Please help!Your fixed expenses are $1,151.65/month. You saved 4 months' worth in an emergency fund, investing 25% in a savings
FinnZ [79.3K]
4 x 1,151.65 = 4,606.60 
<span>This is invested in two accounts. Twenty-five percent is invested in savings (4,606.60 x 25% = 1,151.65). The remainder is invested in a CD (4,606.60 - 1,151.65 = 3,454.95) </span>

<span>Interest accrued for savings. *Note: The interest rates given are for a full year, but you want to calculate interest for only 60 days. </span>
<span>1,151.65 x 0.033 x 60/360 = $6.33 </span>
<span>Interest accrued for CD </span>
<span>3,454,95 x 0.043 x 60/360 = $24.76 </span>
<span>Total interest accrued </span>
<span>6.33 + 24.76 = $31.09 </span>

<span>Note: 0.033 and 0.043 = 3.3% and 4.3%. Also, the 360 day year is normally used when doing these types of problems.</span>

The maximum load of a horizontal beam that is supported at both ends varies jointly as the width and the height and inversely as
dezoksy [38]

Answer:

360kg

Explanation:

Here, we want to get the maximum load supported

From the first part of the question, we have it that:

The maximum load g, varies jointly with the width w and the height h, and inversely as the length l between the supports

Mathematically, we have that as:

g\text{ = k }\times\frac{wh}{l}

where k is the proportionality constant

Now, let us get the value of k

We substitute the first set of values as follows:

\begin{gathered} 360\text{ = }\frac{k\times0.1\times0.06}{6} \\  \\ k\text{ = 360,000 }\frac{kg}{m} \end{gathered}

Now, using this value of k, we want to get the value of g

Mathematically, we have that as:

g\text{ = }\frac{360,000\times0.2\times0.08}{16}\text{ = 360 }kg

krok68 [10]

Given :

Monthly practice time , T=35 hours .

This month, he has practiced 8.5 hours in week 1, 12 hours in week 2, and 5.5 hours in week 3.

To Find :

Many more hours of practice time does Jason need to complete .

Solution :

Number of hours he practice in week 1 , t_1=8.5\ hours .

Number of hours he practice in week 2 , t_2=12\ hours .

Number of hours he practice in week 3 , t_3=5.5\ hours .

Now , number of hours left is :

t=T-t_1-t_2-t_3\\\\t=35-(8.5+12+5.5)\ hours\\\\t=8\ hours

Hence , this is the required solution .
