Answer:
552.5
Step-by-step explanation:
2/5x + 68 = 289
2/5 x = 289 - 68
2/5x = 221
x = 221 * 5/2 = 552.5
I hope im right!!!
Answer:
28%
Step-by-step explanation:
3600$ × 20%
=3600 ×(20/100)
=3600 × 0.2
= 720
Actual Price = 3600 - 720
= 2880
Profit is at 4000$ = 4000 - 2880
= 1120$
%profit = (1120/4000) × 100
profit = 28%
The slope of y = -x is m = -1. Thus, starting with the slope-intercept form y = mx + b, we substitute -1 for m, 8 for x and 2 for y, to determine the vaue of b:
2 = -1(8) + b, or 10 = b. Then the equation of the line parallel to y = -x and passing thru (8,2) is:
y = -x + 10.
The first number is 9 and the second number is 10. 10+9=10. 9*2=18 and 10 is 8 less than 18. All the requirements of the numbers are met.
Answer:
10054.4m^3
Step-by-step explanation:
Given data
Height= 32m
Diameter= 20m
Radius= 10m
The expression for the volume of a cylinder is given as
V= πr^2h
Substitute
V= 3.142*10^2*32
V= 3.142*100*32m^3
Hence the volume is 10054.4m^3
