Leslie tunes a guitar with 6 strings and a piano with 37 times as many strings.
How many strings did the piano have?
Choose 1 answer:
(Choice A)
The piano has 422 strings, because 37×6=422.
(Choice B)
The piano has 222 strings, because 37×6=222.
(Choice C)
The piano has 6 strings, because 37÷6=6 remainder 1.

a) The nth term of a sequence is 2n - 3
Work out the first three terms of the sequence.
[2]
b) Write down an expression for the nth term of the following sequence.
9, 14, 19,
[2]
24,
BH
Answer:
(a) [tex]Sequence: -1, 1, 3[/tex]
(b) nth term: [tex]T_n = 4+ 5n[/tex]
Step-by-step explanation:
Solving (a)
Given
[tex]T_n = 2n - 3[/tex]
The first 3 terms.
When n = 1
[tex]T_1 = 2*1 - 3[/tex]
[tex]T_1 = 2 - 3[/tex]
[tex]T_1 = -1[/tex]
When n = 2
[tex]T_2 = 2*2 - 3[/tex]
[tex]T_2 = 4 - 3[/tex]
[tex]T_2 = 1[/tex]
When n = 3
[tex]T_3 = 3*2 - 3[/tex]
[tex]T_3 = 6 - 3[/tex]
[tex]T_3= 3[/tex]
So, the first three terms are:
[tex]Sequence: -1, 1, 3[/tex]
Solving (b)
Given
[tex]Sequence: 9,14,19,24[/tex]
Required
The nth term
The sequence is arithmetic.
So, first calculate the common difference (d)
[tex]d = 14 - 9[/tex]
[tex]d = 5[/tex]
The nth term is then calculated as:
[tex]T_n = a + (n - 1) * d[/tex]
Where
[tex]a =First\ term[/tex]
So:
[tex]a = 9[/tex] and [tex]d = 5[/tex]
[tex]T_n = 9 + (n - 1) * 5[/tex]
[tex]T_n = 9 + 5n - 5[/tex]
Collect like terms
[tex]T_n = 9 - 5+ 5n[/tex]
[tex]T_n = 4+ 5n[/tex]
Brock Lesnar is standing next to his time machiner when he spots a pterodactyl soaring through the air. Brock Lesnar wants that pterodactyl for his trophy room. So he sets up his range finder and finds that the direct distance from the gun to the pterodactyl is 1000 yds. His angle of elevation to the pterodactyl is 17 degrees if Brock Lesnar his the pterodactyl. How far will he have to drag the dead pterodactyl along the ground to get it back to this time machine.
a. 1046 yds
b. 306 yds
c. 956 yds
d. 400 yds
e. 292 yds
Answer:
C. 956 ydsStep-by-step explanation:
Use cosine to solve this:
cos 17° = x / 1000x = 1000 cos 17°x = 956 ydsCorrect choice is C
Step-by-step explanation:
➡cos17=x/1000
using cross multiplication➡x=1000×cos17
➡x=956yards
Which of the following equations, represents the line with a slope of -2/5 and a y-intercept of 2?
1) y = -2/5x -2
2) y = -2/5x + 2
3) y = 2/5x - 2
4) y = 2/5x + 2
Answer:
2)
Step-by-step explanation:
Y intercept means x=0.
y=mx+c
m is the slope
y=-2/5x+c
Y intercept is 2
y=(-2/5)0+c =2

Find the x and y intercepts of 4x - 5y = 40
Is this correct and can someone explain why??
Answer:
no, the correct answer is D.
Step-by-step explanation:
for the x-intercept you would first add 5y to both sides giving you 4x=5y+40. then you would divide both sides by 4, so the final equation would be x=5/4y+10.
for the y-intercept you would subtract 4x from both sides, making -5y=-4x+40. then you would divide both sides by -5, making the final equation y=4/5x-8.
6. What is the area of he trapezoid? Help Please
Answer:
It’s G. 330 m^2
Step-by-step explanation:
The formula for a trapezoid is (a+b)/2 times h.
So a is base one and b is base two and the h is the height.
So it would be like (19+41)/2 X 11 then you would get
60/2 X 11
30 X 11 equals 330

Answer:
B
Step-by-step explanation:
First we find out over how many years the growth happened, from 1985 to 2020, that's 35 years.
In 1985 the club had 23,000 members, and it grew at an ave. rate of 5% each year. So, to find out 5% of 23,000 we can divide it by 100 to find 1% and then multiply by 5.
23,000 / 100 = 230 now 230 times 5 is 1150, to check our work we can multiply 1150 by 20 because it is 5% to get 100% and it is 23000 so we are on track so far. Now over the span of 35 the club grew by 1,150 each year, so, 1150 times 35 is 40,250 and if we add that to 23,000 we get 63,250. Round to the nearest thousand which would be
B. 78,000 but I may have went about solving exponential growth wrong but if this is the answer you have been getting there you go.

HELP HELP HELP HELP FIND THE VALUE OF X
Answer:
x=9
Step-by-step explanation:
The sum of all three angles inside a triangle is always 180 and the small square in the bottom left corner means that that is a 90 degree angle.
90+5x+5x=180
add the x values together
90+10x=180
subtract 90 from both sides
10x=90
divide both sides by 10
x=9

Which statement describes the graph of y = 7?
a: A horizontal line with no "run" and infinite "rise"
b: A horizontal line with no "rise" and infinite "run"
c: A vertical line with no "run" and infinite "rise"
d: A vertical line with no "rise" and infinite "run
Answer:
b. A horizontal line with no "rise" and infinite "run"
Step-by-step explanation:
since y = 7, y will always equal 7 no matter what the x value is, so it has no rise, or increase in y value. But it doesn't say anything about the x value, so it infinitely increases. The answer is b. A horizontal line with no "rise" and infinite "run"

A computer game was originally priced at $59.99. It was marked down 15%. Then it was moved to a clearance rack marked "Take an additional 50% off the lowest marked price." What was the final price of the computer game?
Answer:
25.50 is the final price
Step-by-step explanation:
First find the new price at 15% off
59.99 * 15%
59.99 * .15
9.00
Subtract 9 dollars from the price
59.99-9.00
50.99
Now take 50% off
50.99 * 50%
50.99*.50
25.50
50.99-25.50
25.50
Karen purchased a used vehicle that depreciates under a straight-line
method. The initial value of the car is $4000, and the salvage value is $400. If
the car is expected to have a useful life of another 6 years, how much will it
depreciate each year?
Answer:
2400
Step-by-step explanation:
because it goes down 400 each year
Karen expects the vehicle to depreciate by 600 each year.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Now, It is expected to depreciate from 4000 to 400 in 6 years.
Hence, The depreciation per year is the ratio is,
⇒ Depreciation per year = (Total depreciation) / (Number of years)
Hence, The total depreciation is the change in value, so the depreciation per year is
⇒ (4000 - 400)/6
= 3600 / 6
= 600
Thus, Karen expects the vehicle to depreciate by 600 each year.
