step-by-step explanation:
Firstly, we need to convert the miles to feet
Mathematically;
1 mile = 5,280 feet
4.3 miles is thus;
4.3 * 5,280 = 22,704 feet
Mathematically, the volume of a cylinder is;
V = pi * r^2 * h
here, we want to get r
4200 = 3.142 * r^2 * 22,704
r^2 = 4200/(3.142 * 22,704)
r = 0.24 feet

Your kite is stuck in a tree that is 40 feet tall. The angle your string makes with the ground is 72°. Rather than worrying about the kite, you decide to calculate how much string you have let out. Assuming the string is held tight and makes a straight line to the ground, how much string have you let out?
Answer:
42 feet of string
Step-by-step explanation:
First, draw a diagram of the string, the height and the angle.
the length of the string is equal to the hypotenuse of the triangle
let length of the string=x
sin(θ)=opp/hyp
sin(72°)=40ft/x
x=40ft/sin(72°)
x=42.05848897ft≈42ft
