The formula for the circumference, C, of a circle with given radius, r, is C = 2nr.

Mathematics
1 answer:
LekaFEV [45]3 years ago
6 0

Answer:

C. 22

Step-by-step explanation:

C = circumference

n (pi) = 22/7

r = 3 1 /2

Plug in the numbers for each variable.

C = 2x (22/7) x (3 1/2)

Change the mixed number inIto an improper fraction by multiplying 3 x 2 and adding the 1 which gives us 7 over 2 because 2 is our denominator  so, 3 1/2 = 7/2. It also helps to have 1 as the denominator for 2.

C = (2/1) x (22/7) x (7/2)

Lastly, just multiply the numerators across which give us 308 then multiply the denominators across which gives us 14, so then we divide 308 by 14 and get 22.

a nutrition major at wright state was studying the relationship between carbohydrates (x) and calories (y). for example, a servi
VLD [36.1K]

Answer:

The predicted calories would be 403 calories.

Step-by-step explanation:

We have a linear regression model relating y: calories with x: carbohydrates, which has a slope of 4.0 and a y-intercept of 3.0.

Then, the model equation is:

y=4.0x+3.0

With these model we can predict the calories values for any amount of carbohydrates, within the interval within which this model is valid.

If a new food is tested, and the number of carbohydrates (x) is 100, the predicted value will be:

y(100)=4.0(100)+3.0=400+3=403

The predicted calories would be 403 calories.

Which of the following polynomials is a binomial
Dima020 [189]
Hey there!

A binomial is a polynomial that contains two terms. Terms are separated from one another by mathematical symbols, such as +, –, and ×. A term can be a variable, a variable with a coefficient, a constant, or really any combination of coefficient, variable, and exponent that you can think of. For example...

(3x² – xy)

(x + 3)

(5x – 6y)

...are all binomials. 

Hope this helped you out! :-)

Answer:

Zero

Step-by-step explanation:

Slope is:

\frac{Change of y}{Change of x}

Since there is no change of the y value, there is no slope.

The graph shows a proportional relationship between the number of kilometers traveled by a bicycle (y) and the number of minutes
yaroslaw [1]

The unit rate of the bicycle is 0.3 kilometers per minute.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept (initial value of y).

Let y represent the km travelled by the bicycle after x minutes. From the graph using the point (0, 0) and (40, 12), hence:

Unit rate (m) = (12 - 0)/(40 - 0) = 0.3 km/min

The unit rate of the bicycle is 0.3 kilometers per minute.
