hence, l = 11 and w = 4

hence, 4*11 = 44 square units.

A sum of money amounting to $4.15 consists of dimes and quarters. If there are 28

anastassius [24]

Answer:

there are 9 quarters and 19 dimes

Step-by-step explanation:

Let x be the number of dimes and y the number of quarters

-dimes: 0.1x

-quarters: 0.25y

-the total amount of coins : x + y = 28

=> x = 28 - y

We have the equation:

0.25y + 0.1x = 4.15

0.25y + 0.1(28 - y) = 4.15

0.25y + 2.8 - 0.1y = 4.15

0.15y = 1.35

y = 9

x = 28 - y

= 28 - 9

= 19

Lin solved the equation 8(x-3)+7=2x(4-17) incorrectly. Find the errors in her solution. What should her answer have been?

Irina-Kira [14]

Answer: The correr solution is $x=\frac{17}{34}$

Step-by-step explanation:

Since the steps in Lin's solution are not shown, we are not able to find her erros. However, we can solve it step by step and find the correct result:

$8(x-3)+7=2x(4-17)$

Firstly, in the left part of the equation we have to multiply $8$ by the numbers inside the parenthesis; and in the right side we have to solve first what is inside the parenthesis:

$8x-24+7=2x(-13)$

Adding similar terms in the left side and multiplying $2x$ by the number inside the parenthesis in the right side:

$8x-17=-26 x$

Isolating $x$ :

$x=\frac{17}{34}$ This is the correct solution

Nolan Walker decided to buy a used snowmobile since his credit union was offering such low interest rates. He borrowed $2,700 at

stealth61 [152]

Using the formula for simple interest, it is found that he paid $119.87 in interest.

The<u> simple interest formula</u> is given by:

$E = PIt$

E is the amount of interest earned.
P is the principal(the amount of money invested).
I is the interest rate(yearly, as a decimal).
t is the time, in years.

In this problem:

Borrowed $2,700, thus $P = 2700$
Interest rate of 3.5%, thus $I = 0.035$
From December 26, 2019 to February 21, 2021, there were 423 days, thus the time in years is $t = \frac{423}{365} = 1.2685$
