Answer:

i dont know what the toatle mass of the barries is im preaty sure you are suppost to tell us that so we can awser but what you need to do is...

Step-by-step explanation:

add everything up, the toatle mean add so for example if it is

berry 1=2.64 mass

berry 2=5.93 mass

and berry 3 is 0.96 mass

you need to add everything up

2.64+5.93+0.96 = ?

9.53 that is the toatle mass for my example

WARNING!! do not put this as your awnser this is an example so this is not the answer!!

HOPE THIS HELPS!!

Answer:x=2.114

Step-by-step explanation:

Given

$10^{x+1}-10^{x-1}=1287$

$10\times 10^x-\frac{10^x}{10}=1287$

Let $10^x=y$

$10y-\frac{y}{10}=1287$

$\frac{100y-y}{10}=1287$

$99y=1287\times 10$

$y=\frac{12870}{99}=130$

$10^x=130$

Taking $\log$ both sides

$x\log (10)=\log (130)$

$x=\frac{\log (130)}{1}$

$x=2.114$

Answer:

1. 30

2. 150

Step-by-step explanation:

$3tan^2(x)-1 =0$

Lets assume tan(x) = u

$3u^2(x)-1 =0$

Now we solve for 'u'

add 1 on both sides

$3u^2(x) =1$ , divide both sides by 3

$u^2 = \frac{1}{3}$

Take square root on both sides

$u = +-\frac{1}{\sqrt{3} }$

We replace tan(x) for 'u'

$tan(x) = +-\frac{1}{\sqrt{3} }$

x = 30 because $tan(30) =+\frac{1}{\sqrt{3} }$ in first quadrant

x = 30 (tan is positive in first quadrant)

$tan(x) =-\frac{1}{\sqrt{3} }$

x = 150 because $tan(150) =-\frac{1}{\sqrt{3} }$ in second quadrant

tan is negative in second quadrant
