7. An aircraft flies 400 km from a point O on a bearing of 025°
and then 700 km on a bearing of 080° to arrive at B.
a) How far north of O is B?
b) How far east of O is B?
Answer:
484 km north858 km eastStep-by-step explanation:
You want the distances north and east of the origin that a plane ends up after flying 400 km at a bearing of 25°, then 700 km at 80°.
Coordinate transformationFor some distance r and bearing angle θ, the (north, east) coordinates will be ...
(north, east) = (r·cos(θ), r·sin(θ))
ApplicationFor the trip at hand, the final coordinates of the plane are ...
a)Distance north = (400 km)cos(25°) +(700 km)cos(80°)
= 362.52 km +121.55 km = 484.07 km
B is about 484 km north of O.
b)Distance east = (400 km)sin(25°) +(700 km)sin(80°)
= 169.05 km +689.37 km = 858.41 km
B is about 858 km east of O.

Here,
Alvira and Barry Gomez purchased a home priced at $280,000.
They put down 40%.
We have to find down payment.
And, Amount of the mortgage loan.
What is Down payment?
A sum of money that a buyer pays in the early stages of purchasing an expensive good or service is called down payment.
Now,
Alvira and Barry Gomez purchased a home priced at $280,000.
They put down 40%.
Hence, The down payment = $280,000 x 40%
= $280,000 x 40 / 100
= $112,000
And, Amount of the mortgage loan = Total amount - Down payment
= $280,000 - $112,000
= $168,000
Therefore, The down payment is $112,000.
And, Amount of the mortgage loan is $168,000.

Write a function g whose graph represents the indicated transformation of the graph of f.
f(x) = 3x ; translation 5 units up
the translated function is g(x) =
Answer:
g(x) = 3x +5
Step-by-step explanation:
You want the function that results from translating f(x) = 3x upward by 5 units.
TranslationThe y-coordinate of a point tells how far above the x-axis it is. Adding 5 to the y-coordinate will move that point 5 units farther above the x-axis, which is to say 5 units upward.
The y-coordinate of a point on a graph is the value of the function of the x-coordinate of that point. That is, each point is (x, f(x)). If we want to translate that point 5 units upward, we add 5 to the function value:
(x, f(x) +5) . . . . . graph translated 5 units up
Using the given definition of f(x), this becomes ...
(x, 3x +5)
The translated function is defined as g(x), so we have ...
(x, g(x)) = (x, 3x +5)
or ...
g(x) = 3x +5

Whitney buys two submarine sandwiches for an after-school party. One sandwich is 45 inches long and the other sandwich is 20 inches long. Whitney wants to cut servings of the same length from both sandwiches, without having any sandwich left over. What is the greatest length serving that Whitney can cut?
Answer:
5 inches
Step-by-step explanation:
Whitney wants the greatest length that is an even divisor of both 45 inches and 20 inches.
Greatest common factorThe length Whitney is looking for is called the "greatest common divisor" (GCD) or "greatest common factor" (GCF) of the two numbers 45 and 20. There are a couple of different ways this can be found.
FactoringThe prime factors of the two numbers are ...
45 = 3×3×5
20 = 2×2×5
The only factor common to the two products is 5. It is the greatest common factor.
Whitney can cut lengths of 5 inches.
Euclid's algorithmAnother way to find the GCD is to use Euclid's algorithm. That has you ...
Divide the larger number by the smaller and keep the remainder.If the remainder is not zero, replace the larger number with it and repeat.If the remainder is zero, the smaller number is the GCD.Using this algorithm, we have ...

If x varies directly as y and when x = 5, y = 20. Find the relationship between x and y.
the relationship between x and y when x varies directly is 4 x = y.
We know that when x varies directly with y, then:
x = k y
Now, we have x = 5 and y = 20
Substituting the values in the expression, we get that:
5 = 20 k
k = 5 / 20
k = 1 / 4
So, we get the relation as:
x = 1 / 4 y
4 x = y
Therefore, the relationship between x and y when x varies directly is 4 x = y.

