Answer:
12.94%
Step-by-step explanation:
r = 100(1/2)^(d/5) = 100((1/2)^(1/5))^d ≈ 100(.87055)^d
The daily decrease is 1 - 0.87055 = 0.12944 ≈ 12.94%
Consider the right angles triangle with hypotenuse 15 and leg 8 cm formed by drawing the diagonal.
The other leg (x) will be the other side of the rectangle and , by Pythagoras we have:-
15^2 = 8^2 + x^2
x^2 = 225 - 64
x^2 = 161
x = 12.69 cms
So the perimeter p = 2*8 + 2* 12.69
= 16 + 25.38
= 41.38 cms (answer)
X is the amount of everything. (total)
x = 20 + j
Answer:
x=61; 125; 55
Step-by-step explanation:
2x+3+x-6=180
3x-3=180
3x=183
x=61
Angle 1=2x+3=2*61+3=125
Angle 2=61-6=55
Find out how much you need for one person then multiply by 18 is one way you could do this..
4 divided by 24 = 0.166666666666667 x 18 = 3 litres of lemon-lime soda.
2 divided by 24 = 0.083333333333333 x 18 = 1.5 pints of servet
6 divided by 24 = 0.25 x 18 = 4.5 cups of ice.
Hope this helps!
Your teacher may have wanted you to (some how) use your 6x tables to work this out?!
