PLEASE HELP ME!!!! ITS REALLY URGENT!

Answer:

Step-by-step explanation:

Given that:

a) n³

The first 4 terms are;

let assume n = 1

1³ = 1

if n = 2

2³ = 8

if n= 3

3³ = 27

if n = 4

4³ = 64

So, the sequence is 1, 8, 27, 64

The tenth term of this sequence is: 10³ = 1000

b)

2n²

if the first term is 1

then 2(1)² = 2

if n = 2

2(2)² = 8

if n = 3

2(3)² = 18

if n = 4

2(4)² = 32

So, the sequence is 1, 8, 18, 32

The tenth term will be 2(10)² = 200

The amount of gallons of gas that can be bought with $12 is 2.64 gallons.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

Cost of gas per gallon = $4.55

This can be written as,

1 gallon = 4.55

Multiply 12/4.55 on both sides.

12/4.55 gallons = 12/4.55 x 4.55

2.64 gallons = 12

This means,

2.64 gallons for $12.

Thus,

2.64 gallons can be bought for $12.

Find the inverse.

Answer:

Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Step-by-step explanation:

Let [tex]x[/tex] denote the number of rafts seating 3 people and [tex]y[/tex] the number of rafts seating 5 people. The total number of rafts is 13, so [tex]x+y=13[/tex]. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so [tex]3x+5y=53[/tex].

It's always a good idea to put these equations under each other:

[tex]\left \{ {{x+y = 13} \atop {3x+5y=53}} \right.[/tex]

We can subtract the first equation three times from the second one to obtain [tex](3x+5y)-3(x+y) = 53 - 3(13)\\3x-3x + 5y - 3y = 53 - 39\\2y = 14\\y=\frac{14}{2} = 7[/tex]

Now, substitute this found value for [tex]y[/tex] into [tex]x+y = 13[/tex] and we see that [tex]x=6[/tex]. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.

Answer:

The two angles are 10 degrees and 170 degrees.

Step-by-step explanation:

Supplementary angles add up to 180 degrees.

Let the angle be called "x", and the supplementary angle be called "180-x"

Converting words to math: x-160=180-x

Add x to both sides: 2x-160=180

Simplify: 2x=20

Divide by 2: x=10

Step-by-step explanation:

Okay so the distance between Tom and Jaime is the height of the triangle (South is directly down) (A=15 yards)

The distance between Tom and Ladonna is the base of the triangle (since Ladonna is west of Tom) (B is unknown)

The hypotenuse is the distance between Jaime and LaDonna (C=25 yards)

1. So 15^2 plus b^2 equals 25^2

2. 225 plus b^2 equals 625

3. Subtract 225 from both sides (b^2=400)

4. Find the square root of both sides.
