Answer:
$13.50
Step-by-step explanation:
Hardcover Books = $18.25 each
Softcover Books = $5 each
She bought 2 hardcover and 2 softcover.
Hardcover: $18.25 + $18.25 = $36.50
We already know what 2 softcover books cost ($10)
No add those both together.
$36.50 + $10.00 = $46.50
She gives the clerk $60
$20 + $20 = 40
$20 + $20 = 40
$20 - $6.50 = $13.50

For 15 points.Explain, in your own words, the steps necessary to solve a system of equations
using the substitution method.
Answers
First, what is an equation?
➳ A mathematical statement which shows that two algebraic expressions are equal is called and equation.
Or, LHS = RHS
Example:- 3x - 5 = x + 8
An equation is said to be a linear equation if it contains only one variable (literal) with highest power 1.
_______________________
Solving an equation:-
To solve the equation x + 5 = 7 means to find the value of an unknown algebraic quantity used in the equation.
Example:-
To solve the equation x + 5 = 7 means to find the value of x.To solve the equation 3y + 2 = 9 means to find the value of y.To solve the equation [tex]\sf \dfrac{2a}{3} + 4 = 10[/tex] means to find the value of a ⠀⠀⠀⠀⠀⠀and so on!⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
★ Rules for solving an equation by the substitution method:-
Rule ❶
If x = 2, the value of the expression 3x + 2 = 3 × 2 + 2 = 6 + 2 = 8
Rule ❷
If x = 0, the value of the expression 3x + 2 = 3 × 0 + 2 = 0 + 2 = 2
Rule ❸
If x = -2, the value of the expression 3x + 2 = 3 × -2 + 2 = -6 + 2 = -4
Now consider the algebraic expression 5x - 2y
This expression consists of variables x and y.
Now if :-
x = 3 and y = 2, 5x - 2y = 5 × 3 2 × 2 = 15 - 4 = 11x = 8 and y = 5, 5x - 2y = 5 × 8 - 2 × 5 = 40 - 10 = 30⠀⠀⠀⠀⠀⠀⠀⠀
The process of finding the value of an algebraic expression by substituting the given value of its variable is called substitution.⠀⠀

Answers

Answer:
$2000
Step-by-step explanation:
The amount of interest is given by the formula ...
I = Prt
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we want to find P when I = 50, r = 0.05, and t = 1/2.
50 = P(0.05)(1/2)
P = 50/(0.05·1/2) = 2000

A. How many views would you expect the video to have after 5 days? Explain how you found your answer.
B. Which type of reasoning did you use to solve this problem, deductive or inductive? (2 points)
Answers
Answer:
(A) 5th day: 405 views
(B) inductive
Step-by-step explanation:
Each day the views get multiplied by 3.
Answer:
A. I would expect the video to have 405 views after day 5. There is a pattern of the number being multiplied by 3.
B. Deductive reasoning
Step-by-step explanation:
(This is really going to explain BOTH questions at the same time)
Looking that the problem, the number of views keep going up. There is a multiplier behind this, we just don't know WHAT multiplier it would be. To find that out, divide 1 value by the one before it. I'll do 135 divided by 45 as an example. That would equal three. Now we know the multiplier is 3. So, now we need to multiply 135 by 3 to get 405 views after five days.

The formula for circumference is: [tex]2\pi r[/tex]. In this case, the r (radius) is 2.3. Multiply it by 2 to get the diameter or 4.6. Then multiply 4.6 x [tex]\pi[/tex] (pi) to get 14.444. This rounded to the nearest tenth of a centimeter is 14.4.

20 meters
25 meters
50 meters
250 meters
Answers
Answer: 20 meters
Step-by-step explanation:
We are told that an oblique cylinder has a radius of 16 meters and a volume of 5,120 pi cubic meters. We will use volume of oblique cylinder to find the height of our given cylinder. volume of a oblique cylinder= πr²hUpon substituting our given values in above formula we will get,5,120π m³ = π ( 16 m² × h )
5,120π m³ = π × 256 m² × h
Let us divide both sides of our equation by 100 pi.Therefore, height of our given oblique cylinder is 20 meters.

If you randomly select a card from a well-shuffled standard deck of 52 cards, determine the probability that the card you
select is a 6.
a) Write your answer as a reduced fraction.
b) Write your answer as a decimal, rounded to the nearest thousandth.
c) Write your answer as a percent. Round to the nearest tenth of a percent as needed.
Answers
Answer:
a. 1/13
b. 0.077
c. 7.7
Step-by-step explanation:
a. there are 4 of the 6 in a deck of cards so the probability of taking this cards from the deck of 52 cards is 4/52. Given you 1/13.
Probability is the chance of an event to occur from a total number of outcomes.
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of cards = 52
The number of cards randomly selected = 1
The number of cards that is 6 in a deck of 52 cards:
= 4
i.e
6 of spade
6 of diamond
6 of hearts
6 of club
Now,
The probability that a randomly selected card from a deck of
52 cards is 6:
= Number of cards that is 6 / Total number of cards
= 4 /52
The answer in the reduced fraction of 4/52 is 1/13
The answer in decimal:
= 4/52
= 0.0769
Rounding to its nearest thousandth.
= 0.077
The answer as a percent:
= 4/52 x 100
= 0.0769 x 100
= 7.69 %
Rounding to the nearest tenth.
= 7.7 %
Thus,
The answer in the reduced fraction is 1/13
The answer in decimal is 0.077
The answer as a percentage is 7.7 %
