Answer:
Equation: 5x = 90
x = 18
<LNM = 54degrees
Step-by-step explanation:
From the diagram shown;
<JNK + <KNL + <LNM = 90
x + x + 3x = 90
5x = 90
x = 90/5
x = 18
The equation 5x = 90 can be used to solve for x
Get <LNM = 3x
<LNM = 3(18)
<LNM = 54 degrees

which of the following correctly gives the center and radius of the circle defined by the equation (z-7)^2 = 10?
Hi there!
[tex]\large\boxed{\text{Center: (7,2); radius =} \sqrt{10}}}[/tex]
We know that the standard form of the graph of a circle is:
(x - h)² + (y - k)² = r²
Where:
h = x-coordinate of center
k = y-coordinate of center
r = radius
We can identify the following from the given equation:
(x - 7)² ⇒ h = 7
(y - 2)² ⇒ k = 2
r² = 10 ⇒ r = √10
Thus, the correct answer is C.
Answer:
its the third one C

2. ALMN and APMN are shown below. What additional information is necessary to prove
ALMN = APMN by HL?
Help please!!!
Answer:
The additional information necessary is option;
D. [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Step-by-step explanation:
From the given figure, we have;
Given that ML ≅ MP,
The Hypotenuse Leg HL theorem of congruency is used to prove that a given number of right triangles based on the lengths of their hypotenuse and one of the legs. It states that two or more right triangles are congruent if they have equal lengths of both their corresponding hypotenuse side and one leg
To prove that ΔLMN and ΔPMN are congruent by HL, we will also be required to prove that ΔLMN and ΔPMN are right triangles
For ΔLMN and ΔPMN to be right triangles, the angles, ∠LNM and ∠PNM should be right angles = 90°
With ∠LNM = ∠PNM = 90°, then, line [tex]\overline {MN}[/tex] is perpendicular to line [tex]\overline {LP}[/tex] or [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex]
Therefore, the additional information necessary to prove that ΔLMN ≅ ΔPMN by HL is [tex]\overline {MN}[/tex] ⊥ [tex]\overline {LP}[/tex].

The area of trapezium shaped field is 480 square meter, the distance between two parallel sides is 15m and one of the parallel side is 20m. Find the other parallel side
Answer: 44 m
Step-by-step explanation:
Given
The area of the trapezium is [tex]A=480\ m^2[/tex]
Distance between parallel sides [tex]h=15\ m[/tex]
One of the parallel sides is [tex]20\ m[/tex]
Suppose the other parallel side is [tex]x[/tex]
The area of the trapezium is
[tex]A=\dfrac{1}{2}\times [\text{Sum of parallel sides}]\times h[/tex]
Put values
[tex]\Rightarrow 480=\dfrac{1}{2}\times [20+x]\times 15\\\\\Rightarrow 480\times 2=300+15x\\\Rightarrow 960-300=15x\\\Rightarrow x=44\ m[/tex]

An environmentalist tracks the total number of trees y in a park after x years of a planting program. The line of best fit for the data is represented by the equation y = 3x + 15. What is the percent change in the total number of trees from x = 4 to x = 7? Round your answer to the nearest percent.
Answer:
33.33%
Step-by-step explanation:
The line of best fit for the data is represented by the equation y = 3x + 15.
At x = 4,
y = 3(4) + 15 = 27
At x = 7,
y = 3(7) + 15 = 36
We need to find the percent change in the total number of trees from x = 4 to x = 7.
So,
[tex]\%=\dfrac{36-27}{27}\times 100\\\\=33.33\%[/tex]
So, the required percentage change is equal to 33.33%.

What are the factors of the expression x^2+x-20?
Answer:
(x-4)(x+5)
Step-by-step explanation:
Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)
What is the value of x? Round to the nearest tenth.
Answer:
x=7.5
Step-by-step explanation:
first find the hypotenuse of the first right angles triangle a^2+b^2=c^2. 4^2+3^2=squareroot 25 (5)that 5 is the height of the second right angled triangle thus c^2-a^2=b^2. 9^2-5^2= 56 (squareroot is 7.48) round off 7.48 to the nearest tenth which is 7.5 since the hundredths value is more than 5hence answer is 7.5 Two highways meet at right angles in a town. Both highways are exactly straight
lines. Two cars leave the intersection at exactly the same time. One car starts traveling East
at 40mph and is decelerating at a rate of 1mph per hour. The other car starts traveling North
at 30mph and is accelerating at a rate of 0.5mph. At what rate is the distance between them
increasing 4 hours after they leave the intersection?
Answer:
Step-by-step explanation:
Using the relation :
S = ut + 1/2at²
S = distance
Car A :
Initial speed, u = 40 mph
a = negative acceleration = - 1 mph
At time, t = 4
S = 40(4) - 0.5(1)(4²)
S = 160 - 8
S = 152 miles
Car B :
Initial speed, u = 30 mph
a = acceleration = 0.5 mph
S = 30(4) - 0.5(1)(4²)
S = 120 - 8
S = 118 m
Change in distance / time
Rate of change = (152 - 118)m / 4 hours
Rate of change = 34 mi / 4 hr
Rate of change = 8.5 miles per hour

Answer:
$32.60
Step-by-step explanation:
Remember to find the percentage of something, times the number by the percentage, which is two decimals to the left. So 15% would be 0.15.
The total is unknown so replace it with a variable, such as x
.15(x)=4.89
Isolate x by dividing both sides by 0.15
x=32.6
Meal price: $32.60
Check your answer by multiplying this number by the tip percentages

ILL BRAINLIEST YOU IF YOU GET IT RIGHT! Please help me
Answer:
x = 25
Step-by-step explanation:
If JK and MN are parallel lines, then ∠JKL = ∠LMN = 61°
By the opposite angle rule, ∠JLK = 39°
In a triangle three angles sum up to 180°
so, ∠JLK + ∠JKL +LJK = 180°
39° + 61° + 3x+ 5 = 180°
3x = 75
x = 25
Step-by-step explanation:
[tex]61 + 39 + 3x + 5 = 180 \\ \\ 105 + 3x = 180 \\ \\ 3x = 180 - 105 \\ \\ 3x = 75 \\ \\ x = 75 \div 3 \\ \\ x = 25 \\ [/tex]
