Answer:
[tex]x=7,\\m\angle LKN = 84^{\circ}[/tex]
Step-by-step explanation:
1. For KM to be the angle bisector of angle LKN, it must be bisect LKN into two equal angles. Therefore, we have the following equation:
[tex]9x-21=6x,\\-21=-3x,\\x=\boxed{7}[/tex]
2. Substituting [tex]x=7[/tex]:
[tex]\angle LKN=9x-21+6x=9(7)-21+6(7)=63-21+42=\boxed{84^{\circ}}[/tex]

Find the surface area and volume of the prisim it has 5cm 12cm 13cm and 28cm The surface area of the prism is (blank)cm2 The volume of the prism is (blank)cm3 pls help i need this quick!
Answer:
A = 1124 cm²
V = 840 cm³
Step-by-step explanation:
Assuming the prism is a triangular prism,
Applying,
V = 1/2bhL.................. Equation 1
Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle
From the question,
Given: L = 28 cm, 12 cm, h = 5 cm
Substitute these values into equation 1
V = (5×12×28)/2
V = 840 cm³
Surface area (A) = bh+(a+b+c)L
A = (5×12)+(13+13+12)28
A = 60+1064
A = 1124 cm²
(2/5)^-2(-3)^4
What is the equivalent?
Answer:
-8100
Step-by-step explanation:
(2/5)^-2(-3)^4
Given data
and second term
The first term= (2/5)^-2 and
Second term=(-3)^4
Simplify the first term
(2/5)^-2= 2^-2/ 5^-2= 1/2^2 * 1/5^2
=1/4/ 1/25
=1/4*25/1
=100
Simplify the second term
=(-3)^4
= -81
Hence, 100*81
=-8100
please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
71
Step-by-step explanation:
Recall the trig ratios
Sine = Opposite over Hypotenuse
Cosine = Adjacent over Hypotenuse
Tangent = Opposite over Adjacent
We are given ∠T's opposite side length and the adjacent side length.
When dealing with opposite and adjacent we use trig ratio Tangent.
( remember tan = opposite over adjacent )
[tex]tan(x)=\frac{52}{18}[/tex]
* multiply each side by the inverse of tan ( [tex]tan^-^1[/tex] )
[tex](tan)^-^1tan(x)=x\\(tan)^-^1*\frac{52}{18} =70.906508\\x = 70.906508[/tex]
* round to the nearest degree *
We get that x = 71

a had 8 b had 10 total=180
Step-by-step explanation:
it's weird. I never really liked word problems but think through it. if each of them had to be the same amount of points, then what does bothe 10 AND 8 fit into?
80. simple.
so that means there were 8 true false questions in section a and 10 multiple choice in b and there was 160 points total because 80 +80 = 160

Assume a class has 25 students.
a) If 80% of the class passed the test, how many students passed?
students
b) If 7 students got A’s on the test, what percent of students got A’s?
%
Answer:
A) 20
B) 28%
Step-by-step explanation:
A) In order to find percentages you need to make them in to decimals. 80% as a decimal is .8, if you multiply 25 by the decimal .8, you get 20.
B) To find the percentage all you do is divide, 7/25, this gives you the decimal .28, this as a percentage is 28%.

A rectangle is placed around a semicircle as shown below. The length of the rectangle is 14 m . Find the area of the shaded region. Use the value 3.14 for , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
21.07 m²
Step-by-step explanation:
Please find the complete question in the attached image
Area of shaded region = area of rectangle - area of semicircle
Area of semicircle = [tex]\frac{1}{2}[/tex]πr²
π = 3.14
r = radius = 14/2 = 7m
the diameter of the semicircle is 14m , thus the radius would be half of the diameter
(1/2) x 3.14 x 7² = 76.93 m^
Area of a rectangle = length x width
width = radius of semicircle = 7
14 x 7 = 98 m²
Area of shaded region = 98 m² - 76.93 m^ = 21.07 m²

