Mrs. Jones bought three 2-kilogram packages of flour. How many grams of flour did she buy?

Makovka662 [10]

It is given that, Mrs. Jones bought three 2-kilogram packages of flour.

And

$1 kilogram = 1000 grams$

And three 2 -kilogram packages means she bought 6 kilogram flour .

So we need to convert 6 kilogram flour into grams.

If,

$1 kilogram = 1000grams, \\ than, \\ 6 kilograms = 6*1000=6000 grams$

So she bought 6000 grams of flour .

Triangles SLB and DOG are similar with <S=<D and <L =<O. If SL, LB and SB are 3,4,5 respectively and DO=5 find OG an

xeze [42]

All the side measures of ΔDOG will have the same relationship to their corresponding ΔSLB measures that DO has to SL.

OG/LB = DO/SL
OG/4 = 5/3
OG = 20/3

DG/SB = DO/SL
DG/5 = 5/3
DG = 25/3

In summary,
OG = 20/3 = 6 2/3
DG = 25/3 = 8 1/3

What is the value of ?A. 7.5 B. 17.5 C. 60.5 D. 76.5

REY [17]

Answer:

76.5

Step-by-step explanation:

Recall that for any positive integer n

n! = 1*2*3*4*...*n

For example

5! = 1*2*3*4*5 = 120

$\sum_{n=2}^6\frac{(n-1)!}{2}=\frac{(2-1)!}{2}+\frac{(3-1)!}{2}+\frac{(4-1)!}{2}+\frac{(5-1)!}{2}+\frac{(6-1)!}{2}=\\\\=\frac{1!}{2}+\frac{2!}{2}+\frac{3!}{2}+\frac{4!}{2}+\frac{5!}{2}=\frac{1}{2}+\frac{1*2}{2}+\frac{1*2*3}{2}+\frac{1*2*3*4}{2}+\frac{1*2*3*4*5}{2}=\\\\=\frac{1}{2}+1+3+12+60=\boxed{76.5}$
