Chapter 7 of the Jiuzhang suanshu presents a problem of two linear equations involving acres of land and their respective prices
djyliett [7]

Answer: 33.041666

Step-by-step explanation:

Given: The translated equation : 300x+y = 10000

To find the value of x if y = 87.5, we need to substitute the value of y in the given translated equation, we will get

300x+87.5 = 10000

Subtract 87.5 from both the sides , we get

300x=9912.5

Now, divide 300 on both the sides, we get

x=\frac{9912.5}{300}\\\\\Rightarrow x=33.041666666

densk [106]

Answer:  There are 177100 possible groups.

Step-by-step explanation:

Given: Total employees = 25

Number of  employees  wants to choose = 6

The combination of n things taken r at a time is given by:-

^nC_r=\frac{n!}{r!(n-r)!}

Put n = 25 and r= 6, we get

^{25}C_6=\frac{25!}{6!(25-6)!}\\\\=\frac{25\times24\times23\times22\times21\times20\times19!}{6!19!}\\\\=177100

Hence, there are 177100 possible groups.

Questione Simplify Cosa + 2Cos(a +240")​
melamori03 [73]

Step-by-step explanation:

\cos(a)  + 2 \cos(a + 240)

\cos(a)  + 2 \cos(a)  \cos(240)  -  \sin(a)  \sin(240)

\cos(a)  + 2( -  \frac{ \cos(a) }{2}  +   \frac{ \sqrt{3} }{2}   \sin(a) )

\cos(a)  -  \cos(a)  +  \sqrt{3}  \sin(a)

\sqrt{3}  \sin(a)

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.
