Answer:

(D) The volume of Model A and B combined is 88 cubic centimeters.

Step-by-step explanation:

Volume of Model A

= 6 x 4 x 2

= 48 cm³

Volume of Model B

= 5 x 2 x 4

= 40 cm³

Volume of Model A and B

= 48 + 40

= 88 cm³

Answer: D

Model A: 6 * 4 * 2 = 48

Model B: 2 * 5 * 4 = 40

48 + 40 = 88

Can someone help me with this question
horsena [70]

Step-by-step explanation:

Given: diameter = 16 in

hence radius, r is 16 ÷ 2 = 8 in

a) notice that the fan blades divide the circle into 3 equal sectors.

Each sector is hence 1/3 of the entire circumference of the circle

Arc Length of each sector (between blades),

=  (1/3) x circumference

= (1/3) x 2πr

= (1/3) x 2 x 3.142 x 8

= 16.76 in (Answer)

b) similarly, the area between the blades

= (1/3) x πr²

= (1/3) x 3.142 x 8²

= 67.03 in² (answer)

c) The angular velocity is the radians per second that the tip moves

It is given that it moves 8π radians in 2 seconds

hence in 1 second, we expect the tip to move,

8π ÷ 2 = 4π rad/s (Answer)

there are 201 numbers from 50 to 250.

So, clearly, if 202 people are polled, at least two of them must have the same number.

-5(x+7)&lt;-10<br> solve for x
olga2289 [7]
-5(x+7)<-10.
You need to use the distributive property.
-5x - 35 < -10.
You need to cancel out -35, so you add it to itself, & -10.
-5x < 25.
You need to divide -5 by itself & 25.
x>-5.
