Answer:

Fraction of work shift represented by 6 hours = 0.6

Step-by-step explanation:

Total work shift of employee = 10 hours

Time considered  to find fraction = 6 hours

Fraction of work shift represented by 6 hours  6/10=3/5=0.6=60%

Fraction of work shift represented by 6 hours = 0.6

Answer:

0.75

Step-by-step explanation:

Total work shift of an employee is 8 hours

Time consist to find fraction is 6 hours

The fraction of work shift by 6 hours :

[tex]\frac{6}{8}[/tex]  =  [tex]\frac{3}{4}[/tex] = 0.75 = 75%

Answer:

first answer

Step-by-step explanation:

Hello, you know that

[tex]\dfrac{\dfrac{a}{b}}{\dfrac{c}{d}}=\dfrac{a}{b}\cdot \dfrac{d}{c}[/tex]

So, the quotient we need to estimate is

[tex]\begin{aligned}\dfrac{x^2-36}{x+8}\cdot\dfrac{4x+32}{x^2+12x+36}&=\dfrac{x^2-6^2}{x+8}\cdot \dfrac{4(x+8)}{(x+6)^2}\\\\&=\dfrac{4(x-6)(x+6)}{(x+6)^2}\\\\&=\dfrac{4(x-6)}{x+6}\end{aligned}[/tex]

Thank you

Answer:

14.48 ft

Step-by-step explanation:

The relation between the location of the focus (c), the vertex on the major axis (a) and the vertex on the minor axis (b) with respect the center is:

b² = a² - c²

From the question:

c = 4 ft

a= 30/2 = 15 ft

Replacing into the equation:

b² = 15² - 4²

b = √209

b = 14.48 ft

So, he should build the whisper chamber at 14.48 ft out from the center along the minor axis

Answer: The answer to this questiojn is 14.48 feet, but if rounded to the nearest tenth, then it should be 14.5 (As it was on my question)

Answer:

I am not totally sure but the answer might be 0.0655.

Do parentheses first:

6 +4-2 = 8

Now do brackets:

128/8 = 16

Now multiply:

16 x 8 = 128

The answer is 128

1. Potential Energy = mgh

h = U_g / (mg) = 14 / (17 * 9.81) = 0.084 m above the ground.

2. Kinetic Energy = 1/2 mv^2

m = 2K_e / (v^2) = 2.45 kg

3. U_g = mgh = (1200)(9.81)(24) = 282528 J

4. U_g = mgh = (478)(9.81)(150) = 703377 J

5. U_g = mgh = (100)(9.81)(12.5) = 12262.5 J

6. h = U_g / (mg) = 14 / (17 * 9.81) = 0.084 m above the ground.

7. m = U_g / (gh) = 1500 /  (9.81 * 35) = 4.37 kg

Answer:

The confidence interval is  [tex]13.4< \mu < 13.8[/tex]

Step-by-step explanation:

From the question we are told that

   The sample  mean is [tex]\= x = 13.6[/tex]

     The standard deviation is [tex]\sigma = 1.9[/tex]

     The sample  size is  [tex]n = 189[/tex]

given that the confidence level is  85% then the level of significance is mathematically represented as

            [tex]\alpha = (100 - 85 )\%[/tex]

            [tex]\alpha = 0.15[/tex]

Next we obtain the critical value  of [tex]\frac{\alpha }{2}[/tex] from the normal distribution table  the value  is  

      [tex]Z_{\frac{\alpha }{2} } = 1.44[/tex]

Generally the margin of error is mathematically represented as

        [tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma}{\sqrt{n} }[/tex]

=>     [tex]E = 1.44* \frac{1.9}{\sqrt{189} }[/tex]

=>     [tex]E = 0.1990[/tex]

The  85%  confidence interval is mathematically represented as  

        [tex]\= x - E < \mu <\= x + E[/tex]

=>      [tex]13.6- 0.1990 < \mu < 13.6+ 0.1990[/tex]

=>      [tex]13.4< \mu < 13.8[/tex]

Answer:

x = 109°

Step-by-step Explanation:

Since AB is parallel to CF, m<BAE = m<AED = 38° (alternate interior angles are congruent)

Since AE = DE, ∆AED is an isosceles ∆.

The two base angles of any given isosceles ∆ are said to be congruent.

This means, m<EAD = m<EDA = ½(180 - m<AED)

m<EDA = [tex] \frac{1}{2}*(180 - 38) [/tex]

m<EDA = [tex] \frac{1}{2}*(142) = 71 [/tex]

x + m<EDA = 180° (angle on a straight line)

[tex] x + 71 = 180 [/tex]

[tex] x + 71 - 71 = 180 - 71 [/tex]

[tex] x = 109 [/tex]

Value of x = 109°

Answer:

36 fliers

Step-by-step explanation:

1/3*72 = 24 fliers posted last week (.333*72)

72-24 = 48 fliers left

1/4*48 = 12 fliers posted this week (.25*48)

48-12= 36 fliers not posted  

Linda has 36 fliers left to post.

