Answer:
Sunflower=$900
4WD=$1090
Step-by-step explanation:
Wheareas 2WD costs $29,115 but when converted to 4WD it costs $30,205 then it means the cost of 4WD will be $30205-29115=$1090
The total cost of converting 2WD to 4WD with inclusion of sunroof is $31,105
Therefore, the total cost of 4WD and sunroof will be $31105-$29115=$1990
To get the amount for sunroof, we deduct the total cost that includes 4WD and sunroof from $1090
Cost will be $1990-$1090=$900
A hot air balloon descended 2,250 feet in 15 minutes. Find the change in altitude per minute (show the process).
Answer:
150 ft/min
Step-by-step explanation:
The change in altitude per minute will have the units of ft/min.
We see that we are given the number of feet: 2250 ft, as well as the number of minutes: 15 min.
So, to get ft/min, we can divide 2250 ft (the distance) by 15 min (time) to get the rate: 2250/15 = 150 ft/min
Thus, the change in altitude per minute is 150 ft/min.
Hope this helps!
Answer:
-15 per minute
Step-by-step explanation:
2250/15 = 150
Since it's descending, height is decreasing.
Hence rate of change of height is -15 per minute

Find the equation of the line. Use exact numbers.
y = __x + __
Answer:
y = 3x+3
Step-by-step explanation:
We know the y intercept since it crosses the y axis at (0,3) and we know the x intercept since it crosses the x axis at (-1,0)
We can fidn the slope
m = (y2-y1)/(x2-x1) (0,3) (-1,0)
=(0-3)/(-1-0)
= -3/-1
=3
The equation for the line is in the form
y = mx +b where m is the slope and b is the y intercept
y = 3x+3

What is mean by Rectangle?
A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
The garden is shown in figure.
Width of garden = 1/2x - 7
Length of garden = x
Now,
Since, Width of garden = 1/2x - 7
Length of garden = x
Hence, The perimeter of garden = 2 (Length + Width)
⇒ The perimeter of garden = 2 (x + 1/2x - 7)
⇒ The perimeter of garden = 2 (3/2x - 7)
⇒ The perimeter of garden = 3x - 7/2
Thus, The perimeter of the garden will be;
⇒ 3x - 7/2

Samuel needs 2 boards to make a shelf. One board is 84 centimeters long
and the other is 45 centimeters long.
What is the total length of the shelf?
centimeters
What would your answer be in millimeters?
millimeters
Answer:
The length of the shelf is 129 cm or 1290 mm.
Step-by-step explanation:
Since Samuel will use the two boards to make the shelf, then the total length of the shelf is the sum of the lengths of each board. So in order to solve this problem we must do as shown bellow:
length shelf = length board1 + length board2
length shelf = 84 + 45 = 129 cm
In order to convert this to milimeters we must multiply the answer above by 10. So we have:
length shelf = 129*10 = 1290 mm
The length of the shelf is 129 cm or 1290 mm.
Answer: 129 cm = 1290 mm
Step-by-step explanation:
Hi, to answer this question we simply have to add the length of both boards.
Mathematically speaking:
Total length = 84 cm + 45 cm = 129 centimiters
Since:
1 cm = 10mm
To convert 129 cm to mm we have to multiply it by 10.
129 cm x 10 mm/cm =1290 mm

