Caitlyn’s family has a circular swimming pool. The circumference of the pool is 25.12m What is its area?

1 answer:

Answer:

A = 50.26 sq meters

Step-by-step explanation:

we have to find the diameter first by using the circumference:

C = πd

25.12 = πd

25.12/π = d

8 = d

this means the radius is 4

A = πr²

A = π4² or 16π

A = 50.26 sq meters

The table shows the types of DVDs customers rented from Sunshine Movie Rentals last year.How many comedy and action movies were

Alex787 [66]

Just borrow from the 7 and take the 1 to the 2 and that will make it as 12 so then you subtract 12 - 4 and the answer will be 1,180

Suppose we select, without looking, one marbles from a bag containing 4 red marbles and 10 green marbles.what is the probability

OlgaM077 [116]

Since 10 out of 14 marbles are green, the probability of selecting a green marble is 10/14=0.714.

Similarly, the probability of selecting a red marble would be 4/14.

Answer: 0.714

Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

hammer [34]

Answer: option d.

Step-by-step explanation:

If <em>y </em>varies directly as <em>x</em> and <em>z</em>, the form of the equation is:

$y=kxz$

Where<em> k</em> is the constant of variation.

If y=4 when x=6 and z=1 then substitute these values into the expression and solve for <em>k:</em>

$4=k(6)(1)\\4=6k\\k=\frac{4}{6}\\\\k=\frac{2}{3}$

<em> </em>Substitute the value of <em>k</em> into the expression. Then, the equation is:

$y=\frac{2}{3}xz$

To find the value of <em>y </em>when x=7 and z=4, you must substute these values into the equation. Therefore you obtain:

$y=k=\frac{2}{3}(7)(4)$

$y(7,4)=\frac{56}{3}$
