Answer:
6/1 square feet per hour. Jeff can paint faster.
Step-by-step explanation:
So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.
Hope this helped!
Answer:
$300
Step-by-step explanation:
In this question, we are simply asked to calculate the simple interest on $3000, at a rate of 20% paid after 6 months.
We can do this as follows. Mathematically, it should be remembered that:
S.I = PRT/100
In this case, we lost out the individual values as follows:
P = $3000, R = 20% and T = 6 months = 0.5years, S.I = ?
We substitute the parameters into the equation:
S.I = (3000 * 20 * 0.5)/100 = $300
ANSWER
x=11
EXPLANATION
We want to solve the equation:

Add -8 to both sides:

Square both sides of the equation to get:


Rewrite in the form ax² +bx+c=0


Factor to get,

This implies that,

Checking for extraneous solutions.
When x=6, the original equation becomes,


2+8= 6 is not true.
x=6 is an extraneous solution.
When x=11, the original equation becomes,



This is true, hence x=11 is the only solution.
Answer:
You have to work backwards here
so if you had 100 dollars left and u spent 50 on a radio
100+50=150
Then You spent a 1/6 of it on stationery
So you mustve had 5/6 money left or 150 dollars
so you multiply that to find that
5/6=150/x
5x=900
x=180
so add 30 dolalrs to 150 and you have 180.
the you spent a third
you repeat the same process
the you have ur ANSWER
