3/7 * -2 1/5 = (turn ur mixed number into an improper fraction)
3/7 * - 11/5 = (now just multiply straight across)
(3 * -11) / (7 * 5) = -33/35 <====
First year: the depreciation is (35/100) x 20000 = £7000; now the value of the car is £20000 - £7000 = £13000;
Second year: the depreciation is (35/100) x 13000 = £4550; the current value of the car is £13000 - £4550 = £8450.
The area of a square with sides of length s is
A=s^2, and we are told A=25 so
s^2=25
s=√25
s=5m
Answer:
17m³
Step-by-step explanation:
==>Given:
Prism with right triangular base with the following dimensions:
Height = 17m
Base area = area of the right triangle = ½×2×1 = 1m²
==>Required:
Volume of prism
==>Solution:
Volume of prism = Base area × height of prism
Volume of prism = 1m² × 17m
Volume = 17m³
Answer:
x=4
Step-by-step explanation:
It suffices to equate any two sides and then check whether the solution is valid for the third side.
Taking 2x and 3x-4 and equating:
2x = 3x-4
x = 4
This means the sides are both of length 8. Now check whether for x=4 the third side is also of length 8:
x+4=4+4=8
which indeed works out confirming x=4 being a valid solution
