160 miles.

10:40-11:40 is 60 min., which is 60 miles

11:40-12:40 is 60 min., which is also 60 miles

12:40-1:00 is 20 min. = 20 miles

1:00-1:20 is 20 min. = 20 miles

60+60+20+20 = 160 miles

Answer:

The answer is 160.2 miles.

Step-by-step explanation:

In order to determine the distance, we have to know the total time that train traveled. We know that the train leaves at 10:40 a.m. and arrives at 1:20 p.m.

So,

10:40 a.m. to 11:00 a.m.=20 minutes

11:00 a.m. to 1:00 p.m.=120 minutes

1:00 p.m. to 1:20 p.m.=20 minutes

Then, the total time is 20+120+20=160 minutes. Also we have to know that the speed is the rate of distance per time. The units are miles per hours, thus 160 min=2.67 hours.

S=speed of the train.

D=distance of the train.

T=total time of the train.

[tex]S=\frac{D}{T}\\60=\frac{D}{2.67}\\D=60*2.67\\D=160.2[/tex]

Finally, the distance between the stations is 160.2 miles.

Final answer:

To convert the inequality 5x - 5y ≥ 70 to slope-intercept form, we solve for y to get y ≤ −x − 14, which is most appropriately represented as option (b.) y ≤ x − 14 after rearranging terms.

Explanation:

To write the inequality 5x − 5y ≥ 70 in slope-intercept form, we need to solve for y. We start by isolating the y-term on one side of the inequality.

First, we subtract 5x from both sides: −5y ≥ 70 − 5x

Next, we divide each term by -5 (remembering to reverse the inequality symbol because we are dividing by a negative number): y ≤ (70/−5) + (5x/−5)

y ≤ −14 − x

Finally, we write x before the constant to follow conventional form:

y ≤ −x − 14

Comparing this result to the multiple-choice options, we can see that none of them exactly match the form we derived. However, we can rewrite our inequality as y ≤ x − 14 by multiplying through by -1 (which will not change the inequality because we are not dividing or multiplying the inequality itself, just rearranging the terms).

Therefore, the correct answer is (b.) y ≤ x − 14.

Taylor has 6 stickers, as Jessica's 48 stickers are 8 times Taylor's amount. Also, after certain actions, we can conclude that Jenny initially had 14 chocolates.

Jessica has 48 stickers, which is 8 times as many stickers as Taylor has. To find out how many stickers Taylor has, we need to divide the number of Jessica's stickers by 8:

Therefore, Taylor has 6 stickers.

In a similar problem, Jenny has some chocolates. After eating two chocolates and giving half of the remainder to Lisa, Lisa ends up with 6 chocolates. To determine the number of chocolates Jenny started with, we multiply the number Lisa received (6) by 2 and then add the 2 chocolates Jenny ate:

Hence, Jenny initially had 14 chocolates.

-12/3*(-8+-4^2-6)+2

-4^2 = 16

-12/3*(-8+16-6)+2

-8+16-6 = 2

-12/3*(2) +2

-12/3 * 2 =-8

-8 +2  = -6

The value of the given expression -12/3×[-8+(-4)²-6]+2 will be -6.

An expression is a combination of some mathematical symbol such that arithmetic operator and variable such that all are constrained and create an equation.

In other meaning, expression is very useful to determine the end or root value of constraint.

For example 3x +5y

The constraint of expression is represented as = or <, >.

Given the expression  -12/3×[-8+(-4)²-6]+2

By division and opening square root

⇒ -4×[-8+ 16 -6]+2

By addition

⇒ -4×[ -8 + 10]+2

⇒ -4× 2 + 2

⇒ -8 + 2

⇒ -6

Hence "The value of the given expression -12/3×[-8+(-4)²-6]+2 will be -6".

To find the number of rows filled by the Springfield fifth graders, divide the total number of students by the number of students in each row.

Explanation:

To find the number of rows filled by the Springfield fifth graders, you need to divide the total number of students by the number of students sitting in each row. In this case, there were 35 students in each row.

