Answer:
21.62% more
Step-by-step explanation:
20 mins * 3 = 60 mins (1 hour)
10 baskets * 3 = 30 baskets
3$ * 30 baskets = 90$
90$ - 74$ = 16$
74 / 100 - 0.74
90 / 0.74 = 121.62
So she makes 21.62% more with 3$ per basket.
*I think you meant scientific notation.*
23 in scientific notation would be 2.3 x 10^1.
Answer:
4
Step-by-step explanation:
Easy
1/2+1/2=1 or 2/2
2/2+1/2= 3/2
3/2+1/2= 2
1/2*4=2
1/2+1/2+1/2+1/2=2
there are 4 halves in 2
Hope this helps
The error made by zacharias in solving the quadratic equation 0 = -2x² + 5x - 3 using quadratic formula is; the 2 in the numerator should be –2.
<h3>Quadratic equation</h3>
There are four methods of solving quadratic equation. Namely;
- Factorization method
- Completing the square method
- Graphical method
- Formula method
0 = -2x² + 5x - 3
x = -b ± √b² - 4ac / 2a
where,
x = -b ± √b² - 4ac / 2a
x = -5 ± √5² - 4(-2)(-3) / 2(-2)
= -5 ± √25 - (24) / -2
= -5 ± √1 / -2
= -5/2 ± 1/2
= -5/2 - 1/2 or x = -5/2 + 1/2
= -5-1 / 2 or -5+1/ 2
x = -6/2 or -4/2
x = -3 or -2
Therefore, the solution to the quadratic equation is x = -3 or -2
