Answer:

DAB = 53

Step-by-step explanation:

ABC is congruent to ABD

Therefore

CAB = DAB

ABC = ABD

And

BCA =BDA

We are looking for angle DAB

We know CAB is 53, and that CAB = DAB

DAB = 53

The temperature inside a certain industrial machine at time t seconds after startup, for 0 < t < 10, is given by h(t) = 42

frutty [35]

Answer:

$t= \frac{125}{38} s$

Step-by-step explanation:

We are given the temperature inside the machine from startup until 10 seconds later, the formula is:

$h(t)= 42 \cdot t +1 - 4\cdot t +2 (degrees \, C)$

We want to know at what time t the temperature inside the machine will be equal to 128 °C.

So we set:

$h(t)=128$

$42\cdot t+1-4\cdot t+2=128$

Now, we rearrange the equation to keep terms with t on the left hand side and terms without t on the right hand side

$42\cdot t-4\cdot t=128-1-2$

and we simplify:

$(42-4)\cdot t= 128-2-1= 125$

$38 \cdot t = 125$

now it's easy to solve for t:

$t=\frac{125}{38}$

And thus we arrive to the solution.

Answer:

$\frac{times}{days}$ = $\frac{20}{5}$ = $\frac{m}{30}$

you need to be consistant when setting up the proportions. The times always need to be on top and the days needs to always on bottom.

Cross multiply and solve for the variable.

20(30) = 5(m)

600 = 5m

120 = m

So, in 30 days the theatre showed 120 movies.
