Brett took a test in which 2 points were earned for each correct response and -1/2 point was earned for each incorrect response. He answered 35 questions correctly and 15 questions incorrectly, so his total number of points was 35(2) + [-1/2(15)]. Which is another way to write Brett’s total number of points on the test?
Answer:
35(2) - 1/2(15)
Step-by-step explanation:
35(2) + [-1/2(15)] -----> 35(2) - 1/2(15)
take away the unnecessary extra brackets and replace the plus with a minus sign
hope this helps :)
Another way to write Brett’s total number of points on the test is 35(2) - 1/2(15).
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Brett took a test in which 2 points were earned for each correct response and -1/2 point was earned for each incorrect response.
From the data given in the question:
= 35(2) - 1/2(15)
= 35(2) + [-1/2(15)]
Another way to write Brett’s total number of points on the test:
= 35(2) - 1/2(15)
Thus, another way to write Brett’s total number of points on the test is 35(2) - 1/2(15).

Give two sets of potential sides for a triangle. One set of side lengths should be able to be used for a right triangle and the other set of side lengths should not be able to form a right triangle.
Suppose you’re making a triangle where you know the measures of two angles and the length of the side between those two angles. Write to angle measures and the length of the side between them for your triangle. You can use any measurements you want as long as they could really be used to form a triangle.

What is the equation of the translated function?
A. f(x) = (x – 1)2 – 5
B. f(x) = (x + 1)2 + 5
C. f(x) = (x – 5)2 – 1
D. f(x) = (x + 5)2 + 1
Yes the answer is B
The translated function is f(x) = (x - 1)² + 5.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
The vertex of the original function = (0, 0)
The vertex of the translated function = (-1, 5)
Now,
f(x) → f(x + a) represents a horizontal translation of f(x)
If a > 0 then a shift to the right of a units
If a < 0 then a shift to the left of a units
Vertex = (-1, 5)
This means the translated graph has been shifted to 1 unit left.
So,
f(x) = (x - 1)²
Now,
f(x) → f(x) + c represents a vertical translation of f(x)
If c > 0 then a shift up of c units
If c < 0 then a shift down of c units
Vertex = (-1, 5)
This means,
The translated graph has been shifted 5 units up.
So,
f(x) = (x - 1)² + 5
Thus,
The translated function is
f(x) = (x - 1)² + 5

0 is greater than or equal to 7n
Final answer:
To solve the inequality 0 is greater than or equal to 7n, divide both sides by 7 to get n ≤ 0. This implies n can be any number less than or equal to zero.
Explanation:
The question asks us to solve the inequality 0 is greater than or equal to 7n. This involves understanding inequalities and basic algebraic manipulation. To solve for n, we divide both sides of the inequality by 7, keeping in mind the rules regarding dividing by a positive or negative number. Since 7 is positive, the direction of the inequality remains the same. Thus, we get n ≤ 0.
This means that n can be any number less than or equal to zero for the inequality to be true. It's an important fundamental of algebra that assists in understanding how to work with inequalities and solve them correctly.

Mr. McElroy enjoys listening to his MP3 player, which has 2,000 songs in five different genres of music. He took a sample of the number of each type of song it played on two different one-hour sessions when it was set to play a random mix. The counts are shown in the table below. Which proportion would predict the number of jazz songs he has stored on his MP3 player?
A) 6/20 = x/2000
B) 3/20 = x/2000
C) 2/4 = x/2000
D) 3/40 = x/2000
Answer:
B
Step-by-step explanation:
The required proportion that predicts the number of jazz songs he has stored on his MP3 player is 3/20 = x / 2000.
What is proportionality?proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
From the table number of Jazz songs played = 6
Total song played = 40
Total number of songs in mp3 player = 2000
Number of jazz songs in mp 3 player
6/40 = x /2000
3/20 = x / 2000
Thus, the required proportion that predicts the number of jazz songs he has stored on his MP3 player is 3/20 = x / 2000.

after 1 year on the job, Grady got a raise from $10.50 per hour to $11.34 per hour. what was the percent increase in his hourly wage
Grady's payements or wages for hourly is increased by 8 percent.
What is percent?A Percentage or percent, a relative value indicating hundredth parts of any quantity.
How to caluclate increase in percent?To calcualte the increase in percentage first we subtract the original value from the new value, then divide the result by the original value. Multiply the result by 100.
According to the given question.
The intial payment for one hour was $10.50
And, after one hour the payment is $11.34
⇒ The increment in the payment = $11.34 - $10.50 = $0.84
Therefore,
the percent increase in Grady's hourly wage
[tex]= \frac{increment \ in \ the \ payement}{origibal \ paynent\ } \times 100[/tex]
[tex]= \frac{0.84}{10.50} \times 100[/tex]
[tex]= 0.08 \times 100[/tex]

A Park has a pond shaped like a quadrilateral with all sides 18 feet long and at least one right angle. What geometric shape best describes the shape of the pond?
The pond is best described as a rectangle.
Explanation:The geometric shape that best describes the pond is a rectangle. A rectangle is a quadrilateral with four right angles. Since the pond has all sides of equal length and at least one right angle, it meets the criteria to be a rectangle.

The geometric shape that best describes the shape of the pond is a square or a rectangle.
Given that the pond is shaped like a quadrilateral with all sides 18 feet long, we can immediately rule out shapes that do not have four equal sides, such as parallelograms, trapezoids, and kites. The fact that the pond has at least one right angle further narrows down the possibilities to shapes that have at least one 90-degree angle.
Since all sides are equal in length, and there is at least one right angle, the pond could either be a square (which has four right angles) or a rectangle (which has four right angles but does not necessarily have all sides equal). However, since it is specified that all sides are 18 feet long, the only quadrilateral that fits these criteria is a square.

The Transitive Property of Congruence states that if ∠XYZ ≅ ∠AOB and ∠AOB ≅ ∠WYT, then _____.
a.∠XYZ ≅ ∠ZYX
b.∠XYZ ≅ ∠WYT
c.∠AOB ≅ ∠XYZ
d.∠AOB ≅ ∠AOB
By Transitive property ∠XYZ = ∠WYT.
What is Transitive property?The word "transitive" refers to movement. The transitive property of equality is a property that applies when there are three quantities, a, b, and c, and if a is connected to b and b is related to c by the same rule, then a and c are related to each other by the same rule.
Let's think about the numbers a = b and b = c. Because equality has the symmetric characteristic, writing a = b is equivalent to writing b = a. It follows that b = a and b = c. A must equal c and b since the amount b cannot be equal to two separate quantities.
Given:
∠XYZ ≅ ∠AOB and ∠AOB ≅ ∠WYT
As per the Transitive Property
<X = <Y
and ∠Y = ∠X,
then ∠X = ∠Z.
Similarly,
∠XYZ = ∠AOB
and ∠AOB = ∠WYT,
then ∠XYZ = ∠WYT.
Hence, by Transitive property ∠XYZ = ∠WYT.

The equation V = 5s³ represents the total volume of 5 identical boxes
s represents the each side length
We have to find the total volume
The value of s is given as 1.4
Plug in s value in V formula
V=5(1.4)³
V=5×1.4×1.4×1.4
V=13.72 cubic units
