A student’s course grades and their corresponding weights are given in the table.
What is the minimum grade needed on the final exam to earn an overall grade of 85% in the class?
The minimum grade needed to have overall grade of 85% in the class is 90%
What is percentage?A percentage is a number or ratio expressed as a fraction of 100. It is represented by by the symbol %.
Percentage can also be said as per 100
For example if there are total of 100 students in a class and their are 40 girls, the percentage of girls in the class is
40/100 × 100
= 40%
For the student to have a overall grade of 85%, the minimum grade in exam is calculated as
(100+70+80+x)/4 = 85
250+x = 340
x = 340 - 250
x = 90%
Therefore the minimum graded needed is 90%

the area of a trapizoid is 150 square millimeters 7mm 16mm 13mm what is the trapezoids height
The height of the trapezoid is approximately 13.043 mm.
Understanding How to Solve TrapezoidTo find the height of a trapezoid, you can use the formula:
Area = 1/2 * (base1 + base2) * height
Given:
Area = 150 square millimeters
base1 = 7 mm , w
base2 = 16 mm
150 = 1/2 * (7 + 16) * height
150 =1/2 * 23 * height
Make height the subject of the formula
300 = 23 * height
height = 300 / 23
height = 13.043 mm (rounded to three decimal places)
Therefore, the height of the trapezoid is approximately 13.043 mm.

To find the measure of angle AB, we can use the fact that the sum of the angles in a triangle is 180 degrees.
Given:
Angle A = 65 degrees
Angle B = 91 degrees
We can subtract the sum of these two angles from 180 degrees to find angle AB:
Angle AB = 180 - (Angle A + Angle B)
Angle AB = 180 - (65 + 91)
Angle AB = 180 - 156
Angle AB = 24 degrees
Therefore, the measure of angle AB is 24 degrees.
1. ¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
2. [(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
Given statement solution is :- Regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.
Let's analyze the two given statements:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) ∴ ¬(Q ∧ P) ∨ (T ∧ R)
To prove this statement, we can use logical equivalences and deductions:
¬{[Q → (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Given)
¬{[¬Q ∨ (¬S ∧ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{[(¬Q ∨ ¬S) ∧ (¬Q ∨ R)] ∨ ¬P} → (¬P ↔ P) (Implication equivalence)
¬{(¬Q ∨ ¬S ∨ ¬P) ∧ (¬Q ∨ R ∨ ¬P)} → (¬P ↔ P) (De Morgan's Law)
(Q ∧ S ∧ P) ∨ (¬Q ∧ P) → (¬P ↔ P) (De Morgan's Law)
At this point, the formula ¬P ↔ P is a contradiction. The left side (¬P) states that P is false, while the right side (P) states that P is true. Therefore, the whole statement is always true, regardless of the values of Q, S, and P.
Since the statement is always true, we can conclude ¬(Q ∧ P) ∨ (T ∧ R) is true as well, making the second part of the question valid.
[(T ∨ Q) → (T ∨ S)] ∨ [(T ∨ Q) → (T ∨ S)]
In this statement, we have two identical sub-statements connected by a logical OR operator.
If we assume that (T ∨ Q) → (T ∨ S) is true, then the whole statement is true, regardless of the values of T, Q, and S.
If we assume that (T ∨ Q) → (T ∨ S) is false, then we need to check the other part of the statement.
Assuming (T ∨ Q) → (T ∨ S) is false means that (T ∨ Q) is true, but (T ∨ S) is false. In this case, the second part of the statement [(T ∨ Q) → (T ∨ S)] is true.
Therefore, regardless of the values of T, Q, and S, the whole Valid Statements & Implications is always true.

If D = 2w? - w - 7 and C = 3w - 6, find an expression that equals D + 3C in
standard form.
The expression that equals D + 3C in standard form is 2w² + 8w - 25.
To find an expression that equals D + 3C in standard form, we first need to simplify D and C.
Starting with D = 2w² - w - 7, we can rearrange the terms to put it in standard form:
D = 2w² - w - 7
D = 2w² - 2w + w - 7
D = 2w(w - 1) + (w - 7)
Next, simplifying C = 3w - 6:
C = 3w - 6
Now, we can substitute these expressions into D + 3C:
D + 3C = (2w² - w - 7) + 3(3w - 6)
Expanding and simplifying:
D + 3C = 2w² - w - 7 + 9w - 18

What is the volume of a square based pyramid with based side lengths of 6cm, a slant height of 7 cm, and a height of 5cm
Answer:
60 cm^3
Step-by-step explanation:
The formula for volume of a pyramid is
V = 1/3Bh, where B is the area of the base and h is the regular height (aka the altitude that connects the top of the pyramid and the base so we can simply ignore the slant height in the problem)
Step 1: The base of a square pyramid is a square and the formula for area (A) of a square is A = s^2, where s is the side.
Since we're told that the length of the base side length is 6 cm, we can find the area of the base:
A = 6^2 = 36
Step 2: Now, we can plug in 36 for B and 5 for h in the volume formula to find the volume:
V = 1/3(36)(5)

What is the unit rate if you drove a go-kart 9 miles in 36 minutes?
Answer:
Step-by-step explanation:
To find the unit rate, we need to divide the distance traveled by the time taken.
In this case, the distance traveled is 9 miles, and the time taken is 36 minutes.
Unit rate = distance/time
Unit rate = 9 miles / 36 minutes
Simplifying the above expression by dividing both numerator and denominator by 9, we get:
Unit rate = 1 mile / 4 minutes
Therefore, the unit rate at which the go-kart is traveling is 1 mile per 4 minutes.

