Answer:
3.6
Step-by-step explanation:
The average of 9 scores is x.
average = (sum of scores)/(number of scores)
x = (sum of scores)/9
sum of scores = 9x
The sum of the 9 scores is 9x.
The tenth score is 36 more than x, so it is x + 36.
The sum of the 10 scores is 9x + x + 36 = 10x + 36.
The average of the 10 scores is (10x + 36)/10 = x + 3.6
The difference of averages is
x + 3.6 - x = 3.6
The tablecloth has 42" diameter.
Add 8" at each end of the diameter to get 42" + 8" + 8" = 58".
The tablecloth has 58" diameter.
The radius is half the diameter.
Radius = diameter/2 = 58"/2 = 29".
Answer: The radius of the tablecloth is 29".
Answer:
2n
Step-by-step explanation:
To find the 1st term, put n = 1 into the formula, to find the 4th term, replace the n's by 4's: 4th term = 2 × 4 = 8.
Step-by-step explanation:
x+10=116
x=116-110
=106
x=106
♡Let's solve this Step-By-Step!<span>♡
</span>♡<span>Question:
A=2(L+w)
♡</span>To solve for W we need to flip the equation like so:
<span><span>2l</span>+<span>2w</span></span>=<span>a
</span>
♡Now a<span>dd -2l to both sides:
</span><span><span><span>2l</span>+<span>2w</span></span>+<span>−2l</span></span>=<span>a+<span>−<span>2l
</span></span></span><span>2w</span>=<span>a−<span>2<span>l
</span></span></span>
♡<span>Divide both sides by 2:
</span><span><span>2w/</span>2</span>=<span><span>a−<span>2l/</span></span><span>2
</span></span>♡<span>Your answer shall be:
</span>w=<span><span><span>1/2</span>a</span>−l
</span>
♡Hope this helps!♡
