Can someone help me with this question please !
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

Answer:
Step-by-step explanation:
If you think money, a question like this won't confuse you.
Which would you rather owe your parents
13 dollars or
10 dollars
The answer is obvious, isn't it? Most people would rather owe 10 dollars rather than 13.
The minus sign is the same as debt. - 13 is less than - 10. You are further and further in the hole when you owe 13 dollars than 10.
So the inequality is not correct. The answer is no.
So still with money
-13<- 11
13 > 11
you would rather have 13 dollars in your pocket than 10.
You would rather owe -10 dollars than - 13
Solve the equation -10X +1 + 7X = 37
Answer:
X = -12
Step-by-step explanation:
-10X + 1 +7X = 37
-10X + 7X + 1 = 37 {Add the like terms}
-3X + 1 = 37 {Subtract 1 form both sides}
-3X + 1 -1 = 37 -1
-3X = 36 {Divide both sides by (-3)}
[tex]\frac{-3x}{-3}=\frac{36}{-3}\\\\[/tex]

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.
(2,12.4) , (5,31), (8,49.6)
Answer:
(2,12.4) (5,31) (8,49.6)

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.
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]

Answer:
y - 6= -5/4(x+4)
Step-by-step explanation:
The point slope form of the equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y -6 = -5/4(x - -4)
y - 6= -5/4(x+4)

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.

write 0.126126126... as a fraction
Answer:
x = 126/999
Step-by-step explanation:
Let x = .126126126 repeating
Multiply each side by 1000
1000x = 126.126126126 repeating
subtract the first equation from the second
1000x = 126.126126126 repeating
- x = .126126126 repeating
999x = 126
Divide each side by 999
999x/999 = 126/999
x = 126/999
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^3i need help please answer with explantation

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]

Answer:
Linear
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.

TRUE or FALSE
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
