Answer:a
Step-by-step explanation:
problem solving you go on a hayride to take photographs of landmarks. the map shows your path and two landmarks. each unit in the coordinate plane corresponds to 10 yards. approximate your minimum distance from the giant pumpkin. if necessary, round your answer to the nearest tenth.
The minimum distance from the giant pumpkin is 8.9 yards.
We will use the minimum distance formula between a line and a point to obtain the distance in this case.
A linear function is given according to the standard notation by:
Ax+By+C=0
A point with 'x' and 'y' coordinates are given by:
P(x*,y*)
The formula to find the shortest distance between a point and a line is denoted by the formula:
d=|Ax*+By*+C|/√(A²+B²)
In this issue, the path's line includes:
When x = 0, and y = 0, the intercept is 0.
0.5 slope means that when x rises by 4, y rises by 2.
Thus, y=1/2x
-1/2x+y=0
or, -x+2y=0
The coefficients of the line are:
A=-1 and B=2
Coordinates of the giant pumpkin is (x*,y*)=(-4,-3)
Therefore, the minimum distance is:
d=|(-1)(-4)+2(-3)|/√5
or,d=2/√5
or, d=0.89 units
We know, 1 unit=10 yards
or, 0.89 units=8.9 yards
Thus, the minimum distance between a point and a line is 8.9 yards.

specify the number of significant figures in each of the following numbers and determine the result of the following calculation to the correct number of significant figures. 3.115 0.2281 712.5 45
The result of the calculation is 680.
The number 3.115 has four significant figures, the number 0.2281 has four significant figures, the number 712.5 has three significant figures and the number 45 has two significant figures. This means that when performing calculations with these numbers, the answer must be rounded to the least number of significant figures, which is two.
The calculation is 3.115 + 0.2281 + 712.5 - 45. Using the rules of significant figures, we can calculate this as 3.1 + 0.2 + 713 - 45.

Given right triangle ABC, where side "c" is the hypotenuse, angle A measures 50 degrees, and side b measures 13 m, find the length of side c.
Answer:
In a right triangle, the angle opposite the hypotenuse (side c) is always 90 degrees, so we can use the trigonometric function sine to find the length of side c.
sin(A) = opposite / hypotenuse
sin(50) = b / c
so c = b / sin(50)
c = 13 m / sin(50)
c ≈ 22.361 m
So the length of side c is approximately 22.361 meters
What is angle q in the triangle that is shown below? Side x =
66.1 cm, side y = 22.8 cm, and angle f = 23.3º.
Please round your answer to one decimal place.
In the triangle, we will use the Law of Cosines to find the value of angle q. angle q in the triangle is approximately 61.2° (rounded to one decimal place).
What is Law of Cosines?The Law of Cosines is a mathematical formula used in trigonometry to find the length of a side or an angle in a triangle.
The formula can be used to find the length of a side or an angle in a triangle, given the length of the other sides and angles.
The Law of Cosines is particularly useful when only two sides and the angle between them are known, or when only two angles and the side between them are known.
To use the Law of Cosines, you need to identify the sides and angles that you know and plug them into the formula. Then, you can use algebra to solve for the unknown side or angle.
The Law of Cosines is related to the Pythagorean Theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
The Law of Cosines can also be used in three-dimensional geometry to find the distance between two points in space.
The Law of Cosines is a useful tool in many fields, including engineering, physics, and computer graphics, and is widely used in solving geometric problems.
In this triangle, we have x = 66.1 cm, y = 22.8 cm, and angle f = 23.3º. We want to find angle q, which is opposite side x.
We can use the Law of Cosines to find the value of cos(q), and then use the inverse cosine function to find the value of q in degrees.
cos(q) = (x² + y² - x²)/(2xy)
cos(q) = (66.1² + 22.8² - 22.8²)/(2 * 66.1 * 22.8)
cos(q) = 67.8664/150.6448
cos(q) = 0.449
q = cos⁻¹(0.449)
q = 61.2°
Therefore, angle q in the triangle is approximately 61.2° (rounded to one decimal place).

