find the value of x easy math question #3 please help
Answer: x =8
Step-by-step explanation:
-12 + 9x = 60 (the other angles are 60, 180 - (60 + 60) = 60)
9x = 72
x = 8
Answer:
x = 8°
Step-by-step explanation:
We know that sum of interior angles of a triangle is 180°, therefore;
(Angle 1) + (Angle 2) + (Angle 3) = 180°
(60)° + (60)° + (-12 + 9x)° = 180°
120° + (-12 + 9x) = 180°
108° + 9x° = 180°
9x = 180 - 108
9x = 72°
x = 72/9
x = 8°
Therefore the value of x is 8°.

The value of a company's equipment is $33,000 and decreases at a rate of 12% each year. Write an exponential decay function for the value of the equipment after
tyears
Of(t) = .88t + 33000
Of(t) = 33000(88)
Of(t) = 0.88(33000)
Of(t) = 33000(12)

In which geometry is there more than one line parallel to a given line through a point not on the line?
A. spherical
B. Hyperbolic
C. Euclidean
D.apennine
Answer:
Step-by-step explanation:Its B because Hyperbolic geometry, also called Lobachevskian Geometry, a non-Euclidean geometry that rejects the validity of Euclid's fifth, the “parallel,” postulate. Simply stated, this Euclidean postulate is: through a point not on a given line there is exactly one line parallel to the given line.

Is the second plus third greater than the first ? is 4+1 >3?___________
Is the third plus first greater than the second? Is 3+1 >4_________
Can it make a triangle? Explain why?
9514 1404 393
Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is not satisfied.
_____
Additional comment
You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.
To the nearest square inch, what is the surface area of the cone?
The image consists of an inverted three-dimensional cone. The diameter of its circular base is 3 inches. The diagonal length from the base to the tip is 4 inches.
Answer: [tex]\frac{363}{14} [/tex] square inches
Step-by-step explanation:
Surface area of cone = [tex]\pi r( l +r)[/tex], where r= radius of the base of cone, l= diagonal length from the base to the tip
As per given,
Diameter = 3 inches
radius(r) = [tex]\frac32[/tex] inches
l = 4 inches
Surface area = [tex]\frac{22}{7} (\frac32)(4+\frac32)[/tex]
= [tex]\frac{22}{7} (\frac32)(\frac{11}2)[/tex]
= [tex]\frac{363}{14} [/tex] square inches
Required surface area of cone = [tex]\frac{363}{14} [/tex] square inches
I would appreciate if someone could answer this :)
Answer:
x = 3
Step-by-step explanation:
(-2 + 40x) + 62° = 180° (adjacent angles are supplementary)
-2 + 40x + 62 = 180
Add like terms
40x + 60 = 180
Subtract 60 from each side
40x + 60 - 60 = 180 - 60
40x = 120
Divide both sides by 40
40x/40 = 120/40
x = 3
Methods of statistics show that if a vegetarian diet had no effect on blood pressure, there would be less than 1 chance in 100 of getting these results. Does the result have statistical significance? Why or why not? Does the result have practical significance?
Answer: hi your question is incomplete below is the complete question
answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
A 10 meter ladder was placed on an angle. The base of the ladder is 5 meters away from the
building along the ground.
Write an equation to determine the height, h, of the building.
Answer:
5^2 + h^2 = 10^2
Step-by-step explanation:
This is a clear example of the Pythagorean Theorem, a relation of all sides in a right triangle. The equation itself is a^2 + b^2 = c^2. By simply plugging in the given values into the triangle, you would get the answer.
Answer:
To determine the height we will use a² = b²+c²
(10m)²= (5m)²+(h)²
<=> 100m²=25m²+h²
<=> 100m²-25m²=75m²=h²
<=> √ 75m² = h = 8,660m

Answer:
6
Step-by-step explanation:
We need to find the slope
We have 2 points
(0,0) and (1,6)
m = (y2-y1)/(x2-x1)
= (6-0)/(1-0)
= 6/1
= 6
y = 6x
The constant of proportionality is 6
Answer:
The constant of proportionality is 6.
Step-by-step explanation:
(0,0) and (1,6)
m = (y2-y1)/(x2-x1)
→ (6-0)/(1-0)
→ 6/1
So, y = 6x.
how do i solve 2/7v-1/7+14=20
Answer: 1: Combine multiplied terms into a single fraction
2: Multiply the numbers
3: Add the numbers
4: Solution
= 43/2
Step-by-step explanation:
Answer:
v = 43/2.
Step-by-step explanation:
2/7v - 1/7 + 14 = 20
2/7 v = 20 - 14 + 1/7
2/7 v = 6 1/7
2/7 v = 43/7
v = 43/7 / 2/7
v = 43/7 * 7/2
v = 43/2

In a sample of 234 individuals over the age of 25, chosen at random from the state of Oregon, 48 did not have a high school diploma. What is the upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma
Answer:
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
In a sample of 234 individuals over the age of 25, chosen at random from the state of Oregon, 48 did not have a high school diploma.
This means that [tex]n = 234, \pi = \frac{48}{234} = 0.2051[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.2051 + 1.96\sqrt{\frac{0.2051*0.7949}{234}} = 0.2568[/tex]
The upper bound of a 95% confidence interval for the proportion of individuals over the age of 25 in Oregon who do not have a high school diploma is of 0.2568.

F(x) = -3x-3 g(x) =2x^3+2
Find f(6) and g(-3)
Answer:
[tex]f(6)=-21\\\\g(-3)=-52[/tex]
Step-by-step explanation:
When given the following two functions,
[tex]f(x) =-3x-3\\g(x)=2x^3+2[/tex]
One is asked to evaluate the functions for, (f(6)) and (g(-3)). One can do this by substituting the values (6) into the function (f) and (-3) into the function (g). These values will replace the parameter (x).
[tex]f(6)=-3(6)-3\\[/tex]
Simplify,
[tex]f(6)=-18-3\\f(6)=-21[/tex]
Now repeat this process for the guncion (g(x)) to evaluate for (g(-3))
[tex]g(-3)=2(-3)^3+2[/tex]
Simplify,
[tex]g(-3)=2(-27)+2\\g(-3)=-54+2\\g(-3)=-52[/tex]

Which statement best describes Jim's first error
Write an equation of a line that passes through the point (2,6) and is parallel to the line y = -3
Answer:
y=6
Step-by-step explanation:
Let us start with the general equation of a line, y=mx+b. m represents the slope of the line, b represents the y intercept, and the y and x represents the values of the coordinate that the line passes through.
In this case, we know our line is parallel to y=-3, thus it has the same slope as it. Notice that in y=-3, there is no x. Therefore, the slope must be 0!
We now have equation:
[tex]y=0x+b[/tex]
Let us plug in the coordinate it passes through (2,6), to solve for b.
[tex]6=0*2+b\\6=b\\[/tex]
Now we have everything! Let us write the equation of the line now.
[tex]y=6[/tex]
I hope this helps! Let me know if you have any questions :)