Please see the graph attached.
What is compound inequality?A compound inequality has two inequality statements joined either by the "or" or “and.”
We have,
6x+2y<12 or x-6y>6
We can graph each inequality.
And we also need to see the intersection between the inequalities.
Let,
6x + 2y = 12____(1)
x - 6y = 6_______(2)
From (1)
x = (12 - 2y ) / 6 put in (2)
(12 - 2y) / 6 - 6y = 6
2 - 1/3y - 6y = 6
2 - 6 = (1/3)y + 6y
-4 = 19y / 3
y = -12 / 19
y = - 0.63 put in (1)
6x + 2 x (-0.63) = 12
6x = 12 + 1.26
x = 13.26 / 6

At a certain company, the average starting salary s for a new worker is $25,000. The actual salary has an absolute deviation of at most $1800. Write and solve an inequality to find the range of the starting salaries.
The range of the salary will be the closed interval [23,200, 26,800].
What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
A new hire at one organization may expect to get an average beginning pay of $25,000 per year. The absolute divergence from the real compensation is no more than $1800.
Let 'x' represent the actual salary. Then the inequality is given as,
|x - 25,000| ≤ 1800
- 1,800 ≤ x - 25,000 ≤ 1,800
25,000 - 1,800 ≤ x ≤ 25,000 + 1,800
23,200 ≤ x ≤ 26,800
The range of the salary will be the closed interval [23,200, 26,800].

After a person gets a 2% raise in salary, the new salary is $11874. What was the original salary?
Answer:
Original salary was $11641.17Step-by-step explanation:
Let the initial salary be x.
Set equation and solve for x:
x + 2% of x = 11874x + x*2/100 = 11874x + 0.02x = 118741.02x = 11874x = 11874/1.02x = 11641.17 (rounded to the nearest cent)
Answer:
The original salary is $11641.18.
Step-by-step explanation:
The equation will be,
→ x + (x × 2)/100 = 11874
Now the original salary will be,
→ x + (x × 2)/100 = 11874
→ x + 0.02x = 11874
→ 1.02x = 11874
→ x = 11874/1.02
→ x = 11641.1764706
→ [ x = 11641.18 ]
Hence, original salary is $11641.18.

What are parallelograms?A parallelogram is a simple (non-self-intersecting) quadrilateral with two pairs of parallel sides in Euclidean geometry. A parallelogram's opposite or facing sides are of equal length, and its opposite angles are of equal measure. The congruence of opposite sides and angles is a direct result of the Euclidean parallel postulate, and neither condition can be proven without resorting to the Euclidean parallel postulate or one of its equivalent formulations.The net is made up of six parallelograms, each representing one of the box's faces.
Four rectangular faces with dimensions of 6 ft × 4 ftThe other two faces are square in shape, with side lengths of 4 feet.The area represented by the net can be used to estimate how much cardboard Jayden will need to make the box.
The calculations are as follows:
Rectangular faces: length × height = 6 ft × 4 ft = 24 ft²Square faces: side length² = (4 ft)² = 16 ft²So, our rectangles and two squares:
4 × 24 ft² + 2 × 16 ft² = 96 ft² + 32 ft² = 128 ft².Therefore, Jayden needs (C) 128 ft² cardboard to make a box.

What is perimeter?The perimeter of a shape is the sum of the lengths of all its edges. For example, a triangle has three edges, so its perimeter is equal to the sum of those three lengths.
The perimeter of a square can be easily calculated if one side and all other sides are given as being the same length; for example, a square with sides measuring 5 inches long has a perimeter of 20 inches because 5 x 4 = 20. By multiplying the sum of the length and width by two, one can determine a rectangle's perimeter.

A theater charges $8 for main-floor seats and $4 for balcony seats. If all seats are sold, the ticket income is $5200. At one show, 25% of the main-floor seats and 50% of the balcony seats were
income was $1800 How many seats are on the main floor and how many are in the balcony?
By solving a system of equations we can see that there are 400 main-floor seats and 500 balcony seats.
How many seats are on the main floor and how many are in the balcony?Let's define the two variables:
x = number of seats on the main-floor.y = number of balcony seats.We know that if all the seats are sold, then the total income is $5,200, we can write the equation:
x*$8 + y*$4 = $5,200
And if 25% of the main-floor and 50% of the balcony seats are sold, then we get an income of $1800, then we can write:
0.25*x*$8 + 0.5*y*$4 = $1,800
x*$2 + y*$2 = $1,800
So we have a system of equations:
x*$8 + y*$4 = $5,200
x*$2 + y*$2 = $1,800
If we subtract twice the second equation for the first one we get:
(x*$8 + y*$4) - (x*$2 + y*$2) = $5,200 - 2*$1,800
x*$4 = $1,600
x = $1,600/$4 = 400
So there are 400 seats on the main-floor.
Using the first equation we can find:
x*$8 + y*$4 = $5,200
400*$8 + y*$4 = $5,200
$3,200 + y*$4 = $5,200
y*$4 = $5,200 - $3,200 = $2,000
y = $2,000/$4 = 500
So there are 500 balcony seats.
