The airplane is 48 feet long in real dimensions.
To find out how long the airplane actually is, we can use the scale and input our amount of inches that it is measured by.
So, 1 inch equals to 6 feet.
Our model plane is 8 inches.
Now, we plug it in.
8 inches = 6(8)
8 inches = 48 feet
Therefore, the length of the real airplane is 48 feet.
48 feet
Answer:
48 feet
Step-by-step explanation:
Let's create a proportion using the following setup.
inches/feet=inches/feet
We know the scale is 1 inch to 6 feet. We also know that the plane is 8 inches long, but we don't know how many feet long it is, so we can say x feet.
1 inch/6 feet= 8 inches/ x feet
1/6=8/x
Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Multiply the denominator of the first by the numerator of the second.
1*x=6*8
x=6*8
x=48
Add appropriate units, in this case: feet.
x= 48 feet
The actual airplane is 48 feet long.
when a transversal cuts a pair of parallel lines, name one angle that is formed
Answer:
Angle pairs formed by parallel lines cut by a transversal When two parallel lines are given in a figure, there are two main areas: the interior and the exterior. When two parallel lines are cut by a third line, the third line is called the transversal.
Step-by-step explanation:
Answer:
Step-by-step explanation:
If a transversal intersects two parallel lines, then each pair of interior angles on the same side of the transversal is supplementary, i.e. they add up to 180°.
A house painter used the equation y = 6.2x to determine the number of gallons of paint, y, needed to paint a number of houses, x. Which table represents the equation?
Answer:
(2,12.4) , (5,31), (8,49.6)
Step-by-step explanation:
To Solve this problem, let substitute value of x from given table into equation y = 6.2x and determine value of y .
For x = 2
y = 6.2x
=> y = 6.2*2 = 12.4
__________________________________________
For x = 5
y = 6.2*5
=> y = 31
__________________________________________
For x = 8
y = 6.2*8
=> y = 49.6
__________________________________________
Thus, second table represent the equation.

Answer:
False --> 1011 > 1100
True --> 110 + 111 == 1101
50 --> 1010 x 101
13 --> 110 + 111
17 --> 1010101 / 101
Step-by-step explanation:
This solution is achieved by calculating the binary operations, then finding either their values or the validity of their statements.
1011 > 1100 is the same as 11 > 12, which is false.
110 + 111 == 1101 is the same as 6 + 7 = 13, which is true.
1010 x 101 is the same as 10 x 5, which is 50.
110 + 111 is the same as 6 + 7, which is 13.
1010101 / 101 is the same as 85 / 5, which is 17.

Find the volume of a right circular cone that has a height of 4.5 ft and a base with a
diameter of 14.2 ft. Round your answer to the nearest tenth of a cubic foot.
Answer:
The volume of the cone is:
237.6 cubic feet.Step-by-step explanation:
The volume of a cone is:
Volume of a cone = (1/3) PI * r^2 * hWhere:
r = radius.
h = height.
Since the exercise provides the diameter but not the radius, you simply have to divide the diameter in two:
Radius = diameter / 2 Radius = 14.2 ft / 2 Radius = 7.1 ft / 2Now we proceed to replace in the formula:
Cone volume = (1/3) PI * (7.1 ft)^2 * 4.5 ft Cone volume = 237.5515285 ft^3 Cone volume = 237.6 ft^3QUICK ANSWER THIS!!!

An angle, θ, is in standard position. The terminal side of the angle passes through the point (4, 5).
Find cosθ.
Answer:
cos Θ = [tex]\frac{4}{\sqrt{41} }[/tex]
Step-by-step explanation:
Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by
h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )
h = [tex]\sqrt{41}[/tex]
In relation to Θ, 4 is adjacent and 5 is opposite, thus
cos Θ = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4}{\sqrt{41} }[/tex]

If an angle has a measure of 1 radian, then the arc intercepted by that angle has an arc length equal to the radius of the circle.
Answer: True
Step-by-step explanation: the angle subtends, s, divided by the radius of the circle, r. One radian is the central angle that subtends an arc length of one radius (s = r). Since all circles are similar, one radian is the same value for all circles.
The given statement is correct. If an angle has a measure of one radian, the arc intercepted by that angle has an arc length equal to the radius of the circle.
What is meant by radian and radius?Simply put, a Radian is a unit of measurement for angles that is based on the radius of a circle. This means that if we imagine wrapping the length of the radius around a circle, the angle formed at the center of the circle by this arc is equal to 1 Radian. Radians, like degrees, are a type of angle measurement. One radian is equal to the angle formed when the radius of the circle is equal to the arc opposite the angle. So, in the diagram above, the angle is one radian because the arc AB is the same length as the radius of the circle.Therefore,
Because the Latin word for length is spatium, arc lengths are denoted by s.
Length of an Arc = θ × r,
Where θ exists in radian.
Length of an Arc = θ × (π/180) × r,
Where θ exists in degree

Answer:
a) A triangle which the angles ratio is 1 : 2 : 3 is a 30º - 60º - 90º right triangle.
b) The shortest side is opposite to the shortest angle. So, we can calculate it using sin 30º.
[tex]$\text{sin}(30\º)=\frac{\text{Opposite side to x}}{19} $[/tex]
[tex]$\frac{1}{2} =\frac{\text{Opposite side to x}}{19} $[/tex]
[tex]$\text{Opposite side to x}= 9.5$[/tex]
Answer:
see explanation
Step-by-step explanation:
(a)
Sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6 to find the value of one part of the ratio.
180° ÷ 6 = 30° ← value of 1 part of the ratio, thus
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
Thus the triangle is right
-----------------------------------------
(b)
The sides of a 90°- 60°- 30° triangle are in the ratio
2 - [tex]\sqrt{3}[/tex] - 1 ( where 2 represents the hypotenuse )
Thus the other 2 sides of the triangle are
19 ÷ 2 = 9.5 , and
9.5 × [tex]\sqrt{3}[/tex] ≈ 16.45
The shortest side is 9.5

Identify the slope and y-intercept of the line.
y = 6x-5
Answer:
slope = 6
y-intercept = -5
Step-by-step explanation:
The equation is in slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept
Let's find the slope:
The slope is the number being multiplied by x.
y = mx + b
y = 6x - 5
Therefore, the slope is 6.
Let's find the y-intercept:
The y-intercept is the last number in the equation.
y = mx + b
y = 6x -5
Therefore, the y-intercept is -5.

Step-by-step explanation:
We see that in the left column, the integers increase by one at a time and that in the right column, the integers decrease by two at a time. Therefore, the rate of the increasing and decreasing of numbers is the same throughout the table so this line is linear.
Also, you could use desmos, a graphing calculator which is free on your computer to plot these points and to see that the line is linear.

Angle θ is in standard position and terminates in quadrant II. If tanθ = -15/8, then cscθ = _____.
Answer:
csc Θ = [tex]\frac{17}{15}[/tex]
Step-by-step explanation:
Given
tan Θ = - [tex]\frac{15}{8}[/tex] = [tex]\frac{opposite}{adjacent}[/tex] ← of a right triangle , then
hypotenuse h² = 15² + 8² = 225 + 64 = 289 ( square root both sides )
h = [tex]\sqrt{289}[/tex] = 17
Using the identity
csc x = [tex]\frac{1}{sinx}[/tex]
sin Θ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{15}{17}[/tex]
Since Θ is in second quadrant then sinΘ and csc Θ > 0, thus
csc Θ = [tex]\frac{1}{\frac{15}{17} }[/tex] = [tex]\frac{17}{15}[/tex]
