Refer to the Parallelogram below to complete the following problem if m angle B= 3x- 9 and m angle C= 39°, then what is the value of x?

Answer:

62.84

Step-by-step explanation:

Volume of both cones is approximately 12.57

formula= pi*r^2*h/3

Volume of the cylinder is approximately 37.7

formula= pi*r^2*h

you add the volumes

12.57+12.57+37.7

= 62.84

Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Answer:

D.) 400π

Step-by-step explanation:

The formula for the area of a circle is:

A = πr²

Substitute the radius into the equation:

A = πr²

A = π(20²)

Solve:

A = π(20²)

A = 400π

Therefore, the area of the circle is 400π square inches.

Answer:

3 gallons

Step-by-step explanation:

We need to find the area of the floor first:

25.6*15.2=389.12

Now we divide the surface area by gallons of polyurethane.

389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.

The 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, multiplication by a conversion factor.

We have:

32° 15' 66"

Here 15' represents the minute and 66" represents the seconds.

We know 1 degree = 60 minutes = 3600 seconds

15' in degree = 0.25 degree

66" in degree = 0.01833 degree

= 32 + 0.25 + 0.01833

= 32.268 ≈ 32.27 degree

Thus, the 32° 15' 66" is the same as 32.27 degree because 1 degree = 60 minutes = 3600 seconds.

y=3x−4

Step-by-step explanation:

find the tangent line to f(x)=x2−3x+5 at x=3

First, find the value of the function at the given point: y0=f(3)=5

Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point:  m=f′(3)

Find the derivative:  f′(x)=2x−3

Next, we evaluate the derivative at the given point to find the slope.

m=f′(3)=3

Finally, the equation of the tangent line is  y−y0=m(x−x0)

Plug the values that we found, we get that  y−(5)=3(x−(3))

So basically: y=3x−4

Volume fomula: V = wlh

V = volume

h = height

w = width

l = length

We are given these values:

V = 882

w = 14

l = 7

Solve for h in the orignal formula:

882 = (14)(7)h

882 = 98h

882/98 = 98h/98

9 = h

Therefore, the answer is [ 9cm ]

Answer:

He need to cover 275 miles for same cost for both plans

Step-by-step explanation:

Let x be the no. of miles

Case 1 :

Initial fee = $38

Additional cost of 1 mile = 0.13

Additional cost of x miles = 0.13x

So, total cost = 38+0.13x

Case 2 :

Initial fee = $49

Additional cost of 1 mile = 0.09

Additional cost of x miles = 0.09x

So, total cost = 49+0.09x

Now we are supposed to find amount of driving do the two plans cost the same

So, 38+0.13x=49+0.09x

0.13x-0.09x=49-38

0.04x=11

[tex]x=\frac{11}{0.04}[/tex]

x=275

Hence he need to cover 275 miles for same cost for both plans

The volume of the cylinder is approximately 351.9 cubic centimeters.

A cylinder is a 3-D figure that has a radius and a height.

The volume of a cylinder is given as πr²h.

Example:

The volume of a cup with a height of 5 cm and a radius of 2 cm is

Volume.

= 3.14 x 2 x 2 x 5

= 62.8 cm³

We have,

The volume of a cylinder can be calculated using the formula:

V = πr²h,

where r is the radius of the base and h is the height.

Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.

Substituting these values into the formula, we get:

V = π (4 cm)² (7 cm)

V ≈ 351.86 cm³

Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.

Therefore,

The volume of the cylinder is approximately 351.9 cubic centimeters.
