Step-by-step explanation:
To find the area of the rectangle:
l x w
6 x 4 = 24
To find area of triangle:
1/2(bh)
to find the base of the triangle you subtract 6 from 9:
9 - 6 = 3
So 1/2 (3 x 4)
1/2 (3 x 4)
1/2 (12)
12 / 2 = 6
Area of whole figure:
You will now add 6 + 24 = 30

¿Cuál es la suma de los ángulos interiores del polígono mostrado a continuación?
The sum of interior angles of the given polygon is 900 degrees
How to calculate the sum of an interior angle of a polygon?The formula used to calculate the sum of an interior angle of a polygon is expressed as:
Sum of interior angles = ( n − 2 ) × 180 ∘
n is the number of sides
The number of sides of the given polygon is 7, hence;
Sum of interior angles = (7 − 2 ) × 180 ∘
Sum of interior angles = 5 × 180 ∘
Sum of interior angles = 900 degrees
Hence the sum of interior angles of the given polygon is 900 degrees

8. An automobile traveled 320 miles in 6 hours. What is its average speed?
Answer:
The automobile's average speed is 53.33 mph.
Step-by-step explanation:
Since average speed equals total distance traveled divided by the time of the travel we have:
d = 320 mi the distance traveled
t = 6 hr the time of the travel
v = average speed
v = d/t
v = 320/6
v = 53.33 mph
Answer:
about 53 miles per hour
Step-by-step explanation:
320/6 is 53.33 repeated
you divide 320/6 because you need to know how many miles you going in an hour

The diameter of a circle is 2 centimeters. What is the circle's area?
Answer:
3.14 cm²
Step-by-step explanation:
Given :-
Diameter = 2 cm
To Find :-
Area
Formula Required :-
Area (circle) = πr²
Solving :-
Area = 3.14 x 1 x 1
= 3.14 x 1
= 3.14 cm²
Solution :-
3.14 cm²
Solution:
We know that:
Diameter of circle = 2 cmRadius = Diameter/2Area of circle = πr²Finding the radius.
Radius = Diameter/2=> Radius = 2/2=> Radius = 1 cmFinding the area.
Area of circle = πr²=> Area of circle = 3.14 x 1²=> Area of circle = 3.14 x 1 = 3.14 cm²what is pi to the 30th digit (decimla place)

Which number is an irrational number?
Answer:
D. [tex]\sqrt[3]{16}[/tex]
Step-by-step explanation:
What is an irrational number?
❖ An irrational number is a number that cannot be written in fraction
form. They're also non-terminating and non-repeating decimals.
Determing Irrational or Rational
A.
The square root of 100 is 10 because 10 × 10 = 100. 10 can be written as a fraction of 10/1, so it's rational.B.
1/8 is already in fraction form, so it's rational.C.
-2.2675 is a terminating decimal, so it's rational.D.
The cube root of 16 is irrational because there is no exact number that multiplies itself 3x to get 16. Additionally, when you put the cube root of 16 in a calculator, you will get a mess of decimal digits, thus forming a non-repeating and non-terminating decimal.Helpp meeee question 2 pleaseee !!

Marlene rides her bike at a rate of 16 miles per hour. The time in hours that she rides is represented by the variable t, and the distance she rides is represented by the variable d. This relationship is modeled with distance d as a function of time t.
Which statements are true of the scenario? Select two answers..
Answer:
The equation t = d + 16 represents the scenario
Step-by-step explanation:
The independent variable, the input, is the variable d, representing distance. The distance traveled depends on the amount of time Marlene rides her bike. The initial value of the scenario is 16 miles per hour. so The equation t = d + 16 represents the scenario

Answer:
x = 20 degrees, angle ABC = 98 degrees
Step-by-step explanation:
The two inner angles sum up to 180 degrees. This is a general rule when you have two parallel lines and another line intersecting through both lines.
So angles ABC and DCB sum up to 180.
4x + 18 + 2x + 42 = 180
6x + 60 = 180
6x = 120
x = 20 degrees
Plugging this back in angle ABC,
4(20) + 18 = 98 degrees

What is the inverse of the trigonometric function in the graph? y = sinx y = cosx y = arcsinx y = arccosx
The inverse of the trigonometric function given in the graph is;
Option D; y = arc cosx
The graph is missing and so i have attached it.
To get the inverse of the trigonometric function, we need to first know what the trigonometric function is.From the graph, we see that;when x = 0, y = 1
when x = π, y = -1
when x = π/2, y = 0
Now, the equivalent of radian angle π when converted to degrees is; π = 180°
Thus; π/2 rad = 90°
Thus;
when x = 0°, y = 1
when x = 180°, y = -1
when x = 90°, y = 0
Now, let us look at the value of angle 0° for each trigonometric function sin, cos and tan.sin 0 = 0
tan 0 = 0
cos 0 = 1
Let us try angle 90°
sin 90 = 1
cos 90 = 0
tan 90 = ∞
The only trigonometric function that corresponds with the coordinates of the graph is y = cos x.The inverse of cos x is cos⁻¹x or arc cos x.
