Which equation can be used to solve for angle N in the triangle below?
A. 6.2^2 = 3.6^2 + 4.3^2 - 2(3.6)(4.3)cosN
B. 6.2^2 = 3.6^2 + 4.3^2 + 2(3.6)(4.3)cosN
C. 6.2^2 = 3.6^2 + 4.3^2 - (3.6)(4.3)cosN
D. 6.2^2 = 3.6^2 + 4.3^2 + (3.6)(4.3)cosN
Option A:
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
Solution:
Given data:
MO = 6.2 cm
ON = 4.3 cm
MN = 3.6 cm
To find the equation to solve for angle N:
Using cosine formula,
[tex]c^{2}=a^{2}+b^{2}-2 a b \cdot \cos C[/tex]
Here, a = 3.6 cm, b = 4.3 cm, c = 6.2 cm, and angle A = angle C
Substitute these in the formula, we get
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
The equation used to solve for angle N is
[tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]
Hence option A is the correct answer.
WXYZ is a trapezoid with WX ≅ YZ. Isosceles trapezoid W X Y Z is shown. Sides X Y and W Z are parallel. The length of X Y is 3 a minus 4 and the length of W Z is 3 a. Sides W X and Y Z are congruent. The length of W X is 2 a minus 2 and the length of Y Z is a + 1. What is the length of XY? 3 units 4 units 5 units 6 units
Answer: 5 units
Step-by-step explanation:
Based on the definition of an isosceles trapezoid, the length of XY is: 5 units.
What is an Isosceles Trapezoid?An isosceles trapezoid is a trapezoid that has two legs that are congruent.
Therefore:
2a - 2 = a + 1
Add like terms
2a - a = 2 + 1
a = 3
XY = 3a - 4
Plug in the value of x
XY = 3(3) - 4
XY = 5 units
Therefore, based on the definition of an isosceles trapezoid, the length of XY is: 5 units.

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone?!
2 cm
3 cm
4 cm
5 cm
Answer:
Step-by-step explanation:
VC = (1/3)·pi·r2·h
VC = volume of a cone
r = radius of base of cone = 6 cm
h = height
VC = (1/3)·pi·62·h
VC = 12·pi·h
VS = (4/3)·pi·r3
VS = volume of a sphere
r = radius of base of sphere = 3 cm
VS = (4/3)·pi·33
VS = 36·pi
Since the volume of the cone and the sphere are equal:
VC = VS
12·pi·h = 36·pi
Solve for h.

What is the GCF of 5 , 6 , and 8
Answer:
The GCF of 5, 6, and 8 would be 1.
Step-by-step explanation:
To find the GCF (Greatest Common Factor) of any amount on numbers, you would find the factors of the numbers and find which is the greatest one that they have in common.
To find the GCF of 5, 6, and 8, we must first find the factors of 5, 6, and 8.
Factors of 5: 1, 5
Factors of 6: 1, 2, 3, 6
Factors of 8: 1, 2, 4, 8
Now we found the factors of 5, 6, and 8. to find the GCF, we must now find which factors they have in common.
The factors 5, 6, and 8 have in common is 1. Since they have no other factors in common, 1 would be the GCF.
The GCF of 5, 6, and 8 would be 1.
I hope this helps. :)
Final answer:
The Greatest Common Factor (GCF) of the numbers 5, 6, and 8 is 1, as it is the only common factor among all the numbers.
Explanation:
The Greatest Common Factor (GCF) of the numbers 5, 6, and 8 is found by determining the largest number that divides each of the given numbers without leaving a remainder. To find the GCF, we can list the factors of each number:
Factors of 5: 1, 5Factors of 6: 1, 2, 3, 6Factors of 8: 1, 2, 4, 8Looking at the factors, 1 is the only number that is common to all three, making it the GCF.
Hence, the GCF of 5, 6, and 8 is 1. This methodically derived GCF encapsulates the common factor that unifies the numerical trio.

Maya is working two summer jobs, making $7 per hour babysitting and $11 per hour landscaping. Last week Maya earned a total of $96 and worked 3 times as many hours babysitting as she worked hours landscaping. Determine the number of hours Maya worked babysitting last week and the number of hours she worked landscaping last week.
The number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively
Given:
Earnings for babysitting = $7
my Earnings for landscaping = $11
Total earnings = $96
Iet
number of hours babysitting = x
number of hours landscaping = y
y = 3 × x
y = 3x (1)
y = 3x (1)7x + 11y = 96 (2)
substitute (1) into (2)
7x + 11y = 96 (2)
7x + 11(3x) = 96
7x + 33x = 96
40x = 96
x = 96/40
x = 2.4 hours
substitute x = 2.4 into (1)
y = 3x (1)
y = 3(2.4)
y = 7.2 hours
Therefore, the number of hours Maya worked babysitting and landscaping last week is 2.4 hours and 7.2 hours respectively

(6x – 10)
x=
Answer:
First of all (3x + 50) is equal to (6x - 10) so (3x + 50) = (6x - 10) 3x + 50 = 6x - 10 60 = 3x 20 = x
Step-by-step explanation:
Answer:
Step-by-step explanation:
(3x + 50)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(6x + -10) = 0
Reorder the terms:
(50 + 3x)(-10 + 6x) = 0
Multiply (50 + 3x) * (-10 + 6x)
(50(-10 + 6x) + 3x * (-10 + 6x)) = 0
((-10 * 50 + 6x * 50) + 3x * (-10 + 6x)) = 0
((-500 + 300x) + 3x * (-10 + 6x)) = 0
(-500 + 300x + (-10 * 3x + 6x * 3x)) = 0
(-500 + 300x + (-30x + 18x2)) = 0
Combine like terms: 300x + -30x = 270x
(-500 + 270x + 18x2) = 0
Solving
-500 + 270x + 18x2 = 0
Solving for variable 'x'.
Factor out the Greatest Common Factor (GCF), '2'.
2(-250 + 135x + 9x2) = 0
Factor a trinomial.
2((-50 + -3x)(5 + -3x)) = 0

What's the value of x? 40000mg =10x g
The value of x is 4. So 40000 mg= 40 g.
Step-by-step explanation:
The given is 40000mg = 10x g
Step:1
Take given equation as equation (1)
40000 mg= 10x g.................(1)
where, X is known value.
Step:2
Standard value for mg to g for the purpose of conversion of units,
1 milligram = 0.001 gram (or)
1 gram = 1000 milligram
Step:3
From the standard data values,
= 40000 mg
it converted mg to g by dividing 1000
= [tex]\frac{40000}{1000}[/tex] g
= 40 g.......................(2)
Step:4
From the Equations (1) and (2),
40=10x
x=4
Result:
The value of x is 4. So, 40000mg = 40 g.
