Answer:

7.85km

Step-by-step explanation:

Given data

Radius= 6km

θ= 75°

Arc length = 2πr (θ/360)

substitute

Arc length = 2*3.142*6 (75/360)

Arc length = 2*3.142*6*0.2083

Arc length = 7.85 km

Hence the length of the arc is 7.85km

Answer:

Let the triangle be ABC

Let AB = 14 and BC = 8

By Pythagoras theorem ,

                   [tex]AC^2 = AB^2 + BC^2 = 14^2 + 8^2 = 196 +64 = 260\\AC = \sqrt{260}\ inches[/tex]

Answer:

6 < x < 22

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

14 - 8 < x < 14 + 8

6 < x < 22

Answer:

C)

Step-by-step explanation:

A)  8 + 24 ÷ 12 x 4 = 8 + 2 x 4 = 8 + 8 = 16

B)  8 + 24 ÷ (12 x 4) = 8 + 24 ÷ 48 = 8 + 1/2

C)  32 ÷ 48 = 2/3

D)  8 + 2(4) = 16

Answer:

C

Step-by-step explanation:

-2x+6 [tex]\geq[/tex]-4

     -6   -6

-2x [tex]\geq[/tex]-10

divide both sides by -2

-2/2=-1

-10/2=-5

-5*-1=5

x[tex]\geq[/tex]5

x is greater than 5 so the number should be larger than 5 or equal to 5.

Answer:

Angle A would be 40°

Step-by-step explanation:

The sum of all angles of a triangle is 180° always.

So, the sum of 80° , 11x - 4 and 15x would be 180°

80° + 11x - 4 + 15x = 180°

80 - 4 + 11x + 15x = 180°

76 + 26x = 180

26x = 104

x = [tex]\frac{104}{26}[/tex]

x = 4

Since angle A is 11x - 4, its measure would be

(11 x 4) - 4

44 - 4

40.

Answer:

35 pounds of $8.00 tea and 15 pounds of $6.00 tea

Step-by-step explanation:

Let x represent the pounds of tea of the $8 kind. 8x would represent the total cost of that type of tea. We can also say 50 - x is the pounds of tea of the $6 kind, so 6(50 - x) is the total cost of that type of tea. 50 * 7.4 represents the total cost of all the tea, and the expression 8x + 6(50 -x) would also represent the same thing. We can write this as an equation,

8x + 6(50 -x) = 50 * 7.4

simplify,

8x + 300 - 6x = 370

2x + 300 = 370

and solve.

2x = 70

x = 35

This means there is 35 pounds of the $8 kind.

We can subtract that from 50 to find,

50 - 35 = 15,

15 pounds is the amount of the $6 kind.

The probability of a freshman being a boy is 3/37.

What is probability?

Probability is a branch of mathematics that deals with the study of randomness and uncertainty in events. It is the measure of the likelihood or chance that an event will occur. Probability is expressed as a number between 0 and 1, where 0 indicates that the event will not occur and 1 indicates that the event will occur with certainty.

The total number of students is:

3 + 1 + 4 + 2 + 7 + 9 + 6 + 5 = 37

The number of freshman boys is 3. Therefore,

P(Freshman Boy) = number of freshman boys / total number of students

P(Freshman Boy) = 3/37

Hence, the probability of a freshman being a boy is 3/37.

Answer:

is the answer .......

Answer:

C

Step-by-step explanation:

Using Pythagoras' identity in right triangle BPO

with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )

OP² + 4² = 5²

OP² + 16 = 25 ( subtract 16 from both sides )

OP² = 9 ( take the square root of both sides )

OP = [tex]\sqrt{9}[/tex] = 3

Answer:

28.5 ft^3

58.3 m^3

Step-by-step explanation:

volume of a pyramid = 1/3 x length x width x height

Perimeter of a pyramid = 4 x length

10.1 = 4 x length

length = 10.1 / 4 = 2.525

1/3 x (2.525 x 2.525 x 13.4) = 28.5 ft^3

1/3 x (6.1 x 6.1 x 4.7) = 58.3 m^3

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero
