What is the value of x/5
Answer:
2
Step-by-step explanation:
Since this is a right triangle we can use trig functions
cos theta = adj / hypotenuse
cos 60 = 5/x
.5 = 5/x
Flip each side
1 / .5 = x/5
2 = x/5
The ratio of angle measures is 1:2:2. Classify the triangle by its angle measures. obtuse triangle right triangle equiangular triangle acute triangle
Answer:
Acute Triangle
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
So, The lengths are:
=> 36
=> 72
=> 72
Since all the angles are less than 90 degrees, It is an acute triangle.
Answer: Acute Triangle hope this helps
As of mid-2016, the world's population was about 7.4 billion people. The population of the United States was 324 million.
The land area of a certain state is about 261,787 square miles. If in mid-2016 all of the world's people were put into that state, how many people would there be in each square mile? (Round your answer to the nearest whole number.)
Answer:
There would be approximately 28,267 per square mile.
Step-by-step explanation:
There are 7,400,000,000 people in the world. The state is 261,787 square miles.
7,400,000,000/261,787 = 28,267.2554 → 28,267

Work must be shown for this problem! The figure shown below is a rectangle. Make sure to solve for x and BD. Give both answers below.
Answer:
x = 10
BD = 74
Step-by-step explanation:
Find x by setting 3x+7 equal to 37. Solve for x by subtracting 7 on both sides then divide by 3 to get x=10.
Since 37 is half of AC, multiply that by 2 to find AC or BD, which are the exact same length of 74.
Answer:
x=10 and BD=74
Step-by-step explanation:
In a rectangle, the two parts of the diagonals are always equal to each other. This means that AE=CE=BE=ED.
So, if AE is 3x+7, this means DE and BE are also 3x+7, so BD is twice that, or 2(3x+7) which when you multiply it is 6x+14.
Oh, also, since it says CE=37, this means that 3x+7=37
3x+7=37
-7 -7
3x=30
x=10
Now that you know that BD is 6x+14, and x is 10, simply multiply it.
6(10)+14=BD
60+14=BD
74=BD

What is quotient and product rule of logarithm?Logarithm, the exponent or power to which a base must be raised to yield a given number. The quotient rule says that, the logarithm of a quotient is equal to a difference & the product rule says that logarithm of product is equal to the sum of logarithm.
Formula to be used,
log〖(ab)=loga+logb 〗
〖log(〗〖a/b)=loga-logb 〗
here, we have,
the given equation is,
㏑[tex]e^{ln( x)}[/tex] + ㏑[tex]e^{ln (x^{2}) }[/tex] = 2㏑8
or, ㏑x * ㏑ e + ㏑x² * ㏑e = 2㏑ 8
or, ㏑x + ㏑x² = 2㏑ 8
or, ㏑( x*x²) = ㏑ 8²
or, ㏑x³ = ㏑ 64
now, taking out the nature logarithm from both sides, we get,
x³ = 64
or, x = 4
Hence, The solution is, the true solution to the equation below is x=4.

Examine the following table that represents some points on a line.
Which equations in point-slope form represents this line?
y + 10 = 2(x + 6)
y + 9 = 1/2(x + 4)
y + 10 = 1/2(x + 6)
y + 4 = 1/2(x — 6)
y + 4 = 2 (x — 6)
y — 9 = 2(x — 4)
Answer:
Option (2), (3) and (4)
Step-by-step explanation:
Let the equation of the line representing the given table is,
y - y' = m(x - x')
where 'm' = slope of the line
(x', y') is the point lying on the line.
Let the two points (-6, -10) and (-4, -9) lie on the line
Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{-9+10}{-4+6}[/tex]
= [tex]\frac{1}{2}[/tex]
Equation of the line passing through (-4, -9) with slope [tex]\frac{1}{2}[/tex] will be
y - (-9) = [tex]\frac{1}{2}(x+4)[/tex]
y + 9 = [tex]\frac{1}{2}(x+4)[/tex]
Equation of the line passing through (-6, -10) with slope = [tex]\frac{1}{2}[/tex]
y - (-10) = [tex]\frac{1}{2}(x+6)[/tex]
y + 10 = [tex]\frac{1}{2}(x+6)[/tex]
Equation of the line passing through (6, -4) and slope = [tex]\frac{1}{2}[/tex]
y + 4 = [tex]\frac{1}{2}(x-6)[/tex]

A wooden toy kit has different painted solids. One solid is a cylinder with a diameter of 2cm and a height of 14cm.
Q.What is the surface area of the cylinder? (Answer is 96cm^2, I know how to get it)
Q.One can of paint covers 40m^2. How many cylinders can be painted with one coat of paint? (Answer is about 4244, but the question is how do you get it?)
Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders
which of the following equations is modeled by the graph.
a=5t
a=50t
a=50 + t
a=10t
Answer:
a = 50t
Step-by-step explanation:
The graph goes through (0,0) so the y intercept is 0
a=5t
a=50t
a=50 + t not it
a=10t
The slope is y/x since the y intercept is 0
m = 50/1 = 50
The equation for the line is
y = 50x+0
y = 50x
Using the variables given
