Answer:
-1/12
Step-by-step explanation:
3/6 + (-5/6) = -2/6
-2/6 = -4/12
1/4 = 3/12
-4/12 + 3/12 = -1/12

HELPPP!! Find the missing angles in the following RHOMBUS. *
please enter: 1: _____, 3: _____, 4: ________
Answer:
3= 32 4=90 1=58
Step-by-step explanation:
Answer:
<1=58°
<3=32°
<4=90°
Step-by-step explanation:
<1=58° (180-90-32)
<3=32° (Same a the angle across from it because it’s an isosceles triangle)
<4=90°
This Rhomus is definitely not drawn correctly, so the image is deceptive. For example, two 32° angles would not make an obtuse angle. You just have to ignore the picture and do the Math.

35. Para pintar una casa se mezclaron 5/4 L do pintura blanca y 1/2 L de pintura azul. Al final solo se emplearon 213 L de la mezda,
¿cuántos litros de pintura sobraron?
Answer:
Total paint left over = [tex]\frac{13}{12}L[/tex]
Step-by-step explanation:
Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint
were mixed. In the end only 2/3 L of the mixture were used.
To find - How many liters of paint were left over ?
Proof -
Given that,
5/4 L of white paint and 1/2 L of blue paint were mixed.
So, total mixture = [tex](\frac{5}{4} + \frac{1}{2})L[/tex]
= [tex]\frac{5 + 2}{4}L[/tex]
= [tex]\frac{7}{4}L[/tex]
⇒Total mixture = [tex]\frac{7}{4}L[/tex]
Now,
Given that ,
In the end only 2/3 L of the mixture were used.
So, total mixture left = [tex](\frac{7}{4} - \frac{2}{3})L[/tex]
= [tex]\frac{21 - 8}{12}L[/tex]
= [tex]\frac{13}{12}L[/tex]
∴ we get
Total paint left over = [tex]\frac{13}{12}L[/tex]
Find the radius of a circle with a circumference of 23.55 feet. Use 3.14 for
Answer:
3.75
Step-by-step explanation:
The radius of the circle will be (11.775/π).
What is the area of a circle? What is an exponential function? Differentiate between equation and expression? area of circle : The area of a circle is equivalent to -[A] = πr² = πd²/4
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the circumferance of the circle is 23.55 feet.
We can write -
2πr = 23.55
r = (23.55/2π)
So, the area of the circle will be -
{A} = πr²
{A} = π x (23.55 x 23.55)/4π²
{A} = (555/4π)
{A} = 138.75/π
r = (23.55/2π)
r = (11.775/π)
Therefore, the radius of the circle will be (11.775/π).

What is the measure of the angle of the hands on a clock if it is 3:24?
Answer:
from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.
Answer:
42deg
Step-by-step explanation:
Let's see.
We'll consider 12:00 the "starting position"
The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.
The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.
at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg
The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.

Tell weather the angles are complementary or supplementary. The. Find the value of x. WITH EXPLANATION
Decide if the expression is positive or negative. Explain in words how you know, please.
-11 x (2/3) and -11 x (-2/3)
Step-by-step explanation:
The first expression is :
[tex]-11\times \dfrac{2}{3}[/tex]
Numerator = -11×2 = -22
Denominator = 3
So, answer will be :
[tex]-11\times \dfrac{2}{3}=\dfrac{-22}{3}[/tex] (negative)
The second expression is:
[tex]-11\times \dfrac{-2}{3}[/tex]
Numerator = -11×-2 = 22
Denominator = 3
So, the answer will be :
[tex]-11\times \dfrac{-2}{3}=\dfrac{22}{3}[/tex] (positive)
Hence, this is the required solution.
Explain how I got 100(x + 7 y from 100x + 700y
Help me with this please. thanks.
Answer:
Step-by-step explanation:
It's linear.
First of all, let's recreate the table.
The equa ttion is something like
y = a x
Now if x = - 9
and y = - 157 / 3
Then a = -157/ (-9*3)
a = 5.814814814....
y = 5.814814 (-8)
y = - 46.5185185....
y = -139/3 = -46.333333333 the difference is in how this was rounded.
y = 5.814814 * -7 = 40.703703703...
y = -121/3 = -40.333333 Again another rounding problem.

Help please thank you
Answer:
A, B and D are true.
Step-by-step explanation:
g (x) = x² - 4x + 3
f (x) = x² - 4x
What this means is that;
g (x) = f (x) + 3
What this implies is that the graph of g (x) is equivalent to when we shift that of f function graph up by 3 units.
Since g (x) is essentially shifting of f (x) upwards by 3 units, it means the graphs will never intersect.
It also implies that the vertex of g (x) will be above that of f (x)
Also since it only moves up and not in any other direction, both functions will still have the same line of symmetry.
Thus, options A, B and D are correct
