Yes I would replace a small car that gets 33 mpg with a hybrid that gets 50 mpg because it is more fuel efficient and cheaper on fuel

(−2 − √3)(−2 + √3) simplified​
nata0808 [166]

Answer:

1

Step-by-step explanation:

To simplify this, we can use foil:

  • First: -2 × - 2 = 4
  • Outside: -2 × √3 = -2√3
  • Inside: -√3 × -2 = +2√3
  • Last: -√3 × √3 = -3

From this, we get 4 - 2√3 + 2√3 - 3 which can be simplified to 1

Hope this helps!

Write a sentence that describes the relationship between the dependent variable and the independent variable. (Hint: Ratio langu
kodGreya [7K]

The dependent and the independent variable in the relationship y=60x are y and x respectively.

<h3>
What are Independent and dependent variables?</h3>

The Independent variables are variables whose value does not depend on any other variable. And it causes the change in other variables.

The dependent variable is those variables whose value is not independent and change in this variable is dependent on the change of the independent variable.

Given that you did 60 brush strokes in 1 minute. Therefore, the rate can be written as,

Rate = 60 strokes per minute

Now, the number of stokes in x minutes can be written as,

y = 60x

where y is the number of stokes,

x is the number of minutes

In the above relation, y is the dependent variable because its numerical value depends on time, while x is the independent variable.

Hence, The dependent and the independent variable in the relationship y=60x are y and x respectively.

Tammy is at the dentist's office waiting on her appointment. She notices that the 6-inch-long minute hand is rotating around the
swat32
There are 12 five minutes in one hour and 1 hour correspond to 360°, then each 5 minutes represents 360/12 = 30°

From 1:20 to 1: 55 we have 35 minutes or 7 x 5 minutes or

7 x 30° = 210° 

To convert degree into radian, we apply the following formula:

degree/180° = radian/π

210/180 = r/π or (cross multiplication) →Radian = (π x 210/180

→ Radian = 7π/6 (simplify by 30)