To calculate the number of rows, divide the total number of students by the number of students in each row:

Number of rows = Total number of students / Number of students in each row

Since the total number of students is not mentioned in the question, I cannot provide a specific answer. However, if you have that information, you can substitute it into the formula to find the number of rows.

To find Jimmy's speed, divide the distance he ran by the time taken. Speed = Distance/Time. which is m/t.

To find Jimmy's speed, we use the formula Speed = Distance/Time.

Therefore, Jimmy's speed, in miles per minute, is m/t.

For example, if Jimmy ran 5 miles in 10 minutes, his speed would be 0.5 miles per minute (5 miles / 10 minutes = 0.5 miles per minute).

Answer:

B (-2, 3)

Step-by-step explanation:

Just took quiz

The coordinates of B before translated to B' are (-2,3).

Translation is a term used in geometry to describe a function that moves an object a certain distance.

In translation, a figure can move upward, downward, right, left or anywhere in the coordinate system.

In translation, only the position of the object changes, its size remains the same.

For  the given situation,

Triangle ABC is translated to image A’B’C’.

In this translation, A(5, 1) maps to A’(6,-2).

In translation, the distance between A' and A in the coordinate system is same as B'B and C'C.

Let A(x_1,y_1) = (5,1) and A'(x_2,y_2) = (6,-2)

⇒ x_1 - x_2 = 5 -6

⇒ -1

⇒  y_1 - y_2 = 1- (-2)

⇒ 3

The coordinates of B’(-1,0)

So, the coordinates of B is

⇒ x= (-1 -1) = -2

⇒ y= (0 + 3) =3

Thus coordinates of B are (-2,3).

Hence we can conclude that the coordinates of B before translation are (-2,3).

Yes, 5 grams (5 g) is greater than 508 milligrams (508 mg).

To compare the two quantities, grams (g) and milligrams (mg),  

Make sure they are in the same unit.

Since 1 gram is equal to 1000 milligrams, we convert the given values into the same unit, which is milligrams (mg).

5 grams (5 g)

508 milligrams (508 mg)

To compare them, we need to convert 5 grams into milligrams:

5 grams × 1000 milligrams/1 gram = 5000 milligrams

Now, we have both quantities in milligrams:

5 g = 5000 mg

508 mg = 508 mg

Since 5000 mg is greater than 508 mg, we can conclude that 5 grams (5 g) is greater than 508 milligrams (508 mg).

Therefore, 5 grams is indeed greater than 508 milligrams.

Answer:

The gambler came with $31.

Step-by-step explanation:

Let x be the initial amount.

At the end of the first race at the track he had doubled his money, that is 2x.

He bet $31 on the second race and tripled the money he came with.

Means 3x.

He bet $51 on the third race and quadrupled his original bankroll that is 4x.

He bet $84 on the fourth race and lost it, but still had $40 left.

Summing all the values, we get;

[tex]4x-84=40[/tex]

=> [tex]4x=40+84[/tex]

=> [tex]4x=124[/tex]

=> x = 31

Hence, the gambler came with $31.

The temperature at 5000m is -15 degrees Celsius.

To determine the temperature outside an airplane that has climbed to an altitude of 5000m, we start with the initial ground temperature at the airport, which is 10 degrees Celsius. For every 1000m increase in altitude, the temperature drops by 5 degrees Celsius. We can calculate the temperature decrease over 5000m by multiplying the temperature change per 1000m (5 degrees) by the number of 1000m segments in 5000m (which is 5).

The calculation is as follows:

Temperature drop per 1000m = 5 degrees Celsius

Number of 1000m segments in 5000m = 5

Total temperature drop = 5 segments * 5 degrees/segment = 25 degrees Celsius

Temperature at 5000m = Ground temperature - Total temperature drop

Temperature at 5000m = 10 degrees Celsius - 25 degrees Celsius

Temperature at 5000m = -15 degrees Celsius

Therefore, the temperature outside an airplane that climbs to an altitude of 5000m is -15 degrees Celsius.
