If a credit card company charges 13.5% yearly interest, which of the following calculations would be used in the process of calculating the monthly interest rate?
Answers
Answer:
(1.135)^[tex]^1/12[/tex]
Step-by-step explanation:
The monthly interest rate is 1.125%
What is rate of change?
The rate of change of a function is the rate at which the output values change over the input value.
The rate of change of a function is one degree less than the actual function.
Here, it is given that :
a credit card company charges 13.5% yearly interest
therefore, to find the rate of interest charged per month divide 13.5% with 12 :
rate of interest charged per month = 13.5%/12
rate of interest charged per month = 1.125%
Therefore, the monthly interest rate is 1.125%

. The area of a rectangle is 2/5 of a inch. If the length is 2/3 of a inch, what is the width
Answers
Answer:
the width of the rectangle is [tex]\frac{3}{5}[/tex] inches
Step-by-step explanation:
The computation of the width is as followS:
As we know that
Area of rectangle = Length × width
Let us assume the width be x
So
[tex]\frac{2}{5} = \frac{2}{3} \times x \\\\\frac{2}{5} = \frac{2x}{3} \\\\10x = 6\\\\x = \frac{6}{10} \\\\= \frac{3}{5}[/tex]
hence, the width of the rectangle is [tex]\frac{3}{5}[/tex] inches

The video rental kiosk rented out 130 videos on Monday, 124 on Tuesday, 80 on Wednesday, and 74 on Thursday. If the kiosk has the same number of rentals over the next four days, how many total videos will have been rented?
Answers
Answer:
816 videos
Step-by-step explanation:
The computation of the total videos rented is as follows:
= Monday + tuesday + wednesday + thursday + friday + saturday + sunday + monday
= 130 + 124 + 80 + 74 + 130 + 124 + 80 + 74
= 816 videos
Here we assume that the question asked for total number of days i.e. 8 days

Matthew has n nickels and d dimes. He has a minimum of $1 worth of coins
altogether. Write this situation as an inequality.
Answers
Answer: [tex]5n + 10d \ge 100[/tex]
===============================================
Explanation:
5n represents the value of all the nickels, where n is the number of nickels. Let's say he had 8 nickels. This would mean 5n = 5*8 = 40 cents is from just the nickels.
The 10d represents the value of all the dimes. For example, if he had d = 2 dimes, then he has 20 cents from those dimes because 10d = 10*2 = 20.
Combining the two expressions leads to 5n+10d as the total value of both types of coins. This total value is in cents. We want this value to be 100 cents or more. This is why we set 5n+10d to be greater than or equal to 100. That's how we arrive to [tex]5n+10d \ge 100[/tex]
Optionally we can divide each term by 5 to get [tex]n + 2d \ge 20[/tex] ,but I'll put the other inequality as the answer because it seems more descriptive in my opinion. Keeping 5n shows each nickel is 5 cents, and 10d shows each dime is 10 cents. Something like n+2d loses a bit of its descriptive nature.
The inequality for the given situation is 5n+10d≥100.
Given that, Matthew has n nickels and d dimes. He has a minimum of $1 worth of coins altogether.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
We know that,
A nickel is worth 5 cents. A dime is worth 10 cents. A dollar is worth 100 cents.
Now, the inequality 5n+10d≥100
Therefore, the inequality for the given situation is 5n+10d≥100.

Sheila can ride her bicycle 6,000 meters in 15 minutes. How far can she ride her bicycle in 3 minutes? please help im retarted
Answers
Answer:
The answer is 1,200 meters
Step-by-step explanation:
So what I did was find the rate so we want to know how much Sheila can do in just 1 minute first so you would have to do 6,000/ 15 which gives you 400 so he does 400 meters in just 1 minute. So then you would have to multiply 400 by 3 which gives you 1,200, making that your answer.
hope that helped!
Answer: 800 meters
Step-by-step explanation:
We first find the speed of Sheila by the speed equation, which is:
v =d/t
d is the total distance traveled
t is the total time taken
And so, we get:
v = 6000m/ 15min
= 400m/min
Now, we find the distance traveled in 2 minutes by solving for distance in the speed equation, which becomes:
d=v⋅t
Inputting our values, we get:
400m/min ⋅ 2min=800

Mina says triangle A with angles
measuring 34° and 57° is similar to
triangle B with angles measuring 57°
and 89º. Is Mina correct?
Answers
Answer:
Yes, Mina is correct
Step-by-step explanation:
Let the triangles be A and B
Given
Triangle A:
[tex]Angles = 34, 57[/tex]
Triangle B:
[tex]Angles = 89, 57[/tex]
Required
Is Mina's claim correct?
First, we calculate the third angle in both triangles.
For A:
[tex]Third\ Angle = 180 - 34 - 57[/tex]
[tex]Third\ Angle = 89[/tex]
For B:
[tex]Third\ Angle = 180- 89 - 57[/tex]
[tex]Third\ Angle = 34[/tex]
For triangle A, the angles are: 34, 57 and 89
For triangle B, the angles are: 34, 57 and 89
Since both triangles have the same angles, then by the postulate of AAA (Angle-Angle-Angle), the triangles are similar.

add 2 to both side 5x-2+2=8x-7+2

2. Almost everyone has played the rock-paper-scissors game at some point. Two players face each
other and, at the count of 3, make a fist (rock), an extended hand, palm side down (paper), or a
"V" with the index finger and middle fingers (scissors). The winner is determined by these rules:
rock smashes scissors, paper covers rock, and scissors cut paper. If both players choose the
same object, then the game is a tie. Suppose that Player 1 and Player 2 are both equally likely to
choose rock, paper, or scissors.
a) Give a probability model for this chance process.
b) Find the probability that Player 1 wins the game on the first throw.
Answers
Answer:
a) Let's suppose that player 1 chooses rock, and the selection of player 2 can be thought as random.
If player 2 randomly selects rock, the result of the game is a draw.
if player 2 randomly selects papers, player 1 loses.
if player 2 randomly selects scissors, player 1 wins.
Then we have 3 options with the same probability, that will be:
1/3
This is, the probability of winning is equal to the quotient between the number of outcomes that make player one win (1, in this case, scissors) and the total number of outcomes (3) = 1/3
the probability of a draw is equal to the quotient between the number of outcomes that make a draw (1, in this case, rock) and the total number of outcomes (3) = 1/3
the probability of losing is equal to the quotient between the number of outcomes that make player one lose (1, in this case, paper) and the total number of outcomes (3) = 1/3
And remember that this will be the same for any selection of the player 1.
b) As we already found, the probability of winning for any selection is 1/3 = 0.333..
