Answer:
there would be 56 different combinations
Step-by-step explanation:
2 (1/3) + 3 (1/3) is easy to add
2 + 3 = 5
(1/3) + (1/3) = (2/3)
So, it equals 5 (2/3)
She needs 10 - 5 (2/3) more
= 4 (1/3)
<span>You
are paid $78 for 61/2 hours of work.
Question: What is your rate of pay?
=> 78 dollars = is the money paid to you
=> 6 and ½ is the time you rendered for work
=> 6 and half hours = 6.50 hours or 6 hours and 30 minutes
Solution:
=> 78 dollars / 6.5 hours = 12 dollars.
Thus, your rate is 12 dollars per hour (12 dollars/h)</span>
The approximate value of x will be approximately equal to 3.4
<h3>Area of triangle and circle</h3>
The formula for calculating area of rectangle is expressed as:
A = lw
- l is the length
- w is the width
Ar = (3x-1)(x+2)
Ar = 3x^2+6x-x-2
Ar = 3x^2 + 5x - 2
For the circle
Ac = πr²
Ac = 3.14(x-3)²
Ac = 3.14(x²-6x+9)
Ac = 3.14x² - 18.84x + 28.26
If the area are equal;
3x² + 5x - 2 = 3.14x² - 18.84x + 28.26
3.14x² - 3x² - 5x - 18.84x + 30.26 = 0
0.14x²-23.84x+30.26 = 0
On factorizing the equation, the approximate value of x will be approximately equal to 3.4
