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.

Answers
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.

Ur amazing if u understand bearings
Answers
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.

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?
Answers
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

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?
Answers
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.
