Solve for x. Round to the nearest tenth, if necessary.

2,094 cm^3

==========================================================

Explanation:

The diameter of 20 cm divides in half to the radius r = 10 cm.

The height is h = 20 cm.

V = volume of the cone

V = (1/3)*pi*r^2*h

V = (1/3)*pi*10^2*20

V = 2,094.3951023932 is approximate

I used my calculator's stored version of pi when computing the volume

That value then rounds to 2,094 cm^3 when rounding to the nearest whole number.

Answer:

-313 is the 64th term

Step-by-step explanation:

you take the second term an minus the first term with the second one {2-(-3)}

{=5} then you take two an minus five

it gives you -3 then you press minus five again it gives you negative eight then you press (equals to)until you reach the term you looking for

Answer:

B - In each round, the number of emails is 3 times the round before.

Step-by-step explanation:

This is because each time down, it is being multiplied by 3 again.

3

3 times 3 = 9

3 times 9 = 27 (can also be 3 times 3 times 3)

The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).

We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.

Given the following dimensions of the gift box:

s = 5.2 in.

b = 5.2 in.

h = 6.7 in.

Plug in the values into s² + 4(1/2bh):

Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).

Surface area of a square pyramid = 96.72 in.²

Therefore, the amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

the square root of 1728 is 41.57.

Answer:

41.57 is the answer.

Answer:

1.75 + 0.3x = 7.45; 19 minutes

Step-by-step explanation:

The cost of the phone call is found by 1.75 + 0.30 multiplied by the number of minutes the calls lasts.  The cost of the call is 7.45 so 1.75 + 0.3x = 7.45.  Begin by subtracting 1.75 from each side of the equation.  That leaves 0.3x = 5.7.  Then divide both sides by 0.3.  This gives x = 19.

Answer: 3.5 hours

Step-by-step explanation:

From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:

= 320 + 820

= 1140 calories

The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:

= 1140/326

= 3.5 hours

Answer:

(B)45°, 67.5°

Step-by-step explanation:

A regular polygon is a polygon in which all the sides are equal.

An Octagon is a polygon with 8 sides.

Since it is a Regular polygon, the following holds:

1.The Radii are equal

2. The angle Subtended by two radii are equal for all triangles in the octagon.

3. There are 8 Isosceles triangles in the octagon.

(a)Measures of angle formed by Two radii

From the centre of the octagon, there are 8 equal angles.

Sum of Angle at a point= 360°

Each Angle=360°÷ 8 = 45°

The measures of angle formed by two radii is 45°.

(b)a radius and a side of the polygon.

Since the triangles are Isosceles, the base angles at the side of the octagon are equal.

Let x be the angle made by a radius with a side.

From (a) above,

x+x+45°=180°(Sum of Angle in a Triangle)

2x=180-45°

2x=135°

x=135°÷2=67.5°

The angle between a radius and a side of the polygon is 67.5°.

Answer:

Chicago

Step-by-step explanation:

Compare the temperatures:

-4, -14, -11, -13

Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.

So, -13, -11, and -4 are all greater than -14.

And the lower the temperature, the colder it is.

Thus, Chicago is the coldest.

3. 3x = 12

An open statement in math means that it utilizes variables, and can only be concluded as being "true" or "false". The problem would result in asking whether or not it is always true or not. In this case, x will be true when you plug in 4, however, it will not be true when you plug in any other number. Therefore, it is a closed statement that can be falsified.

4. Open.

The statement can be true if the variable g is 35, however, it is false if it is not. An open statement concludes that it may or may not be correct, thereby being open.

Write the equation of line in slope-intercept form. Line parallel to y = 0.5x + 3 that passes through the point (−9,12)

Answer:

y - 12 = 0.5(x + 9)

Step-by-step explanation:

We want to find the line parallel to y = 0.5x + 3 that passes through the point (−9,12).

To some this, we will use the equation;

y - y1 = m(x - x1)

Here, x1 = -9, y1 = 12, m = 0.5

Thus;

y - 12 = 0.5(x - (-9))

y - 12 = 0.5(x + 9)
