If the flour to sugar ratio is 4 cups flour to 1 cup sugar, then how much sugar do you need if you only use 2 cups of flour?

you would need half a cup of sugar

Answer:

1/2 cup sugar

Step-by-step explanation:

If you write a proportion;

1:4=x:2

Solve:

What is the quotient-3/8/-1/4

Answer:

3/2

Step-by-step explanation:

The quotient -3/8 divided by -1/4 can be found by inverting the divisor (-1/4) and then multiplying:

-3 -4 12

------ * ------ = ------ = 3/2

8 1 8

The quotient of the given numbers -3/8 and -1/4 is 3/2.

Answer:

1 1/2

What kinds of symmetry do these letters and numbers have? Choosing best answer? What kind(s) of symmetry do these have? F 3 E Point, line, plane, or none?

Answers:

Letter F: none

Number 3: line and plane simmetry

Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180° returns the same original figure.

None of the objects given result the same when you rotate them 180°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

Letter F: none

Number 3: line and plane simmetry

Letter E: line and plane simmetry

Explanation:

1) point symmetry means that a rotation of 180° returns the same original figure.

None of the objects given result the same when you rotate them 180°, so none has point symmetry.

2) line simmetry is when the reflection accross a line returns the same original figure.

Both number 3 and letter E have symmetry accros a horizontal line that crosses them by the middle, which F does not.

3) Plane simmetry: exactly as with the line,number 3 and letter E have simmetry accross a plane that crosses them by the middle.

Which statement is true regarding DC current? A.The electrons move back and forth.

B.There can only be one voltage supplied.

C.A high voltage current can be transformed into a low voltage current.

D.A low voltage current can be transformed into a high voltage current.

E.This is what is sent from the power plants to your home.

Answer:

B.There can only be one voltage supplied.

Step-by-step explanation:

Moving electrons constitute current. When the electrons move in single direction, it is known as Direct current (DC). When the electrons move back and forth, it is known as Alternating current (AC).

Voltage transferred from the power plants to out home is in the form of AC. A high voltage AC can be converted to low voltage AC and vice-versa using transformer.

DC is used for very small power requirement as such in cells of clocks, remotes etc. One single voltage can be supplied using DC. It cannot be increased or decreased.

I think it's this answer C.A high voltage current can be transformed into a low voltage current.

If someone travels 20km in 30mins, what is their speed?

You are given a distance of 20 kilometers and time of 30 minutes. You are required to find for the speed of the travelling object. The equation for speed is distance over time. Speed is a scalar quantity. It tells you the direction of the travelling object. The solution in this problem is,

Speed = distance/time

Speed = 20 kilometers / 30 minutes

Speed = 2/3 kilometers per minute or 0.667 kilometers per minute

Therefore, the speed of the object is 0.667 km per minute.

Speed = distance/time

Speed = 20 kilometers / 30 minutes

Speed = 2/3 kilometers per minute or 0.667 kilometers per minute

Therefore, the speed of the object is 0.667 km per minute.
