Answer:the price for one shirt is $7.5
the price for one pair of pants is $18.5
Step-by-step explanation:
Let x represent the price for one shirt.
Let y represent the price for one pair of pants.
Lisa goes to the mall one day and buys four shirts and three pairs of pants for $85.50. This means that
4x + 3y = 85.5 - - - - - - - - - -1
She returns the next day and buys three shirts and five pairs of pants for $115.00. This means that
3x + 5y = 115 - - - - - - - - - - - 2
Multiplying equation 1 by b3 and equation 2 by 4, it becomes
12x + 9y = 256.5
12x + 20y = 460
Subtracting, it becomes
- 11y = - 203.5
y = - 203.5/ -11 = 18.5
Substituting y = 18.5 into equation 1, it becomes
4x + 3×18.5 = 85.5
4x + 55.5 = 85.5
4x = 85.5 - 55.5 = 30
x = 30/4 = 7.5
So hmm notice the picture below
simply get the area of the segment, and subtract it from the area of the circle, what's left, is the difference
notice your circle, has a radius "r" of 18
Answer:
y(20)=14,322
Step-by-step explanation:
We need to solve the equation:
with initial point
with incerments
By Euler's method, we have:
We start with the initial point
And we continue until we reach the value for y(20)
Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
