Answer:

10 cm

Step-by-step explanation:

The area of a triangle

A = 1/2 bh

We know the area and the base

45 = 1/2 * 9*h

45 = 9/2h

Multiply each side by 2/9 to isolate h

45*2/9 = 2/9*9/2h

10 = h

Make X the subject :))
Rom4ik [11]

Answer:

x = \frac{3 + 8y}{y - 1}

Step-by-step explanation:

y = \frac{x + 3 }{x - 8}

Cross multiply,

y(x - 8) = x +3

yx - 8y = x + 3

yx - 8y -x = 3

yx - x     = 3 + 8y

  (y - 1)x = 3 +8y

           x = \frac{3 + 8y}{y - 1}

Sara paid $11.88 total for apples, after a 3 dollar coupon, and $7.58 for berries with a $20 bill. How much change did Sara rece
Nataliya [291]

After the discount, Sara received a change of <u>$3.54</u>.

Define discount.

The discount is <u>determined by dividing the purchase price by the item's par value</u>. Discount is the type of original price reduction or a new lower price for a product. In other words, a discount i<u>s a sum of money or a portion of the regular selling price of anything</u>.

Given that a discount is the price reduction of goods or services that store owners give at the advertised price, it can be computed using the formula <u>Discount = List Price - Selling Price.</u>

Solution Explained:

Given,
Price of apples = $11.88, price of berries = $7.58

The discount on the coupon is $3 and she paid with a $20 bill

So, total cost = 11.88 + 7.58 = 19.46

Applying discount on the cost =  19.46 - 3 = 16.46

The total change Sara gets is = 20 - 16.46 = $3.54

Therefore, Sara receives a change of $3.54
