A circular track has a circumference of 1/4 mile. What is the radius?

Answers

The formula for circumference is $C = 2 \pi r$ . We know the circumference and therefore we can plug that into the formula and solve for the radius.

$(1)/(4) = 2 \pi r$

Lets divide by 2 first.
$(1)/(8)= \pi r$

Next, lets divide by pi.
$(1)/(8 \pi)= r$
Thus the answer is $(1)/(8 \pi)$ of a mile, which is approximately $(1)/(25.13)$ of a mile.

A gardener is planting two types of trees:Type A is three feet tall and grows at a rate of 15 inches per year.
Type B is four feet tall and grows at a rate of 10 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the same height.

Answers

First convert the feet to inches:

3 feet= 36 in.; 4 feet=48 in.

Make an equation for each one:

Type A: h=36+15x

Type B: h=48+10x

Since the questions wants the heights to be equal, h=h so you can substitute so you have:

36+15x=48+10x

5x=12

x=2 2/5 years or 2.4 years

Which choice is equivalent to the quotient shown here when x > 0?√72x^3 divide by square root of 50x^2

Answers

Answer:

$(3√(2x))/(5)$

Step-by-step explanation:

Starting point:

$(√(72x^3))/(50x^2)\n$

1) Factor it by Prime Factor Method 72 and 50

$72|2\n 36|2\n 18|2\n 9|3\n3|3\n 1\n 72=2^2*3^2*2$

$50|2\n 25|5\n 5|5\n 1\n 50=2*5^2$

2) Plug it in the factored form. Every exponent to the second power will be outside the radical, so its roots.

$(√(72x^2*x))/(50x^2)=(6x√(2x))/(5x√(2))=(6√(x))/(5√(2))$

3) Rationalize it multiplying by the radical, so that you can eliminate the square root on the denominator.

$(6√(x))/(5√(2))*(√(2))/(√(2))=(6√(2x))/(10)=(3√(2x))/(5)$

A rectangle measures fourteen centimetrers by four centimetres what is its area

Answers

The formula for finding the area of a rectangle is:
$\sf area = length * width$

Here we are given that the length is 14 cm, and the width is 4 cm.

So the are will be:

$\sf area = 14~cm * 4~cm\n\n\boxed{\sf{area = 56 cm^2}}$

The rectangles area is 56 cm. messed it up the first time!! lol
