6 0

Answer:

1) = 10 \frac{2}{5}  =  \frac{52}{5}

2) =  \frac{252}{25}  = 10 \frac{2}{25}

Step-by-step explanation:

6 \frac{4}{5}  + 3 \frac{3}{5}  \\ (6 + 3) + ( \frac{4}{5}  +  \frac{3}{5} ) \\ 9 +  \frac{7}{5}  = 9 + 1 \frac{2}{5}  \\ 9 + 1 +  \frac{2}{5}  = 10 +  \frac{2}{5}

\boxed{\green{= 10 \frac{2}{5}  =  \frac{52}{5}}}

2 \frac{4}{5}  \times 9 \frac{2}{5} \\  \frac{14}{5}  \times 9 \times  \frac{2}{5 }

\boxed{\green{ =  \frac{252}{25}  = 10 \frac{2}{25}}}

Someone help me integrate this please >_
NISA [10]
∫( (sinx) / (2 - 3cosx)) dx.

From laws of integration:   ∫ f¹(u) / f(u) du = In(f(u)) + constant.

d/dx (2 - 3cosx) =  0 -3(-sinx) = 3sinx.

1/3d/dx(2 - 3cosx) = (1/3)*3sinx = sinx.

∫ ((sinx) / (2 - 3cosx)) dx.      =  ∫ ((1/3) d/dx (2 - 3cosx) / (2 - 3cosx))dx

= 1/3 ∫ (d/dx (2 - 3cosx) / (2 - 3cosx))dx 

= (1/3)ln(2 - 3cosx) + Constant.

At what time is the cake done
svp [43]
<h2>Explanation:</h2>

Here we know that at 3:17 pm you started to bake the cake. The total revolution the minute hand on the clock makes is:

\frac{5}{8}+\frac{13}{24}=\frac{7}{6} \ revolutions

We know that:

1 \ revolution ----------- 60min \\ \\ 7/6 \ revolutions -----------x

Solving for x:

x=\frac{7}{6}\times 60=70 minutes

So it takes 70 minutes after you put the cake in the oven. But:

70minutes=1h \ 10min

Adding this to the initial time:

3:17pm+1h \ 10min=4:27pm

Finally, the cake is done at 4:27 pm, option C.

Enter the value of b that makes the statement true: 5xb is less than 5 but greater than 0.
AlexFokin [52]
0<5xb<5  divide all terms by 5

0<xb<1  divide all terms by x

0<b<x

If you meant 5b as in 5*b then:

0<5b<5  divide all terms by 5

0<b<1

b is infinitely many values between 0 and 1.
