Answer:

45cm^2

Step-by-step explanation:

Area of shaded region = area of outer triangle – area of the unshaded triangle

the area of a triangle is (base × height) ÷ 2

Area of outer triangle:

(12 × 5) ÷ 2 = 30cm^2

the area of the unshaded triangle:

(15 × 10) ÷ 2 = 75cm^2

area of shaded region = 75 - 30 = 45cm^2

vaieri [72.5K]

Answer:

Step-by-step explanation:

After adding 88 red marbles, there are 50 blue marbles out of the 204 marbles total.

$\frac{50+x}{204+x}=\frac{5}{12} \\ \\ 600+12x=1020+5x \\ \\ 420=7x \\ \\ x=60$

This differs on what number you want to talk about. 1 is the hundreds, 8 is the tenths, 7 is the ones.
