Final answer:

The average speed of the canoe is 1.5 mph.

Explanation:

To find the average speed of the canoe, we need to calculate the time it takes for the canoe to go both upstream and downstream. Let's start with the time it takes to go upstream:

Distance = 3 miles
Speed of canoe = Speed in still water - Speed of current = 8 mph - 1 mph = 7 mph

Time = Distance / Speed = 3 miles / 7 mph = 0.429 hours

Now, let's calculate the time it takes to go downstream:

Distance = 3 miles
Speed of canoe = Speed in still water + Speed of current = 8 mph + 1 mph = 9 mph

Time = Distance / Speed = 3 miles / 9 mph = 0.333 hours

Finally, we can find the average speed of the canoe by dividing the total distance traveled (6 miles) by the total time taken (4 hours): average speed = total distance / total time = 6 miles / 4 hours = 1.5 mph.

The statements true about x are all the statements other than first one. x ∈ B, x ∉ C, x ∈ A∪B, x ∈ A∪C and x ∈ A∩B.

Venn diagram is a diagram denoting two or more sets which is drawn using circles inside a rectangle where the part where the two circle meet denotes the intersection of two sets.

Given is a Venn diagram.

The blue portion of the circle is A.

Pink portion is B.

Green portion is C.

x is inside the blue circle.

So x belongs to A. x ∈ A

So the statement 1 is not true.

x is also inside the pink portion.

So, x ∈ B

x is not inside the green portion.

So, x ∉ C

A ∪ B consists of all the elements inside A and all the elements inside B.

So x ∈ A∪B

Since x ∈ A, x will be included in A ∪ C.

So, x ∈ A∪C

A ∩ B consists of elements which are both in A and B.

Since, x ∈ A and x ∈ B, x ∈ A∩B

Hence all the statements other than first are true.

Answer:

24/25

Step-by-step explanation:

cosin=cah adjacent over hypotenuse

"The correct ratio representing the cosine of ∠L in ΔKLM is [tex]\(\frac{7}{25}\).[/tex]

In right-angled triangle ΔKLM, where ∠M is 90°, the cosine of ∠L is defined as the ratio of the adjacent side to the hypotenuse.

The adjacent side to ∠L is KM, and the hypotenuse is LK.

 Given that LK = 25 and KM = 7, the cosine of ∠L is calculated as follows:

[tex]\[ \cos(\angle L) = \frac{\text{Adjacent side (KM)}}{\text{Hypotenuse (LK)}} = \frac{7}{25} \][/tex]

This ratio [tex]\(\frac{7}{25}\)[/tex] represents the cosine of ∠L in ΔKLM."

6

Step-by-step explanation:

1/2 = 0.5

2/5 = 0.4

60 × 0.5 = 30

60 × 0.4 = 24

30 + 24 = 54

60 - 54 = 6

Answer:

6

Step-by-step explanation:

Louis build 1/2 of the toy and the total of the toy is 60

Which means

1/2×60=30

Valentina build 2/5 toy

2/5×60

120/5

24

So to determine the amount left

It will be

Total-(Louis+Valentina)

60-(30+24)

60-(54)

60-54

6

So the amount left is 6

Answer:

351.7

Step-by-step explanation:

The first number after the decimal is the tenth. Round up if the second number is 5 or above, round down if the second number is below 5.

Answer:

351.7

Step-by-step explanation:

Look at the tenths space which is one place to the right of the decimal. It is a 6.

Then look at the number behind it: if the number behind is is 4 or less the number in front stays the same, if the number behind it is 5 or more the number in front goes up one more

so there is an 8 behind the 6, so you round the 6 to a 7

Given:

Right triangle.

Base = 10

Hypotenuse = 26

To find:

The missing side length

Solution:

Let the missing side length be x.

Using Pythagoras theorem:

In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

[tex]10^2+x^2=26^2[/tex]

[tex]100+x^2=676[/tex]

Subtract 100 from both sides.

[tex]100+x^2-100=676-100[/tex]

[tex]x^2=576[/tex]

Taking square root on both sides.

[tex]x=24[/tex]

The missing side length of the right triangle is 24.

Comment on solving inequalities

In general, you solve these the same way you would an equation. The difference comes when you use an operation that changes ordering. Multiplying or dividing by a negative number does that, for instance.

Consider ...

  2 > 1.

Multiply both sides by -1, and it is true only if you reverse the comparison:

  -2 < -1

(There are other operations that change ordering, but this is the one you will likely run across most often.)

Answer:

8.3%

Step-by-step explanation:

The rate of return on initial investment is 8.34%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the investment is $6,000 and valued at $6,500. The rate of the return will be calculated as,

Rate of return = ( 6500 - 6000) / 6000

Rate of return = 800 / 6000

Rate of return = 8.34%

Therefore, the rate of return on initial investment is 8.34%.

For 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.  

It is defined as the change in values of a dependent variable with respect to the independent variables.

W have:

Rate of burning for thicker = h/4

Rate of burning for thinner= h/2

remaining part = h - ht/4

remaining part = h - ht/2

h - ht/4 = 3(h - ht/2)

After solving for t:

t = 8/5 hours

or

t = 96 minutes

Thus, for 96 minutes the candles were burning if two candles of equal height start to burn simultaneously.
