Answer:

The tail of a 1-mile long train exits a tunnel exactly 3 minutes after the front of the train entered the tunnel. If the train is moving 60 miles per hour, how long is the tunnel? Hint : How far does the front of the train move in 3 minutes?

Explanation

The front of the train moves 3 miles in 3 minutes. Therefore, the tunnel must be 1 mile long.

Answer:

2 miles long

Step-by-step :

The tail of the train starts one mile from the mouth of the tunnel and it must travel that distance plus the length of the tunnel in 3 minutes.

Let t = tunnel length

t + 1  = distance the tail must travel in 3 minutes.

3 minutes = 1/20 hr

(t+1) miles  /  60 m/hr  = 1/20 hr

t + 1 = 60/20

t+1 = 3

Subtract 1 from each side:

t = 2

The tunnel is 2 miles long.

Answer:

The answer is 81.85%

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean.

The z score is given by:

z = x - μ/σ

where,

For x = 88

z = 88 - 116/14

z = (-2)

For x = 130

z = 130 - 116/14

z = (1)

Thus,

P(88 < x < 130) = P(-2 < z < 1)

= P(z < 1) - P(z < -2)

= 0.8413 - 0.0228 = 81.85%

Thus, 81.85% of the population would be between 88 and 130.

The line has negative slope and y-axis intercept = 2  from inspection

 two points on the line are needed to calculate the slope

    find two easy to work-with points

          like   (-3,4)  and  (4,-1)

           slope = (y1-y2) / ( x1-x2)  = (4 - -1) / ( -3-4) =  -5/7

What is a quadrilateral?

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined.

Given that ABCD is a quadrilateral.

The diagonal AC divides the quadrilateral into 2 triangles △ABC and △ACD.

The length of sides AC and CB of the △ABC is same. Thus △ABC is isosceles triangle. Therefore ∠BAC = ∠ABC = x°.

Similarly, the length of sides AC and CD of the △ADC is same. Thus △ADC is isosceles triangle. Therefore ∠CAD = ∠CDA = 66°

Given that ∠DCB = 90°.

∠A = ∠CAD + ∠BAC = 66° + x°

The sum of all interior angle of a quadrilateral is 360°.

Therefore,

∠A + ∠B + ∠C + ∠D = 360°

66° + x° + x° + 90° + 66° = 360°

Add to the like terms:

222 + 2x = 360

Subtract 222 from both sides:

2x = 138

The equation of the parabola would be [tex]y = \frac{1}{4}(x + 1)^2 - 4[/tex].

What is a parabola?

A parabola is a curve that is shaped like a U or a mirror image of a U. It is a type of conic section, which is a curve that is formed by the intersection of a plane and a cone.

The equation of a parabola can be written in the form y = a(x - h)^2 + k, where (h, k) is the vertex of the parabola and a is a coefficient that determines the shape of the curve.

To find the equation of the parabola described in the problem, we can first find the values of h and k and then substitute them into the equation.

We know that the vertex of the parabola is (-1, -4). Therefore, h = -1 and k = -4.

Substituting these values into the equation y = a(x - h)^2 + k, we get:

y = a(x - (-1))^2 + (-4)

= a(x + 1)^2 - 4

Now we can use the fact that the parabola passes through the points (-5, 0) and (3, 0) to find the value of a.

Substituting x = -5 into the equation, we get:

y = a((-5) + 1)^2 - 4

= a(4)^2 - 4

= 16a - 4

Since the point (-5, 0) lies on the parabola, y must equal 0 when x = -5. Therefore, we have the equation 16a - 4 = 0. Solving for a, we find that a = 1/4.

Substituting this value back into the equation for y, we get:

[tex]y = \frac{1}{4}(x + 1)^2 - 4[/tex]

Hence, the equation of the parabola would be [tex]y = \frac{1}{4}(x + 1)^2 - 4[/tex].

The ratio of the mass of Earth to the mass of Jupiter is equal to 3.14*10⁻³, thus option B is correct.

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

Given, the mass of Earth = 5.97*10²⁴ kg

Also, mass of Jupiter = 1.90*10²⁷ kg

Hence, ratio of mass of Earth to Jupiter is calculated by dividing mass of Earth upon the mass of Jupiter.

Ratio = (5.97*10²⁴/1.90*10²⁷ )

= 3.14*10²⁴⁻²⁷

= 3.14*10⁻³

Thus, the ratio of the mass of Earth to the mass of Jupiter is equal to 3.14*10⁻³, thus option B is correct.

A repeating decimal is a decimal number with a digit (or group of digits) that repeats forever.

There are three ways to show a repeating decimal:

[tex]\sf 0.19\overline{2}[/tex]

This is a repeating decimal as the line over the "2" means that this digit repeats forever.

[tex]\sf 0.\overline{314}[/tex]

This is a repeating decimal as the line over the "314" means the group of digits 314 repeats forever, e.g. 0.314314314...

This is a repeating decimal as there are two duplicates of the repeating block of digits "53" followed by an ellipsis.

0.7777

This is non-repeating decimal as there are no dots or lines above any of the digits, nor an ellipsis after the repeating digits.

If another freight train leaves an hour later from the same station and also heads east at 25 mph. The second freight train catches up with the first one by 11:12 pm.

Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.

The relative speed for the given condition is,

=25 mph - 20mph

=5 mph

Relative distance = relative speed × time

Relative distance = 5 mph × 1 hour

Relative distance = 5 miles

The time will the second freight train catch up with the first one is obtained as,

Distance = speed × time

5 miles = 25 mph × t

t = 5 / 25

t=0.2 hour

1 hour = 60 minute

0.2 hour = 60 × 0.2

0.2 hour = 12 minute
