Given: Numbers 1 to 708, inclusive

Find:

Total digits printed on the paper = ?

Solution:

1 to 9 = 9 - 1 + 1 = 8 + 1 = 9 * 1 digit = 9
10 to 99 = 99 - 10 + 1 = 89 + 1 = 90 * 2 digits = 180

100 to 708 = 708 - 100 + 1 = 608

608 + 1 = 609 * 3 digits = 1827

total = 9 + 180 + 1827 = 2016

Therefore, the total number of digits that are printed on the paper is 2016 digits.

3(2v-9)=5 solve for v

Sonja [21]

Answer:

v=16/3

Step-by-step explanation:

3(2v-9)=5

Multiply 2v and -9 with 3

6v-27=5

Add 27 to both sides

6v=32

Divide both sides by 6

v=16/3

Naomi starts the engine on her small private airplane. The engine drives a propeller with a radius of 8 feet and its centerline

icang [17]

Answer:

5.13 feet

Step-by-step explanation:

Engine is driving the propeller with a radius of 8 feet and its centerline 13 feet above the ground.

And the speed is 700 revolutions per minute, the height of one propeller tip as a function of time is given by:

$h=13+8 \sin(700t)$

We have been asked to find the value of height, 'h', when t=4 minutes.

Plugging the value of time, 't', in the equation, we already know that we need to use degrees (not radians) we get:

$h=13+8 \sin (700 \times 4)$

$h=13+8 \sin (2800)$

$h=13+8 \times (-0.984)$

$h=13+(-7.872)$

$h=13-7.872$

$h=5.128\approx 5.13$

So the height of one propeller tip at t=4 minutes is 5.13 feet.
