By the Pythagorean Theorem:
L^2=20^2+15^2
L^2=400+225
L^2=625
L=25 m
5^4/5
Multiply the number by it's exponent
625/5
Divide
Final Answer: 125
Answer:
4
Step-by-step explanation:
-2 + 6 = 4
250/5 = 50.....so each person is stacking 50 chairs...
50/20 = 2.5 minutes....so it takes each person 2.5 minutes to stack 50 chairs.
so ur answer is 2.5 minutes
Answer:
n=-22
Step-by-step explanation:
rewrite the equation as <u>5(n+4)</u><u> </u>= n-8
3
now distribute the 5 through the parentheses <u>5n</u><u>+</u><u>2</u><u>0</u><u> </u>= n-8
3
multiply each side by 3 5n+20=3n - 24
subrtact 3n from both sides 5n+20=3n - 24
-3n -3n
2n+20=-24
then subtract 20 from each side 2n +20=-24
-20 -20
Giving you 2n=-44 then divide both sides by 2
<u>2n</u>=<u>-44</u><u> </u>Giving you n=-22
