Answer:

The rate at which the distance between them is changing at 2:00 p.m. is approximately 1.92 km/h

Step-by-step explanation:

At noon the location of Lan = 300 km north of Makenna

Lan's direction = South

Lan's speed = 60 km/h

Makenna's direction and speed = West at 75 km/h

The distance  Lan has traveled at 2:00 PM = 2 h × 60 km/h = 120 km

The distance north between Lan and Makenna at 2:00 p.m = 300 km - 120 km = 180 km

The distance West Makenna has traveled at 2:00 p.m. = 2 h × 75 km/h = 150 km

Let 's' represent the distance between them, let 'y' represent the Lan's position north of Makenna at 2:00 p.m., and let 'x' represent Makenna's position west from Lan at 2:00 p.m.

By Pythagoras' theorem, we have;

s² = x² + y²

The distance between them at 2:00 p.m. s = √(180² + 150²) = 30·√61

ds²/dt = dx²/dt + dy²/dt

2·s·ds/dt = 2·x·dx/dt + 2·y·dy/dt

2×30·√61 × ds/dt = 2×150×75 + 2×180×(-60) = 900

ds/dt = 900/(2×30·√61) ≈ 1.92

The rate at which the distance between them is changing at 2:00 p.m. ds/dt ≈ 1.92 km/h

f + 6 = ?

Well, the answer can be pretty much any number. It all depends on what number f is. f is a variable, so you can plug in any number to replace f.

For example, if f was 5, this is what the equation would look like:

5 + 6 = 11

If f was -3, this is what the equation would look like:

-3 + 6 = 3

So, again, the answer can be anything. It depends on what f is.

Answer:

Step-by-step explanation:

27 + D + 2A + C = 25 + D + B + C + A

subtract D, A, C on both sides

=> 27 + A = 25 + B

=> B = A + 2

3D + A + 29 = 2B + D + A + 27

=> 2D + 29 = 2B + 27

=> 2D = 2B + 27 - 29

=> D = B - 1

substitute:

27 + (B - 1) + 2(A + 2) + A = 2A + B + 30

substitute again:

2A + (A + 2) + 30 = 3A + 32

Answer:

60

Step-by-step explanation:

<C+<D = 180 since they form a straight line

5x+20 +3x = 180

8x+20 = 180

Subtract 20 from each side

8x+20-20 = 180-20

8x = 160

Divide by 8

8x/8 = 160/8

x = 20

We want to find angle D

<D = 3x= 3*20 = 60

Answer:

D

Step-by-step explanation:

Given

- [tex]\frac{1}{2}[/tex] ( - [tex]\frac{3}{2}[/tex] x + 6x + 1) - 3x ← distribute parenthesis

= [tex]\frac{3}{4}[/tex] x - 3x - [tex]\frac{1}{2}[/tex] - 3x

=  [tex]\frac{3}{4}[/tex] x - 6x - [tex]\frac{1}{2}[/tex]

= [tex]\frac{3}{4}[/tex] x - [tex]\frac{24}{4}[/tex] x - [tex]\frac{1}{2}[/tex]

= - [tex]\frac{21}{4}[/tex] x - [tex]\frac{1}{2}[/tex]

= - 5 [tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] → D

Answer:

12 apple pies

Step-by-step explanation:

If he uses 6 apples for each pie and he has 12 bags of apples with 6 apples in each bag, then we can infer that each bag is one pie.

So, 1x12 = 12 apple pies

Answer:

Solution given:

let age of Jailah be x and grandfather's age be y

according to the question

x=¼y-5.....(1)

x=12...........(2)

Now substituting value of x in equation 1

12 =¼y-5

12+5=¼y

17=¼y

doing crisscrossed multiplication

17*4=y

y=68

Jailah’s grandfather is 68 years old.

Answer:

Step-by-step explanation:

Answer:

y = 3/2x - 5

Step-by-step explanation:

y = 3/2x + b

1 = 3/2(4) + b

1 = 6 + b

-5 = b

Answer:

i. Two angles can be vertical and supplementary.

ii. Yes, we can determine the angles.

Step-by-step explanation:

When two angles are vertical, it implies that they are equal (with respect to vertical opposite property). While two angles are supplementary if and only if they add up to 180 degrees .

It is not mandatory for the two angles to be beside each other so as to be supplementary. So that in this special case, the only measure of angles that can be both vertical and supplementary is 90 degrees .

This answer is right. Please mark Brainliest!

Step-by-step explanation:

Answer:

[tex]1.8[/tex]

Step-by-step explanation:

Since the time for the pot of water to boil is inversely proportional to the cooker setting, H, as one goes up, the other must go down:

[tex]T\propto \frac{1}{H}[/tex]

Convert 5 minutes to seconds:

[tex]5\cdot 60=300\:\mathrm{s}[/tex]

Therefore, from the initial data given (When H=6, T=90), the new time is [tex]\frac{300}{90}=3\frac{1}{3}[/tex] larger. Therefore, H must be [tex]3\frac{1}{3}[/tex] times smaller for them to be inversely proportional.

[tex]H=\frac{6}{3\frac{1}{3}}=\boxed{1.8}[/tex]

Answer:

Pretty sure 4.1 is an even number, 88° to be exact.

since your homework is quite much and kinda boring, the only thing you could offer me as motivation are brainliests. like in reposting the same sheet.

but this here for free: the of all three angles inside a triangle is 180 degrees.

half a turn of a full circle is 180 degrees, wich is important to calculate excercises 2 and 3 using subtraction.

for the first brainliest you can have 1-4

for the second 5-7 and for the third and fourth 8-9 and 10-11.

the whole sheet for a maybe-brainliest just isn't enough. it's like half an hour of grind work man

Answer:

Step-by-step explanation:

(2x-5)(x+6)=0

either 2x-5=0               Or, x+6=0

2x-5=0

2x=0+5

x=5/2

x+6=0

x=0-6

x=-6

so x=5/2 , x=-6

f(x)=3x−4 Input is x=3 , Output is

3X3-4= 5

f(x)=−4x+3 Input is x=−3 , Output is

4x-3 +3 = -9

f(x)=−x−1 Input is x=−4 , Output is

-(-4-1) =-(-5) =5

f(x)=x2 Input is x=5 , Output is

5x2=10

hope it will help you
