Answer:
x is 30° and y is 20°.
Step-by-step explanation:
In an equilateral triangle all the angles form 60°.
1) 2x = 60
x = 60/2
x = 30°.
2) 3y = 60
y = 60/3
y = 20°.
x is 30° and y is 20°.
Answer:
y=20
x=30
Step-by-step explanation:
All the angles in an equilateral triangle is equal to 60 degrees. Knowing this, we can set up the following equations:
3y=60
2x=60
3y=60
Divide both sides by 3
3y/3=60/3
y=20
2x=60
Divide both sides by 2
2x/2=60/2
x=30

Slope 7; (4,-30 equation
Answer: y=7x-68
Step-by-step explanation: Ok so you would use point slope to slope so plug the points in. y+30=7(x-4) then if you need to convert it further into slope intercept form just simplify and distribute. So y+30=7x-28, subract 30 from both sides to get y=7x-68
Hence, the slope of line is [tex]y=7x-58[/tex].
What is the slope of line?
The slope of a line gives the measure of its steepness and direction. The slope of a straight line between two points says [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be easily determined by finding the difference between the coordinates of the points.
The slope is usually represented by the letter ‘m’.
Here given that,
Slope is [tex]7[/tex] and the coordinates of [tex](x,y)=(4,-30)[/tex].
As we know slope of line is
[tex]y=mx+c[/tex]
where [tex]m[/tex] is the slope.
So,
[tex]y+30=7(x-4)[/tex]
Now convert it further into slope intercept form
[tex]y+30=7x-28\\\\y=7x-28-30\\\\y=7x-58[/tex]
Hence, the slope of line is [tex]y=7x-58[/tex].

A straight angle is broken into 3 angles. The first angle measures 38°, the second angle is a right angle. What is the measurement of the 3rd angle?
Answer: The measurement of the 3\large ^{rd} angle is
Answer:
52°
Step-by-step explanation:
Let the measure of the third angle be x°.
Since, straight line is broken into three angles. So, the sum of all the three angles will be equal to 180°.
38° + 90° + x = 180°
128° + x = 180°
x = 180° - 128°
x = 52°
Answer:
52°
Step-by-step explanation:
So, we basically know that,
A straight Angle=180°
When it has been broken into 3 pieces, we have gotten one which is 38°and a right angle.
Now , we know that
A right angle= 90°
So, we need to do,
Sum of known angles= 38+90=128°
Lastly,
Unknown angle = 180° - 128° = 52°

What's ƒ(g(4)) if ƒ(x) = 3x2 – 3x + 6 and g(x) = 2x?
Answer:
Step-by-step explanation:
In order to do f(g(4)), we need to find what g(4) is in order to input it into the function f(x).
g(4) = 2(4) = 8
Now do f(8) because that's the value of g(4)
f(8) = 3(8^2) - 3(8) + 6 = 174

Answer:
All of the above.
Step-by-step explanation:
By looking at the graph and taking point x at 4 and y at around 300. This shows us the precise rate of the graph which is when x = 4, y is equal to 300.
Now if we substitute the x as 4 in any of the equations we will get values larger than 300. Therefore, all the equations have a greater rate of change.
y = 85(4) = 340 (Greater)
y = 50(4) + 150 = 350 (Greater)
y = 65(4) + 100 = 360 (Greater)

Answer:
- True
- True
- False
- True
Step-by-step explanation:
- Subtracting the equation will get rid of y variable therefore it's a correct and logical first step to solve the system
- The solution is indeed (-3, -3) as if we substitute these values in both equation, the equation will be correct and valid.
[tex]-2(-3)+(-3)=3[/tex] (Correct)
[tex]3(-3)+2(-3)=-15[/tex] (Correct)
- We have already determined the logical first step. Multiply by -2 will not get rid of any of the variables. Therefore, this is false.
- The solution can be written as one value since x = y = -3. Therefore, this statement is true.

Answer:
A sampling distribution of the sample proportion with n = 20 and p = 0.8
Step-by-step explanation:
We are given that
The probability of tails of a weighted coin, p=0.8
n=20
We have to find the type of distribution is simulated if this procedure repeated 75 times .
Random variable is a proportion of number of tails therefore, type of distribution is sampling distribution of the sample proportion.
We have n=20 and p=0.8
Hence, we can say that type of distribution is simulated is given by
A sampling distribution of the sample proportion with n = 20 and p = 0.8

If the perimeter of a square is 5 feet now many Inches long is each side of the square
Answer:
The perimeter is 60 inches in total, and 15 for each side.
Step-by-step explanation:
The perimeter of a square is four times the length of one of its sides. So you divide 5 by 4 to get the length of each individual side.
5feet /4 sides = 1.25 feet
So each side is 15 inches long.

A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
Answer:
Kitten is 15 seconds and dog is 10 seconds
In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time.The kitten eats a sausage in 15 seconds and puppy eats a sausage in 10 seconds.
What is concept of Work and time?
In work and time the time taken is inversely proportional to the work done. Work and time is a concept to solve the problems of work related question in a given time
Given-Puppy and kitten eats one sausage combined in 6 sec.
A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage.
Let puppy eats a sausage in [tex]x[/tex] seconds and kitten eats a sausage in [tex]y[/tex] seconds.
As Puppy and kitten eats one sausage combined in 6 sec.Thus,
[tex]\dfrac{1}{x} +\dfrac{1}{y} =\dfrac{1}{6}[/tex]
Let above equation is equation one.
A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. Thus
[tex]\dfrac{1}{x} -\dfrac{1}{y}=\dfrac{1}{5}[/tex]
Put this value of [tex]x[/tex] in the the equation one to get the value of y. Therefore,
[tex]\dfrac{1}{6} -\dfrac{1}{y}-\dfrac{1}{y}=\dfrac{1}{5}[/tex]
[tex]-\dfrac{1}{2y}=\dfrac{1}{5}-\dfrac{1}{6}[/tex]
[tex]-\dfrac{1}{2y}=-\dfrac{1}{30}[/tex]
[tex]y=15[/tex]
Thus the kitten eats a sausage in 15 seconds.
Put the value of y in equation one. thus,
[tex]\dfrac{1}{x} +\dfrac{1}{15} =\dfrac{1}{6}[/tex]
[tex]\dfrac{1}{x} =\dfrac{1}{6}-\dfrac{1}{15}[/tex]
[tex]\dfrac{1}{x} =\dfrac{9}{90}[/tex]
[tex]x=10[/tex]
Thus the puppy eats a sausage in 10 seconds.
Hence the kitten eats a sausage in 15 seconds and puppy eats a sausage in 10 seconds.
