We know that :

v = 12 miles/hour

s = 36 miles

So :

[tex] t = \frac{s}{v} = \frac{36}{12} [/tex]

Answer:

tan(47)=53/z

Step-by-step explanation:

Using trig ratio tan(x)=O/A

there x is the angle of elevation, O is the side opposite the angle (the lighthouse) and A is the side adjacent the angle (distance between boat and bottom of lighthouse)

Therefore, tan(47)=53/z

[tex]\\ \tt\hookrightarrow tan47=\dfrac{H}{B}[/tex]

[tex]\\ \tt\hookrightarrow tan47=\dfrac{53}{B}[/tex]

[tex]\\ \tt\hookrightarrow B=\dfrac{53}{tan47}[/tex]

Answer:

x²-25=?

Step-by-step explanation:

x² is known as a positive number.A positive number is any number more than 0

so we can there fore assume it's 4 so 4-25 no we can't so we divide

4÷25=0.16 it is a decimal.

Answer:

s = 71

j = 23

71 = 3j+2

71 - 2 = 3j

39 = 3j

j = 23

Answer:

j=23

s=71

Step-by-step explanation:

Here we have two parallel lines lines( UB and DK).

And we have another line, called a transversal that intersects( crosses) both parallel line. Doing so creates the following angles,

So now we look at the graph

First, we know that 3j+2 and s are vertical angles since they are across of each other. So they are equal to each other so let look at another angle first.

3j+s and 71 are Alternate Interior Angles since they lie inside the transversal and are across from each other.

Since they are Alternate Interior Angles, they are equal.

So we set them equal to each other.

[tex]3j + 2 = 71[/tex]

Subtract 2 from both sides

[tex]3j = 69[/tex]

Divide both sides by 3

[tex]j = 23[/tex]

The value of j is 23.

Know to find S, we know s is equal to 3j+2, which when we plug in 23 for j, we get 71.

So s=71

Answer:

Shirt:8 ; jsans:16.

Step-by-step explanation:

Let’s shorten these terms: shirt=s ; jean=j.

3s+3j=72

4s+2j=64 => =2j=64-4s => j=(64-4s):2 => j=32-2s

3s+3j=72 => (instead of j we write 32-2s=> 3s+3*(32-2s)=3s+96-6s=72

=> -3s=72-96
-3s=-24

s=24:3

s=8.
=> j=32-2s => j= 32-16 => j=16.

Answer:

B

Step-by-step explanation:

4 meters above. So 4 will not be negative, this eliminates C and D.

16 is definitely negative. So that eliminates C and D again.

< the number on the left of this is smaller than the right

> the number of the right of this is bigger than the left

4 is larger than -16

4>-16

Step-by-step explanation:

Finding the HCF can help a great deal, so in this case the HCF between 16 and 72 is 8.

16/8 = 2

72/8= 9

Therefore the answer is

Answer:

Quesnel Lake:Lake Baikal=.31

Quesnel Lake:Great Slave Lake=.82

Step-by-step explanation:

1 foot = .3048 meters

Lake Baikal: 5369 ft. = 1636.4712 m

Great Slave Lake: 2015 ft. = 614.172 m

Quesnel Lake: 506 m

Quesnel Lake:Lake Baikal

[tex]506 \div 1636.472 = .31[/tex]

Quesnel Lake:Great Slave Lake

[tex]506 \div 614.172 = .82[/tex]

bc Answer: They form an obtuse triangle

Step-by-step explanation:

the length of one side must be greater than the difference and less than the sum of the lengths of the other two sides. In this case the third side must be greater than 3 and less than 31. 3(squareroot) 55 is 22.25 so it fits.

Answer:

7,912.8 inch³ of aluminum is needed to make 70 metal balls

Step-by-step explanation:

r = 3 inches and π = 3.14

single aluminum ball, 113.04 inch³ of aluminum

113.04 inch³ of aluminum is used for 1 ball, then we multiply 70 with this value to determine the aluminum needed for 70 such balls.

Answer/Step-by-step explanation:

1. x = -3.6

Add 1 on both sides.

18x = 23x + 18

Subtract 23x on both sides.

Combine like terms.

Divide the answer.

-5x = 18

x = -3.6

2. x = 11/3 (2.66666...)

Add 5 on both sides.

6x = 3x + 11

Subtract 3x on both sides.

Combine like terms.

Divide the answer.

3x = 11

x = 11/3

3. x = 23

Subtract 12 on both sides.

5x = 6x - 23

Subtract 6x on both sides.

Combine like terms.

Divide the answer.

-x = -23

x=23

(that's all.)

Answer:

135 cm

Step-by-step explanation:

[tex] \cos(43) = \frac{75}{y} [/tex]

[tex]y = \frac{75}{ \cos(43) } [/tex]

[tex]y = 135[/tex]

Answer:

y ≈ 102 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos43° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{75}{y}[/tex] ( multiply both sides by y )

y × cos43° = 75 ( divide both sides by cos43° )

y = [tex]\frac{75}{cos43}[/tex] ≈ 102 cm ( to 3 sf )

Answer:

Step-by-step explanation:

Hi there!

We want to find the least common multiple (LCM) of 12 and 18

One easy way to do that is to split up the numbers into one of their factor pairs, find the factor pairs between the numbers we just split apart, and then keep on going, until we only get prime numbers (numbers that only have 1 and itself as multiples)
Let's start with 12.

There are multiple ways to multiply to get to 12, but we can use 3 and 4 for example

12= 3*4

4 is 2 * 2  

Substituting 2*2 for 4, 12 is equal to 2*2*3

Now for 18.

18 can also be split up multiple ways; one way would be 9 and 2

18 = 2*9

9 is 3*3

Substitute 3*3 for 9.

18=2*3*3
Now look at 2*2*3; 2 shows up twice in that string of numbers

In 2*3*3, 3 shows up twice in that string of numbers

We multiply the numbers based off of the highest number of times that they occur
In other words, we will multiply 2 * 2  and 3 * 3 together
2 * 2 * 3 * 3 = 4 * 9 = 36
The LCM of 12 and 18 is 36

Hope this helps!
