Craig is considering four loans. Loan L has a nominal rate of 8.254%, compounded daily. Loan M has a nominal rate of 8.474%, com
nalin [4]
<span>In order for you to be able to determine on which is the best effective interest rate, we need to compute each interest and see on how much would it accrue after it matures. The formula to use is the compound interest formula which is A=P(1+r/n)^nt, wherein A is the amount of due including the interest, P as the principal, r as the interest rate, n as the number of times it would be compounded per year and t as the number of years it would be loaned. To reassign the formula with each given interest rate, and assuming that the amount to be loaned would be 1,000 and the number of years it would be loaned will be 5 years, the amount due after 5 years for the 8.254% compounded daily will be 1,510.82, for the 8.474% compounded weekly will be 1,527.03, for the 8.533% compounded monthly will be 1,529.80, for the 8.604% compounded yearly will be 1,510.88. The best effective interest rate offer would be the 8.254% compounded daily.</span><span />

Lin knows that there are 4 quarts in a gallon. She wants to convert 6 quarts to a gallon, but cannot decide if she should multip
defon

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

4\text{ quarts}=1\text{ gallon}

1\text{ quarts}=\dfrac{1}{4}\text{ gallon}

6\text{ quarts}=\dfrac{6}{4}\text{ gallon}

Here, 6 quarts is equal to \dfrac{6}{4} gallon. It means we need to multiply 6 by 4 in 4\text{ quarts}=1\text{ gallon} to find the answer.

Which statements are true about the graph of y &lt; Two-thirdsx + 1? Check all that apply. The slope of the line is 1. The line
Marina CMI [18]

The answer would be:

The x-intercept of the boundary line is (-3/2, 0).

The area below the line is shaded.

The slope of the line should be 2/3. The area below the line shaded because the function using y<.....

Coordinate 2,3 doesn't fulfill the function. 

y < 2/3x + 1

3 < 2/3(2)+1

3< 4/3+1

3< 2.3    ---->false

X intercept is when the y variable is zero. If you put it to the equation

 y = 2/3x + 1

0= 2/3x+1

2/3x= -1

x= -3/2

Drainage tubing comes in large rolls. At your hardware store, you cut tubing to the lengths the customers want. You also provide
MrRa [10]

Answer: \frac{1}{36}\pi L

Step-by-step explanation:

The formula for calculate the volume of a cylinder is:

V=\pi r^2h

Where "r" is the radius and "h" is the height.

Make the conversion from inches to feet. Since 1\ ft=12\ in,you get:

(2\ in)(\frac{1\ ft}{12\ in})=\frac{1}{6}\ ft

So in this case you  can identify that:

r=\frac{1}{6}\\\\h=L

Then, substituting them into the formula and simplifying you get:

V=\pi(\frac{1}{6})^2L\\\\V=\frac{1}{36}\pi L

Therefore, the expression for the volume of L feet of drainage tubing, in cubic feet is:

\frac{1}{36}\pi L
