now you want to multiply 20x3

which will get you 60 meters

Answer 2

Answer: 60 meters

Step-by-step explanation: you can divide 20 by 15 to get 3/4 and 3/4 times 45 is 60

oof sorry if its wrong or the explanation is too lazy

Answers

Answer:

Step-by-step explanation:

do this is 2 parts

total = square + 1/2 circle

area of a square is side * side or  ... b/c the sides of a square are the same 2* side

area of a circle is Pi* r^2

total area = 12*12 + 1/2 * pi * 6^2

4x-9=2x+5..solve for X..Help?

Answers

Answer:

x = 7

Step-by-step explanation:

4x - 9 = 2x +5        add 9 from both sides

4x = 2x +14            subtract 2x from both sides

2x = 14.                   divide both sides by 2

x = 7

Answer:

x = 7

Step-by-step explanation:

Rewrite equation

4x - 9 = 2x + 5

Add 9 on both sides

4x -9 +9 = 2x + 5 + 9

Simplify

4x = 2x + 14

Subtract 2x on both sides

4x - 2x = 2x + 14 - 2x

2x = 14

Finally divide both sides by 2

2x/2 = 14/2

x = 7

tan = opposite / adjacent

tan x = 4/9

x = tan^-1 (4/9)

x = 23.9624....

x = 24.0

Answer:

66.03 so 70

Step-by-step explanation:

since hypotunees has no value it cancels.

aso it leaves with an adjacent and oppisite

using trig function you will get

tan(x)=(9/4)

inverse tan to get x on its own

(x)=tan^-1(9/4)

put that on the calculater and you will get the angle

therefore

(x)=66.04 round it the nearest ten which is

The volume of a sphere can be determined by the formula V = 4/3 πr^3, where r is the radius. What is the volume of a sphere with radius 3/2x^3y^–2 in terms of x and y?

Answers

Answer:

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]

Step-by-step explanation:

Given

[tex]V = \frac{4}{3}\pi r^3[/tex]

Required

Find V when

[tex]r = \frac{3}{2}x^3y^{-2[/tex]

Substitute [tex]\frac{3}{2}x^3y^{-2[/tex] for r in [tex]V = \frac{4}{3}\pi r^3[/tex]

[tex]V = \frac{4}{3}\pi * (\frac{3}{2}x^3y^{-2})^3[/tex]

Open bracket

[tex]V = \frac{4}{3}\pi * \frac{3}{2}^3 * x^{3*3}y^{-2*3}[/tex]

[tex]V = \frac{4}{3}\pi * \frac{27}{8} * x^{9}y^{-6}[/tex]

Simplify the fractions

[tex]V = \pi * \frac{9}{2} * x^{9}y^{-6}[/tex]

Let

[tex]\pi = \frac{22}{7}[/tex]

So:

[tex]V = \frac{22}{7} * \frac{9}{2} * x^{9}y^{-6}[/tex]

[tex]V = \frac{11}{7} * \frac{9}{1} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} * x^{9}y^{-6}[/tex]

[tex]V = \frac{99}{7} x^{9}y^{-6}[/tex]

HELP ME ASAP BRAINLY :)) How many sides does a polygon have if its total interior angle sum is 4 times its total exterior angle sum?

Answers

Answer:

Step-by-step explanation:

If you are given the interior angle, just subtract that from 180 to get the exterior angle and then use the number of sides = 360 / exterior angle to find the number of sides. it's much easier. the number of sides is equal to 10. the sum of the interior angles is equal to 10 * 144 = 1440 degrees.
10 x 144 so that would be 1440

Dan is driving from his hometown in California to Colorado for a ski vacation. The equation defines the distance he is from home h hours after noon. What are the meanings of the values in the equation?

Dan is 110 miles from home at noon and is traveling at 55 miles per hour.
Dan is 55 miles from home at noon and is traveling at 110 miles per hour.
Dan leaves at noon and is traveling at 110 miles per hour.

Answers

Answer:

Dan is 110 miles from home at noon and is traveling at 55 miles per hour

Step-by-step explanation:

Mathematically, we have the general equation of a linear model as;

y = mx + b

m represents the slope of the model

b is the y-intercept of the model

Mathematically, what we have here is that there is a plot of distance against time

Distance is on the y-axis

time is on the x-axis

Now, the coefficient of the x-axis value is the slope

From what we have, the slope value is 55 miles per hour

Now, we have the y-intercept at 110

So, what this mean is that the distance from home is 110

So the correct answer here is that;

Dan is traveling at 55 miles per hour and he is 110 miles away from home

Answer:

x = 7

Step-by-step explanation:

Given

3x - 5 = 16 ( add 5 to both sides )

3x = 21 ( divide both sides by 3 )

x = 7

Answer: X= 7

Explanation:
(you need to get x by its self)

Step 1- add the (-5) over to the 16

Because to get rid of a negative or minus sign you need to do the opposite which is addition.

You’ll get: 3x=21

Step 2- divide the 3 off from 21
Because the ‘3x’ is acting as multiplication, and the opposite of multiplication is division

You’ll get: X=21/3
Which is X=7

Answer: 41

Step-by-step explanation:

You need to subtract the 82 by the 41 so 82-41 then you would find the missing part. Or you could add 4 to the 4 to make 8 and then add the 1 to the 1 to get 2

Three of the four vertices of a rectangle are located at (4, 2), (7, 2) and (4, 8). a. What are the coordinates of the missing vertex? ( , ) b. Find the area and perimeter of the rectangle. Area = square units Perimeter = units

Answers

Answer:

a) The coordinates of the missing vertex = (7, 8)

b) Area = 18 square units

   Perimeter = 18 units

Step-by-step explanation:

a) We know three of the four vertices:

A: (4, 2)           C ______ D(?)

B: (7, 2)               |             |

C: (4, 8)           A |______| B  

To find the coordinates of the missing vertex we need to calculate the distance in the x-direction from point A to point B:

[tex] B_{x} - A_{x} = 7 - 4 = 3 [/tex]                    

Hence, the distance of point D from point C in the x-direction is:

[tex] D_{x} = C_{x} + 3 = 4 + 3 = 7 [/tex]

Now, to find the coordinate in "y" we need to calculate the distance in the y-direction between point C and point A:

[tex] C_{y} - A_{y} = 8 - 2 = 6 [/tex]  

Then, the distance of point D from point B in the y-direction is:

[tex] D_{y} = B_{y} + 6 = 2 + 6 = 8 [/tex]

Therefore, the coordinates of the missing vertex (point D) are:

[tex] D = (D_{x}, D_{y}) = (7, 8) [/tex]    

b) The area of the rectangle is:

[tex] a = (B_{x} - A_{x})*(C_{y} - A_{y}) = 3*6 = 18 units^{2} [/tex]

The perimeter is given by:

[tex] p = 2*(3 + 6) = 18 units [/tex]
