A canoe traveled Downstream with the current and went a distance of 15 miles in three hours. On the return trip, the canoe traveled Upstream against the current. It took 5 hours to make the return trip. Find the rate of the current

Answer: 0.35km per minute

Step-by-step explanation:

Divide by 60 because it was in "km per HOUR".

Answer:

[tex]\frac{1}{26}[/tex] inches

Step-by-step explanation:

In order to solve this problem, we need to create a ratio.

Since we're looking for the rate per hour, we need to find how long it is from 10pm to 7:45am.

10pm + 2 hours = 12 AM

12 AM + 7.75 hours = 7:45 AM

So in total, it's 9.75 hours.

[tex]\frac{3}{8}[/tex] is the same as 0.375.

Our fraction will become [tex]\frac{0.375}{9.75}[/tex], which can simplify down to [tex]\frac{1}{26}[/tex].

Now we can create the proportion:

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

Now we solve for x by cross multiplying.

[tex]1\cdot1=1\\\\1\div26=\frac{1}{26}[/tex]

Answer:

34 units

Step-by-step explanation:

Given a rectangle TREC, with RC and ET being the diagonal both intersecting at the middle, then the following are true;

Let O be the point of intersection of RC and ET;

RO+OC = RC

Given the distance from point R to the middle as 2 x - 3, then RO = 2x-3 and if the distance from the middle point to point C is x + 7, then OC = x+7

Since they intersect in the middle, RO = OC

2x-3 = x+7

Collect like terms

2x-x = 7+3

x = 10

RO = 2x-3

RO = 2(10)-3

RO = 17

since RO = OC, then OC = 17units

Note that both diagonal RC and ET inyetsect at the middle O hence diagonal RC = ET = RO+OC

RC = ET = 17+17

RC = ET = 34units

Hence the length of ET is 34 units

Answer: (-3.5 + (-1.5))

Step-by-step explanation:

Given the expression :

The temperature in the morning was -3.5 °F. By noon, the temperature had dropped by 1.5 °F. Write an addition expression to represent this scenario.

Morning temperature : - 3.5°F

By Noon : change (drop) in temperature

Addition expression to represent the scenario :

A drop in temperature means a further reduction in the initial temperature level :

Addition expression :

(Morning temperature + ( - drop in temperature))

(-3.5 + (-1.5))

Answer:

  6 servings

Step-by-step explanation:

To find the number of servings, divide the total amount by the quantity per serving.

You can compute this using a calculator:

  5.333/0.875 ≈ 6.095 ≈ 6 servings

__

Or, you can do the mixed-number math:

  (5 1/3)/(7/8) = (16/3)(8/7) = 128/21 = 6 2/21 ≈ 6

There were 6 servings in the container.

Answer:

6

Step-by-step explanation:

6 is the answer.

This is not a function. The input 7 in set A maps to outputs -1 and -3 at the same time in set B, which is why we don't have a function.

For a function to be possible, each input must map to exactly one output only.

Answer:

The land not made up of farmland = 5 million acres

Step-by-step explanation:

Number of farms in Nebraska = 48000

Total acres of land used by Nebraska = 45 million acres

Total of the state covered = [tex]\frac{9}{10}[/tex] of the state

To find:

How many acres are not made up of farmland ?

Solution:

Given that [tex]\frac{9}{10}[/tex] of the state is covered by the farmland.

Total area in farmland = 45 million acres

It means that, Rest of the land is not made up of farmland.

First of all, let us calculate the total land of Nebraska then we will subtract the farmland from total, to find the land not made up of farmland.

That will be our answer.

Let the total land be = [tex]x[/tex] million acres.

As per the question statement:

[tex]\frac{9}{10}\ of\ x = 45\ million\ acres[/tex]

OR

[tex]\dfrac{9}{10}\times x =45\\\Rightarrow x = \dfrac{45\times 10}{9}\\\Rightarrow x = 50\ million\ acres[/tex]

Therefore, the land not made up of farmland = [tex]x[/tex] - 45 = 50 -45

5 million acres

Answer:

(3,-3)

Step-by-step explanation:

First you divide 2 out of the first equation and it turns into 5x+y=12.

Then you write one on top of the other so you can add them. It looks like:

5x + y = 12

-5x + y = -18

Then you add them together and the 5x's cancel each other out and you are left with 2y = -6

So then you divide both sides by 2 and get y = -3

Then you plug -3 into the second equation because it is simpler and get -5x - 3 = -18

So then you add three to both sides and get -5x = -15

And finally you divide both sides by -5 and get x=3

g = (pk + 7)/3

Greetings from Brasil...

According to the statement of the question, we can assemble the following system of equation

X = 7 + 3Y i

X + Y = 75 ii

So, multiplying ii by -1 and adding with i

X = 7 + 3Y

- X - Y = - 75

- Y = 7 + 3Y - 75

4Y = 68

Y = 17

for X we will use ii:

X + Y = 75

X + 17 = 75

X = 58

The smaller number is: 17

Answer:

length=16 and width = 8

Step-by-step explanation:

p= 2(length + width) ........ p= 48 m

width=length-8

48= 4 length-16

48 +16 = 4 length

Answer:

[tex]f^{-1}(x)=\frac{x+1}{6}[/tex]

Step-by-step explanation:

So we have the function:

[tex]f(x)=6x-1[/tex]

To find the inverse function, switch x and f(x), change f(x) to f⁻¹(x), and solve for f⁻¹(x). Therefore:

[tex]f(x)=6x-1[/tex]

Switch:

[tex]x=6f^{-1}(x)-1[/tex]

Add 1 to both sides:

[tex]x+1=6f^{-1}(x)[/tex]

Divide both sides by 6:

[tex]f^{-1}(x)=\frac{x+1}{6}[/tex]

And that's our answer :)

Step-by-step explanation:

From least to greatest: -10, -3, +1. From greatest to least: +1, -3, -10.

1st way: Just look at it.

2nd way: See which numbers are to the left of 0 on the number line. Those are your smaller (negative) numbers. The numbers that are on the right side of 0 are your bigger (positive) numbers.

Answer:

Order by value: On a number line, the integers to the left are less than the integers to the right. Order by magnitude: On a number line, the integers farther from zero have a greater magnitude. Least to greatest value: –10, –3, +1. Least to greatest magnitude: +1, –3, –10.

Step-by-step explanation:

Which did you include in your response? Check all that apply.

You can order by value.

You can order by magnitude.

Ordering from least to greatest value, the list is –10, –3, +1.

Ordering from least to greatest magnitude, the list is +1, –3, –10.

Answer:

22cm and 16 1/2 cm is the answer

Write the ratio as a fraction and multiply with each dimension

If a photograph is 8cm by 6cm, the new dimensions after enlarging the photograph by a ratio of 11:4 would be: 22 cm by 16.5 cm.

Given the following measurement of a photograph:

To enlarge the photograph using a scale factor of 11:4 (11/4), multiply the scale factor by each of the dimensions.

Thus:

Therefore, if a photograph is 8cm by 6cm, the new dimensions after enlarging the photograph by a ratio of 11:4 would be: 22 cm by 16.5 cm.
