Answer:

D. 47 square units

Step-by-step explanation:

The area of the piece of red paper after the hole for the photograph has been cut is the difference between the area of large square and are of small square.

Area of large square:

The length of the side of large square is

$EF=|-4-4|=8\ units$

Area of large square $=8^2=64\ un^2.$

Area of small square:

The length of the side of large square is

$AB=\sqrt{(-3-(-2))^2+(-2-2)^2}=\sqrt{(-1)^2+(-4)^2}=\sqrt{1+16}=\sqrt{17}\ units$

Area of small square $=\sqrt{17}^2=17\ un^2.$

Difference:

$64 \ un^2-17\ un^2=47\ un^2$

The speed of light in a vacuum is 29,980,000,000

sweet [91]

Answer:

$\huge\boxed{\sf 2.998 \times 10^{10}}$

Step-by-step explanation:

Given number:

29,980,000,000

Rules:

Move the decimal point after the first non-zero digit. (after 2)
Here, we will move the decimal point 10 places to the left to move it after the first non-zero digit.
Since we move the decimal point 10 places, we will write the number as a multiple of 10¹⁰ (10 being the exponent).

The number will become:

2.998 × 10¹⁰

$\rule[225]{225}{2}$

Enzel goes online to buy a graphing calculator. He finds a site that currently has a promotion of 15% off on all orders over $50

maw [93]

<h2>Steps</h2>

So firstly, we need to find the discounted price. Since this is going to be a decrease by percentage, we will be using this format:

(1 - p)m
(p = percentage in decimal form and m = original price)

In this case:

$15\% = 0.15\\\\(1-0.15)*83\\0.85*83\\70.55$

Now that we have the discounted price, we must apply the 4.5% sales tax. Since this is going to be an increase by percentage, we will be using this format:

(1 + p)m

In this case:

$4.5\%=0.045\\\\(1+0.045)*73.55\\1.045*70.55\\73.72$

Now we have the discounted price with the sales tax. Now all we have to do is add the shipping fee:

$73.72+6.35=80.07$

<h2>Answer</h2>

The total price of Enzel's purchase is $80.07.

Liono4ka [1.6K]

Answer:

Step-by-step explenation . First you know that the amount of time she trained for the marathon is 125% of the time she trained last month. We also know that she trained 80 hours last month. And the question wants us to know how many hours she trained this month. So we do 100% =x

And 125% = 80 so we cross multiply it becomes 100 X 80 =125x witch eaquals to 8,000 divided by 125 witch is 64. So the final Answer is 64 . IF I AM CORRECT PLEASE MARK BRAINLIEST.
