Answer:

D. x = 10, m<TRS = 60

Step-by-step explanation:

1. Approach

To solve this problem, one will set up an equation to model the problem. The problem gives that the sum of two angles (m<QRT and m<TRS) equals the third angle (m<QRS). Additionally, the measure of one of the angles is given (m<QRS = 122), and the expression for the values of the other two angles are given, (m<QRT = 7x - 8), (m<TRS = 6x). One can form an equation, and solve it to find the unknown. Finally, one can then substitute the values of the unknown, into the expression to find the measure of the angle.

2. Solve for (x)

One can set up an equation based on the given information, then solve the equation.

m<QRT + m<TRS = m<QRS

Substitute,

(7x - 8) + (6x) = 122

Simplify

7x - 8 + 6x = 122

13x - 8 = 122

Inverse operations

13x - 8 = 122

      +8    +8

13x = 130

/13      /13

x = 10

3. Find (m<TRS)

Now that one has the value of (x), one can substitute the value into the given expression for the (m<TRS), and solve to find the value.

m<TRS = 6x

x = 10

m<TRS = 6(10)

m<TRS = 60

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

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:

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

(x+9)/(x+1)

Step-by-step explanation:

The parent function of the functions of the form f(x)=√x−a+b is f(x)=√x . Note that the domain of f(x)=√x is x≥0 and the range is y≥0 . The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.

Answer:

7500

Step-by-step explanation:

Let's call that 'whole' a variable 'x'.

Since 75 is 1% of the whole, we can write this out with numbers and symbols, remembering that 1% of a number is 0.01 times that number

75 = 0.01*x

From there, you can divide both side of the equals sign by 0.01 to find x.

75=0.01x

7500 =x

Answer:

7,500

Step-by-step explanation:

1% of 7,500 is 75

Formula : (Number x 100)/Percent Number = (75x100)/1 = 7,500/1 = 7,500
