3 0

Answer:

7.2

Step-by-step explanation:

1. Natalie needed 40 minutes to get to school. In hours 40 minutes is 40/60= 2/3 hour (because there are 60 minutes in an hour). so her speed is 14.4/(2/3)= 14.4*3/2= 21.6 mph.

2. Britany needed 40+20= 60 min. 60 min= 1 hour. so she needed 1 hour her speed is 14,4/1= 14.4mph

3. The difference 21.6-14.4=7.2 is the answer .

Ali’s wage was increased from 120$ to 132$ per week. find the increase as fraction on its simplest form, as a percentage of the
Anettt [7]
Well the increase is 132/120. Simplify by dividing 12 from the numerator and the denominator, you should get 11/10.
11/10 is also 110%

A craftsman makes a circular table with a radius of 55
Rudik [331]

Answer:

Hey mate here is your answer...

Step-by-step explanation:

smaller circular table to be made

with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm

therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm

circumference of circle = 2πr

= 2*3.14*27.5

= 172.7 cm = 27.5cm

hope it helps you ❣️

Which polynomial represents the difference below? (8x^2+9)-(6x^2+2x+2)
grin007 [14]

Answer:

The polynomial is  2 x² - 2x + 7

Step-by-step explanation:

Given polynomial

                   (8 x² + 9 ) - (6x² +2x +2)

           =   8 x² +9 - 6x² - 2x -2

          =    8x² - 6x² - 2x + 9-2

         =    2 x² - 2x + 7

The polynomial is   2 x² - 2x + 7

What is the angular velocity of a 6–foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for π.
irakobra [83]
The angular velocity is the linear speed divided by the radius.
  ω = d/(t*r) = (14.13 ft)/((3 s)*(6 ft))
  ω = 0.785 radians/second
There are 180/π degrees per radian, so the angular velocity can also be written as ...
  ω = 45 degrees/second
