Answer:
Each book cost about $6.20 per book, or in more general terms, $6 per book.
Step-by-step explanation:
If you round the $30.85 total of 5 books to $31 and divide that by 5, you get an average cost of $6.20 per book.
If you need a more general answer, you could round the $30.85 total of 5 books to $30 and divide that by 5, you get an average cost of $6 per book.

Step-by-step explanation:
(-3x/2) - 3 = 3
add 3 to both sides
(-3x/2) = 3
multiply both sides by 2
-3x = 6
divide both sides by -3

A water balloon is launched in the air from a height of 12 feet and reaches a maximum height of 37 feet after 1.25 seconds. Write an equation to represent the height h of the water balloon at time t seconds. Then, find the height of the balloon at 2 seconds.
The height of the balloon is given as h(t) = -16t² + 40t + 12 at 2 seconds, the height is 28 feet
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the water balloon after t minutes, hence:
h(t) = -16t² + vt + h₀
Where h₀ is the initial height = 12 feet and v is the initial velocity, hence:
h(t) = -16t² + vt + 12
The height of 37 feet after 1.25 seconds, hence:
37 = -16(1.25)² + v(1.25) + 12
v = 40 m/s
h(t) = -16t² + 40t + 12
After 2 seconds:
h(t) = -16(2)² + 40(2) + 12
h(2) = 28 feet
The height of the balloon at 2 seconds is 28 feet

A spring with spring constant 380 N/m has a force of 37 Newtons applied to it (stretching it). How much does the spring stretch?
Since a force of 37 N is applied to the spring, the spring stretches by 9.74 cm
To answer the question, we need to know Hooke's law.
What is Hooke's law?This states that the force, F on a stretched spring is directly proportional to its extension, x.
So, F ∝ x
Mathematically, F = kx where k = spring constant
The extension of the spring(How much the spring stretches)Making x subject of the formula, we have
x = F/k
Given that F = 37 N and k = 380 N/m, we have
x = F/k
x = 37 N/380 N/m
x = 0.0974 m
x = 9.74 cm
So, the spring stretches by 9.74 cm

Bond A and C the annual interest rate is 1.126%.
Bond X and Y the annual interest rate is 1.25%.
What is Annual Interest?The interest rate on a credit card is the cost of borrowing money. Interest rates on credit cards are often provided as an annual rate. This is known as the annual percentage rate (APR). You can avoid paying interest on purchases on most cards if you pay your amount in full each month by the due date.
The formula for Bond Coupon Rate
Bond Coupon Rate = Bond's current yield / 100
For bond A and C coupon rate is 7.5%.
For X and Y coupon rate is 8.4%.
Now, Annual Interest Rate
= Bond coupon rate x Bond's Face value
For bond A and C the annual interest rate
= 7.5% of $15
= $1.125
For bond X and Y the annual interest rate
= 8.4% of $15
= $1.26

Answer:

a notebook costs $2.50
a poem costs $1.50
B
he can buy 3 pens (and correspondingly 9 notebooks)
Step-by-step explanation:
x = price of 1 notebook
y = price of 1 pen
4x + 3y = 14.5
5x + 6y = 21.5
let's multiply the first equating by -2 and then add both equations
-8x - 6y = -29
5x + 6y = 21.5
----------------------
-3x 0 = -7.5
x = 2.5 = $2.50
4×2.5 + 3y = 14.5
10 + 3y = 14.5
3y = 4.5
y = 1.5 = $1.50
p = number of pens
n = number of notebooks
n = 3p
p×1.5 + n×2.5 = 27
p×1.5 + 3p×2.5 = 27
(1.5 + 7.5)p = 27
9p = 27
p = 3
