Answer:
See answers below
Step-by-step explanation:
Given the ratio of three angles as 3:5:8
Total ratio = 3+5+8 = 16
Mean = x+y+z/3
80 = x+y+z/3
x+y+z= 240
To get x;
x =3/16 * 240
x = 45degrees
To get y;
y = 5/16 * 240
y = 5 * 30
y = 75degrees
To get z;
z = 8/16 * 240
z = 120 degrees
Fourth angle = 360 - (120+75+45)
Fourth angle = 360-240
Fourth angle - 120 degrees

Which of the decimals or fractions is not equal to 0.525 or 1/8
Answer:
0.18
Step-by-step explanation:
1/8 as a decimal is 0.125
1/8 un-simplified is 3/24
0.525 as a fraction is 21/40
So 0.18 is the only one that doesn't belong
0.18 is not equal to 0.525 or 1/8. Therefore Option (A) is the correct answer.
We need to find which of the decimals or fractions are not equal to 0.525 or 1/8.
How do convert decimals to fractions?The decimal numeral system is the standard system for denoting integer and non-integer numbers.
To convert decimal to fraction follow these steps
Step 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number).
Step 2: Remove the decimal places by multiplication. First, count how many places are to the right of the decimal. Next, given that you have x decimal places, multiply the numerator and denominator by [tex]10^{x}[/tex].
Step 3: Reduce the fraction. Find the Greatest Common Factor (GCF) of the numerator and denominator and divide both numerator and denominator by the GCF.
Step 4: Simplify the remaining fraction to a mixed number fraction if possible.
Now, from option (A)
0.18=18/100=9/25
From option (B)
0.125=125/1000=5/40=1/8
From option (C)
3/24=1/8
From option (D)
21/40=0.525
Therefore, option (A) is the correct answer.

When [tex]5\frac{2}{3}[/tex] is divided by 4 then the result will be [tex]\frac{17}{12}[/tex] in fraction form.
We have to divide the mixed fraction [tex]5\frac{2}{3}[/tex] by 4.
Let us convert the mixed fraction to improper fraction.
[tex]5\frac{2}{3}[/tex] = [tex]\frac{17}{3}[/tex]
Now divide the fraction [tex]\frac{17}{3}[/tex] by a whole number 4.
[tex]\frac{\frac{17}{3}}{4}[/tex]
When a fraction is divided by a whole number then the fractions denominator is multiplied with the whole number.
[tex]\frac{17}{3 \times 4}[/tex]
Simplifying further:
[tex]\frac{17}{12}[/tex]
Hence, when [tex]5\frac{2}{3}[/tex] is divided by 4 then the result will be [tex]\frac{17}{12}[/tex].

Step-by-step explanation:
When we talk of the domain, we are referring to the possible x-values
from the diagram, we can see that we have the x-values at -4 and 6
The dotted line means that -4 and 6 are in the domain
Thus, the two points represent the end and starting point of the domain
Writing this in interval notation, we have the representation as;

The DeJeu family plan to drive to Marietta, GA to Newark, NJ. The distance is about 880 miles and the majority of their trip will be on a highway, where they will travel at an average speed of 65 miles per hour. They are leaving at 7:30 am, and they plan to stop 3 times for 10 minutes each and once for 1 hour. What is the approximate travel time?
Answer:
[tex]10:02:24\ \text{pm}[/tex]
Step-by-step explanation:
d = Distance to travel = 880 miles
s = Average speed of the car = 65 mph
Time taken to cover the distance is
[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{880}{65}\\\Rightarrow t=\dfrac{176}{13}\ \text{h}=13.54\ \text{hours}[/tex]
Time the car stopped
[tex]3\times 10+60=90\ \text{minutes}=1.5\ \text{hours}[/tex]
Total time of the journey
[tex]13.54+1.5=15.04\ \text{hours}[/tex]
Converting [tex]0.04\ \text{hours}[/tex] to minutes
[tex]0.04\times 60=2.4[/tex]
So, the total time taken for the journey is [tex]15\ \text{hours and }2\ \text{minutes and }24\text{seconds}[/tex]
Time when they reach their destination
[tex]7:30+15:2.4\approx 10:02:24\ \text{pm}[/tex]

