A train left at 22:47 and arrived at its destination the next morning at 6:33. How long did the journey take

Answer:

[tex]4.2\ \text{cm}[/tex]

Step-by-step explanation:

d = Diameter of wheel

The difference between the circumference and diameter of a wheel is 18 cm.

[tex]2\pi r-d=18\\\Rightarrow \pi d-d=18\\\Rightarrow d(\pi-1)=18\\\Rightarrow d=\dfrac{18}{\pi -1}\\\Rightarrow d=\dfrac{18}{3.14-1}\\\Rightarrow d=8.41\ \text{cm}[/tex]

The diameter of the wheel is 8.41 cm so the radius will be [tex]\dfrac{8.41}{2}=4.205\approx 4.2\ \text{cm}[/tex].

Answer:

it would be 5

Step-by-step explanation:

any of the answer could have really worked (not 4 since that gives you less then what is needed) but in the end it would have been 5 because 5 leaves you with only 5.33 feet of rope left

80* any one of the four numbers (ex: 5) = your answer that you got (ex: 400)

then you divide that number by 28 (ex: 33.33) and if you want to go the extra mile then do the number that you got by dividing 28 minis the number of rope pieces needed

the whole thing >

80* 5 = 400

400/28 = 33.33

33.33- 28 = 5.33

Answer:

[tex]21\ \text{square units}[/tex]

Step-by-step explanation:

The points are [tex]D(-3,5), E(-3,-2)[/tex] and [tex]F(3,0)[/tex].

Area of a triangle is given by

[tex]A=\dfrac{D_x(E_y-F_y)+E_x(F_y-D_y)+F_x(D_y-E_y)}{2}[/tex]

[tex]\Rightarrow A=\dfrac{-3(-2-0)+-3(0-5)+3(5-(-2))}{2}[/tex]

[tex]\Rightarrow A=21\ \text{square units}[/tex]

The area of the given triangle is [tex]21\ \text{square units}[/tex].

Answer:

1) x = 71

2) x = 117

5)

m<1: 35

m<2: 77

m<3: 52

m<4: 77

m<5: 65

m<6: 25

Step-by-step explanation:

1)

x + 41 + 68 = 180

x + 109 = 180

x = 71

2)

x + 47 + 16 = 180

x + 63 = 180

x = 117

3)

<2 + 103 = 180

<2 = 77

<1 + 68 + 77 = 180

<1 + 145 = 180

<1 = 35

<4 + 103 = 180

<4 = 77

<5 + 41 + 77 = 180

<5 + 115 = 180

<5 = 65

<6 + 65 = 90

<6 = 25

<3 + 103 + 25 = 180

<3 + 128 = 180

<3 = 52

Step-by-step explanation:

Answer:

P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998 Step-by-step explanation:

P(t)=80(0.98)t P ( t ) = 80 ( 0.98 ) t , where t is the number of years since 1998

The percent decrease of wolves per year is 2%.

To understand more, check below explanation.

A population of wolves in a county is represented by the equation,

                        [tex]P(t)=80(0.98)^{t}[/tex]

where t is the number of years.

Let us consider that, 1998 is base year. so that, t = 0

                 [tex]P(0)=80[/tex]

Population of wolves in 1999, substitute t=1

             [tex]P(1)=80*0.98=78.4[/tex]

the percent decrease of wolves per year is computed as;

                                      [tex]=\frac{80-78.4}{80} *100\\\\=\frac{1.6}{100}*100\\ \\=0.02*100=2\%[/tex]

The percent decrease of wolves per year is 2%.

Answer:

12 cubic inches

Step-by-step explanation:

volume of a cylinder= pi*r2*height

but we are given 36 as cylinder volume.

Therefore , 36 = pi*r2* height

r2*height = 36/pi, let call this equation 1

volume of a cone = pi*r2*height/3;

but from equation 1, r2*height =36/pi, substituting this value in volume of cone.

volume of cone= pi*(36/pi)/3 = 12 cubic inches

Required

Find [tex]arc\ MN[/tex]

The sum of angles in a semi-circle is 180 degrees.

So:

[tex]arc\ MN + \angle NOP = 180[/tex]

This gives:

[tex]arc\ MN + 150 = 180[/tex]

Hence, the equation is: [tex]arc\ MN + 150 = 180[/tex]

Answer:

0.36x ² + 815.04x + 11,340

Step-by-step explanation:

Revenue = price × quantity

p(x) = x+14

d(x) = 0.36x + 810

Revenue = price × quantity

= (x + 14) * (0.36x + 810)

= 0.36x² + 810x + 5.04x + 11,340

= 0.36x ² + 815.04x + 11,340

Company's revenue = 0.36x ² + 815.04x + 11,340

Answer:

4 8.95h + 10 < 115

Step-by-step explanation:

Answer: 4) 8.95h + 10 < 115

Step-by-step explanation:

We know the inequality will be equal to less than 115 since it states that the order was less than $115.

The equation would look like: some amount of shin guards times 8.95 each + $10 shipping = less than $115

8.95h + 10 < 115

(h in the given equation is the amount of shin guards)

Answer:

$3

Step-by-step explanation:

Since he’s leaving a 20% tip, we need 20% of 15.

To solve, multiply 20/100 (20%) by 15:

20/100*15 = 300/100 = 3

He will leave a $3 tip.

Answer:

$3

Step-by-step explanation:

To solve this problem, first, one must convert the percent of the tip to decimal form. This can be done by dividing the percent by 100. Then one will multiply this value by the total bill.

20% * 15

= 0.2 * 15
