Markup=10.82(72/100)≈$7.79  (to nearest cent)

retail=10.82(100+72)/100≈$18.61 (to nearest cent)

If the markup rate for 2 earmuffs is 72%, to calculate the markup, we have to find 72% of the original price, $10.82. "Of" is a word that indicates we must multiply the percent by the price--to do that, we must convert the percent into a decimal, like so:
72percent =  \frac{72}{100} =  0.72
Next, multiply the decimal form of 72% by the original cost:
0.72 * 10.82 = 7.79
The markup is $7.79.

To calculate the new price, we have to add the original cost and the markup, like so:
10.82 + 7.79 = 18.61
The new retail price is $18.61.

Hope this helps!

anastassius [24]
Solutions

To solve this problem we have to use the Pythagorean theorem. You can only use the Pythagorean theorem in Right Triangles. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

One leg of a right triangular piece of land has a length of 24 yards. They hypotenuse has a length of 74 yards. The other leg has a length of 10x yards.

First leg (24 yards) would be α 

Second leg would be β

Hypotenuse (74 yards) would be c

Now we have points α β c.  

a² (24) + β² ( x ) = c² (74) 

Calculations 

c² = α² + β²

74² = 24²+ β² 

<span>5476 = 576 + </span>β² 

5476 - 576 = β²
<span> </span>
<span>4900 = </span>β² 

→√4900 
<span> </span>
β<span> = 70 yards 
</span>
<span>70 = 10x 
</span>
<span>x = 70</span>÷<span>10 = 7 yards  
</span>
The second leg = 7 yards

pav-90 [236]

Answer:

x=10, y=-5

Step-by-step explanation:

2x+3y=5, y= 5-x; change y to 5-x:

2x+3(5-x)=5

2x-3x+15=5

-x=5-15

-x=-10

x=10

=>y=5-x=5-10=-5

I need help quick thanks!!!
aliya0001 [1]

Answer:

x = 1.5

Step-by-step explanation:

-1.2 (3 - x) = -1.8

<em>Apply distributive property</em>

-3.6 + 1.2x = -1.8

<em>Get 1.2x alone so add -3.6 to each side</em>

1.2x = 1.8

<em>Get x alone so divide 1.2 on each side</em>

x = 1.5

Hope this helps!
