An artist agrees to paint a landscape painting at 0.30 per square inch. if the painting is 13 inches by 17 inches, how much shou

Yuri [45]

We know that
[area of the painting]=13 in* 17 in-----> 221 in²

if an artist painting at
$0.30 per --------------> 1 in²
x$--------------> 221 in²
X=221*0.30------> x=$66.30

the answer is
$66.30

Se quiere cubrir una pared con vidrios de forma triangular. La pared mide 36 m de largo y 9V3 m de alto.

Eddi Din [679]

Based on the dimensions of the wall and the triangular glass, the number of mirrors needed is 215 mirrors.

<h3>What number of mirrors are needed?</h3>

First find the area of the wall:

= 36 x 93

= 3,348 m²

The area of the triangle, assuming it is an equilateral triangle is:

= (√3/4) x 6²

= 15.59 m²

The number of mirrors needed is:

= 3,348 / 15.59

= 215 mirrors

One of the roots of the quadratic equation 4mnx^2 – 6m^2x – 6n^2x + 9mn = 0 (m, n ≠ 0) is a)-3m/2n b)3m/2n c)2m/3n d)-2m/3n

maxonik [38]

Answer:

$B.\ \frac{3m}{2n}$

Step-by-step explanation:

Given

$4mnx^2 - 6m^2x - 6n^2x + 9mn = 0\ (m, n \neq 0)$

Required

Calculate one of the root of the equation

$4mnx^2 - 6m^2x - 6n^2x + 9mn = 0$

Factorize

$2mx(2nx - 3m) -3n(2nx - 3m) = 0$

$(2mx - 3n)(2nx - 3m) = 0$

Split equation

$2mx - 3n = 0\ or\ 2nx - 3m = 0$

Make x the subject of formula in both expressions

$2mx = 3n\ or\ 2nx = 3m$

$x = \frac{3n}{2m}\ or\ x = \frac{3m}{2n}$

From the list of given options, one of the roots of the equation is $\frac{3m}{2n}$

What is the value of x? 6(x-4)=10

Mrac [35]

Answer:

$\boxed{\sf{x=\dfrac{17}{3}=5.6 }}$

Step-by-step explanation:

Use a distributive property.

Distributive property:

$\Longrightarrow: \sf{A(B+C)=AB+AC}$

⇒ 6(x-4)=10

First, divide by 6 from both sides.

⇒ 6(x-4)/6=10/6

Solve.

⇒ x-4=5/3

Add by 4 from both sides.

⇒ x-4+4=5/3+4

Solve.

5/3+4

4*3/3+5/3

4*3+5/3

4*3=12

12+5=17

x=17/3

Dividing is another option.

17/3=5.6

x=17/3=5.6

Therefore, the final answer is x=17=5.6.

I hope this helps you! Let me know if my answer is wrong or not.
