MK = 24, JL = 20, and m
The quadrilateral below is a rhombus. Find the missing measures. Any decimal answers should be rounded to the nearest tenth.
NK =
m
NL =
m
ML =
m
JM =
m
m
Answer:
The answer is below
Step-by-step explanation:
If the quadrilateral below is a rhombus, find the missing measures.
MK = 24, JL = 20, and mZMJL = 50°
Solution:
A rhombus is a quadrilateral (has four sides and four angles) such that all the sides are of equal length.
The diagonals of a rhombus bisect each other.
NK = MK / 2 (diagonals of a rhombus bisect each other)
NK = 24 / 2 = 12
NL = JL / 2 (diagonals of a rhombus bisect each other)
NL = 20 / 2 = 10
In triangle MNL, ∠N = 90°
MN = NK = 12 , NL = 10. Using Pythagorean theorem:
ML² = MN² + NL²
ML² = 12² + 10²
ML² = 244
ML = √244
ML = 2√61 = 15.62
JM = ML = 15.62 (all sides of a rhombus are equal)
∠KNL = 90° (diagonals are perpendicular bisectors)
∠KJL = ∠MJL (diagonals bisect angles)
∠KJL = 50°
∠MJK = ∠KJL + ∠MJL = 50 + 50 = 100°
∠MJK = ∠MLK (opposite angles are equal)
∠MLK = 100°
∠NJK + ∠JNK + ∠JKM = 180° (sum of angles in triangle)
50 + 90 + ∠JKM = 180
∠JKM = 40°
∠JKL = 2 * ∠JKM (diagonal bisect angle)
∠JKL = 2 * 40
∠JKL = 80°
∠JKL = ∠JML (opposite angles are equal)
∠JML = 80°

The length of a rectangle is eight more than twice it's width. the perimeter is 96 feet. find the dimensions
Variables:
equation:
Solution:
Answer:
the length and width be 13.33 feet and 34.67 feet respectively
Step-by-step explanation:
The computation is shown below:
Let us assume the width be x
So, the length be 2x + 8
As we know that
The perimeter of the rectangle = 2(length + width)
96 = 2(2x + 8 + x)
96 = 4x + 16 + 2x
96 - 16 = 6x
80 = 6x
x = 80 ÷ 6
= 13.33 feet
So, the length would be
= 2 × 13.33 + 8
= 34.67 feet
Hence, the length and width be 13.33 feet and 34.67 feet respectively

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?
Answer:
96 seconds
Step-by-step explanation:
In order to find how long it will take to empty the bucket, you must multiply the number of gallons by the reciprocal of the fraction.
1. Reciprocal of [tex]\frac{1}{3}[/tex] is [tex]\frac{3}{1}[/tex] which is 3
2. multiply 32 by 3 to get your answer, 96.

The ratio of males to females at a party is 3 : 5
There are 12 more females than males.
How many people are at the party?
Answer:
48
Step-by-step explanation:
Given ratio of males to females at a party is 3 : 5.
Let the numbers of males and females be 3x and 5x respectively.
According to the given description:
No of females = No of males + 13
Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
No of people at the party
= 3x + 5x
= 8x
= 8*6
= 48

One side of a rectangle is 3 inches shorter than the other side, and the perimeter is 54 inches. What are the dimensions of the rectangle?
Which of the following equations could be used to solve the problem?
A. 2 x + 2( x - 3) = 54
B. 2 x - 3 = 54
C. 2 x + 2 x - 3 = 54
Answer:
A
Step-by-step explanation:
Let the two sides of the rectangle be x and y.
Then the perimeter will be:
[tex]2x+2y=P[/tex]
Since the perimeter is 54:
[tex]2x+2y=54[/tex]
We know that one side of the rectangle is 3 inches shorter than the other.
Let y be the shorter side. It is 3 less than x.
Therefore:
[tex]y=x-3[/tex]
Then by substitution, we acquire:
[tex]2x+2(x-3)=54[/tex]
The answer is A.
16q3-48q2+32q what would be the steps on how to do this? please?
Answer:
Its nothing complicated, you just have to combine all the like terms, just make sure the lvariables are the same before combining of course.
so assuming the gaps missng are exponents
the solution is the same exact thing
it can’t be simplified anymore since 16q^3 or -48q^2 can’t due to different exponents which thefore can’t combine
same with 32 q, nothing combines
The answer is the original expression
For what values of x and y are the triangles to
the right congruent by HL?
Answer:
x = 12, y = 4
Step-by-step explanation:
For the triangles to be congruent by HL , then
x = y + 8 → (1)
4y = x + 4 → (2)
Substitute x = y + 8 into (2)
4y = y + 8 + 4
4y = y + 12 ( subtract y from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Substitute y = 4 into (1)
x = 4 + 8 = 12

5.3x + y = 28.5
4.2x + 3.1y = 27.2
find x and y
Answer:
x = 5, y = 2
Step-by-step explanation:
First, isolate y in the top equation.
[tex]y = -5.3x+28.5[/tex]
Next, substitute y in the bottom equation.
[tex]4.2x + 3.1(-5.3x + 28.5) = 27.2[/tex]
[tex]5.3x + y = 28.5[/tex]
Simplify.
[tex]4.2x + -16.43x + 88.35 = 27.2[/tex]
Combine like terms.
[tex]-12.23x + 88.35 = 27.2[/tex]
Isolate x on one side.
[tex]-12.23x = -61.15[/tex]
Isolate x.
[tex]x = 5[/tex]
Substitute x into [tex]5.3x + y = 28.5[/tex]
[tex]5.3(5) + y = 28.5[/tex]
Simplify.
[tex]26.5 + y = 28.5[/tex]
Isolate y.
[tex]y = 2[/tex]
[tex]x = 5 \\y = 2[/tex]
how do you convert x + 5y =-5 into slope intercept form?
Answer:Convert it to the slope intercept form by solving for y . Add x to both sides. Divide both sides by 5 . y=15x−1 is the slope intercept form of a linear equation, y=mx+b , where m is the slope, 15 and b is the y-intercept, −1

A video posted to the internet had 3,200 views in its first week
(a ) The video got 4, 640 views in its second week. What was the percent increase in the views from the first week?
Answer:
45%
Step-by-step explanation:
The computation of the percentage increase from the first week is shown below:
Given that
In the first week there is 3,200 views
And, in the second week, there is 4,640 views
So, the percentage increase is
= (Second week views - first week views) ÷ (first week views)
= (4,640 - 3,200) ÷ (3,200)
= 45%

A running track has two straight sides with length 140 m and two semicircle ends with radius 70 m. It takes Kat 40 seconds to jog 160 m. How long would it take her to jog around the track 51 times? Give your answer in hours and minutes, to the nearest minute.
It would take her 4590 seconds to jog round the track 51 times
Speed is the ratio of the total distance travelled to total time taken. It is given by:
Speed = distance / time
Kat uses 40 seconds to jog 160 m, hence:
Speed = 160 m / 40 s = 4 m/s
The track length = 140 m + 2 * (π * 70) = 360 m
Time taken to jog round the track (t) is:
4 m/s = 360 m / t
t = 90 s
To jog round the track 51 times, time taken = 51 * 90 s = 4590 seconds
It would take her 4590 seconds to jog round the track 51 times
