Count the units on the sides. On the Y axis the rectangle is 4 units and on the X axis the rectangle is 6 units. Area of a rectangle=L*W so, 6*4=24. Perimeter is 4*2 and 6*2=8+12=20. Hope this helps!

A camera shop purchases a camera for $56.98 and sells it for $102.56. What is the percent of markup?

Amiraneli [1.4K]

Answer:

180%

Step-by-step explanation:

Set up an equation:

Variable x = percent of markup

102.56/56.98 = x/100

Cross multiply

102.56 × 100 = 56.98 × x

10,256 = 56.98x

Divide both sides by 56.98:

179.99297.... = x

Round to nearest whole number:

180 = x

Check your work:

56.98 × 180%

Convert the percentage into a decimal:

56.98 × 1.80

102.564

Round to nearest cent:

102.56

What is the solution to the equation below? √2x/√x-1=2 A. 4 B. 2 C. 5 D.3

nikdorinn [45]

Given:

The given equation is:

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

To find:

The solution for the given equation.

Solution:

We have,

$\dfrac{\sqrt{2x}}{\sqrt{x-1}}=2$

On simplification, we get

$\sqrt{2x}=2\sqrt{x-1}$

Squaring both sides, we get

$2x=4(x-1)$

$2x=4x-4$

$2x-4x=-4$

$-2x=-4$

Divide both sides by -2.

$x=\dfrac{-4}{-2}$

$x=2$

Therefore, the correct option is B.
