Answer: About 16

Step-by-step explanation:

Given : The length of the ramp = 500 cm

The circumference of the wheel = 32 cm

We know that the number of rotations made by a wheel is given by :-

\text{No. of rotations}=\text{Length of the ramp}\div\text{ Circumference of wheel}

Therefore , the number of rotations made by each wheel = 500\div32

=15.625\approx16  [Rounded to the nearest integer.]

Hence,  each wheel will make about 16 rotations while Shawn is coasting down the ramp.

What is the value of the fourth term in the geometric sequence
ivanzaharov [21]

Answer:

a(4) = 15/4

Step-by-step explanation:

Here we're told that the first term is a(1) = 30 and that the common factor r = 1/2.

Thus, the geometric sequence formula specific to this case is

a(n) = 30(1/:2)^(n-1).

What is the fourth term?  Let n = 4,

a(4) = 30(1/2)^(4-1), or a(4) = 30(1/2)^(3), or  a(4) = 30(1/8) = 30/8, or, in reduced form,

a(4) = 15/4.

12<br> x<br> −<br> 15<br> =<br> 6<br> −<br> 3<br> x
11Alexandr11 [23.1K]

Answer:

x= 7/5 (1 2/5 or 1.4)

Step-by-step explanation:

Move the variable to the left-hand side and change its sign.

12x-15+3x=6

Move the constant to the right-hand side and change its sign.

12x+3x=6+15

Collect like terms.

15x=21

Divide both sides of the equation by 15.

x=7/5 (1 2/5 or 1.4)