Answer:
0.50
Step-by-step explanation:
The question states at least 2 which means 2 or more.
The only applicable numbers to look at would be 2 and 3.
First of all we find 2 since it's missing.
Now all probability distributions must add up to 1.
As we can see there are 0.20, 0.30 and 0.40 which is equal to 0.90. Therefore 1 - 0.90 = 0.10 which would be 2.
Hence, the peobability that x is at least 2 is 0.10 + 0.40 = 0.50.
Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
Answer:
8 phone calls
Step-by-step explanation:
Eduardo spent 4 minutes on the phone while routing 2 phone calls. In all, how many phone calls does Eduardo have to route to spend a total of 16 minutes on the phone? Solve using unit rates.
From the above question:
4 minutes = 2 phone calls
16 minutes = x
Cross Multiply
4 minutes × x = 16 minutes × 2 phone calls
x = 16 minutes × 2 phone calls/4 minutes
x = 8 phone calls
Therefore,
Eduardo has to route 8 phone calls to spend a total of 16 minutes on the phone
Which fraction

1/3
Answer:
[tex]\frac{3}{1}[/tex]
Step-by-step explanation:
[tex]\frac{3}{1}[/tex] is equivalent to [tex]\frac{6}{2}[/tex] because 3 x 2 = 1 x 6 = 6. 93 is equivalent to [tex]\frac{6}{2}[/tex] because 9 x 2 = 3 x 6 = 18. 124 is equivalent to [tex]\frac{6}{2}[/tex] because 12 x 2 = 4 x 6 = 24.

Find the value of x and the value of y.
A. x=15, y=10√3
B. x 20, y=10√3
C. x=20√3 y=5√3
D. x =15, y = 5√3
9514 1404 393
Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3

Two solutions of different concentrations of acid are mixed creating 40 mL of a solution that is 32% acid. One-quarter o...
Answer:
See explanation below
Step-by-step explanation:
Question is incomplete. Here's the whole question:
"Two solutions of different concentrations of acid are mixed creating 40 ml of a solution that is 32% acid. one-quarter of the solution is made up of a 20% acid solution. the remaining three-quarters is made up of a solution of unknown concentration, c. equation can be used to determine c, the unknown concentration?
a) 30c + 10(0.2) = 40(0.32)
b) (c) + (0.2) = 40(0.32)
c) (c)( (0.2)) = 40(0.32)
d) 30(c)(10(0.2)) = 40(0.32)"
With this, we can now solve the question.
We have a solution that was made mixing2 different solutions of acid. In this case, we can assume the following:
Solution 1 = 40 mL 32% acid
Solution 2 = 1/4 solution 1, 20% acid
Solution 3 = 3/4 solution 1, c% acid.
Thus we can say:
Solution 1 = Solution 2 + Solution 3 (1)
Now, 1/4 of the volume of solution 1, means that we use 10 mL of a 20%acid, and the remaining 30 mL is the unknown acid.
With this, we can discart option b) and c) because these option are not considering the volume of solution 3 used. Option d is not doing any sum, only multiplications, so, this is not the option to use. We can easily say it's option a, but let's prove it.
In general terms, concentrations and volume are related, and if we have two solutions, the information of these two solutions must be conserved in the resulting solution. In other words:
M₁V₁ = M₂V₂
According to this, the concentration of the unknown acid would be:
30c + 0.2*10 = 40(0.32)
30c + 2 = 12.8
30c = 10.8
c = 0.36
Which means that the concentration of the acid is 36%
Hope this helps

Answer:
Step-by-step explanation:
Jackie you should know that the supplemental angles always add to 180° :)
That's like angles 1 & 2 or 55° & 1 . both are supplemental and add to 180°
Knowing this should make answering this pretty easy. :)
180 = ∠1 + 55
125 = ∠1
∠3 =∠1
∠2 = 55°
since line g is parallel to f , we know all the angles in the same places of line f are identical... got it?
