A submarine dives 51 3/5 meters below the surface of the water in 4 minutes. how many meters does the submarine dive each minute? NO LINKS!
A: 12 9/10
B: 12 3/4
C: 206 2/5
D: 47 3/5

Answers

Answer:

a

Step-by-step explanation:

51 3/5 = 258/5

258/5 / 4 = 12.9 (meters the submarine dives each min)

now we have to find out what 12.9 is as a fraction!

12.9= 12 9/10 because .9 is equal to 9/10, and 12. equals 12!

Unicorns love eating jelly beans! If a unicorn eats 410.7 ounces of jelly beans 6 times a day, how many ounces does it eat in one day?

Answers

Answer:

2464.2

Step-by-step explanation:

you multiply 410.7 by 6 to get this

The ounces of jellybean eaten in a day is required.

The amount of jellybean the unicorns eats in one day will be 2464.2 ounces.

The ounces of jellybean eaten at one time is 410.7 ounces

The number of times jellybean is eaten during one day is 6 times.

[tex]1\ \text{time}=410.7\ \text{ounces}[/tex]

So, for 6 times

[tex]6\ \text{times}=6\times 410.7=2464.2\ \text{ounces}[/tex]

What is the slope of the line that is perpendicular to the line that passes through the points (-1,3) and (2,-4)?

Answers

Hey there! Remember that perpendicular lines are the negative reciprocal to the original slope. With that in mind, the best way to find the slope is by using equation m=y2-y1/x2-x1, so then if we plug this in we get:

-4-3/2-(-1)

As -4 is our y2, -3 is our y1, 2 is our x2, and -1 is our y1.

You should get -7/3, that’s the original slope. Since this is a perpendicular line we MUST FLIP it and CHANGE THE SIGN.

So our FINAL answer would be: 3/7

The condition which cannot be met for the numerical example a < b is the third condition a > 0 and b < 0.

What are Inequalities?

Inequalities are expressions which are written on both sides separated by inequality symbols like <, >, ≤ and ≥.

The given numerical example is a < b.

When a > 0 and b < 0,

possible values of a are 1, 2, 3, ............

possible values of b are -1, -2, -3, .............

There is never a chance to get the positive values of a < negative values of b.

Hence the condition which is not met is a > 0 and b < 0.

i need step by step explanition if you can. paper depot is delivering 952 cases of paper today.300 of the cases are plain white paper twenty-eight trucks are being loaded with an equal number of cases of paper. how many cases will each truck carry

Answers

Answer:

34

Step-by-step explanation:

We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.

For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].

So, the answer is [tex]\boxed{34}[/tex] and we're done!

Step-by-step explanation:

Enter the ratio as a fraction in lowest terms 14 minutes to 18 minutes

Answers

Answer:

Part A is 7/16 of the whole
Part B is 9/16 of the whole

Solution:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 14 + 18 = 32

Part A = 14 and Part B = 18 are numerators for each fraction.

The fractions are then:
14/32 and 18/32

Meaning:
Part A is 14/32 of the whole
Part B is 18/32 of the whole

Reducing the fractions, it is also true that:
Part A = 7/16 of the whole
Part B = 9/16 of the whole

Answer:

Step-by-step explanation:

Data were recorded for a car’s fuel efficiency, in miles per gallon (mpg), and corresponding speed, in miles per hour (mph). Given the least-squares regression line, , what is the fuel efficiency for a speed of 60 mph?

3.65 mpg
33.90 mpg
36.52 mpg
38.55 mpg

Answers

The least-squares regression line equation gives the line that approximate the relationship between the variables in the fuel efficiency data

The fuel efficiency when the speed is 60 mph is approximately 38.55 mpg.

Reason:

The given least-squares regression line equation is presented as follows;

ln(Fuel Efficiency) = 1.437 + 0.541 × ln(speed)

Required:

The value of the fuel efficiency for a speed of 60 mph.

Solution:

The general form of the least-squares regression line equation is [tex]\hat y[/tex] = a + b·x

Where, in the current question, we have;

[tex]\hat y[/tex] = The predicted value = ln(Fuel Efficiency)

a = The y-intercept = 1.437

b = The slope = 0.541

x = The input value = ln(speed)

When the speed = 60 mph, we have;

ln(Fuel Efficiency) = 1.437 + 0.541 × ln(60) = 3.65204040816

Therefore;

[tex]Fuel \ Efficiency = e^{(1.437 + 0.541 \times ln(60))} \approx 38.55[/tex]

The fuel efficiency when the speed is 60 mph ≈ 38.55 miles per gallon

∠ A = 150°

∠ FCE and ∠ C are vertically opposite angles and are congruent , then

∠ C = 150°

∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°

∠ ECB = 180° - ∠FCE = 180° - 150° = 30°

∠ E = 180° - (30 + 45)° ← sum of angles in a triangle

∠ E = 180° - 75° = 105°

∠ CBE and ∠ D are same- side interior angles and sum to 180° , then

∠ D = 180° - 45° = 135°

Answer:

[tex]x = 26 \frac{1}{3} \\ [/tex]

Step-by-step explanation:

x = 2y - 1

x - 2y = -1 ________(1)

x + y = 40________(2)

(2) - (1)

[tex]x + y - (x - 2y) = 40 - ( - 1) \\ x + y - x + 2y = 40 + 1 \\ 3y = 41 \\ y = \frac{41}{3} \\ y = 13 \frac{2}{3} \\ [/tex]

y = 13 2/3

[tex]x + y = 40 \\ x + 13 \frac{2}{3} = 40 \\ x = 40 - 13 \frac{2}{3} \\ x = 40 - \frac{41}{3} \\ x = \frac{3(40) - 41}{3} \\ x = \frac{120 - 41}{3} \\ x = \frac{79}{3} \\ x = 26 \frac{1}{3} \\ [/tex]
