What are the steps of adding and subtracting fractions?The steps for adding and subtracting fractions are as follows:
Step 1: Match the denominators.
Step 2: Add and subtract the numerators.
Step 3: Make the fraction simpler.
Fractions with different denominators can be added or subtracted by using Least Common Multiple(LCM) to convert them to like fractions.
a) 4/5 - 1/5
The denominators of the fractions are the same so we have to just subtract the numerators.
= (4 - 1)/5
= 3/5
b) 9/11 + 5/11
Similarly, the denominators of these fractions are also equal so we have to just add the numerators.
= (9 + 5)/11
= 14/11
c) 3/4 + 1/8
First, we find the Least Common Multiple (LCM) of the denominators to convert them into like denominators and then add the respective numerators.

Joshua and Amahle are selling boxes of fruit for a Habitat for Humanity fundraiser. Customers can buy small
boxes of fruit and large boxes of fruit. Joshua sold 15 small boxes of fruit and 15 large boxes of fruit for a
total of $390.00. Amahle sold 20 small boxes of fruit and 25 large boxes of fruit for a total of $592.50. Find the cost of one small box of fruit and the cost of one large box of fruit.
Cost of small box: $
Cost of large box: $
Answers
The cost of one small box of fruit and the cost of one large box of fruit is $11.5 and $14.5 respectively.
What is the cost of small and large box?Let
cost of one small box of fruit = x
cost of one large box of fruit = y
15x + 15y = 390
20x + 25y = 592.50
From (1)
x + y = 26
x = 26 - y
Substitute x = 26 - y into (2)
20x + 25y = 592.50
20(26 - y) + 25y = 592.50
520 - 20y + 25y = 592.50
- 20y + 25y = 592.50 - 520
5y = 72.50
divide both sides by 5
y = 72.50/5
y = 14.5
Substitute y = 14.5 into
15x + 15y = 390
15x + 15(14.5) = 390
15x + 217.5 = 390
15x = 390 - 217.5
15x = 172.5
divide both sides by 15
x = 172.5/15
x = 11.5
Therefore, small box cost $11.5 and large box cost $14.5

Describe Vertical Angles?Vertical angles are a pair of angles that are formed by the intersection of two straight lines. They are opposite angles, meaning they are located across from each other and have the same measure. Vertical angles are congruent, which means they have the same angle measure.
For example, if two lines intersect at a point, they form four angles, with two pairs of vertical angles. If one of the angles has a measure of 30 degrees, then the opposite angle (the vertical angle) will also have a measure of 30 degrees.
Since vertical angles are congruent, we have:

The point slope equation and slope of some lines are given below
1) For y - 6 = 3(x - 5), slope = 3
2) For y - 4 = -9(x + 8), slope = -9
3) y - 2 = 5x, slope = 5
4) Point slope equation of line whose slope = -10 and passing through (1, 4)
y - 4 = -10(x - 1)
5) Point slope equation of line whose slope = 2 and passing through (5, -3)

6) Point slope equation of line whose slope = \(\frac{1}{2}\) and passing through (-7, -7)
\(y +7 = \frac{1}{2}(x +7)\\\)
What is equation of line in point slope form?
The most general form of equation of line in point slope form is given by \(y - y_1 = m(x - x_1)\) , \((x_1, y_1)\) is a point on the line
Where m is the slope of the line
Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.
If \(\theta\) is the angle that the line makes with the positive direction of x axis, then slope (m) is given by
m = \(tan\theta\)
1) y - 6 = 3(x - 5)
y - 6 = 3x - 15
y = 3x - 15 + 6
y = 3x - 9
Slope = 3
If x = 0,
\(y = 3 \times 0 -9\\y = -9\)
(0, -9) is a point on the line
2) y - 4 = -9(x + 8)
y - 4 = -9x - 72
y = -9x - 72 + 4
y = -9x - 68
Slope = -9
If x = 0
\(y = -9 \times 0 -68\\y = -68\)
(0, -68) is a point on the line
3) y - 2 = 5x
y = 5x + 2
Slope = 5
Putting x = 0
\(y = 5 \times 0 + 2\\y = 2\)
(0, 2) is a point on the line
4) Slope = - 10
The line passes through (1, 4)
Point slope equation
y - 4 = -10(x - 1)
5) Slope = 2
The line passes through (5, -3)
Point slope equation
y - (-3) = 2(x - 5)
y + 3 = 2(x - 5)
6) Slope = \(\frac{1}{2}\)
The line passes through (5, -3)

At an amusement park, guests have to take either a train or a boat 22 miles from the parking lot to the front entrance and then back when they leave the park. The train goes 10 mph faster than the boat . Abdul takes the train into the park and the boat on his way back. The boat goes an average speed of 20 mph. How long did the round trip take?
Answers
Answer:
1 hour 50 minutes
Step-by-step explanation:
Total distance from parking lot to entrance = 22 miles
We will assume that the total distance from entrance to lot is also 22 miles
The average speed of the boat = 20mph
The average speed of the train is 10 mph faster = 20 + 10 = 30 mph
Time taken for travel from parking lot to park by train = 22/30 hours
22/30 hours = 22/30 x 60 minutes = 44 minutes
On the way back, the boat was taken
Distance = 22 miles, speed = 20 mph
Time taken = distance/speed = 22/20 hours
22/20 hours = 22/20 x 60 minutes = 66 minutes
Total round trip time taken = 44 + 66 = 110 minutes
110 minutes = 110/60 hours
= 1 50/60 = 1 hour 50 minutes
3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answers
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

