Answer:

= 195y + 130

Step-by-step explanation:

Apply the distributive law a(b + c) =ab + ac

$65\left(3y+2\right)=65\cdot \:3y+65\cdot \:2\\=65\cdot \:3y+65\cdot \:2$

Simplify:

$65*3y+65*2\\195y+130$

The sp of a watch is rs 270,if this watch was sold at 10 %discount from mp what was the mp.

Alexeev081 [22]

Answer:

Rs. 300

Step-by-step explanation:

Given that the watch was sold for 90%.

So, 90% = 270.

We have to find 100%.

To do this, find ten % the. Multiply that by 10.

90%=270

10% = 270/9 = 30

100% = 30 x 10= 300.

Hope this helps

Which expression is equivalent to \root(3)(x^(5)y)

san4es73 [151]

Answer:

$\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}$

Step-by-step explanation:

Given

$\sqrt[3]{x^{5}y}$

Required

The equivalent expression

We have:

$\sqrt[3]{x^{5}y}$

Rewrite as an exponent

$\sqrt[3]{x^{5}y} = (x^{5}y)^\frac{1}{3}$

Open bracket

$\sqrt[3]{x^{5}y} = x^{5*\frac{1}{3}}y^\frac{1}{3}$

$\sqrt[3]{x^{5}y} = x^{\frac{5}{3}}y^\frac{1}{3}$

A group of retailers will buy 104 televisions from a wholesaler if the price is $300 and 144 if the price is $250. The wholesale

const2013 [10]

Answer:

(275,122)

When the price will be $275, the quantity will be 122 televisions.

Step-by-step explanation:

We have been given that a group of retailers will buy 104 televisions from a wholesaler if the price is $300 and 144 if the price is $250.

As the quantity of televisions depends on price of televisions, so our demand curve will pass through points (300,104) and (250,144).

Let us find slope of demand line using slope formula.

$m=\frac{y_2-y_1}{x_2-x_1}$ , where,

$m =\text{Slope of line}$ ,

$y_2-y_1=\text{Difference between two y-coordinates}$ ,

$x_2-x_1=\text{Difference between same x-coordinates of two y-coordinates}$

Upon substituting coordinates of our given points in slope formula we will get,

$m=\frac{104-144}{300-250}$

$m=\frac{-40}{50}$

$m=-\frac{4}{5}$

Let us substitute $m=-\frac{4}{5}$ coordinates of point (250,144) in slope intercept form of equation ( $y=mx+b$ ).

$144=-\frac{4}{5}*250+b$

$144=-4*50+b$

$144=-200+b$

$144+200=-200+200+b$

$344=b$

Upon substituting $b=344$ and $m=-\frac{4}{5}$ we will get equation of our demand line as:

$y=-\frac{4}{5}x+344$

Similarly we will find the equation of supply line using points (225,88) and (315,168).

$m=\frac{168-88}{315-225}$

$m=\frac{80}{90}$

$m=\frac{8}{9}$

Let us substitute $m=\frac{8}{9}$ and coordinates of point (225,88) in slope intercept form of equation ( $y=mx+b$ ).

$88=\frac{8}{9}*225+b$

$88=8*25+b$

$88=200+b$

$88-200=200-200+b$

$-112=b$

Upon substituting $b=-112$ and $m=\frac{8}{9}$ we will get equation of our supply line as:

$y=\frac{8}{9}x-122$

Let us equate both lines to find the point where both lines intersect.

$-\frac{4}{5}x+344=\frac{8}{9}x-122$

$-\frac{4}{5}x-\frac{8}{9}x+344=\frac{8}{9}x-\frac{8}{9}x-122$

$-\frac{4}{5}x-\frac{8}{9}x+344=-122$

$-\frac{4}{5}x-\frac{8}{9}x+344-344=-122-344$

$-\frac{4}{5}x-\frac{8}{9}x=-466$

Let us have a common denominator.

$-\frac{4*9}{5*9}x-\frac{8*5}{9*5}x=-466$

$-\frac{36}{45}x-\frac{40}{45}x=-466$

$\frac{-36-40}{45}x=-466$

$\frac{-76}{45}x=-466$

$\frac{-76}{45}*\frac{45}{-76}x=-466*\frac{45}{-76}$

$x=466*\frac{45}{76}$

$x=6.1315789473684211*45$

$x=275.9210526315789495\approx 275$

Let us substitute x=275 in any of our equation to solve for y.

$y=-\frac{4}{5}*275+344$

$y=-4*55+344$

$y=-220+344$

$y=122$

Therefore, the equilibrium point for the market will be (275,122).

One third of a bird's eggs hatched. If 2 eggs hatched, how many eggs did the bird lay?

Elodia [21]

The bird laid 6 eggs since only 1/3 hatched, one can multiply 2 by 3 to get 3/3 of the eggs which would equal 6.
