Step-by-step explanation:

Answer:

66%

Step-by-step explanation:

0.6 repeating is 66%.

From decimal to percent:

To get a percent from a decimal number, move the decimal over twice to the right. In this case, 0.66 would become 66% because the decimal moved to the right twice.

From decimal to fraction to percent:

I already know that 2 divided by 3 is 0.6 repeating. 2 divided by 3 could also be written as [tex]\frac{2}{3}[/tex]. So the first step is complete, from the decimal 0.6 repeating to the fraction [tex]\frac{2}{3}[/tex]. Now from [tex]\frac{2}{3}[/tex] to a percent. If you get a 2 out of 3 ([tex]\frac{2}{3}[/tex]) you would get a 66%.

Answer:

320 milligrams of sodium

Step-by-step explanation:

Create a proportion where x is the milligrams of sodium a 20 ounce bottle has:

[tex]\frac{96}{6}[/tex] = [tex]\frac{x}{20}[/tex]

Cross multiply and solve for x

1920 = 6x

320 = x

So, a 20 ounce bottle will have 320 milligrams of sodium

Answer:

[tex]V = 288\pi[/tex]

Step-by-step explanation:

Given

[tex]r = 6[/tex]

Shape: Sphere

Required

The volume

The volume of a sphere is calculated using;

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

Substitute 6 for r

[tex]V = \frac{4}{3}\pi * 6^3[/tex]

[tex]V = \frac{4}{3}\pi * 216[/tex]

Divide 216 by 3

[tex]V = 4\pi * 72[/tex]

[tex]V = 288\pi[/tex]

4) In spherical geometry, some quadrilaterals are parallelograms.

In spherical geometry, some quadrilaterals are parallelograms is a true statement. Thus option D is correct.

Instead of the sort of geometries studied in trigonometry or solid geometry, the research of shapes on a structure's surface. White lines are large rounds in spherical, therefore any three layers intersect at two locations.

A spherical quadrilateral is a bounded surface that is homomorphic to a compact disk. It has four distinct local maxima called extremities, a Riemannian measurement that has constant curvature 1 everywhere else, aside from the corners, and or the demarcation arcs between it intersections. a dome shape. the collection of rectangular shapes with specified angles.

Therefore, option D is the correct option.

Answer:

[tex]Area= 8[/tex]

Step-by-step explanation:

Given

[tex]I = (-9,-8)[/tex]

[tex]J = (-5,-6)[/tex]

[tex]K = (-7,-3)[/tex]

The complete part of the question is to calculate the area of IJK

The area is calculated using:

[tex]Area = \frac{1}{2}|x_1y_2 - x_2y_1 + x_2y_3 - x_3y_2 + x_3y_1 - x_1y_3 |[/tex]

Where:

[tex]I = (-9,-8)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]J = (-5,-6)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]K = (-7,-3)[/tex] --- [tex](x_3,y_3)[/tex]

So, we have:

[tex]Area = \frac{1}{2}|(-9*-6) - (-5*-8) + (-5*-3) - (-7*-6) + (-7*-8) - (-9*-3) |[/tex]

Solve the brackets

[tex]Area = \frac{1}{2}|54 - 40 + 15- 42 + 56 - 27 |[/tex]

[tex]Area = \frac{1}{2}|16|[/tex]

The absolute value of 16 is 16

So:

[tex]Area = \frac{1}{2} * 16[/tex]

[tex]Area= 8[/tex]

Answer:

[tex]81\pi[/tex]

Step-by-step explanation:

Area = pi*r^2

Area = pi*9^2

Area = [tex]81\pi[/tex]

Answer:

81πyd²

Step-by-step explanation:

Given

Radius of the circle (r) = 9 yd

Area of the circle

Answer:length of the east side=3.075km

Step-by-step explanation:

The west  side of Ms. Hammond's ranch=2.6 km long.

The  east side of Ms. Hammond's ranch = 475 m longer than the west side

Therefore East side =2.6 km +475 m

Changing 2.6 kmto m becomes  2.6 x1000=2600m

East side =2600m +475 m=3075m

3075m to km becomes 3075m/1000 =3.075km

Part 1

Ying is correct while Jabbar is incorrect. The polar form would have cosine listed first, then sine later. The sine term always has the imaginary 'i' attached to it. It's fairly easy to mix these trig functions up. One way to remember is to think alphabetical order (C is before S, cosine before sine). Other than this difference, the two students have identical steps.

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

Part 2

Ying made the error this time. Jabbar is correct. When using a unit circle, you should find that

cos(pi/2) = 0

sin(pi/2) = 1

The point (x,y) on the unit circle that corresponds to the angle theta will help us see this. Note how x = cos(theta) and y = sin(theta).

Side note: Jabbar now has the correct order of cosine and sine (see part 1 above).

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

Part 3

Ying made the error of adding the r values. Instead, you should multiply them like Jabbar did. The theta angle values are the terms we add up. An interesting thing to notice is that Ying computed cos(pi/2) = 0, which contrasts to the mistake made in part 2.

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

Part 4

Ying is correct. You divide the r values, and the order of division is important. The order of division is from left to right. We have 7 on the left and -2 on the right, so that's why Ying ended up with the correct new r value of -7/2. Jabbar swapped the order incorrectly. The same issue shows up when subtracting the theta values. Keep in mind that the order of subtraction is important. Something like 2-3 = -1 is not the same as 3-2 = 1. Ying has the correct order of subtraction for those theta values.

Answer:

15 < X > 31

Step-by-step explanation:

From triangle theorem,a triangle with sides X, Y, Z, the sum of any 2 sides must be greater than the third side i.e;

1. X + Y > Z

2. Y + Z > X

3. X + Z > Y

We are given 2 sides say Y = 8 and Z = 23.

Thus,Range of values is expressed as;

Z - Y < X > Z + Y

23 - 8 < X > 23 + 8

15 < X > 31
