Answer:

$189

Step-by-step explanation:

Let their total amount of spending money be x

given that $135 they spent is 5/7 of their total spending money,

mathematically:

135 = (5/7) x     (multiply both sides by 7)

135 (7) = 5x

945 = 5x

5x = 945  (divide both sides by 5)

x = 945 / 5

x = 189

3. An exclusive clothing boutique triples the price of the items it purchases
Juli2301 [7.4K]

Answer:

a) MARKUP PERCENT = 200%

b) <u>If the cost price of clothing A  = $10</u>

    then its retail price  = $30

   <u> If the cost price of clothing B   = $25</u>

   then its retail price  = $75

Step-by-step explanation:

Let us assume the original price for the clothing = a

Now,  boutique triples the price of the items it purchases for resale.

So, the resale value of the item of clothing = 3 times (Original price) = 3 a

So, here: The resale Value  = 3 a

a)  MARK UP Percentage = (\frac{\textrm{SP - CP}}{CP})  \times 100

\implies \%  = (\frac{3a-a}{a} ) \times 100 =  200 \%

or, the MARKUP PERCENT = 200%

b) Two expressions that represent retail price

<u>If the cost price of clothing A  = $10</u>

then its retail price  = 200% of 10 +  10  = 20 + 10 = $30

<u>If the cost price of clothing B   = $25</u>

then its retail price  = 200% of 25 +  25  = 50 + 25 = $75

The diameter of a circle has endpoints (–3, –10) and (4, –6). What is the equation of the circle?
fredd [130]

Answer:

The center of the circle is midpoint of the diameter:

The radius is equal the distance between C and Q:

An equation of a circle:

(x - a)² + (y - b)² = r²

(a; b) - a coordinates of a center

r - a radius

r = √65; (-3; 2) ⇒ a = -3 and b = 2

subtitute

(x - (-3))² + (y - 2)² = (√65)²

Answer:

the center: (-3; 2)

the radius: √65

the equation of the circle: (x + 3)² + (y - 2)² = 65
