Answer:

3.6 hours

Step-by-step explanation:

The computation of the number of hours will the battery last is given below:

Given that

The capacity of her battery is 2 by 5

And, it declines 1 by 9 for every hour

So,

= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}

= 3.6 hours

(-9,7), (6,2) write an equation in point-slope form of the line that passes through the given points, then write the equation in
skelet666 [1.2K]

Answer:

y = (2 - 7) / (6 - (-9)) * (x - (-9)) + 7

y = -5 / (6 + 9) * (x + 9) + 7

y = -5 / 15 * (x + 9) + 7

y = -1/3 * (x + 9) + 7

y = -1/3 * x - 3 + 7

y = -1/3 * x + 4

What is 25.0996 rounded to the nearest thousandth
madreJ [45]

Answer:

25.100

Step-by-step explanation:

The thousandth place is the third digit to the right of the decimal point - tenths is the first, hundredths is the second, thousandths is the third.  Since six rounds up and both nines round up, one must round up all of the way from the fourth decimal place to the tenth decimal place.

In Circle M, points A, B, and C are located on the circle such that measure angle CBM equals to 34 degrees. What represents angl
Bess [88]

Answer:

Angle CAB=56 degrees

Step-by-step explanation:

See the attached image for the diagram.

In triangle BMC

|BM|=|MC| (Radii of a Circle)

Therefore, triangle BMC is an Isosceles Triangle; and

\angle CBM=\angle BCM=34^\circ

\angle CBM+\angle BCM+\angle BMC=180^\circ$ (sum of \angle s$ in a triangle)\\34^\circ+34^\circ+\angle BMC=180^\circ\\\angle BMC=180^\circ-68^\circ=112^\circ

Next,

\angle BMC=2\angle CAB $(Angle at center is twice angle at circumference)\\112^\circ=2\angle CAB\\\angle CAB=112^\circ \div 2\\\angle CAB=56^\circ
