Answer:
60cm^2
Step-by-step explanation:
use Pythagoras' theorem to find the height (attached)
24/2 = 12
h=5cm
are of a triangle = base x height /2
24 x 5 / 2 = 120/2 = 60
Answer:
y = x + 5
Step-by-step explanation:
The line passes through points (-7,-2) and (2,7)
Slope of the line = change in y ÷ change in x = = 1
Taking another point (x,y) on the line;
Slope = = 1
Cross multiplying this gives;
y - 7 = x - 2
y = x + 5
Mass of 1p=1.67*10^-24
mass of 1,000p=1.67*10^-24*10^3=1.67*10^-21
if that makes sense
Answer:
45 ft^2.
Step-by-step explanation:
Area = area of the square + 2 * area of one triangle
= 5^2 + 2 * 1/2 * 5 * 4
= 25 + 20
= 45 fT^2.
Answer:
25π - 24 cm²
Step-by-step explanation:
area of circle:
A = πr²
A = π(5²)
A = 25π
Area of triangle:
base = 6
height = 5 - 1 = 4
(1/2)(6 * 4) = 12
there are 2 triangles so unshaded area is 24 cm²
Area of shaded region = 25π - 24 cm²
