Answer:
28 Kg : 8 Kg
Step-by-step explanation:
Sum the parts of the ratio, 7 + 2 = 9 parts
Divide 36 Kg by 9 to find the value of one part of the ratio.
36 Kg ÷ 9 = 4 Kg ← value of 1 part of the ratio, thus
7 parts = 7 × 4 Kg = 28 Kg
2 parts = 2 × 4Kg = 8 Kg
36 Kg in the ratio 7 : 2 = 28 Kg : 8 Kg
Answer:
The domain of the function is (-∞,∞), otherwise known as all reals.
Step-by-step explanation:
Answer:
A=9in,b =9in
Step-by-step explanation:
This is a right angled triangle
Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)
So, a2 × b2 = c2
But both sides are equal, so we can as well say 2(a2) = (9|2)^2
2a^2 = 162
Divide through by 2
A^2 = 81
So, a = |81
A = 9
And since both sides are equal, a = b = 9
Multipy 8x11= 88 Then add that to 5x8= 40. Add 88+40 and you get 128. I hope this helps.
