Answer:
P=106
Step-by-step explanation:
A=a2
P=4a
Solving forP
P=4A=4·702.25=106
So firstly let’s set a ‘algebra’
Let’s make the hours working after school as ‘x’
So Chase works totally 18 hours last week
So the hours he works on Saturday is (18-x)
And given the salary of working after school is $8 per hour,and the salary of working on Saturday is $10,and he earned $156
So with these we can write a equation
8x+10(18-x)=156
solve it,
8x+180-10x=156
-2x=-24
X=12
as I said x is the hour working after school
The hour working on Saturday should be 18-x
18-12=6
Answer is 6
It is centered at (h,k) --> (0,0) and has a radius 9
The equation of the circle is
Hope that helps!
3/5 is equivalent to 0.6
This is because if you times 2 to the numerator and denominator(top and bottom of the fraction) you will get 6/10 which is 0.6
Answer:
8 m/s^2
Step-by-step explanation:
F=kA
F=force
k=constant you will use for each F=kA relation
A=acceleration
Second sentence says F=90 while A=10 (plug in and find k)
90=k(10) so k=9
We have for any (A,F) that F=9A
Last sentence F=72, what is A?
So 72=9A which means A=8 m/s^2
