Answer:

(A) 120 mph

(B) -120 mph

(C) 12 hours 5 minutes.

Step-by-step explanation:

Given that,

New York and California are 2900 miles apart,

Both the trains A as well as B travel at an average speed of 120 mph.

Assuming that the path between the starting point in New York and the ending point in California is straight, so the given distance of 2900 miles is actually the shortest distance which is the displacement between the source and destination.

So, the given speed on the straight path is actually the velocity.

Assuming that the velocity is positive in the direction from New York towards California.

(A) So, the velocity of train A (towards California)  = 120 mph.

(B) The velocity of train B (towards New York) = -120 mph.

(C) Bothy are moving towards each other, so the relative velocity between them is 120+120=240 mph, and the initial distance between them is 2900 miles.

When they meet, the displacement between them becomes zero, displacement covered= 2900-0=2900 miles.

So, the time, t, taken to cover the displacement 2900 miles with a relative velocity of 240 mph is

[tex]t=\frac{2900}{240}[/tex] [as time= displacement / relative velocity]

[tex]\Rightarrow t=12\frac{1}{12}[/tex] hours

=12 hours 5 minutes.

Answer:

12 movies

Step-by-step explanation:

Given

VIP

[tex]Base\ Amount = \$27[/tex]

[tex]Per\ movie = \$6[/tex]

Regular

[tex]Per\ movie = \$8.25[/tex]

Required

Determine the number of movies where they pay the same amount

Represent the number of movies with m.

For VIP, we have..

[tex]Expression = 27 + 6 * m[/tex]

[tex]Expression = 27 + 6m[/tex]

For regular, we have

[tex]Expression = 8.25 * m[/tex]

[tex]Expression = 8.25m[/tex]

Equate both expressions

[tex]8.25m = 27 + 6m[/tex]

Collect Like Terms

[tex]8.25m - 6m = 27[/tex]

[tex]2.25m = 27[/tex]

Solve for m

[tex]m = 27/2.25[/tex]

[tex]m = 12[/tex]

Answer:

E. 12

Step-by-step explanation:

1. p÷q=3. p+q=8 We know that p and q are positive, as dividing by a negative number gives a negative product.

2. 4÷4 does not equal to 3, so neither p nor q can equal 4.

3. As 6÷2=3, p=6 and q=2, or it could be the other way around.

4. Since p=6 and q=2, 6x2=12.

5. pq=12.

Hope the explanation helps you!

Answer:

Step-by-step explanation:

Step-by-step explanation:

Let S be the number of single tickets sold.

Let C be the number of couple tickets sold.

[tex]20s + 35c = 2845[/tex]

[tex]s + c = 128[/tex]

Multiplying the lower system by -20 we get;

[tex]20s + 35c = 2845[/tex]

[tex] - 20s - 20c = - 2560[/tex]

Adding the two systems i get;

[tex]35c - 20c = 2845 - 2560[/tex]

[tex]15c = 285[/tex]

[tex]c = \frac{285}{15} = 19[/tex]

Substituting C=19 in s+c=128,

we get that;

[tex]s + 19 = 128[/tex]

[tex]s = 128 - 19[/tex]

[tex]s = 117[/tex]

Answer:

Percentage of light that penetrates at 150 m will be 0.94%.

Step-by-step explanation:

By using logarithmic regression calculator,

Equation of the regression line will be,

y = 104.5173 - 20.6711(lnx)

Where x represents the depth of the ocean

And y will represent the penetration of light

Therefore, at the depth of 150 m, penetration of the light will be,

y = 104.5173 - 20.6711[ln(150)]

  = 104.5173 - 103.5753

  = 0.9420

  ≈ 0.94 %

Therefore, percentage of light that penetrates at 150 m will be 0.94%.

Answer:

%15.5

Step-by-step explanation:

200+(200x)=231

*x is the interest rate

so let's break down this question by going backwards. we can subract 200 from both sides since we cann easily get rid of +200. so you would get:

200x= 31

Now divide both sides by 200 to eliminate anything else, just to keep x alone.

x= 0.155

and a percent it would be %15.5

and to check:

200+(200*0.155)= 231

Answer:

Step-by-step explanation:

number of members increased by ❌ number of weeks

This is really simple, all you have to do is establish a new relation which describes this particular case;

For example if i wanted to find the area of the full circle (360°), i would use the equation which states that;

[tex]a = \pi \: r {}^{2} [/tex]

[tex]a = \pi \: 8 {}^{2} [/tex]

[tex]a = 3.14 \times 64[/tex]

[tex]a = 201.06 \: inches {}^{2} [/tex]

But do i really wan the full 360 degrees?

In reality i only need a 70 degree circle (in a sense).

If 360 makes a full circle

How many circles is 70?

Use the triple rule to find that;

[tex]x = \frac{70}{360} = 0.1945 \: cirles[/tex]

So that area would be;

[tex] \alpha = 0.1945 \times 201.06 = 39.0617 \: [/tex]

That is your area. a=39 inches² rounded to the nearest tenth.
