Answer:

63/5 or 12 (3/5)

Step-by-step explanation:

It is 8 whole (1 ÷ 5) plus 4 whole (2 ÷ 5)

So,we can write it as 8 (1/5) + 4 (2/5)

Then we will take those mixed fractions to improper fractions by using the rule of multiplication.

8 will be multiplied by 5 and then the value will be added to 1. Same rule will be applied for the second fraction.

(41÷5) + (22÷5)

Now we will take L.C.M. (Least common multiple) for both denominators 5 and 5. The L.C.M of 5 and 5 = 5

(41 + 22)/5

= 63/5

It is the answer. Also we can make this improper fraction into mixed fraction by dividing the whole number by 5.

12 (3/5)

How much would $300 invested at 4 percent interest compounded monthly be worth after 8 years round your answer to the nearest ce

ratelena [41]

We will use the equation $A(t)=P(1+ \frac{r}{n})^{(n)(t)}$ , where P is the initial amount invested, r is the interest rate in decimal form, n is the number of times in a year the money is compounded, and t is the number of years the money will be invested. Our P = 300, r = .04, n = 12 (there are 12 months in a year), and t = 8. Filling in accordingly, $A(t)=300(1+ \frac{.04}{12})^{(12)(8)}$ . Simplifying what we can gives us $A(t)=300(1+.00333333)^{96}$ . Doing that addition inside the parenthesis and then raising that number to the 96th power gives us A(t) = 300(1.376395075) so A(t) = $412.92, choice B above.

I need FAST help???????????

Here what do we observe:-

Two opposite side pairs are parallel so they are surely equal.(Generic Quadrilateral rejected)
Two opposite angle pairs are equal (Rhombus and rectangle omitted)

Hence it's a PARALLELOGRAM.