(Easy) For the following quadratic function, find the axis of symmetry, the vertex and the y-intercept. y = x^2 + 12x + 32
Answer:
see explanation
Step-by-step explanation:
Given a quadratic in standard form , y = ax² + bx + c ( a ≠ 0 ), then
The x- coordinate of the vertex, which is also the equation of the axis of symmetry is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = x² + 12x + 32 ← is in standard form
with a = 1, b = 12 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{12}{2}[/tex] = - 6
Substitute x = - 6 into y for corresponding y- coordinate
y = (- 6)² + 12(- 6) + 32 = 36 - 72 + 32 = - 4
Thus
equation of axis of symmetry is x = - 6
vertex = (- 6, - 4 )
To find the y- intercept , let x = 0
y = 0² + 12(0) + 32 = 32 ← y- intercept
The axis of symmetry is x = -6, vertex is (-6,-4) and y-intercept is 32.
Quadratic function:Important information:
The given quadratic function is [tex]y=x^2+12x+32[/tex].Substitute [tex]x=0[/tex] to find the y-intercept.
[tex]y=(0)^2+12(0)+32[/tex]
[tex]y=32[/tex]
The vertex form of a quadratic function is:
[tex]y=a(x-h)^2+k[/tex] ...(i)
Where a is constant, (h,k) is vertex and x=h is the axis of symmetry.
Adding and subtracting the square of half of coefficient of x, the given quadratic function can be written as:
[tex]y=x^2+12x+32+6^2-6^2[/tex]
[tex]y=(x^2+12x+6^2)+32-36[/tex]
[tex]y=(x+6)^2-4[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=1,h=-6,k=-4[/tex]
Therefore, the axis of symmetry is x = -6, vertex is (-6,-4) and y-intercept is 32.

find the distance between two points ( -1,1) and (2,-4)
Answer:
The distance between two points ( -1,1) and (2,-4) is:
[tex]d=\sqrt{34}[/tex] or d = 5.8 units.
Step-by-step explanation:
Given the points
(-1, 1)(2, -4)Finding the distance between (-1, 1) and (2, -4) using the formula
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
substitute (x₁, y₁) = (-1, 1) and (x₂, y₂) = (2, -4)
[tex]=\sqrt{\left(2-\left(-1\right)\right)^2+\left(-4-1\right)^2}[/tex]
[tex]=\sqrt{\left(2+1\right)^2+\left(-4-1\right)^2}[/tex]
[tex]=\sqrt{3^2+5^2}[/tex]
[tex]=\sqrt{9+25}[/tex]
[tex]=\sqrt{34}[/tex] units
or
[tex]d = 5.8[/tex] units
Therefore, the distance between two points ( -1,1) and (2,-4) is:
[tex]d=\sqrt{34}[/tex] or d = 5.8 units.
A dripping tap wastes 11,250 ml of water in 9 hours. If it drips equal quantity in each hour ,how much water will be wasted in an hour? Express your answer in L.
Answer: In 1 hour , it will waste = 1.25ml
Step-by-step explanation:
Volume of water wasted by the tap in 9 Hours = 11,250 ml
Since it drips in equal quantity,
In 1 hr , it will drip= 1 x 11,250 / 9 = 1,250 ml
But 1000 ml = 1 Liter
1250 ml = 1250ml x 1Liter / 1000ml= 1.25L

What is the measure of the missing angle
The measure of the missing angle is 119 degrees.
Explanation:
This is because this angle is a supplementary angle, which means that two angles put together equal 180 degrees. Since we already know the measure of one angle (61 degrees), we can subtract it from 180 degrees. We could figure this out by doing 180-61, which would get us the measure of the missing angle, 119 degrees.
