The area of a rectangular painting is 5/8 square yard. The width is 3/4 yard. What is the length of the painting?

vfiekz [6]

Answer:

The answer is

<h2> $\frac{5}{6} \: \: \: \: yards \\$ </h2>

Step-by-step explanation:

Area of a rectangle = length × width

Since we are finding the length of the rectangle

$length = \frac{area}{width} \\$

From the question

area = 5/8 square yards

width = 3/4 yard

So we have

$length = \frac{5}{8} \div \frac{3}{4} \\ = \frac{5}{8} \times \frac{4}{3} \\ = \frac{5}{2} \times \frac{1}{3}$

We have the final answer as

$\frac{5}{6} \: \: \: \: yards \\$

Hope this helps you

Jessica was given the area and the length of the base of a triangle. A = 17.5 units, b = 5 units. She solved the formula for are

pychu [463]

Answer:

She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid

Step-by-step explanation:

A=1/2 x b xh

17.5 = 1/2 x 5 x h

35=5h (multiply both sides by 2 to get rid of one half)

35/5 = 5h/5

7=h

The height of the triangle is 7 units

Please mark me brainliest, it really helps!

Rewrite in standard form of a circle<br> x^2-6x+y^2-4y-12=0

cricket20 [7]

Answer: $(x-3)^{2}$ + $(y-2)^{2}$ = $5^{2}$

Step-by-step explanation:

The standard form of equation of a circle is written in the form:

$(x-a)^{2}$ + $(y-b)^{2}$ = $r^{2}$

where a and b are the coordinates of the center and r is the radius.

All we need to do is to covert the given equation into this form, how do we do that?

We will achieve this by using the completing method of solving quadratic equation.

Firstly re - write the equation , that is

$x^{2}$ - 6x + $y^{2}$ -4y = 12

The next thing is to Complete the square for each of x and y

How do we do this ?

i. multiply the coefficient of x and y by 1/2

ii. square the results

iii. Add the result to both sides of the equation , that is

$x^{2}$ - 6x + $3^{2}$ - 4y + $2^{2}$ = 12 + $3^{2}$ + $2^{2}$

The next thing is to write the Left hand side of the equation as a perfect square binomial and simplify the Right hand side. That is

$(x-3)^{2}$ + $(y-2)^{2}$ = 25 , that is

$(x-3)^{2}$ + $(y-2)^{2}$ = $5^{2}$

Which is now in standard form of the equation of a circle.