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given: Linda had 72 fliers to post around town. Last week, she posted 1/3

of them. This week, she posted 1/4 of the remaining fliers.  

1st-week Linda posted 72/3=24 and remaining fliers72-24=48

2nd the week Linda posted 48/4=12 and remaining fliers 48-12=36

∴The remaining fliers left to be posted are 36

Hence, Linda has 36 fliers left to post.

Answer:

344.1 Ib/ft²

Step-by-step explanation:

This has to do with conversion

23.0Ib/gal × 2ft

Step 1

First we convert 23.0lb/gal to Ib/ft³

1 Ib/gal = 7.48051948 Ib/ft³

23.0lb/gal = X Ib/ft³

Cross Multiply

1 Ib/gal × X Ib/ft³ = 23.0lb/gal × 7.48051948 Ib/ft³

X Ib/ft³ = 23.0lb/gal × 7.48051948 Ib/ft³/1 Ib/gal

X Ib/ft³ = 172.05194804 Ib/ft³ =

Step 2

Since 23.0lb/gal = 172.05194804 Ib/ft³

172.05194804 Ib/ft³ × 2 ft

= 344.10389608Ib/ft²

Approximately to 1 significant figure

Answer:

(11-1-1)(1+1)

Step-by-step explanation:

This question is incomplete, the complete question is;

A rocket is launched straight into the air with initial velocity 200 ft/s. Assume the launch is instantaneous. How high will it go, and how long will that take (use time increments of 0.01 seconds)? G= - 32.2 ft/s² , H₀=0 (the ground)

V(t)=V₀ + g t

H(t)= H₀ + V₀ t + ½ g t²

The rocket deploys a parachute after 9 seconds and descends at a constant rate of 20 ft/sec. How long does it take to reach the ground

Answer:

a) maximum height S is 621.12 ft and time taken to reach it is 6.21 sec.

b) The rocket deploys a parachute after 9 seconds and descends at a constant rate of 20 ft/sec,

Time taken to travel t = 24.79 sec

NOW total time taken = 27.55 sec

Step-by-step explanation:

Given that,

initial velocity u = 200 ft/s

acceleration a = 32.2 ft/s²

vertical displacement ( maximum height) S = ?

final velocity at highest point Ц = 0

NOW from the equation of motion

v² - u² = 2as

we substitute

0² - (200)² = 2 (-32.2) × s

s = 621.12 ft

time taken t = (v -u)/a = (0-200)/-32.2

t = (-200) / (-32.2)

t = 6.21 sec

distance traveled by rocket from t=6.21sec to t=9sec

Δt = (9-6.21) = 2.79sec

s = ut + 1/2at²

s = 0 + 1/2(32.2)(2.79)² = 125.32 ft

Remaining distance = 621.12 ft - 125.32 ft = 495.8 ft

Time taken to travel = t = s/v = (495.5ft) / (20 ft/sec)

t = 24.79 sec

NOW total time taken = 2.79sec + 24.79sec = 27.55 sec

Answer:

Approximately 201 squared inches.

Step-by-step explanation:

So, the composite figure is made up of a square and a semi-circle. The square has side lengths of 12 and the semi-circle has a radius of 6.

The total area of the figure would be the area of the square plus the area of the semi-circle. Thus, find the area of each individual figure.

Square:

The area of a square is given by:

[tex]A=l^2[/tex]

Where l is the side length.

Substitute 12 for l:

[tex]A=(12)^2\\A=144\text{ in}^2[/tex]

So the square is 144 square inches.

Semi-circle:

The area of a semi-circle is given by:

[tex]A=\frac{1}{2}\pi r^2[/tex]

Substitute 6 for r and 3.14 for π:

[tex]A=\frac{1}{2}(3.14)(6)^2\\ A=56.52[/tex]

Therefore, the total area is:

[tex]TA=144+56.52\\TA=200.52\text{ in}^2\approx201\text{ in}^2[/tex]

Answer: About 88 inches

=============================================

Explanation:

Find the circumference

C = pi*diameter

C = (22/7)*28

C = 88

The tire's circumference is approximately 88 inches. This is the perimeter or distance around the circle. As the bike moves forward one full rotation of the wheel, all of the wheel will touch the ground at some point. The bike will move about 88 inches forward when the wheel does one full rotation.

A good way to visualize this is to imagine cutting the tire so that you can unroll it to lay it out completely flat forming a straight line. This line will be roughly 88 inches long.
