[tex] \times area = area \: of \: trapezium + area \: of \: rectangle \\ = ( \frac{1}{2} \times h(a + b)) + (l \times w) \\ = ( \frac{1}{2} \times (11 - 6) \times (20 + 8)) + (20 \times 6) \\ = 70 + 120 \\ = 190 \: {m}^{2} [/tex]

Answer:

Step-by-step explanation:

Since this is a right triangle, we will use a right triangle trig identity to solve our problem. The side opposite the reference angle A is given as 5, and the side adjacent to the reference angle is given as 7. The trig ratio that uses the sides opposite and adjacent is the tangent ratio:

[tex]tanA=\frac{5}{7}[/tex]

Hit the 2nd button on your calculator then the tan button which displays:

[tex]tan^{-1}([/tex]

Enter 5/7 after that open parenthesis and hit = to get that

A = 35.54°

Answer:

x and y = 19

Step-by-step explanation:

sin 45/x = sin90/19[tex]\sqrt{2}[/tex]

19[tex]\sqrt{2}[/tex]×sin45=sin90x

x=19

Pythagorean theorem for y

[tex]y^{2}[/tex]=(19[tex]\sqrt{2}[/tex])^2 - 19^2

y^2= 722 - 361

y^2= 361

y=19

The answers seem kinda weird to me so...

Answer:

C(F) means Celcius temperature value from Fahrenheit temperature

Step-by-step explanation:

C(F) is Mathematically interpreted as C of F, this means the value of C obtained for a given F value, that is we have a relation, expression or formular exoressed in terms of F which can be used to obtain the Value of C for a given value of F by making necessary substitution.

Here the relation or expression is c(f)=5/9(f-32).

Hence, once we are given a particular F value, we can substitute that into the equation and obtain the corresponding C temperature value.

Answer:

x = 0.75

Step-by-step explanation:

Answer:

for 50 pulls, 12.5 blue socks, but you cant have half of a sock so we say 12

for 1000 pulls, 250 blue socks

for 10,000 pulls, 2500 blue socks

Step-by-step explanation:

First we add 5, 7 and 8 to find the total number of socks, 5+7=12 and 12+8 = 20

5 is the amount of blue socks, so

5/20 * how many pulls are conducted is the probability for blue socks

7 is the amount of pink socks, so

7/20 * how many pulls are conducted is the probability for pink socks

and

8 is the amount of yellow socks, so

8/20 * how many pulls are conducted is the probability for yellow socks

Find half of 3/8:

1/2x3/8 = 3/16

Answer:

Tan <A = 4/3

Cos <A = 3/5

Sin <A = 4/5

Step-by-step explanation:

From the diagram given

Hypotenuse AB = 10

Adjacent = 6

Opposite = 8 (side facingc<A)

According to SOH CAH TOA

Tan <A = Opposite/adjacent

Tan <A = BC/AC

Tan <A = 8/6

Tan <A = 4/3

For Cos <A;

Cos <A = adj/hyp

Cos <A = 6/10

Cos <A = 3/5

For sin<A:

Sin <A = opp/hyp

Sin <A = 8/10

Sin <A = 4/5

Answer:

0.25

Step-by-step explanation:

Hope it helps, sense it’s centered around 0.25 then the parameter would be 0.25

To It’s centered around 0.25 then the parameter would be 0.25.

We have given,

Suppose that many large samples were taken from a population and the sample proportion centered around 0.25

We have to determine which of the given is most likely the population parameter.

A sample means from any distribution. We could have a left-skewed or a right-skewed distribution.

To It’s centered around 0.25 then the parameter would be 0.25

Therefore option A(0.25) is correct

To It’s centered around 0.25 then the parameter would be 0.25.

Step-by-step explanation:

Answer:

imagine a triangle

one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.

remember the pythagoras stuff

so

(slantheight)² = radius² + height²

or finally:

slantheight = squareroot (radius² + height²)

Answer:

6

Step-by-step explanation:

y = f(x)

6 = a |1 |

6 = a. 1

a = 6/1

a = 6

Answer:

[tex] \displaystyle a = 6[/tex]

Step-by-step explanation:

we are given a absolute value function

[tex] \displaystyle f(x) = a |x| [/tex]

we want to figure out the value of a

since we are a point which is on the function we can figure out a by using the point i.e (1,6) this point tell us when x is 1 f(x) is 6 thus

substitute:

[tex] \displaystyle 6= a \cdot |1| [/tex]

absolute value of any integer is positive therefore,

[tex] \displaystyle 6= a \cdot 1[/tex]

simplify multiplication:

[tex] \displaystyle 6= a [/tex]

hence,

the value of a is [tex]\underline{\quad 6 \quad}[/tex]

Answer:

45°

Step-by-step explanation:

This is a isosceles triangle and also a right triangle, so it means it have an 90° ingernal angle and the other two internal angles have the same value. Remember that the sum of the internal angles of a triangle is always 180°, so:

180° -90° = 90°

90°/2 = 45°

Answer:

Actually,I don't understand the que but I will try.

Step-by-step explanation:

Supplementry it means the pair of angle that sum if 180° similarly, complimentry angle sum is 90°
