Answer:

1271.7in

Step-by-step explanation:

A complete rotation is = circumference of the wheel.

So calculate the circumference which is pi times diameter.

27 times pi (which is 3.14) = 84.78in one rotation

so if you make 15 rotations, you are multiplying it by 15

15 x 84.78 = 1271.7in

Brenda received 3 times as many grades as Robert. Timothy received half as many 85s as Brenda. How many grades of 85 did Brenda,

Diano4ka-milaya [45]

Answer:

11 grades of 85 did Brenda, Robert, and Timothy receive altogether.

Step-by-step explanation:

Let 6x be the number of 85 received by Brenda.

The number of 85 received by Robert is 1/3 of Brenda= 2x

The number of 85 received by Timothy is 1/2 of Brenda= 3x

Then according to the given conditions

6x+ 2x+ 3x

= 11x

So the number of total 85s received by all the three is 11.

11 grades of 85 did Brenda, Robert, and Timothy receive altogether.

Hi, please help me out with this math problem.

Answer:

x - 4

Step-by-step explanation:

The expression simplifies to ...

$\sqrt{x^2-8x+16}=\sqrt{(x-4)^2}=|x-4|$

For x ≥ 4, the argument of the absolute value function is non-negative, so it remains unchanged. The simplified expression is ...

x - 4 . . . . for x ≥ 4

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. 2x+3y=6

sweet-ann [11.9K]

Answer:

x-intercept: (3, 0)

y-intercept: (0, 2)

Step-by-step explanation:

For a function like:

y = f(x)

The x-intercept is the value of x when y = 0

the y-intercept is the value of y when x = 0

Also remember that an ordered pair is written as (x, y).

In this case we have the equation:

2*x + 3*y = 6

For the x-intercept, we just replace y by zero in the equation, then we get:

2*x + 3*0 = 6

Solving this for x, we get:

2*x = 6

x = 6/2 = 3

Then in this case, the ordered pair for the x-intercept is (3, 0)

For the y-intercept, we just need to replace x by zero in the equation:

2*0 + 3*y = 6

Solving this for y, we get:

3*y = 6

y = 6/3 = 2

Then the ordered pair for the y-intercept is (0, 2)