OC. Yes, they are independent, because P(girl) ≈ 0.46 and P(girl | plays

Answers
The answer is D. No, they are not independent, because P(girl) = 0.46 and P(girl | plays a sport) = 0.54.
What is independent event ?
In probability theory, two events A and B are said to be independent if the occurrence of one event does not affect the probability of the occurrence of the other event. That is, the probability of A occurring does not change based on whether B occurs or not, and vice versa.
Mathematically, two events A and B are independent if and only if the probability of their joint occurrence is the product of their individual probabilities:
P(A and B) = P(A) x P(B)
If this equation holds true, then we can say that A and B are independent events. Otherwise, they are dependent events.
According to the question:
The answer is D. No, they are not independent, because P(girl) = 0.46 and P(girl | plays a sport) = 0.54.
Two events A and B are independent if the occurrence of one event does not affect the probability of the occurrence of the other event. In this case, we want to know if being a girl and playing a sport are independent events.
We are given that P(girl) = 0.46, which means that 46% of the students surveyed are girls. We are also given that P(girl | plays a sport) = 0.54, which means that 54% of the students who play a sport are girls.
If being a girl and playing a sport were independent events, then we would expect P(girl | plays a sport) to be equal to P(girl). However, we see that P(girl | plays a sport) = 0.54, which is different from P(girl) = 0.46.
This means that the probability of a student playing a sport is dependent on their gender. Therefore, being a girl and playing a sport are not independent events.

A lamppost casts a shadow of 18 ft when the angle of elevation of the Sun is 33.7 degrees. How high is the lamppost? Round to the nearest foot
Answers
Answer:
12 feet or 12 ft
Step-by-step explanation:
We solve for this question using Trigonometric function of Tangent
tan θ = Opposite/ Adjacent
θ = Angle of elevation = 33.7°
Opposite side = Height of the lamp = ??
Adjacent side = Shadow of the lamp = 18 feet
Hence,
tan 33.7° = Opposite/ 18
tan 33.7° × 18 = Opposite
Opposite = 12.004507735 feet
Approximately to the nearest foot = 12.0feet
The height of the lamppost with a shadow of 18 ft. is 12 feet.
Trigonometric ratio
Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.
Let h represent the height of the lamppost, hence:
tan(33.7) = h/18
h = 12 feet

The point P=(1/2,y)lies on the unit circle shown below. What is the value of y in simplest form?
Answers
The value of y in simplest form for the point P = (1/2, y) lying on the unit circle is y = ± √(3)/2.
To find the value of y in simplest form for the point P = (1/2, y) lying on the unit circle, we can use the equation of the unit circle, which states that for any point (x, y) on the unit circle, the following equation holds: x^2 + y^2 = 1.
Plugging in the coordinates of the point P = (1/2, y), we get:
(1/2)^2 + y^2 = 1
1/4 + y^2 = 1
y^2 = 1 - 1/4
y^2 = 3/4.
To simplify y^2 = 3/4, we take the square root of both sides:y = ± √(3/4).
Now, we need to simplify √(3/4). Since 3 and 4 share a common factor of 1, we can simplify further: y = ± √(3/4) = ± √(3)/√(4) = ± √(3)/2.

Roselyn is driving to visit her family, who live 150 kilometers away. Her average speed is 60 kilometers per hour. The car's tank has 20 liters of fuel at the beginning of the drive, and its fuel efficiency is 6 kilometers per liter. Fuel costs 0.60 dollars per liter. How long can Roselyn drive before she runs out of fuel?
Answers
Roselyn can drive a distance until she runs out of fuel for a time of 2.5 hours or until she spends all the fuel, whichever comes first.Roselyn can travel 120 km before running out
Distance travelled with 20 l of petrol in solution and final answer.
Roselyn's average speed is 60 kilometers per hour, and she needs to travel 150 kilometers to reach her family's place. Therefore, she will require a total of 150/60 = 2.5 hours to complete the journey.
The car's fuel efficiency is 6 kilometers per liter, meaning it consumes 1/6 liters of fuel per kilometer. To determine the total fuel required, we multiply the fuel consumption rate by the total distance: 150 * (1/6) = 25 liters of fuel.
Since the car's tank has 20 liters of fuel at the beginning of the drive, Roselyn will need an additional 25 - 20 = 5 liters of fuel to complete the journey.
As fuel costs 0.60 dollars per liter, Roselyn will need to spend a total of 5 * 0.60 = 3 dollars to purchase the necessary fuel.
Therefore, Roselyn can drive until she runs out of fuel for a time of 2.5 hours or until she spends all the fuel, whichever comes first.

Answer:
see attached for a sketch
area = 5 1/3 square units
Step-by-step explanation:
You want the area under the square root curve, above y=0, from x=0 to x=4.
AreaThe area is found by integrating a differential of area over appropriate limits. A vertical slice will have hight √x and width dx, so we have ...
dA = (√x)dx
A = ∫(√x)dx
The power rule can be used for the integration:
\(\displaystyle A=\int_0^4{x^{\frac{1}{2}}}\,dx=\left[\dfrac{x^{\frac{3}{2}}}{\frac{3}{2}}\right]^4_0=\dfrac{2}{3}(4^\frac{3}{2})=\dfrac{16}{3}=\boxed{5\dfrac{1}{3}}\)
The area of the region is 5 1/3 square units.

Additional comment
You will notice that the area is bounded by a rectangle 4 units wide and 2 units high, for an area of 4·2 = 8. The area under the parabolic curve is 2/3 of that: 2/3·8 = 16/3 = 5 1/3 square units.
This fraction will be true for any area bounded by a parabola where the vertex is one of the corners of the rectangle.
