Angela is playing with red and black marbles. The number of red marbles she has is three
more than twice the number of black marbles she has. She has 42 marbles in all. Which
system of equations can be used to find the number of red marbles, R, and black marbles, B?o
Answer:
We will need two equations, one that adds up to the total number of marbles, and the other which writes one type of marbles in terms of the other.
For the first equation we know that:
[tex]r + b = 42[/tex]
For the second we are told that "The number of red marbles she has is three more than twice the number of black marbles she has."
So we simply translate this into an equation being:
[tex]r = 2b + 3[/tex]
A submarine cruised below the surface of the water. During a training exercise, it made 6 dives, each time descending 35 feet more. Then it rose 122 feet. What is the change in the submarine’s position?
Answer:
68 feet
Step-by-step explanation:
A submarine cruised below the surface of the water
During training exercise, each time descending= 45 feet
Number of dives= 4
Total distance he descended= 45×4 feet
Total distance he descended= 180 feet
Then, it rose by= 112 feet
Now , the distance he is at below the surface if water= 180- 112
The distance he is at below the surface if water= 68 feet
Now, he is at 68 feet below the surface of the Earth
Hence, the correct answer is 68 feet

Rita and Bernie both play the same online game. In today's play, Rita earns 6 points 3 times and loses 4 points twice.
Bernie gets a bonus of 15 points for answering a trivia question correctly and then loses 25 points twice for giving wrong
answers. Choose ALL statements that correctly describe this situation.
Answer:
Rita earns 10 points at the end of the play.
Bernie losses 35 points.
Step-by-step explanation:
Rita earns 6 points 3 time and loses 4 points twice
6 * 3 = 18
4 * 2 = 8

The standard deviation was 7 years. Consider the sampling distribution of sample means based on samples of size 35 drawn from this population.
Required:
What will be the standard deviation of the sampling distribution?
Answer:
The value is [tex]\sigma _x = 1.1832[/tex]
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 25[/tex]
The population standard deviation is [tex]\sigma = 7[/tex]
The sample size is n = 35
Generally the standard deviation of the sampling distribution is mathematically represented as
[tex]\sigma _x = \frac{\sigma}{\sqrt{n} }[/tex]
=> [tex]\sigma _x = \frac{7}{\sqrt{35} }[/tex]
=> [tex]\sigma _x = 1.1832[/tex]

Rosanne makes 1 1/2 liters of strawberry lemonade. She pours 1/4 of a liter of lemonade into a thermos to take to the park. Her brother drinks 2/5 of the remaining lemonade. How much lemonade does rosanne’s brother drink?
Answer:
1/2 liters
Step-by-step explanation:
Rosanne makes 1 1/2 liters of strawberry lemonade
She pours 1/4 of the lemonade into a thermos
The quantity left is
= 1 1/2 - 1/4
= 3/2 - 1/4
= 5/4
Her brother drinks 2/5 of the remaining lemonade
Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows
= 2/5 × 5/4
=1/2
Hence the quantity of lemonade that Rosanne brother drinks is 1/2 liters
Answer:
1/2 liters
Step-by-step explanation: Rosanne makes 1 1/2 liters of strawberry lemonade
She pours 1/4 of the lemonade into a thermos
The quantity left is
= 1 1/2 - 1/4
= 3/2 - 1/4
= 5/4
Her brother drinks 2/5 of the remaining lemonade
Therefore the quantity of lemonade that Rosanne brother drinks can be calculated as follows
= 2/5 × 5/4
=1/2

Answer:
Step-by-step explanation:
What happens to
- the angles on a shape
- the lines on the shape
- the shape itself
when the shape is transformed?
ANSWER:
- When a shape is transformed, the angles on the shape either increase or reduce in size
- When a shape is transformed, the lines on the shape change direction. They could also be shorter, longer, more curved, or more flattened.
- When a shape is transformed, the shape itself becomes another one.
Enter a numerical expression that represents sixty divided by the difference of t cubed and nineteen.
The expression that represents sixty divided by the difference of t cubed and nineteen will be 60 / (t³ - 19).
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The cube of the t is written as t³. Then the difference between the expression t³ and the numerical number 19 will be given as,
⇒ t³ - 19
Then the expression that represents sixty divided by the difference of t cubed and nineteen will be given as,
⇒ 60 / (t³ - 19)
The expression that represents sixty divided by the difference of t cubed and nineteen will be 60 / (t³ - 19).

at its peak in online shopping site was selling about 420 items per second at this rate how many items would it sell in 30 mins( 1800 seconds?)
Answer:.
Step-by-step explanation:
The online shopping site would sell; 756000 items in 30 minutes
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers.
Given that the online site would sell 420 items in a second
To determine the number of items it would sell in 30 minutes first of all convert minutes into seconds.
To convert minutes into seconds, we will just multiply minutes with 60.
WE know that one minute is equal to 60 seconds.
Therefore 30 minutes = 30 x 60 seconds
30 minutes = 1800 seconds
Thus the number of items sold in 30 minutes be x.
now,
420 x 1800 = x
x= 756000
Hence, It is found that the site will sell 756000 items in 30 minutes.
