Answer:if its like 8+24+35=67
Step-by-step explanation:
Answer:
W= 875+35h
Step-by-step explanation:
W= the amount of water in the pool
h= # of hours
The pool already had 875 gallons of water, so you need to add 35 times the number of hours to find the total amount of water in the pool after filling it.
Answer:
The more often your interest compounds, the more interest you'll earn on your investment. It's easy to see that money grows more quickly when it's earning compound interest than when it's earning simple interest
Step-by-step explanation:
Answer:
1. n = 1/2
2. m = 5/3 or 1 2/3
3. a = 1/4
4. x = 27/8
5. x = 13/6
Step-by-step explanation:
I'm just going to explain step 5 as that is what you specifically needed help with.
First, simplify the second term of the equation:
-6(2.5x-3)
= -15x + 18
(this was done by multiplying -6*2.5x which is 15x and -6(-3) which is 18)
Now, add this simplified second term back to the first term:
3x + 8 - 15x + 18
(the parentheses are unnecessary now because it is all just addition and subtraction, so the order doesn't matter)
Simplify:
-12x + 26 = 0
= -12x = -26
= x = -26/-12
= x = 13/6
Answer:
4) 7.9%
Step-by-step explanation:
Given:
% of milk chocolate = 70%
% of white chocolate = 30%
Total number of chocolate = 20
Number of milk chocolate:
Number of white chocolate:
From the calculations, we now know there are 14 milk chocolates and 6 white chocolates.
2 white chocolates are picked at random without replacement.
Probability first chocolate picked was white:
Probability second chocolate picked was white:
To find probability that both of them are white chocolates, multiply probability of the first and second.
0.3 * 0.2632 = 0.07896
≈ 0.079
Convert to percentage by multiplying by 100.
0.079 * 100 = 7.9%
The probability that they are both
white chocolate is 7.9%
