Use the formula C= dxd
Pix diameter = Circumference
A group of students stood in a circle to play a game. The circle had a diameter of 22 meters.
Which measurement is closest to the circumference of the circle in meters?
A 34.54 m
B 1,519.76 m
C 379.94 m
D 69.08 m

Answer:

7/12

Step-by-step explanation:

I gave all of the fractions a common denominator:

1/6= 2/12

5/12= 5/12

1/4= 3/12

1/6= 2/12

Then, I added the 2/12 (from 0-1 hours) and 5/12 (from 1 1/2-2 hours). THis will give the complete range of 0-2 hours.

Hope this helps!

Answer: The function is *growing* exponentially at a rate of *0.85%* every *year*

Step-by-step explanation:

The function is growing exponentially at a rate of 0.85% every year.

The exponential decay equation is given by:-

y = (1 ± r)ⁿ

Where r is the rate of decay and A is the initial amount and n is the time period.

The function is given in the question below as:

The function f(t) = 390(1.0085)³⁶⁵ ....(i)

This represents the change in quantity over t days.

As per the given exponential decay equation,

⇒ f(t) = 390(1.0085)³⁶⁵

We can above function rewrite as:

⇒ f(t) = 390(1 + 0.0085)³⁶⁵

⇒ f(t) = 390(1 + 0.85/100)³⁶⁵

⇒ f(t) = 390(1 + 0.85%)³⁶⁵

Compare to the standard exponential decay equation, and we get

⇒ r = 0.85%

Therefore, the function is growing exponentially at a rate of 0.85% every year.

Answer:

if 'c' equals number of counters, the answer is 6c + 5

Step-by-step explanation:

david has 'c'

lisa has '5+c'

samia has '4c'

add all terms together:  c + 5 + c + 4c = 6c + 5

The formula for the total number of counters in terms of x is T = 6x + 5

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Let's start by expressing the number of counters Lisa has in terms of x. We know that Lisa has 5 more counters than David, so:

Lisa = David + 5

Lisa = x + 5

Next, we need to express the number of counters Samia has in terms of x. We know that Samia has 4 times as many counters as David, so:

Samia = 4 × David

Samia = 4x

Finally, we can express the total number of counters in terms of x by adding up the number of counters each person has:

T = David + Lisa + Samia

T = x + (x + 5) + 4x

T = 6x + 5

Therefore, the formula for the total number of counters in terms of x is T = 6x + 5.

Step-by-step explanation:

.06 =6%

The expression p(1.06)^t represents D. the yearly growth rate of the population is 6%

The country's yearly average rate of change in population size over a certain time period. It expresses the proportion, growth in population size, and the total population for that year.

Given, The population of a city can be modeled by the expression

[tex]p(1.06)^t[/tex] where t represents the number of years.

This describes the yearly growth rate of the population is 6%.

If in the previous year the population was 100 this year it'll be 106 and next year it'll be 106% of 106 which is 112.36.

Answer:

  y = x^2 +2x -8

Step-by-step explanation:

For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.

  y = (x -2)(x -(-4))

  y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property

Answer: $275

Step-by-step explanation:

The mean of the radio price is $275 or 27500 cents

Given,

Price of used original radio for a 1955 Thunderbird:

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

We need to find the mean of these prices.

And round to nearest cent.

The mean is the average of all the given sets of values.

Example:

1,2,3,4

Mean = (1+2+3+4) / 4 = 10/4 = 2.5

Find the sum

$210, $210, $320, $200, $300, $10, $340, $300, $245, $325, $700, $250, $240, $200

Sum=(210+210+320+200+300+10+340+300+245+325+700+250+240+200)

Sum = 3850

Find the number of prices.

= 14 prices

Find the mean.

= 3850 / 14

= 275

The mean radio price is $275.

Converting into cents.

$1 = 100 cents

$275 = 27500 cents

Thus the mean of the radio price is $275 or 27500 cents

Answer:

(x, y) = (-16/5, 13[tex]\frac{1}{5}[/tex])

Step-by-step explanation:

4x + 9y = 24

x + y = 10 $\Rightarrow$ x = 10 - y

Substituting the value of x (second equation) into the first equation, we get:

4 * (10 - y) + 9y = 24

40 - 4y + 9y = 24

5y = -16

y = -16/5.

So, x = 10 - (-16/5) = 10 + 3[tex]\frac{1}{5}[/tex] = 13[tex]\frac{1}{5}[/tex]

Answer:

a.

Step-by-step explanation:

this is a y = mx + b equation

the “B” is the y-intercept. So look where the line crosses the 6 axis. The equation says -1. Right away, there are only two answers that could possibly be it. A and B. The Lines both cross at -1 on the y-axis.

the ”mx“ part of the equation is the slope. Slope is the change in y over the Change in x.

in other words:

y1-y2

———

x1-x2

another thing is that slope in this equation is negative. This means the line is decreasing or going/pointing down. The only possible answer is a.
