He needs to earn ; 77.99-20= 57.99 dollars
so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars
so no of week = 57.99÷ 36= 1.6 weeks
so weeks are in natural no thus it will take him 2 weeks !!
Answer:
<h2>7</h2>
Step-by-step explanation:
Look at the picture.
We have the triangle 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2.
Therefore we have the equation:
Answer: 5:1
Step-by-step explanation:
15 divided by 3 is 5, and 3 divided by 3 is 1
Y^2+5y the greatest common factor is y so
y(y+5)
...
4x^2-49 this is a "difference of perfect squares" which always factors to:
(a^2-b^2)=(a-b)(a+b), in this case:
(2x-7)(2x+7)
...
5s^2-20 GCF is 5
5(s^2-4) now the parenthetic term is a difference of squares so
5(s-2)(s+2)
For acceleration use this formula: (v-u) /t
V is the final velocity
U is the intial velocity and t is time.
For speed u hav to calculate the the total distance and total time then use this formula:
Average speed=
Total distance / Total time
