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

Answer:

-32

Step-by-step explanation:

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

The answer = 1/4

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

Answer:

So the slope in this case is m = -2. Using point (0, 7) and m =-2 with point-slope we have y - 7 = -2(x-0) => y = -2x +7. Then we realize (0,7) actually is the y-intercept. We could have gone directly to y = -2x + 7. If we use (3,1) and m = -2 we get y-1=-2(x-3) => y -1 = -2x+6 => y = -2x+7. Another way to find y-intercept is to use y = mx +b directly. If we use the point (3,1) that means when x=3, y = 1. So 1=-2(3) + b => 1=-6+b => b = 7. So, y = -2x+7. Same result in all cases. I like to use point-slope. Others prefer to use y = mx+b, substituting for x, y, and m to solve for b.

The  mean absolute deviation of the seven sandwiches is 85.31 calories.

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.

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

Step-by-step explanation:

The equation for finding the area of a hexagon with a side length is

and you are left with 162\sqrt{3}

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
