A whole turn is 360° so to turn 40° clockwise is equivalent to turn 320° counterclockwise.

The total angle around a point is 360 degrees

If we have a clockwise rotation of 40 degrees, then the converse of this must me done in the counter clockwise direction in order to achieve the same angle

To do the converse we should move a total of 360 - 40 degrees in the counter clockwise direction because the total is 360 degrees

Converse move = 360 - 40 = 320 degrees

So, a 320 degree counter clockwise move would be equal to a clockwise move of 40 degrees

Answer:

The new pressure of the gas is 42 pounds per square inches.

Step-by-step explanation:

When the temperature remains constant, the volume of a gas is inversely proportional to the pressure of the gas.

$V\propto \frac{1}{P}$

We can rewrite the above equation is

$\frac{V_1}{V_2}=\frac{P_2}{P_1}$ [at constant temperature]

At a pressure of 14 pounds per square inches, a balloon is filled with 93 cubic inches of gas.

The volume of the gas is decreased to 31 cubic inches.

Here,

$V_1$ = 93 cubic inches, $P_1$ = 14 pounds per square inches,

$V_2$ =31 cubic inches, $P_2$ = ?

$\frac{V_1}{V_2}=\frac{P_2}{P_1}$

$\Rightarrow \frac{93}{31}=\frac{P_2}{14}$

$\Rightarrow \frac{P_2}{14}=\frac{93}{31}$

$\Rightarrow {P_2}=\frac{93}{31}\times 14$

$\Rightarrow {P_2}=42$ pounds per square inches

The new pressure of the gas is 42 pounds per square inches.

Angle 3 is 65 degrees. Identify all the other angles that measure 65 degrees.

Bas_tet [7]

Angles 2, 6, and 7 because angle 1 = 115 so that makes angle 4 = 115 so angle 2 must also be 65 so angle 4 and 2 = 180 and the same goes for angles 5,6,7,8

45 + 60 = 15 x ___ + 15 x ___

tia_tia [17]

Answer:45+60=15x+15x

Step 1: Simplify both sides of the equation.

45+60=15x+15x

(45+60)=(15x+15x)(Combine Like Terms)

105=30x

Step 2: Flip the equation.

30x=105

Step 3: Divide both sides by 30.

30x/30= 105/30

x= 7/2

Answer:

x= 7/2
