in order for Brady to earn a b in his biology course, his test scores must average at 80%. ON the first 5 tests, he has an average of 77%. There is one test remaining in the course. What is the minimum score Brady needs to earn on the last test to receive a b in the class?
Answers
(77*5 out of 5*100 points)
So if we want to add a test and have a 80% average this is what we have to do:
(385+x)/6 = 80 (multiply by 6 on both sides)
385 + x = 480 (minus 385 on both sides)
x = 95
Answer:
Brady needs to earn a 95% on the final test
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.
Before we can actually solve this we need to create a formula that calculates the grade of the last test in order to get an average of 80%. Since he got a 77% average for his first 5 tests, we can multiply 0.77 by 5, add the final test and then divide by the total amount of tests taken. Like so,
[tex]0.80 = \frac{(0.77*5)+x}{6}[/tex]
[tex]0.80 = \frac{3.85+x}{6}[/tex] .... multiply both sides by 6
[tex]4.8 = 3.85+x[/tex] ... subtract both sides by 3.85
[tex]0.95 = x[/tex]
Finally, we can see that Brady needs to earn a 95% on the final test in order to increase his overall average to 80%.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

A cell phone plan has a monthly cost that is shown in the table below. What is the correct statement regarding the average rate of change during the 40-minute time of talk? Total minutes of talk time Monthly cost of cell phone 0 $9.95 10 $10.65 20 $11.35 30 $12.05 40 $12.75
Answers
Answer:
The correct statement regarding the average rate of change during the 40-minute time of talk is that the average rate of change of the monthly cost with respect to the talk time is $0.07 per minute.
Explanation:
To find the average rate of change during the 40-minute time of talk, we can calculate the average rate of change of the cost with respect to the number of minutes of talk time.
We can use the formula for average rate of change, which is:
[tex]\[ \text{Average rate of change} = \frac{\text{Change in cost}}{\text{Change in talk time}} \][/tex]
Given the following data:
- At 0 minutes of talk time, the monthly cost is $9.95.
- At 40 minutes of talk time, the monthly cost is $12.75.
Using the formula, we can calculate the average rate of change:
[tex]\[ \text{Change in cost} = 12.75 - 9.95 = 2.80 \][/tex]
[tex]\[ \text{Change in talk time} = 40 - 0 = 40 \][/tex]
[tex]\[ \text{Average rate of change} = \frac{2.80}{40} = 0.07 \][/tex]

Suppose that 5 customers arrive, and each orders a different appetizer to share from a choice of 12 appetizers. In how many ways can this be done?
Answers
The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers is 95,040.
Explanation:The number of ways to choose a different appetizer for each of the 5 customers from a choice of 12 appetizers can be calculated using permutations. In this case, the order in which the appetizers are chosen does matter, and repetition is not allowed since each customer must choose a different appetizer.
To calculate the number of ways, we can use the formula for permutations:
P(n, r) = n! / (n-r)!
Where n is the total number of items and r is the number of items to be chosen.
So, in this case, the number of ways to choose the appetizers is:
P(12, 5) = 12! / (12-5)! = 12! / 7!
Using a calculator simplifies to:
P(12, 5) = 95,040

PLEASE HELP A paperweight in the shape of a rectangular prism is shown: A right rectangular prism is shown with length 10 cm, width 4 cm, and height 4 cm. If a cross section of the paperweight is cut perpendicular to the base, which shape describes the cross section? Parallelogram Triangle Square Hexagon
Answers
Answer: Square
Step-by-step explanation:
Since, the dimension of the given rectangular prism is 10 × 4 × 4
If a cross section of the paperweight is cut perpendicular to the base,
Then the dimension of the resultant quadrilateral is, 4 × 4
That is, the length and breadth is equal,
And the angles are of 90° each,
Which is the condition of a square,
Therefore, the resultant shape will be square.
⇒ Third Option is correct.
The cross section of the paperweight when cut perpendicularly to the base is a square.
Given the following data:
Length of rectangular prism = 10 cm.Width of rectangular prism = 4 cm.Height of rectangular prism = 4 cm.How to determine the resultant shape.We know that the shape of this paperweight is a right rectangular prism. Also, the base area of the paperweight is cut perpendicularly.
This ultimately implies that, the paperweight's length would be removed while its height and width remains, which corresponds to the dimensions (length and width) of a four-shaped object or quadrilateral with an angle of 90 degrees each.
In conclusion, the cross section of the paperweight when cut perpendicularly to the base is a square.

The amount of Sam, Liz, and Ann's candies over three
The algebraic expression for how many candies each girl gets if Sam, Liz, and Ann, who initially had s, l, and a candies respectively, share all their candies evenly is (s + l + a) / 3.
Explanation:This question is referring to a problem in basic algebra. Here we have three individuals: Sam, Liz, and Ann. They each start with a certain number of candies, represented by the variables s, l, and a respectively. The question is asking how many candies each girl has if they all share their candies evenly.
To find this, you would first add up all the candies, which can be represented algebraically as (s + l + a). Since they share equally, you would divide the total number of candies by the number of girls which is three in this scenario. The algebraic expression to represent this would be (s + l + a) / 3. So, each girl gets (s + l + a) / 3 candies.

the exact temperature of a glass of water in degrees Celsius
Answers
To find the exact temperature of a glass of water in degrees Celsius, a thermometer operating on the Celsius scale is used. The Celsius scale marks water's freezing point as 0 °C and it's boiling point as 100 °C with 100 equal intervals in-between these points. Note that the specific heat of water, the amount of heat needed to increase the temperature, is greater than many substances including glass.
Explanation:In order to determine the exact temperature of a glass of water in degrees Celsius, you will use a thermometer that operates on the Celsius scale. The freezing and boiling points of water are key reference points on this scale. When using the Celsius scale, the freezing point of water is defined as 0 °C and the boiling point as 100 °C. The space between these two temperatures is divided into 100 equal intervals, which we define as degrees. Likewise, the Fahrenheit scale has the freezing point of water at 32 °F and the boiling point at 212 °F, a 180-interval scope which is also divided into degrees. Consequently, one degree difference on the Celsius scale is equivalent to 1.8 degrees Fahrenheit difference. Furthermore, the SI unit of temperature is the kelvin (K), but also widely used is the degree Celsius (°C).
The specific heat of a substance, in this case water, also plays a role. The specific heat of water is noticeably higher than that of glass, meaning that more heat is required to raise the temperature of water than glass by an equal number of degrees. Exact values of specific heat for different substances, including water, often have to be looked up in tables because there is no straightforward way to calculate them.
