A train traveled at a constant speed for six hours and traveled a distance of 408 miles. What is the best estimate of the number of miles the train could travel in 2.5 hours? *

Answer:

Extreme Flow Rates = 730 gallons per minute | 550 gallons per minute

where,

Maximum Flow Rate = 730 gallons per minute

Minimum Flow Rate = 550 gallons per minute

Step-by-step explanation:

The extreme values of a quantity are the minimum and the maximum acceptable  values of that quantity. These values can be found by adding and subtracting the allowed variation from the target value, for maximum and minimum value, respectively. Therefore:

Extreme Flow Rates = Target Flow Rate ± Allowed Variation in Flow Rate

Extreme Flow Rates = 640 gallons per minute ± 90 gallons per minute

Extreme Flow Rates = 640 gallons per minute + 90 gallons per minute | 640 gallons per minute - 90 gallons per minute

Extreme Flow Rates = 730 gallons per minute | 550 gallons per minute

where,

Maximum Flow Rate = 730 gallons per minute

Minimum Flow Rate = 550 gallons per minute

Step-by-step explanation:

Well, if 1 gallon of gas = 1 hour then

2 hours would be 2 gallons so only 11 gallons of gas would be left in the tank and

13 hours would be 13 gallons, so 0 gallons of gas would be left in the tank

Answer: D and J

Step-by-step explanation:

Subtract 17.56 from both sides and divide by 5 to get the answer of D. 2.52

3x + 6 = 9

subtract 6 from both sides

3x = 3

x = 1

Answer:

False

Step-by-step explanation:

Unit Rate Definitions Unit rate is used to compare quantities in which the second quantity is one. Common examples of unit rate would include, miles per hour earnings per hour cost per gallon.

How much of something per 1 unit of something else. Examples: • 100 cars pass by in 2 hours. The unit rate is 50 cars per hour.

Answer:

False

Step-by-step explanation:

it could be 5 cats : 6 dogs.

Unit rates can be unequal too.

Answer:

the mean is 50

Step-by-step explanation:

add up all the numbers which equals 300 then divide but the amount of numbers in this is 6 so that gives you 50

Answer:

50 is the mean

Step-by-step explanation:

When it ask for mean it ask you to add up all the numbers and divide by how many numbers their are. Their 6 numbers added together to make the total of 300.

49+51+49+51+51+49 = 300

300 / 6 = 50

Answer:

.125 of a mile

Step-by-step explanation:

If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.

Change the 3/8 to a decimal

3/8 = 0.375 of a mile

Since there were 3 runners divide the total distance by 3

0.375/3 = 0.125

Each runner ran 1/8 of a mile or 0.125 of a mile.

Answer:

[tex]a=\frac{K}{4+9b}[/tex]

Step-by-step explanation:

[tex]K=4a+9ab[/tex]

Switch sides:

[tex]4a+9ab=K[/tex]

Factor out a:

[tex]a\left(4+9b\right)=K[/tex]

Divide both sides by: [tex](4+9b)[/tex]

[tex]\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}[/tex]

[tex]a=\frac{K}{4+9b}[/tex]

Step-by-step explanation:

T3ST1CALZ

Answer:

Step-by-step explanation:

If an elephant charged 13.3 meters in 15 seconds, to calculate the distance charged by the elephant in one minute, the following steps will be arried out.

15 seconds = 13.3 meters

1minute (60 seconds) = x

cross multiply

15 * x = 13.3 * 60

15x = 798

Divide both sides by 15

15x/15 = 798/15

x = 53.2metres

Hence the elephant will charge 53.2 meters for 1 minute

Answer:

PQ = 1 ft

QR = 4 ft

Step-by-step explanation:

From the picture attached,

Segment PR has been divided into two parts by a point Q.

Length of segment PR = 5 feet

Length of segment PQ = (15x - 2) ft

Length of segment QR = (5x + 3) ft

Since, PR = PQ + QR

5 = (15x - 2) + (5x + 3)

5 = 20x + 1

20x = 4

x = [tex]\frac{4}{20}[/tex]

x = 0.2

PQ = 15x - 2

     = 15(0.2) - 2

     = 3 - 2

     = 1 ft

QR = 5x + 3

     = 5(0.2) + 3

     = 1 + 3

     = 4 ft

Answer:

(x,y)=(-1,-4)

Step-by-step explanation:

-4x + y = 0

+4x         +4x

y=4x

-5x - 2y = 13

+5x          +5x

-2y = 5x+13

-2(4x) = 5x+13

-8x=5x+13

-5x -5x

-13x/-13=13/-13

x=-1

Thus:

y=4x

y=4(-1)

y=-4

The answer would be -7/12

Step-by-step explanation:

What you would do is

a/b×c/d=ac/bd

this would be the formula

so what you would do is -7 (which is the numerator X the other numerator which equals -7 times 1= -7

then you would do 2 X6= which is 12 so the answer would be 7/12 because you can't simplify it anymore

Answer:
