Brandy set her watch 4 seconds behind and it falls behind another 1 second every day. How many days had it been since brandy las

kari74 [83]

Answer:

18 days

Step-by-step explanation:

Let x represent number of days.

We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall $1x$ seconds behind in x days.

We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total $x+4$ seconds in x days.

Since Brady's watch is 22 seconds behind, so we will equate $x+4$ by 22 to solve for x as:

$x+4=22$

$x+4-4=22-4$

$x=18$

Therefore, Brandy set her watch 18 days ago.

Answer:

Step-by-step explanation:

a-b=2

$\frac{27^{\frac{1}{3} b} }{9^{\frac{1}{2}a } } \\=\frac{(3^{3}) ^{\frac{1}{3} b} }{(3^{2} )^{\frac{1}{2} a} } \\=\frac{3^b}{3^a} \\=3^{b-a} \\=3^{-(-b+a)} \\=3^{-2}\\=\frac{1}{3^2} \\=\frac{1}{9}$

Answer:

6.7

Step-by-step explanation:

This is trigonometry. We will have to find the opposite leg and the hypotenuse is given to us as 10. So we will have to use sin.

Soh in Soh cah toa

So sin(42)=x/10

10 times sin(42)=x

Evaluate using a calculator=6.69130606 and so on

Rounded to the nearest tenth is 6.7

So the answer is 6.7
