Answer:
3.5m is 500% of 70 cm and 70 cm is 20% of 3.5m.
Step-by-step explanation:
70 cm = 70cm/100= 0.7m
To solve the first problem use this equation:
3.5/0.7 *100 to get 500%
And to solve the second problem you use the same equation:
0.7/3.5*100 to get 20%
Hope this helps you.
The mean is the average of the data. To get the mean you add all the values and then divide by the number of values there were. This gives you a true idea of where the data set is balanced.
Hope that helps.
Answer:
T(x) or total account balance = C(x) + S(x)
Step-by-step explanation:
where = C(x) = -2401 - 140 + 1,400
and
S(x) = 4503 + 100
This implies that:
C(x) = 3,661
S(x) = 4,603
Therefore, T(x) 3,661 + 4,603 = 8,264
T(x) is the total account balance or the addition of the balances of checking and saving accounts.
C(x) is the checking account balance.
S(x) is the saving account balance.
Answer:
- Answer 2) 3a(16a^2-25)
- Answer 4) 3a(4a+5)(4a-5)
- Answer 5) -3a(25-16a^2)
- Answer 6) -3a(5-4a)(5+4a)
Step-by-step explanation:
The factors of each term are ...
So, the greatest common factor is 3a. Factoring that out gives ...
3a(16a^2 -25) . . . . . . matches answer 2
The factor in parentheses is the difference of squares, so it can be factored. You have memorized the form for the difference of squares ...
p^2 -q^2 = (p -q)(p +q)
so you know the factoring of this with p=4a and q=5 will be ...
3a(4a -5)(4a +5) . . . . . . matches answer 4
__
Any <em>pair</em> of factors can be multiplied by -1 without changing the value of the expression. So, two more answers are equivalent:
(-3a)(-(16a^2 -25) = -3a(25 -16a^2) . . . . . . matches answer 5
(-3a)(-(4a -5)(4a +5) = -3a(5 -4a)(5 +4a) . . . . . . matches answer 6
