Write the decimal as a percent
Answer:
3/5
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%.

A company sells fruit smoothies in two sizes: 6 ounces and 20 ounces. You know that a 6-ounce bottle contains 96 milligrams of sodium. If the amount of sodium is directly proportional to the fluid ounces of smoothie, how many milligrams of sodium does a 20-ounce bottle contain?
And can yall put an explanation please
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

What is the volume of the sphere in terms of ?
V =
.7 in 3
6 in.
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]

Please don't add any useless information to get points (THOSE WHO DO WILL GET REPORTED)
Thank you
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.

Triangle IJK, with vertices I(-9,-8), J(-5,-6), and K(-7,-3), is drawn on the coordinate grid below.
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]

The east side of Ms. Hammond's ranch is 475 m longer than the west side. The west side is 2.6 km long. What is the length of the east side in kilometers?
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

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
Jorge compre una televisión a un costo de 3450 el cual incluía el 40% de descuento cual seri el precio original de la televisión?
Answer:
Precio original= $5.750
Step-by-step explanation:
Dada la siguietne información:
Precio de venta= $3.450
Descuento= 40%
Para calcular el precio original (previo descuento), debemos usar la siguiente formula:
Precio original= precio de venta / (1 - porcentaje de descuento)
Precio original= 3.450 / (1 - 0,4)
Precio original= $5.750
