Answer:
12.5%
Step-by-step explanation:
Total time = 70 + 4 + 6 = 80 mins
% value- added time
= (4+6)/80 × 100
= 12.5%
where t is the number of hours worked by Natalle
Here, we want to write an equation that will represent the given scenario
Let the number of hours for which she earned the pay be t
From the question, she earns $11 per hour
So for t hours, the amount earned excluding the tip will be;
Now, let us add the tip and equate to the total amount earned
We have this as;
Answer:
H = 2 S = 50 A = 50.2
Step-by-step explanation:
A=2πrh+2πr2
S = 2tr2 + 2trh
S = 2 (t x r) + (h x 2t) x r Try out ^2 for Radius
S = 2t x r^2 + r x h x 2t Rearrange back and cross out for square^2
S = 6t x 4 + 6t x r x h Cross out for t
S = 6 x 4 + 6 x 2 x h Balance out...
S= 24 + 12 x 2 Find h = 2
S = 36 + 24
S= 50 sq2
A = 50. 2
R = 2
H = 2

Area = 6.28318530718 x 4 + 6.28318530718 x 2 x 2 = 50.27sq2

Answer:
72
Step-by-step explanation:
The two digit number can be represented by xy, where x and y must add to 9 and x - y must subtract to 5. Make a system of equations.
Use the elimination method and add the terms from top to bottom like so. The y and -y cancel out.
2x = 14
Divide both sides by 2.
x = 7
Substitute 7 for x into the first equation (either eqn would work).
(7) + y = 9
Subtract 7 from both sides.
y = 2
Combine these two together; xy --> (7)(2) --> 72.
The number is 72.
