Answer:

45°

Step-by-step explanation:

Angles on a straight line add up to 180°.

135 + x = 180

x = 180 - 135

x = 45°

Answer:

48 cm

Step-by-step explanation:

Here Is a trapezium and a square, The lengths of the parallel sides of the  trapezium are 10 cm and 14 cm, The height of the trapezium is 12 cm. The area of  the square is equal to the area of the trapezium. Work out the perimeter of the  square.

Solution:

The area of the trapezium is given by:

A = (1/2)(a + b)h

where h is the height of the trapezium = 12 cm, a and b are the parallel sides. Given that a = 10 cm, b = 14 cm, hence:

A = (1/2)(10 + 14)12 = 144 cm²

Area of trapezium = Area of square

Area of square = 144 cm²

Area of square = length * length = length²

length² = 144 cm²

length = √144 = 12 cm

Perimeter = 4 * length = 4 * 12 cm = 48 cm

Answer:

B) 42 units squared

Step-by-step explanation:

12 * 7 = 84

84 / 2 = 42

Answer:

1 whole flower pot

Step-by-step explanation:

Given that:

Quart of soil Adia has = 58

Quart of soil to fill a whole flower pot = 54

The pot Adia can fill. With the soil he has :

Quart of soil Adia has / Quart of soil to fill a whole flower pot

= 58 / 54

= 1.074 pots

= 1 flower pot

The set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a set of ordered pairs:

{(0,1.2),(3,2),(-1.2,3), (4, -2),(1,-1.2),(1,2,4)}

We know there are four main types of mapping that are:

One to one, one to many, many to one, and many to many.

In the case of one to one, and many to one. the relation is a function but in the case of one to many and many to many relations is not a function.

As we can see in the set of ordered pairs the x values are repeated which is also not a property of a function hence it is not representing the function.

Thus, the set does not represent a function, option (D) the set is a not function since each element in the range has a different element in the domain is correct.

Answer:

square root of ten so b.

Step-by-step explanation:

The solution is:

Number of students who like only tennis and football = 2

Number of students who like only tennis and baseball = 5

Number of students who like only baseball and football = 12

The intersection of two sets is the set of all those elements which are common to both of the sets.

here, we have,

Solution:

Let students who likes tennis be represented by set T.

Let students who likes football be represented by set F.

Let students who likes baseball be represented by set B.

Given that

Number of students who likes tennis that is n(T) = 18

Number of students who likes football that is n(F) = 25

Number of students who likes tennis and football = n( T ∩ F ) = 10

Number of students who likes tennis and baseball = n( T ∩ B ) = 13

Number of students who likes football and baseball = n( F ∩ B ) = 20

Number of students who likes all three sports = n(T ∩ F ∩ B ) = 8

Number of students who likes none of the sports = 9.

Determining number of students who like only tennis and football:

number of students who like only tennis and football = Number of students who likes tennis and football - Number of students who likes all three sports

so number of students who like only tennis and football

= n( T ∩ F ) - n(T ∩ F ∩ B )  

= 10 – 8

= 2

Determining number of students who like only tennis and baseball:

number of students who like only tennis and baseball = Number of students who likes tennis and baseball - Number of students who likes all three sports

so number of students who like only tennis and baseball

= n( T ∩ B ) - n(T ∩ F ∩ B )  

= 13 – 8

= 5

Determining number of students who like only baseball and football:

number of students who like only baseball and football = Number of students who likes baseball and football - Number of students who likes all three sports

so number of students who like only baseball and football

= n( B∩ F ) - n(T ∩ F ∩ B)  

= 20 – 8

= 12

Summarizing the result :

number of students who like only tennis and football = 2

number of students who like only tennis and baseball = 5

number of students who like only baseball and football = 12.

How many students like only tennis and​ football? How many students like only tennis and​ baseball? How many students like only baseball and​ football?

Answer: A

Step-by-step explanation:

r = j + 3

We subtitube r to find j,

r = 9          j = 9 + 3 = 12

r = 15         j = 15 + 3 =18

r = 21         j = 21 + 3 = 24

Answer:

7 seconds

Step-by-step explanation:

You would get 49 from doing -784 divided by -16 then you do the square root of 49 which is 7

ANSWER= 7 seconds

The time taken by the pebble to hit the ground will be = 7 seconds

Expression we get when operations such as addition , subtraction , multiplication , division , are operated upon on variable and constants.

Equation of height as a function of time = h(t) = - 16 (t^2)

cliff is at a height of = 784 feet

comparing both the above equation , we get

-16 (t^2) = 784

t^2 = 49

t = 7 seconds

The time taken by the pebble to hit the ground will be = 7 seconds
