A recipe requires 1/3 cup of milk for each 1/4 cup of water. How many cups of water are needed for each cup of milk?

raketka [301]

The answer would be B because you have to multiply 1/3 by 3 to get a whole cup. Therefore, you have to multiply 1/4 by 3 also. In this case, the answer would be 3/4. Hope this helps!

If a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month, what

OLEGan [10]

Answer:

$97.15.

Step-by-step explanation:

We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.

We will use interest formula to solve our given problem.

$I=PrT$ , where,

$I=\text{Interest}$ ,

$P=\text{Principal amount}$ ,

$r=\text{Interest rate in decimal form}$ ,

$T=\text{Time}$

Let us convert our given interest rate in decimal form.

$3.35\%=\frac{3.35}{100}=0.0335$

Upon substituting our given values in interest formula we will get,

$I=2,900*0.0335*1$

$I=2,900*0.0335$

$I=97.15$

Therefore, the monthly interest charge at the end of the 1st month will be $97.15.

Given:

<span>The average number of daylight hours each month in Springfield in 2015:

Jan 9.5
Feb 10.5
Mar 12
Apr 13.25
May 14.5
Jun 15
Jul 14.75
Aug 13.75
Sep 12.5
Oct 11.0
Nov 9.75
Dec 9.25

Now, we observe the trend of the monthly hours, it starts with a low value then increases and decreases back to the original value. This represents a parabola with the highest point of 15 hours. </span><span />
