Answer:

<u>$911.25</u>

Step-by-step explanation:

We know:

1 yd = 3 feet

So, 1 cubic yards should be *THREE* times the power of what the initial scale factor is, 3 cubed. That would make it:

1 yd = 3 feet

1^3 yd = 3^3 feet

1 cu. yd. = 27 cu. ft.

That means, the price of 1 cubic feet of sand is 27 times of the price of 1 cubic yd price

33.75 * 27 = <u>$911.25</u>

If xy=0, what must be true about either x or y
evablogger [386]

Answer:

either x or y must equal 0​

Step-by-step explanation:

ts given that xy = 0

Remember that product of two numbers can be zero only if:

Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.

So, if the product of x and y is equal to 0 there are two possibilities:

Both x and y are equal to 0

Either x or y must be equal to 0

Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.

Hence, the condition which has to be true in all cases for xy = 0 is:

either x or y must equal 0​

Find the circumference of a circular field with a diameter of 16 yards.<br> (Let it = 3.14)
Tatiana [17]

Answer:

Hey there!

The circumference of a circle is \pi(d), where d is the diameter, and \\\pi is a constant roughly equal to 3.14.

The diameter is 16, so plugging this into the equation, we get 3.14(16)=50.24.

The circumference of the circle is 50.24 yards.

Hope this helps :)

Tju [1.3M]

Answer:

Four hundredths

In standard form - 4\times 10^{-2}

Step-by-step explanation:

Given : The green darner is one of the largest dragonflies.

It weighs about four hundredths of an ounce.

To write : Four hundredths in standard form.

Solution :

Standard form is when we write a larger number in a smaller way.

For example : 20000= 2\times 10^4

So, according to question

Largest dragonflies weighs about four hundredths of an ounce.

Four hundredths means 0.04

In standard form - 4\times 10^{-2}
