Answer:
x = 10
Step-by-step explanation:
First, distribute:
[tex]\frac{1}{5} x - \frac{2}{5} =\frac{1}{10} x+\frac{6}{10}[/tex]
Next, subtract [tex]\frac{1}{5}x[/tex] from both sides:
[tex]-\frac{2}{5} = \frac{1}{10} x -\frac{1}{5} x+\frac{6}{10}[/tex]
(multiply [tex]\frac{1}{5}x[/tex] by 2 to get common denominator, [tex]\frac{2}{10} x[/tex] )
[tex]-\frac{2}{5} =-\frac{1}{10}x +\frac{6}{10}[/tex]
Next, subtract [tex]\frac{6}{10}[/tex] from both sides:
[tex]-\frac{2}{5} -\frac{6}{10} =-\frac{1}{10} x[/tex]
(multiply [tex]\frac{2}{5}[/tex] by 2 to get common denominator, [tex]\frac{4}{10}[/tex] )
[tex]-\frac{10}{10} =-\frac{1}{10} x[/tex] ⇒ [tex]-1=-\frac{1}{10} x[/tex]
Next, multiply both sides by 10:
[tex]-10=-x[/tex]
FInally, divide both sides by -1:
x = 10
Answer:
Step-by-step explanation:
1/5(x-2) =1/10(x+6)
1/5x-2 = 1/10x+0.6
1/5x+1/10x= 0.6-2
0.2x+0.1x= -1.4
0.3x= -1.4
x= -4.67
x= -4.7
x= -5
The figure shows line RS parallel to line UV. The lines are intersected by 2 transversals.
If the measure of angle STV is 108 degrees and the measure of angle RST is 74 degrees, the measure of angle TVU is [blank1] degrees. :|
Answer:
Step-by-step explanation:
The measure of angle TVU is 74 degrees.
What is alternate interior angles?The alternate interior angles are the angles that are formed inside the two parallel lines, when it is intersected by a transversal, and are equal to its alternate pairs.
What is linear pair angles?Linear pair of angles are formed when two lines intersect each other at a single point.
According to the given question.
m ∠STV = 108 degrees
And,
m ∠RST = 74 degrees
Since, ∠RTS and ∠STV are linear pair of angles.
Therefore,
m ∠RTS + m ∠STV = 180
⇒ m ∠RTS + 108 = 180
⇒ m ∠RTS = 180 - 108
⇒ m ∠RTS = 72 degrees
Now, in ΔRTS we have
m ∠RTS + m ∠TSR + m ∠SRT = 180 (sum of the angles of a triangle is 180 degrees)
⇒ 72 + 74 + m ∠SRT = 180
⇒ m ∠SRT = 180 -146
⇒ m ∠SRT = 34 degrees
Here, ∠SRT and ∠TVU are alternate interior angles.
Therefore,
m ∠SRT = m ∠TVU
⇒ m ∠TVU = 74 degrees.
Hence, the measure of angle TVU is 74 degrees.

The length of a rectangle is 2x + 6. Its width is 52. Find the value of ac if the perimeter is 138m².
Answer:
ac = 18.5
Step-by-step explanation:
perimeter of a rectangle = [tex]2(l+b)[/tex]
= 138m^2= 2(2x + 6 ) + 52
= 4x + 12 + 52 = 138
= 4x + 64 = 138
= 4x = 138 - 64
= 4x = 74
= x = 74/4
= x = 18.5

Answer:
x=[tex]\sqrt{2}[/tex]/4 and x=-[tex]\sqrt{2}[/tex]/4
Step-by-step explanation:
One method of solving is using the Quadratic Formula: -b ±[tex]\sqrt{b^{2}-4ac }[/tex]/2a, with a=8, b=0, and c=-1.
After plugging these values in you get -0±[tex]\sqrt{0^2-(4*8*-1)}[/tex]/2*8
After simplifying you get ±[tex]\sqrt{32}[/tex]/16
Because 32 is 2^5, you can simplify it to 4[tex]\sqrt{2}[/tex], which makes the equation ±4[tex]\sqrt{2}[/tex]/16, or ±[tex]\sqrt{2}[/tex]/4.

The graph of f(x) is translated 5 units down to create the graph of g(x).
The graph of g(x) is translated 2 units up and is steeper than the graph of f(x).
Answer:
ME TOO
Step-by-step explanation:
Function transformation involves changing the position of a function.
The relationship between f(x) and g(x) is (d) The graph of g(x) is translated 2 units up and is steeper than the graph of f(x).
The functions are given as:
[tex]\mathbf{f(x) = x}[/tex]
[tex]\mathbf{g(x) = -5f(x) + 2}[/tex]
Substitute x for f(x) in g(x)
[tex]\mathbf{g(x) = -5x + 2}[/tex]
The +2 in [tex]\mathbf{g(x) = -5x + 2}[/tex] means that, g(x) is gotten by translating f(x) up by 2 units.
The -5 in [tex]\mathbf{g(x) = -5x + 2}[/tex] means that, g(x) has a steeper slope.
Hence, the correct option is (d)

Answer:
The next term is 64, a is 2, and the common ratio is 2.
Step-by-step explanation:
Look at what's happening from each number to the next. What do you need to do to get from 2 to 4, or 4 to 8? Multiply by 2. That's your common ratio. To get the next number in the sequence, multiply the last number by the common ratio of 2. 32 x 2 = 64, so the next number in the sequence is 64. "a" is just the very first term, meaning it's 2.

The width of a rectangle measures (26 – 8c) centimeters, and its length measures
(106 + 6c) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answer:
first one is correct
Step-by-step explanation:
length of a rectangle = 2b - 8c
breadth of a rectangle = 10b + 6c
now , formula to calculate the perimeter of rectangle is
p = 2 (l + w)
no substitute the value of l(length) and w(width)
p = 2{(2b - 8c) + (10b + 6c)}
p = 2(2b - 8c + 10b + 6c)
p = 2(12b - 2c)
p = 24b - 4c

by 20% the second year.
a) Find the population after the second

b) Explain why there was not a 30%
increase in population over the two years.
Answer:
The population would probably be 40%
Step-by-step explanation:
10 x 2 = 20
20 x 2 = 40
So, instead of increasing by 10% every year, the population from the previous year just doubles. Sorry if I'm wrong!

Since you are trying to figure out how many gumballs you need to fill a 7.3 x 5.0 x 9.4 rectangular box for Halloween, and each gumball has a radius of 1/2 in, if the packing density for spheres is 5/8 of the volume will be filled with gumballs while the rest will be air how many gumballs will be needed, to determine this amount the following calculation must be performed:
(Volume of box x 5/8) / volume of gumballs = Amount of gumballs Volume of a sphere = 4/3 x 3.14 x (radius x radius x radius) Volume of a gumball = 4/3 x 3.14 x (0.5 x 0.5 x 0.5) = 0.5235 inches ((7.3 x 5 x 9.4) x 5/8) / 0.523 = X (343.1 x 5/8) / 0.523 = X 214.4375 / 0.523 = X 410 = XTherefore, 410 gumballs will be needed to fill the box.
