The second equation, representing the total cost of both apples as 0.75d + 1.25g = 21.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that Mary used Delicious (d) and Golden Delicious (g) apples to make homemade applesauce. Delicious apples are $0.75 each and Golden Delicious apples are $1.25 each. Mary spent $21.00 on 22 apples.
Assume that the number of Delicious apples are (d) and Golden Delicious are (g) apples.
We can write the second equation as -
0.75d + 1.25g = 21
and the first equation as -
d + g = 22
Therefore, the second equation, representing the total cost of both apples as 0.75d + 1.25g = 21.

If you work 52 weeks/year and 40 hours/week, how many hours would you work in one year? quizlrt
Final answer:
To find the total hours worked in a year, multiply the number of hours worked per week by the number of weeks in a year.
Explanation:
To calculate the total hours worked in a year:
Hours worked per week = 40 hours
Weeks worked per year = 52 weeks
Total hours worked in a year = 40 hours/week x 52 weeks = 2080 hours
A boat is 122 meters from the base of a lighthouse that is 34 meters above sea level. What is the angle of elevation from the boat to the top of the lighthouse? Round to the nearest degree. °
Answer: 16
Step-by-step explanation:
A pilot flies 720 miles from dallas, texas, to his first destination. after dropping off his cargo, he flies southeast 290 miles to his second destination. if the angle formed by his trip is 125°, what is the distance he will fly from the second destination back to dallas? 490 miles 918 miles 1,010 miles 842,026 miles
Answer:
B) 918 miles
Step-by-step explanation:
Here with I have attached the figure of the story.
Here we need to find side c, which represents distance from the second destination back to Dallas.
We have to use the cosine formula to find the missing side.
If we are given two sides and one included angle, we can use the cosine formula and find the missing side.
a = 720, b = 290 and ∠C =125°
[tex]c^2 = a^2 + b^2 - 2ab cos C[/tex]
Now plug in the given values and simplify.
[tex]c^2 = {720}^2 + 290^2 - 2*720*290 cos 125[/tex]
[tex]c^2 = 518400 + 84100 - 417600 cos125[/tex]
[tex]c^2 = 602500 - (-239,525.5)\\c^2 = 602500 + 239,525.5\\c^2 = 842025.5[/tex]
Taking the square root on both sides, we get
c = 917.6
Which is equivalent to 918 miles (rounded off to the nearest whole number)

Segment AB has endpoints A(–4, 6) and B(1, 4). After a dilation, centered at the origin, the image of A is (–6, 9). Without measuring the distance, explain how you could find the image of B
The image of point B is B'(1.5,6).and this can be determined by finding the dilation factor and then multiplying point B by the dilation factor.
Given :
Segment AB has endpoints A(–4, 6) and B(1, 4).After a dilation, centered at the origin, the image of A is (–6, 9).In order to determine the image of point B, first, determine the dilation factor. let 'x' be the dilation factor, then:

What is the value of x in the figure?
Enter your answer in the box.
x =
Answer:
The value of x in the given figure is, [tex]34^{\circ}[/tex]
Step-by-step explanation:
Complementary angle states that the two angles sum up to 90 degree.
From the given figure
[tex]x^{\circ}[/tex] and [tex]56^{\circ}[/tex] are complementary angles.
by definition of complementary angles;
[tex]x^{\circ} +56^{\circ} = 90^{\circ}[/tex]
Subtract [tex]56^{\circ}[/tex] from both sides we get;
[tex]x^{\circ} = 90^{\circ} -56^{\circ}[/tex]
Simplify:
[tex]x = 34^{\circ}[/tex]
therefore, the value of x in the given figure is, [tex]34^{\circ}[/tex]
Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1000 was collected and 150 tickets sold. How many of each kind of ticket were sold? Write a system of equations and use substitution to solve.
To solve this problem, set up a system of equations representing the number of student and adult tickets sold. Solve the system using substitution to find the numbers of each type of ticket sold.
Explanation:To solve this problem, we can set up a system of equations to represent the number of student tickets and adult tickets sold.
Let x be the number of student tickets sold and y be the number of adult tickets sold.
We know that the total number of tickets sold is 150, so we have the equation:
x + y = 150
We also know that the total amount collected is $1000, so we have the equation:
3x + 8y = 1000
We can solve this system of equations using substitution.
From the first equation, we can solve for x in terms of y as:
x = 150 - y
Substituting this into the second equation, we have:
3(150 - y) + 8y = 1000
Simplifying, we get:
450 - 3y + 8y = 1000
Combining like terms, we get:
5y = 550
Dividing both sides by 5, we get:
y = 110
Substituting this value back into the first equation, we have:
x + 110 = 150
Simplifying, we get:
x = 40
Therefore, 40 student tickets and 110 adult tickets were sold.