The graphs of two equations in a linear system have the same x-intercept. One equation in the system is 1/5x + 4y = a . What is the solution of the system?
This means x = 5a pairs up with y = 0.
=========================================================
Explanation:
The two lines have the same x-intercept, which means they cross the x axis at the same location. This is the solution to the system since this point is on both lines simultaneously.
To find the x-intercept, plug in y = 0 and solve for x.
(1/5)x+4y = a
(1/5)x+4*0 = a
(1/5)x = a
x = 5a
We don't know the value of 'a', so we cannot determine the numeric value of x.
The x-intercept is located at (x,y) = (5a,0) and this is the solution to the system.

A jar contains nickels, dimes and quarters in a ratio of 2:3:5 respectively. If there are 85 quarters, how many more dimes and there in a jar than nickels?
The number of dimes more than nickels in the jar is 17.
How many more dimes are there ?The first step is to determine the total number of coins in the jar.
Total number of coins in the jar = (sum of ratios x number of quarters) / ratio that represents the number of quarters
Sum of ratios = 2 + 3 + 5 = 10
Total number of coins in the jar = (10 x 85) / 5 = 170
Number of dimes in excess of nickels = [(ratio representing dimes - ratio representing quarters) / sum of ratios) x total number coins
[(3 - 2) / 10] x 170
(1/10) x 170 = 17

The value of x is -20 and can be calculated using basic proportionality theorem.
What is Basic Proportionality Theorem?The Basic Proportionality Theorem, often known as the Thales Theorem, was developed by the well-known Greek mathematician Thales.
Basic Proportionality Theorem asserted that the ratio of any two related sides is always the same for any two equiangular triangles.
Thales provided the basic proportionality theorem based on this idea (BPT). Similar triangles have introduced this idea before. If two triangles resemble one another, then
The corresponding angles of both triangles are equal.
The corresponding sides of both triangles are proportional to one another.
Since the ratio of other side pair is 1:1, similarly 4x+20 = 3x
20 = 3x-4x
20 = -x
x = -20

Find the lateral surface area of the solid above.
Answer here
The answer for lateral surface area of the Triangular prism is 180 cm²
What is Lateral Surface Area?Any solid object's lateral area can be calculated using the lateral area formula. Any figure's lateral area only includes the non-base faces. Calculating the lateral surface area of various forms, such as the cuboid, cube, cylinder, cone, and sphere, is made easier using lateral area formulas.
The lateral area for a triangular prism
A triangular prism's lateral area is equal to the sum of its side faces' areas (which are 3 rectangles). Specifically, it is the total surface area less the surface areas of the two bases. Additionally called the lateral surface area (LSA). Due to the two dimensions involved in its calculation, we measure it in square units.
The total of the three regions is the triangular prism's lateral area. Consequently, the triangular prism's lateral area formula is
Triangular prism lateral surface area (LSA) = ah + bh + ch (or) (a + b + c) h.
We are aware that the perimeter of the base is (a + b + c) (triangle). Hence,
Triangular prism's lateral surface area (LSA) is equal to the product of the base's perimeter and the prism's height.
base perimeter × height
Explanation
The Given Image of the solid is Matching to a prism.so we are calculating the lateral surface area of the prism
The dimensions of each base are:
a = 5cm
b = 4 cm
c = 3 cm
The height of the triangular prism = 15cm.
Thus, the lateral area of triangular prism = (a + b + c ) h
= (5 + 4 + 3) 15
= (12) 15
= 180 cm²
Answer: The lateral area of the given triangular prism = 180 cm²

Four friends shared the cost of a pizza dinner. They ordered 1 large pizza for $17.50, 4 sodas for $1.25 each, and 4 salads. Salads normally cost $1.75 but were on sale: "Buy one, get one free." If the friends split the total cost of dinner equally, what was each person's share?
Answer:
$6.50
Step-by-step explanation:
So writing out everything
1 Pizza = $17.50
1 soda = $1.25
1 salad = $1.75
Exception; Salad is buy 1 get 1 free, so only 2 salads were paid for
Now we multiple
1 Pizza * 17.50 = 17.50
4 soda * 1.25 = 5
2 salad * 1.75 = 3.50
Now we add
17.50 + 5 = 22.50 + 3.50 = $26.00
Now lastly, we divide by 4 since there are 4 friends
26/4 = 6.5
Giving us a answer of $6.50
