The price for 3 pounds of apples is $3.99. What is the unit rate?
Answer:
the unit rate is 1.33$ per pound of apples
Step-by-step explanation:
you can rewrite the word problem as
3x = 3.99.
now just divide both sides by 3.
3x / 3 = 3.99/3
x = 1.33

Simplify the expressions below by using the rules of exponents. A.2^4 B.3^0 C.4^6∙4^(-3) D.(2^3 )^2 Answer:
Answer:
The three rules that we have are:
[tex]x^a*x^b = x^{a + b}[/tex]
[tex]\frac{x^a}{x^b} = x^{a - b}[/tex]
[tex](x^a)^b = x^{a*b}[/tex]
Then let's solve the problems:
A) 2^4 = 2^(2*2) = (2^2)^2 = 4^2 = 16.
B) 3^0 = 3^(a - a) = 3^a/3^a = 1. (for any real number a)
From this we can conclude that the power 0 of any number is equal to 1.
C) 4^6*4^(-3) = 4^(6 - 3) = 4^3 = 64
D) (2^3)^2 = 2^(3*2) = 2^6 = 64

The required simplified value of the given expression is x = 1/3.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression is an exponential expression,
Though,
8ˣ = 2
Taking logs on both sides,
xlog8 = log 2
x = log2/log8
x = log2/3log2
x = 1/3

A concentrated cleaning solution must be mixed with water in a container that allows users to spray onto the surfaces they need to clean. Pam’s mom asked her to add 30 ounces of cleaning concentrate into the sprayer and then add water to fill the sprayer. Her father told her that the sprayer must contain 20% cleaning concentrate and 80% water.
a. How many ounces does the sprayer hold?
ounces
b. How much water was added to the sprayer?
ounces
Answer: The sprayer can hold 150 ounces, and Pam needs to add 120 ounces of water.
Step-by-step explanation:
The data that we know is:
We must use 30 oz of cleaning concentrate.
The end product must be 80% water and 20% cleaning concentrate.
This means that:
Mass of water/total mass in the sprayer = 0.8
mass of cleaning concentrate/total mass in the sprayer = 0.2
Then, let's define the variables:
X = ounces that the sprayer can hold.
Y = ounces of water added.
Then we have the equations:
30oz + X = Y.
30oz/Y = 0.20
X/Y = 0.80
From the second equation we can find the value of Y.
30oz = 0.20*Y
30oz/0.20 = Y = 150oz.
Then the sprayer can hold 150 ounces.
Now from the third equation we have:
X/Y = 0.8
We know that Y = 150oz
Then:
X/150oz = 0.8
X = 0.8*150oz = 120 oz.
Then the water that must be added is 120 ounces.

The prime factorization of _________ is 2 (to the fourth power) × 5.
How do you solve with the fourth power thing? I am confused....
Please help as soon as possible :)
Answer:
you times the number by itself the number of times the power is. 10 to the fourth power is 10 times 10 times 10 times 10, etc.
Step-by-step explanation:
For instance 10 to the third power is 1000 because 10 times 10 times 10=1000/
For your example the answer is 2 times 2 times 2 times 2=16. To figure out how much you times it by is if it is to the power of 4, you times it by itself 4 times, power of 5 = times it by itself 5 times, etc. Hope it helps!
