Answer:
x = c - a / -b
Step-by-step explanation:
a - bx = c
-a -a
-bx = c - a
divide -b
x = c - a / -b
Answer:
6300 mm
Step-by-step explanation:
A ratio of 11x to 10x
Where x is a number to keep the ratio the same.
Perimeter = 84
Perimeter = 2 (Length + breadth)
84 = 2 ( 11x + 10x)
84 = 2(21x)
21x = 42
x=2
So that means the actual length of the sides would be:
11 x 2 : 10 x 2
22 : 20
So that means the length can be 22, and the breadth will be 20.
Or the length is 20, and the breadth is 22.
Answer:
Yes
12, 35, 37
16, 30, 34
20, 21, 29
No
18, 24, 42
Step-by-step explanation:
Required
Determine which length form a right triangle
To do this, we make use of Pythagoras theorem where the square of the largest length = the sum of the squares of the other lengths
So:
(1) 12, 35, 37 --- Yes



(2) 16, 30, 34 --- Yes



(3) 18, 24, 42 --- No




(4) 20, 21, 29 -- Yes



The formula is
A=p (1+r)^t
A future value?
P present value 4000
R interest rate 0.06
T time 7 years
A=4,000×(1+0.06)^(7)
A=6,014.52
Interest earned=A-p
6,014.52−4,000=2,014.52
Hope it helps!