3% percent of the students at Lincoln High School are in orchestra, 5%
are in band and 1% are in both. If a student is selected at random, what is
the probability that the student is in orchestra OR band?
Answer:
The probability of a student to be in the orchestra or the band is 0.07 or 7%.
Step-by-step explanation:
The probability of a student to be in the orchestra or the band is given by the following formula:
p(orchestra or band) = p(orchestra) + p(band) - p(orchestra and band)
p(orchestra or band) = 0.03 + 0.05 - 0.01
p(orchestra or band) = 0.08 - 0.01
p(orchestra or band) = 0.07
The probability of a student to be in the orchestra or the band is 0.07 or 7%.
Final answer:
The probability that a student is in orchestra or band is 7%.
Explanation:
To calculate the probability that a student at Lincoln High School is in either orchestra or band, we will use the formula for the probability of the union of two events, P(A ∪ B) = P(A) + P(B) - P(A ∩ B), where P(A) is the probability of being in orchestra, P(B) is the probability of being in band, and P(A ∩ B) is the probability of being in both orchestra and band.
In this case, we have been given that 3% of students are in orchestra, 5% are in band, and 1% are in both.
Therefore, we have:
P(orchestra) = 0.03 (3%)P(band) = 0.05 (5%)P(both orchestra and band) = 0.01 (1%)Applying the formula:
P(orchestra OR band) = P(orchestra) + P(band) - P(both orchestra and band) = 0.03 + 0.05 - 0.01 = 0.07
Therefore, the probability that a student is in either the orchestra or the band is 7%.

The center of a circle is (5,-3) and its radius is 4. Which point lies outside of the circle?
Answer:
-1
Step-by-step explanation:
The equation of a circle gives the positions of points inside or on its circumference. A point is outside the circle if the substitution in the equation results in a value greater than the square of the circle's radius.
Explanation:To understand this, we need first to understand the equation of a circle which is defined in the format (x-a)² + (y-b)² = r², where (a,b) is the center of the circle and r is the radius.
In this case, (a,b) = (5,-3) and r = 4. So, the equation of the circle becomes (x-5)² + (y+3)² = 16. Any point (X,Y) that satisfies this equation is inside or at the circumference of the circle. If the computation yields a result greater than 16, the point is outside the circle.
Let's take a point for example: (3,-1). Substituting the values gives (3-5)² + (-1+3)² = 4 + 4 = 8 which is less than 16, hence, lies inside the circle. But for a point like (10,0), it results in (10-5)² + (0+3)² = 25 + 9 = 34 which is greater than 16, so the point (10,0) is outside the circle.

A bookshelf contains 9 mysteries, 7 biographies, and 4 science fiction books. A book is randomly selected, not replaced, then another is selected. Find the probability of selecting a biography then a mystery.
Answer:
63/380
Step-by-step explanation:
Initially,
# of Mysteries, M = 9
# of Biographies, B = 7
# of Sci. Fiction, S = 4
Total number of books = 9 + 7 + 4 = 20 books
P (first book selected is biography) = 7/20
After selecting 1 biography book,
# of Mysteries, M = 9
# of Biographies, B = 7 - 1 = 6
# of Sci. Fiction, S = 4
Total number of books remaining = 9 + 6 + 4 = 19 books
P (second book selected is a mystery) = 9/19
Hence (P first book is biography and 2nd book is mystery)
= (7/20 )(9/19)
= 63/380
The probability of selecting a biography then a mystery is 0.14.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.
Given that, a bookshelf contains 9 mysteries, 7 biographies, and 4 science fiction books.
Total number of outcomes = 9+7+4
= 20
The probability of selecting a biography = 7/20
The probability of selecting a mystery = 9/20
Probability of an event = 7/20 × 9/20
= 56/400
= 0.14
Therefore, the probability of selecting a biography then a mystery is 0.14.

[Find the attachment for the graph]
Final answer:
The equilibrium price for the Seattle Mariners baseball team's seats can be found using economic principles of supply and demand, taking into account factors that influence ticket demand, marginal revenue, and costs.
Explanation:
The question involves determining the equilibrium price for Seattle Mariners baseball team seats. This can be addressed using principles from Economics, specifically the supply and demand model. To determine the equilibrium price, one would need to establish the demand curve, which includes factors such as the population and income of the home city, the team's standing, and the number of superstars on the team. As economists such as Ferguson et al. suggest, the marginal cost for sports teams is often assumed to be zero due to the fixed costs of stadium operations. Therefore, the profit-maximizing quantity of seats sold is where marginal revenue is zero. This can be calculated and visualized with a graph showing both demand and marginal revenue curves. Additionally, adjustments such as the addition of new seats or external fees like licensing can affect the equilibrium dynamics, thus changing the equilibrium price and the total revenue.
