In a company, 37% of 1500 employees are females.work out the number of males in the company.

a_sh-v [17]

Formula:

$y = p\% \times x$
$p = 37\% \div 100 = 0.37$
$y = 0.37 \times 1500 = 555$
so there are 555 woman working.
$1500 - 555 = 945$
there are 945 men working

Coordinates (-3, 5), ( -3, 8), and (2, 5). The triangles was dilated by a scale favtor of 3. What is the area of the dilated tri

Otrada [13]

Answer:

The area of the triangle is 7.5 unit²

Step-by-step explanation:

Here we have the coordinates given as

(-3, 5) (-3, 8) and (2, 5)

Let us call the points A = (-3, 5)

B = (-3, 8) and

C = (2, 5)

Therefore the lengths of the sides of the triangle are

AB = a = $\sqrt{(-3-(-3))^2+(5-8)^2} = 3$

AC = b = $\sqrt{(-3-2)^2+(5-5)^2} = 5$

BC = c = $\sqrt{(-3-2)^2+(8-5)^2} = \sqrt{34}$

Therefore the Area can be derived from Heron's formula which is

A = $\sqrt{s\times (s-a)\times (s-b)\times (s-c)}$ where s = semi perimeter or (a + b + c)/2

Therefore, plugging the values, we get

s = (3 + 5 + √34)/2 = 6.9155≈6.92

A = $\sqrt{6.92\times (6.92-3)\times (6.92-5)\times (6.92-\sqrt{34} )}$ = 7.499≈7.5.
