Ur amazing if u understand bearings
Sam's "bearing" is simply the direction in which he's moving, which is the angle made with due East.
From point A to point B, his bearing is 335°, and from point B to C, his bearing is 45°. In both cases, the angle is made with due East from the second point. See the sketch for a rough approximation of this. Note that it is not to scale.
To get it into scale, you have to compute the distances traveled along each bearing.
• Moving at 6 km/h for 20 min = 1/3 h would cover a distance of
(6 km/h) • (1/3 h) = 2 km
• Moving at 10 km/h for 15 min = 1/4 h would mean a distance of
(10 km/h) • (1/4 h) = 2.5 km
In your sketch, 1 cm should represent 500 m = 0.5 km, so the arrow from A to B should have a length of 4 cm, while the arrow from B to C should have a length of 5 cm.

It costs 30 dollars per month for a cell phone plus 10 dollars for every GB of data.
Which expression can be used to represent the cost of a cell phone bill when x is the number of GB of data used?
will give brainliest
Answer:
( 10 × x ) + 30
Step-by-step explanation:
This equation would represent the phone bill because you would have to multiply the GB (x) by 10 before adding it to 30 to find the total amount of money.
plz mark me brainliest if correct
The cost of cell phone is represented by expression, [tex]C=10x+30[/tex]
Total cost :It is given that,
It costs 30 dollars per month for a cell phone plus 10 dollars for every GB of data.
Let us consider that x is the number of GB of data used.
The cost of cell phone is represented by,
[tex]C=30+(10*x)\\\\C=10x+30[/tex]
Thus, the cost of cell phone is represented by expression, [tex]C=10x+30[/tex]

Roger restores vintage automobiles. The number of automobiles Roger has restored, f, after n number of years can be described by the equation f(n)=2+5n. What is the rate of change in this situation?
Answer:
The change of rate of the situation is 5.
Step-by-step explanation:
Given f(n) = 2 + 5n. The rate of change is still the same as the slope of the equation. We know that the equation of a line is given as:
f(x) = y = mx + c where m is the slope. In our given equation, f(n) = 2 + 5n = 5n + 2, we see that m = 5 which is our slope.
Therefore, the change of rate of the situation is 5.

A total of 754 tickets were sold for the school play. They were either adult tickets or student tickets. There were 54 more tickets sold than adult tickets. How many adult tickets were sold?
Answer:
Answer: 350
Step-by-step explanation:
Explanation:
a = adult tickets
s = student tickets
║ a + s = 754
║s = a + 54
Plug s = a + 54 into a + s = 754
a + (a + 54) = 754
a + a + 54 = 754
2a + 54 = 754
2a = 754 - 54
2a = 700
a = 350
Directions: Determine how much Marco would be paid
for 10 weeks work.
Marco is initially paid $75 per week and then 2.5%
more each week than the previous week.
Answer:
766.87 is how much he is paid in all.
Step-by-step explanation:
2.5% of 75 is 1.875. 1.875 times 9 is 16.875. 75 times ten is 750. add together to get the whole.
In 10 weeks she will be paid a total of $840 with 2.5% more each week.
What are arithmetic and geometric sequence?An arithmetic sequence is a set of numbers in which every no. next to the previous number has the same common difference
d = aₙ - aₙ₋₁ = aₙ₋₁ - aₙ ₋₂.
In a geometric sequence numbers are written in the same constant ratio(r).
It means every next number is a multiple of a common constant and the previous number.
r = aₙ/aₙ₋₁ = aₙ-₁/aₙ₋₂.
Given, a = 75 and r = 1.025.
We know the sum of a geometric sequence is Sₙ = a(rⁿ - 1)/(r - 1).
∴ S₁₀ = 75(1.025¹⁰ - 1)/(1.025 - 1).
S₁₀ = 75(1.28 - 1)/(0.025).
S₁₀ = 75(0.28)/0.025.
S₁₀ = 840.
