⇒ s = a+b+c2=5+12+132 a + b + c 2 = 5 + 12 + 13 2 = 15 cm.
Area of the base = √s(s−a)(s−b)(s−c)
= √15×10×3×2 15 × 10 × 3 × 2 cm2 = 30 cm2
Answer:the length of the shorter string= 36cm
Step-by-step explanation:
Let us assume the lengths are 2x and 7x since thery are in the ratio of 2 :7
Such that Length of the shorter string = 2x
and the longer string = 7x so that the difference in Length which is 90cm can be expressed as
7x- 2x= 90
5x= 90
x 90/5
x= 18
shorter string = 2 x = 2x 18= 36cm
Longer strring = 7x 18=126cm
Answer:
Step-by-step explanation:
Hello, please consider the following.
Thank you.
Answer:
its 13 if i saw the numbers right
Step-by-step explanation:
evaluate then you get the below
1-(-4)x(-3)+12/(-6)
___________
-1
divide and get;
-(1-(4)x(-3)+12/(6))
remove parentheses and divide
-(1+4x(-3)-2)
multiply and get
-(1-12-2)
calculate
-(-13)
remove "()"
and you get 13
Y = kx
y = 2k
it is determine how much the increase of y
