Find JK................
Answer:
24 unit
Step-by-step explanation:
From the question,
JK = 2×NK.................... Equation 1
Using pythagoras theorem,
a² = b²+ c²................. Equation 2
From the diagram,
a = 15 unit, b = 9 unit, and c = NK
Substitute these values into equation 2
15² = 9²+(NK)²
Solve for NK
225 = 81+(NK)²
(NK)² = 225-81
(NK)² = 144
NK = [tex]\sqrt{144}[/tex]
NK = 12 unit.
Substitute these value of NK into equation 1
JK = 2×12
JK = 24 Unit.

m<3 = 97
m<10 = 97
m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.

Answer:
A number that can be made by dividing two integers (an integer is a number with no fractional part). The word comes from "ratio". But π (pi) is not a rational number, it is an "Irrational Number".
Step-by-step explanation:
mark me please
Answer:
Since rational numbers are all numbers that can be written as a fraction, and includes positive numbers, negative numbers and the 0. We can conclude that since -3.4 can be written as a fraction it is a rational number.

Step-by-step explanation:
Use the following diagram to find the angle measures of the triangle, rounded to the nearest degree.
m∠A=
m∠B=
m∠C=
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]
[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint does neil have
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint
A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it
sets the price at x dollars, it will sell f(x) = 4,920 - 6x phones. Therefore, the company's revenue is x . (4,920 - 6x). Find
the price x that will maximize the company's revenue.
Answer:
410
Step-by-step explanation:
Revenue is given by the relation :
x . (4,920 - 6x)
F(x) = 4920x - 6x²
To obtain the price, x which maximizes revenue, we take the first derivative of the revenue function and equate to 0
F'(x) = 0
F'(x) = 4920 - 12x
4920 - 12x = 0
-12x = - 4920
x = 4920 / 12
x = 410
Price will be 410

Answer:
-10/7
Step-by-step explanation:
w - 5 = 8w + 5
w - 8w = 5 + 5
-7w = 10
w = - 10/7
Answer:
Step-by-step explanation:
To solve this equation, group like terms together: 'w' terms on the right and constants on the left:
-10 = 7w. Then:
w = -10/7 (exact) or w ≈ 1.43
Find the surface area of the right cone. Round your answer to the nearest hundredth.
The solution is, the surface area of the right cone is 602 cm^2.
What is surface area of a cone?The surface area of a cone is equal to the curved surface area plus the area of the base: π r 2 + π L r , \pi r^2 + \pi L r, πr2+πLr,
where r denotes the radius of the base of the cone, and L denotes the slant height of the cone.
here, we have,
Given that,
The slant height of the cone, l = 16 cm
The radius of the cone, r = 8 cm
The height of the cone is :
h² = l² - r²
or, h² = 16² - 8²
= 192
or, h = √192
= 13.85
now, we know that,
The surface area of the cone is given by :
SA = πr² + πrl
=200.96 + 401.92
= 601.93
=602
Hence, the surface area of the right cone is 602 cm^2.
