what is the value of n in the equation 2n+19=21
Step-by-step explanation:
[tex]2n + 19 = 21[/tex]
[tex]2n = 21 - 19[/tex]
[tex]2n = 2[/tex]
[tex]n = 2 \div 2[/tex]
Therefore, N = 1
hope it helps don't forget to like and mark me down
Answer:
n=1
Step-by-step explanation:
to solve this you put 19 on the opposite side and subtract 19 fron 21 because subtraction is the opposite of addition and then you get 2 and then divide 2 by 2 to get 1 so n=1. Yo can check it by doing 2*1=2 then 2+19 =21 so it is the correct answer.

[tex]162\sqrt{3}[/tex]
Step-by-step explanation:
The equation for finding the area of a hexagon with a side length is
[tex](s^23\sqrt{3} )/2[/tex]
insert [tex]6\sqrt{3}[/tex]
and you are left with 162\sqrt{3}
Hope that helps :)
Answer:
[tex] \displaystyle E)\: 162 \sqrt{3} [/tex]
Step-by-step explanation:
we are given a side a polygon
and said to figure out the area
recall the formula of regular polygon
[tex] \displaystyle \: \frac{ {na}^{2} }{4} \cot \left( \frac{ {180}^{ \circ} }{n} \right) [/tex]
where a represents the length of a side
and n represents the number of sides
the given shape has 6 sides
and has a length of [tex]\displaystyle 6\sqrt{3}[/tex]
so our n is 6 and a is 6√3
substitute the value of n and a:
[tex] \displaystyle \: \frac{ {6 \cdot \:( 6 \sqrt{3} })^{2} }{4} \cot \left( \frac{ {180}^{ \circ} }{6} \right) [/tex]
reduce fraction:
[tex] \displaystyle \: \frac{ {6 \cdot \:( 6 \sqrt{3} })^{2} }{4} \cot \left( \frac{ { \cancel{180}^{ \circ}} ^{ {30}^{ \circ} } }{ \cancel{6 \: } } \right) [/tex]
[tex] \displaystyle \: \frac{6 \cdot \: (6 \sqrt{ {3} } {)}^{2} }{4} \cot( {30}^{ \circ} ) [/tex]
simplify square:
[tex] \displaystyle \: \frac{6 \cdot \: 36 \cdot \: 3 }{4} \cot( {30}^{ \circ} ) [/tex]
reduce fraction:
[tex] \displaystyle \: \frac{6 \cdot \: \cancel{36} \: ^{9} \cdot \: 3 }{ \cancel{ 4 \: } } \cot( {30}^{ \circ} ) [/tex]
[tex] \displaystyle \: 6 \cdot \: 9 \cdot \: 3 \cot( {30}^{ \circ} ) [/tex]
simplify multiplication:
[tex] \displaystyle \: 162\cot( {30}^{ \circ} ) [/tex]
recall unit circle:
[tex] \displaystyle \: 162 \sqrt{3} [/tex]
hence, our answer is E
1. The following data represents the number of calories in seven sandwiches
at the restaurant: {740, 610, 490, 370, 500, 510, 460}. Find the mean
absolute deviation. Round your answer to the nearest hundredth.
Answer:
3710
Step-by-step explanation:
The mean absolute deviation of the seven sandwiches is 85.31 calories.
What is mean?Mean is the average of a group of numbers. The mean absolute deviation (MAD) is calculated using:
[tex]MAD=\frac{\Sigma_{i=1}^n|x_i-mean|}{n} \\\\Mean=\frac{740+610+490+370+500+510+460}{7}= 525.71\\\\MAD=\frac{|740-525.71|+|610-525.71|+|490-525.71|+|370-525.71|+|500-525.71|+\\|510-525.71|+|460-525.71|}{7} \\\\\\MAD=85.31[/tex]

The correct option is Option A: The solution of the quadratic equation is x= -4 and 1.
What is the quadratic formula?The quadratic formula is the method for solving and finding the solution of the quadratic equation ax²+bx+c=0.
The solution of the quadratic equation ax²+bx+c=0. by the quadratic formula is given by
x= {-b±√(b²-4ac)}/2a
Here b²-4ac is discriminant denoted by D.
D= b²-4ac
Given the quadratic equation is
x²+3x-4=0
for solving by the quadratic formula
comparing the above equation by ax²+bx+c=0
a=1
b=3
c=-4
The solution of this quadratic equation will be
x= {-b±√(b²-4ac)}/2a
⇒x= {-3±√(3²-4.1.(-4))}/2.1
⇒x= {-3±√(9+16)}/2
⇒x= {-3±√25}/2
⇒x=(-3±5)/2
⇒x= (-3+5)/2 OR (-3-5)/2
⇒x= 2/2 OR -8/2
⇒x=1 or -4
By checking all the options
Therefore the correct option is Option A: The solution of the quadratic equation is x= -4 and 1

x is an odd number and the sum of the next two consecutive even numbers is less than 90.
By forming an inequality in terms of x, find the largest possible odd number of x.
Answer:
41
Step-by-step explanation:
Let the odd number be x
Therefore,
[tex](x + 1) + (x + 3) < 90 \\ 2x + 4 < 90 \\ 2x < 86 \\ x < 43[/tex]
Therefore, Largest possible odd number of x is 41

A car accelerates from rest to 25 miles per hour in 3.0 seconds. What was the car's
acceleration?
Answer:
The car's acceleration was 3.73 metre per second square = 3.73m/s²
Step-by-step explanation:
The car accelerated from rest.
initial velocity (u) = 0m/s
final velocity (v) = 25miles/hr = 11.2m/s
time (t) = 3s
a = ?
v = u+at
a = (v-u)/t
a = (11.2 - 0) / 3
a = 11.2/3
a = 3.73
a = 3.73m/s²

TJ's Cat Food plans to use tins that are the shape of cylinders. Find the height of the tin, if its bottom diameter is 12 cm and volume is 757.36cm.
Answer:
6.69 cm
Step-by-step explanation:
Given data
Diameter= 12cm
Radius= 6cm
Volume= 757.36cm^3
The expression for the volume of a cylinder is
V= πr^2h
Substitute
757.36= 3.142*6^2*h
757.36=113.112h
h= 757.36/113.112
h= 6.69 cm

the number a is smaller than the number b by 1/5 of b. by what part of a is b bigger than a?
A is smaller by 1/5 of b
So if you add a and 1/5 of b you would have b:
a + 1/5b = b
Solving for a you have:
A = b - 1/5b = 4/5b
A = 4/5b
Solving for b divide both sides by 4/5:
B = 5/4a
Since 4/4 = 1, this means b I’d bigger than a by 1/4