Line r is steeper than line
Line s
has a negative slope.
Line s has a negative slope.
Line s
is steeper than line r.
Line s is steeper than line
Line r
has a negative slope.
Answer: To determine which statement is true about lines r and s, we need to compare their slopes.
The slope of a line can be calculated using the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
For line r, using the points (-5, 2) and (-3, 8):
slope_r = (8 - 2) / (-3 - (-5))
= 6 / 2
= 3
For line s, using the points (-6, 4) and (2, 12):
slope_s = (12 - 4) / (2 - (-6))
= 8 / 8
= 1
Now, let's analyze the statements:
Line r is steeper than line s. (False)
Since the slope of line r (3) is greater than the slope of line s (1), this statement is true.
Line r is steeper than line (Incomplete statement)
This statement is incomplete.
Line s has a negative slope. (False)
The slope of line s (1) is positive, not negative. So, this statement is false.
Line s is steeper than line r. (False)
Since the slope of line s (1) is less than the slope of line r (3), this statement is false.
Line r has a negative slope. (False)
The slope of line r (3) is positive, not negative. So, this statement is false.
Based on the analysis, the true statement about lines r and s is:
Line r is steeper than line s.

What are the trigonometric ratios?The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:
Sine of angle = length of opposite side to the angle divided by the length of the hypotenuse.Cosine of angle = length of adjacent side to the angle divided by the length of the hypotenuse.Tangent of angle = length of opposite side to the angle divided by the length of the adjacent side to the angle.The altitude of 5375 feet is the opposite angle, hence the position A is obtained as follows:
tan(15º) = 5375/A
A = 5375/tangent of 15 degrees
A = 20060 ft.
The position B is obtained as follows:
B = 5375/tangent of 30 degrees
B = 9310 ft.

Work out the integer values
Please help, I attached a photo.
Step by step explanation if possible :)))
The integers that satisfy the inequality are -1, 0, 1, and 2.
To find the integer values that satisfy the inequality x < 6/(x - 1), we can start by analyzing the domain of the expression.
First, note that the denominator (x - 1) cannot be equal to zero since division by zero is undefined. Therefore, we must exclude x = 1 from the domain.
Next, consider the sign of the expression 6/(x - 1). When the denominator (x - 1) is positive, the expression will be positive. Similarly, when the denominator is negative, the expression will be negative.
Considering the inequality x < 6/(x - 1), we can divide the problem into two cases based on the sign of (x - 1):
Case 1: (x - 1) > 0
In this case, the expression 6/(x - 1) is positive. To satisfy the inequality x < 6/(x - 1), x must be less than the positive value of 6/(x - 1). Since the denominator is positive, we can drop the absolute value sign. Therefore, the inequality becomes:
x < 6/(x - 1)
Case 2: (x - 1) < 0
In this case, the expression 6/(x - 1) is negative. To satisfy the inequality x < 6/(x - 1), x must be greater than the negative value of 6/(x - 1). Since the denominator is negative, we need to flip the inequality sign and change the direction. Therefore, the inequality becomes:
x > 6/(x - 1)
Now, let's solve each case separately:
Case 1: (x - 1) > 0
Since the denominator (x - 1) is positive, we can multiply both sides of the inequality by (x - 1) without changing the direction of the inequality. This gives:
x(x - 1) < 6
Expanding the left side:
x² - x < 6
Rearranging the inequality:
x² - x - 6 < 0
Now we can factorize the quadratic:
(x - 3)(x + 2) < 0
To determine the solution, we need to consider the sign of the expression for different intervals:
When x < -2, both factors are negative, so the expression is positive.
When -2 < x < 3, the first factor (x - 3) is negative, and the second factor (x + 2) is positive, so the expression is negative.
When x > 3, both factors are positive, so the expression is positive.
Therefore, the solution to Case 1 is:
-2 < x < 3
Case 2: (x - 1) < 0
Since the denominator (x - 1) is negative, we need to flip the inequality sign. Multiplying both sides of the inequality by (x - 1) changes the direction of the inequality. This gives:
x(x - 1) > 6
Expanding the left side:
x² - x > 6
Rearranging the inequality:
x² - x - 6 > 0
Factoring the quadratic:
(x - 3)(x + 2) > 0
Considering the sign of the expression for different intervals:
When x < -2, both factors are negative, so the expression is positive.
When -2 < x < 3, the first factor (x - 3) is negative, and the second factor (x + 2) is positive, so the expression is negative.
When x > 3, both factors are positive, so the expression is positive.
Therefore, there are no solutions in Case 2.
Combining the solutions from both cases, we find that the integer values satisfying the inequality x < 6/(x - 1) are:
-2 < x < 3
In other words, the integers that satisfy the inequality are -1, 0, 1, and 2.

area of a rectangular piece of cloth 3 1/4m by 25 cm
Answer:
8125 cm² (or 0.8125 m²)
Step-by-step explanation:
area of a rectangular piece of cloth 3 1/4m by 25 cm
the area of the rectangle is found by making the base by the height, we convert the meters into centimeters
3 1/4 m = 3.25m = 325 cm
we find the area
325 × 25 = 8125 cm² (or 0.8125 m²)
