Answer: Sales price of the item would be approximately $2.

Step-by-step explanation:

Since we have given that

List price of the item = $2.89

Rate of decline = 31%

So, Amount reduced by

\frac{31}{100}\times 2.89\\\\=0.31\times 2.89\\\\=\$0.8959

So, Sales price of the item will be

2.89-0.8959\\\\=\$1.9941\\\\=\$2

Hence, Sales price of the item would be approximately $2.

Find the value of each variable
kondaur [170]

Answer:

The correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Step-by-step explanation:

Points to remember

The angles of a right angled triangle, 30°, 60° and 90° then sides are in the ratio, 1: √3 : 2

<u>To find the value of variables</u>

From the figure we can see 2 right angled triangle with angle 30, 60 and 90

we get, d= 5 then b = 5√3

b = 5√3  the c = 5√3 * √3 = 15

and a = 2 * 5√3 = 10√3

Therefore the correct answer is option C

a = 10√3, b = 5√3, c = 15 and d = 5

Simplify: (4 /5 + 6/ 25 ) X (8/ 9 + −8 /7 )​
Westkost [7]

Answer: -416/1575

Step-by-step explanation:

\frac{4}{5}=\frac{20}{25} \implies \frac{4}{5}+\frac{6}{25}=\frac{26}{25}\\

\frac{8}{9}=\frac{56}{63}\\\\-\frac{8}{7}=-\frac{72}{63}\\\\\implies \frac{8}{9}-\frac{8}{7}=-\frac{16}{63}

\frac{26}{25} \times -\frac{16}{63}=-\frac{416}{1575}

Suppose a triangle has two sides of length 32 and 35, and that the angle between these two sides is 120. What is the length of t
Naily [24]
You would need to use the Law of Cosines.

c^2=a^2+b^2-2abcosC

In this case:

c=√(32^2+35^2-2*32*35cos120)

c≈58.04 units
