Answer:
Step-by-step explanation:
We have:
$log_{10} (10)=1$
$\therefore \log_{10}(2\times 5)=1$
$\implies \log_{10}(2)+ \log_{10}(5)=1$
$\implies \log_{10}(5)=1-\log_{10}(2)$
$\implies \log_{10}(5)=1-0.3010=\boxed{0.6990}$

Answer: Choice A) x = 15; y = 17
---------------------
Explanation:
The "7x+7" angle and the "112 degree" angle are congruent. They are vertical angles. So
7x+7 = 112
7x+7-7 = 112-7
7x = 105
7x/7 = 105/7
x = 15
We technically have enough to stop here, but let's keep going to find y
The "4y" angle and the "112 degree" angle are supplementary. They form a single straight line. They add to 180 degrees
So,
4y+112 = 180
4y+112-112 = 180-112
4y = 68
4y/4 = 68/4
y = 17

i don't exactly know
if its right but i did use a calculator
Step-by-step explanation:
spring water is 2.08/16= 13 cents per ounce
fresh water is 2.40/20= 12.5 cents per ounce
fresh water is .5 cents per ounce less expensive
