The water depth in a lake decreases at a rate of 2 inches per day because of evaporation. How much does the water depth change in 8 days? In 15 days? In 8 days, the water depth changes by inches. In 15 days, the water depth changes by inches.
Answer: In 8 days it will decrease by 16 inches and in 15 days the water depth changes by 30 inches.
Step-by-step explanation:
The water depth decreases at a rate of 2 inches per day so in this case if were to write it as an expression it will be -2x where x is the number of days.
We will have to set it equal the total amount that it has decreased which will be y.
y= -2x If x represent the number of days we will put in the days and solve for y.
y = -2(8)
y = -16 This means that in 8 days it will decrease by 16 inches.
y = -2(15)
y= -30 This also means that in 15 days the water depth changes by 30 inches.

3n - 5 = -8(6 + 5n)
Answer:
-1
Step-by-step explanation:
Original Equation:
3n - 5 = -8(6 + 5n)
Use distributive property on the parentheses.
-8 ⋅ 6 = -48
-8 ⋅ 5n = -40n
Equation now:
3n - 5 = -48 - 40n
Add 40n to both sides.
43n - 5 = -48
Add 5 to both sides.
43n = -43
Divide both sides by 43
n = -1

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!
How much is it | -7.9|?
Plllzzzzzz help mark you brainliest
Answer:
7.9
Step-by-step explanation:
When a number (or multiple numbers) is placed between two lines like this | |, that is the absolute value grouping symbol. Absolute value is the distance between the grouped number(s) and another defined number. In this case there are no other given numbers so 0 is assumed.
Now, say a friend is driving to your house and you call them to ask how far away they are from arriving (in distance), and they say "Around negative 5 miles away." That doesn't make sense! Distance can never be negative, and because absolute value is the distance between a number and another, a number within that grouping symbol can never be negative if there is a solution. Therefore, |-7.9| would be 7.9, because -7.9 is that exact amount away from 0.

Answer:
11·11^4
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
a = a^1
(a^b)/(a^c) = a^(b-c)
a^0 = 1 . . . . for any 'a' not 0
__
The given expression is ...
(11^8)/(11^3) = 11^(8-3) = 11^5
The offered choices are ...
(11^7)/(11^7) = 11^(7-7) = 11^0 = 1
11·11^4 = (11^1)(11^4) = 11^(1+4) = 11^5 . . . . matches the given expression
(11^0)/(11^5) = 11^(0-5) = 11^-5
11^0 = 1
There are 65 people in a restaurant. The restaurant has a maximum capacity of 84 people. Write an inequality that represents the number x of additional people who can enter the restaurant
Answer:
x+65≤84
Step-by-step explanation:
Inequality that represents the number 'x' of additional people who can enter the restaurant is -
x + 65 ≤ 84
What is inequality?
Inequality refers to a relationship that makes a non-equal comparison between two numbers or other mathematical expressions.
Given is a restaurant which has 65 people in it. The restaurant has a maximum capacity of 84 people.
Assume that 'x' more people can enter inside the restaurant. Then -
the inequality can be written as follows -
x + 65 ≤ 84
65 people were already inside. 'x' more people can enter it such that the total number of people inside is either less or greater than 84.
Therefore, inequality that represents the number 'x' of additional people who can enter the restaurant is -
x + 65 ≤ 84
