length of the other diagonal.
Answer: The length of the other diagonal is 8 cm.
Step-by-step explanation:
Area of rhombus = [tex]\frac{pq}{2}[/tex]
[tex]\frac{4q}{2} =16\\[/tex]
[tex]4q = 32\\q = 8\\[/tex]

Answer:
C. 2(6)-2x=3
Step-by-step explanation:
You distribute the 2 to the 6 and then to the negative x
For what values of r will the area of
the shaded region be greater than or equal to
12 square units?
3х – 6 = 4 (2 - 3х) — 8x
what is x?
Answer:
x = 2/5 or 0.4
Step-by-step explanation:
3x - 6 = 4(2 - 3x) - 8x
distribute
3x - 6 = 4*2 - 4*3x - 8
3x - 6 = 8 - 12x - 8
combine like terms
3x - 6 = -12x
add 12x to both sides of the equation
3x - 6 + 12x = -12x + 12x
3x - 6 + 12x = 0
15x - 6 = 0
add 6 to both sides of the equation
15x - 6 + 6 = 0 + 6
15x = 6
divide both sides of the equation by 15
15x/15 = 6/15
x = 6/15
x = 2/5
x = 0.4

what is 150 % of 32 ?
i already know that it’s 48, i just really need to know how “i” got it.
Answer: 48
=================================================
Explanation:
The keyword "of" means multiply
150% converts to the decimal form 1.5; you move the decimal point two spots to the left to go from percent form to decimal form
Putting those two facts together lead to...
150% of 32 = 1.5*32 = 48
----------------
Another approach:
x% = x/100
150% = 150/100 = 1.5
150% of 32 = 1.5*32 = 48
The last step is identical as before, but the conversion of 150% is slightly different this time.
------------------
Yet another approach:
100% of anything is itself
So 100% of 32 is 32
The extra 50% means we take half of 32 to get 16. Then we add that onto the 32 to get 16+32 = 48

I would say A because 6:3 can only equal 1/3.
Step-by-step explanation:
It would help if you formatted a bit better though. As the choices are not clear. ^^
The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3
Since, The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
Here, We have;
There are 48 possible outcomes in this situation, and of those outcomes, the ones whose sums are a multiple of three are;
12, 21, 15, 51, 24, 42, 33, 18, 27, 36, 63, 45, 54, 48, 57, and 66.
So, that is 16 out of 48 possibilities,
⇒ 16/48,
⇒ 1/3.
Thus, The probability of getting numbers whose sum is a multiple of three is,
⇒ 1 / 3

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.
We have [y] varies directly with [x] and y doubles then x.
The general equation of a straight line can also be used to represent proportional relationship when [c] = 0.
y = mx + c
y = mx + 0
y = mx
m = y/x
where [m] is constant of proportionality.
A/C to question -
y = 2x
Here, the constant of proportionality is 2.
Therefore, the constant of proportionality is 2.

Answer:
a) BE = 5; DE = 6; EF = 4
b) ∠EFC ≅ ∠DA.F ≅ ∠BDE or b = e = f = i
Step-by-step explanation:
Each short segment is the same length as the marked one it is parallel to.
E is the midpoint of BC, so BE = EC = 5.
ADEF is a parallelogram, so DE = A.F = 6.
D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...
EF = AD = 4
__
As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. b = e = f = i

v = 21
Step-by-step explanation:
the sum of the interior angles of a triangle is 180 degrees
add all 3 angle measures and set equal to 180:
4v + 2v + 54 = 180
6v = 126
v = 21
I need the answer and how to solve this
Answer:
50
Step-by-step explanation:
Since 140° is on the outside, the angle next to it would be 40°.
Also a triangle = 180°
40° + 90° = 130°
180° - 130° = 50°
Thus meaning x = 50°
Answer:
x = 50°
Step-by-step explanation:
- the angle at the top is shown as a right angle so it is 90°
-the 140° angle and the angle next to it are 180° together so let's name the other angle z
z+140=180
z=180-140=40°
- a triangle's angles in total have 180°
x+y+z= 180°
x+90°+40°=180°
x+130 =180
x= 180-130 = 50°
