Step-by-step explanation: Notice that we have a 30° angle and we're given that the side opposite the 30° angle has a length of h and the side adjacent to the 30° angle has a length of 18.

Remember than [tex]tan =[/tex] [tex]\frac{opp}{adj}[/tex] so we can setup the equation tan 30° = h/18.

Solving for h, we multiply both sides of the

equation by 18 and we have (18)(tan 30°) = h.

From here, we enter this into our calculator to get 10.3923 or 10.4.

Instead of using trigonometry here, we could have also noticed that this is a special right triangle, a 30° - 60° - 90° triangle, which means that the long leg is √3 times the length of the short leg, so we could have setup an equation to find the value of h. Either way should be acceptable.

Step-by-step explanation:

24s3 is the greatest common factor of 24 S3 12 s4 and 18s.

Answer:

13

Step-by-step explanation:

We know that a^2+b^2 = c^2  where a and b are the legs and c is the hypotenuse

5^2 + 12^2 = c^2

25+144 = c^2

169 = c^2

Taking the square root of each side

sqrt(169) = sqrt(c^2)

13 =c

Answer:

1.08915145

Step-by-step explanation:

First of all do 39 x 52, which equals 2028. Then to do the second part of the equation we move the two bottom numbers place value up by one giving us 38 x 49 which is 1862. And then we put 2028 divided by 1862 into our calculators and get the answer as 1.08915145.

The order of Rotational symmetry is 2 (option B) for the given figure.

It is basically the number of times we obtain the initial(or same) figure in a single rotation of 360°.

The rotational symmetry of a shape demonstrates that when an object is rotated on its axis, the form of the object examines the same. Many geometrical shapes emerge to be symmetrical when they exist rotated 180 degrees or with some angles, clockwise or anticlockwise. Some of the examples exist as squares, circles, hexagons, etc.

If we rotate the picture by 90°or 270°, then it wont match the initial figure.

If we rotate the picture by 180° from initial, it will match the figure.

If we further rotate it by 180°( full 360° completed) , it will again match.

Hence, it matches 2 times in a single rotation.

Therefore it has rotational symmetry of order 2.

Answer:

B

Step-by-step explanation:

answer is slope =2

use formula y2-y1 over x2-x1

two points of graph is (6,6) and (1,-4)

since 6 and -4 are both y, we take 6-(-4) over 6-1

we get 2

The fish's length will affect the mean because the new mean length will be less than 14.2 inches. That is option A.

Mean is defined as the sum of all the data values divided by the count of values in a data set.

What a new value is added to a data set such as the group of fishes, it will affect the fish mean by reducing it to less than its former mean value which is 14.2 inches.

Therefore, the fish's length will affect the mean because the new mean length will be less than 14.2 inches.

Answer:

x = -5

Step-by-step explanation:

A vertical line is a line that goes up and down.  It is of the form x = constant

To go through (-5,6) is has to have the value of the x coordinate

x = -5

Answer:

r = 5

Step-by-step explanation:

Side 1: 7

Side 2: 2 + r

To determine r, we subtract 2 from both sides to get the following:

Side 1: 5

Side 2: r

5 and r are the same, so 5 must equal 5.

Therefore, r = 5.

Answer:

0.62kg

Step-by-step explanation:

Let

x = 40/kg coffee

y = 11/kg coffee

two equations can be derived from the question

x + y = 12 equation 1

40x + 11y = 114 (9.5 x 12)  equation 2

multiply equation 1 by 11

11x + 11y = 132 equation 3

subtract eqn 3 from eqn 2

29x = 18

divide both sides of the equation by 29

x = 0.62kg

Answer:

4 coats

Step-by-step explanation:

Let the cost of a pair of shoe be x.

Thus, 6 pairs would cost; 6x

Thus,1 coat will cost 6x.

2 pairs of jeans cost as much as 3 pairs of shoes.

Thus, 2 pairs of jeans will cost 3x.

4 pairs of socks cost as much as one pair of jeans.

If 2 pairs of jeans cost 3x

Then 1 pair will cost 3x/2 = 1.5x

Thus, 4 pairs of socks will cost 1.5x.

Thus, 1 pair of socks will cost 1.5x/4

Then, 64 pairs of socks will cost;

64 × 1.5x/4 = 24x

Earlier, we saw that 1 coat costs 6x.

Thus means that;

Number of coats to exchange for 64 pairs of socks = 24x/6x = 4 coats

2 * 10^7   You are to use a single digit. That's the 2 on the left. Then count what it takes to get the decimal between the 2 and the 3. It's 7

0.000136

Count the number of zeros. Add a minus 1. You want the number to be counted until you get minus 1 which is the number of powers after the 1.

1 * 10^-4

26837 becomes 2 * 10^4. 4 is the number of digits you have before you get to a number between 1 and 10.

0.0302 becomes 3 * 10^-(1 + 1) = 3 * 10^-2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

b = 3

Step-by-step explanation:

3(9+9b)=69+136

27+27b = 205

27b = 205-27

27b = 178

b = 178/27

*slaps face*

In the comments you said the "136" is "13b" so ok...

3(9+9b)=69+13b

27+27b = 69 + 13b

27+14b = 69

14b = 69-27

14b = 42

b = 3
