Answer:

x = 30.5 degree

Step-by-step explanation:

take angle x as reference angle

using sin rule

sin x = opposite / hypotenuse

sin x = 3.4 / 6.7

sin x = 0.507

x = [tex]sin^{-1} (0.507)[/tex]

x = 30.46

x = 30.5 degree

Answer:

36 green apples

Step-by-step explanation:

Red=40%

Green =x%

40/100 × 60apples

0.4×60

24red apples

so 60-24

36green apples

Answer:

b) 36.

Step-by-step explanation:

Justicemoya35 has an excellent answer, but I will provide a slightly different approach!

According to the word problem, the box contains 60 apples.

If 40% of the apples are red, then 60% of the apples are green.

As I mentioned before, there are 60 apples; 60% of the 60 apples are green.

This means we have the find 60% of 60.

We can find the percentage of a number by using this formula:

60% OF 60

[tex]\frac{is}{of} =\frac{percent}{100}[/tex]

[tex]\frac{x}{60} =\frac{60}{100}[/tex]

Now that I've correctly set up the problem, we cross multiply, then divide the products.

[tex]60*60=3600[/tex]

[tex]100*x=100x[/tex]

[tex]3600/100x=36[/tex]

[tex]x=36.[/tex]

Therefore, 36 apples are red.

Answer:

x = -26.67 (this is rounded the real answer is 26.6666...)

Step-by-step explanation:

180 - (46 + 36) = 82 (the measure of the last angle)

82 = (2 - 3x)

(subtract two from both sides)

80 = (-3x)

(divide both sides by -3)

-26.67=x

Answer:

$33.10

Step-by-step explanation:

$28.96 + $2.56 = $31.52

$31.52 * .05 = $1.576 (round up) $1.58

$31.52 + $1.58 = $33.10

Answer:

Step-by-step explanation:

Total without sales tax

Snorkel  =         28.96

Ear Plugs            2.56

Total                  31.52

Sales tax = 5% of Total  = 5/100 *31.52

Sales tax = 1.58 Rounded.

Total purchase = 33.10

Step-by-step explanation:

Answer:

Adjacent, b = 45 units

Step-by-step explanation:

Let the length of sides of the triangle be;

Given the following data;

Hypotenuse, c = 53 units

Opposite, a = 28 units

To find the missing side (adjacent), we would have to apply Pythagorean' theorem.

From Pythagorean theorem;

c² = a² + b²

Substituting into the formula, we have;

53² = 28² + b²

2809 = 784 + b²

Rearranging the equation (collecting like terms), we have;

b² = 2809 - 784

b² = 2025

Taking the square root of both sides, we have;

b = √2025

Adjacent, b = 45 units

Answer:

JK = 21 ft

Step-by-step explanation:

To find JK = x, apply Trigonometry function.

Reference angle = 65°

Opposite side = JK = x

Adjacent side = KL = 10 ft

Apply TOA:

Tan 65° = Opp/Adj

Tan 65° = x/10

Multiply both sides by 10

10*Tan 65° = x

21.4450692 = x

x = 21 ft (nearest feet)

Answer:

There's is a 25% chance on having all 6 births be girls. There is a 50-50 chance of a boy nor a girl. However, it is possible.

The probability of having 6 ​girls will be 1/64.

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

In a family with 6 ​children, excluding multiple​ births.

Then the probability of having 6 ​girls will be

Leaving out the third gender, let's suppose that there is an equal chance of having a girl or a boy.

Any child can be either a boy or a girl, with each having equal probability of = 1/2

Each of these blank spaces can be filled in 2 ways : B and G (denoting 'B' and 'G' respectively)

Probability of first blank being a ''G' is = 1/2

and second blanks too being a “G” is = 1/2

Thus, probability of each blank individually being a “G” = 1/2

Thus, probability of all being a “G” = (1/2) (1/2)  (1/2) (1/2) (1/2)* (1/2) = (1/2)6 = 1/64

Thus, probability of 6 children being all 6 girls = 1/64

Answer:

45 degree

Step-by-step explanation:

3x - 9 + 24 + 30 = 180 degree (being sum of interior angles of a triangle)

3x + 45 = 180

3x = 180 - 45

x = 135/3

x = 45 degree

Answer:45 độ

Step-by-step explanation:

3x - 9 + 24 + 30 = 180 độ (là tổng 3 góc của tam giác)

3x + 45 = 180

3x = 180 - 45

x = 135/3

x = 45 độ