A florist sold 15 arrangements in its first month of business. The number of arrangements sold doubled each month.
What was the total number of arrangements the florist sold during the first 9 months?
Answer:
total number of arrangements the florist sold during the first 9 months = 7665 arragements
Explanation:
Florist start a business.
In his 1st month Florist sold 15 arrangement.
He grow his business, he sold twice arrangements as compare to the previous month.
First month = 15
Second month = 2*15 = 30
Third month = 2*30 = 60
15, 30, 60 .....
we need to find the total number of arrangements in first nine months
This sequence is geometric series.
A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term, i.e.,
r = [tex] \frac{30}{15} = \frac{60}{30} = 2 [/tex]
Sum of Terms in a Geometric Progression ([tex] S_{n} [/tex])= [tex] \frac{a_{1} (r^{n} -1)}{r-1} [/tex]
where [tex] a_{1} [/tex] is first term = 15
n is the number of terms = 9
r is common ratio = 2
[tex] S_{9} =\frac{15(2^{9}-1)}{2-1} [/tex]
[tex] S_{9} =\frac{15*(512-1)}{1} [/tex]
[tex] S_{9} = 7665 [/tex]
total number of arrangements the florist sold during the first 9 months = 7665.

A.
0.013
B.
0.032
C.
0.215
D.
0.785
Answer: C. 0.215
Step-by-step explanation:
Given: A circle with a diameter of 124 m is inscribed in a square .
Thus side of square =124 m
Now, area of square=[tex](side)^2=(124)^2=15,376\ m^2[/tex]
Radius of circle=[tex]\frac{d}{2}=\frac{124}{2}=62\ m[/tex]
Area of circle=[tex]\pi\ r^2=3.14\times(62)^2=3.14\times3.14=12,070.16\ m^2[/tex]
Now, Area of shaded region= Area of square-Area of circle
Area of shaded region=[tex]15,376-12,070.16=3,305.84\ m^2[/tex]
Probability that a point picked at random in the square is in the shaded region
[tex]=\frac{\text{area of shaded region}}{\text{area of square}}=\frac{3305.84}{15376}=0.215[/tex]

The roof of a factory rises vertically 7 ft through a horizontal run of 42 ft. What is the pitch of the roof?
Final answer:
The pitch of the roof, which rises vertically 7 ft through a horizontal run of 42 ft, is 2. This means the roof rises 2 inches for every 12 inches of horizontal run.
Explanation:
The question asks about calculating the pitch of a roof with a vertical rise of 7 ft and a horizontal run of 42 ft. The pitch of a roof is generally expressed as the amount of vertical rise per 12 inches of horizontal run. To find the pitch, we first need to calculate the rise per 12 inches of horizontal run.
Given:
Rise = 7 ft
Run = 42 ft
To find how much the roof rises for every 12 inches of run, we use the formula:
Pitch = (Rise / Run) × 12
Plugging in the given values:
Pitch = (7 / 42) × 12 = 2
Thus, the pitch of the roof is 2, meaning the roof rises 2 inches for every foot (12 inches) of horizontal run.
