Altitude- 0n- hypotenuse theorem

(leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse ), that is

x² = (30 - 6) × 30 = 24 × 30 = 720 ( take square root of both sides )

x = $\sqrt{720}$

= $\sqrt{144(5)}$ = $\sqrt{144}$ × $\sqrt{5}$ = 12 $\sqrt{5}$ → b

What is 21⁄4 plus 4 3⁄10? A. 611⁄20 B. 613⁄20 C. 61⁄4 D. 61⁄2

Olegator [25]

Convert 1/4 and 3/10 to have a common denominator:

1/4 = 5/20

3/10 = 620

Now you have 2 5/20 + 4 6/20 = 6 11/20

The answer is A.

Hanadi buys a dishwasher for £240 she wants to put a tag with a price on the dishwashee so that in the sale she can give a disco

Elanso [62]

Answer:

Step-by-step explanation:

Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is

240 + 25/100 × 240 = 240 + 60 = 300

To determine the price tag of 40% discount and that would still ensure that she makes £300,

Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as

x - (40/100 × x) = x - 0.4x = 0.6x

So 0.6x = 300

x = 300/0.6 = 500

So the price tag will be £500
