Answer is :115

The size of angle x is 115.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the figure,

The whole complete angle is 360.

This means,

164 + 81 + x = 360

Solve for x.

164 + 81 + x = 360

245 + x = 360

x = 360 - 245

x = 115

Therefore,

The size of angle x is 115.

What is the inverse function (equation) of f(x) = 6x - 5 ?

Answers

Step-by-step explanation:

Given

f(x) = 6x - 5

f^-1(x) = ?

Let

y = f(x)

y = 6x - 5

Interchanging the roles of x and y we get

x = 6y - 5

6y = x + 5

y = ( x + 5 ) / 6

So therefore f^- 1(x) = (x + 5) / 6

A car travels a distance of 190 miles in a time of 3.4 hours.
What is its average speed rounded to 1dp?

Answers

Answer:

55.9 mph

Step-by-step explanation:

190/3.4 = 55.88 mph rounded to one dp = 55.9 mph

A car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

What is average speed ?

Average speed is speed is the total distance traveled by the car in a particular time of interval.

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

We have,

Distance [tex]=190[/tex] miles

Time[tex]= 3.4[/tex] hours

So, Using the above given formula,

Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]

                          [tex]=\frac{190}{3.4}[/tex]

                         [tex]=56[/tex] miles per hour

So, the average speed of car is [tex]56[/tex] miles per hour which is find out using the above given formula.

Hence, we can say that if a car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then  its average speed will be  [tex]56[/tex] miles per hour.

Answers

Answer:

7.9 m

Step-by-step explanation:

Use the Pythagorean theorem: a²+b²=c²

This formula can be used to solve a side of any right (90°) triangle.

c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)

So, c = 32m.

Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:

31² + b² = 32²

961 + b² = 1024 Subtract 961 from both sides to get b² by itself.

b² = 63

√b² = √63  Square root both sides to get b by itself.

b = 7.93725

Three bananas and two pears cost 95p.
Five bananas and three pears cost £1.51
Find the cost of ten bananas and ten pears.​

Answers

Answer:

Cost of ten bananas and ten pears is  £ 3.90

Step-by-step explanation:

As three bananas and two pears cost  95 p  and  five bananas and three pears cost  £  1.51  or  151  p ,

subtracting former from latter, we get

two bananas and one pear cost  151 p  −  95 p  =  56 p

and doubling four bananas and two pear cost  56 p × 2 = 112 p

Hence, one banana costs  112 p  −  95 p  =  17 p .

and two bananas cost  17 p  ×  2  =  34 p

and hence one pear costs  56 p  −  34 p  =  22 p

Hence cost of ten bananas and ten pears is  

10  ×  17 p  +  10  ×  22 p  =  170 p  +  220 p  =  390 p  =  £ 3.90
