Answer:

30 revolutions

Step-by-step explanation:

to calculate the revolution of the wheels in 66 metres we need to get the circumference

circumference = 2πr, r = radius (diameter divided by 2) but from the formula of circumference we ca rewrite it as πd= 3.14 x 70 = 219.8cm

next convert 66 metres to cm

100cm = 1m

x= 66m

cross multiply

x= 66m x100cm/1m= 6600cm

revolutions in 66metres = 6600cm/219.8cm = 30.0272975 ≅30 revolutions

V = (4,-3,5)
w = (2,6,-1)
z = (3,0,4)
u = 0.5 v - w + 2 z = 0.5 (4,-3,5) - (2,6,-1) + 2 (3,0,4)
= ( [0.5 * 4 - 2 + 2 *3] , [0.5*-3-6+2*0] , [0.5*5--1+2*4] )
= ( 6 , -7.5 , 11.5 )
The correct answer is option D

Two angles form a linear pair. The measure of one angle is 2/3 the measure of the other angle. Find the measure of each angle

Luba_88 [7]

Answer:

108° and 72°

Step-by-step explanation:

let one angle be x then the other angle is $\frac{2}{3}$ x

the sum of the 2 angles = 180°, hence

x + $\frac{2}{3}$ x = 180 ( combining the left side )

$\frac{5}{3}$ x = 180

multiply both sides by 3 then divide both sides by 5

5x = 540 ⇒ x = 108

the 2 angles are x = 108° and $\frac{2}{3}$ x = 72°

Answer:

the percent reduction is 33.6% and the number of people who were issued a parking ticket are 42.

Step-by-step explanation:

Given:

Last month in the village of 125 people were issued a parking ticket.

This month only 83 people were issued one.

Now, to find the percent reduction from this month to last month and the number of people who were issued a Parking ticket.

So, the reduction of the number of people who were issued a Parking ticket from this month to last month are:

125 people - 83 people = 42 people.

Thus, 42 people reduction from this month to last month.

Now, to get the percent reduction:

$\frac{42}{125}\times 100.$

$=\frac{4200}{125}$

$=\ 33.6\%$

Therefore, the percent reduction is 33.6% and the number of people who were issued a parking ticket are 42.
