Ok so this is the first page
1.
78 pizzas. 20% of 65 is 13. Add that to 65 and you get 78 pizzas.
It is a 1.08% decrease. When you divide 65/60 you get 1.08. Im not 100% sure about this one

2.
Online store=$208 and the superstore=$224
The difference is $16 so it would be cheaper to get it at the online store

3.
It is $4000. For the first year you would multiply $20,000 by 5% which is 20000*.05=1000. Then multiply 1000 by 4 years to get $4,000
Instead of multiplying the 1000 by 4, multiply by 2 to get 2000. Subtract 4000-2000 to get 2000. You saved $2,000

Samantha is looking to determine the amount of interest that she will pay on her 4.7% , $40,000 loan over its 15 -year term. The

AysviL [449]

Answer:

The total amount of interest Samantha will pay=$40,842.47

Step-by-step explanation:

Step 1: Determine expression of total interest amount to be payed

The expression for the total interest amount to be payed inclusive of interest is given by;

A=P(1+r/n)^(nt)-P

where;

A=total amount of interest to be payed

P=principal loan amount

r=annual interest rate

n=number of compounding periods in a year

t=number of years

In our case;

P=$40,000

r=4.7%=4.7/100=0.047

n=12

t=15 years

replacing;

A=40,000(1+0.047/12)^(12×15)-40,000

A=40,000(1.00392)^180-40,000

A=40,842.46821

The amount rounded of to the nearest cents=1/100=0.01, round off to the nearest 2 decimal places=40,842.47

The total amount of interest Samantha will pay=$40,842.47

An equation in the form ax2+bx+c=0 is solved by the quadratic formula. The solution to the equation is shown below.x=−7±√ "572"

jolli1 [7]

Answer:

B: a = 1, b= 7, c = -2

Step-by-step explanation:

<u>Quadratic Formula</u>

$x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0$

Given:

$x=\dfrac{-7\pm\sqrt{57}}{2}$

Comparing the terms of the given x-value with those of the quadratic formula:

$\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}=\dfrac{-7\pm\sqrt{57}}{2}$

Therefore:

$2a=2 \implies a=1$
$b = 7$
$b^2-4ac=57$

Using the found values of a and b to solve for c:

$\implies b^2-4ac=57$

$\implies (7)^2-4(1)c=57$

$\implies 49-4c=57$

$\implies -4c=57-49$

$\implies -4c=8$

$\implies c=-2$

In summary: a = 1, b = 7, c = -2

$\implies x^2+7x-2=0$

Therefore, <u>option B</u> is the correct solution.
