Vsevolod [243]3 years ago

Step-by-step explanation:

3q - 1 = 3(1) - 1 = 2

3q -1 = 3(2)- 1= 5

10/p = 2 10/p = 5

p= 5 p= 2 (5-2=3, so 10/p is correct)

q=5, 3(5) -1 = 14

10/p = 14

p = 0.71??

You have a part time job in your junior year of high school. You need to borrow $2,000 to purchase a used car to drive to work.
VARVARA [1.3K]

Answer:

$149.66

Step-by-step explanation:

Step 1

Calculate Total Amount payable to the bank using compound interest

Total Amount payable (A) =

P(1 + r/n)^nt

P = Principal = $2000

r = Interest rate = 9% = 0.09

n = compounding interest = quarterly = 4

t = time in years = 2

Total Amount payable

= 2000(1 + 0.09/4)^0.09 × 2

A = $ 2,389.66

Interest = A - Principal

= $ 2,389.66 - $ 2,000.00

I (interest) = $ 389.66

Step 2

Calculate the Total amount payable to his uncle using simple interest.

Total Amount (A) = P(1 + rt)

P = Principal = $2000

r = Interest rate = 6% = 0.06

t = time in years = 2

A = 2000(1 + 0.06 × 2)

A = $2,240

A - Principal

= $ 2,240 - $ 2,000.

I (interest) = $240

Step 3

The amount of money you will save by borrowing the money from your uncle is calculated as:

Amount payable to the bank - Amount payable to your uncle

= $ 2,389.66 - $2,240

= $149.66

Therefore, the amount of money you will save by borrowing the money from your uncle is $149.66

</span>
Let's sum all up:
1yd 2ft 6in + 2yd 1ft 5in + 4yd 2ft 8in

Sum inches:
6 + 5 + 8 = 19 in
12 in = 1 ft
19 in = 1ft 7in

Sum feet:
2 + 1 + 2 + 1(from inches) = 6 ft
3ft = 1yd
6ft = 2y

Sum yards:
1 + 2 + 4 + 2(from feet) = 9 yd

15 POINTS - What is the value of the expression when y=2? See image.
artcher [175]

Answer:

6

Step-by-step explanation:

The given expression is;

\frac{2-y}{4+y}+\frac{3(y+2)}{y}

When y=2, the expression becomes;

\frac{2-2}{4+2}+\frac{3(2+2)}{2}

This simplifies to;

\frac{0}{6}+\frac{3(4)}{2}

0+3(2)

Multiply to get;

0+6=6

The value of the expression when y=2 is 6.
