Is the answer of 18 + pie rational or irrational?

Use law of sines:

Cos(x) = adjacent/ hypotenuse

cos(x) = 8.8/13

X = arcsin(8.8/13)

X = 47.396 degrees

Rounded to the nearest tenth = 37.4 degrees

Answer:

its b

Step-by-step explanation:

Answer:

Step-by-step explanation:

2) a(a + b) + b(a - b) - 2ab / a² - b²

= a² + ab + ab - b² - 2ab / a² - b²

= a² - b² / a² - b²

= 1

3) [x - 1/(x - 1)(x - 2)] + [x - 2/(x -2)(x - 3)]

= (1 / x - 2) + (1 / x - 3)

= x - 3 + x - 2 / (x - 2)(x - 3)

= 2x - 5 / x² - 5x + 6

Answer:

$43.40

Step-by-step explanation:

First, you would have to find out how much was discounted. To find this, you multiply $62.00 (the total) by 30% (the discount sale). You will end up getting $18.60. Finally, you can subtract $18.60 from the original total which was $62.00 to get $43.40 after the discount.

623 to 1 significant number = 600

14.71 to 1 significant number = 10

0.54 to 1 significant number = 0.5

answer:

[tex]\tt \dfrac{600-10}{0.5}=1180[/tex]

Answer:

3/171

Step-by-step explanation:

The problem can be simplified into finding probability that Anna and Becky select 12 or 24 or 36 which are less than 40 and multiples of 3 and 4.

Probability of Anna selecting 12 = 1/9

Probability of Becky selecting 12 = 1/19

Probability of Anna and Becky selecting 12 = 1/9 * 1/19 = 1/171

Probability of Anna and Becky selecting 12 or 24 or 36 = 3* 1/171 = 3/171

Answer:

Whats the square unit???

Step-by-step explanation:

Answer:

First you need to find at least two dimensions of the triangle containing a side length of x. The triangle of the top can be used for that. The hypothenuse for the 7,3 triangle is [tex]\sqrt{58}[/tex].

Now we can use the other triangle with sides of x,[tex]\sqrt{58}[/tex], and a hypothenuse of 9 to find x.

x^2 + [tex]\sqrt{58}^2[/tex] = 9^2

simplify

x^2 + 58 = 81

subtract 58 from both sides

x^2 = 23

x = [tex]\sqrt{23\\}[/tex]

and since this radical cannot be simplified further that is your answer.

Step-by-step explanation:

Step-by-step explanation:

Pythagoras.

c² = a² + b²

c being the Hypotenuse (the side opposite of the right angle).

so, the length of the rectangle is the Hypotenuse of the right-angled triangle on the top :

length² = 7² + 3² = 49 + 9 = 58

length = sqrt(58)

the diagonal of the rectangle is again the Hypotenuse of the right-angled triangle of length (sqrt(58)), width (x) and diagonal (9) of the rectangle.

so, we have

9² = sqrt(58)² + x² = 58 + x²

81 = 58 + x²

23 = x²

x = sqrt(23)

Answer:

10

Step-by-step explanation:

Take the bottom number from the smaller triangle and multiply by 10 (just like they did for the 3 which is how they turned it into 15)

Answer: B) y=-3x+2.

Step-by-step explanation:

+2 is where the line touches on the y axis. and for -3. you find 2 points and you go from 1 point to the other. the points i got were. (0,2) (2,-4). i went down 6 times, and to the right 2. that’s a fraction 6/2. and then simplify. 2 can go into 6 three times, and can go into 2 once. 3/1. since there’s a 1 underneath it’s just 3. and since you went down. it’s is negative. so y=-3x+2 is your answer.

Answer:

x = 11

Step-by-step explanation:

(3x + 28) + (5x + 52) + ( 2x - 10) = 180

(3x + 5x + 2x) + (28 + 52 - 10) = 180

10x + 70 = 180

10x = 180 - 70

10x = 110

x = 11

Answer:

x= 11

Step-by-step explanation:

(3x + 5x) + (5x+52) + (2x-10)= 180 (sum of anglea in a triangle)

10x+80-10= 180

10x+70=180

10x=180-70

10x=110

x=110÷10

x=11

Answer:

C

Explanation:

A: 2 in. by 2 in. by 1 in. = 4 cubic inches

B: 1 in. by 1 in. by 1 in. = 1 cubic inches

C: 2 in. by 1.5 in. by 0.5 in. = 1.5 cubic inches

D: 3 in. by 0.5 in. by 1.5 in. = 2.25 cubic inches

Therefore, the answer is C.

A linear relationship is an equation that has a constant slope

The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x

A linear equation can take any of the following forms:

y = mx + b

y - y1 = m(x - x1)

Ax + By = c

Any form different from the above forms is not a linear equation

Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x

The cost of the chicken and the grain are illustrations of linear programming

The minimized cost is 12¢

Represent the number of chicken with x and the number of grain with y.

So, the objective function is

Min Z = 10x + y

The constraints are not given.

So, the function cannot be minimized.

However, assume the minimum feasible values of x and y are (1,2), the minimized cost would be:

Z = 10  * 1 +  2

Z = 12

Hence, the minimized cost is 12¢

Step-by-step explanation:

Any number that satisfies 335<x<345

Answer:

x = 10

Step-by-step explanation:

All angles in a triangle must add up to 180. We know one angle is 68 and another is 90 because there is a right angle (which are always 90).

180 = 90 + 68 + (2x + 2)

180 = 158 + (2x + 2).      subtract 158 from both sides

22 = 2x + 2.     subtract 2 from both sides

20 = 2x.       divide both sides by 2

10 = x

Answer:

x = 10

Step-by-step explanation:

2x + 2 + 68 + 90 = 180

2x + 160 = 180

2x = 20

x = 10

Answer:

2

Step-by-step explanation:

this might be the rong answer

Answer:

The answer is 5/6.

Step-by-step explanation:

Lets start with a=1.

a+1=2, which is the denominator. (1/2)

Taking the same number as numerator, now, consider a=2.

a+1=3, denominator.(2/3)

Now, let a=3.

a+1==4, denominator for a=3. (3/4)

If continued a becomes equal to 4.

a+1=5, which is also the denominator. (4/5)

Now, since the denominator is 5, let a=5.

a+1=6, which will become the denominator. (5/6)

Thus the series follows a pattern of a/a+1.

Answer:

5/4

Step-by-step explanation:

Let's put the unknown value as X

To solve this equation, we must solve for x

First we need to isolate x, which means we need to get it by itself.

To do this, we must subtract 3/4 on both sides since it is being added.

This gets rid of 3/4 on the first side and changes the second side to whatever 2+3/4 is

This leaves us with x=5/4

Therefore, your answer is 5/4.

Answer:

10 students

Step-by-step explanation:

Given :-

50% younger than 10

1/20 (or 5%) are 10

1/10 (or 10%) are older than 10 but younger than 12

Remaining students = 100% - 50% - 10% - 5%

= 35%

= 70 students

Total students

=> 7T/20 = 70

=> 7T = 1400

=> T = 200

10 year old students

= T x 5%
