Answer:
b) -2x = 20, negative 2x is equal to 20
(Because, -2x = -20)
Step-by-step explanation:
Given equation,
→ 2x + 14 = 4x - 6
Now the value of x will be,
→ 2x + 14 = 4x - 6
→ 2x - 4x = -6 - 14
→ -2x = -20
→ x = (-20)/(-2)
→ x = 20/2
→ [ x = 10 ]
Hence, the value of x is 10.

The price of a cycle after allowing 15% discount and 13% VAT is Rs.19,323. Find the amount of VAT levied and marked price.
Answer:
Rs. 18936.54
Step-by-step explanation:
Given data
Discount=15%
VAT= 13%
Amount paid= Rs.19,323
The amount of VAT
=13/100*19323
=0.13*19323
= Rs. 2511.99
The amount of discount
=15/100*19323
=0.15*19323
= Rs.2898.45
The marked price is
=19323+2511.99-2898.45
=21834.99-2898.45
=Rs. 18936.54

Which of the the coordinates is equal to sin (4pi/5) ?
A) x-coordinate of point A
B) y-coordinate of point A
C) x-coordinate of point B
D) y-coordinate of point B
E) x-coordinate of point C
F) y-coordinate of point C
Answer:
Step-by-step explanation:
π/2 < 4π/5 < π
4π/5 is in Quadrant II
sin(4π/5) = y-coordinate of A
The coordinates is equal to sin(4π/5) = y-coordinate of A.
We need to find the coordinates is equal to sin (4pi/5).
Which trigonometric functions are positive in which quadrant?In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.
In second quadrant(π/2 < θ < π), only sin and cosec are positive.
In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.
In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.
Then, we have π/2 < 4π/5 < π
So, 4π/5 is in Quadrant II
Hence, the coordinates is equal to sin(4π/5) = y-coordinate of A.

If the lengths of the two legs of a right triangle are 12 and 16, what's the length of
the hypotenuse?
A) 28
B) 14
C) 16
D) 20
Answer:
c=20cm
Step-by-step explanation:
In a right triangle
a^2 +b^2 =c^2
Where c is length of hypotenuse.
⟹12^2 +16^2 =c^2
c^2 =144+256
c^2 =400

A vessel without a lid has the shape of a cylinder. The height of the vessel is 1.5 m, and the diameter of the base represents 40% of the height. Determine if 1 kg of paint is enough to completely paint the vessel inside and out, if it is known that for 1 square meter of surface 150g of paint is consumed.
Answer:
Yes, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.
Step-by-step explanation:
For the given vessel without a lid,
diameter = 0.4 x 1.5
= 0.6 m
radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{0.6}{2}[/tex]
= 0.3 m
Total external surface area of the vessel = 2[tex]\pi[/tex]rh + [tex]\pi[/tex][tex]r^{2}[/tex]
= [2 x [tex]\frac{22}{7}[/tex] x 0.3 x 1.5] + [[tex]\frac{22}{7}[/tex] x [tex](0.3)^{2}[/tex]]
= 2.8286 + 0.2829
= 3.1112
Total external surface area of the vessel is 3.1112 square meter.
Total internal and external surface area = 2 x 3.1112
= 6.2224 [tex]m^{2}[/tex]
But for 1 square meter, 150 g of paint is consumed. Thus;
for 6.2224 [tex]m^{2}[/tex] = 6.2224 x 150 g
= 933.36 g
Thus, 6.2224 [tex]m^{2}[/tex] of area would require 933.36 g of paint.
So that,
[tex]\frac{933.36}{1000}[/tex] = 0.93336 kg
Therefore, 1 kg of paint is enough to completely paint the inside and outside surfaces of the vessel.

find the factors of each number. Write the common factor ( CF ) and then state the greatest common factor ( GCF) .
Given:
Two numbers are 12 and 21
To find:
The factors of 12 and 21, then find the common factor and the greatest common factor.
Solution:
Two numbers are 12 and 21. The prime factors of these two numbers are
[tex]12=2\times 2\times 3[/tex]
[tex]21=3\times 7[/tex]
From the above factorization, it is clear that the factor 3 is common in both. So,
Common factor (CF) = 3
Only 3 is common in factorization of both. So,
Greatest common factor (GCF) = 3
Therefore, the common factor is 3 and the greatest common factor is also 3.

Choose the number that is 7.648 rounded to the nearest hundredth
Answer:
7.65
Step-by-step explanation:
because 4 is the hundredths place so you look to the right and the number 8 is more so you round it and you get 5 so its 7.65
The number that equivalent to after rounding off to nearest hundred will be 7.65 .
Given,
Number = 7.648
Here,
The concept of rounding off:
When the digit after decimal is greater than 5 then it can be rounded off to its next value .
If the digit is less than 5 then it can be rounded to its previous value .
So,
The number is 7.648 .
Rounding off to its nearest hundred .
Clearly we can round off the number to its nearest hundred ,
Rounding off to nearest hundred= 7.65

Find the missing parts of the triangle. Round to the nearest tenth when necessary or to the nearest minute as appropriate.
a = 8.1 in.
b = 13.3 in.
c = 16.2 in.
A = 31.9°, B = 52.8°, C = 95.3°
No triangle satisfies the given conditions.
A = 29.9°, B = 54.8°, C = 95.3°
A = 27.9°, B = 54.8°, C = 97.3°
I think it might be B
Answer:
Step-by-step explanation:
Use the Law of Cosines to find the measure of angle A from the lengths of the sides.
A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°
B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°
C = 180 - A - B = 95.3°

Answer: $4110.8 (more likely - 95% sure) or $2,107 (less likely)
Step-by-step explanation: It could be $4110.8 because you have the take the total they made and subtract is from the cost of the toys ($7,230-$2,450=$4,780). Then you have to take the result of that and get 14% of it, then subtract that from the $4,780 amount. Then you get the final answer which is $4110.8.
However, it could also be $2,107 because the question itsn't that clear in the second sentence. It could be saying that $2,450 is the price of the toys (which is what I assumed above), or that it is the profit that the $2,450 (which I used below). I think that the above answer is more likely because if not then the first number would never be used. Anyways here is the second way it could be.
Step-by-step explanation: It could be $2,107 because you take the profit ($2,450) and get 14% of it, then subtract that from the $2,450 amount. Then you get the final answer which is $2,107.
If I was you, I would do the first one ($4110.8) because I really think it is that one. I just put the other one here just in case.

Answer:
24°
Step-by-step explanation:
[tex]r \degree = 180 \degree - (34 + 122) \degree \\(vertical \: \angle s) \\ \\ r \degree = 180 \degree - 156 \degree \\ \\ r \degree = 24 \degree \\ \\ r = 24[/tex]
Answer and Step-by-step explanation:
The answer is 24 degrees.
We see the angle 34 and 122. To find that angle in between, we subtract those numbers from 180.
180 - 34 - 122 = 24 = r
By the vertical angles theorem, r is equal to 24.
