Describe two different methods to find the elapsed time from 2:30pm to 2:58pm

Answers

Answer 1

Answer:

Answer:

We know that:

" Elapsed time is the time or difference between a beginning time and an ending time ".

Now the two different methods to find the elapsed time is:

Method 1:

Subtract 2:30 directly from 2:58.

2:58 - 2:30 = 0:28

Hence, the elapsed time is 28 minutes.

Method 2:

Round 2:58 to 3:00, subtract 2:30 from 3:00, and at the end subtract 2 to get the desired time(2:58 + 2 = 3:00)

( Since it is easy to calculate the whole numbers).

2:58 is approximately 3:00

3:00 - 2:30 = 30 min

30 min - 2 min = 28 min.

Hence, elapsed times is 28 minutes.

Answer 2

Answer: You could substract or you can count up till you get to 2:58pm from 2:30pm

What symbol do you use for square root on pc?

Answers

For this case we must find the values of "a" and "b" that make the expressions equivalent:

We have:

$\sqrt {\frac {126xy ^ 5} {32x ^ 3}} =$

We take common factor "2" from the numerator and denominator:

$\sqrt {\frac {2 * (63xy ^ 5)} {2 * (16x ^ 3)}} =$

Eliminating common factors of numerator and denominator:

$\sqrt {\frac {63y ^ 5} {16x ^ 2}} =$

So, we have that the values of a and b are:

$a = 16\nb = 2$

Answer:

$a = 16\nb = 2$

A newly-planted tree needs to be staked with three wires. Each wire is attached to the trunk 3 feet above the ground, and then anchored to the ground 4 feet from the based of the tree. How much wire is needed for 6 trees?

Since the total amount of wire is 7, given the three feet above ground and the four feet below, there's three wires per tree, and the six trees required, the ultimate problem is 7 x 3 x 6, or 126 total feet.

Find the area of this semi circle ...

Answers

Here's the equation for the area of a semicircle: A = (πr²)/2

Based on this, let's solve for this area in terms of π (pi):

A = π(10²)/2 = 100π/2 = 50π

The area of the semicircle, I believe, is 50π. Hope this helps, let me know if I messed up!

Answer: A=157

Step-by-step explanation: The area of a semi-circle can be found using the radius in the formula A=1/2 $\pi$ r^2. We substitute the radius in the equation A=1/2*3.14*10^2

First we do the exponents following pemdas.

A=1/2*3.14*10^2

A=1/2*3.14*100

Then we multiply.

A=1/2*3.14*100

A=1.57*100

A=157

The final answer is 157.

Hope this helps!
